ON MEXICO ISSUES

  • First Majestic Silver’s, El Pilon mine in San Martin de Bolaños, Jalisco, suffered a robbery, with 57 silver bars (25 Kg each) extracted and transported in company’s trucks. One of the vehicles was recovered nearby, with part of the bounty.

ON EXPLORATION

  • Arian Silver Corp. presented sample results from its La Africana project in Zacatecas. Assay results from 11 grab samples, of which seven are between 196 and 842 g/t Ag, and up to 4.9% Zn.
  • Sierra Metals Inc. announced high-grade silver intercepts in the Santa Rosa de Lima complex at its Cusi mine in Chihuahua. The 15,000 m program has an 80% advance to date (10,200 m). True width (TW) Intercepts include 3.2 m 332 g/t Ag; 2.5 m @ 200 g/t Ag; 1.5 m @ 292 g/t Ag; 1.5 m @ 1,152 g/t Ag; 3.1 m @ 1,037 g/t Ag, with up to 5.2% Pb and 3.5% Zn. The Santa Rosa de Lima complex has an anticipated extension of 12 km within Sierra Metals concessions; with mineralization located 100 m below the surface, and occasionally observed at the intersections of other veins. The drilling covers about one kilometer of the structure.
  • Source Exploration Corp. commenced a diamond drill program for the Las Minas copper-gold skarn project in Veracruz. An initial 2,000 – 3,000 metres infill and step out at the El Dorado – Juan Bran zone, with the aim of completing a maiden NI-43-10 resource estimate on early 2017. Further mapping, trenching and sampling will be carried out on the Pueblo Nuevo concession. Previous drilling has outlined a mineralized zone 420 m in width, 6.0 to 82 m in thickness, and extending more than 600 m in depth; the zone remains open on strike and down-dip.
  • San Marco Resources Inc. announced that soil sampling results from its Chunibas property in Sonora have confirmed a 600 x 800 m target. Drilling is expected to probe deeper and on-strike mineralized zones.
  • Kootenay Silver Inc. informed Pan American Silver Corp. is to proceed in 2017 with a US$2.0 M budget on La Negra property in Sonora, with 6,500 m of diamond drilling, geological mapping and reconnaissance work to define additional prospective targets proximal to La Negra within the Promontorio project.
  • Silver One Resource Inc. completed geochemical soil surveys at its Peñasco Quemado and La Frazada properties in Sonora and Nayarit respectively. At Peñasco Quemado a 3,000 m long, 300 m wide linear anomaly overlaps with the area of the current resource, with high manganese (0.17% – 1.1%) and barium (0.15% – 0.88%), and more localized zinc (400 – 3,500 ppm) and lead (135 – 800 ppm); a second anomaly 2,000 m long by 1,000 m wide is a new target. The survey consisted of 1,925 soil samples, XRF assayed, with 320 quality control samples sent for assaying to a US lab, with a very good correlation. At La Frazada the 222 soil samples were not that successful to highlight some of the veins, the reason forwarded being the probable leaching of metals in the subtropical environment.
