Description Yes, Goldstone Resources is aware it's a metal not a stone; it just happens to like the name. The company has properties primarily in Ontario and Quebec, where it searches for precious metals. Its focus is a set of undeveloped properties in northern Ontario. The company was founded in 1945 as Bargold Mines Limited. It became Ontex Mining Limited in 1981 and Ontex Resources Limited in 1983; it then took its current name after buying Roxmark Mines in 2009. Goldstone agreed to be acquired by Premier Gold Mines Limited in a stock swap in 2011.
