  • No Relevant News.


  • Zenith Minerals Ltd. commenced a near surface, 11 auger holes, drill program on a salt pan 4 km long by 2 km in width in San Juan del Salado, San Luis Potosi . The drilling is to test for near surface lithium brines to a maximum depth of 25 meters. Both sediments and brines are to be sampled.
  • Almadex Minerals Ltd. received assays for the top 300 m of its first hole in the El Encianl zone of the El Cobre project in Veracruz. A 296.7 m intercept @ 0.32 g/t Au, 0.13% Cu includes 51.73 m @ 0.42 g/t Au, 0.17% Cu; and 100.47 m @ 0.44 g/t Au, 0.15% Cu. Almadex interpretation is that this hole intercepted significant mineralization that is proximal to a porphyry core.
  • Galore Resources Inc. announced that a troublesome drilling program at its San Jose claim in Zacatecas was terminated (see below) after it was forced to abandon its first hole. The company has decided to focus the exploration on the adjoining El Alamo claim, which differs significantly in mineralization style.
  • Santana Minerals Ltd. reported assay results for the first RC (reverse circulation) drill holes testing the southern extension of the Mojardina prospect at its Cuitaboca project in Sinaloa. Shallow drill intercepts include 53 m @ 47 g/t Ag; 15 m @ 100 g/t Ag; 7 m @ 53 g/t Ag, all of these less than 3 m from the surface.


  • Mexus Gold US. continues in the start-up period of cyanide leaching at its Santa Elena mine in Sonora, near Caborca (not to mistake with First Majestic’s Santa Elena mine, also in Sonora).
  • Arian Silver Corp. presented its financial results for 2016. During this period the company divested of the Calicanto silver project in Zacatecas, and focused in lithium properties in the Altiplano.

Twelve concessions were still held on four projects: San Celso, Los Campos, La Africana and Calicanto, and three other properties near San Celso.
  • Santacruz Silver Mining Ltd. intersected the high-grade zone of the Membrillo vein at the Membrillo prospect in San Luis Potosi. Eight muck samples from the production drift assayed 0.10-0.59 g/t Au, 8-121 g/t Ag, 0.12-0.40% Pb, 0.62-7.07% Zn over 0.40 – 0.90 m of true thickness of the vein. “Management anticipates delivering 250 tpd of material from the Membrillo Prospect to the Rosario mill for processing during the third quarter of 2017.”


  • Monarca Minerals Inc. settled an aggregate of $463 K in debt with certain of its creditors. Concept Capital Management Inc. now owns 6.5% and 13.9% of the issued and outstanding common shares (Tejamen, Durango).

Drill hole intercepts include 5.25 m @ 1.2 g/t Au, 40 g/t Ag, 0.6% Cu, 1.4% Pb, 7.4% Zn; 5.08 m @ 3.2 g/t Au, 261 g/t Ag, 1.3% Cu, 4.3% Pb, 11.8% Zn; 6.64 m @ 1.49 g/t Au, 220 g/t Ag, 0.7% Cu, nil Pb, 13.2% Zn.
  • Oceanus Resource Corp. released final assays for hole ET-17-144 on the Protectora vein of El Tigre property in Sonora. In a previous release the 0.85 m drill intercept (0.80 m true width, or TW) returned 37.2 g/t Au, 7,339 g/t Ag, and the new release adds assays of 2.84% Cu, 1.38% Pb, 4.06% Zn to the same interval. The nearby Palomitas tunnels have historical reports of 1.1 m @ 3.77 g/t Au, 1,714 g/t Ag (50 Oz/ton).
