Brien Lundin, in the May, 2015, edition of the Gold Newsletter, refreshes his buy of Excelsior Mining Corp., recently 28 cents. Mr. Lundin said buy Excelsior in September, 2014, at 28 cents, and again in March, 2015, at 25 cents. Assuming a $1,000 investment for each of the two buys, the $2,000 position is now worth $2,119. The company owns the Gunnison copper project in Arizona. It recently conducted a hydrological drilling program designed to measure how groundwater moves through the permeable rocks that form the deposit area at Gunnison. The company says it will use the data from the program to simulate in situ recovery operations. Excelsior also recently conducted 17,110 feet of drilling in 13 holes on Gunnison. Mr. Lundin says the grades were not spectacular, but he is not worried about it. He reminds his readers that Excelsior has many avenues to development at Gunnison, which remains highly scalable. He also states there are some big, smart-money investors circling Excelsior, making now as good of a time as ever to buy the stock.
