LARGE MAGNETIC FEATURES DETECTED AT RUBY
PROJECT
The
Companys recently completed regional magnetic survey has shown that
known magnetic anomalies underlying high grade ruby gravels are part of
a newly mapped and far larger magnetic feature.
The previously mapped anomalies were investigated to determine their nature,
and whether they may guide the Company to a hard rock source for the alluvial
rubies being produced. The magnetic map produced is shown as Figures 1
and 2, and an interpretation as Figure 3. The area of the previous magnetic
survey and drilling is shown on these figures as Brazier Flat.
The larger and prominent circular magnetic feature comprises two concentric
magnetic lows, from 70 to 150 metres wide, with diameters of 700 metres
and 1,500 metres respectively. Small parts of two similar concentric features,
but with far larger diameters, may have been detected further to the west.
Several pits dug into one of the concentric low (blue) anomalies, and
beneath the Upper Terrace gravels, have shown areas of granite bedrock
which has been decomposed, possibly by the action of hot spring activity
in the past. Indeed, many of these magnetically low zones form boggy areas
at present, suggesting that springs may still be active beneath them.
Pits dug into the high (red) anomalies penetrated fresh granite bedrock,
or granite boulders, suggesting that spring activity has been less intense
here. Within the Upper Terrace pit currently being excavated, such a magnetic
high consisted of large unweathered boulders. Low grades were present
over this zone (Sections 6 and 7), but channels scouring out both sides
of it (Sections 8, 9 and 14) contained the highest ruby grades recovered
to date.
The large, circular low anomalies are interpreted by the Company to have
formed by release of gasses, including water, emanating from a volcanic
intrusion beneath the central area of the anomaly, but at depth. Whether
small parts of such an intrusion have been exposed at the surface, and
whether such intrusive activity could transport rubies to the surface,
allowing them to be concentrated in the overlying gravels, is being investigated.
Initial geological mapping and magnetic modelling will be used to locate
drill holes or trenches searching for a hard rock ruby source.

Trial Underground Production to commence
on Copeton Diamond Field
The
Company has commenced seeking tenders for sinking of a two metre by two
and a half metre shaft to fifty metres depth on the Davis Block, at Mount
Ross, Copeton. When the shaft is completed, a two and a half metres wide
tunnel will be driven for fifty metres from its base across a buried river
channel. The tunnel aims to recover diamonds from sediments at the base
of the river, and determine their size, quality and value on the present
wholesale market, to allow calculation of average grade for the part of
the deposit accessed. An experienced mining contractor will carry out
the mining program. It is budgeted at half a million dollars, and will
be funded from monies received from the exercise of the Companys
options during December.
The shaft is to be sunk between the Mount Ross Shaft and the Syndicate
No 1 Shaft, in the centre of the Davis Block (See Figure 1 below).
The shaft and tunnel will provide access to an inferred resource of 200,000
tonnes of diamond bearing sediments with a grade of 250 carats of gem
quality diamonds per hundred tonnes (see Figure 2 below). 2 kg/tonne of
cassiterite (tin oxide) is also inferred. This exceptionally high grade
is reported in mining literature of the early nineteenth century. Cluffs
mining aims to confirm these high diamond grades, and allow determination
of the most suitable mining methods for diamond production by the Company.
Confirmation is expected that tunnelling in the inferred resource last
century was very limited.
This Davis Block is the extension deeper beneath Mount Ross of the diamond
bearing river channel worked nearer its outcrop by the Inverell Diamond
Fields Company from 1897 to 1904 by the Deep Shaft, and then by the Deep
Shaft Company until 1911. Four shafts subsequently accessed this Block,
with high grades reported, but no large scale production has since been
recorded. The Mount Ross Diamond and Tin Mining Company, which subsequently
held this Block, had labour conditions suspended in 1916, perhaps due
to a manpower shortage during the First World War. The Davis Block is
additional to the inferred resource of one million tonnes at 50 carats
per hundred tonnes reported in 1999, based on underground operations and
diamond recovery by Audimco Limited, the company from which Cluff purchased
the Copeton mining leases.
If the shaft and tunnel successfully produce economic diamond grades,
a second shaft will be established for safety and ventilation reasons,
a permanent headframe will be installed, and the most suitable production
method for the mining conditions will be trialed. Diamond bearing gravels
produced will be processed through Cluffs currently operating trommel
and jig plant, with a 2 km haul.
Whilst water deposited sediments are being targeted in this appraisal,
the diamonds previously extracted from the Copeton deposits show few signs
of long alluvial transport, and underground access is expected to provide
further evidence of a local origin for these diamonds.
Although mine development on an inferred resource entails risks, the Boards
opinion is that the cost of this shaft sinking is small in relation to
potential profits. Much of the cost of developing a mine at Copeton has
already been expended, with mining leases granted, exploration drilling
completed, and a production plant operational on site. This underground
development aims to capitalise on previous expenditure by the Company,
and to quickly establish a positive cash flow for the Company as a diamond
producer with access to half a million carats of gem quality diamonds.
Because of the unusual nature of the inferred resource calculation, a
definition of an inferred resource, and the data upon which this one is
based, is included in this report.
TECHNICAL REPORT - INFERRED RESOURCE
An inferred resource is one for which tonnage, grade and mineral content
can be estimated with a low level of confidence. This resource is inferred,
firstly from geological evidence of a buried river channel based on drilling
by Cluff, and by Audimco Ltd during the 1970s and, secondly, from assumed
but not verified geological continuity and grade continuity based on statements
in century old publications. These state that exploratory tunnels were
in a continuous run of diamond wash, and refer to the patchy nature of
the alluvial, with spectacularly high grades interspersed with lower grades.
Within the inferred resource there may be areas below the selected cut
off grade to ensure that the inferred mineral resource comprises a body
of mineralisation of adequate size and continuity to properly consider
mining. The location of such areas is uncertain, and inferred average
grades are used in this resource.
Basis of Inferred Resource
The inferred resource is based on information gathered through shafts,
tunnels, small mined areas, and drill holes. Shaft and tunnel information
is of uncertain quality
because although shafts have been reliably identified, the location of
the tunnels extending from them, and small mined areas accessed by the
tunnels is not known in most cases. The sources for the information include
reports of the NSW Mines Department, contemporary newspaper reports, particularly
the Australian Mining Standard, and a prospectus for the Mount Ross Diamond
and Tin Mining Company NL, together with subsequent company reports. Many
of these reports were written in an imprecise manner, and relied on field
correspondents for their content, but the large number of sources provides
generally consistent information.
Due to the uncertainty attached to this inferred mineral resource, it
cannot be assumed that all or part of it will be upgraded to an indicated
mineral resource as a result of continued evaluation. Confidence in the
estimate is not sufficient to allow appropriate application of technical
or economic parameters, or to enable an evaluation of economic viability.
This inferred resource should not be used in economic studies.
Geology
The deposit of diamonds occurs in a "deep lead" (buried river
channel) present beneath about fifty metres of basalt lava and lake sediments.
The diamonds occur in extremely high grade "patches" within
gravels and "wash" of the former river channel. The river deposits
are about 120 metres wide, and the inferred resource extends along 450
metres of its length. To the south these river channel deposits were worked
out during the period 1897 to 1911. They extent to the north for at least
another 400 metres, but insufficient data is available to quantify the
deposit in this area. The river predates the overlying basalt lavas, and
was active before about 50 million years ago.
Nature, Quality and Value of Diamonds
1. Bulk sampling by Cluff and previous workers has shown that more than
90% of diamonds recovered during bulk sampling in many parts of Mt Ross,
and the Copeton field, are of gem quality.
2. At Deep Shaft, Cotton (1915) notes that "the stones average three
to the carat and are of good quality. From 40 to 50% of the stones are
white, rather more are a light yellow, while a few are brown and green.
Octahedral stones are conspicuous; probably 6 to 8 % of the diamonds being
of this nature. A number of the crystals exhibit twinning. Pieces of Bort,
several carats in weight, have also been found at this mine."
3. No microdiamonds have been identified on the Copeton Field. The minimum
size of diamonds recovered by the Company during previous testing was
0.7 mm.
4. Based on Mt Ross DTM Co (1911), the composition of a sample of 707
carats in the Syndicate No 1 Shaft area was reconstructed as below:

Mining Method Assumptions
Mining methods will be assessed when access to the inferred resource is
obtained.
Metallurgical Assumptions
Using a trommel and jig plant or diamond pan, both of which are owned
by Cluff, a recovery of diamonds well in excess of 90% is anticipated.
Cut-off Grades
Available descriptions of the diamond bearing gravels state that highest
grades are in a thin layer at the basement contact (Idress, 1948). This
is common in river deposits. It is therefore assumed that wherever the
base of the river deposit has not been eroded, the rich layer carrying
the bulk of the diamonds is present, and the extent of this layer has
been taken as the cut off of the extent of the resource.
Extreme Grade Treatment
In reporting grades, only grades from larger bulk samples or small scale
mining, and statements as to the average grade throughout the mine have
been used. Many instances of spectacularly rich grades are reported in
the literature, but it is also stated in the literature that these will
be averaged downwards by areas in which grades are poor (AMS, 1902). Hence
the high grades have not been utilised in preparation of the inferred
resource.
Previous Extraction of the Inferred Resource
Four shafts (Syndicate No 1, Mount Ross, Hills and Heath No 1, Davis)
are recorded as accessing the inferred resource during the period 1911
to 1916. Available information indicates that the Mount Ross DTM Company,
which owned the leases during that period, produced only about 2,600 carats.
Total production recorded by the Mines Department from the Copeton field
from 1912 to 1916 was 10,000 carats. Mines Department records show only
prospectors working in the areas of the inferred resource after this period.
Hence it is unlikely that large areas of the resource have been extracted.
It is assumed, however, that 10% of the resource has been mined.
Portions of the deposit are considered to have reasonable prospects for
eventual economic extraction, based on reported tunnelling and mining
of small areas withinup to 1916, after which little production was recorded
by the NSW Mines Department from this area of Mount Ross.
Potential of the Deposit
Comments in square brackets are by the author.
1. AMS (1913) (December 4) reports "As there is a large scope of
deep country extending into the hills still unprospected, there is every
reason to believe that development work will locate rich runs in the deeper
ground as this feature has characterised past operations".
2. Australian Mining Notes (1909-1913) states that "A low level tunnel
is beyond the prospectors finances
.Consequently upon this field
acres and acres of ground, extending into the deep country in the hills,
are unprospected, with every chance of being just as rich as were the
surface shows.
3. AMS (1911) (November 30). "Some years ago, a rock shaft [Mount
Ross Shaft] was commenced by the Star Company. It was abandoned after
being sunk for about 40 feet. Rich faces, which were not easy to reach
from the main shaft, were proved to extend in that direction, and the
work promised well to repay expenditure. The Mount Ross Co. intends to
bottom this shaft. The prospect of rich faces in this direction is almost
assured, apart from what the Star Company left. The Deep Shaft Company
is driving in the direction of the work proposed to be done by the new
Company, and there is every chance of their meeting a similar rich deposit
to that found in the Deep Shaft Mine." [The Company subsequently
deepened the Shaft, and referred to "Ross" water drive,
suggesting there may have been water problems encountered in mining. These
can be now be addressed using modern mining techniques.]
4. AMS (1913), (December 4), reports that "The Rossmount Company
own several [leases], occupying important positions in the centre diamondiferous
area. One of these blocks as the "Deep Shaft" mine
holds a prominent place amongst the diamond claims held, gems weighing
up to four carats being obtained from it. The adjoining block, formerly
known as "Daviss Shaft", has also produced deposits of
tin and diamonds. As there is a scope of deep country extending into the
hill still unprospected, there is every reason to expect that development
work will locate rich runs."
Tonnage Estimation Technique
The resource tonnage was estimated by preparation of five cross sections
across the deposit at 100 metre spacings, based on drillholes. The area
of diamond bearing sediments was determined, assuming each section represented
an area extending fifty metres to either side. A working thickness of
two metres was assumed throughout the deposit, as this is the minimum
that can be extracted by modern bulk mining techniques. The layer of diamond
bearing material is always thinner than this, and the overlying lower
grade or barren rocks, which also must be extracted, will dilute its grade.
Tonnage was determined by using an in situ density of two tonnes per bank
cubic metre, based on testing by Audimco Ltd during the 1970s.
Grade
Estimation Techniques
Grades in the "wash" reported below were corrected to a two
metre thickness, assuming overlying material is barren. Notes in square
brackets are explanatory additions by the author.
All grades in the past literature are in carats per "load".
McNevin (1973) states that "a load comprised about three-quarters
of a cubic metre of washdirt, and roughly approximated to one t.".
Pittman (1901) describes the throughput of the Star of the South Mine
as 300 cu yards per day in one part of his text, and as 300 loads per
day in another. Assuming a load is one cubic yard, it would equate to
0.765 cubic metres. Field Geologists Manual (2000) gives a density for
unconsolidated dry gravel after excavation of 1.4 g/cm3. Hence one cubic
metre of dry gravel would weigh 1.4 tonnes, and 0.765 cubic metres (one
load) would weigh 1.07 tonnes. For calculations below it has been assumed
that mine measurements were approximate, and one load equals one tonne.
Line 9700 (Grade Assumed 150 carats per hundred tonnes)
1. Daily Telegraph, (1911), April 13, reports "The wash showing in
the faces averages a thickness of about 2 ft, and produces about 50 lb
of stream tin per load. The estimated diamond deposit of this claim [Deep
Shaft Mine] averages 6 carats to the load throughout the mine." [This
represents a grade corrected to a two metre thickness of 180 carats per
hundred tonnes average for the mine.]
2. NSW Mines Department (1909) reports the recovery at Deep Shaft of 2,260
carats of diamonds from 224 loads of wash. Assuming a thickness for the
"wash" of 0.3 metres (Cotton, 1915), this represents a grade
of 151 carats per hundred tonnes. As production had only recommenced in
about 1907, this is very likely from near this line, on the southern part
of the lease, near Deep Shaft. It is also likely to be from development
drives and hence representative of grades over extensive areas.
3. This grade is consistent with the average cut off grade of 187 carats
per hundred tonnes over an undefined thickness being worked by the Inverell
Diamond Fields Company at their mines (including Deep Shaft) when its
mining operations were shut down (AMS, 1902).
Line 9800 (Grade assumed 200 carats per hundred tonnes)
1. AMS (1911) reported that "for the whole of the distance between
these two shafts [beneath Line 9800] a continuous run of diamond wash
has been met with".
2. It was reported (Mt Ross DTM Co, 1911) that a party of miners followed
the lead for 700 feet to the north and northeast with improving values
towards the centre of the Mount Ross Block [beneath this section and to
its north].
Line 9900 (Grade assumed 260 carats per hundred tonnes)
1. AMS (1911) (20 April) reports, [apparently beneath Syndicate No 1 Shaft,]
that the wash showing in the faces averages about two feet thick, and
produces about 50 lbs of stream tin and 6 carats of diamonds to the load.
This represents 180 carats of diamonds per hundred tonnes and 6 kg of
SnO2 per tonne over a two metre working thickness.
2. AMS (1911) (3 August) reports that "this rich diamond deposit
(which is two feet thick) is estimated in prospects washed from the face
to yield 150 carats per load." [This represents 4,500 carats per
hundred tonnes over a two metre working thickness].
3. AMS (1911) (17 August) reports further rich developments, and the wash
has increased from two feet to six feet in thickness.
4. AMS, (1911) (31 August). The Deep Shaft Party were on a very rich face
of diamond wash, going from 20 carats to 150 carats to the load, and the
depth of wash varies from 2 feet to 6 feet. [This averages a grade in
excess of 600 carats per hundred tonnes over a two metre working thickness].
5. AMS (1911) (October 5), referring to Syndicate No 1 Shaft, states "In
blocking out here a space of 18 ft by 20 ft produced over a thousand carats
of diamonds." [This represents a grade of 750 carats per tonne over
a two metre working thickness].
6. NSW Department of Mines (1911) reports 2,000 carats from 50 loads [600
carats per hundred tonnes], almost certainly from this area.
Line 10000 (Grade assumed to be 300 carats per hundred tonnes)
1. Cross (1911) "inspected the drives [north from Syndicate No 1
Shaft] extending to 150 feet from the boundary of the Davis property.
The wash is heavy in the eastern drive [suggesting that there were two
drives], and varies from two feet to six feet in depth. They have driven
from the new shaft [Syndicate No 1] about 100 feet, with improving results
going in a north easterly direction, and although cross drives have been
put in at intervals, the width of the lead is not known, as it has not
been crossed".Because of "improving results", a grade of
300 carats per hundred tonnes has been assumed for this area.
Line 10100 (Grade assumed to be 300 carats per hundred tonnes)
This line, to the north of the Mount Ross Shaft, is on the Davis Block.
2. Cross (1911) states "They have large heavy wash there; so was
the Davis as far as they went. All the wash in the Davis block taken out
was rich in tin and diamonds".
3. Cross (1911) continues "On the western side [of the Davis Block]
both ends of the workings are rich. The eastern run [of the Davis Block,
and almost certainly within the inferred resource] is, in my opinion,
far better than anything that has yet been seen, as only the shallow and
dry ground has been worked.
4. AMS (1911) (30 November) states that "During the time that the
Star Co held this ground, [Daviss Block] rich faces were exposed
in drives extending beyond this shaft. Some years ago a rock shaft was
commenced by the Star Company. It was abandoned after being sunk for about
40 feet. Rich faces which were not easy to reach from the main shaft were
proved to exist in that direction and the work promised well to repay
expenditure. The Mount Ross Company intends to bottom this shaft. The
prospect of rich faces in this direction is almost assured, apart from
what the Star Company left.
5. At Hills and Heath No 1, AMS (1921) (8 September) from a primitive
trial of this wash deposit a bucketful or two four diamonds
were obtained. The Party, on indications revealed, are almost sure to
open up rich tin and diamond bearing wash.
6. On this basis a grade continuation to the north of 300 carats per hundred
tonnes is assumed for this line.

Assuming 10% of the deposit is worked out, with rounding off of the figures,
this represents an available tonnage of 200,000 tonnes at an average grade
of 250 carats per hundred tonnes.
Technical Data
Drillholes utilised in the study include composite percussion, blade and
core drilled holes, and Calweld large diameter holes, and were professionally
logged. In most cases the river channel was drilled by blade bit, and
logged by cuttings. 35 drillholes were utilised in the interpretation.
A diamond was recovered from one Calweld drillhole, and from mullock around
shafts. Processing was by a small attrition mill and jig. Holes were located
by theodolite survey. This drilling density is sufficient to establish
continuity of the deep lead deposit over the area studied.
Tenure
The resource is located on MLs 1058, 1083, 5904 and ELA 1952. The area
is owned by the Department of Land and Water Conservation, and is partly
within a reserve managed by the local Council.

Gloucester Ruby Project - 23,755 carats
of uncut ruby from pit sections 13, 14 and 15
Processing
of 538 tonnes of ruby bearing gravels from Section 13, Strip 3 (28 to
48 metres from the river end of the pit) yielded a total of 10,710 carats
of uncut ruby: 7,370 carats of facet quality and 3,340 carats of cabachon
quality. This represents a grade of 19.9 carats per tonne saleable to
CPH Limited. Wash thickness ranged from 1.3 to 2metres, and overburden
thickness ranged from 0 to 1 metre.
260 tonnes of gravels were processed from Section 14, yielding a total
of 8,782 carats of uncut ruby: 5,681 carats of facet quality and 3,101
carats of cabachon quality. The resultant grade was 33.7 carats per tonne
the second-highest grade obtained at the ruby project so far. Wash
thickness ranged from 1.1 to 1.3 metres and there was no overburden.
Section 15, located 75 to 55 metres along Strip 3, yielded 4, 263 carats
of uncut ruby from 304 tonnes processed: 3,154 carats of facet quality
and 1,109 carats of cabachon quality, with a resultant grade of 14 carats
per tonne. Wash thickness averaged 0.8 metres, in line with the adjacent
Section 6.

Letter to Optionholders
The
following letter has been sent this week to all holders of December 31,
2003 Options (CFRO), regarding the conversion of the options to ordinary
shares (CFR). We wish to draw shareholders particular attention
to the proposed activities at Mount Ross as described in Diamonds
below:
Dear
Optionholder,
CLUFFS FUTURE WORK PROGRAM
Cluff Resources has been very active in recent months, particularly, since
agreement was reached with Consolidated Press Holdings Ltd for the development
of the ruby project. With your support, by converting your December 2003
options to Cluff ordinary shares for 4 cents per share, the Board intends
to maintain this momentum towards establishing viable mining operations
and thereby achieving a positive cash flow.
ACHIEVEMENTS
Since dispatch of the Annual Report, the Company has steadily progressed
towards our objective. Particular highlights include the following.
- Cluff
reached agreement with CPH on the Gloucester Ruby Project, whereby both
Companies contribute in their areas of specialisation. Subject to the
successful outcome of the current trial marketing operation and a feasibility
study, Cluff will mine and process rubies which it will sell to CPH
at a fixed mark up. CPH will market the stone and derived jewelry products,
remitting 20% of the net profits of that operation to Cluff.
- Cluff
is currently producing gemstones from a designated trial mining area,
and selling this production to CPH. Your Company has refurbished its
production plant, mined 6,000 tonnes of gravels, and produced 77,700
carats of rough ruby and about 8,000 carats of rough sapphire to date.
- Top
quality contract cutting of the gems by CPH is in progress, and finished
stones have been shown to the trade, with very favourable comments on
their brilliance. CPH is cutting the stones and conducting the market
investigation at its own cost. The result is Australias first
trial ruby mining and marketing operation.
- On
diamond exploration, a new geological model has been developed by Cluff
to explain the origin of the Copeton/Bingara diamonds, and diamonds
in unconventional rocks have been demonstrated
For
further details of the Companys operations see our website: www.cluff.com.au.
THE
FUTURE
Gloucester Ruby Project
- Cluff
plans to continue ruby production at the present rate, subject to CPHs
positive decision to progress to a feasibility study for a large-scale
mining operation. This study will investigate the economics of Cluff
constructing a new plant designed to process 1,500 tonnes per day of
ruby bearing gravels, with Cluff selling ruby concentrates to CPH and
participating in net profits from CPHs marketing operations.
- According
to CPHs merchandising consultant, Mr Gerry Manning of New York
based Manning International, the deposit has the potential to be a "single
source for a full rainbow palette" of highest quality untreated
gemstones.
- Cluff
will search for the primary ruby source. A large hard rock source may
warrant long term mining, possibly with more regular ruby quality. A
recent extensive ground magnetic survey has already indicated target
areas.
- Ruby
deposits known in the surrounding areas will be prospected to increase
the resource.
Diamonds
- A
shaft is to be sunk forty metres to confirm diamond grade and quality
in a high grade exploration target at Mount Ross, on the Copeton diamond

Drilling
for diamonds at Bingara completed
Sixteen large diameter
drill holes were completed on the Bingara Diamond Field in the recent
drilling program. Three infilled shafts from the 1890s were also drilled
out to determine the level the Melbourne and Bingara Diamond Company was
evaluating. The holes, up to fifteen metres in depth and 0.7 metres in
diameter, aimed to find diamond bearing conglomerates at the base of a
raised terrace of river gravels on the Four Mile Creek area. Drilling
totaled 220 metres.
The diagram below
shows the location of these activities:
All holes were drilled
to hard basement shales. The basal river gravels were penetrated in six
of the holes, and four samples of between 0.5 and 1.5 tonnes were taken
for testing for diamonds. In the other ten holes the basal river gravels
were not present, and up to eight metres of extremely altered and broken
claystone with bedrock fragments at its base sits on the basement. The
basal river gravels appear to have been eroding into this clay.
The upper part of this claystone has been tested previously, and
did not contain diamonds, but nonetheless was sampled in two holes. The
basal part, with bedrock fragments, has not been tested before, and six
samples of this, ranging from 0.5 to 2.5 tonnes, will be processed for
diamond content. Although the origin of the clay with bedrock fragments
is uncertain, the Company believes that testing for diamonds is warranted.
In one hole, drilled next to an 1890s shaft, 0.4 metres of this zone was
backfilled with loose sand, suggesting that rocks from this zone were
removed for diamond (or gold) testing during that period.
Thirteen samples are now stockpiled on site, and rather than transport
them to Mount Ross for processing, the Company's small transportable processing
plant has been set up at Bingara, and is expected to commence processing
of the samples tomorrow.
A ten metre deep pit
will be commenced this week to excavate a sample of about sixty tonnes
of rock from the horizon previously sampled by the 1890s operators
near drillhole CR37. This will be transported to Mount Ross for processing.
The diamond deposit occurs on EL 3325 held by Cluff Minerals (Australia)
Pty Ltd, a subsidiary of the Company. It is subject to an agreement with
Diamond Ventures Exploration Pty Ltd whereby that Company receives a Net
Profit Interest of 10% before DVE has received NPI payments totaling $2
million, and 5% thereafter.

Extension
of Ground Magnetic Survey - Gloucester Ruby Project
A
ground magnetic survey investigating the regional extent of the magnetic
anomalies underlying high grade ruby gravels has been commenced.
This survey follows up the trial ground magnetic survey completed in September,
which suggested a relationship between magnetic anomalies and the occurrence
of high grades of ruby in the overlying gravels. The survey aims to map
the regional setting and extent of these anomalies, and may assist in
locating a primary source for the rubies.
The survey will extend over an area approximately 5 km by 1 km. It will
generally be carried out by walking using 50 metre line spacings, with
intermediate lines giving a 25 metre line spacing over areas of possible
significance. Fieldwork for the survey is expected to be completed in
about a week. The resultant map will be released shortly thereafter, when
the field data has been processed. Subsequent interpretation of the survey
will take some time.
Digital Terrain Modelling for the Gummi River Valley will be carried out
concurrently with this survey, as a base line study for the Environmental
Impact Statement which will need to be prepared prior to larger scale
mining.
The ruby deposit occurs on EL 5336 held by NSW Gold, a 100% subsidiary
of the Company, and is subject to a business arrangement with Consolidated
Press Holdings Limited.

Diamond
Exploration Program commences at Bingara
A
large diameter drilling program exploring for diamonds has commenced on
the Four Mile Creek area of the Bingara Diamond Field in northern NSW.
This was an area evaluated by the Melbourne and Bingara Diamond Mining
Company during the early 1890s and extends about 1 km by 0.5 km.
Mr G. Stonier, Geological Surveyor, reported in the 1894 Annual Report
of the NSW Department of Mines and Agriculture:
"A large amount of work well distributed over the blocks has been
done, and in all a dozen shafts have been sunk, mostly through drift,
with depths varying from 14 to 64 feet, a number of shafts of a lesser
depth, and several cuttings. On Portion 134 the wash runs up to 8 feet
In thickness, and averages 5 feet, and on Mineral Lease 9 the average
is from 3 to 4 feet. Mr Mercer, the Manager, estimates that both blocks
will yield an average of half a carat to the load. Records have been kept
of various washings, and they account for 221 carats of diamonds, and
15 oz. gold from 220 loads on Portion 134, and 130 carats from 202 loads
on Portion 9." (Note: A load roughly approximated to one tonne).
These basal gravels cover about 1 km by 0.5 km. Reported shaft depths
indicate that the gravels fill a shallow basin, the edge of which was
tested by several pits of about five metres depth by Cluff during the
early 1990s with low grades of diamonds recovered. The current drilling
aims to test the nature of the gravels and diamond content in the centre
of this structure, where modern testing has not been carried out.
The holes drilled will be 0.7 metre diameter, and each is expected to
yield several tonnes of gravel, which will be processed through the Company's
processing plant at Mount Ross, Copeton, to determine diamond content.
The diamond deposit occurs on EL 3325 held by Cluff Minerals (Australia)
Pty Ltd, a subsidiary of the Company. It is subject to an agreement with
Diamond Ventures Exploration Pty Ltd whereby that Company receives a Net

Section 8 gravels
mined ranged in thickness from 1.4 to 1.7 metres, averaging 1.5 metres.
Overburden thickness averaged 2 metres. Processing of other sections at
our trommel and jig plant is continuing at the rate of approximately 150
tonnes per day, and concentrate continues to be upgraded through our Sydney
facility.
This section and the adjoining section 9 encountered a deep channel filled
with gravels. This was created by the river flowing around higher basement
rock with granite boulders which underlies section 6/7. A similar channel
has been cut on the southern side of the higher basement rock underlying
sections 4 and 5.
The ruby deposit occurs on EL 5336 held by NSW Gold, a
100% subsidiary of the Company. It is subject to a business arrangement
with Consolidated Press Holdings by which Cluff Resources Pacific NL will
receive 20% of the net profits from sale of gemstones marketed by CPH.

Gloucester
Ruby Project - highest grade recorded to date: 33 carats per tonne
14,679
carats of uncut ruby were recovered from Section 9, Strip 2 yielding a
grade of 33.3 carats/tonne, the highest recorded to date from the project.
Processing of 441 tonnes of gravel, extracted from 90 to 99 metres along
Section 9 of Strip 2, yielded a total of 9,617 carats of facet quality
uncut ruby and 5,062 carats of cabachon grade, totalling 14,679 carats
of uncut ruby saleable to CPH Limited. This represents a grade of 33.3
carats per tonne the highest grade recorded to date at the Gloucester
Ruby Project. All stone reported is greater than 2 mm in diameter.
Ruby bearing gravels were continuous along the length of Strip 2, being
thick in Sections 8 and 9 (about 2 metres) and thin (about 0.7metres)
throughout Sections 6 and 7.
Sections 6 to 8 are currently being processed at our Sydney facilities.
Section 9 was processed first due to the large volume of concentrate extracted,
warranting priority. Sections 6 and 7 yielded far less heavy concentrate,
and are expected to carry lower grades of ruby. The Table below shows
results to date, and the Figure shows the locations of the Sections with
respect to the pit excavation area. The Photograph shows Strip 2, looking

Ruby Project - 9,400 carats of uncut ruby from sections 4 and 5, strip
2
Strip
2 of the ruby mine, seven metres in width and contiguous to Strip 1, has
progressed northwards, from 0 to 45 metres through gravels with a clayey
matrix for the two sections reported below, then through a zone of boulders
up to 80 metres, and through a channel with sandy gravels between this
zone and 99 metres. Strip 3 has now commenced.
Processing of 361 tonnes of ruby bearing clayey gravels from Section 4,
Strip 2 (0 to 19 metres measured from the southern end of Strip 2) yielded
a total of 1,650 carats of facet quality uncut ruby and 703 carats of
cabachon grade uncut ruby. This represents a grade of 6.6 carats per tonne
saleable to CPH. As cabachon quality stone (cut with a rounded polished
surface and popular in Asian countries) grades into low value corundum,
CPH will at a later stage be conducting test polishing of this stone to
confirm Cluff's grading of cabachon stone.
Processing of 521 tonnes of ruby-bearing gravels, from Section 5, Strip
2 (19 to 45 metres along Strip 2) yielded a total of 4,175 carats of facet
quality uncut ruby and 2,872 carats of cabachon grade. This represents
a grade of 13.5 carats per tonne. The higher grade is probably due to
the sandier nature of the gravel. All stone reported is greater than 2
mm in diameter.
Ruby bearing gravels have been continuous along this section of Strip
2, range in thickness from 0.5 to 1.95 metres, averaging 1.2 metres. Overburden
thickness averaged 2.3 metres. Processing is continuing at the rate of
approximately 150 tonnes per day, and concentrate continues to be upgraded
through our Sydney facility.

of the latest 520 tonnes of gravels, which were extracted from 55 to 110
metres along Section 2/3 of Strip 1, yielded a total of 5,625 carats of
uncut ruby suitable for sale to CPH Limited. This represents a grade of
10.8 carats per tonne. Additional ruby suitable for alternative cutting
processes is also being evaluated by CPH Limited for its marketing potential.
All stone reported is greater than 2 mm in diameter.
Ruby bearing gravels have been continuous along this strip, averaging
1.2 metres in thickness. Overburden thickness averaged 2.2 metres. A second
strip, which is 7 metres in width and is contiguous to the first, has
now been excavated and mining is proceeding. Processing is continuing

First
production yields 10,027 carats of uncut ruby
Commissioning
of the upgraded plant at the Gloucester Ruby Project has been successfully
completed. During the 3.75 day trial 560 tonnes of ruby bearing gravel
were treated, with a throughput of 150 tonnes per day. As the plant was
being fine tuned during this period,material was fed into it slowly, and
there were small delays. It is anticipated that the plant is capable of
treating gravels at a substantially higher rate. An upgraded concentrate
processing circuit using heavy liquid separation was also successfully
trialled, eliminating the need for costly hand picking of the ruby before
sale.
The initial trench of the pit has been excavated to 100 metres length,
and a stockpile of gravels is being created to ensure continuous feed
for the plant. Excavation of the second cutof the pit is now commencing.
Ruby bearing gravels have been continuous along the length of
the trench averaging about 1.2 metres in thickness, but varying from over
two metres in the deeper channels to about 0.6 metres over small basement
highs. The trench commenced near the northern edge of the Upper Terrace
channel, and has not yet intersected the southern edge of the channel.
Gravels at the end of the trench are 0.8 metres thick and continuing.
Processing of the 560 tonnes of gravels yielded 10,027 carats of uncut
ruby. This represents a grade of 17.9 carats per tonne. The stone is of
good quality and colour, ranging from deep red through deeper pinks to
a very pale pink reminiscent of Argyle pink diamonds. Only ruby of quality
suitable for sale to Consolidated Press Holdings has been included in
this grade. All stone reported is greater than 2 mm in diameter. Production
at the mine is continuing at 150 tonnes per day.

Magnetic
anomalies beneath ruby gravels
Strong magnetic anomalies have been detected beneath the higher grade
zones of the Upper Terrace ruby bearing gravels by the ground magnetic
survey completed recently (see attached
figure - Acrobat PDF format). If these anomalies are produced by rocks
containing the rubies, ground magnetic surveys may be a means to quickly
locate high grade gravels, and the underlying source rocks for the rubies.
Several pits will be completed in the next month to expose the bedrock
beneath anomalies to determine their nature and economic significance.
The ground magnetic survey was carried out by walking, with line spacings
of ten metres and positions determined by differential GPS. Differential
in magnetic intensity between dark blue areas and red areas is high, at
approximately 400nT.
Much of the area surveyed has a gently undulating magnetic pattern in
the orange to green-blue range, which probably represents the normal granite
bedrock. In some areas this grades to a light blue colour, possibly caused
by breakdown of magnetic minerals within the granite by hot watery gases
which have moved through it in the past. Neither pattern underlies high
grade ruby gravels.
Very sharp anomalies about 20 by 30 metres in size and in places coalesced
and forming linear zones, are both normally and reversely magnetised,
giving very intense deep blue or red colours. That they originate immediately
beneath the gravels, at very shallow depth, is indicated by sharp edges
to the anomalies. It is likely they represent zones in the granite bedrock
enriched in either ilmenite or haematite, both iron rich minerals which
have been recorded in the ruby bearing concentrates.
The ruby grades recorded from past drilling and trenching in the overlying
gravels are plotted on the accompanying figure, and, in general, show
an increase in grade of the rubies over the anomalies. Whether the ruby
enriching the overlying gravels originates in the rocks producing these
magnetic anomalies will be determined by pitting.

Commissioning
of new Ruby plant commences
The
Company is pleased to report that commissioning of the upgraded ruby processing
plant on the Gloucester Ruby Project commenced yesterday, and is proceeding
in a satisfactory manner.
Gravel from the Upper Terrace has been exposed in the first cut of the
mine, located one hundred metres east of Trench 11, and a working face
of between one and two metres of gravel beneath a metre and a half of
silty overburden is now being extracted.
Results from the first washing of the gravel are expected by the end of
next week.

Ruby
pit ground magnetic survey
A ground magnetic
survey to assist mine planning for the ruby mining pit and surrounding
area commences today.
The survey maps the intensity of the earths magnetic field, which
becomes stronger where deeper parts of the gravels contain high concentrations
of the iron bearing mineral ilmenite, and possibly similar concentrations
of rubies. It will attempt to determine the location and direction of
these deeper parts of the channel beneath the flats of the Upper Terrace
to allow orientation of the working face in the most efficient direction
for mining.
As well as covering the proposed pit area, the survey will extend across
previously drilled parts of the Upper Terrace, so that its effectiveness
can be checked. Several additional lines are planned across the total
width of the Upper Terrace to investigate the technique as a regional
exploration tool for mapping the extent of the ruby bearing gravels.
The upgrade of the production plant to 150 tonnes per day by installation
of additional jigs, and stripping of the pit overburden ready for mining
will be completed by the middle of this month. Mining and commissioning
of the plant will then commence.

Resources Pacific NL has entered into an agreement with Consolidated Press
Holdings Limited ("CPH") for the development of the Gloucester
Ruby Project.
The objective of this agreement is to conduct a staged development program
of the Project in which Cluff benefits from the advantage of CPHs
active involvement. CPH brings financial strength, commercial prowess
and access to its extensive media network as distinct advantages in the
future development of a market for this unique Australian gemstone.
The agreement covers three phases. Phase 1 will consist of trial mining,
Phase 2 involves the preparation of a feasibility study, and Phase 3 will
be the production period.
The principal elements of the agreement are as follows:
- Cluff will mine and exclusively sell to CPH the gemstone product from
the Project. The gemstone sale price will be set to cover mining costs
plus a margin of 10%. The definition of mining costs extends in later
phases to accommodate anticipated development costs.
- CPH will receive, as a royalty, 10% of the gemstones recovered from
mining operations on CPH freehold land. The cost of mining these stones
will be incorporated in the sale price calculation of the remaining 90%
of production.
- CPH will market the gemstones. This will involve precision cutting,
colour sorting, manufacturing fine jewellery products, promotion and,
initially, test marketing in various prestigious international centres.
Cluff is not required to contribute funds to assist CPH in developing
markets.
- Cluff will receive 20% of the net proceeds of the marketing of stones
purchased by CPH. Gemstones larger than 4 carats rough will be separately
accounted, and for these Cluff will receive 50% of the net proceeds.
The three phases of the development program are distinct, and progression
to later phases is at CPHs option. Cluff has been granted the right
to continue mining, with a 10% royalty payable in rough gemstones if CPH
does not wish to continue participation.
Phase 1 will consist of the trial mining of ten thousand tonnes of gravels
from the rich Upper Terrace at a rate of 150 tonnes per day utilising
the small plant currently on site, and is expected to yield about 120,000
carats of rough ruby. Coloured gemstone marketing is a highly specialised
business, and external expert services will be required. Natural faceted
higher-quality gemstones will initially be sold into the top level of
the wholesale and retail markets, whilst markets for the lower grade materials
will be investigated and the overall profitability of the operations determined.
The stone will be marketed by CPH with a budget in the order of one million
dollars.
In Phase 2, CPH will
prepare (at its cost, to be amortised against the project if it proceeds
to Phase 3) a detailed Feasibility Study for CPHs marketing and
Cluffs mining operations. Cluff will cooperate with the preparation
of this study, which envisages a mining and processing rate of 1,500 tonnes
per day. Subject to further statutory approval, Cluff will continue trial
mining at additional target sites in the deposit, selling the gemstones
to CPH and sharing in net marketing proceeds as in Phase 1. Cluff will
continue, at its cost, with the preparation of an Environmental Impact
Statement for the larger scale mining operation.
CPH will decide within 75 days of completion of its Feasibility Study
whether to proceed with Phase 3, Full Mining Operations. If it does so,
a New Agreement will be signed, based on the above profit sharing arrangements,
and on a Business Plan set out in the Feasibility Study. Working capital
for this large scale purchasing, cutting, manufacturing and marketing
program will be provided entirely by CPH, and is expected to be several
millions of dollars. As Cluff will be mining and processing the ruby deposit,
funding for the construction of a larger plant will be required. Provision
has been made, if necessary, for a loan facility from CPH for the full
amount of the capital cost and working capital required to construct and
operate the Phase 3 mining program.
The above arrangements apply to the Gummi river catchment. Other ruby-bearing
areas within Cluffs existing tenement base at Gloucester are subject
to a right of first refusal by CPH if Cluff seeks to introduce another
participant. If this right is exercised, gemstones from these areas will
be sold to CPH under the same conditions as in the agreement, except that
Cluff will be entitled to 50% of the net proceeds from CPHs marketing
operations.
The Cluff Board welcomes the substantial input of CPH to this exciting
project, and believes that it provides many advantages for your Company.
In addition, this co-operation in mining and marketing potentially will
have positive flow-on effects for the Australian gemstone industry as
a whole.

The area to be excavated, on the Upper Terrace of ruby-bearing gravels,
was trenched during 2002 yielding grades of 15 to 25 carats of rough ruby
per tonne.
The company has been upgrading its trommel and jig plant and camp facilities
in anticipation of the approval, and plans to commence the program shortly,
following the completion of current negotiations with Consolidated Press
Holdings Limited.
Results
of the program will be reported on a regular basis.

Chairman's
address to Shareholders: Annual General Meeting 30th May 2003
I must first
express my pleasure in participating in the direction of your Company.
Your board is looking forward to a hopefully progressive period of development
and growth.
It is appropriate that I express the Company's thanks to Walter Penninger,
the previous Company Chairman, for his work and commitment over the past
years. He has provided guidance through difficult stock market conditions
and has been instrumental in establishing the base from which the Company
can now proceed.
The Company plans to remain focused on exploring and (more importantly)
developing gemstone properties, with the objective of transforming Cluff
into a steady-state and profitable producer.
The Company has interests in three groups of properties, containing recognised
diamond, ruby and sapphire deposits. Your board plans to progress these
deposits in a systematic manner, progressively gaining market recognition
for the gemstone products and expanding production rates correspondingly.
In doing this, your board will work towards maintaining an appropriate
balance between risk and reward. As the transition between explorer, developer
and miner progresses, so too will this balance change. There are significantly
different risk profiles associated with:
* the discoveryof a gemstone-bearing deposit;
* the delineation of the mineral resource;
* the projection of future revenue, capital cost and operating cost in
the bringing of a property to production;
* the establishment of gemstone markets; and
* the assessment of value-adding opportunities such as downstream processing
and strategic partnerships.
We believe that it is important that the company recognises in a timely
manner the inherent elements of the various risk-reward profiles, and
manages them well.

Ruby
negotiations with Consolidated Press Holdings Ltd
The Company is pleased
to report that in is in negotiations with Consolidated Press Holdings
Ltd with respect to developing a ruby mining industry at its Gloucester
Ruby Project, north of Sydney.
Discussions over the last couple of months to develop the ruby project
have reached an advanced stage. The Company hopes that an agreement on
the project can be settled next week.
The discussions provide for Cluff to carry out mining on the deposit,
initially at a rate of 150 tonnes per day, yielding about 10,000 carats
of rough ruby per week. Ruby production from the mine will be purchased
by Consolidated Press Holdings Ltd.
The economics of mining determined from this operation will then be evaluated
with a view to substantially raising the throughput and profitability
of the mine.

Sale
of Monte Christo Rough Diamonds
The Company is pleased
to announce the sale of the 1,352 carat parcel of rough diamonds produced
from the Monte Christo mine at Bingara. The sale raised $A95,600, representing
a price of $US42.45 per carat.
This Monte Christo parcel averaged seven stones to the carat, with 76%
of the stone being melee (less than 0.25 carats in size) or smaller. This
is a much smaller stone size than other deposits on the field. Mount Ross
averages four stones to the carat or better, and Collas Hill three to
the carat. Larger stones fetch substantially higher prices.
The party purchasing the parcel has also shown interest in participating
in further developments on the field.
The sale is consistent with the Board's policy of generating cash flow
by sale of stock to fund further production.

Ruby
& Sapphire Marketing at Tucson Gem Fair USA
Six days
were recently spent exhibiting the Company's rubies and sapphires at the
Tucson Gem Fair, USA, by the Company's Marketing Director and Managing
Director. Tucson is the largest gem exhibition in the world, and the Company
exhibited with its US agent Manning International, at the American Gem
Traders Association, the chief gem-wholesaling group in the US.
Rubies and pink sapphire had been cut with the highest quality 58 facet
cutting, in calibrated sizes from 1 to 1.5mm. These stones were flawless,
not heat treated, and included the full range of colours available in
the deposit. About 30% of the deposit consists of stones of this quality.
They, together with the rough stone from which they were cut, were examined
by about a dozen of the US's largest gem wholesalers, andpurchasers for
manufacturing jewellers, many based in New York. All agreed that they
were of very high quality, with the deeper red colours being in unique
and beautiful shades. Many expressed an interest to purchase stones when
commercially available, despite being advised that they would be selling
in the uppermost part of the market.
Larger
rubies with commercial quality cut were also shown, with similar favourable
response.
The Company's
cut sapphires were exhibited, and are regarded by these dealers as of
commercial quality, with most suitable for large runs of commercial jewellery.
Sales of about $US 8,000, mainly as samples, were made at the Fair. Negotiations
to purchase part of the Company's large parcel of cut sapphire at bulk
wholesale prices through our agent were initiated.
