Orion Mine Finance Group is looking to sell a portfolio of 87 mining royalty, streaming and off-take agreements spread across 16 countries, Reuters reported Jan. 31, citing Douglas Silver, a portfolio manager at the company.

The portfolio includes 71 royalties, eight streaming deals and eight off-take agreements on gold, silver, base metals and diamond assets in North America, South America, Australasia and elsewhere.

Silver declined to give a sales price for the portfolio, but, according to unnamed sources, the said divestment could fetch up to US$1 billion.

The U.S. private equity company is in talks with Franco-Nevada Corp., Silver Wheaton Corp. and Royal Gold Inc. for the proposed sale, which was launched in early January, according to the sources.

Meanwhile, Sandstorm Gold Ltd., Osisko Gold Royalties Ltd. and the new mining financing firm launched by former Barrick Gold Corp. CFO Shaun Usmar, Triple Flag, are also in the race for the Orion assets, Reuters said.

Alternatively, Orion is also considering an IPO of the portfolio, the newswire added.
