Bolivian Operations General Overview
Production at the Bolivian operations has been steady over the past two quarters, with production flexibility at each operation contributing to consistent output. The San Lucas ore sourcing and trading business continues to perform well and provides feed for each of the process plants at Bolivar, Porco, and the Don Diego plant, which processed Caballo Blanco feed. This third-party feed source allows each plant to operate efficiently and provides additional ore for blending, as necessary.

Bolivar Mine
First quarter 2023 production included material from the newly developed Rosario section, which help offset delays in mining the Central section. These delays were caused by the extension of services for pumping and ventilation as this section descends. Rosario stopes were larger and contained higher grade silver than expected, which offset lower grade toll feeds from San Lucas Ore sourcing and trading business. Zinc and lead production were lower than expected, but silver production was great than anticipated.

Porco Mine
Production was down slightly, and metal grades were lower than expected because of operational challenges. Equipment downtime in the trackless Hundumiento zone and stope sequencing had an impact on timing of higher-grade ore feed, which also affected metal recoveries. This was partially offset by toll feed tonnage from the San Lucas ore sourcing and trading business being greater and higher grade than anticipated, which resulted in total metal production for the quarter being higher than anticipated.

Caballo Blanco Group of Mines
Production and total development metres was as expected for this group of mines (Colquechaquita, Tres Amigos and Reserva mines). At the Don Diego milling facility, the toll feed from San Lucas ore sourcing and trading business was lower grade than anticipated, but in the first quarter of 2023, this was offset by mined grades.

Zimapan Mine (Mexico)
Two separate mines (Monte and Carrizal mines) are linked by a trackless haulage drift leading to the process plant. Production from the complex is stable at current tonnage and grade with improvements to the metal output largely driven by metallurgical performance. Issues in the first quarter of 2023 with process water shortages resulting from a regional drought provided opportunities for planned plant maintenance but have also impacted total tonnes processed. The flexible mine plan allows production from different zones based on metal values and blending requirements. During the first quarter of 2023 the Zimapan complex experienced a considerable increase in copper recoveries.
