High Grade Iron Oxide Copper-Gold Mineralisation at Broken Hill

  • Work commences at Copper Blow Project - an iron oxide copper-gold (IOCG) zone with high grade mineralisation

  • 11.8 metres at 6.7% copper, 1.92 g/t gold and 13.7 g/t silver

  • 19.8 metres at 1.8% copper, including 3 metres at 4.6% copper

  • 15 metres at 2.7% copper, 0.53 g/t gold and 3.7 g/t silver

  • 2.1 metres at 3.2% copper, 0.65 g/t gold, 5 g/t silver and 0.038% cobalt

  • IOCG with strong similarities to deposits in Mt Isa region

  • Significant untested potential for cobalt, rare earth elements and molybdenum

  • Abundant untested targets for sulphide mineralisation

Silver City Minerals Limited (ASX: SCI) (“Silver City” or “the Company”) is pleased to announce that it has begun work on the high grade Copper Blow copper-gold project at Broken Hill. Copper and gold occur in magnetite and quartz-rich lodes. Historic geochemical and mineralographic data suggest additional potential for associated cobalt, molybdenum and rare earth elements.

The Copper Blow project is located approximately 20 kilometres to the south of Broken Hill (Figure 1). It lies within an existing Silver City Minerals exploration licence (EL 8255) and is part of a joint venture arrangement between SCI (75%) and CBH Resources Ltd (CBH, 25%). CBH owns and operates the Rasp Mine (lead-zinc-silver) and associated mill and sulphide froth floatation plant at Broken Hill. Copper Blow has come to the attention of SCI as part of a review of deposit styles and existing drill hole data in the Broken Hill district.

Historic reports describe Copper Blow as being epigenetic, discordant to host rock structure, associated with magnetite and enriched in copper and gold. In this respect it is markedly different from the lead-zinc-silver lodes deposited at Broken Hill.

Old workings and drill holes have established a 1 kilometre long zone of copper mineralisation, open along strike, with high grade targets for immediate drill testing. This zone lies in the southern part of a linear magnetic anomaly hosting copper and iron mineralisation which extends for over 4 kilometres within joint venture tenure.

Background

SCI compiled the historic drill hole data for Copper Blow in order to build a 3D geological model. During the course of this compilation it became apparent that a number of very high grade intersections were located in drill core from exploration dating back to early 1980s.

Hole DDHCB009 was of particular interest as it contained an intersection of 11.80 metres at 6.7% copper, 1.92 g/t gold and 14 g/t silver in a chalcopyrite-rich (copper sulphide) quartz breccia within a major shear zone (Table 1). DDHCB006 and 008 were of similar grade and overall width and suggestive of steeply dipping mineralised structures where true thicknesses of 10 to 15 metres occur. Best intersections in these holes occur between 160 to 220 metres below the surface but multiple lode zones were encountered throughout the holes and all host sulphide mineralisation. All lodes are open along strike and down dip.

These holes were not followed-up by closer spaced or step-out drilling. All subsequent exploration focussed on the delineation of near-surface open pit resources with a number of shallow reverse circulation (RC) drill programs being conducted. This style of drilling tested the project to only 100 metres vertical depth. Oxidation of sulphides extends down to approximately 50 metres below surface.

SCI concludes that there is significant scope for near-term discovery of high grade coppergold mineralisation with a minimum strike-length of 300 metres focussed on these deeper diamond drill hole intersections. Current drilling suggests mineralisation could extend to depths in excess of 250 metres below the oxidation boundary.

History

Copper Blow is an historic mine which was developed on five levels down to approximately 60 metres below surface. Records indicate that mining commenced in 1887 and up until 1937 produced 715 tonnes of copper ore (Plate 1). Reports by the Geological Survey of NSW indicate grades up to 13% copper.

Between 1949 and 1953 the Zinc Corporation drilled three diamond holes and between 1982 and 1994 a consortium of joint venture partners drilled ten diamond holes over a strike length of 900 metres. Of these six were drilled to depths of greater than 250 metres. It was this series of holes which first encountered high grade copper mineralisation.

Three campaigns of RC drilling were subsequently conducted (1997, 2003 and 2006); all focussed on shallow drilling for open pit ore. This work failed to outline significant tonnages of economic mineralisation but did serve to identify lode zones near surface. More importantly, a new zone of previously unknown copper mineralisation, close to surface and north of the higher grades in diamond holes was encountered (RC holes CBRC05 to 07; Figure 4). In total fifty three holes have been drilled at the project.

Geology

The Copper Blow lode horizon extends to over 4 kilometres in a northeast-trending zone characterised by a persistent magnetic linear feature and a series of iron-rich mine workings (Figure 2 and 3). The area of drilling and results referred to in this report is located at the south western end of this lode corridor.

Both NSW Geological Survey and structural consulting reports indicate that Copper Blow is fault and shear controlled and transects host rock stratigraphy obliquely. In this regard the mineralisation is unlike the lead-zinc-silver ore bodies at Broken Hill which are predominantly stratiform, being deposited at approximately the same time as the enclosing sediments.

The structure that hosts the copper-gold mineralisation dips steeply to the northwest, crosscuts various units of the Thackaringa Group in its northeastern part and forms a faulted boundary between the Thackaringa and Broken Hill Groups in its southwestern part. It passes through a variety of metamorphosed sandstone, siltstone and volcanic rocks. Metamorphism has transformed these into a collection of crystalline, locally banded, feldspar-quartz-mica gneiss and amphibolite. Where the mineralised shear zone occurs these become finer grained and schistose.

The mineralised part of the host shear zone is characterised by enrichment of biotite (potassium-rich mica), magnetite (magnetic iron oxide), potassium feldspar and quartz. Later sericite, chlorite and iron-rich carbonate minerals are also abundant. Copper and iron sulphides are deposited as a metasomatic replacement of magnetite or as matrix to a welldeveloped quartz breccia (Plates 2 & 3).

While the Copper Blow magnetic linear feature is over four kilometres long, copper mineralisation is known to be best developed in old workings and as outlined in drill holes in the southwestern two kilometres of the structure. It appears to be truncated by the Thackaringa-Pinnacles Schist Zone at its southern-most extremity. Structural analysis

SILVER CITY MINERALS LIMITED

undertaken in 1996 suggests highest grade copper-gold mineralisation occurs in a window 200 to 300 metres long where the shear is off-set or bent, forming a dilational jog.

Geological interpretation suggests that within this window, high grade, steeply southwest plunging shoots may occur. Due to the nature of the historic drill programs this concept has not been tested and will be the initial focus of future work by SCI (Figure 3). Additional exploration of the mineralised structure will take place along the entire 4 kilometres to assess potential for other high grade shoots. This will include testing beneath copper mineralisation encountered in RC holes CBRC05 to 07 (Figure 4, 5 and 6).

Mineralisation at Copper Blow has been described in company reports and academic literature as belonging to a class of deposits known as iron oxide copper-gold deposits

SILVER CITY MINERALS LIMITED

(IOCG). In this respect it has close affinities to mineral deposits such as Starra (Selwyn) or Ernest Henry located in the Mt Isa region of Queensland.

Other Elements of Interest (cobalt, rare earths and molybdenum)

Mineralogical reports of the copper-rich zones describe other minerals of interest such as allanite (a rare earth-rich mineral), uraninite (a uranium-rich mineral) and molybdenite (molybdenum sulphide).

In 1998 Triako Resources, re-assayed five samples from historic diamond drill holes DDHCB006 and 009 to ascertain potential for other economic elements. These were small grab samples taken from storage and no core lengths were recorded. Samples with high grade copper were clearly selected (copper range 4.13% to 6.67%). Four samples were of magnetite-hosted copper and one was quartz breccia-hosted. The report concluded that cobalt, molybdenum and zinc are elevated in the quartz breccia sample (sample no 100901 returned 4.13% Cu, 39.9 g/t Au, 1570 ppm Co, 110 ppm Mo and 1680ppm Zn). Samples of both magnetite and quartz breccia-hosted mineralisation were also enriched in rare earth elements especially cerium (1 to 256 ppm), lanthanum (0.4 to 154 ppm), neodymium (0.9 to 117 ppm) and yttrium (1.1 to 242 ppm; NSW Geological Survey Open File Report GS1998/238).

Of the 5722 drill sample analytical records that SCI has collated for this project, only 351 (6%) have cobalt analyses. Of these, those displaying anomalism (+300ppm) largely correlate with elevated iron and copper. Significant values are tabulated (Table 1) however the paucity of systematic sampling precludes full assessment of potential.

Similarly, there has been no systematic work on the evaluation of rare earth elements or molybdenum at Copper Blow. Given that IOGC deposits around the world are strongly enriched in these elements, especially cobalt, the likelihood that Copper Blow is similarly enriched is high. Part of the future exploration by SCI will assess these elements.

Aspects of the determination of mineralisation
that are Material to the Public Report.
•The determination of mineralisation in
historic reports stems solely from
analytical work on downhole samples.
The results are considered to be material
to this report in that the analyses identify
mineralisation of potentially economic
grades. It is the view of this Company
that further confirmatory work is required
in the form of drilling and high quality
analytical work.
In cases where ‘industry standard’ work has
been done this would be relatively simple (eg
‘reverse circulation drilling was used to obtain 1
m samples from which 3 kg was pulverised to
produce a 30 g charge for fire assay’). In other
cases more explanation may be required, such
as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (eg submarine nodules)
may warrant disclosure of detailed information.

If the exclusion of this information is justified
on the basis that the information is not
Material and this exclusion does not detract
from the understanding of the report, the
Competent Person should clearly explain why
this is the case.
•This information is to be included in this
public report
Data
aggregation
methods
In reporting Exploration Results, weighting
averaging techniques, maximum and/or
minimum grade truncations (eg cutting of high
grades) and cut-off grades are usually
_Material and should be stated. _
•No grade truncations were used.
•Cutoff grades using copper are indicated
Where aggregate intercepts incorporate short
lengths of high grade results and longer
lengths of low grade results, the procedure
used for such aggregation should be stated
and some typical examples of such
aggregations should be shown in detail.
•Intercepts were calculated using the
following criteria:
o
Minimum length of 1 metre,
o
Maximum of two consecutive intervals
below the cut-off grade,
o
No restriction on the number of below cut-
off intervals provided the overall interval
equalled or exceeded the cut-off grade for
the element.
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
•No metal equivalents were reported.
Relationship
between
mineralisatio
n widths and
intercept
lengths
These relationships are particularly important
in the reporting of Exploration Results.
•Sampling of diamond core was often
undertaken only where mineralisation was
logged and this should produce a direct
relationship between grade and
mineralisation.
•Percussion chip sampling however was
generally done on 1 metre or 2 metre
intervals and as such there may be some
minoroverestimationof mineralisedzones.
If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported.
•Geological interpretation suggests steep
northwest dips. Diamond drill holes of
interest were drilled from NW to SE
approximately orthogonalto dip
If it is not known and only the down hole
lengths are reported, there should be a clear
statement to this effect (eg ‘down hole length,
_true width not known’). _
•The reported intervals are down-hole lengths
and the true widths are interpreted in
section.
Diagrams Appropriate maps and sections (with scales)
and tabulations of intercepts should be
included for any significant discovery being
reported These should include, but not be
limited to a plan view of drill hole collar
locations and appropriate sectional views.
•Annexure 1
Balanced
reporting
Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and high
grades and/or widths should be practiced to
avoid misleading reporting of Exploration
Results.
•Drill hole results reported to cut off grades
and parameters specified. The purpose of
this public report is to present the highly
anomalous analytical results from previous
exploration and to note similarities between
these and existingdeposit models
Other
substantive
exploration
data
Other exploration data, if meaningful and
material, should be reported including (but not
limited to): geological observations;
geophysical survey results; geochemical
survey results; bulk samples – size and
•No other meaningful material is documented.
