Jay Taylor, in the July 16, 2015, edition of Gold, Energy & Tech Stocks, refreshes his buy of Columbus Gold Corp., recently 39 cents. Mr. Taylor said buy five times from July 14, 2011, to May 15, 2015, at prices ranging from 26 cents to 85 cents. Assuming a $1,000 investment for each of the five buys, the $5,000 position is now worth $5,204. Columbus holds a 49.99-per-cent interest in the Montagne d'Or gold project in French Guiana. Mining major Nord Gold is moving the project toward production as part of its earn-in requirements, and according to the companies' just-released preliminary economic assessment (PEA), they can look forward to an after-tax net present value of $324-million (U.S.) and an after-tax internal rate of return of 23 per cent. Peter Ball, Columbus's senior vice-president, sent Mr. Taylor an e-mail talking up the PEA's results and emphasizing that the cost and resource estimates should be refined through a drill program this year. All in all, says Mr. Taylor, Columbus is in a "wonderful position."
