Torex Gold Resources Inc. (the "Company" or "Torex") (TSX:TXG) is pleased to announce the results of the first portion of its drilling program under the 'El Limon Sill'. Highlighted intercepts from the El Limon Sill exploration program include 317.8 g/t Au over 3.4m in borehole SST-01, 230.7 g/t Au over 2.4m in borehole SST-19, 19.6 g/t Au over 9.6m in borehole ST-25, 22.6 g/t Au over 13.3m in borehole SST-27 and 83.3 g/t Au over 4.3m in borehole SST-34.
Fred Stanford, President & CEO of Torex stated: "Today's high grade, under the sill, exploration results provide an exceptional start to the new year, and an equally exceptional opportunity to add significant resources in close proximity to existing operations. 3.4 meters of 10 ounces per tonne tends to bring a smile and an imperative to move quickly. The under the sill area can be accessed by a 600 meter ramp from the El Limon Access Road. This ramp has been collared and is already advanced more than 110 meters toward the target area. These results and the success rate of our exploration programs confirm our belief in the potential for mining in this area for generations to come. The results also open the possibility of finding additional 'sill type' targets in areas close to the processing plant. Further exploration of deeper targets will be conducted from the bottom of the ramp, once it is completed later this year." He added; "An updated resource estimate for the 'under the sill' area is expected in Q2/17."

The Company's diamond drilling program is focused on the exploration of a high-grade mineralized area located between the El Limon and El Limon Sur ore deposits and under the El Limon Sill. Four exploration holes drilled in 2011 intercepted a new skarn zone with high-grade gold mineralization developed underneath the intrusive that underlies the El Limon ore deposit. 34 holes totaling 7,727 meters covering an area of 350 meters by 150 meters were completed between September and December 2016 to explore the continuity and the mineral potential of this system. The assays of 23 holes have been reported to date with positive results, confirming the continuity of the skarn zone and the high grade mineralization. The current information from the drill program indicates that the system remains open down-dip to the West and North and up-dip to the East. Southernmost drill hole results are pending. The mineralized areas are located between 30 and 270 meters below the surface.
The El Limon Sill area occurs in the Mesozoic carbonate-rich Morelos Platform, which has been intruded by Paleocene granodiorite stocks, sills and dikes. Skarn-hosted gold mineralization is developed along the contacts of the intrusive rocks and the enclosing carbonate-rich sedimentary rocks. Structurally, the El Limon 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 considered to be potential feeders for the mineralization. At the El Limon Sill area, several skarn zones were identified along the contacts of the carbonate rich sediments and marbles of the Cuautla and Morelos formations and sills fingering out from the main granodiorite stock. Sedimentary rocks and their contact with the granodiorite sills, dip southwest at approximately 30º. Extensive skarn alteration and metal deposition exhibit the same dip. Individual high grade ore zones have been identified in the different skarn horizons and also within the same skarn zone. Individual ore zones vary in strike length from approximately 50 meters up to 200 meters. Apparent widths vary from 2 meters to 27 meters.
Mineralization at the El Limon Sill area is primarily gold, associated with variable contents of silver and copper. Mineralization is hosted in pyroxene-garnet marble related exoskarn, in granodiorite related endoskarn and locally, in narrow lenses of massive sulfides, that have been affected by a late stage retrograde alteration, characterized by amphiboles, chlorite, calcite ± quartz ± epidote. Gold occurs in low and high sulfidized skarns, while silver and copper mineralization is primarily determined by the degree of sulfidation of the host skarn.
QA/QC and Qualified Person
At the Morelos Gold Project, all of the El Limon 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 SGS sample preparation laboratory in Durango, Mexico. The gold analyses (fire assay with an atomic absorption or gravimetric finish) are completed at SGS analytical laboratory in Durango, Mexico and multi-element geochemical analyses are Copper Sequential Leaching are 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 reference 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 absolute accuracy at anomalous to near cut-off grades is measured and 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.
