At the Creston Mascota satellite operation 2.1 M tonnes of ore were processed (5,790 tpd) at a grade of 1.12 g/t Au, to produce 47,296 Oz Au. At La India 5.84 M tonnes of ore were processed (15,948 tpd) @ 0.81 g/t Au, to produce 115,162 Oz Au.
• Primero Mining Corp. halted production at its San Dimas mine in Durango due to unionized workers initiating a strike action. “Primero’s key focus in these negotiations has been to better align the short-term bonus structure with overall mine-site performance and profitability, and to move the labour force onto a more continuous shift cycle to improve productivity.”

ON FINANCING

• Source Exploration Corp. arranged a non-brokered private placement for gross proceeds of $1.85 M, to replace the second tranche of the previously announced non-brokered private placement.

ON RESOURCES AND DEVELOPMENT.

• Torex Gold Resources Inc. released results from the first round of its step out drilling program for its Sub-Sill target at its Limon-Guajes operations in Guerrero. High grade intercepts (core length) in skarn mineralization include: 2.9 m @ 33.7 g/t Au, 0.3% Cu; 7.4 m @ 23.0 g/t Au, 1.2% Cu; 16 m @ 19.4 g/t Au, 1.0% Cu; 4.1 m @ 23.2 g/t Au, 1.2% Cu; 15.5 m @ 14.9 g/t Au, nil Cu; 5.8 m @ 23.9 g/t Au, 0.1% Cu; 3.9 m @ 112.7 g/t Au, 1.3% Cu; 10.6 m @ 9.1 g/t Au, 3.4% Cu. The 34 hole, 7,727 meter program tested an area roughly 350 m by 150 m, with the system remaining open in several directions. “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.”
• Mag Silver Corp. reported results for 13 exploration and infill holes that extend the high-grade mineralization on the Deep Zones of the Valdecañas vein system on their Minera Juanicipio JV with Fresnillo PLC in Zacatecas. The Deep Zone West has now been traced over 550 m, with vein widths from 11.4 m to 26.5 m and a minimum vertical height of 200 m. The Deep Zone East is continuous over 750 m, 5.6 m to 29.9 m in width, with up to 300 m of vertical extent. Underground development and mining infrastructure continue to be progressed, the ramp reached the uppermost part of the Valdecañas vein in December 2016 and footwall development has commenced.
