Torex Reports Initial Results From the Media Luna In-Fill Diamond Drilling Program
TORONTO, Oct. 25, 2018 (GLOBE NEWSWIRE) -- Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX:TXG) announces the results from the first 23 holes, of a planned 175 hole, in-fill drilling program at its Media Luna Project in Southwest Mexico. Highlighted intercepts from this program include 10.5 g/t Au Eq. over 39.2 m in borehole ML18-222A; 7.0 g/t Au Eq. over 49.6 m in borehole ML18-215; 7.1 g/t Au Eq. over 45.9 m in borehole ML18-219W and 8.3 g/t Au Eq. over 22.6 m in borehole ML18-208W.
Fred Stanford, President & CEO of Torex stated: “Media Luna is our next planned growth project and it is being advanced on a number of fronts. One of those fronts was the recently refreshed PEA1, which illustrated an after-tax IRR of 27% using conventional mining technologies and 46% utilizing the proprietary, but untested, Muckahi Mining System1. Engineering optimization work is ongoing after the publication of the PEA.
A second front is the testing of the Muckahi Mining System at the Company’s ELG site. The first piece of Muckahi equipment is expected to ship to ELG before the end of this year, with significant testing of the system expected to be completed by year end 2019. Land lease negotiations for Media Luna have also been completed and permitting baseline work is underway.
Another major package of on-going work is the diamond drilling program to upgrade 25% of the Inferred Media Luna resource to the Indicated confidence category. This upgrade in confidence category is intended to enable the declaration of Media Luna reserves in a planned upcoming feasibility study. The Inferred resource was drilled out on 100m centers. To upgrade to the Indicated confidence category, the diamond drilling is targeted on 30m centers. As of the end of September, 23 holes had assays completed and are reported today. Results can most easily be described as “as expected”. There are some high-grade holes, some average holes, and some holes that intersected a dyke in the target zone. This is consistent with the results from the earlier 100m centers program and bodes well for the potential of the deposit to live up to expectations. There are currently 5 drills active on the Media Luna Project. On average each drill completes two holes per month, which suggests completion of the program at the end of 2019. Efforts are underway to source more water so the drill count can be increased.
There are several porphyry targets on the property and one of the higher priority targets is close to the Media Luna drill site. One of the drill crews will be diverted to test this target with three holes. This program is expected to get underway this quarter and be completed by the end of the first quarter of 2019.”

Notes to drilling results table:
- Intersections are reported as true thickness.
- The gold equivalent grade, including copper and silver values, are based on 100% metal recoveries. The gold grade equivalent calculation used is as follows:
Au Equivalent (Au Eq) = Au (g/t) + Cu % * (79.37/47.26) + Ag (g/t) * (0.74/47.26). Metal prices used are US$1470/oz of gold, silver price of US$23.00/oz and copper price of US$3.60/lb. Metal prices are as most recent resource statement.
- Intercepts in this press release were graded for compositing as follows:
- Includes all intersections greater than 2gpt Au Eq (COG as per the current Resource Statement);
- For lower grade sections that are bounded by results greater than 2gpt AuEq, they are included unless they are greater than 5m in true length.
Please refer to Table 1 for a complete list and expanded description of the borehole intercepts reported in this press release. Refer to Figure 1 for general location and Figures 2 to 6 for geology, borehole locations and assay results.
1 A preliminary economic assessment should not be considered a prefeasibility study or feasibility study, as the economics and technical viability of the Media Luna Project have not been demonstrated at this time. The Media Luna PEA (as defined below) is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. It cannot be assumed that all or any part of the inferred mineral resources will ever be upgraded to a higher category. Furthermore, there is no certainty that the conclusions or results as reported in the Media Luna PEA will be realized. Mineral resources that are not mineral reserves do not do not have demonstrated economic viability. The Media Luna PEA includes information on Muckahi. It is important to note that Muckahi is experimental in nature and has not been tested in an operating mine. Many aspects of the system are conceptual, and proof of concept has not been demonstrated.
The Media Luna deposit occurs within the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite to tonalite stocks, sills and dykes. Skarn-hosted gold-silver-copper mineralization is developed along the contacts of intrusive rocks and enclosing carbonate-rich sedimentary rocks. Sedimentary rocks and their contact with the main granodiorite stock dip southwest at approximately 35º. Extensive skarn alteration and metal deposition at this contact exhibits the same dip.
Gold–silver-copper mineralization at Media Luna is primarily associated with sulfidized pyroxene–garnet–magnetite exoskarn and with zones of massive magnetite-sulfide, at the contact of granodiorite with marble. Sulfidation of skarn assemblages is closely related to retrograde alteration. This alteration consists of amphibole, phlogopite, chlorite, calcite ± quartz ± epidote.

Additional information on the Media Luna deposit, the mineral resource estimate for the Media Luna Project, updated Media Luna Preliminary Economic Assessment (PEA) and analytical and sampling process is available in the Company’s technical report (TR) 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.
Torex is an intermediate gold producer based in Canada, engaged in the exploration, development and operation of its 100% owned Morelos Gold Property, an area of 29,000 hectares in the highly prospective Guerrero Gold Belt located 180 kilometers southwest of Mexico City. The Company’s principal assets are the El Limón Guajes mining complex (the “ELG Mine Complex”), comprised of the El Limón, Guajes and El Limón Sur open pits, the El Limón Guajes underground mine including zones referred to as Sub-Sill and El Limón Deep, and the processing plant and related infrastructure, which is in the commercial production stage as of April 1, 2016, and the Media Luna deposit, which is an early stage development project, and for which the Company issued an updated preliminary economic assessment in September 2018. The property remains 75% unexplored.
PRELIMINARY ECONOMIC ASSESSMENT
A preliminary economic assessment should not be considered a prefeasibility study or feasibility study, as the economics and technical viability of the Media Luna Project have not been demonstrated at this time. The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. It cannot be assumed that all or any part of the inferred mineral resources will ever be upgraded to a higher category. Furthermore, there is no certainty that the conclusions or results as reported in the Media Luna PEA will be realized. Mineral resources that are not mineral reserves do not do not have demonstrated economic viability.
The Media Luna PEA includes information on Muckahi. It is important to note that Muckahi is experimental in nature and has not been tested in an operating mine. Many aspects of the system are conceptual, and proof of concept has not been demonstrated. Drill and blast fundamentals, standards and best practices for underground hard rock mining are applied in the Muckahi, where applicable. The proposed application of a monorail system for underground transportation for mine development and production mining is unique to underground hard rock mining. There are existing underground hard rock mines that use a monorail system for transportation of materials and equipment, however not in the capacity described in the TR. Aspects of Muckahi mining equipment are currently in the design stage. The mine design, equipment performance and cost estimations are conceptual in nature, and do not demonstrate technical or economic viability. The approximate timeframe to develop and test the concept would be approximately two years (approx. second quarter 2020) for the mine development activities and up to five years for the mine production activities (approx. second quarter 2023). Further studies would be required to verify the viability of Muckahi. Muckahi is not intended as a “trade off study” but is shown to merely demonstrate the potential benefits Muckahi may have using the Media Luna deposit as an example. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
