TECHNICAL REPORT CONFIRMS TOREX STATUS

AS A PRODUCER IN THE LOWEST COST QUARTILE

TORONTO, Ontario, September 4, 2018 – Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX:TXG) announces completion of an

updated Technical Report (TR) including a life of mine plan (LOM) for its producing El Limon Guajes ( ELG) Mines, that has increased

average annual gold production to 430,000 ounces per year, from 2019 to 2023. The TR also contains an updated Media Luna Preliminary

Economic Assessment (PEA), with an after -tax NPV (5%) of $582M, and an after -tax IRR of 27%. For purposes of illustration, the TR

includes a Media Luna design utilizing a conceptual new underground mining tech nology that Torex is developing. The new technology,

called the Muckahi Mining System (Muckahi), shows the potential to increase the Media Luna Project, NPV by $197M. If proven, the Muckahi

technology could be applicable to many other underground deposits.

Fred Stanford, President and CEO of Torex stated: “With the ELG, ramp -up to steady state nearing completion, this TR incorporates the

ramp-up learnings and illustrates that ELG is an asset that produces in the lowest quartile of all in sustaining costs per ounce. The TR also

lays out the ground work for growth through the ELG Underground (ELG UG) mine and Media Luna deposit, and through the advancement

of the conceptual Muckahi technology.

The updated Media Luna PEA delivers a healthy after-tax IRR of 27%, and an NPV (5%) of $582M. The CAPEX estimate is similar to the

2015 estimate, with costs updated to reflect the changes in design and three years of inflation. Additional metallurgical test work is underway

with the intention of demonstrati ng that metal recoveries can be increased. Infill drilling is ongoing for this project , with the objective of

upgrading 1.85M of the 7.4M Inferred Au Eq. ounces (25%), to the Indicated confidence category. We look forward to the completion of this

infill drilling and the advancement to the next levels of technical studies.

As expected, the Muckahi Mining System illustrates a potential for material improvement over conventional mining technologies. Using

Media Luna as a demonstration example, the study indicates that utilizing Muckahi produces an improvement of 19% in after-tax IRR from

27% to 46 %. (30% less underground mining capital, 20% less mine operating cost, and 60% reduction in time to a chieve commercial

production.) After many years of thought and design effort, the Muckahi Mining System is now shifting to the underground testing phase.

Manufacturing of the first of the prototype machines is underway, testing underground is scheduled to commence in Q1/19. We look forward

to having a proof of concept before the Media Luna feasibility study work requires a commitment to mining method. A technical session to

review the technology is scheduled for September 17th, 2018, between 10 am and 2 pm (ET). Please contact Gabriela Sanchez for invitation

details.

In conclusion, producing the TR has been a significant undertaking for a dedicated team. I thank them for grinding through the details and

illustrating the potential of Torex through the ELG Open Pits, ELG Underground, Media Luna, the Muckahi technology, and other Morelos

Property exploration targets. We look forward to the resetting of financial models and having many more investors join us as we create

value from these assets.”

The supporting Technical Report for the Company’s 100% owne d Morelos Property in Southwest Mexico, entitled “NI 43-101 Technical

Report ELG Mine Complex Life of Mine Plan and Media Luna Preliminary Economic Assessment”, which has an effective date of March 31,

2018, has been filed with SEDAR and posted on the Company’s website.

A preliminary economic assessment should not be considered a prefeasibility study or feasibility study, as the economics and technical

viability of the Media Luna Project have not been demonstrated at this time. The Media Luna PEA is prelim inary in nature and includes

inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would

enable them to be categorized as mineral reserves. It cannot be assumed that all or any part of the inferred mineral resources will ever be

upgraded to a higher category. Furthermore, there is no certainty that the conclusions or results as reported in the Media Luna PEA will be

realized. Mineral resources that are not mineral reserves do not do not have demonstrated economic viability. The Media Luna PEA 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.

CAUTIONARY NOTES

PRELIMINARY ECONOMIC ASSESSMENT

A preliminary economic assessment should not be considered a prefeasibility study or feasibility study, as the economics and technical viability of t he

Media Luna Project have not been demonstrated at this time. The Media Luna PEA is preliminary in nature and includes i nferred mineral resources that

are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral

reserves. It cannot be assumed that all or any part of the inferred mineral resources will ever be upgraded to a higher category. Furthermore, there is no

certainty that the conclusions or results as reported in the Media Luna PEA will be realized. Mineral resources that are not mineral reserves do not do not

have demonstrated economic viability.

The Media Luna PEA 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 TR. Aspects of Muckahi

mining equipment are currently in the design stage. The mine design, equipment performance and cost estimations are conceptual in nature, and do not

demonstrate technical or economic viability. The approximate timeframe to develop and test the concept would be approximat ely two years for the mine

development activities and up to five years for the mine production activities. Further studies would be required to verify the viability of Muckahi. Muckahi

is not intended as a “trade off study” but is shown to merely demonst rate the potential benefits Muckahi may have using the Media Luna deposit as an

example. It includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that

would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral

resources that are not mineral reserves do not have demonstrated economic viability.

FORWARD LOOKING STATEMENTS

This press release contains “forward- looking information” and “forward- looking statements” within the meaning of applicable Canadian securities

legislation. Forward-looking information includes, without limitation, information with respect to proposed expl oration and development activities and their

timing, the results set out in the TR including the Media Luna PEA, including, as applicable, the resource estimates , reserve estimates and potential

production, operating costs, total cash costs and AISC and other expenses and other economic parameters , estimated recoveries, expected mine life or

project life, estimated payback period, net present values, and earnings before interest, depreciation and amortization, the future price of gold, government

regulations and permitting timelines, requirements for additional capital, environmental risks, and general business and economic conditions, the expected

benefits and cost savings from the operation of the SART plan, the expected ramp- up of ELG to steady state full production, the potential growth of the

ELG UG mine, plans to complete additional metallurgical testing on the Media Luna mineralized material to demonstrate potential for improved recoveries,

plans to complete an infill drilling program and a feasibility study of the Media Luna Project, the potential to upgrade the mineral resources of the Media

Luna Project, the potential of the Muckahi mining system and possible application to other underground deposits, plans to com plete the manufacture of

prototypes for Muckahi and timing on the underground testing of the prototypes . Generally, forward- looking information can be identified by the use of

terminology such as “plans”, “expects”, “estimates”, “intends”, “potential”, or variations of such words, or statements that certain actions, events or results

“can”, “may”, “would”, “will”, or “will be taken”, “occur” or “be achieved”. Forward-looking information is subject to known and unknown risks, uncertainties

and other factors that may cause the Company’s actual results, l evel of activity, performance or achievements to be materially different from those

expressed or implied by such forward- looking information, including, without limitation, forward- looking statements and assumptions pertaining to the

following: risks associated with completing the ramp up of the operations to steady -state, risk associated with skarn deposits including grade variability,

fluctuation in gold and other metal prices, commodity price risk, currency exchange rate fluctuations, risk that expected benefits of SART plant will not be

realized, risk of illegal blockades impacting access to the ELG Mine Complex and the Media Luna Project or to supplies and services , uncertainty as a

result of the preliminary nature of the PEA and the Company’s ability t o realize the results of the PEA , uncertainty regarding the inclusion of inferred

mineral resources in the mineral resource estimate and the Company’s ability to upgrade the inferred mineral resources to a higher category, uncertainty

regarding the ability to convert any part of the mineral resource into mineral reserves , uncertainty involving resource estimates and the ability to extract

those resources economically, or at all , uncertainty involving drilling programs and the Company’s ability to expand and upgrade existing resource

estimates, the regulatory process and actions, the success of the Muckahi mining system, ability to finance the Media Luna Project on reasonable terms,

and those risk factors identified in the TR and the Company’s annual information form and management’s discussion and analysis. Forward- looking

information are based on the assumptions discussed in the TR 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 beli eves are

relevant and reasonable in the circumstances at the date such statements are made. Although the Company has attempted to i dentify important factors
