JIMBLEBAR
GOLD - DRILLING AND EXPLORATION UPDATE
KEY POINTS
• Aircore
drilling, rock chip and soil sampling results outline new gold targets
• RC
drilling programme commences
• Further
soil sampling and Gradient Array IP surveys in progress
Diversified Pilbara explorer Warwick
Resources Limited (ASX:WRK) has commenced an RC drilling programme on the Company’s
100% owned Jimblebar gold project near Newman, following further encouraging
exploration results.
Warwick Resources Managing Director Bruce McQuitty said recent aircore drilling, rock
chip sampling and soil sampling programmes have identified seven promising new
gold targets which will be the subject of further investigation.
“These results represent
further exploration progress for Warwick Resources, and vindicates the
extensive exploration programme we have in place across the historic Jimblebar
region,” Mr McQuitty said.
The Company is
targeting predominantly open pit gold resources at Jimblebar, initially focusing
on the Sunny South Prospect where shallow high grade intersections have been
identified. The current RC drilling programme will also target the previously
mined Shearer’s prospect for the first time.
A total of 111 aircore drill holes,
110 soil samples and 108 rock chip samples tested a 5km strike length of the
Jimblebar mineralised trend on 100m to 400m spaced traverses in order to
identify geochemical anomalies for subsequent drill targeting (see Figure 1). Aircore
drilling was used to obtain samples of weathered bedrock in areas of
transported cover, soil sampling was employed in areas with limited amounts of
outcrop and rock chip samples were taken in areas where soils were absent, such
as on the Jimblebar range of hills.
Highlights of the geochemical
sampling programme include:
- Two
large gold anomalies (>25ppb Au) and two subordinate anomalies with soil
results to 816ppb Au to the south of Sunny South have defined a new target
zone 1km in length which remains open to the east (see Figure 1).
- A 700m
long gold anomaly centered on the Shearers workings includes three rock
chip values above 1g/t Au, with a maximum value of 2.39g/t Au.
- Large
gold anomalies are associated with the Middle Watch (max 834ppb Au in soils),
Pilliwinkle (max 269ppb Au from aircore) and Sunny South prospects (max
807ppb Au from aircore), the latter two are open to the east.
- Strongly
anomalous gold and base metals from the Koondra prospect (max 732ppm Au in
soils, 2.3% Pb, 0.27% Cu, 0.11% Zn from rock chips), which remains open to
the south.
- A new
target, 600m to the north of Koondra, with maximum values from aircore
drilling of 97ppb Au and 4,550ppm tungsten.
The anomalies to the south of Sunny
South and to the north of Koondra represent promising new targets. A further
phase of aircore drilling is required to obtain a better understanding of the
extent of the anomalies before they are subject to RC drilling. This next phase
of work is scheduled for February.
The current RC drilling programme will
be directed at the Sunny South and Shearers prospects which lie 1km apart
within the 2km long historical Jimblebar goldfield.
Warwick Resources’ recent
drilling at Sunny South has demonstrated the presence of high gold grades at
shallow depths and a mineralised strike length of 600m, open to the north and
south. In June, Warwick Resources announced a gold intercept from
Sunny South of 1m @ 144g/t Au within 8m @ 20.4g/t Au from 34m depth.
The geometry of the mineralised
lodes in the vicinity of the historical workings at Sunny South has been
reinterpreted by Warwick Resources’ geologists to consist of three
stacked lodes, each dipping at about 40 degrees to the east. Further to the
south a single lode has been identified, extending over a strike length of
400m. The current drilling programme is designed to test the new
interpretation.
This programme will also be the
first time that Warwick has drilled the Shearers lode, where sporadic shallow
drilling by previous explorers returned best intersections of 1m @ 5.4g/t Au,
3m @ 3.1g/t Au and 15m @ 0.6g/t Au. Small-scale mining of the Shearers lode in
the early 1930’s produced 1,792 oz Au from 6,100t of ore at an average
grade of 9.1g/t.
Results from drilling are expected from
late January.
A further programme of soil sampling
and a Gradient Array Induced Polarisation (IP) survey are in progress at
Jimblebar. The Gradient Array IP is considered to be an effective technique for
locating disseminated sulphides which form a halo to gold mineralisation at
Jimblebar. Results from the survey are also expected from late January.
