ON EXPLORATION

  • SilverCrest Metals Inc. disclosed results from initial metallurgical sampling of mineralization from its Las Chispas property in Sonora. These results show that Las Chispas mineralization appears to be amenable to standard cyanidation processing, with average recoveries of 98.9% Au, 86.6% Ag. Nineteen core samples were combined into three bulk composites, with partly oxidized and non-oxidized material. Further metallurgical test work is to be completed after the announcement of a maiden resource in Q1 2018.
  • Auxico Resources Canada Inc. released metallurgical results from a 2 Kg metallurgical sample from a volcanic breccia in the footwall of the Campanillas mine, at its Zamora property in Sinaloa. The test returned 13.8% Au, 8.6% Ag recovery by gravity, 67.8% Au, 89.1% recovery by flotation, for total recoveries of 71.6% Au, 92.9% Ag.
  • Defiance Silver Corp. commenced a two-rigs phase II 5,000 m drill core program targeting new high-grade silver shoots along 900 m of the Veta Grande vein, SE from the San Acacio deposit in Zacatecas.
  • Golden Goliath Resources Ltd. received a report on its San Timoteo property in Chihuahua. The report stresses the presence of several strong systems of mineralized structures with potential for bonanza zones and a deeper Cu-Au porphyry system. Known zones within the Level 5 of the San Timoteo vein contain a 78 m long shoot @ 0.6 g/t Au, 68 g/t Ag and a 32 m long shoot @ 0.3 g/t Au, 212 g/t Ag.
  • Riverside Resources Inc. updated on exploration work in progress at its Glor property in Sonora, alongside its partner Centerra Gold Inc.. The work is focusing on the central part of the property, where samples of up to 14 g/t Au have been collected, with a detailed ground magnetic survey covering 210 hectares with 80 line-kilometers, 14 line-kilometers on an induced polarization survey, and an 850 sample soil program.
  • Prospero Silver Corp. received all necessary permits to carry a first-pass drill program at Bermudez, in Chihuahua. Prospero can now proceed with a drilling campaign funded by Fortuna Silver Mines Inc. to test a low sulfidation epithermal vein system exposed over a 2.5 km by 50-100 m area. Anomalous Au, Ag, Ba and Zn, along with the quartz vein textures support the interpretation of this being a shallow zone in the epithermal system.
  • Minaurum Gold Inc. released results from the first five holes (1,342 m) at its Alamos project in Sonora. Relevant intercepts on the Promontorio vein: 20.15 m @ 154 g/t Ag, 0.23 g/t Au, 0.5% Cu, 2.3% Pb, 6.8% Zn; 8.50 m @ 81 g/t Ag, 0.13 g/t Au, 0.1% Cu, 3.2% Pb, 2.7% Zn; 3.15 M @ 322 g/t Ag, 0.28 g/t Au, 0.5% Cu, 1.6% Pb, 3.3% Zn. At the Blind Vein/Southern Nueva Europa target an interval of 0.25 m @ 8 g/t Ag, 0.9% Pb, 2.4% Zn validated the idea of blind veins on the area. At the Minas Nuevas target the 17.65 m @ 96 g/t Ag and 13.05 m @ 54 g/t Ag intercepts confirm the potential for bulk-tonnage orebodies.

ON MINING

  • Starcore International Mines Ltd. is changing its senior management and sales personnel at the Altiplano processing plant in Matehuala, San Luis Potosi.

Length of hole intercepts include 4.4 m @ 7.4% Zn, 5.6% Pb, 0.12% Cu, 18 ppm Ag; 2.40 m @ 4.3% Zn, 3.4% Pb, 15 g/t Ag; 9.30 m @ 7.9% Zn, 3.4% Pb, 0.4% Cu, 32 g/t Ag; 2.50 m @ 8.9% Zn, 5.6% Pb, 1.0% Cu, 27 g/t Ag; 7.40 m @ 7.8% Zn, 5.9% Pb, 0.11% Cu, 22 g/t Ag: 3.85 m @ 5.3% Zn, 6.1% Pb, 0.13% Cu, 18 g/t Ag; 3.40 m @ 6.8% Zn, 7.1% Pb, 0.61% Cu, 23 g/t Ag; 2.50 m @ 8.3% 5.7% Pb, 0.24% Cu, 24 g/t Ag; 6.65 m @ 16.5% Zn, 2.3% Pb, 0.51% Cu, 107 g/t Ag. Substantial widths of massive and banded sulfide were hit on most holes, with all mineralization fresh and non-oxidized. Azure has submitted an application for a resource drill-out program covering an area of 1,400 m x 400 m, and a wider exploration program. Note by editor.- This property was subject to a non-conclusive debate back in the 1980’s regarding its origin, either a volcanogenic massive sulfide  (would be the first in Sonora) or a skarn originated by felsic dikes intruding intracaldera sediments, including the hosting thin layered limestone. It’s going to be interesting what Azure’s take on the deposit’s origin is.
  • Aztec Minerals Corp. released assay results from sampling on two trenches at the Jasper prospect on the Cervantes property in Sonora.
