Spanish Mountain–Wheaton $55M royalty: project economics and schedule for mine planners

30 Second Briefing
Spanish Mountain Gold has agreed a US$55 million royalty financing with Wheaton Precious Metals, granting a 1.5% net smelter return on all gold and silver from the Spanish Mountain project in British Columbia’s Cariboo District. Payments are staged as US$22.5 million in the coming weeks, US$12.5 million after 60,000 metres of drilling, and US$20 million once key construction and operating approvals are secured. The funding is structured to carry the project through feasibility, targeted within 18 months, towards a potential construction decision in 2028.
Technical Brief
- Staged payments explicitly link funding to drilling progress (60,000 m) and regulatory approvals, de-risking early capex exposure.
- Structure effectively front-loads exploration and feasibility expenditure while deferring the largest tranche to permitting success.
- Deal signals continued capital availability for large undeveloped Canadian gold deposits, despite permitting and cost headwinds.
Our Take
The staged payment structure tied to 60,000 metres of drilling and key approvals effectively externalises some project‑execution risk from Wheaton to Spanish Mountain Gold, a pattern also evident in Wheaton’s recent copper and silver streams where milestone‑based tranches are used to manage permitting and development uncertainty.
