Arturo Préstamo, Executive Chairman and Interim CEO of Santacruz, commented, "In 2023, Santacruz continued to build a mid-tier silver and base metals producer. The Company completed several mine optimization initiatives including the integration ramp that connects the Tres Amigos and Colquechaquita underground mines at Caballo Blanco in Bolivia. And in Mexico, the operational restructuring at the Zimapan mine has already resulted in cost savings."

Mr. Préstamo continued, "The Company has also made significant progress on improving its financial position, and recently announced amended terms of sale with Glencore for the Bolivian assets. This is expected to further strengthen our balance sheet by significantly reducing the value of the consideration payable that will be recorded on our balance sheet, which will be reflected in the next quarterly financial results."

2023 Annual Production Summary - By Mine

2023 vs 2022
YTD 2022, 1,646,272 tonnes of material was processed, and 18,112,725 silver equivalent ounces was produced, and in YTD 2023 1,883,446 tonnes of material was produced and 22,641,052 silver equivalent ounces was produced. While total material processed in 2023 was 14% more compared to YTD 2022, total silver equivalent ounce production was up 25%. Annual 2023 production results benefitted from a full Q1 2023 production from the Bolivian operations. Annual 2022 figures are affected by the partial quarter of Bolivian production in Q1 2022. On March 18, 2022, the Company closed the acquisition of the Bolivian assets from Glencore and the results of the operations of the Bolivian assets are included from that date.

Q4 2023 vs Q3 2023
Santacruz processed 489,417 tonnes of material in Q4 2023, a 5% increase from the previous quarter. Silver equivalent ounce production increased 2% to 5,757,229 including 1,719,738 ounces of silver, 23,777 tonnes of zinc, 3,130 tonnes of lead, and 290 tonnes of copper. While average throughputs, head grades and recoveries varied slightly across all operations, the increase in material processed at Zimapan, and increases in mineralized material purchased by San Lucas drove consistent metal production quarter-on-quarter.

2023 vs 2022
Consolidated cash cost of production per tonne of mineralized material processed was $93.10 in YTD 2023 compared to $117.99 in YTD 2022. Significant decreases in unit production costs at the Bolivian operations, a result of higher production rates and cost saving initiatives have driven the consolidated net reduction in cash costs of 21% per tonne.

Q4 2023 vs Q3 2023
Consolidated cash cost of production per tonne of mineralized material processed remained stable with a slight increased of 1%. Cash cost per tonne at San Lucas decreased 24%, which was offset by the 15% increase at all other Bolivian operations. In Mexico, cost of sales remained stable for the quarter as full production resumed at Zimapan after recovering from a two-week haulage stoppage that took place during Q3 2023.

2023 vs 2022
Cash cost per silver equivalent ounce sold was $18.96 in 2023 compared to $17.58 in 2022. This 8% increase in cash cost was due primarily to a 18% decrease in silver equivalent ounces sold, partly offset by a 5% decrease in unit operating costs. While the metal production increased 25% for the same period, silver equivalent ounces sold decreased by 18% mainly due to Bolivia's pre-acquisition inventories sold in Q2 and Q3 2022 which accounted for approximately 80% of the total decrease in silver equivalent ounces sold. The other 20% of the total decrease in silver equivalent ounces sold can be attributed to the silver equivalent conversion ratio of base metals to silver, which was higher due to the changes in realized metal prices and resulted in the additional reduction of silver equivalent ounces sold.

Q4 2023 vs Q3 2023
Consolidated results for Q4 2023 show an 18% decrease in cash costs per silver equivalent ounce sold compared to Q3 2023. This decrease is primarily a result of lower unit operating costs for San Lucas and Zimapan, and higher sales from our Bolivian mining operations. At Zimapan, the lower unit costs are a result of the operational restructuring that began in Q3 2023. Consolidated silver equivalent ounces sold held steady quarter-on-quarter.

2023 vs 2022
2023 AISC per silver equivalent ounce sold was $22.69, compared to 2022 of $20.05. This 13% increase in unit cost was due primarily to the 18% decrease in silver equivalent ounces sold (most of which was not production related and due to Bolivia's pre-acquisition inventories sold in Q2 and Q3 2022), higher sustaining general and administrative expenses, and higher capital expenditures primarily related to the integration ramp at Caballo Blanco, which was a significant capital expenditure during 2023 (and was completed in January 2024), but partly offset by 5% lower unit operating costs. 18% decrease in silver equivalents sold which is a function of realized metal prices.

Q4 2023 vs Q3 2023
Consolidated AISC per silver equivalent ounce sold decreased 18% quarter-on-quarter to $21.37, mainly a result of lower unit operating costs, partly offset by higher sustaining general and administrative expenses and higher capital expenditures mostly related to the integration ramp at Caballo Blanco.
