Torex Gold Resources Inc. (TSX: TXG) is pleased to announce results from resource expansion and exploratory drilling completed in the broader Media Luna area (“Cluster”), which extended mineralization to the south and west of the EPO deposit and identified a potential new zone of mineralization (EPO South Extension), located between the Media Luna deposit and the Media Luna West target.
Jody Kuzenko, President & CEO stated:
“A key pillar of the Torex strategy is a renewed focus on drilling and exploration, and our latest drilling results at the Media Luna Cluster reinforce our positive outlook on our ability to complement future production at Media Luna. With the construction of the project well underway, we are stepping out beyond the existing mine resource footprint on the south side of the Balsas River, testing extensions of the Media Luna and EPO deposits, conducting initial drilling at previously identified targets, and identifying new exploration targets – all with the aim of demonstrating the underlying resource potential of the Morelos Property.
“Drilling within the EPO South target has extended the mineralized footprint of the EPO deposit by approximately 250 metres to the south and approximately 150 m to the west, which bodes well for future resource growth at EPO. As detailed in Table 1, notable intersects include 9.7 m grading 11.44 grams per tonne gold equivalent (“g/t AuEq”) at 8.51 g/t gold (“Au”), 33.44 g/t silver and 1.57% copper; 17.3 m grading 7.29 g/t AuEq at 4.18 g/t Au, 25.15 g/t Ag and 1.74% Cu; and 35.6 m grading 4.10 g/t AuEq at 2.05 g/t Au, 30.33 g/t Ag and 1.05% Cu.
“In 2021, the Company completed a high-resolution magnetic geophysical survey over a portion of the property covering the Media Luna Cluster. The survey was reduced and merged with the existing broader-scale low-resolution airborne magnetic survey and known geology to yield anomalies of interest. One anomaly, the EPO South Extension, was the focus of a small follow-up drill program that validated the utility of the survey, with four of the six holes drilled within the newly identified target intersecting mineralization, including an impressive 16.5 m grading 9.63 g/t AuEq at 8.70 g/t Au, 4.27 g/t Ag and 0.54% Cu as well as 6.3 m grading 5.48 g/t AuEq at 4.00 g/t Au, 19.44 g/t Ag and 0.78% Cu.
“Overall, this drilling, in conjunction with additional drilling both north and south of the Balsas River, enhances our confidence in bolstering the economics of the Morelos Complex beyond the levels outlined in the recent Technical Report.”

1) Intersections are reported as true thickness, based on current geological understanding of the mineralization.
2) The gold equivalent grade calculation used is as follows: AuEq (g/t) = Au (g/t) + Ag (g/t) * 0.011385 + Cu (%) * 1.621237 and use the same metal prices ($1,550/oz gold, $20/oz silver, and $3.50/lb copper) and metallurgical recoveries (85% gold, 75% silver and 89% copper) used in the Mineral Resource estimate for the EPO deposit.
Details of the assay results from expansion drilling at EPO South and scout drilling at EPO South Extension can be found in Table 2 of this release.
The gold equivalent grade calculation accounts for the same metal prices ($1,550/oz gold, $20/oz silver, and $3.50/lb copper) and metallurgical recoveries (85% gold, 75% silver and 89% copper) used in the current Mineral Resource estimate for the EPO deposit, set out in the Technical Report.
EPO – INFILL AND EXPANSION DRILL PROGRAMS
In 2022, the Company is targeting 64,000 m of drilling within the Media Luna Cluster, of which 28,000 m is focused in and around the EPO deposit. Approximately half the metres to be drilled at EPO are targeting to upgrade Inferred Mineral Resources to the Indicated category (infill program) with the remainder focused on growing the overall size of the resource envelope (expansion program).
Results from the first seven holes (approximately 4,800 m including one hole completed in 2021) of the expansion program have been positive, with drilling within the EPO South target extending the mineralized footprint of the EPO deposit 250 m to the south (ML22-778A) and 150 m to the west (ML22-773).

EXPANDING THE MEDIA LUNA CLUSTER – 2021 SCOUT DRILL PROGRAM
Over the last several years, Torex has carried out early-stage exploration activities across the broader Morelos Property. As part of these efforts, the Company completed a high-resolution geophysical survey (drone magnetic and electromagnetic survey within 50 meters line spacing) across the Morelos Property, which provided greater scale and coverage as well as improved resolution. The survey was reduced and merged with the existing broader-scale low-resolution airborne magnetic survey and known geology to yield anomalies of interest.
One anomaly identified by the high-resolution magnetic survey, EPO South Extension, was the focus of a small follow-up drill program. This program validated the utility of the survey with four of the six holes drilled intersecting mineralization. The discovery of EPO South Extension is particularly encouraging given the target zone is in an area that was thought to be unmineralized, opening the possibility for similar discoveries across the broader Morelos Property.
Given the improved visibility and information provided by the high-resolution magnetic survey, the Company has decided to expand the survey across other areas of the Morelos Property to identify new potential targets and prioritize future drilling.
MORELOS PROPERTY – 2022 EXPLORATION AND DRILLING PROGRAM
Torex expects to invest approximately $39M in drilling and exploration across the broader Morelos Property (Figure 2) in 2022, including $5M of definition and grade control drilling within the current operations.
Figure 2: Broader Morelos Property – 2022 drill program primarily focused on Media Luna Cluster, ELG Underground, as well as near-mine and regional targets:
The Company’s exploration and drill program is primarily focused around upgrading and expanding Mineral Resources at Media Luna and EPO as well as continued expansion of the ELG Underground.
MEDIA LUNA REGIONAL GEOLOGY
The Media Luna deposit is hosted within the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene stocks, sills, and dykes of granodioritic to tonalitic composition. Skarn-hosted gold-silver-copper mineralization is developed within the sedimentary rocks along the contacts of intrusive rocks as well as within altered dykes of the skarn envelope. The main portion of this mineralized package dips to the southwest at approximately 30°; in the lowest part of the known mineralization, the dip steepens to approximately 60°, while the northernmost portion of the deposit dips to the north, resulting in a broad antiformal geometry of the deposit.
Mineralization at Media Luna is hosted in skarn that developed at the contact of the intrusive granodiorite and overlying sedimentary rocks. The skarn is characterized by a mineral assemblage of pyroxene, garnet, and magnetite. Metal deposition and sulfidation occurred during retrograde alteration and is associated with a mineral assemblage comprising amphibole, phlogopite, chlorite, and calcite ± quartz ± epidote as well as variable amounts of magnetite and sulfides, primarily pyrrhotite. Additional mineralization is associated with skarn developed within and along dykes and sills above the main granodiorite intrusion
Additional information on the Media Luna deposit, the Media Luna Feasibility Study and the analytical and sampling process is available in the Company’s technical report entitled the “Morelos Property, NI 43-101 Technical Report, ELG Mine Complex Life of Mine Plan and Media Luna Feasibility Study, Guerrero State, Mexico”, dated effective March 16, 2022 filed on March 31, 2022 on SEDAR at www.sedar.com and the Company’s website at www.torexgold.com.
QUALITY ASSURANCE / QUALITY CONTROL
At the Company’s Morelos Property (see description above), all the Media Luna project drill core is logged and sampled at the core facility within the project camp under the supervision of Nicolas Landon, Chief Exploration Geologist for the Media Luna Project. A geologist marks the individual samples for analysis and sample intervals, sample numbers, standards and blanks are entered into the database. The core is cut in half lengthwise using an electric core saw equipped with a diamond tipped blade. One half of the core is placed into a plastic sample bag and sealed with zip ties in preparation for shipment. The other half of the core is returned to the core box and retained for future reference in the Company core shack with the assay pulps and coarse rejects. The core samples are picked up at the project camp and delivered to Bureau Veritas (“BV”) to conduct all the analytical work.
Sample preparation is carried out by BV at its facilities in Durango, Mexico and consists of crushing a 1 kg sample to >70% passing 2 mm followed by pulverisation of 500 g to >85% passing 75 μm. Gold is analyzed at the BV facilities in Hermosillo, Mexico following internal analytical protocols (FA430) and comprises a 30g fire assay with an atomic absorption finish. Samples yielding results >10 g/t Au are re-assayed by fire assay with gravimetric finish (FA530-Au). Copper and silver analyses are completed at the BV facilities in Vancouver, Canada as part of a multi-element geochemical analysis by an aqua regia digestion with detection by ICP-ES/MS using BV internal analytical protocol AQ270. Overlimits for the multi-element package are analyzed by internal protocol AQ374. BV is independent of the Company and its Vancouver and Hermosillo facilities are ISO-17025 accredited.
Torex has a sampling and analytical Quality Assurance/Quality Control program in place that has been approved by BV and is overseen by Nicolas Landon, Chief Exploration Geologist for the Media Luna Project. The program includes 5% each of Certified Reference Materials and Blanks; blind duplicates are not included, but Torex evaluates the results of internal BV laboratory duplicates. Torex uses an independent laboratory to check selected assay samples and reference materials and has retained a consultant to audit the QAQC data for every drill campaign at Media Luna. The QA/QC procedure is described in more detail in the Technical Report filed on SEDAR.
The scientific and technical data contained in this news release pertaining to the Media Luna exploration program have been reviewed and approved by John Makin, MAIG. Mr. Makin is a member of the Australian Institute of Geoscientists (#7313), has experience relevant to the style of mineralization under consideration, and is a Consultant Geologist employed by SLR (Canada) Consulting Ltd. Mr. Makin has verified the data disclosed, including sampling, analytical, and test data underlying the drill results.
