Manhattan resumes drilling at Tambo Grande

Manhattan Minerals (MAN-T) has launched a 50,000-metre drill program at its 75%-optioned Tambo Grande polymetallic project in northwestern Peru.

Two rigs will attempt to expand the existing gold deposit at TG-1, while two others carry out infill drilling. A fifth rig will test other targets on the property.

During the previous phase of drilling, which consisted of 102 core holes (28,000 metres), Manhattan discovered a near-surface, flat-lying oxide gold resource of 1.3 million oz., plus a silver resource of 12.4 million oz. At the same time, the underlying TG-1 massive sulphide deposit was expanded and a potentially larger, albeit lower-grade, sulphide body was discovered at the TG-3 anomaly.

The TG-1 sulphide resource is in a 125-million-tonne pyrite-dominated body. Based on a cutoff grade of 1% copper-equivalent, the expanded inferred resource now stands at 64.2 million tonnes averaging 1.7% copper and 1.4% zinc, plus 0.7 gram gold and 31 grams silver per tonne. The preliminary stripping ratio is 1-to-1.

The sulphides are being subjected to metallurgical tests at the labs of Lakefield Research in Ontario.

A resource calculation for the TG-3 polymetallic massive sulphide deposit is being prepared.
