Including 1,671,359 ounces of silver and 25,053 tonnes of zinc

Santacruz Silver Mining Ltd. (TSX-V: SCZ)  reports its Q2 2024 production results from its Bolivar mine, Porco mine, Caballo Blanco Group of mines and the San Lucas feed sourcing business, all located in Bolivia, and the Zimapan mine located in Mexico.

Highlights:

• 1,671,359 ounces of silver;
• 25,053 tonnes of zinc;
• 2,908 tonnes of lead;
• 284 tonnes of copper;
• For silver equivalent production of 4,819,552 ounces.

Arturo Préstamo, Executive Chairman and CEO of Santacruz, commented, “Santacruz’s operations rebounded from Q1 2024, thanks to the hard work and dedication of all our teams. We processed a near record high of just over 500,000 tonnes of mineralized material. The increased production of mineralized material is primarily attributable to the new integration ramp at Caballo Blanco, which significantly enhanced the performance of this asset, and the Company anticipates that these increased mining and processing rates will continue at Caballo Blanco throughout the rest of the year.”

Production Summary – Total

Bolivar Mine

In Q2 2024, Bolivar processed 72,151 tonnes of mineralized material and produced 1,029,806 silver equivalent ounces including 427,665 ounces of silver and 5,168 tonnes of zinc. When compared to Q1 2024, material processed, and silver and zinc production were in line with the previous quarter. The Company expects Q3 2024 production to be in line with Q2 2024.

When comparing Q2 2024 to Q2 2023, mineralized material processed increased 8% because of improved mining rates that resulted from the continued benefits from the dewatering system upgrades that were implemented last year. This improved system is expected to continue delivering dry working areas for the rest of the year. Silver production was in line with Q2 2023, however zinc production experienced a 55% increase as a result of a 41% improvement in zinc head grades. In Q2 2023, water handling issues in the higher-grade Central zone caused a reduction in secondary development, which resulted in mining transitioning into lower grade zinc areas during the initial months of Q2 2023.

Porco Mine

In Q2 2024, Porco processed 51,307 tonnes of mineralized material and produced 534,300 silver equivalent ounces including 151,258 ounces of silver and 3,276 tonnes of zinc. When compared to Q1 2024, silver production decreased primarily due to the 19% decline in silver head grade, which was a result of the Company mining in lower grade silver areas while it reconfigured the mine plan to enable better productivity. This was slightly offset by a 5% increase in recovery because of the adoption of a new silver collector reagent. Zinc production remained in line with the previous quarter, and the Company expects Q3 2024 production to be in line with Q2 2024.

When comparing Q2 2024 to Q2 2023, mineralized material processed increased 11% because of higher mining rates. Despite the increase in mineralized material processed, silver equivalent ounce production decreased year-over-year as a result of lower silver head grades being mined, which is a result of the Company reconfiguring the mine plan to enable better productivity.

Caballo Blanco Group

In Q2 2024, Caballo Blanco processed 83,661 tonnes of mineralized material and produced 968,646 silver equivalent ounces including 318,520 ounces of silver and 5,331 tonnes of zinc. The 15% increase in mineralized material processed is a result of the integration ramp connecting the Colquechaquita and Tres Amigos mine being fully operational and enabling the more efficient movement of mining equipment between these two mines, and the improved transportation of mineralized material to the surface. The Company anticipates mining and processing rates to be consistent with this level for the remainder of 2024.

The 12% increase in silver production and 13% increase in zinc production are both a result of the increase in mineralized material processed as grades and recoveries were in line with the previous quarter. The Company expects Q3 2024 production to be in line with Q2 2024.

When comparing Q2 2024 to Q2 2023, Caballo Blanco processed 13% more mineralized material, also because of the completed integration ramp. The increase in mineralized material processed resulted in 11% more zinc production as grades and metallurgical recoveries were in line with the same period last year, however the average silver grade mined was 27% lower this quarter, and as a result silver production decreased 20%. The decrease in the silver grade is associated with two higher grade veins that had been mined in the first half of 2023, and since then mining has transitioned to veins with lower silver grades. For the remainder of the year, the Company anticipates mining in areas with similar silver grades mined in the first half of 2024.

San Lucas Feed Sourcing

When comparing Q1 2024 to Q2 2024, San Lucas processed 83,900 tonnes of mineralized material and produced 1,200,854 silver equivalent ounces, including 364,607 ounces of silver and 7,150 tonnes of zinc. The 21% increase in mineralized material processed is a result of the Company purchasing more feed from regional suppliers.

When comparing Q2 2024 to Q2 2023, mineralized material volumes were in line year-over-year. The fluctuation in head grades quarter-over-quarter and year-over-year is a result of San Lucas purchasing mineralized material from local suppliers. This fluctuation in head grade is expected to continue moving forward.

Zimapan Mine

In Q2 2024, Zimapan processed 209,735 tonnes of mineralized material and produced 1,085,946 silver equivalent ounces including 409,309 ounces of silver and 4,127 tonnes of zinc. When compared to the previous quarter, mineralized material processed showed a marginal improvement. Silver production also showed a marginal improvement compared with the previous quarter, while zinc production increased 13% because of better grades and recoveries when compared to Q1 2024 as more mineralized material is being sourced from Level 960 at the Carrizal mine.

When comparing Q2 2024 to Q2 2023, material processed increased 22%. During Q2 2023 the Zimapan mine experienced several logistics and transportation issues that resulted in a significant decrease in mineralized material mined and processed. Silver and zinc production increased as a result of the increase in mineralized material processed, higher grade material being processed and significantly improved metallurgical recoveries.
