Castle Minerals defines high-grade gold horizon at Bundi

/in /by

THE DRILL SERGEANT: Castle Minerals (ASX: CDT) has completed analysis of individual metre intervals of RC drilling at the company’s Bundi prospect, which has defined a high-grade gold and zinc horizon.

Castle said the horizon runs for over at least 1100 metres of strike, which it considers upgrades the resource potential of the Bundi prospect.

“This is a very positive outcome for Bundi, the horizon identified may represent the distal portion of a VMS (volcanogenic massive sulphide) horizon and provides considerable scope for the definition of a high-grade gold and or zinc deposit,” Castle Minerals managing director Mike Ivey said in the company’s announcement to the Australian Securities Exchange.

Bundi is part of Castle’s 100 per cent-owned Wa project in north‐west Ghana.

Intercepts from the recent drilling on the gold/zinc horizon at Bundi include;

–    2 metres at 7.87 grams per tonne gold and 0.15 per cent zinc from 40 metres;

–     3m at 6.01g/t gold and 1.04 per cent zinc from 40m;

–     3m at 3.19g/t gold and 1.2 per cent zinc from 25m; and

–    2m at 9.11g/t gold and 1.36 per cent zinc from 68m.

Castle indicated observations it had made from the mineralisation intersected to date to include:

Host rock is a quartz‐sericite schist (metamorphosed felsic volcanic?) within a sequence of Birimian metasediments;

Linear, continuous vertically dipping zone that may represent the distal portion of a volcanogenic massive sulphide horizon;

Sulphide assemblage is represented by fine to coarse grained disseminated and banded pyrite‐pyrrhotite‐sphalerite. Pyrrhotite is magnetic providing a useful exploration targeting tool;

Strong gold zinc correlation. Low in copper and arsenic; and

The mineralisation may represent a new style of gold/zinc sulphide deposit for the Birimian of West Africa.

Castle is now planning geophysical surveys to test for the occurrence of massive sulphides and extensions to the gold mineralisation at Bundi.

RAB drilling is still ongoing in the area and results will be reported upon receipt.
