Guanajuato Silver Files Technical Report for Bolanitos Mine

Guanajuato Silver filed an NI 43-101 technical report for its 100%‑owned Bolañitos mine (effective March 19, 2026; reserves effective Dec 31, 2025) detailing updated mineral reserves and resources. Proven + Probable reserves total 388.7 kt containing ~908,800 oz Ag, ~14,700 oz Au and ~2.23M oz AgEq. Measured & Indicated resources amount to ~983 kt (≈3.33M oz Ag, 73k oz Au, 9.84M oz AgEq) with Inferred ~1.02 Mt (≈4.13M oz Ag, 67k oz Au, 10.19M oz AgEq). Cut‑off and reserve calculations use assumptions of $30/oz silver and $2,550/oz gold, metallurgical recoveries ~85.3% (Ag) and 90.1% (Au), and dilution/loss factors. The filing provides greater disclosure on asset quality and scale, which may support sentiment toward silver miners and long‑term silver supply dynamics, but is a company‑specific technical update rather than an immediate silver‑price catalyst.
