What Cut Silver Output in Mexico, Peru and Chile at Once?

Silver mine output experienced unexpected disruptions across Mexico, Peru, and Chile, three nations responsible for 40.9% of global supply. Production shortfalls stemmed entirely from operational and environmental factors rather than market pricing dynamics. Mexico's Terronera mine faced a 12-day community blockade deferring roughly 0.08 million ounces of production, Peru's metallic mining sector contracted 2.52% in June driven by declining zinc and mineral grades resulting in a 9.0% drop in silver, and Chile's Antofagasta lowered copper output guidance following five million cubic metres of severe snowfall. Collectively, these disruptions removed or deferred approximately 1.1 million ounces of silver production. While representing only 2.3% of the projected 46.3 million ounce deficit for 2026, the underlying structural mechanism highlights critical supply constraints. With primary silver mines accounting for just 26% of global mine supply, roughly three-quarters of silver is mined as a by-product of base metals like copper, zinc, and lead. Consequently, silver supply remains highly inelastic and unresponsive to elevated market prices. Global mine supply is projected to remain essentially flat at 844.1 million ounces in 2026 compared to 846.6 million ounces in 2025, reinforcing a supportive multi-year fundamental backdrop.
