Castle Minerals confirms gold and zinc at Bundi prospect

THE DRILL SERGEANT: Recently-conducted RC drilling by Castle Minerals (ASX: CDT) at the company’s Bundi prospect in north‐west Ghana has intersected a coherent zone of gold mineralisation over at least 1100 metres strike.

Gold intercepts (5m RC composite samples) from the RC drilling at Bundi include:

–     10 metres at 1.27 grams per tonne gold from 25 metres;

–    15m at 1.15g/t gold from 30m, including 10m at 1.61g/t gold from 35m;

–    10m at 1.12g/t gold from 40m; and

–    20m at 1.13g/t gold from 50m, including 10m at 1.92g/t gold from 60m.

Castle said the gold mineralisation occurs within a zone of sulphide alteration that has a strong correlation with elevated zinc levels with up to four per cent zinc reported from portable XRF analysis.

The company said it had also observed coarse sphalerite (zinc sulphide) in drill chips.

“We have now confirmed Bundi as a new gold discovery for the company with the associated zinc mineralisation an unexpected bonus,” Castle Minerals managing director Mike Ivey said in the company’s announcement to the Australian Securities Exchange.

“Zinc mineralisation is rare in West Africa however Blackthorn Resources are developing their high-grade Perkoa zinc deposit in Burkina Faso that has a Probable Ore Reserve of 6.3 million tonnes at 13.9 per cent zinc.

“Bundi will now be explored for base metal mineralisation as part of our ongoing gold exploration program.”

Castle describes Bundi to be a grassroots gold discovery in a previously unexplored area.

The company indicated upcoming work programs for Bundi include individual metre analysis of gold samples, laboratory analysis of zinc zones reported from the portable XRF analysis, RAB and RC drilling and airborne geophysical surveys.
