Notes to Table:
1. Gold equivalent (AuEq) mineral reserves and resources take into account respective metal prices and metallurgical recoveries for gold, silver, and copper (see Table 7 and Table 8).
2. Mineral resources are reported inclusive of mineral reserves, excluding stockpiles.
3. The reader is cautioned not to misconstrue this tabulation as a mineral reserve or a mineral resource statement. Tonnes, grades, and contained metal are shown for comparison purposes only.
4. Year-end mineral reserves and resources as well as year-over-year variance subject to rounding.
Gold equivalent (“AuEq”) mineral reserves and mineral resources take into account respective metal prices and metallurgical recoveries for gold (“Au”), silver (“Ag”), and copper (“Cu”) by deposit. Metal prices used to estimate mineral reserves and mineral resources remain unchanged following an increase in metal price assumptions used for the year-end 2023 update (see Table 7 and Table 8). As part of ongoing efforts to optimize feed rates from each of the three underground deposits, a review of metal prices used to estimate mineral reserves and mineral resources will be undertaken in 2025, with the impact on production and mine life to be evaluated against the potential impact on costs and margins.
Jody Kuzenko, President & CEO of Torex, stated:
“The year-end 2024 mineral reserve estimate reflects the new base case for the Morelos Complex which, including first production from EPO in late 2026, solidifies annual payable production of at least 450,000 gold equivalent ounces (“koz AuEq”) through 2030 and a reserve life out to at least 2035. With approximately 125,000 metres of drilling planned in 2025, almost double the metres drilled in 2024, we are now focused on enhancing the base case production profile beyond 2030, extending the reserve life of the underground deposits, and further showcasing the underlying potential of the broader Morelos Property by testing several regional targets.
“At EPO, an inaugural Probable Reserve of 781 koz AuEq was declared in September 2024. An updated reserve estimate for EPO is currently being undertaken as part of the internal feasibility study. Due to drilling undertaken in 2024 north of the main EPO deposit, Inferred Resources at EPO increased 32% to 954 koz AuEq from 721 koz AuEq.
“At ELG Underground, drilling was once again successful at replacing depletion with Proven and Probable Reserves increasing 1% to 662 koz AuEq during the year, supporting a reserve life through early 2029, which assumes an average mining rate of 2,800 tonnes per day (“tpd”) through 2026 and approximately 2,000 tpd thereafter.
“At Media Luna, updated mineral reserves and mineral resources primarily reflect results of definition drilling as well as modest refinements to some stope shapes. With the completion of the Media Luna Project, step-out and infill drilling at Media Luna is set to resume in 2025, with the goal of expanding and upgrading mineral resources as well as replacing mineral reserves.
“Overall, we delivered another solid year with respect to reserve and resource additions. With a 50% increase to the drilling and exploration budget in 2025, we expect to build on the success of the last few years and continue to demonstrate the multi-decade potential of the Morelos Property.”
Detailed breakdowns of mineral reserve and mineral resource estimates can be found in Table 5 and Table 6 of this press release. The detailed breakdowns include tonnes, grade, and contained metal estimates by metal as well as notes accompanying the applicable mineral reserve and mineral resource estimates.
PROVEN & PROBABLE MINERAL RESERVES
Total Proven and Probable Reserves are estimated at 5,096 koz AuEq at an average grade of 3.92 grams per tonne (“gpt”), representing a 7% increase relative to year-end 2023 reserves of 4,771 koz AuEq at 3.95 gpt. Prior to ore processed, Proven and Probable Reserves increased 850 koz AuEq (+18%), primarily due to inaugural reserves at EPO, which were originally disclosed in September 2024. Of the Proven and Probable Reserves at year-end 2024, 63% of the AuEq estimate is attributable to Au, 30% to Cu, and the remainder to Ag.

Notes to Table:
1. AuEq mineral reserves take into account respective metal prices and metallurgical recoveries for Au, Ag, and Cu (see Table 7).
2. Ore processed (depletion) in 2024 on a AuEq basis is based on prices and recoveries used at year-end 2023.
3. Year-end mineral reserves and year-over-year variance (2024 versus 2023) subject to rounding.
During 2024, 162% of the 525 koz AuEq processed (depleted) was replaced, driven by inaugural reserves at EPO (gain of 781 koz), drilling success outside of EPO (gain of 98 koz), block model updates (decrease of 46 koz), and other changes (gain of 17 koz).
Reserves at EPO were not updated at year-end 2024. An updated reserve is expected to be completed as part of the internal feasibility study currently underway for EPO.
At Media Luna Underground, Proven and Probable Reserves declined 49 koz AuEq as a result of ore mined during the year (decrease of 29 koz) and model changes (decrease of 19 koz), which reflects modestly higher ore tonnes at modestly lower grades returned through definition drilling as well as refined stope shapes.
At ELG Underground, Proven and Probable Reserves increased 8 koz AuEq (increase of 147 koz prior to ore mined), with drilling success (gain of 98 koz), model adjustments (gain of 7 koz), and other changes including mine design improvements and model adjustments (gain of 42 koz) more than offsetting ore mined (decrease of 139 koz).
The decline in ELG Open Pits primarily reflects ore mined during the year and, to a lesser extent, fewer than predicted ore tonnes in the final benches of the El Limón open pit, which is now exhausted. The decline also reflects open pit ore stockpiled during the year.
Within surface stockpiles of 261 koz AuEq at a grade of 1.30 gpt, 29 koz AuEq at a grade of 4.16 gpt is associated with ore from Media Luna.
MEASURED & INDICATED MINERAL RESOURCES
Measured and Indicated Resources are estimated at 7,431 koz AuEq at an average grade of 5.06 gpt, representing a 5% decrease relative to the 7,828 koz AuEq at 5.00 gpt at year-end 2023. Prior to ore mined, Measured and Indicated Resources increased 217 koz AuEq (+3%). Of the Measured and Indicated Resource at year-end 2024, 63% of the AuEq estimate is attributable to Au, 30% to Cu, and the remainder to Ag.

Notes to Table:
1. AuEq mineral resources take into account respective metal prices and metallurgical recoveries for Au, Ag, and Cu (see Table 8).
2. Measured & Indicated Resources are inclusive of mineral reserves.
3. Ore mined (depletion) in 2024 on a AuEq basis is based on prices and recoveries used at year-end 2023.
4. Year-end mineral resources and year-over-year variance (2024 versus 2023) subject to rounding.
Overall, 614 koz AuEq mined during 2024 was partially offset by drilling success (gain of 388 koz), with the remaining difference driven by block model updates (decrease of 15 koz) and other changes related to losses during mining, geological reinterpretation, and block model changes (decrease of 156 koz).
At Media Luna, Measured and Indicated Resources increased 126 koz AuEq (increase of 155 koz prior to ore mined) with definition drilling being the key driver (gain of 167 koz), partially offset by ore mined (decrease of 29 koz), and block model updates (decrease of 12 koz).
At ELG Underground, Measured and Indicated Resources decreased 28 koz AuEq (increase of 111 koz prior to ore mined) driven by drilling success (gain of 198 koz), offset by ore mined (decrease of 139 koz), block model updates (decrease of 3 koz), and other changes including losses during mining and geological reinterpretation (decrease of 84 koz).
At EPO, Indicated Resources increased by 23 koz AuEq, driven by drilling success. Infill metres drilled were lower than anticipated given a slower start to the 2024 drilling season as a result of a decision to change out drilling contractors and the associated time lost with demobilization and remobilization. As part of the 2025 drilling program, an exploration tunnel is currently being advanced in order to carry out more efficient and cost-effective infill drilling at EPO. The tunnel is being driven off the South Portal Upper and will cross over the upper portion of EPO. Drilling from the exploration tunnel is expected to commence mid-year, with a portion of the results expected to be incorporated into the year-end 2025 reserve and resource update.
The decline in Measured and Indicated Resources in ELG Open Pits reflects resource depletion as well as model changes, partially as a result of concluding mining operations in the El Limón open pit following depletion of reserves.
INFERRED MINERAL RESOURCES
Total Inferred Resources are estimated at 2,243 koz AuEq at an average grade of 4.22 gpt, representing a 4% increase relative to the 2,156 koz AuEq at 4.45 gpt at year-end 2023. Of the Inferred Resource at year-end 2024, 54% of the AuEq estimate is attributable to Au, 37% to Cu, and the remainder to Ag.

2. Year-end mineral resources and year-over-year variance (2024 versus 2023) subject to rounding.
At Media Luna, Inferred Resources increased 16 koz AuEq as a result of definition drilling.
At ELG Underground, infill drilling was prioritized towards upgrading Inferred Resources to the Indicated Resources category after a change of drilling contractor resulted in a slower-than-anticipated start to the 2024 drilling season, which reduced the level of step-out drilling to grow Inferred Resources. As such, Inferred Resources decreased 136 koz AuEq, with step-out drilling partially offsetting 198 koz upgraded through infill drilling to the Measured and Indicated Resource category during the year.
At EPO, drilling primarily to the north of EPO resulted in Inferred Resources increasing 233 koz AuEq.
The decline in ELG Open Pits resources reflects model updates and changes related to limited remaining mine life of the deposits, with the remainder of Inferred Resources contained within the current pit shells.
