[2] Thompson Creek Metals had additional development projects, including the Berg property in British Columbia (exploration of copper, molybdenum, and silver).

[3] The deal took place because of Thompson Creek's substantial debt incurred to develop their Mount Milligan mine.

[1] 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.

[1] The estimated life of Mount Milligan Mine is approximately 24 years (which is based on spot metal prices copper and gold).

Over the life of the mine, it is estimated that it will produce an average annual of 85 million pounds of copper and 186,700 ounces of gold in 155,000 tonnes of concentrate.

[1] In 2015 through 2019, the average annual production is projected to increase at approximately 94 million pounds of copper and 285,800 ounces of gold in 165,000 tonnes of concentrate.

Thompson Creek Metals Company filed an updated NI 43-101 Technical Report for Mount Milligan Mine on January 21, 2015 that confirms these projections.

[9] In October 2010, through the Terrane acquisition, Thompson Creek Metals obtained the Mount Milligan development project and initiated construction soon after.

[1] Mount Milligan Mine reached commercial production as of February 18, 2014, which means that the mill operated at 60% planned capacity throughput for 30 days.

[1] Royal Gold has 1% net smelter return royalty held on eight of the mineral claims and one mining lease, including those which host the deposit on the Berg property.
