Recent drilling has focused on the West massive-sulphide zone, first drilled last year. Highlights include one hole that intersected 29 metres grading 4.06% copper and 2.85% zinc, plus 126.45 grams silver and 4.13 grams gold per tonne, including 15 metres of 6.04% copper, 3.86% zinc, 173.08 grams silver and 7.41 grams gold. This intercept was drilled about 50 metres along section from holes that returned 4-5% copper.
Three other holes tested the zone successively at vertical depths of up to 850 metres below surface. One hole intersected 37.8 metres grading 1.02% copper, 5.36% zinc, 78.96 grams silver and 0.97 gram gold at a vertical depth of 550 metres. The deepest massive-sulphide intersection to date graded 0.78% copper, 3.8% zinc, 49.73 grams silver and 0.36 gram gold over 5 metres.
Two holes were drilled along strike to the south. One intersected 8.8 metres of 3.86% copper, 3.17% zinc, 86.68 grams silver and 1.96 grams gold at a vertical depth of 150 metres; the other, 9.9 metres of 3.26% copper, 4.69% zinc, 126.34 grams silver and 1.38 grams gold at a vertical depth of 200 metres.
The property is underlain by mafic and felsic volcanic rocks. The felsic rocks are intercalated with carbonate-rich exhalite lenses. The West zone has a felsic hangingwall and a mafic footwall. The mineralization displays sulphide zonation, and drilling suggests there are about 50-metre-thick boudinaged horizons of semi-massive-to-massive-sulphide layers within the felsic rock. These are locally cut by a series of diorite dykes.
A ground electromagnetic survey has identified two parallel conductors immediately south and along strike of the current drilling.
