Hole 4 intersected 53 metres grading 3.57% copper and 0.25% zinc, plus 7.72 grams silver and 0.52 gram gold per tonne, at a down-hole depth of 317 metres. Included was a 32-metre-wide interval of 5.18% copper, 0.22% zinc, 10 grams silver and 0.74 gram gold.
After crossing a 9-metre-thick diorite dyke, the hole cut 10.8 metres of massive sulphides grading 5.3% copper, 0.07% zinc, 9.16 grams silver and 2.32 grams gold.
The mineralization in hole 4 is 100 metres southeast of, and 150 metres vertically above, the massive sulphide and stringer mineralization in hole 3.
Both holes targeted borehole geophysical anomalies.
Hole 3 cut 18.7 metres (16.6 metres true width) of up to 90% pyrrhotite and 10% chalcopyrite, within which were 1.07% copper and 0.04% zinc. The hole was followed by 7.4 metres of stringer sulphides composed of chalcopyrite and sphalerite, which graded 1.8% copper and 0.7% zinc. In addition, the full 26-metre interval graded 1.6 grams silver and 0.3 gram gold per tonne.
An earlier hole cut 2.72% copper over 5.8 metres, including 4.17% copper over 3.4 metres.
Geophysics indicates four sub-vertical, stacked conductors. These could represent one zone, which was later offset by diorite dykes.
Hole 5 was targeted to intersect the uppermost anomaly at a vertical depth of 200 metres. The hole cut strong chloritic alteration and minor stringer sulphides at this depth, and is still in progress.
Two drills are testing geophysical targets.
Between 1989 and 1992, the West Ansil mine produced 1.6 million tonnes grading 7% copper, 4% zinc, 2 grams gold and 26 grams silver per tonne.
