Notes to Table:
- Gold equivalent (AuEq) Mineral Reserves and Resources take into
account respective metal prices and metallurgical recoveries for
gold, silver, and copper (see Table 3 and Table 5).
- Mineral Resources are reported inclusive of Mineral
Reserves.
- The reader is cautioned not to
misconstrue this tabulation as a Mineral Reserve or a Mineral
Resource statement. Tonnes, grades, and contained metal are shown
for comparison purposes only.
- Year-end Mineral Reserves and
Resources as well as year-over-year variance subject to
rounding.
Gold equivalent (“AuEq”) Mineral Reserves and
Mineral Resources take into account respective metal prices and
metallurgical recoveries for gold (“Au”), silver (“Ag”) and copper
(“Cu”) by deposit. Metals prices used to estimate Mineral Reserves
and Mineral Resources remain unchanged.
Jody Kuzenko, President & CEO of Torex,
stated:
“We are pleased with the results of the year-end
2022 Mineral Reserve & Resource estimate which further
highlights the geological excellence of our Morelos Property. On a
total asset AuEq basis, net of depletion, Measured & Indicated
Resources increased 567 koz (+8%) and Inferred Resources increased
41 koz (+2%). Prior to mine depletion of 511 koz AuEq, Measured
& Indicated Resources increased 1,078 koz (+16%).
“At Media Luna, an inaugural Measured Resource
of 473 koz AuEq at an average grade of 8.06 grams per tonne (“gpt”)
AuEq was declared. The Measured Resource is contained within three
separate zones of the deposit. Additionally, drilling was
successful in expanding Inferred Resources along the northern and
southern boundaries of the Media Luna deposit while inclusion of
outstanding results from the 2021 infill drilling program resulted
in additional Indicated Resources.
“The success at Media Luna was equally matched
by the success at EPO, with infill drilling delivering an inaugural
Indicated Resource of 671 koz AuEq at an average grade of 5.16 gpt
AuEq. Step-out drilling to the south and west of EPO was successful
in partially offsetting resources upgraded to the Inferred
category. Based on the updated resource estimate and potential for
additional resource growth, we are growing increasingly confident
about the prospect of EPO becoming an additional future source of
mill feed at the Morelos Complex, thereby even further unlocking
the economics of the Media Luna project.
“At the ELG Mine Complex, conversion of
resources to reserves, drilling success and model updates resulted
in more than 60% of Proven & Probable gold reserves processed
in 2022 being replaced. On an AuEq basis, additional laybacks in
the El Limón open pit added approximately 190 koz to Mineral
Reserves while expansion of the El Limón Sur open pit added
approximately 50 koz. Reserve gains in the producing Sub-Sill and
ELD deposits as well as initial reserves within the Sub-Sill South
and El Limón Sur Deep deposits offset a majority of ore mined from
the ELG Underground in 2022.”
Detailed breakdowns of Mineral Reserve and
Mineral Resource estimates can be found in Table 7 and Table 8 of
this press release. The detailed breakdowns include tonnes, grade
and contained metal estimates by metal as well as notes
accompanying the applicable Mineral Reserve and Resource
estimates.
PROVEN & PROBABLE MINERAL
RESERVES
Total Proven and Probable Mineral Reserves are
estimated at 4,947 koz AuEq at an average grade of 3.98 gpt AuEq,
representing a 3% decrease relative to year-end 2021 reserves of
5,123 koz AuEq at 3.90 gpt AuEq. Of the Proven & Probable
Reserves, 73% of the AuEq estimate is attributable to Au, 23% to
Cu, and 4% to Ag.

Limón pit added approximately 190 koz to reserves while drilling
success in the El Limón Sur pit added approximately 50 koz. In the
ELG Underground, reserves were once again added at the Sub-Sill and
ELD deposits while initial Mineral Reserves were declared at
Sub-Sill South and El Limón Sur Deep.

Underground have been updated to reflect anticipated Au, Ag, and Cu
recoveries once the copper and iron sulphide flotation circuits are
commissioned in late-2024 as part of the Media Luna Project.
Proven & Probable Reserves in the ELG
Underground are now based on an AuEq cut-off grade. Mineral
Reserves at Media Luna are unchanged.
MEASURED & INDICATED MINERAL
RESOURCES
Total Measured & Indicated Mineral Resources
are estimated at 7,468 koz at an average grade of 4.86 gpt AuEq,
representing an 8% increase relative to 6,901 koz AuEq at 4.60 gpt
AuEq at year-end 2021. Of the Measured & Indicated Resource,
68% of the AuEq estimate is attributable to Au, 26% to Cu, and 5%
to Ag.

Notes to Table:
- Gold equivalent Mineral Resources
take into account respective metal prices and metallurgical
recoveries for gold, silver, and copper (see Table 5).
- Measured & Indicated Resources inclusive of Mineral

- Ore mined (depletion) in 2022 on a

- Year-end Mineral Resources and
year-over-year variance (2022 versus 2021) subject to
rounding.
The decline in Measured & Indicated
Resources within the ELG Open Pit primarily reflects depletion. At
the ELG Underground, infill drilling was successful in more than
offsetting 110 koz AuEq of mine depletion.
Measured & Indicated Resources specific to
Media Luna increased 275 koz AuEq, driven by the benefit of
incorporating outstanding assay results from the 2021 infill
drilling program, results which were received post the cut-off date
for the year-end 2021 resource estimate. Additionally, infill
drilling targeting three separate zones within the Media Luna
deposit resulted in an inaugural Measured Resource of 473 koz AuEq
at an average grade of 8.06 gpt AuEq.
Infill drilling at EPO was successful in
establishing an inaugural Indicated Resource of 671 koz AuEq at an
average grade of 5.16 gpt AuEq. The higher-grade nature of the
Indicated Resource relative to the previous Inferred Resource at
EPO is due to higher grades encountered through the 2022 infill
drilling program, which in the area targeted led to a conversion
rate of 108% based on AuEq contained metal and 83% based on
tonnes.

At Media Luna, drilling targeting spatial gaps
in prior drilling was successful at adding Inferred Resources along
the northern and southern boundaries of the deposit. The success of
this program partially offset resources upgraded to the Indicated
category.
Drilling at the El Limón Sur open pit was
successful in expanding Inferred Mineral Resources within the upper
areas of the deposit while drilling within the ELG Underground
added to Inferred Resources. The additional Inferred Resources
helped offset a portion of resources upgraded to the Indicated
category during 2022.
Step-out drilling to the south and west of EPO
offset a portion of the Inferred Resources upgraded to the
Indicated category (671 koz AuEq). The EPO deposit remains open to
the north, south and west.
QUALITY ASSURANCE/QUALITY
CONTROL
Torex maintains an industry-standard analytical
quality assurance/quality control (QA/QC) and data verification
program to monitor laboratory performance and to ensure high
quality assay results. Results from this program confirm
reliability of the assay results. All sampling is conducted by
Torex Gold with analytical work for exploration programs at El
Limón Guajes performed by SGS de Mexico S.A. de C.V. (“SGS”) in
Durango, and by SGS in Nuevo Balsas, Mexico (each lab is
independent of the Company). Gold analyses comprise fire assays
with atomic absorption or gravimetric finish. External check assays
for QA/QC purposes are performed by ALS Chemex de Mexico S.A. de
C.V. (independent of the Company). The analytical QA/QC program at
El Limón Guajes is currently overseen by Carlo Nasi, Chief Mine
Geologist for Minera Media Luna, S.A. de C.V.
Torex has a sampling and analytical QA/QC
program in place that has been approved by Bureau Veritas
(“BV”) and is overseen by Nicolas Landon, Chief Exploration
Geologist for Minera Media Luna, S.A. de C.V. The program includes
5% each of Certified Reference Materials and Blanks; blind
duplicates are not included, but Torex evaluates the results of
internal BV laboratory duplicates. Torex uses an independent
laboratory to check selected assay samples and reference materials
and has retained a consultant to audit the QA/QC data for every
drill campaign at Media Luna.

CAUTIONARY NOTES ON FORWARD LOOKING
STATEMENTSThis press release contains "forward-looking
statements" and "forward-looking information" within the meaning of
applicable Canadian securities legislation. Forward-looking
information also includes, but is not limited to, statements about:
the potential for additional resource growth; the Company growing
increasingly confident about the prospect of EPO becoming an
additional future source of mill feed at the Morelos Complex,
thereby even further unlocking the economics of the Media Luna
project; the EPO deposit remains open to the north, south and west;
and the Company’s key strategic objectives to extend and optimize
production from the ELG Mining Complex, de-risk and advance Media
Luna to commercial production, build on ESG excellence, and to grow
through ongoing exploration across the entire Morelos Property.
Generally, forward-looking information can be identified by the use
of forward-looking terminology such as “strategy”, “focus”,
“potential” or variations of such words and phrases or statements
that certain actions, events or results “will”, or “is expected to"
occur. Forward-looking information is subject to known and unknown
risks, uncertainties and other factors that may cause the actual
results, level of activity, performance or achievements of the
Company to be materially different from those expressed or implied
by such forward-looking information, including, without limitation,
risks and uncertainties associated with: the ability to add mineral
resources, the ability to upgrade mineral resources categories of
mineral resources with greater confidence levels or to mineral
reserves; risks associated with mineral reserve and mineral
resource estimation; uncertainty involving skarn deposits; and
those risk factors identified in the Technical Report and the
Company’s annual information form and management’s discussion and
analysis or other unknown but potentially significant impacts.
Forward-looking information is based on the assumptions discussed
in the Technical Report and such other reasonable assumptions,
estimates, analysis and opinions of management made in light of its
experience and perception of trends, current conditions and
expected developments, and other factors that management believes
are relevant and reasonable in the circumstances at the date such
statements are made. Although the Company has attempted to identify
important factors that could cause actual results to differ
materially from those contained in the forward-looking information,
there may be other factors that cause results not to be as
anticipated. There can be no assurance that such information will
prove to be accurate, as actual results and future events could
differ materially from those anticipated in such information.
Accordingly, readers should not place undue reliance on
forward-looking information. The Company does not undertake to
update any forward-looking information, whether as a result of new
information or future events or otherwise, except as may be
required by applicable securities laws.

Notes to accompany Mineral Reserve table:1.
Mineral Reserves were developed in accordance with CIM (2014)
guidelines.2. Rounding may result in apparent summation differences
between tonnes, grade, and contained metal content. Surface
Stockpile Mineral Reserves are estimated using production and
survey data and apply the same gold equivalent (“AuEq”) formula as
ELG Open Pits.3. AuEq of Total Reserves is established from
combined contributions of the various deposits.4. The qualified
person for the Mineral Reserve estimate is Johannes (Gertjan)
Bekkers, P. Eng., VP of Mines Technical Services.5. The qualified
person is not aware of mining, metallurgical, infrastructure,
permitting, or other factors that materially affect the Mineral
Reserve estimates.Notes to accompany the Media Luna Underground
