  • No relevant news.


  • Kootenay Silver Inc., reported exploration results from its Malé project in Sonora. Prospecting on the property has outlined several zones of anomalous Au mineralization. “Malé is a granitic-hosted gold dominant polymetallic vein and vein stockwork system covering an area of 1500 x 1500 meters with numerous showings highly anomalous in gold that have significant potential for both high grade vein as well as bulk tonnage stockwork deposits. Mineralization occurs as narrow veins, veinlets and stockworks of quartz with or without sulphides within structures projecting in a dominant northeast trend and a secondary northwest trend”. 30 samples out of 426 have returned values > 10 g/t Au with peaks of 260g/t Au, 85.5 g/t Au, 81.2 g/t Au, and 53.4 g/t Au. 64% of the samples returned values > 0.1 g/t Au, 47% > 0.5 g/t Au, 36% > 1 g/t Au, and 16% > 5 g/t Au. Ag values are irregular, with 21 samples returning > 100 g/t Ag. Kootenay geologists are mapping and sampling the entire property to generate drill targets.
  • Silver Viper Minerals Corp., announced that a camp and drill pad construction is underway on its La Virginia project in Sonora. The company plans to start an initial drill program of 5,000m on the main trend and two parallel trends within El Rubi-Esperanza group of concessions.
  • Sable Resources, presented results from drillholes M-DDH-18-07 and M-DDH-18-08 at its Margarita project in Chihuahua. Hole M-DDH-18-07 intercepted 3.6m of 417 g/t Ag Eq, including 1.0m of 707 g/t Ag Eq. Hole M-DDH-18-08 intercepted 14.05m of 461.4 g/t Ag Eq, including 2m of 859.5 g/t Ag Eq. This hole also contains Au values up to 3 g/t coincident with significant Zn and Pb values of 4.5% and 2.4% respectively. “The 14m intercept in drillhole M-DDH-18-08 represents our widest intersection to date with consistent average grades in excess of 400 grams per tonne silver equivalent. Sable now has five holes into the Margarita structure with a weighted average grade of 420g/t Ag Eq over an average width of 8.6m, and a confirmed strike length of 500m down to 80m depth from surface”.
  • VVC Exploration Corporation, announced drill results from its Samalayuca project in Chihuahua. The drill holes, which tested a 200-meter section of a 350-meter strike length zone, all intersected near surface, copper mineralization. Highlights results are in hole SC18-28 with 31.8m of 0.38% Cu, hole SC18-29 with 18m of 0.31% Cu and 4m of 0.97% Cu, hole SC18-30 with 53m of 0.36% Cu, and hole SC18-32 with 6m of 0.46% Cu.
  • Goldplay Exploration Ltd., released sampling results on historical drill core from its San Marcial project in Sinaloa. Significant results are 19.5m of 157 g/t Ag, including 1.5m of 1,285 g/t Ag in hole SM10-22.
  • Oroco Resources Corp., announced the acquisition of historical technical information and data related to its Santo Tomas deposit in Sinaloa. The data consist of drill hole assays and associated interpreted sections, drilling, composite and digital models and reports from 1992 to 2011. “As payment for the information and data, Oroco will issue, subject to TSX Venture Exchange approval, 500,000 common shares of Oroco and pay US$500,000 by way of three payments ofUS$50,000 each and a final payment of US$350,000, all to be made over a period of no more than three years, depending on the Company’s progress in assembling the Santo Tomas concessions”.


  • Americas Silver Corporation, announced Q2 2018 results from its Cosala operations in Sinaloa. The company milled 138,708 tonnes of 42 g/t Ag, 3.6%Zn, and 1.4% Pb to produce 94.2K OZ Ag, 8.75 M Lb Zn, and 3M Lb Pb. Metallurgical recoveries for Ag, Zn, and Pb are 49.9%, 78.9% and 70.2% respectively.
  • First Majestic Silver Corp., released Q2 2018 results from their Mexican operations. Figures for the seven producing mines are as follow:

“Total Q2 production increased 32%, compared to Q1, and consisted of 2.75 M Oz Ag, 25.4K Oz Au, 3.9M Lb Pb, and 1.38 M Lb Zn, to a new record of 5.1M OZ Ag Eq. The increase in production was primarily due to the addition of the San Dimas mine, which contributed 52 days of production during the quarter, producing 809K Oz Ag and 11.3K Oz Au, or 1.7M Oz Ag Eq. The increase in production was partially offset by decreases of 28% and 26% in Ag Eq production at La Encantada and Del Toro, respectively”.
