Five mines started production in 2020 to bring the total number of operating assets in the Triple Flag portfolio to 15.

Nevada Copper's Pumpkin Hollow copper mine in Nevada was also restarted in August, while Stornoway Diamonds recommenced operations at the Renard diamond mine in Quebec in October.

Excelsior Mining Corp produced the first copper cathodes at the new Gunnison ISR operation in Arizona, which culminated in the sale of 90,000lb of copper at the end of January 2021.

Triple Flag's full-year 2020 revenue totalled $112.6 million, up 90% yoy, on 49% higher output of 63,059oz gold-equivalent.

Net income rose to $55.6 million, up from a year-earlier loss of $13.8 million.

Quarterly free cash flow more than tripled yoy to $30.7 million and jumped 115% to $84.4 million for the full year.

Triple Flag founder and CEO Shaun Usmar is confident the company can keep up the pace of growth.

"With [Steppe Gold's] ATO having achieved commercial production in Q2 2020, we expect the continued ramp-up of four of the new operations and Royal Bafokeng Platinum's Styldrift mine, along with a full year of gold and silver deliveries from Northparkes, in 2021," he said.

Triple Flag also received $78 million from Continental Gold's Buritica gold stream buyback in the December quarter. It retains open-ended silver stream exposure to the mine.

Triple Flag has 41 nine streams and 32 royalties. Of the 63Moz sold in 2020, gold accounted for 38,548oz and silver 22,947oz, and diamonds from the Renard mine accounted for 1,564ct.

It recently signed an agreement to acquire a portfolio of up to 39 exploration and development-stage royalties from IAMGOLD valued at up to $47.6 million.
