TORONTO, Ontario, March 30, 2021 – Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX: TXG) reports that in 2020, total Proven & Probable gold reserves for the Company’s El Limón Guajes Complex (“ELG”) declined 15% year-over-year primarily due to depletion, with ongoing exploration success driving a 15% increase in underground reserves, and ore processed resulting in a 20% decline in open pit reserves.
Jody Kuzenko, President & CEO of Torex, stated:
“The year-over-year decline in gold reserves at the Morelos property is consistent with the mine plan that has the ELG open pits concluding at the end of 2023. The decline in reserves at Morelos is expected to reverse when the Feasibility Study for Media Luna brings Media Luna resources into reserves. That study is expected to be published in Q1 of 2022.
“In terms of this year’s update, the processing of 487,000 ounces of gold contained in ore in 2020 was partially offset by continued underground reserve growth of 53,000 ounces, after mine depletion. Reserve growth in the ELG Underground can mostly be attributed to the infill drill program adding 93,000 ounces, with the application of a lower underground cut-off grade adding 26,000 ounces. The lower cut-off grade in the open pits resulted in an additional 28,000 ounces of reserves. The lower cut-off grades reflect a reserve gold price assumption of $1,400 per ounce versus the previous assumption of $1,200 per ounce.
“The ELG Underground is expected to remain a key value driver for Torex and its shareholders over the coming years. Since the initial Sub-Sill reserve of 180,000 ounces was published in early 2018, the underground mine has delivered approximately 212,000 ounces of gold to the processing plant, with a further 413,000 ounces of reserves in place at year-end from both Sub-Sill and El Limón Deep. With a sizeable resource base outside of reserves, multi-year step-out and infill drilling programs underway, and mineralization open at depth, we remain confident in our ability to extend the life of the ELG Underground beyond the 4.5 years implied by reserves, which remains a key enabler to delivering a smooth transition from ELG to Media Luna.”
Mineral resources are classified in accordance with the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves and the 2019 CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (collectively, the “CIM Standards”).
ELG MINERAL RESERVES
Proven and Probable reserves (contained gold) declined to 1,923 thousand ounces (“Koz”) at an average grade of 2.92 grams per tonne (“g/t”) from 2,258 Koz at 3.04 g/t at the end of 2019 (Table 2).
The 15% decrease in contained gold primarily reflects mine depletion of 554 Koz at 2.94 g/t, including 487 Koz at 3.64 g/t processed, with the remainder stockpiled. The impact of processing higher than reserve grade ore in 2020 was a key contributor to the 4% decline in the average gold reserve grade year-over-year.
Ongoing success from the step-out and infill exploration programs within the ELG Underground deposits resulted in underground reserves increasing 53 Koz net of mine depletion of 86 Koz. Infill drilling resulted in growing underground gold reserves by 93 Koz. Open pit reserves declined 388 Koz, primarily reflecting approximately 400 Koz of open pit reserves processed during the year.
The gold price used to estimate year-end reserves increased to $1,400 per ounce from $1,200 per ounce in the year prior, which led to a modestly lower open pit cut-off grade for the ELG Low Grade portion of reserves (0.8 g/t Au versus 0.9 g/t prior) and lower underground cut-off grade (3.1 g/t Au versus 3.7 g/t prior). The application of lower cut-off grades resulted in 54 Koz increase in total gold reserves at an average grade of 1.3 g/t (28 Koz impact on ELG Low Grade reserves and 26 Koz impact on underground reserves). The incremental open pit reserves attributed to the lower cut-off grade will be mined, stockpiled, and processed post depletion of open pit reserves and following processing of higher-grade stockpiled material.
ELG MINERAL RESOURCES
Measured and Indicated gold resources decreased 18% to 2,480 Koz at an average grade of 3.57 g/t at year-end 2020 compared with 3,030 Koz at 3.39 g/t at the end of 2019. Ongoing exploration success within the ELG Underground (resource increased 18%) helped offset a portion of depletion, which was the key driver of the year-over-year decline in Measured and Indicated gold resources (Table 3).
Inferred gold resources increased 7% to 630 Koz at a grade of 4.08 g/t from 590 Koz at 3.79 g/t. The increase primarily reflects updates to the open pit resource model and continued exploration success within the ELG underground, with the Inferred underground resource up 16% year-over-year.
The gold price used to estimate open pit and underground Mineral resources was US$1,550 per ounce, consistent with the gold price used to estimate Mineral resources at the end of 2019.
QA/QC AND QUALIFIED PERSONS
Torex maintains an industry-standard analytical quality assurance/quality control (QA/QC) and data verification program to monitor laboratory performance and to ensure high quality assay results. Results from this program confirm reliability of the assay results. All sampling is conducted by Torex Gold with analytical work for exploration programs at ELG performed by SGS de Mexico S.A. de C.V. (“SGS”) in Durango, and by SGS in Nuevo Balsas, Mexico (each lab is independent of the Company). Gold analyses comprise fire assays with atomic absorption or gravimetric finish.
External check assays for QA/QC purposes are performed by ALS Chemex de Mexico S.A. de C.V. (independent of the Company). The analytical QA/QC program at ELG is currently overseen by Carlo Nasi, Chief Mine Geologist for Minera Media Luna, S.A. de C.V.
