The story
In 2006, the privately held Thompson Creek Metals Company (USA) was acquired by Canadian-based, publicly traded mining company Blue Pearl Mining Ltd for US$575 million, in addition to other payments worth as much as US$125 million depending on the price of molybdenum. The name Blue Pearl Mining Ltd was changed to Thompson Creek Metals Company Inc. in May 2007. From October 2006 through August 2013, Thompson Creek Metals was solely a molybdenum producer.
Pursuant to the acquisition of Terrane Metals Corp. in October 2010 for about US$700 million in a combination of cash and common stock, the company diversified its assets by adding significant reserves of copper and gold. Concurrent with the acquisition of Terrane, the Company entered into a Gold Stream Arrangement with Royal Gold Inc. as a financing mechanism for the purchase of Terrane. The Gold Stream Agreement was amended twice for a total payment by Royal Gold of approximately US$781 million for the right to purchase 52.25% of the gold from Mount Milligan Mine for US$435 per ounce for the life of the mine.
