Copper One has begun drilling activities at its Lone Mountain porphyry copper prospect in New Mexico.
Work at the mine is expected to help refine and increase the potential 110 to 160 million ton resource at the property.
The Lone Mountain prospect is an oxide copper blanket spread over a 1.2km x 1.8km area with a 1,000m depth under surface which caps a big tonnage porphyry copper and copper-zinc skarn system.
More than 80,000ft of drilling in 48 holes has been carried out in these shallow oxide and deeper sulphide copper facies.
Once all drill permits are in place, the company will test the total extent of the prospect's oxide mineralisation, which is amenable to low-cost solvent extraction-electrowinning processing.
