Current Projects
The
following are current projects for the company, with other
projects under review...
Mount Sandy
Tenement
The Mount Sandy
Tenement holding consists of application M21/154 which
overlays P21/602 – 604 as per statutory conversion
regulations. The tenement has an area of 420Ha and is located
adjacent to the
Great Northern Highway
30km south of Cue. Vegetation is sparse and access is
considered very good.
The licence lies
within the Archaean Meekatharra-Wydgee greenstone belt, and
comprises a north-northeasterly trending sequence of basalt,
dolerite, tuffaceous siltstone, carbonaceous shale, chert and
banded iron-formation. Minor granitic and felsic porphry
bodies have intruded this sequence. Quartz veining and
irregular quartz blows occur.
Historically, at least
several hundred ounces of gold have been recovered from dry-
blowing and metal detecting activities. Prior to 1994, Sons of
Gwalia Ltd carried out mapping, auger soil sampling and
interpreted aeromagnetic data. Auger soil sampling to a depth
of 500mm indicated numerous zones of N – NE trending
>25ppb Au soil anomalism, the largest of these being 900m x
150m. These anomalies are adjacent to areas of prospecting and
dry blowing where cover consists of thin colluvium. Subsequent
RAB and RC drill testing of soil anomalies and old workings
returned a best intersection of 20 m @ 0.29 g/t Au from quartz
veins within schistose siltstone, basalt and dolerite. Other
RAB and RC intersections include 12m@0.39g/t, 8m@0.35g/t,
8m@0.49g/t and 4m@0.62g/t. These intersections were generally
located at less than 20m depth.
SOG’s also conducted
an aeromagnetic interpretation which outlined several major
and numerous minor fault and shears. In particular a dilatant
zone was interpreted along one of these major structures and
another was inferred. This structural interpretation does not
seen to have been used for drillhole planning criteria.
Despite completed drilling having been nowhere near
comprehensively testing all locations with a good
mineralisation potential, the ground was farmed out to Nimrod
Resources NL. Nimrod planned to include the tenement as part
of a package as the basis for a stockmarket float. This did
not go ahead at that time and the agreement lapsed without any
work being completed. Nimrod however drew some interesting
comparisons between the Mt Sandy geological setting and that
at Tuckabianna and other known mineralised areas in the same
greenstone belt.
The obvious future
strategy here would be a re-evaluation and integration of the
previous soil sampling and drilling with the aeromagnetic
information. A drilling program could then be proposed to test
areas of potential mineralisation.
Mount
McClure
Tenement
E36/389 is located
50km NE of Leinster in the eastern goldfields. The tenement
covers an area of 29 graticular blocks, being approximately
73.8km2.
The tenement lies over
part of the western contact of the Yandal Greenstone Belt.
Poorly exposed sediments and volcanics form the margin of the
belt on the eastern side of the tenement. A number of NNW
striking shears have been identified in this contact zone.
Immediately to the west of this is a zone of foliated granite
and mafic and felsic volcanic rocks. Further to the west again
lies a belt of undeformed granitoid rocks which is mostly
overlain by Quaternary sand plain and alluvial deposits. The
Mt McClure Fault lies 2km to the east of the tenement boundary
and is host to a series of gold deposits including Success,
Parmelia, Challenger and Dragon.
Audax Resources
carried out soil and lag sampling over the South part of the
tenement during 1995. Several Au soil anomalies were
delineated, the best of which persisted over 700m and which
was open to the south (Chilli anomaly). Subsequent RAB
drilling failed to locate a significantly mineralised source.
During 2003/2004
George Lee
conducted soil and stream sampling which extended the Chilli
anomaly and defined others along the E margin of the tenement.
Under a joint venture agreement, Bronzewing Gold NL acquired
aeromagnetic data and carried out an Aircore drilling program.
Interpretation of the aeromag data delineated a pattern of
cross cutting shears or faults across the central area of soil
anomalism. Drilling was frustrated by shallow depths of
weathering and holes were generally short, the deepest being
only 17m. 22 holes were drilled on 4 lines for only 189m and
tested 3 of the soil anomalies . Significant results include
4m@0.27g/t, 4m@1.1g/t and 4m@0.21g/t. All significant results
were less than 8m depth. This program did not effectively test
the soil anomalies as drillhole spacing was too wide and drill
lines were too far apart. Nevertheless, Bronzewing withdrew
from the agreement. Future work could include further soil
sampling to infill blank areas on the sampling grid as well as
more extensive RAB drill testing of the soil anomalies.
Mt Rankin
The Mt Rankin
tenements comprise Mining Leases 77/302, 77/661, 77/716,
77/1035 and application for Exploration Licence 77/1211. They
are located about 15 kilometres west south west of Southern
Cross. Access is via the
Great Eastern Highway
and then on gazetted Shire roads.
The Mt Rankin Project
is situated in the Southern Cross Province of the Archaean
Yilgarn Craton. The Project area is dominated by a prominent
Banded Iron Formation (BIF) ridge, which trends northwest
within a sequence of amphibolitic mafic and occasional
ultramafic lithologies. The Rankin and Jaguar pits are
situated in close proximity to a crosscutting northeast
–southwest fault. Previous reports suggest a close
relationship to these cross cutting faults, the BIFs and gold
mineralisation. Detailed evaluation of the aeromagnetic data
was recommended to identify further, possibly more subtle
structures.
Gold was discovered in
the area in late 19th century when a number of small
underground operations produced average grades of around 7g/t.
Modern exploration for gold as been conducted since the mid
1980s by various companies. This culminated in the 1990s with
the mining of the Mt Rankin and Jaguar open pits. Mt Rankin
had a reserve of 195,000 @ 2.55g/t and Jaguar a measured
resource of 62,450 @ 3.5g/t. There is the suggestion from
Burmine that 15,000t may remain at the base of both pits at a
grade of 2.5-3g/t. Some of the more obvious future strategies
include:
-
Detailed
evaluation of the aeromagnetic data to locate structural
targets which focus gold mineralisation.
-
Detailed
evaluation of the good regional database
-
Establish the
amount and grade of ore remaining in the Rankin and Jaguar
pits
-
Evaluate potential
for gold mineralisation at depth, especially high grade
“Golden Pig style”.
-
Evaluate parallel
BIFs for potential gold mineralisation.
Previous explorers
have recommend “drilling of the dextral fault between the
Rankin and Jaguar pits which exhibits magnetite destruction”
and “evaluation of the strongly folded BIF ridge 50-100m
north-east of Jaguar which appears to be untested and may have
potential for iron ore”.
