Torex Gold Resources Inc. (TSX: TXG) announces results from the 2019 drill program at the El Limón Deep deposit, at the Company’s El Limón Guajes complex in Mexico. The 2019 program has been successful in extending mineralization 150 metres down-dip from current reserves as well as along strike to the south. Highlights from the latest round of drill results include 15.6 g/t Au over 38.0 metres in LDUG-039, 28.5 g/t Au over 5.8 metres in drill-hole LDUG-049, 20.9 g/t Au over 12.0 metres in LDUG-056, and 15.7 g/t Au over 16.8 metres in LDUG-036. Mineralization at ELD remains open in multiple directions.
Fred Stanford, President & CEO of Torex Gold, stated:
“These excellent results show the potential to extend the reserves down-dip and along strike to the south, as illustrated in Figures 1 and 2. The current reserves for ELD extend 150 metres down-dip. Extending the mineralization for another 150 metres down-dip has the potential to materially extend the mine life of ELD. The mineralization is still open at depth, and this opportunity will be drill tested in 2020. The current average reserve grade of ELD is 5.5 g/t. As noted in Table 1, many of the down-dip intersections are considerably above that grade. The deposit appears to be steepening at depth, which bodes well for low cost bulk mining techniques.
“We also tested for extensions along strike. The low-grade intersections shown in Figure 3 indicate that we found the northern limit of the strike extension at depth. We are unlikely to mine that area. The deposit remains open along strike to the south. The last three holes in Table 2 were targeting the Sub-Sill deposit, but also intersected the El Limón skarn above the sill. Figure 4 illustrates how that happened.”

A complete list of the most recent drill holes from the ELD drill program can be found in Table 2 of this press release.
ELD is classified as the mineralized skarn, which sits below the El Limón open pit and above the granodiorite sill. Sub-Sill is classified as the mineralized skarn which lies beneath the granodiorite sill.
The ELD zone occurs in the northwest portion of the El Limón deposit, which is part of the large gold bearing skarn system of the El Limón Guajes mining complex, located in the central part of the Guerrero Gold Belt in Southwest Mexico. The El Limón Guajes deposit is hosted in the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite stocks, sills, and dikes. Skarn-hosted gold mineralization is developed along the contacts of the intrusive rocks and the enclosing carbonate-rich sedimentary rocks of the Cuautla and Morelos formations as well as along the footwall contact of the Mezcala Formation. ELD represents the down-dip extension of the skarn that hosts the gold mineralization at El Limón open pit, where the skarn is developed immediately above a large granodiorite sill intruded along the contact of the Cuautla and the Mezcala formations. The ELD deposit is located directly below the deepest part of the El Limón final pit and is above the El Limón “Sill”. It lies approximately 300 metres north and at a higher elevation than Sub-Sill but has the same general orientation in strike and dip.
The southeast portion of ELD mineralization is characterized by a single and continuous skarn package that strikes approximately 10° to the north-northeast and dips between 30° and 35° to the northwest. To the northwest, the strike of the skarn package changes to approximately 155° (south-southeast) and the dip steepens to approximately 60°. The change in the geometry of the skarn package is interpreted to be related to the northeast striking and southeast dipping La Flaca Fault; parallel structures are locally represented by post mineral dykes.
The currently known, best-developed skarn zone at ELD is in the central part of the drilled area immediately north of the La Flaca fault and below the deepest part of the El Limón pit. The initial infill exploration program has been concentrated in this area and has confirmed the continuity of the mineralization intersected in earlier, widely spaced holes. Mineralization remains open along strike especially to the southeast and down-dip to the southwest. Additional mineral potential is envisaged in the multiple skarn zones identified at depth.
Intersections reported in this press release are not reported as true thickness. Interval lengths for holes dipping between -45º to -90º have been selected to represent a minimum mining height of 3.5 metres. Interval lengths for holes dipping between 0º and -45º have been selected to represent a minimum horizontal length of 3.5 metres. The program also demonstrates the continuity of the high-grade gold mineralization for at least 150 metres along strike and 150 down-dip; apparent widths vary from 3.5 metres to 46 metres.
The style of mineralization at ELD is similar to the mineralization in the other mineralized zones within the El Limón Guajes deposit. It is characterized by gold, which is strongly associated with bismuth and variable amounts of silver and copper. Gold occurs in variably sulfidized, pyrrhotite-rich skarn, while silver and copper mineralization is primarily controlled by the degree of sulfidation of the host skarn. Mineralization is associated with retrograde alteration characterized by the occurrence of phlogopite, amphibole, chlorite, calcite and lesser amounts of quartz and epidote, and local magnetite.
QA/QC and Qualified Person
Torex maintains an industry-standard analytical quality assurance and quality control and data verification program to monitor laboratory performance and ensure high quality assays. Results from this program confirm reliability of the assay results. All sampling and analytical work for the mine exploration program is performed by SGS de Mexico S.A. de C.V. in Durango, and by SGS in Nuevo Balsas, Mexico. Gold analyses comprise fire assays with atomic absorption or gravimetric finish. External check assays for QA/QC purposes are performed at ALS Chemex de Mexico S.A. de C.V.
The analytical QA/QC program is currently overseen by Carlo Nasi, Chief Mine Geologist for Minera Media Luna, S.A. de C.V.
