The Horizon Copper transaction involves Royal Gold acquiring all issued share capital for cash at C$2 ($1.46) per share, indicating an 85% premium over the 20-day VWAP and a 72% premium on the closing price as of 4 July 2025, with a transaction equity value of approximately $196m.
Royal Gold president and CEO Bill Heissenbuttel said: “Royal Gold has a 40+ year history of consistently executing a strategy of disciplined growth in gold, and the addition of the Sandstorm and Horizon assets will create a global portfolio of precious metals interests that is unmatched in terms of asset diversification, development and organic growth potential, and exploration optionality.”
The acquisitions are expected to add 40 new producing assets to Royal Gold’s portfolio, which will contribute between 65,000 and 80,000 gold equivalent ounces (GEOs) in 2025, increasing GEO production by roughly 26%.
The pro forma revenue mix is projected to be 87% from precious metals, with gold accounting for approximately 75% of total revenue.
The combined company will boast a diversified portfolio with 80 revenue-producing assets, and no single asset is expected to account for more than 13% of net asset value (NAV).
The pro forma portfolio will also include 47 development assets, such as Platreef, MARA, and Hod Maden, and a further 266 assets in the evaluation and exploration stages.
The transactions are expected to close in the fourth quarter of 2025. Both transactions will require approval from shareholders and the Supreme Court of British Columbia, with additional regulatory clearances or approvals.
