US Copper Corp. announce that it is expanding the previously announced diamond drilling program at its 100% owned Moonlight-Superior Copper Project in north-east California. The revised plan is to drill 12-15 holes instead of the initially planned seven holes. The current drill program has been progressing well, with six holes totaling 5,000 feet completed to date at the Superior deposit, one of three deposits at the Moonlight-Superior Copper Project. With the closing of the company's $2 million financing in May, the Company has determined that it can advance its plans to upgrade the Superior deposit to the indicated category with the upsized drill program.
