Jay Taylor, in the May 15, 2015, edition of Gold, Energy & Tech Stocks, says buy Columbus Gold Corp., recently 44.5 cents. Mr. Taylor previously said buy four times from July 14, 2011, to July 17, 2014, at prices ranging from 26 cents to 85 cents. Assuming a $1,000 investment for each of the four buys, the $4,000 position is now worth $4,938. Columbus has a nearly 50-per-cent carried interest in the Paul Isnard project in French Guiana. Nord Gold, which is earning a 50.01-per-cent interest in the project, is carrying Columbus through to production. An updated resource report was released in April and showed 3.8 million ounces in the indicated category and 1.1 million ounces in the inferred category. The project and Nord Gold's participation are so exciting as to be "almost unheard of for a penny gold exploration company, especially in this horrible market for juniors," declares Mr. Taylor. Separately, Columbus has made a discovery in Nevada, which in Mr. Taylor's opinion "looks for the world like a new gold-silver open-pit heap-leach mine of major size in the making." He concludes that shareholders have much to look forward to with Columbus.
