Precious metals streaming company Wheaton Precious Metals expects production growth in 2026, forecasting attributable output of 860 000 oz to 940 000 oz of gold equivalent as new streams and ramping assets boost its portfolio. The outlook represents a significant increase from 2025's 689 864 gold-equivalent ounces (GEO) and is expected to be driven primarily by an expanded streaming agreement at the Antamina mine, which will begin contributing additional production from April 1.
