Silver — Full commodity dossier

Supply structure and processing chokepoints

Primary mine production of silver is distributed across 15 tracked producer jurisdictions in the baseline model, representing a global output of 25,930 metric tons. The production base is led by Mexico, which accounts for 6,300 metric tons or 24.3 percent of world output. The top three producing jurisdictions—Mexico (24.3 percent), Peru (13.9 percent), and China (13.1 percent)—collectively govern 51.3 percent of aggregate primary extraction.

Market concentration across primary extraction scores 1,192 points on the Herfindahl-Hirschman Index (HHI), positioning primary silver mining within the unconcentrated category. On standard antitrust and procurement vulnerability thresholds, an HHI exceeding 2,500 indicates acute structural concentration, where production decisions, fiscal adjustments, or local disruptions in the leading jurisdiction directly impact global supply availability.

The geological reserve base provides visibility into medium-term supply potential: Peru holds 19.9 percent of identified reserves in sovereign reporting^[1]. The reserve concentration index scores 1,320 HHI, compared to 1,192 for operating mine output. Because reserve concentration matches or exceeds production concentration, geographic diversification of silver requires greenfield geological exploration and discovery, rather than mere capital re-allocation to known deposits.

Downstream conversion of raw ore or unrefined concentrate into refined specification product represents the principal point of commercial leverage. While mining output defines the physical volume ceiling, the chemical conversion stage—smelting, hydrometallurgical leaching, solvent extraction separation, and cathode electrowinning—is historically more concentrated than extraction itself. Commercial consumers requiring high-purity feedstocks must manage counterparty and operational exposure at the refining stage rather than at the pithead.
