Finally, gold-focused Rusoro Mining rounds out the list. It’s interesting that Rusoro is on the rise, since the company’s assets were nationalized by the Bolivarian Republic of Venezuela in 2012. The latest update on the situation came in June of last year, when Rusoro reported that both parties had completed their oral and written submissions in Rusoro’s arbitration before the World Bank’s International Center for Settlement of Investment Disputes.

Shares of Rusoro Mining rose 46.15 percent last week to $0.095 despite there being no new news on the matter. The company’s share price has gained 72 percent so far in 2015 and 280 percent over the past year.
