ON MEXICO ISSUES

  • No Relevant News.

ON EXPLORATION

  • Southern Silver Exploration Corp. disclosed exploration work on its Creston del Oro, Biznagas and Los Lenchos claims, which are contiguous to its Cerro Las Minitas property in Durango. Over 1400 rock chip and float samples have been collected, revealing a NW-SE corridor greater than 12 km in length, anomalous in precious metals and pathfinder elements. Targeting for an early 2018 RC drill campaign is to base on the multiple distinct clusters and trends seen.
  • Discovery Metals Corp. released results from 32 channel samples at its Puerto Rico project in Coahuila. The samples were collected on the southern part of the project, from the Puerto Rico, San Jose and Zaragoza mines, in manto style mineralization, as well as high-angle breccias, fracture zones and chimney features. Results include 0.8 m @ 202 g/t Ag, 22.3% Pb, 0.7% Zn, 0.16% Cu; 2.0 m @ 242 g/t Ag, 25.2% Pb, 6.3% Zn, 0.19% Cu; 3.5 m @ 506 g/t Ag, 3.5% Pb, 21.9% Zn, 0.11% Cu at Zaragoza; 10.5 m @ 25 g/t Ag, 1.6% Pb, 18% Zn, 0.15% Cu; 4.0 m @ 519 g/t Ag, 29.7% Pb, 17.3% Zn, 0.44% Cu; 3.0 m @ 1,480 g/t Ag, 31.9% Pb, 0.1% Zn, 0.41% Cu at San Jose; and 4.0 m @ 230 g/t Ag, 15.0% Pb, 26.3% Zn; 1.5 m @ 316 g/t Ag, 23.0% Pb, 15.0% Zn; 5.0 m @ 25 g/t Ag, 1.8% Pb, 31.1% Zn; 6.0 m @ 615 g/t Ag, 20.8% Pb, 24.3% Zn; 1.6 m @ 477 g/t Ag, 11.8% Pb, 2.4% Zn, 11.2% Cu at Puerto Rico.
  • Discovery Metals Corp. released panel and channel sampling results from its La Kika project in Coahuila. Numerous prospect pits are scattered over a 200 by 200 m area, showing high-grade Ag-Pb-Zn carbonate replacement mineralization as subhorizontal mantos and subvertical chimney-like structures with massive oxides of Zn-Pb-Ag-Cu. Results include 0.7 m @ 600 g/t Ag, 30.1% Pb, 8.3% Zn, 0.44% Cu; 0.5 x 1.0 m panel @ 35.5% Zn, 1.2% Cu; 1.0 x 0.5 m panel @ 160 g/t Ag, 10.0% Pb, 16.7% Zn, 0.24% Cu; 0.6 m @ 258 g/t Ag, 11.2% Pb, 12.4% Zn; 1.0 x 0.5 m panel @ 420 g/t Ag, 18.9% Pb, 1.2% Zn.
  • Consolidated Zn Ltd. announced results of first pass rock chip sampling at the Alfonsitos prospect, 2.5 km NW from its Plomosas mine in Chihuahua. Grades of up to 18.5% and 24.3% Zn+Pb were obtained from workings and outcrops respectively. Alfonsitos is the first of several prospects identified by reconnaissance exploration and geophysical surveys.
  • Millrock Resources Inc. reported that its first phase of exploration at La Navidad project, targeting orogenic style mineralization, is now complete. A 1,082 samples soil survey has returned 248 samples with values greater than 50 ppb Au, while 83 rock chip samples of a total of 575 returned greater than 0.5 g/t Au. A ground magnetic survey covering 82 line-km and a 20 km induced polarization survey were also carried out in the property. Three prospects have been identified, Anchor, Horseshoe and Cobre, with rock sampling returning 24 m @ 0.9 g/t Au; 12 m @ 1.1 g/t Au; 14 m @ 0.8 g/t Au. A 2,000 m drill program on nine holes is in progress.
  • Prospero Silver Corp. provided a preliminary update on the first stage reconnaissance drilling at its Petate property in Hidalgo. Eight shallow holes have been completed with the aim to establish structure and better aiming at deeper targets. The initial holes were drilled at the Apartadero zone, which shows multiple jasperoid outcrops in limestone. Mineralized intercepts include 18.5 m @ 0.8 g/t Au, 5 g/t Ag; 3.4 m @ 3.5 g/t Au, 2 g/t Ag.
  • Sonoro Metals Corp. provided an initial description of its newly optioned Calera project in Sonora (see below on the deals section). “Large zones of disseminated pyrite replacement in the shallow dipping calcareous shale units are extensive with coincident regolith gold placer within the concessions. Local altered felsic dikes cut the mineralized meta-sedimentary rock units and may be associated with mineralization”.  Initial work is to surface sample the concession area, where multiple old prospect pits are located, and a soil sample program on east-west lines to identify targets for further exploration.
