TOREX SUB-SILL GROWTH POTENTIAL CONFIRMED BY STEP-OUT DRILLING

TORONTO, Ontario, September 19, 2017 – Torex Gold Resources Inc. (the “Company” or “Torex”) (TSX:TXG) is pleased to announce

high grade intercepts in the step-out drilling in the quadrant to the northwest of the current Sub-Sill resource area, associat ed with its El

Limon-Guajes Mine (ELG) in Southwest Mexico. Highlighted intercepts from this step-out program include 41.4 g/t Au over 19.3m in a

40-meter step-out to the north, in borehole SST-71. To the northwest, in a 130-meter step-out, borehole SST-91 intercepted 35.9m of

5.7 g/t Au , including 3.5m of 32.2 g/t Au, and another 3.5m of 14.1 g/t Au . In a more westerly direction, in a 240-meter step-out,

borehole SST-88 intercepted 11.6 g/t Au over 3.6 meters. The Company also announced results of an additional 15 holes of the in-fill

program that will contribute to the next resource estimate, including 32.2 g/t Au over 29.3m in borehole SST-72.

Fred Stanford, President & CEO of Torex stated: “The current Sub-Sill resource estimate area is approximately 250m x 150m. The high

grade results from the step-out drilling in the quadrant to the NW of the resource area, including a 240m step-out borehole, ce rtainly

confirm the potential for additional resources in this direction. Step-out drilling near the resource in the NE quadrant inter cepted

granodiorite in the target area. Longer range step-out drilling is planned to determine whether the intrusive rocks continue in this direction,

or if skarn exists on the ‘other side’ of a localized intrusion. To the SW, several boreholes have been drilled and we are wai ting for

assays. To the SE, we will wait until after the rainy season to drill in this area.” He added – “These are exciting times for the Sub-Sill

program, we look forward to the upcoming update to the resource and the subsequent mine plan to convert those resources to reserves.

Both are expected before year end 2017. In the meantime, step-out drilling will continue, as will underground mining activitie s to install

infrastructure and extract mineral for processing.”

The Company’s Sub-Sill in-fill diamond drilling program comprises a total of 47 holes (7,295m). The purpose of the program, at a 17.5m

x 17.5m drill pattern, is to upgrade 1,000,000 tonnes, over an ar ea of 250m x 150m, to the Indicated category, which will suppo rt the

development of a mine plan. The positive results to date confirm the geological continuity of the skarn zones as well as the c ontinuity

and the strength of the mineralization system. The results to-date of the drilling program also demonstrates the existence and continuity

of other mantos underneath the main resource zone, that were not included in the resource estimate due to the insufficient drilling at the

time.

The Sub-Sill area is located between the El Limon and El Limon Sur ore deposits and under the El Limon Sill. The Sub-Sill area occurs

in the Mesozoic carbonate-rich Morelos Pla tform, which has been intruded by Paleocene granodiorite stocks, sills and dikes. Ska rn-

hosted gold mineralization is developed alo ng the contacts of the intrusive rocks and the enclosing carbonat e-rich sedimentary rocks.

Structurally, the Sub-Sill target area as well as El Limon and El Limon Sur ore deposits are hosted in a graben bounded by La Flaca fault

to the west and the Antena fault to the east, and both are cons idered to be potential feeders for the mineralization. At the Su b-Sill area,

several skarn zones have been identified along the contacts of the carbonate rich sediments and marbles of the Cuautla and More los

formations and sills fingering out from granodiorite stocks. High grade gold mineralization has been intercepted in all the different skarn

horizons. Within the skarn zones individual shoots of mineralization vary in strike length from approximately 50 meters up to 200 meters,

with apparent thickness varying from 2 meters to 36 meters.

Mineralization of the Sub-Sill area is primarily gold, with variable amounts of silver and copper. Gold occurs in low and high sulfidized

pyrrhotite rich skarns, while silver and copper mineralization is primarily determined by the degree of sulfidation of the host skarn.

Mineralization is strongly associated with a late stage retrograde alteration characterized by amphiboles, chlorite, calcite ± quartz ±

epidote, affecting pyroxene-garnet marble related exoskarn and granodiorite porphyry related endoskarn. Locally mineralization occurs

in narrow lenses of massive sulfides.

QA/QC and Qualified Person

At the Morelos Gold Project, all of the Sub-Sill target analytical work is performed by SGS de Mexico S.A. de C.V. ("SGS") in Durango,

Mexico and at SGS Mineral Services in Vancouver, British Columbia, Canada and ALS Chemex de Mexico S.A. de C.V.

Sample preparation is done at the SGS sample preparation laboratory in Durango, Mexico. The gold analysis (fire assay with an atomic

absorption or gravimetric finish) is completed at the SGS analytic al laboratory in Durango, Mexico and multi-element geochemica l

analysis and Copper Sequential Leaching is completed at their analytical facilities in Vancouver, British Columbia, Canada. Check assays

samples are analyzed at ALS Chemex Vancouver, BC, Canada. SGS and ALS Chemex, are independent of the Company. 

The Company has a Quality Assurance/Quality Control (“QA/QC”) program in place that includes 5% of each of the certified refere nce

materials, blanks and field duplicates. 10% of pulp samples are analyzed at a second laboratory as part of the QA/QC program to ensure

the batch to batch relative bias remains constant and that absol ute accuracy at anomalous to near cut-off grades is measured an d

acceptable. The QA/QC program as designed, has been approved by Bureau Veritas and is currently overseen by Carlo Nasi, Chief Mine

Geologist for the Morelos Gold Project.

The scientific and technical data contained in this news release pertaining to the Morelos Project has been reviewed and approv ed by

Mr. Mark P. Hertel as a Qualified Person under NI 43-101. Mr. Hertel is a Registered Member of the Society for Mining, Metallurgy &

Exploration, has experience relevant to the style of mineralization under consideration and is an independent consultant. Mr. Hertel has
