John Kaiser, writing in a Jan. 17, 2017, SVH Tracker, refreshes his buy of Inzinc Mining Ltd. at 22 cents. The editor has a long history with the stock. He said buy three times between Nov. 3, 2003, and April 2, 2008, at prices ranging from 18 cents to 28 cents. On Nov. 17, 2008, he said sell at six cents. Assuming investments of $1,000 for each of the three buys, selling at six cents would have yielded a $2,236 loss. He said buy the stock three more times through April 13, 2010, at prices ranging from six cents to 24 cents, and then said sell on Jan. 2, 2012, at nine cents. Assuming $1,000 investments for each of the three buys, selling at nine cents would have resulted in a $150 loss. Mr. Kaiser then said buy the stock back immediately at nine cents, and buy five more times through Oct. 18, 2016, at prices ranging from eight cents to 15 cents. An investment of $1,000 for each of those six buys would now be worth $13,444. Mr. Kaiser says the company's West Desert zinc project in Utah is worth developing at current zinc prices. Some investors believe that rises in the zinc price rise will be crushed by new supply from China, but Mr. Kaiser points out that Chinese zinc supply comes from dozens of small mines. Many of these Chinese zinc mines, he notes, are big polluters and are approaching the ends of their lives, which could be accelerated. China, he says, is waking up to its pollution problem, specifically to water pollution which has worked its way into the food supply.
