(06-11-2025) During the first nine months of 2025, the Caylloma polymetallic mine (Arequipa) produced 717,226 ounces of silver with an average head grade of 65 g/t, representing a 23.6% decrease compared to the same period in 2024.
Caylloma is one of three mines owned by Fortuna Mining Corp. (NYSE: FSM; TSX: FVI), Vancouver, a precious-metals mining company with operations in Argentina, Côte d’Ivoire, Mexico, Peru, and Senegal.
Lead and zinc production for the period reached 26.3 million pounds and 38.6 million pounds, respectively, reflecting a 13.6% decrease in lead and a slight increase in zinc. The average head grade for lead was 3.15% Pb, down 14.5%, while zinc head grade averaged 4.63% Zn, remaining at the same level as the previous period.
Cash cost per silver-equivalent ounce sold in Q3 2025 was US$15.19, compared to US$13.45 in the same period of 2024. The higher cost per ounce during the quarter was mainly due to lower silver production and the impact of higher realized silver prices in calculating silver-equivalent ounces sold.
The all-in sustaining cost per payable silver-equivalent ounce in Q3 2025 increased 8.3% to US$21.76, compared to US$19.9 in the same period of 2024. This increase was driven by higher production costs per ounce and a lower number of silver-equivalent ounces due to rising silver prices.
