Torex Gold Reports Positive Drill Results From the 2020 Exploration Program at ELG Underground

 

 

 

 

 

Torex Gold Resources Inc. (TSX: TXG) announces drill results from the ongoing 2020 exploration program at the Company’s El Limón-Guajes underground mine, which includes the Sub-Sill deposit and the El Limón Deep deposit. Infill drilling at Sub-Sill returned positive results, with drilling intersecting similar grades and widths as within previous drill holes. Step-out drilling successfully extended known mineralization at Sub-Sill below the previous deepest hole, while continuing to extend the strike length of ELD. Skarn mineralization at both Sub-Sill and ELD remains open at depth.

 

Highlights from the latest round of drill results include 30.7 grams of gold per tonne over 9.1 metres in SST-162; 13.1 g/t Au over 28.5 m in SST-180; 23.9 g/t Au over 12.2 m and 14.9 g/t Au over 18.9 m in SST-169; 17.0 g/t Au over 15.4 m in SST-177; 21.6 g/t Au over 11.8 m in SST-189; and 16.0 g/t over Au 13.2 m in LDUG-071.

 

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

“We are pleased with the updated results from the 2020 underground exploration program at ELG, which reinforces confidence in our ability to extend the life of both Sub-Sill and ELD beyond current reserves. Drill results from Sub-Sill continue to impress, with step-out drilling extending known mineralization at depth a further 70 m, to a total of 300 m below current reserves. Infill drilling around previously drilled holes returned intersections with similar grades and widths.

 

“Our near-term mine planning focus at ELG is centered around maintaining a consistent production profile year over year, including during the transition period between ELG and Media Luna. These results are yet another step in demonstrating this potential as we target ongoing production of at least 20,000 ounces of gold per quarter from the ELG underground.”

Overview of 2020 ELG Exploration Program

 

Exploration will remain a key focus over the next few years as Torex looks to extend the current production profile of ELG through 2023 into 2024, and potentially beyond. Resource development and delineation drilling at Sub-Sill and ELD will be critical in achieving this objective, as it will allow Torex to develop mine plans for the deeper portions of both deposits, and begin developing these ore bodies in order to ensure consistent production of at least 20,000 ounces of gold per quarter from the ELG underground, in line with the +80,000 ounces produced from the underground in 2019. As an important part of this objective, and supported by positive indications of down-dip continuity of the skarn mineralization, the Company plans to invest additional funds into brownfields and near-mine exploration in 2021 and 2022.

 

Testing of depth extensions to both Sub-Sill and ELD is expected to pick up in late 2021 with the completion of Portal (#3) and related development. While the key benefit of Portal (#3) is expected to be up to a 50% reduction in underground haul distances, Portal (#3) will also allow for more effective targeting of deeper portions of both systems (Figure 1).

 

Torex continues to advance the primary objectives of the 2020 ELG exploration program, which are to:

 

      1)   Upgrade and expand resources within Sub-Sill;
      2)   Upgrade resources and test strike extensions of ELD;
      3)   Further delineate resources below the El Limón open pit in order to evaluate the potential of an additional pushback;
      4)   Test targets for new mineralized zones below the El Limón and Guajes open pits; and
      5)   Achieve 67,000 m of drilling.

Intersections reported in this press release are not reported as true thickness. Interval lengths for holes dipping between -45º and -90º have been selected to represent a minimum mining height of 3.5 m. Interval lengths for holes dipping between 0º and -45º have been selected to represent a minimum horizontal length of 3.5 m.

 

Currently, reported intersections from Sub-Sill and ELD demonstrate the continuity of potentially economic gold mineralization for at least 350 m along strike at ELD and 350 m down-dip below current development levels at Sub-Sill; apparent widths vary from 3.5 m to 46 m.

 

For a comprehensive summary of the latest results from the 2020 drill program, please refer to Table 2 of this press release for Sub-Sill results and Table 3 for ELD results.

 

Summary of Drill Results – Sub-Sill Deposit (Figures 2 and 3)

 

The 2020 exploration program at Sub-Sill has been focused on step-out drilling and resource infill drilling. Through Q3 2020, 22 holes and more than 10,100 m have been drilled, with the results confirming the continuity of high-grade mineralization of the deposit below current reserves.

 

Key highlights from the infill program include 13.1 g/t Au over 28.5 m (including 28.6 g/t over 6.2 m) in SST-180; 23.9 g/t Au over 12.2 m and 14.9 g/t Au over 18.9 m in SST-169; 30.7 g/t Au over 9.1 m (including 66.5 g/t over 3.5 m) in SST-162; and 6.3 g/t Au over 19.6 m (including 13.9 g/t over 3.6 m) in SST-175.

 

Step-out drilling was successful in extending mineralization 70 m below the previous deepest hole at Sub-Sill, with mineralization now extending over more than 300 m below the lower elevation of mineral reserves at year-end 2019. Two deeper holes drilled returned favourable results of 21.6 g/t Au over 11.8 m (including 38.1 g/t over 3.6 m) in SST-189 and 9.6 g/t Au over 11.0 m in SST-162.

 

Ongoing exploration is currently focused on infill drilling along the southern portion of Sub-Sill and testing potential lateral extensions of the deposit to the north and south.

 

Step-out drilling targeting deeper extensions of Sub-Sill is expected to commence in late-2021 once development of the new Portal (#3) has been completed. In addition to reducing underground haul distances by up to 50%, Portal (#3) is expected to provide better drilling access to target down-dip extensions of both Sub-Sill and ELD at depth, as well as allow for more efficient resource infill drilling.

 

Summary of Drill Results – ELD Deposit (Figures 4 and 5)

 

The 2020 exploration program at ELD has been focused on resource infill drilling and step-out drilling along the northern and southern extents of the deposit. Key results from the most recent 45 drill holes (8,100 m) include 16.0 g/t Au over 13.2 m (including 25.4 g/t over 6.2 m) in LDUG-071, 20.4 g/t Au over 6.9 m in LDUG-061, and 10.9 g/t Au over 9.8 m in LDUG-075.

 

Step-out drilling was successful in extending mineralization 150 m to the north from current mineral reserves and down to the 785 m elevation level, with favorable results including 9.1 g/t Au over 4.2 m in LDUG-081 and 5.0 g/t Au over 9.5 m in LDUG097.

 

Geology

 

The ELD and Sub-Sill deposits are distinct portions of the larger El Limón Guajes mineralized skarn system. The two deposits occur in different locations relative to a granodiorite sill prevalent in the deposit area and are approximately 300 m apart.

 

The El Limón Guajes mining complex, located in the central part of the Guerrero Gold Belt in Southwest Mexico, 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 mineralized skarn forms a single and continuous 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.

 

Mineralization in the Sub-Sill area formed along contacts between marbles of the Morelos formation and granodiorite sills, which are interpreted as late stage porphyritic intrusions that branch off the main body of granodiorite. The best developed skarn zones at the Sub-Sill area strike northeast and dip between 35° and 45° to the northwest. Deep drilling has identified a steeply dipping extension of the Sub-Sill skarn zone with high grade mineralization. This zone is currently interpreted as the structurally controlled feeder of the mineralization that developed along the lithological contacts between the hornfels, the marbles, and the sills. The skarn zone hosts multiple horizons with high-grade gold mineralization that vary in strike length from approximately 50 m up to 200 m, with apparent widths varying from 2 m to 36 m. The trend of the overall skarn body in the Sub-Sill area is north-south to northeast-southwest.

 

The style of mineralization at both deposits 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 controlled primarily 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.
