Extensive regional sampling
results at Cobar merit follow up, including selected drilling campaign on gold
and base metals anomalies
JUNE 2007 EXPLORATION UPDATE
Robust Resources Limited (ASX code: ROL)
("Robust") today announced update details of the extensive programs
it has undertaken since its successful listing in February on its tenements in
the Lachlan Fold Belt of NSW.
HIGHLIGHTS:
Cobar tenements:
- Extensive
maglag (1500 samples) and rock chip sampling
(237 samples) program on its three EL's at
Cobar.
- 70% analysed and 10% of these are anomalous in gold and/or
base metals and/or indicator elements warranting follow up prospecting and
selected drilling.
(Maglag samples comprise the magnetic
fraction of soils collected by hand using a high intensity magnet. It is a cost
effective and efficient method of sampling large regional areas.)
Voluntary area reduction on licence
areas following extensive regional review
- Robust
has made area reductions of around 50% in five of its ELs
delivering a sharper focus to its exploration program
PROGRAM DETAILS
Tighter focus of areas
A voluntary area reduction of about 50% has been made with
the application for licence renewals on five of the Robust areas. These reductions were made following extensive
regional sampling and data reviews. Areas of perceived higher prospectivity have been retained.
Areas relinquished were mainly covered by deep alluvium,
underlain in part by magnetic palaeochannels.
Magnetic lineaments, and areas to be relinquished, were outlined by Mr Jacob Rebek - a highly
respected former CRAE Chief Geologist - who has extensive experience in
the region. These tenements are:
- Tindarey, Mt Barrow, and Pooraka, near Cobar
- Cumnock, near Orange,
- Bauloora near Cootamundra.
One area - Glencoe - near Cowal
has been relinquished.
Expenditure on licence renewals is
$573,000
Cobar EL's
From January 2007 active reconnaissance exploration
continued on Robust's three Cobar EL's.
DPI and other data on earlier activity were reviewed, aeromagnetic data were
reprocessed, and access agreements signed. Prospective Cobar-style magnetic
lineaments were outlined and prospected using a comprehensive program of
surface maglag and rock chip sampling-virtually
completed.
Some 1500 maglag and 237 rock chip
samples have been collected from the three EL's and analysed
for gold, selected base metals (copper, lead, zinc) and indicator elements. To
date 70% of samples have been analysed, and of these
about10% are anomalous in gold, and/or base metals, and/or indicators,
including combinations.
The above work, has outlined a
number of target areas:
EL 6415-Tindarey (325 maglag and 29 rock chip samples). Of interest
are the Mt Mererre and Golconda gold fields,
four magnetic thumb prints in the east and south, and one magnetic hill in the
west, near Darling Downs station. The Golconda field (1896-1905)
- resides in a 50 to 200m wide brecciated/ silicified/ chloritised shear
zone with diggings over 400m. Grades ranged from 4 to 9.5g/t gold. Mt Mererre consisted of high grade pods associated with quartz
veins. The Lone Hand mine is also of interest; in 1918 the Mines Inspector
noted a crosscut at 30m depth assaying 3.8g/t gold. Based on data and analysis,
viable drill targets should be outlined in these fields in the next three to
six months.
EL 6413-Pooraka (531 maglag and 184 rock chip samples). The
southern boundary of this EL lies on strike with the old Mt Boppy
Gold Mine (500,000 oz gold produced). Two long maglag-rock
chip sample lines run by Robust in this area have yielded anomalous gold values
warranting follow up prospecting, including bedrock sampling by shallow
drilling.
In the remainder of the EL, based on detailed analysis of
earlier exploration, plus recent mapping/ sampling, contract geologist Nick Swingler (former CRAE), has concluded that despite
considerable past work the potential for buried gold has not been adequately
tested. Further, the Florida Trig/ Chert Ridge/ North Pole base metal prospective zone in the
centre of the EL needs to be carefully mapped and sampled at 25 x 100m centres to delineate drill targets, and a large magnetic
anomaly to the east filtered to delineate targets for sampling, and possible
drilling.
EL 6416-Mt Barrow (644 maglag and 24 rock chip samples). The
southeastern part of this EL hosts a patch of old gold and
copper-lead-zinc-silver diggings about a possible volcanic centre. These
include the Glengarry Gossan (drilled in 1976), and
the Herald, New Era and Victory gold mines. Sampling and prospecting by Robust
Resources is being completed with no results yet to hand. Other targets for
sampling have been the Box Tank and related diggings in the northwest and the Rankins Show-Bradburys diggings
in the central part. These are in addition to magnetic lineaments, mentioned
above. To date some 9% of samples analysed are
anomalous and require following up.
Of particular interest was a recently discovered
malachite-clay copper gossan located in an earth dam
2.5km SSE of Hermitage Plains station. The discovery lies proximal to the
prospective Gilmore Suture (fault zone) and on strike with and between the Babinda copper-lead-zinc mines to the southeast and the
Boundary Fence mine to the north.
This discovery will be a drilling target in the next two
months.
