Torex Gold Reports Results From The Ongoing
2024 EPO Exploration Program
Results indicate strong potential to upgrade Inferred
Resources to Indicated Resources and expand resources to
the north of the deposit
(All amounts expressed in U.S. dollars unless otherwise stated)
Toronto, Ontario--(Newsfile Corp. - November 13, 2024) - Torex Gold Resources Inc. (the "Company" or
"Torex") (TSX: TXG) announces assay results from the Company's ongoing drilling program at EPO. The
results to date support Torex's goal of expanding resources to the north of the deposit and upgrading
Inferred Resources to Indicated Resources.
Jody Kuzenko, President & CEO of Torex, stated:
"The results from the first half of EPO's 2024 exploration and drilling program build on the success of the
drilling programs conducted over the last few years. Drilling has confirmed mineralization extends
beyond defined resources to the north and also indicates high potential to convert Inferred Resources to
Indicated Resources in both the south and the northeast of the deposit. The expansion of resources to
the north reinforces the underlying potential for EPO and, if follow-up drilling is successful, could open up
new operating fronts to support additional production from EPO beyond what was outlined in the internal
prefeasibility study released in September.
"We look forward to seeing the results from the second half of the 2024 program, which I expect will
further indicate the potential to build on our resource inventory with the year-end mineral reserve and
resource update and support the Company's target of sustaining annual gold equivalent production
between 450,000 to 500,000 ounces beyond 2030. With only a few months remaining before Media
Luna delivers first production and the Company returning to a strong free cash flow position, EPO is
setting the stage for the capital efficient growth potential we see within the Media Luna Cluster and
across the whole Morelos Property."
HIGHLIGHTS
Within the northeastern portion of the EPO deposit, drilling has highlighted the potential to upgrade
Inferred Resources to Indicated Resources, with the most notable intercepts from drill hole ML23-
1009 which returned
10.67 grams per tonne gold equivalent ("gpt AuEq") over 36.6 metres
("m"), including 44.80 gpt AuEq over 7.6 m;
and drill hole ML23-1001 which returned
6.82 gpt
AuEq over 18.9 m
.
Drilling directly south of the defined resource encountered mineralization, highlighting the potential
to expand Indicated Resources in that direction. Most notably, drill hole ML24-1035D intercepted
5.70 gpt AuEq over 7.5 m
.
Drilling has also confirmed the expansion of mineralization to the north of EPO and has defined a
northwest corridor with at least 100 m of vertical continuity. Notably, drill hole ML24-1017, a follow-
up of drill hole ML23-942 (6.14 gpt AuEq over 15.8 m; press release dated September 5, 2023),
intercepted
6.35 gpt AuEq over 5.1 m
.
2024 EPO DRILLING & EXPLORATION PROGRAM
EPO currently hosts a gold equivalent Indicated Resource of over 1.15 Moz AuEq at a grade of 5.14 gpt
AuEq and an Inferred Resource of over 0.72 Moz AuEq at a grade of 4.52 gpt AuEq.
1
The focus of the
2024 drilling program at EPO is to upgrade Inferred Resources to Indicated Resources as well as
expand the overall resource footprint, specifically to the north.
Assays for 22 holes drilled in 2023 that were received after the cut-off date to be included in the year-end
2023 mineral resource estimation have been included in this press release. For the 2024 program, 15
drill holes totalling 9,860 m drilled through the first three quarters of the year have been included. Results
to date support the ability to grow Indicated Resources and expand Inferred Resources.
Torex has budgeted approximately $10 million for the 2024 drilling and exploration program at EPO.
Drilling is progressing with four rigs and the Company is forecasting to achieve a forecast of 21,000 m
by the end of the year.
Detailed drill results are reported in Table 4 (2023 results) and Table 5 (2024 results).
Drill hole intercepts are core lengths and not true widths. True width will be determined once the
geological modelling to define the ore controls is completed. The gold equivalent grade calculation
accounts for the same metal prices ($1,650/oz gold ("Au"), $22/oz silver ("Ag"), and $3.75/lb copper
("Cu")) as well as metallurgical recoveries (87% Au, 85% Ag, and 92% Cu) used in the current mineral
resource estimate for the EPO deposit (effective date of December 31, 2023).

Mineral resource estimates for the Morelos Complex can be found in table 3 of this news release. AuEq values account for underlying metal
prices and metallurgical recoveries used in resource estimates. For additional information on the mineral resource estimates for the Morelos
Complex, please see the Company's Annual Information Form dated March 27, 2024 filed on SEDAR+ at

RESOURCE DELINEATION DRILLING PROGRAM
The strong results from the 2023 EPO drilling program wherein the quality and continuity of the
mineralization was identified to the south of the deposit has underpinned the 2024 Resource Delineation
drilling program. Six drill holes to date have returned favourable intercepts in the southern area of EPO,
with the most notable being ML24-1035D (4.37 gpt AuEq over 10.5 m) and ML24-1037DA (5.12 gpt
AuEq over 9.7 m). The drilling indicates the potential to upgrade Inferred Resources to Indicated
Resources with the 2024 year-end mineral reserve and resource update.
These mineralized intercepts show a strong structural control, with mineralized ore shoots at the hanging-
wall of the dikes containing up to 10 m of vertical extension and lateral continuity of at least 75 m.

Notes to Table:
1)
Intercepts are reported as core length (not true width/thickness). True width/thickness will be determined once the geological modelling to
define the ore controls is completed.
2)
Core lengths reflect drilling core recovery >98%.
3)
The gold equivalent grade calculation used is as follows: AuEq = Au (gpt) + (Ag (gpt) * 0.0130) + (Cu (%) * 1.6480) and use the same metal
prices ($1,650/oz Au, $22/oz Ag, and $3.75/lb Cu) and metallurgical recoveries (87% Au, 85% Ag, and 92% Cu) used in the year-end 2023
mineral resource estimate for EPO Underground.
To the southwest, mineralized intercepts are more discrete, with drill widths of less than 2 m and grades
ranging from 3 to 7 gpt AuEq. Drilling from surface has been complex due to the presence of the clay-
rich Copalillo fault zone, which resulted in two drill holes being abandoned this year.
To the northeast of the defined Inferred Resources, mineralization encountered in drill holes ML23-1009
(10.67 gpt AuEq over 36.6 m, including 44.80 gpt AuEq over 7.6 m) and ML23-1001 (6.82 gpt AuEq
over 18.9 m) highlights the potential for Inferred Resources to be converted to Indicated Resources. This
area will be subject to Resource Delineation drilling later this year once the geological modelling to
define the ore controls is completed.
As part of the 2025 exploration program, the Company is evaluating an approximately 600 m exploration
drift from South Portal Upper directly north over the upper portion of reserves at EPO at the 970 m
elevation. This drift, as well as the lower elevation access tunnel connecting EPO to the Guajes Tunnel
(planned to commence in mid-2025), will support lower cost, closer to the deposit drilling which will, in
turn, inform and derisk the feasibility study mine design. The exploration drift will also provide access to
the upper portion of EPO.
ADVANCED EXPLORATION DRILLING PROGRAM
Beyond the defined resource boundary to the north of EPO, mineralization encountered in drill hole
ML23-942 (6.14 gpt AuEq over 15.8 m and 4.04 gpt AuEq over 11.2 m; press release dated September
5, 2023) drilled during the 2023 program was the basis for an Advanced Exploration drilling program.
Six holes drilled in a north-south direction as part of the 2024 program have confirmed the mineralization
continuity along a northwest trend extending for over 400 m with a vertical extension exceeding 100 m.
Most of the mineralized intercepts in the northern part of EPO are located at the hanging wall of the
dikes, trapped at the contact between the limestones and the intrusive bodies that host most of the
mineralization at the Media Luna Cluster. The latter suggests that the dike contacts could correspond to
the main mineralization feeders.
Drill hole ML24-1017 (3.41 gpt AuEq over 8.3 m) confirms the vertical continuity of the mineralization at
the hanging-wall of the dikes. The multiple mineralized intercepts encountered in this area suggest the
potential for additional ore shoots that are yet to be tested.
Initial results from the 2024 drilling program support the addition of Inferred Resources to the north of
EPO with the year-end mineral reserve and resource update. Assuming the ability to delineate Inferred
Resources in this area in 2024, follow-up delineation drilling in 2025 will look to further upgrade
resources in this area. Given that the vertical continuity of the mineralization encountered is potentially
conducive to a long-hole mining method, the success of current and future drilling could support
additional mining fronts at EPO, which in turn could support mining beyond what was identified in the
prefeasibility study.

EPO GEOLOGY
The main host unit at EPO is the Morelos Formation, cut by an intrusive phase of the Media Luna
granodiorite and followed by multiple generations of late felsic dikes predominantly oriented northwest
and northeast. Finally, a dome and phreatomagmatic breccia event with an apparent north-south control
crosscuts the whole sequence.
EPO is located to the east of the major Cuajiote fault within a structural block characterized by multiple
second-order structures. These structures are recognized at surface and in drill core, and exhibit north-
south, north-northeast, and subordinate northwest orientations. The north-south oriented Copalillo and
Todos Santos faults control the main alteration-mineralization event. Early-stage calc-silicate alteration is
related to a proximal "aborted" skarn event containing anomalous molybdenum values and traces of Cu
and Au. The latter grades into CRD-style mineralization that is associated with the main Cu and Ag
mineralization event. Mineralizing fluids are believed to have originated from a deeper magmatic source,
younger than the Media Luna granodiorite stocks, which have not yet been identified at surface. A late
IS-epithermal mineralization event, related to the phreatomagmatic activity, increases the Au volume and
grade. Dikes and sills are deemed to have been previously emplaced along the same feeder structures
of the mineralization event and constitute traps for the mineralized bodies. Given that Au precipitates due
to the buffer exerted by the early stage calc-silicate alteration and sulfide mineralization, it occurs as free
Au and is dissociated from the early Cu event mainly related to chalcopyrite.
QA/QC AND QUALIFIED PERSON
Torex maintains an industry-standard analytical quality assurance and quality control ("QA/QC") 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. ("SGS") in Durango, and by SGS at Minera
Media Luna site facilities in 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 for EPO drilling is currently overseen by José Antonio San Vicente Díaz,
Chief Exploration Geologist for Minera Media Luna, S.A. de C.V. All samples reported have been
checked against Company and Lab standards, and blanks. No core duplicate samples are taken.
Sample preparation is carried out by BV at its facilities in Durango, Mexico and consists of crushing a 1
kg sample to >70% passing 2 mm followed by pulverisation of 500 g to >85% passing 75 μm. Gold is
analyzed at the BV facilities in Hermosillo, Mexico following internal analytical protocols (FA430) and
comprises a 30g fire assay with an atomic absorption finish. Samples yielding results >10 g/t Au are re-
assayed by fire assay with gravimetric finish (FA530-Au). Copper and silver analyses are completed at
the BV facilities in Vancouver, Canada as part of a multi-element geochemical analysis by an aqua regia
digestion with detection by ICPES/MS using BV internal analytical protocol AQ270. Overlimits for the
multi-element package are analyzed by internal protocol AQ374. Scientific and technical information

Notes to accompany the mineral resource table:
1. Mineral Resources were prepared in accordance with the CIM Definition Standards (May 2014) and the CIM MRMR Best Practice Guidelines
(November 2019).
2. Mineral resources are depleted above a mining surface or to the as-mined solids as of December 31, 2023.
3. Gold equivalent ("AuEq") of total mineral resources is established from combined contributions of the various deposits.
4. Mineral resources for all deposits are based on an underlying gold ("Au") price of US$1,650/oz, silver ("Ag") price of US$22/oz, and copper
("Cu") price of US$3.75/lb.
5. Mineral resources are inclusive of mineral reserves.
6. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
7. Numbers may not add due to rounding.
8. The estimate was prepared by Ms. Carolina Milla, P.Eng. (Alberta), Principal, Mineral Resources.
Notes to accompany Media Luna Underground mineral resources:
1. The effective date of the estimate is December 31, 2023.
2. Mineral resources for Media Luna Underground are reported above a 2.0 gpt AuEq cut-off grade.
3. Metallurgical recoveries at Media Luna Underground average 90% Au, 86% Ag, and 93% Cu.
4. The assumed mining method is from underground methods, using a combination of long-hole open stoping and mechanized cut-and-fill.
5. Media Luna Underground AuEq = Au (gpt) + (Ag (gpt) * 0.0127) + (Cu (%) * 1.6104), accounting for underlying metal prices and metallurgical
recoveries for Media Luna Underground.
Notes to accompany ELG Underground mineral resources:
1. The effective date of the estimate is December 31, 2023.
2. Mineral resources for ELG Underground are reported above a cut-off grade of 2.2 gpt AuEq.
3. Average metallurgical recoveries are 90% Au, 86% Ag, and 93% Cu, accounting for recoveries with planned copper concentrator.
4. The assumed mining method is underground cut and fill.
5. ELG Underground AuEq = Au (gpt) + (Ag (gpt) * 0.0127) + (Cu (%) * 1.6104), accounting for underlying metal prices and metallurgical
recoveries for ELG Underground.
Notes to accompany EPO Underground mineral resources:
1. The effective date of the estimate is December 31, 2023.
2. Mineral resources for EPO Underground are reported above a 2.0 gpt AuEq cut-off grade.
3. Metallurgical recoveries at EPO average 87% Au, 85% Ag, and 92% Cu.
4. The assumed mining method is from underground methods, using long-hole open stoping.
5. EPO Underground AuEq = Au (gpt) + (Ag (gpt) * 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 gpt 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 (gpt) + (Ag (gpt) * 0.0045) + (Cu (%) * 0.2627), accounting for underlying metal prices and metallurgical recoveries
for ELG Open Pit.
Figure 1: The resource expansion program at EPO confirms the continuity of the mineralization to the
north along a northwest corridor. Resource Delineation drilling in the southern portion of EPO indicates
the potential to upgrade Inferred Resources to Indicated Resources.
