Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX: TXG) announces results from the 2019 drill program at the Sub-Sill deposit, at the Company’s El Limón Guajes complex in Mexico. The 2019 program successfully extended known mineralization 300 metres below existing reserves. Highlights from the latest round of drill results include 35.1 g/t Au over 6.1 metres in SST-156, 21.6 g/t Au over 3.5 metres in SST-135, 19.5 g/t Au over 5.9 metres in SST‑139, 15.7 g/t Au over 5.2 metres in SST-132, and 13.8 g/t Au over 12.8 metres in LDGU-047. Mineralization at Sub-Sill remains open at depth and along strike. 

Fred Stanford, President & CEO of Torex Gold, stated:

“The down-dip extensions of the mineralization of both Sub-Sill and El Limón Deep (ELD), the latter highlighted in a press release earlier this month, are very encouraging. Sub-Sill has been an excellent ‘sweetener’ to the high-grade open pits. In the first three quarters of 2019, the deposit has contributed more than 60,000 ounces of gold production. The latest drill results show the potential of Sub-Sill to continue to be a sweetener well into the future. ELD is going to be a nice sweetener as well, and it is just getting started. 

“The first long-hole open-stope blast in ELD took place this week. In December, the site teams will be trialing the removal of ore from the stope utilizing the production aspects of the Muckahi Mining System. These are exciting times with drilling highlighting the potential to mine new zones of mineralization as well as testing of Muckahi, which has the potential to materially lower the cost of underground mining.”

A complete list of the most recent drill holes from the Sub-Sill drill program can be found in Table 2 of this press release. A longitudinal section containing the drill-hole results can be found in Figure 1 as well as corresponding cross sections in Figures 2, 3 and 4. GeologySub-Sill is classified as the mineralized skarn which lies beneath the granodiorite sill as shown in Figure 5. ELD is classified as the mineralized skarn, which sits below the El Limón open pit and above the granodiorite sill.

The Sub-Sill deposit occurs at the south end of the El Limón deposit in the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite stocks, sills and dikes. It is located below mineralization currently exploited by open pit mining in the El Limon mine. 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.

Multiple skarn zones have been recognized underneath the El Limón Sill, they are developed along the contacts between marbles of the Morelos formation and multiple granodiorite sills that 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 feeders of the mineralization developed along the lithological contacts between the hornfels, the marbles, and the sills (Figures 2, 3 and 4). The skarn zone hosts multiple horizons with high-grade gold mineralization that vary in strike length from approximately 50 meters up to 200 meters, with apparent widths varying from 2 metres to 36 metres. The trend of the overall skarn body in the Sub-Sill area is north-south to northeast-southwest and appears to connect to previously recognized skarn and gold mineralization at the El Limón Sur deposit 200 meters to the southwest.

Mineralization at the Sub-Sill deposit is dominated by gold, which is associated with bismuth and variable amounts of silver and copper. Mineralization is associated with retrograde alteration characterized by amphibole, calcite, and quartz, with lessor amounts of chlorite ± epidote, affecting pyroxene-garnet exoskarn and granodiorite-related endoskarn. Locally, mineralization occurs in narrow lenses of massive sulfides.

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 metres. Interval lengths for holes dipping between 0º and -45º have been selected to represent a minimum horizontal length of 3.5 metres. Currently reported intersections also demonstrate the continuity of potentially economic gold mineralization for at least 100 metres along strike and 300 down-dip; apparent widths vary from 3.5 metres to 46 metres.

CAUTIONARY NOTES

Muckahi Mining SystemThe Technical Report 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 Technical Report. Aspects of Muckahi mining equipment are currently in the design and test stage. The mine design, equipment performance and cost estimations are conceptual in nature, and do not demonstrate technical or economic viability. The Company expects to complete the development and test the concept by the end of 2019 for the mine development and production activities. Further studies would be required to verify the viability of Muckahi.
