Torex Gold Provides Progress Update on Media Luna
October 6, 2021
TORONTO, Oct. 06, 2021 (GLOBE NEWSWIRE) -- Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX: TXG) provides a progress update on the Media Luna project, affirming that a property-wide Technical Report, including the Media Luna Feasibility Study, remains on schedule for completion in Q1 2022. The Company is also pleased to announce the appointment of Dave Stefanuto as Executive Vice President (“EVP”), Technical Services and Capital Projects, who will be accountable for delivering Media Luna from Feasibility Study through handover to operations.
Jody Kuzenko, President & CEO of Torex, stated:
“We continue to advance our strategic objective to de-risk and advance Media Luna, which includes execution of our early works program to access the deposit from both the north and south sides of the Balsas River, continuation of the infill drilling program, and advancement of the permitting plan. Importantly, we are also well on track to deliver the Media Luna Feasibility Study as part of a broader Technical Report to be released in Q1 2022.
“As we continue to advance the Feasibility Study, we have made a number of decisions to optimize the Media Luna project from that which was set out in the 2018 Preliminary Economic Assessment (“PEA”). These decisions are also being made with a view to deliver a smooth ramp up as we transition from open pit production at ELG, and to incorporate potential sources of feed from the wider Morelos property, as exploration is expected to become a greater focus for the Company over the coming years.
“I am also very pleased to announce the appointment of Dave Stefanuto as EVP, Technical Services and Capital Projects, who will lead the Media Luna project though handover to operations. Dave is a seasoned executive with a proven track record leading major capital projects in both surface and underground mining operations. He will be an exceptional addition to our team due to his technical capabilities, senior project experience and collaborative leadership style.”
ENGINEERING ON SCHEDULE
Engineering related to mine design, mine access, and upgrades to the processing plant are advancing on schedule. Since the September 2018 PEA was released, the Company has made several design decisions that consider:
- A better understanding of the deposit based on tighter-spaced infill drilling;
- Trade-off studies optimizing mine design and access, process plant recoveries, and tailings management;
- Risk mitigation with respect to project permitting, schedule, execution, and operations; and
- Flexibility to take advantage of future potential sources of feed on the south side of the Balsas River.
Access and Material Handling
As previously announced, primary access to the Media Luna deposit will be through the 7-kilometre long Guajes Tunnel, which is currently being driven from the north side of the Balsas River. Access from the south side of the river will be available through the construction of South Portal Upper and South Portal Lower. Access to the Media Luna deposit from both sides of the river replaces the 2018 PEA design of access from only the north side via a ropeway and suspended conveyor.
Constructing the Guajes Tunnel under the river was the selected solution for transporting ore, waste, backfill, equipment, supplies, and personnel versus the over the water option envisioned in the 2018 PEA. The tunnel will set up the operation for potential future discoveries south of the river, including high priority targets in close proximity to Media Luna, as well as other regional targets. A final trade-off study on using a fixed conveyor or haul trucks to transport ore through the Guajes Tunnel is nearing completion.
South Portal Upper and South Portal Lower provide multiple benefits including improved ventilation and additional points of access and egress for personnel, equipment, and supplies from the south side of the Balsas River. The two portals will also allow for the development of the upper, middle, and lower portions of the deposit ahead of completion of the Guajes Tunnel, with the aim of providing for sufficient stopes to deliver a smooth ramp-up (see Figure 1). South Portal Lower will also allow the Company to commence development of the Guajes Tunnel from the south side of the river, reducing schedule risk compared to tunnelling only from the north side.

Water Treatment Plant
The Media Luna process flowsheet has been refined since the 2018 PEA was released, which has identified the need for a water treatment facility to provide cleaner water to the copper and iron sulphide flotation circuits. These circuits will be added to the current process flowsheet to produce a saleable copper concentrate (including gold and silver), and to recover additional gold and silver in the form of doré. The upgraded circuit will allow for processing of ore from both Media Luna and El Limón Guajes (“ELG”).
As noted previously, the Company is currently evaluating the option of bringing the installation of the flotation circuits and water treatment plant earlier in the schedule to process higher copper and iron sulphide ores at ELG.
Detailed mine design work, which has enabled a better understanding of the deposit through tighter spaced infill drilling, indicates an underground operation capable of delivering an average steady-state mining rate of 7,500 tonnes per day. From 2018 through completion of Phase I of the 2021 program, 150,000 metres of infill drilling have been completed with drill spacing reduced to 30 metres (Indicated) from 100 metres (Inferred).
The size of the underground fleet is expected to be larger than outlined in the 2018 PEA based on initial mine planning and increased development requirements ahead of commencing underground production. First production is anticipated in Q1 2024 followed by a ramp-up period that is expected to continue for a number of quarters to achieve steady-state mining rates.
Further upside is possible should the nearby EPO deposit be developed. Although EPO was included in the early years of the 2018 PEA mine plan, EPO will not form part of the Feasibility Study mine plan as the full resource is currently classified as Inferred (1.01 million gold equivalent ounces – 8.0 million tonnes at an average gold equivalent grade of 3.93 g/t). 1 The 2018 PEA envisioned EPO contributing 3.8 million tonnes of ore to the processing plant over the first five years of the 2018 PEA mine plan. Infill drilling at EPO is expected to be part of future exploration efforts at Media Luna.

The back end of the processing plant, comprised of copper and iron sulphide flotation circuits required to treat ore from Media Luna, is expected to be sized at 11,000 tonnes per day. This will provide sufficient capacity to process ore from Media Luna, the ELG Open Pit as it winds down, ELG Underground, and stockpiled material.
The anticipated throughput will also provide capacity to process potential sources of feed, including EPO, as well as future discoveries on the broader Morelos property. As previously noted, exploration is expected to be a greater focus for Torex going forward as the Company looks to replace reserves and grow resources through brownfield and greenfield exploration programs.
INFILL DRILLING ON SCHEDULE
At the end of August, the Company had received a majority of the assay results from Phase 1 of the 2021 infill drilling program. The Phase 1 program consists of 161 holes totaling 44,000 metres. Assay results for the first 38 holes (approximately 11,800 metres) were previously released and included in the April 2021 mineral resource estimate. Assay results for the remaining drill holes are expected to be released in the coming weeks.
Phase 2 of the 2021 infill drilling program has commenced with an additional 39,000 metres planned. Results from a portion of the Phase 2 program are expected to be incorporated into the next resource estimate, which will form the basis for mine plan in the upcoming Media Luna Feasibility Study. Results from the Phase 2 program are expected to be released in Q1 2022.
In total, Torex expects to invest $20 million in 2021 towards infill drilling at Media Luna. Pending Board approval, a subsequent robust drill program is expected for Media Luna in 2022, which is likely to include infill drilling at the EPO deposit in order to upgrade Inferred mineral resources to the Indicated category. Step-out drilling is also expected to resume as the Company seeks to expand the overall size of the resource. To date, only approximately 30% of the magnetic anomaly that hosts the Media Luna deposit has been drill tested.
TECHNICAL REPORT ON SCHEDULE
An updated Technical Report for the entire Morelos Property is on track for completion in Q1 2022. The Technical Report will include a Feasibility Study for Media Luna as well as updated mine plans for the ELG Open Pit (including the recently approved El Limón pushback) and ELG Underground (incorporating results of 2021 infill drilling program).
Operating costs to be outlined in the Technical Report will leverage current processing and site costs for ELG, more detailed mine design and planning for Media Luna, and up to date costing for key consumables and labour.
Capital costs will be refined as engineering progresses and will incorporate current vendor quotes. Capital costs relative to the 2018 PEA are expected to be impacted by industry-wide inflation given elevated prices for key construction materials (steel, cement, and copper), scope changes related to the design of the project, as well as costs associated with COVID-19.
PERMITTING ON SCHEDULE
Permitting activities are well advanced and on schedule. Following receipt of the MIA Modification earlier this year, the Company has the necessary approvals to advance early-work activities on both sides of the Balsas River. The Company has also received environmental authorization to continue the Guajes Tunnel under the Balsas River. The remaining approval is the MIA Integral, for which an application was submitted to SEMARNAT for review in July 2021.
