Sandstorm Gold Ltd. is a Canadian company that provides funding to mining companies in exchange for royalties, principally in the form of net smelter returns and streams. The company focuses on precious metals but did spin off Sandstorm Metals & Energy Ltd. in 2010 as a separate TSX Venture Exchange-listed company to make volumetric production payment transactions in the base metal and fossil fuel sectors, then bought it back in 2014. Sandstorm Gold graduated from the TSX Venture Exchange to the Toronto Stock Exchange and began listing shares on the New York Stock Exchange in 2012. Wikipedia
