Jody Kuzenko, President & CEO of Torex, stated:
"A key strategic focus for Torex is to grow reserves and resources and our 2023 drilling program was very successful in this regard. The results delivered in 2023 continue to bolster confidence that we will achieve our goal to maintain annual AuEq production of more than 450,000 ounces ("oz") beyond 2027 and extend the overall life of our Morelos assets well beyond 2033.
"At ELG Underground, Proven and Probable reserves increased to 654 koz AuEq, which now sees us with a reserve life out to late 2028. Measured and Indicated resources expanded by 432 koz AuEq (570 koz AuEq prior to mined depletion), while Inferred resources increased by 119 koz AuEq. Resource growth was a direct result of successful drilling as well as the assumption of a lower cut-off grade, reflecting higher metal price assumptions and lower costs due to steady increases in underground mining rates.
"At EPO, infill drilling was successful in upgrading Inferred resources, while step-out drilling expanded the overall mineralized footprint. Indicated resources increased by 481 koz AuEq to 1,153 koz at year end, surpassing even our aggressive target of one million AuEq ounces. The updated resource will form the basis of an internal prefeasibility study to be completed in the second half of 2024.
"Our strategy to grow reserves and resources has been supported with meaningful investment, with an average of

During 2023,
The decline in ELG Open Pits primarily reflects depletion (389 koz AuEq) partially offset by optimizations carried out to the block model during 2023.
At ELG Underground, Proven and Probable reserves increased 146 koz AuEq net of depletion of 134 koz AuEq (280 koz prior to depletion), with 129 koz added through drilling, 86 koz added via a lower cut-off grade (reflecting higher metal prices and lower unit costs), and 65 koz added through block model optimizations.
At Media Luna, Proven and Probable reserves primarily reflect changes to Measured and Indicated resources delivered during 2022 as these results were not available to be incorporated into the year-end 2022 update. Modestly higher tonnes at modestly lower Au, Ag, and Cu grades reflect the conversion of Probable reserves to the Proven category (following resources upgraded to the Measured category during 2022), refinements to the block model carried out during 2023, and the benefit of additional Probable reserves (reflecting resources upgraded to the Indicated category during 2022). The impact of these changes on a AuEq basis was offset by the higher relative contribution of Cu and Ag on AuEq reserves given higher metal prices used for Cu (+
Metal prices used in the estimation of mineral reserves have increased relative to year-end 2022. Higher metallurgical recoveries for ELG Underground reflect the increased proportion of reserves to be processed through the upgraded processing plant starting in late 2024 relative to the proportion anticipated at year-end 2022, including improved Cu and Ag recoveries due to the installation of copper and iron sulfide flotation circuits as part of the Media Luna Project.

The impact of updated AuEq formulas on AuEq values (incorporating higher metal prices and updated metallurgical recoveries) on Proven and Probable reserves is negligible when comparing year-end Au, Ag, and Cu reserves assuming the AuEq formulas used at year-end 2022.
