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 3 and Table 5).
2. Mineral Resources are reported inclusive of Mineral Reserves.
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. Metals prices used to estimate Mineral Reserves and Mineral Resources remain unchanged.

Jody Kuzenko, President & CEO of Torex, stated:

“We are pleased with the results of the year-end 2022 Mineral Reserve & Resource estimate which further highlights the geological excellence of our Morelos Property. On a total asset AuEq basis, net of depletion, Measured & Indicated Resources increased 567 koz (+8%) and Inferred Resources increased 41 koz (+2%). Prior to mine depletion of 511 koz AuEq, Measured & Indicated Resources increased 1,078 koz (+16%).

“At Media Luna, an inaugural Measured Resource of 473 koz AuEq at an average grade of 8.06 grams per tonne (“gpt”) AuEq was declared. The Measured Resource is contained within three separate zones of the deposit. Additionally, drilling was successful in expanding Inferred Resources along the northern and southern boundaries of the Media Luna deposit while inclusion of outstanding results from the 2021 infill drilling program resulted in additional Indicated Resources.

“The success at Media Luna was equally matched by the success at EPO, with infill drilling delivering an inaugural Indicated Resource of 671 koz AuEq at an average grade of 5.16 gpt AuEq. Step-out drilling to the south and west of EPO was successful in partially offsetting resources upgraded to the Inferred category. Based on the updated resource estimate and potential for additional resource growth, we are growing increasingly confident about the prospect of EPO becoming an additional future source of mill feed at the Morelos Complex, thereby even further unlocking the economics of the Media Luna project.

“At the ELG Mine Complex, conversion of resources to reserves, drilling success and model updates resulted in more than 60% of Proven & Probable gold reserves processed in 2022 being replaced. On an AuEq basis, additional laybacks in the El Limón open pit added approximately 190 koz to Mineral Reserves while expansion of the El Limón Sur open pit added approximately 50 koz. Reserve gains in the producing Sub-Sill and ELD deposits as well as initial reserves within the Sub-Sill South and El Limón Sur Deep deposits offset a majority of ore mined from the ELG Underground in 2022.”

Detailed breakdowns of Mineral Reserve and Mineral Resource estimates can be found in Table 7 and Table 8 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 Resource estimates.

PROVEN & PROBABLE MINERAL RESERVES

Total Proven and Probable Mineral Reserves are estimated at 4,947 koz AuEq at an average grade of 3.98 gpt AuEq, representing a 3% decrease relative to year-end 2021 reserves of 5,123 koz AuEq at 3.90 gpt AuEq. Of the Proven & Probable Reserves, 73% of the AuEq estimate is attributable to Au, 23% to Cu, and 4% to Ag.

Notes to Table:

1. Gold equivalent Mineral Resources take into account respective metal prices and metallurgical recoveries for gold, silver, and copper (see Table 5).
2. Measured & Indicated Resources inclusive of Mineral Reserves.
3. Ore mined (depletion) in 2022 on a AuEq basis assumes respective based on prices and recoveries used at year-end 2021.
4. Year-end Mineral Resources and year-over-year variance (2022 versus 2021) subject to rounding.

The decline in Measured & Indicated Resources within the ELG Open Pit primarily reflects depletion. At the ELG Underground, infill drilling was successful in more than offsetting 110 koz AuEq of mine depletion.

Measured & Indicated Resources specific to Media Luna increased 275 koz AuEq, driven by the benefit of incorporating outstanding assay results from the 2021 infill drilling program, results which were received post the cut-off date for the year-end 2021 resource estimate. Additionally, infill drilling targeting three separate zones within the Media Luna deposit resulted in an inaugural Measured Resource of 473 koz AuEq at an average grade of 8.06 gpt AuEq.

Infill drilling at EPO was successful in establishing an inaugural Indicated Resource of 671 koz AuEq at an average grade of 5.16 gpt AuEq. The higher-grade nature of the Indicated Resource relative to the previous Inferred Resource at EPO is due to higher grades encountered through the 2022 infill drilling program, which in the area targeted led to a conversion rate of 108% based on AuEq contained metal and 83% based on tonnes.

At Media Luna, drilling targeting spatial gaps in prior drilling was successful at adding Inferred Resources along the northern and southern boundaries of the deposit. The success of this program partially offset resources upgraded to the Indicated category.

Drilling at the El Limón Sur open pit was successful in expanding Inferred Mineral Resources within the upper areas of the deposit while drilling within the ELG Underground added to Inferred Resources. The additional Inferred Resources helped offset a portion of resources upgraded to the Indicated category during 2022.

Step-out drilling to the south and west of EPO offset a portion of the Inferred Resources upgraded to the Indicated category (671 koz AuEq). The EPO deposit remains open to the north, south and west.
