Canadian junior American Pacific Mining (CSE: USGD; US-OTC: USGDF) and joint-venture partner Rio Tinto (NYSE: RIO; BHP: RIO; ASX: RIO) are rapidly delineating a new resource estimate for the Madison copper-gold project in Montana, CEO Warwick Smith tells The Northern Miner. This year marks Rio Tinto's third drill campaign at the project. "Recent results have returned incredibly high-grade gold and copper, which is spreading along a good-sized area," Smith says in a recent interview. "They're really focused on that skarn at the surface, which excites us. Their drilling has made it larger, both laterally and at depth. And that's the intention this year - to follow up on some of those targets, to increase it in size."
