Chunya Project Potential Resource
CHUNYA PROJECT POTENTIAL RESOURCE ANNOUNCEMENT
12 December 2008
Shanta Gold is pleased to announce that resource 3D block modelling
and calculation has defined a total resource of 716000 ounces (at a
0.5 g/t cutoff) on the Saza prospecting licence in Chunya in
Tanzania. A final JORC compliant resource sign-off is expected in the
1st quarter of 2009 on completion of an independent inspection of the
core and review of the sampling and QA/QC protocols by the company's
resource consultants, Geologix. The non-compliant resources reported
here have been defined by reverse circulation ("RC") and diamond
drilling beneath earlier positive exploration results, historical
workings and trenching channel results. Down dip and along strike
extensions to these resources and new targets remain untested and
additional trenching and drilling is expected to increase this
resource.
Chunya Project Potential Resource Estimate
RC and diamond drilling on the Saza licence (7.83km2 in extent)
that commenced in the 4th quarter of 2007 was completed during the
second quarter of 2008.
The drilling comprised a total of 32 RC drill holes completed
during the Phase 1 drilling programme (2,979 metres), and 47 RC
(4,783 metres) and 14 diamond (1,917 metres) drill holes during the
Phase 2 drilling programme. Drilling targeted soil geochemistry
anomalies, geological mapping targets and rock chip sampling of
artisanal and historical mining excavations. Details of the drill
results have previously been released in announcements dated 18
December 2007 and 25 September 2008.
The drill holes and trenches exposed and intersected wide zones
(up to 25 metres) of mineralization, shearing and alteration. A
selection of the best drilling results is presented below for each
prospect.
The geological features commonly associated with the geological
processes that result in gold mineralization have been identified at
Saza. These include multiple phases of quartz veining, prominent
brittle-ductile shear zones, cross cutting relationships between
structures and lithological boundaries and retrograde alteration
mineral assemblages including the minerals chlorite, sericite and
muscovite. The intersection grades reported are associated with these
coincident geological features that are extensively present on the
PL. Drilling and trenching has been conducted on five prospects,
Bauhinia Creek, Black Tree Hill, Elizabeth Hill, Jamhuri and Luika
Mine.
The total potential resource comprises 13.8 million tonnes
containing 716,000 ounces of gold at 1.61 g/t (using a 0.5g/t
cut-off).
The exploration activities planned for 2009 will include
further testing of the extensions to known mineralization, testing of
newly identified mineralized zones and preliminary feasibility
investigations with a view to determining the economics of a small
scale mining operation at Luika Mine, and in the future, a larger
operation exploiting the combined economic resources of all the
prospects, all of which are within 6 kilometres of one another.
The preliminary feasibility study activities will include
completion of the JORC compliant resource modelling, metallurgical
test work and conceptual mine design and financial modelling.
Luika Mine
Drilling targeted the down dip extension of mineralization
mined in historical surface open pit and underground operations.
Luika Mine returned best RC drilling results of 9 metres at
3.95 g/t, 5 metres at 3.71 g/t, 4 metres at 5.71 g/t, 15 metres at
3.12 g/t, 7 metres at 3.51 g/t and 3 metres at 16.5 g/t. Diamond
drilling results achieved at Luika Mine include 11.44m at 7.1g/t, 3m
at 9.11g/t and 2.86m at 6.43g/t.
The Luika Mine indicated resource consists of 760,000 tonnes
containing 69,600 ounces of gold at 2.85 g/t and inferred resource of
722,000 tonnes containing 89,900 ounces at 3.87 g/t.
Although the Luika Mine target appears to be truncated by
faulting in a north-easterly direction, drill hole evidence suggests
that mineralisation is open at depth and to the southwest and it is
planned to test the extensions by trenching and possibly drilling
during 2009.
The Board has agreed to conduct a preliminary feasibility into
opening a small scale mine on this property to determine the economic
potential of this resource. The purchase of second hand gravity
concentration equipment located in the area is being considered.
Elizabeth Hill
Elizabeth Hill returned best drilling results of 7 metres at
2.75 g/t and 8 metres at 2.08 g/t.
The drill holes beneath the good trench sampling results at
surface, did not return the expected good results. Despite
intersecting appreciable thicknesses of mineralised, sheared, and
altered material, strong geological indicators of mineralization, the
grades were lower than expected. It is suspected that the gold in the
Elizabeth Hill shear zone, hosted in brecciated and undeformed white
quartz veins and foliated and mylonitised grey to blue quartz veins,
is nuggety and dominated by coarse gold. Both these factors may
present a problem to achieving representative assay results. To
further test this and improve the accuracy of the gold assay
determination, larger samples of the vein material are to be
submitted to the laboratories for assay determination.
The Elizabeth Hill indicated resource consists of 1.5 million
tonnes containing 55,600 ounces of gold at 1.16 g/t and inferred
resource of 3.5 million tonnes containing 107,300 ounces at 0.95 g/t.
Subsequent investigations at Elizabeth Hill has resulted in the
discovery of a second zone of shearing, quartz veining and gold
mineralisation (visible gold panned from crushed grab samples)
located approximately 100m-150m to the north of the drill-tested
area. This zone is obscured by slope scree and currently is being
exposed and tested by means of trenching and channel sampling.
Both target areas at Elizabeth Hill remain open at depth and to
the west.
The 2009 work programme will investigate the nugget effect in
completed drill holes, test the Elizabeth Hill extensions and the
resource will be incorporated in the preliminary feasibility study of
the Chunya project.
Bauhinia Creek
Bauhinia Creek returned best RC drilling results of 9 metres at
5.62 g/t, 9 metres at 9.21 g/t, and 10 metres at 4.16 g/t.
The Bauhinia Creek indicated resource consists of 474,000
tonnes containing 56,100 ounces of gold at 3.68 g/t and inferred
resource of 463,000 tonnes containing 29,900 ounces at 2.01 g/t.
Mineralisation along strike is displaced by later faulting, but
remains open at depth.
Fault-displaced strike extensions will be investigated by means
of exploration trenches during the 2009 work programme.
Black Tree Hill
Black Tree Hill returned best RC drilling results of 5 metres
at 8.52 g/t, 9 metres at 3.41 g/t, 5 metres at 4.1 g/t, 7 metres at
2.09 g/t, 4 metres at 2.83 g/t and 4 metres at 2.64 g/t.
The Black Tree Hill indicated resource consists of 902,000
tonnes containing 45,000 ounces of gold at 1.55 g/t and inferred
resource of 1.3 million tonnes containing 51,400 ounces at 1.23 g/t.
The target remains open at depth and to the west
During the first half of 2009, additional trenches will be
excavated to the west of Black Tree Hill to delineate and expose the
total strike extent of mineralisation.
Jamhuri Creek
Jamhuri Creek returned best drilling results of 6 metres at
5.04 g/t, 14 metres at 4.58 g/t and 3 metres at 3.22 g/t.
The Jamhuri Creek indicated resource consists of 1.4 million
tonnes containing 69,200 ounces of gold at 1.48 g/t and inferred
resource of 2.7 million tonnes containing 141,600 ounces at 1.61 g/t.
Soil geochemistry data suggests that mineralisation at Jamhuri
Creek may persist for an additional 1km in a south-easterly
direction. This is currently being tested by means of wide-spaced
trenching. The Company has already successfully identified an
extension to the mineralised shear zone at Jamhuri Creek with the
first two trenches completed. The trenching will continue into the
early part of the 2009 program and the results will determine whether
further work including drilling will be conducted.
* All intersection widths listed are down-hole intersection widths.
As completion of an independent inspection of the core and review of
the sampling and QA/QC protocols by the company's resource
consultants is only expected to be completed during 1st quarter 2009,
resources in this announcement are not currently compliant with an
internationally acceptable standard. The company intends to release a
JORC-compliant mineral resource statement in the first quarter of
2009 once an independent consultant has verified the above estimate.
The company will be testing the potential extensions to the
mineralized zones through the 2009 work programme and in line with
the strategy to develop alternative sources of exploration finance
through cash flow from production, will be conducting preliminary
feasibility work on selected ore bodies (initially the Luika
prospect) that have the potential to be brought into production with
a low capital investment.
