ON MEXICO ISSUES

No relevant news.

ON EXPLORATION

  • Aloro Mining Corp., commenced a 3.6km road construction and building of 12 permitted drill pads at its Los Venados project in Sonora. “The road construction will open up new exposures for sampling in mineralized areas and structure that were previously undercover”.
  • San Marco Resources, commenced a drilling program at its Chunibas project in Sonora where they have a JV agreement with Antofagasta plc. The drilling program will consists of initial 1,500m comprised in six holes with the goal of testing down dip and along strike high-grade Cu-Ag mineralized mantos hosted in volcanic rocks in different stratigraphic levels. The manto-type mineralization has been identified along a corridor of 1.7km long and at least 300m wide.
  • Sonoro Metals Corp., reported results from the initial 13 drill holes from its Cerro Caliche project in Sonora. Significant intersections are: Hole SCR-002 with 27.43m of 0.6 g/t Au and 7 g/t Ag; Hole SCR-003 with 30.48m of 0.5 g/t Au and 8 g/t Ag; Hole SCR-004 with 39.62m of 0.9 g/t Au and 9 g/t Ag, including 6.09m of 2.9 g/t Au and 20 g/t Ag; Hole SCR-005 with 10.67m of 0.7 g/t Au and 21 g/t Ag, and 10.67m of 0.6 g/t Au and 1 g/t Ag; Hole SCR-006 with 10.67m of 1.2 g/t Au and 21 g/t Ag, including 6.1m of 2 g/t Au and 26 g/t Ag; Hole SCR-007 with 22.86m of 0.9 g/t Au and 13 g/t Ag, including 4.57m of 2.2 g/t Au and 20 g/t Ag; and SCR-008 with 36.58m of 0.5 g/t Au and 4 g/t Ag. “The drilling has further confirmed that mineralization in the Los Japoneses zone remains open in all directions, including at depth.”
  • Minaurum Gold Inc., discovered two new vein zones at its Alamos Silver project in Sonora: the San Jose vein, a NNE trend structure hosted in a fault zone which can be traced for at least 3km long, and the Santa Rosa vein, a stringer-quartz veinlets structural zone that runs for at least 300m along strike. The discovery of the new veins was through its ongoing district-scale reconnaissance program. Sampling on the San Jose vein returned grades ranging from anomalous up to 1,995 g/t Ag, 2.5% Cu, and 1.9% Zn, while sampling on the Santa Rosa vein only retuned anomalous values.
  • Discovery Metals Corp., completed a 40 line-km ground magnetic survey at its Monclova project in Coahuila to cover three targets: Real Viejo with 23 lines spaced 50m apart, Corrales with 17 lines spaced 100m apart, and Soledad with 12 lines spaced 50m apart. “Results of the Real Viejo survey highlight a linear magnetic high parallel to the mapped mineralized and altered zone along the southern boundary of the Monclova intrusive complex centered on the Project. This suggests continuity of the alteration and/or mineralization along the contact and provides support for the holes planned to test this zone. Interestingly, similar magnetic high zones occur across the neighboring Corrales target. Both linear magnetic highs as well as linear lows are highlighted by the survey and represent prospective targets on the Project. Results at the northern Soledad grid also highlight similar geometries”.

  • Kootenay Silver Inc., designed a program of 15,000m of drilling over 62 holes aimed to expand resources along the extensions of its La Cigarra deposit in Chihuahua. The drilling program will be conducted on four target areas where the company believes there is untested potential to increase resources. “The plan would entail primarily exploration step out drilling of known mineralization and some infill drilling of the successful La Borracha program earlier this year”. “The four areas Kootenay plans to target are the La Borracha high grade (the mineralized trend located 1,000 meters northwest from the northern boundary of the Resource), the La Borracha Connection (connecting La Borracha with the San Gregorio area of the Resource), Gap (a very under drilled area between the main San Gregorio and Las Carolinas zones that currently comprise the Resource) and the Carolinas Extension (the strike extension of the Resource to the southeast)”.
  • Hecla Mining Company, released in-fill drilling results for its San Sebastian mine in Durango. The in-fill drilling was conducted in the central portion of the polymetallic zone along the Francine Vein. Additionally, exploration core drilling was also conducted toward shallower oxide mineralization along the West and East Francine vein areas, the recently discovered South Vein, and at the Esperanza Vein target area. At the Francine vein, the in-fill drilling program intersected high grade mineralization. Highlights include 1.37m of 591 g/t Ag, 4.8% Cu, 16% Pb and 13.5% Zn and 2.25m of 227 g/t Ag, 1.8% Cu, 3.5% Pb, and 6% Zn. The drilling also intercepted narrow but high-grade mineralization along the East Francine vein on new zones of vein-hosted oxide mineralization. Significant intersections are 1.46m of 485 g/t Ag and 0.3 g/t Au, and 2.83m of 299 g/t Ag and 2.2 g/t Au. Mineralization in this area is defined over 1,200 feet along strike and 800 feet down-dip and this new zone could represent an important new source of oxide mineralization. At the West Francine vein, the drilling program encountered also narrow intervals of high grade. Highlights include 0.64m of 1,791 g/t Ag and 0.62 g/t Au. Mineralization in this area is open laterally and at depth. Follow-up, offset drilling is in progress. At the Esperanza vein, exploration drilling commenced but results are pending. Reconnaissance RC drilling discovered a new blind vein under soil cover in the Saladillo Valley. This new vein, referred as the South vein, intercepted significant mineralized intervals such as 2.83m of 392 g/t Ag and 2.5 g/t Au, 2.86m of 187 g/t Ag and 0.93 g/t Au, and 2.86m of 174 g/t Ag and 1.24 g/t Au. Drilling for the remainder of the year will continue to focus on expanding resources and evaluate near-surface oxide mineralization at the West Francine Vein, South Vein, and Esperanza Vein areas.

ON DEALS AND CORPORATE ISSUES

  • Sable Resources Ltd. announced its intention to conduct a two-phase drill program on the 1.7 km long structure at its Margarita project in Chihuahua. Twenty nine out of forty four surface samples collected returned over 100 g/t Ag, peaking at 909 g/t Ag, with high anomalies in gold, lead, zinc, arsenic and antimony. The 125 has property is surrounded by Sunshine’s Los Gatos project, same that hosts a 178 M AgEq Oz resource (which is under development). The initial drill program will consist of a two-phase, 11 diamond drill hole program totaling 4,025 m to test the vein structures at depths between 200 and 400 m. Considering the silica textures on the veins, the company believes they are at the upper levels of an epithermal system.
  • Aztec Minerals Corp. announced it expects to receive the assays for the first five holes drilled at the Cervantes Au-Cu porphyry property in Sonora. These five holes were drilled in December, and part of the 3,000 m, 14 to 17 holes, phase 1 drill program that is currently underway.
