___________________________________________________________________
Pilbara explorer, Warwick
Resources Limited (ASX:WRK) today announced a spectacular gold intersection
from its maiden 1,254m drilling programme on the Jimblebar and Copper Range
projects.
Warwick Resources
Technical Director Bruce McQuitty said the drilling results provided a solid
start for Warwick’s
shareholders following its listing on the ASX in February.
“Our maiden drilling
program has demonstrated the presence of high grade gold mineralisation at
Jimblebar while delivering some very encouraging copper intersections on the Copper Range
project,” Mr McQuitty said.
The gold intercept was 1m @ 160g/t Au within 8m @ 22.3g/t Au from 34m depth in drill
hole WRKRC6. Copper results showed broad copper intersections with high
grade intervals at Copper Knob, 67m @ 0.48%
Cu from surface including 6m @
2.19% Cu from 6m depth in drill hole WRKRC2.
“We always believed
the Jimblebar goldfield was under-explored and under-exploited.
Historical mining activities in the 1930’s stopped when the old timers
hit the water table and so we identified the potential to discover high grade
gold shoots at shallow depths.
“We are well funded
and have access to drill rigs to undertake the next drilling programme which
will include new and step-out targets following on the successes of the first
programme,” he said.
“The
Pilbara region is host to world class iron ore deposits and more recently
emerging as a gold and base metals province. Warwick Resources has
assembled the people and projects to become an emerging explorer in the
Pilbara,” Mr McQuitty said.
Jimblebar
Gold Project (100% owned by WRK)
Three drill holes were
completed at Sunny South (WRKRC5-7) and one at Middle Watch (WRKRC8), located
midway between the Sunny South and Shearers workings (see figure 2 for locations).
Sunny South
Drilling at Sunny South
returned significant gold intersections which are listed in Table 1.

Note: All intersections
calculated using a lower cut-off of 1.0g/t Au. Gold was analysed by 40g Fire
Assay with ICP MS finish.
WRKRC5 stepped out 30m
from a previous high grade intersection of 2m
@ 25.1g/t Au in drill hole SP9. A 1m
interval of 3.1g/t Au was
intersected from 45m depth and occurred within a broad zone of disseminated
pyrite from 31m to 100m. WRKRC6 infilled a 30m gap in the previous
drilling. The drill hole intersected 8m of
22.3g/t Au from 34m depth, including 2m @ 85.3g/t Au. The intersection is 20m along strike from a
similar intersection of 7m @ 26.6g/t Au
from 32m depth in drill hole SP3, drilled by a previous explorer. WRKRC7
drilled beneath the main shaft at Sunny South and returned intersections of 3m @ 3.1g/t Au from 17m and 10m @ 2.1g/t Au from 27m.
In all three holes at
Sunny South, the gold mineralization is associated with a
chlorite-quartz-magnetite unit, within a broader halo of disseminated pyrite
mineralisation. The mineralised unit dips to the east at about 70 degrees.
These results have
confirmed the presence of substantial high grade gold shoots within the broader
mineralised structure. The drilling indicates the mineralisation is open both
to the north and south and down dip to the east. Warwick intends to step out the drilling
pattern to locate additional high grade shoots and will conduct some first pass
metallurgical tests on the drill samples.
Molybdenum

Significant levels of
molybdenum (Mo) were present in all four drill holes at Jimblebar (Table 2).

At Middle Watch prospect
(Figure 2), drill hole WRKRC8 returned an intersection of 91m @ 0.02% Mo from surface, including a 1m interval of 0.09% Mo. WRKRC8 drilled
beneath an outcrop of gossanous, quartz veined banded iron formation from which
rock chip values up to 0.17% Mo
have previously been reported (March quarterly report, April 2007). The
intersection in WRKRC8 is significant in that it is presently unconstrained and
could be marginal to a larger deposit. The Company intends to undertake further
surface sampling, mapping and interpretation to scope out the size of the
Jimblebar molybdenum discovery and understand its geological context.
Copper Range (100% owned by WRK)
Based on past exploration,
Copper Range has the potential to be a very
large tonnage low grade copper project. Warwick
also intends to locate satellite sources of higher grade copper along the 9km
strike length of the Copper
Range unit. Located
within this unit are the recognised prospects Copper Knob, Copper Knob East,
Alteration Hill and Copper Hill (Figure 1).
Copper Knob
Four holes were drilled at
Copper Knob with the aim of confirming copper intersections obtained by
previous explorers, evaluating potential base metal and precious metal credits,
obtaining information on the oxide and primary mineralisation zones and testing
the footwall position of the Copper
Range unit. All
four drill holes recorded significant copper intersections, as listed in Table
3.

Intersections calculated
using 0.15% Cu cut-off except where indicated and maximum internal waste
interval (<0.15% Cu) of 4m. NSR = no significant result.
WRKRC1 & 2 were
drilled close to the summit of Copper Knob where oxidation is more extensive
and may have contributed to copper enrichment. WRKRC3 and WRKRC4 were drilled
near the base of Copper Knob and intersected less oxidised material.
WRKRC1 was designed to
twin an early percussion drill hole CRP09, which was one of 18 percussion holes
drilled by Endeavour Oil in 1972 to test the oxide zone. CRP09 was drilled to a
maximum depth of 45.72m (150 feet) and averaged 0.20% Cu over the entire hole.
By comparison, the first 46m of WRKRC1 averaged 0.36% Cu. The 80% higher result in WRKRC1 could be due to a
number of factors, including local geological variations, better sample
recoveries or improved assaying techniques. The result is regarded as a
positive in that it implies that the early drilling may have understated the
copper grades, however more holes need to be twinned to confirm the pattern.
The results of WRKRC3 and
WRKRC4, which were collared close to the hangingwall of the Copper Range unit,
show that copper grades tend to be highest about 20-40m below the hangingwall,
then taper off gradually towards the footwall. None of the drill holes reached
the footwall of the Copper
Range unit, although
WRKRC1 was drilled to maximum depth 148m for this purpose. Copper grades in
excess of 1.0% Cu were recorded in
all drill holes. Generally, there is a good correlation between copper and
gold. The maximum assay of 5.44% Cu
and the maximum gold assay of 0.5g/t Au
came from the same interval: 9-10m in WRKRC2.
A suite of 21 elements were
assayed in addition to copper, to assess the potential for credits. The results
show that cobalt, zinc, gold and palladium are potentially important credits.
Further work will now be undertaken to assess their value impact on the
project. The company also intends to undertake another phase of drilling
at Copper Knob to scope the size of the oxide and primary mineral zones before
committing to resource drilling.

Intersections calculated
using 0.15% Cu cut-off except where indicated. NSR = no significant result
WRKRC9 and WRKRC10
targeted copper mineralization at Copper Hill. The holes were drilled 80m apart
and underpinned two holes drilled by a previous explorer, one of which, JRC030,
had returned a significant intercept of 9m at
1.2% Cu, 0.15g/t Au, 12g/t Ag, 0.12%Zn and 0.17% Ni from 22m depth, within the oxide zone. However WRKRC
9 & 10 failed to locate the same tenor of mineralisation, despite WRKRC10
intersecting a 14m interval from 68m depth averaging 18% pyrite. Structural
complications due to faulting may have offset the mineralisation. The company
will undertake detailed mapping to resolve the structural complexity before
undertaking further drilling at Copper Hill.
WRKRC11 was drilled about
1.6km south of Copper Hill and targeted copper mineralization evident in
outcropping magnetite lenses near the hangingwall of the Copper Range
unit. An intersection of 4m @ 1.1% Cu
and 0.09g/t Au was obtained from
9m depth, including 1m @ 2.7% Cu, 0.17g/t Au
from 10m. The result confirms that the magnetite lenses, which occur
along much of the 9km strike of the Copper
Range unit, represent an
important target for copper-gold mineralisation.
WRKRC12 drilled beneath
old workings near Alteration Hill from which an anomalous lead rock chip sample
of 0.43% Pb was obtained. Only slightly anomalous lead was recorded in the
drill hole however some significant copper results were obtained from 89-91m
depth.
The results of the
drilling between Copper Hill and Alteration Hill highlight the importance of
magnetite lenses within the as Copper Range unit as a host for base metal-gold
mineralisation. The company is currently mapping these lenses and evaluating
previous EM geophysical anomalies to assist with planning the next phase of
drilling. The copper intersections and copper credit results from the
drilling at Copper
Range confirm the
company’s strategy to evaluate the project in terms of a large tonnage
low grade open cut project at Copper Knob, with multiple satellite sources of
higher grade ore.
Update
on other Projects
The Company is continuing
the exploration of its other projects and will provide an exploration update in
due course.
