Lawrence Roulston, in the Aug. 20, 2013, edition of Resource Opportunities, refreshes his buy of Copper Fox Metals Inc., recently 68 cents. Mr. Roulston said buy six times between Feb. 16, 2002, and April 16, 2010, at prices ranging from 12 cents to 61 cents. He said sell half on Oct. 12, 2010, at 82 cents. Assuming a $1,000 investment for each of the six buys, selling half the $6,000 investment at 82 cents would have yielded a profit of $2,291. Mr. Roulston said buy three more times between April 29, 2011, and July 25, 2013, at prices between 53 cents and $2.42. Assuming a $1,000 investment for each of the three most recent buys, and taking into account the remaining $3,000 position after the Oct. 12, 2010, sale, the $6,000 investment would now be worth $9,269. Copper Fox owns a 25-per-cent interest in the Schaft Creek copper-gold property in British Columbia. Its joint venture partner, Teck Resources, is financing the project to production, which has freed Copper Fox to shift its attention to its Arizona copper projects, Van Dyke and Sombrero Butte. Mr. Roulston says developing the Arizona projects should add value to the stock.
