TORONTO, June 16, 2021 (GLOBE NEWSWIRE) — Torex Gold Resources Inc. (the “Company”) (TSX: TXG) announces an updated Mineral Resource estimate for the Media Luna project, which now consists of a gold equivalent ¹ (“AuEq”) Indicated Resource of 3.54 million ounces (“Moz”) at an average grade of 5.27 grams per tonne (“g/t”), reflecting a 58% increase in contained AuEq metal in the Indicated Resource category compared to the previously reported estimate. Of the Indicated Resource, 61% of the contained value is attributable to gold (“Au”), 31% to copper (“Cu”), and the remainder to silver (“Ag”).

The updated Inferred Resource (exclusive of Indicated) is estimated at 2.48 Moz AuEq at an average grade of 4.08 g/t AuEq.

Jody Kuzenko, President and CEO of Torex Gold, stated:

“Infill drilling at Media Luna since the start of 2020 and into the first few months of 2021 was successful in upgrading 8.3 million tonnes of Inferred Resource to the Indicated Resource category. The 2021 infill drilling program is targeting to upgrade additional resources to the Indicated category for inclusion in the upcoming Feasibility Study, which remains on track for completion in Q1 2022 and will form part of an updated Technical Report for the entire Morelos property.

“With the existing drill program covering only 30% of the area of the host magnetic anomaly, we see significant potential to grow and upgrade the resource base at Media Luna over the coming years. We are currently developing a multi-year exploration program, which will likely see us expand and extend the current infill drilling program at Media Luna through the end of 2021, restart step-out drilling at Media Luna in 2022, target further resource growth from the ELG Underground, and test other high priority targets on the Morelos property.”

The updated Mineral Resource estimate for Media Luna effective as of April 30, 2021, prepared in accordance with National Instrument (“NI”) 43-101, is reported at a AuEq cut-off grade of 2.0 g/t.

^{1)   Gold equivalent ounces defined as AuEq (Moz) = Au (Moz) + Cu (Mlb) * ($3.50 per lb Cu / $1,550 per oz Au) + Ag (Moz) * ($20 per oz Ag / $1,550 per oz Au).}

COMPARISON TO THE DECEMBER 2019 MINERAL RESOURCE ESTIMATE

The April 30, 2021 Mineral Resource estimate includes 568 core drill holes (approximately 241,800 metres), of which 137 drill holes (approximately 36,000 metres) were completed under the 2020 program and 38 drill holes (approximately 11,800 metres) from the 2021 infill campaign completed prior to the effective date of the Mineral Resource estimate. The remaining drill holes planned under the 44,000-metre infill program for 2021 (Figure 1) will be included in a subsequent resource update, which will form the basis of the Media Luna Feasibility Study.

^{Notes to Mineral Resource comparison table:
1)   The reader is cautioned not to misconstrue this table as a Mineral Resource estimate. Listed AuEq grades and tonnes are shown for comparison purposes only.
2)   Mineral Resources are reported above a 2.0 g/t gold equivalent (AuEq) cut-off grade; AuEq = Au (g/t) + Cu % * (77.16/49.83) + Ag (g/t) * (0.64/49.83).
3)  The gold ($1,550/oz), silver ($20/oz), and copper ($3.50/lb) price assumptions used in the April 30, 2021 Mineral Resource estimate are consistent with the metal price assumptions employed within the December 31, 2019 Mineral Resource estimate. Additional information on the December 31, 2019 Mineral Resource estimate, is set out in the Company’s most recent annual information form available under the Company’s profile on SEDAR at www.sedar.com and on the Company’s website ( www.torexgold.com ).
4)   Mineral Resource statement including a breakdown of contained metal and grades by gold, silver, and copper can be found in Table 2 of this press release.
5)   Mineral Resources subject to rounding.
6)   Of the total metal inventory, comprising the April 30, 2021 Mineral Resource estimate, in the Indicated Resource category 61% of the contained value is attributable to Au, 31% to Cu, and the remainder to Ag; within the Inferred Resource category, 52% of the contained value is attributable to Au, 39% to Cu, and the remainder to Ag.}

The updated Mineral Resource, with an effective date of April 30, 2021, is outlined in Table 2 of this press release. Table 3 illustrates the sensitivity of the Indicated and Inferred Resources to changes in AuEq cut-off grade.

The updated Indicated Mineral Resource for Media Luna is estimated at 3.54 Moz AuEq (20.9 million tonnes at an average grade of 5.27 g/t AuEq), a 58% increase over the December 31, 2019 Indicated Resource estimate of 2.24 Moz AuEq (12.6 million tonnes at a grade of 5.55 g/t AuEq).

The updated Inferred Resource is estimated at 2.48 Moz AuEq (18.9 million tonnes at a grade of 4.08 g/t AuEq) versus the prior estimate of 4.56 Moz AuEq (33.5 million tonnes at a grade of 4.23 g/t AuEq). The 14.6 million tonne decline reflects the 8.3 million tonnes upgraded to the Indicated category as well as the impact of a refreshed geologic model using information gathered from the tighter-spaced drilling (30 metre spacing versus 100 metre spacing) in the Media Luna Upper zone. The updated geological model indicates that the thickness of the skarn hosted mineralization is more variable within the Media Luna Upper zone than was found in the Media Luna Lower zone.

The Inferred Resource estimated for Media Luna includes 1.01 Moz AuEq (8.0 million tonnes at a grade of 3.93 g/t AuEq) from EPO, which is unchanged from the prior resource estimate. EPO is a zone of mineralization located north of the main Media Luna deposit and south of the Balsas River that contributed to the economics contained in the September 2018 Preliminary Economic Assessment. As mineralization from EPO is only in the Inferred Resource category, the zone will not form part of the mine plan within the upcoming Media Luna Feasibility Study. Based on the location to the Guajes Tunnel, EPO remains a high priority for future infill drilling.

The gold ($1,550/oz), silver ($20/oz), and copper ($3.50/lb) price assumptions used in the April 30, 2021 Mineral Resource estimate are consistent with the metal price assumptions employed within the December 31, 2019 Mineral Resource estimate for Media Luna.

MINERAL RESOURCE ESTIMATE METHODOLOGY

The Mineral Resource estimate prepared by Torex is based on data from 568 core drill holes (approximately 241,800 metres) drilled since 2012 within the Media Luna resource area. Lithological logging information as well as geochemical analyses were used to define lithological grade domains. Grades were estimated within lithological domains using hard boundaries.

Block grades within the exoskarn domain were estimated using one-metre capped composites in a three-pass interpolation plan using inverse distance cubed (ID3) weighting. A variable anisotropy was applied to ensure that searches were following the local geology. Results were evaluated onto blocks of 5.0 metres by 5.0 metres by 5.0 metres (sub-blocked to 2.5 metres by 2.5 metres by 2.5 metres) and classified as Indicated or Inferred based on drill hole spacings of 30 metres or 100 metres, respectively. Results were validated using standard validation techniques and reported above a cut-off grade of 2.0 g/t AuEq; mineral resources are generally continuous above this cut-off grade.

MEDIA LUNA 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. Endoskarn from the granodiorite intrusive also shows localized mineralization in MLU related to quartz vein systems.

Additional information on the Media Luna deposit, the updated Media Luna Preliminary Economic Assessment (PEA) and analytical and sampling process is available in the Company’s technical report (2018 Technical Report) entitled the “Morelos Property, NI 43-101 Technical Report, ELG Mine Complex, Life of Mine Plan and Media Luna Preliminary Economic Assessment, Guerrero State, Mexico”, dated effective March 31, 2018 filed on September 4, 2018 on SEDAR at www.sedar.com and the Company’s website at www.torexgold.com .

QUALITY ASSURANCE/QUALITY CONTROL

At the Company’s Morelos Gold Property, 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, and 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. BV is independent of the Company.

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 pulverization 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 30 g 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.

Torex has a sampling and analytical Quality Assurance/Quality Control (“QA/QC”) program in place that has been audited 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, however, 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 QA/QC data for every drill campaign at Media Luna. The QA/QC procedure is described in more detail in the 2018 Technical Report filed on SEDAR on September 4, 2018.
