AMT uncovers porphyry prospect

Re-assaying a historical drill hole has led to the discovery of a copper-gold-molybdenum prospect at the Copper Creek project, northeast of Tuscon, Ariz.

AMT International Mining (AAI-T) reports that hole UB-4R averaged 0.59% copper between 300 and 460 ft. down-hole and 0.9 gram gold per tonne between 300 and 540 ft. As well, 80 surface samples taken within a 900-by-1,000-ft. area surrounding the hole returned anomalous values of gold, molybdenum and copper.

The prospect, dubbed Holly, occurs at the intersection of easterly and northwesterly trending structures, with mineralization associated with a porphyry system. Seven altered breccia pipes and multiple intrusives have been mapped in the area, which contains several coincident magnetic lows.

Follow-up drilling is scheduled.

AMT International is exploring Copper Creek in joint venture with the American unit of Australian-listed GTN Resources. At last report, the property hosted resources of 11.4 million tons grading 1.34% copper in several breccia pipes.
