Torex Gold Outlines Multi-Year Exploration Strategy

(All amounts expressed in U.S. dollars unless otherwise stated)

Toronto, Ontario--(Newsfile Corp. - June 10, 2024) - Torex Gold Resources Inc. (the "Company" or "Torex") (TSX: TXG) is pleased to provide detail on a multi-year exploration strategy for its highly prospective Morelos Property ("Morelos"), designed to generate incremental additions to mineral resources in the near term, generate at least one new discovery in the mid-term, and extend the mine life at Morelos in order to deliver stable production and cash flow well beyond 2033.

Jody Kuzenko, President & CEO of Torex, stated:

"Since 2021, our exploration strategy has been focused on shoring up the near-term production profile and identifying future sources of feed to fill the mill beyond 2027. With these two business priorities well advanced, our drilling and exploration programs over the coming years will be increasingly focused on demonstrating the multi-decade potential of Morelos by delineating new deposits within the Media Luna Cluster and making new discoveries across the broader property.

"As our understanding of the structures and systems that control mineralization at Morelos continues to evolve, we are now broadening the search to grow organically through the identification of several new and promising targets including Todos Santos, El Naranjo, and Atzcala. In order to prioritize these targets to align within the Company's strategic priorities, our Exploration team has developed a systematic approach for evaluation on both a geologic and economic basis, culminating in the development of a new multi-year exploration and drilling strategy.

"The increased focus on identifying additional sources of feed across Morelos over the coming years will continue to be complemented by the near-mine drilling aimed at extending the life of both ELG Underground and Media Luna, expanding resources and delineating reserves at EPO, and drill testing Media Luna West and Media Luna East, two high priority targets that we expect will heavily utilize infrastructure currently being built as part of the scope of the Media Luna Project.

"Morelos is a prolific, world-class asset. Consistent with our approach in all other facets of our business, we intend to leverage a systematic, data-driven exploration and drilling strategy that will solidify Morelos as a foundational asset from which to grow the Company and deliver long-term shareholder value."

EXPLORATION STRATEGY OVERVIEW

Morelos is a 29,000-hectare land package that is situated within the heart of the Guerrero Gold Belt and includes the El Limón Guajes ("ELG") Mine Complex, the Media Luna Project, a processing plant, related infrastructure, and a number of exploration targets. The $31 million average annual investment in drilling and resource expansion since 2021 and $30 million budgeted for 2024 demonstrate the Company's strategic priority of unlocking the full mineralized potential of Morelos. Given existing knowledge of the geology of the property and the fact that 75% of the land package remains unexplored, Morelos remains highly prospective with respect to the delineation of additional gold, copper, and silver mineralization beyond what has been identified to date.

The Company's new multi-year exploration strategy is expected to enable Torex to deliver on its objective to maintain more than 450,000 gold equivalent ounces ("oz AuEq") of production annually beyond 2027 and to make at least one new discovery at Morelos in the coming years. The exploration and drilling strategy will focus on three distinct areas:

• Extending the mine life of ELG Underground and Media Luna: Delineating higher-value ore to extend the life of mine plan at Morelos by defining upside at ELG Underground and Media Luna through infill and near-mine step-out drilling;

• Expanding resources within the Media Luna Cluster: Enhancing and extending the production profile by unlocking the full potential of the Media Luna Cluster, including zones currently identified as Media Luna, EPO, Media Luna West, Media Luna East, and Todos Santos;

• Advancing targets through the growth pipeline: Strengthening the exploration target pipeline to deliver new discoveries across Morelos by prioritizing best-ranked projects, including zones currently identified as El Naranjo, Atzcala, Esperanza, Querenque, Tecate, El Olvido, and Victoria.

The Company's understanding of the structural controls of the mineralization is evolving and the current interpretation is that there are at least three dominant styles of mineralization present at Morelos: skarn, intermediate sulphidation ("IS"), and carbonate replacement deposits ("CRD"). As the knowledge matures and new exploration techniques are tested, uncovering additional upside at previously explored deposits bolsters confidence about the property-wide potential to host new deposits.

EXPLORATION STRATEGY EXECUTION

The Company has identified several exploration targets across Morelos (Figure 1) that are at various stages of development as depicted in the exploration pipeline (Figure 2). These range from the earliest stage of target selection, to target definition, through to exploration and drilling, resource delineation, and, at the most defined level, reserve definition to assess economic viability.

The goal is to advance each of the targets in the exploration pipeline and, pending the establishment of economic resources, ultimately bring them into production. Priorities amongst these targets will shift based on their economic potential and their ability to fulfill the Company's strategic objectives.

ELG Underground

The 2023 ELG Underground drilling program was successful in expanding Measured & Indicated Resources by 570 thousand oz AuEq prior to mine depletion (432 koz AuEq after depletion). The success of the drill program resulted in Proven & Probable Reserves increasing by 280 thousand oz AuEq prior to processed depletion (146 koz AuEq after depletion), thereby extending the mine life of ELG Underground by two years through 2028 (see Tables 1 and 2 of this news release for more information on mineral reserves and resources).

Building off the success of the 2023 program, the 2024 drilling program is exploring where the identified mineral corridors (or trends) intersect the La Flaca and Z71 faults. The program will test the potential for high-grade mineralization along the El Limón Sur and El Limón Deep trends and the potential to extend high-grade resources within the Sub-Sill and El Limón West trends. Given a consistent history of reserve replacement and resource growth, ELG Underground is expected to remain a key focus of future drilling programs.

Media Luna Cluster

The Media Luna Cluster is comprised of the Media Luna and EPO deposits as well as the high-priority drill targets Media Luna West, Media Luna East, and Todos Santos. The main Media Luna deposit is characterized by the distribution of north-northeast and west-northwest dikes on the flank of the Cuajiote fault, which control and define the distribution of gold, silver, and copper mineralization. Media Luna contains 4.6 million oz AuEq of Measured & Indicated Resources, with an additional 1.0 million oz AuEq in Inferred Resources and has additional upside at depth confirmed by preliminary drilling that intercepted similar grade mineralization as the current resource. Testing mineralized potential at depth will be the subject of follow-up drilling after construction of the Media Luna Project is complete.

Given the success of step-out drilling at EPO in 2023, which saw Indicated Resources expand to more than 1.1 million oz AuEq and the Inferred Resources upgraded to Indicated largely replaced, approximately $10 million is budgeted at EPO to conduct more than 24,000 metres ("m") of infill and expansionary drilling in 2024. The 2024 program is aimed at upgrading additional underground resources to the Indicated category while further expanding Inferred Resources. More than 700 thousand oz AuEq remain in Inferred Resources and any further category upgrades will further enhance the economics of EPO.

Based on the mine design envisioned in an internal pre-feasibility study that is currently underway, and if determined to be economic, the Company anticipates a similar path of development at EPO as was undertaken at ELG Underground, with throughput gradually increasing as the underground deposit is developed. This design approach, combined with the ability for EPO to leverage infrastructure now being built at Media Luna, is expected to result in a capital-efficient development project. High-level results of the internal pre-feasibility study are expected to be released later this year.

At Media Luna West, the first drilling since 2012 was conducted in 2023 and yielded positive results. As an advanced exploration target, 12,000 m of follow-up drilling is planned in 2024 to further define the deposit's resource potential. Media Luna West, an underground target, sits approximately 1.5 kilometres ("km") to the west of Media Luna and should also benefit from infrastructure developed as part of the Media Luna Project.

Todos Santos is a promising underground target that was advanced to the initial drill testing stage in 2023. Todos Santos exhibits encouraging magnetic anomalies, potentially indicative of blind mineralization with no surface expression, which will be further explored through the 3,000 m of drilling planned in 2024. The target is strategically positioned along the pronounced north-south structural corridor, bridging the gap between ELG and the Media Luna Cluster, running parallel to the Guajes Tunnel. Outcropping skarn mineralization with multiple old copper workings as well as gold anomalies in breccia outcrops were discovered during grassroots exploration at Todos Santos. Although early stage, Todos Santos has shown signs that it may potentially have a higher proportion of copper to gold than exists at Media Luna, which could support higher future copper production if the deposit is deemed economic.

The extent of Media Luna's mineralization to the east remains unknown. The Company has recently commenced discussions with local Ejidos regarding drilling access. If and as an agreement is achieved, Media Luna East is expected to become a priority underground target with potential for drilling to commence as early as 2025. Similar to EPO, Media Luna East would benefit from infrastructure being developed as part of the Media Luna Project.

Regional Exploration

The 2024 exploration budget includes $3 million allocated for regional exploration. In 2024, 3,000 m of intermediate drill testing is planned at El Naranjo, focused on completing the geological delineation and moving the three best areas into the advanced exploration stage. Preliminary surface works confirm the presence of oxidized gold mineralization within IS veins and breccia bodies, which serve as vectors to Media Luna-type CRD systems at depth.

Atzcala is currently at the target selection stage. The goal this year is to complete a geological evaluation of a 15 km x 5 km area, which will include hyperspectral drone surveys, high resolution magnetometry, and systematic rock geochemistry. The best-ranked area within Atzcala based on geological criteria is expected to be advanced to the target definition stage.

Within the regional exploration program, there are also plans to explore the north side of the Balsas River, looking for potential extensions to and/or the identification of new structural corridors, similar to those identified at the ELG deposit.

Longer-Dated Targets

In addition to the priority targets for 2024, the Exploration team has a number of other projects in the pipeline that are longer dated. As the Media Luna Project has substantially advanced, exploration has commenced from platforms situated in the northern areas of the Guajes Tunnel. During excavation, underground crews encountered many indications through mapping, channel sampling, and visible chalcopyrite, that there may be mineralization along the 7 km Tunnel from ELG to Media Luna. No further exploration has been undertaken in the southern end of the tunnel as completion of the Media Luna underground construction remains the priority.

Other longer-dated targets that have yielded encouraging results in early geological work include Querenque, Tecate, Esperanza, El Olvido, and Victoria. While not a priority focus in 2024, these areas will be evaluated and advanced as appropriate in the exploration pipeline over the coming years.

IDENTIFYING & PRIORITIZING TARGETS

Torex has undertaken a refreshed approach to exploration and drilling since 2021 that included appointing a Vice President of Exploration and enhancing the depth of experience on the Exploration team. To date, the team has studied both recent and historic drilling data, which provided a framework for a technical reinterpretation of the geochemical, geophysical, and remote sensing studies completed in the Morelos district. This reassessment was a key factor in re-evaluating the mineralization model, now thought to include CRD and IS systems in addition to skarn. As expected in a complex system, some of these mineralization styles overlap, which can enrich their gold content.

The evolution of this geological understanding is supported by a comprehensive process of evaluating and ranking the targets identified to date. The exploration pipeline was produced to effectively sort these targets into defined exploration stages. The aim is to systematize and add transparency to the ranking process by comparing projects at a similar exploration stage, assessing each target based on several factors including mineralization style, geology, geography, and economic potential. Working with the Technical Services team, the results of this ranking system can be used to support future capital allocation priorities of the Company.

This process delivers a geological ranking that will be reassessed each year, as exploration advances, to consider both economic and strategic criteria, culminating in an exploration budget proposal for the following year. A multi-year plan will then be formulated by projecting the anticipated advancements of the project pipeline and estimating the proposed exploration and budgets at each exploration stage. Drilling and associated program costs are then estimated for each stage of the pipeline to define the level of investment for the multi-year period. As significant spending on the Media Luna Project winds down later this year, more funding is expected to be allocated in the coming years to further explore priority targets.

MORELOS PROPERTY GEOLOGY

On a regional scale, Morelos is situated in the Guerrero Gold Belt on the western edge of the Mixteca terrane which is composed of a pre-Carboniferous basement of metamorphic rocks of the Acatlán Complex, unconformably overlain by a thick succession of Cretaceous sedimentary rocks. These are known as the Morelos, Cuautla, and Mezcala Formations, which together form the Morelos-Guerrero basin.

The Cretaceous sedimentary successions of the Morelos-Guerrero basin, containing large expanses of carbonate (geochemically reactive) rocks are the major hosts for skarn mineralization in the area and consist of 600- to 1,000-metre-thick, shallow marine carbonate rocks of the Morelos Formation. This unit is mainly composed of calcareous limestones with some dolomite in lower units. The Morelos Formation is conformably overlain by the Cuautla Formation, characterized by limestones that gradually transition upward to pelagic limestones and siliciclastic rocks of the Mezcala Formation. The base of the Mezcala unit is dominated by gray limestones that gradually transition to shales, siltstones and sandstones, and conglomerates at the very top.

Cretaceous sedimentary rocks were folded into north-south-striking anticlines and synclines as a result of the accretion of the Guerrero composite terrane against the Mixteca terrane during the Laramide orogeny. Subduction of the Farallon Plate beneath the North American craton caused magmatism that resulted in the formation of Late Cretaceous-Paleocene diorites and granodiorites that intruded the folded and thrusted sedimentary units of the Morelos-Guerrero basin within the Mixteca Terrane.

At the property scale, structural deformation is dominated by west-northwest faults cut by first-order north-south faults, which are somewhat displaced by second-order northeast faults. Granodiorites and diorites intruded the folded sequence, which triggered the hydrothermal systems that gave rise to the mineralized deposits.

The known mineralized deposits at Morelos correspond to CRD, skarn, and IS mineralized styles hosted along contacts of the intrusive rocks and carbonate-rich sedimentary rocks of the Cuautla and Morelos formations, as well as along the footwall contact of the Mezcala Formation. At depth, the mineralization has a strong structural control related to the major north-south faults.

At a deposit scale, early-stage calc-silicate alteration is related to proximal skarn that evolves to CRD associated to copper and silver mineralization with a final IS-epithermal mineralization event that increases the gold volume and grade.

Dykes and sills are deemed the main ore control and traps of the mineralized bodies. Given that gold precipitates due to the buffer exerted by the early stage calc-silicate alteration and sulfide mineralization, it occurs as free gold and is dissociated from the previous copper event mainly related to chalcopyrite.

5.EPO Underground AuEq = Au (g/t) + (Ag (g/t) * 0.0130) + (Cu (%) * 1.6480), accounting for underlying metal prices and metallurgical recoveries for EPO Underground.

Notes to accompany the ELG Open Pit mineral resources:

1.The effective date of the estimate is December 31, 2023.
2.Mineral resources for ELG Open Pit are reported above an in-situ cut-off grade of 0.78 g/t Au.
3.Average metallurgical recoveries are 89% Au, 30% Ag, and 15% Cu.
4.Mineral resources are reported inside an optimized pit shell, underground mineral reserves at ELD within the El Limón pit shell have been excluded from the open pit mineral resources.
5.ELG Open Pit AuEq = Au (g/t) + (Ag (g/t) * 0.0045) + (Cu (%) * 0.2627), accounting for underlying metal prices and metallurgical recoveries for ELG Open Pit.
