Highlights on the Second Week of November 2016, Mineral Exploration in Mexico

During the second week of November, at least 27 press releases were published by companies working in Mexico, including several quarterly financial reports. ON EXPLORATION, a new round of drilling started in two Durango projects, while another company published high-grade drilling results and the exploration for extensions to defined orebodies, also in Durango.  In Sonora one company is exploring a new porphyry copper target and also a new high sulfidation epithermal target. Assay results were disclosed for a drill hole in Veracruz, with continuous low-grade Cu-Au mineralization for hundreds of meters. In Sonora, step-out drilling exploration is finding extensions and peripheral mineralization in two high sulfidation epithermal projects. Also in Sonora, the resource conversion in a lithium property has been completed, and work focus in the Feasibility Study. A drill program is to start on another lithium property in Sonora. ON MINING, ten companies reported third quarter results, with operations in Baja California, Sonora, Sinaloa, Coahuila, Durango, Jalisco, San Luis Potosi, Mexico State, Oaxaca and Zacatecas. Pilot scale mining continues on a Sinaloa project, and a mine commenced commercial production in Zacatecas. ON FINANCING, one company issued shares for $150 K to settle debt; another closed a non-brokered private placement for $400 K; and one other received $642 K from the exercise of warrants. One company entered into an agreement with a syndicate of underwriters for $20 M. ON DEALS AND CORPORATE ISSUES, two companies entered into an option agreement for 50% of a property in Durango, while two other companies agreed an option and JV agreement for 49% of a lithium property in Sonora.

ON EXPLORATION

  • Orex Minerals Inc. has started a new round of diamond drilling on the Sandra Escobar project in Durango; two rigs will drill 4,000 m in 10 to 15 holes. Results from the last holes of the past campaign were released, and include 10.89 m true width (TW) @ 55 g/t Ag, on the Puma ridge zone, 250 m southwest from the Main Zone.
  • HECLA Mining Corp. updated exploration work at its San Sebastian mine in Durango, where focus was in defining extensions to the current Middle and North veins pits. Drilling of the West Middle vein, 350 m form the Middle vein pit has defined a high grade zone of mineralization more than 375 m in length, between 100 and 240 m below the surface. Intercepts include 2.6 m @ 7.4 g/t Au, 1,558 g/t Ag and 0.8 m @ 18.6 g/t Au, 4,643 g/t Ag. Drilling continues at extensions of the East Francine vein over 240 m of length at 1.2 – 4.5 m widths and the West Francine vein over 480 m of length and 0.6 – 4.8 m widths.
  • Orex Minerals Inc. announced that its project partner Fresnillo PLC has commenced a 5,000 m Phase-V diamond drill program in 11 holes at its Coneto property in Durango. The new drilling will cover La Bufa, Santo Niño, Reliz, Loma Verde, Descubridora, Durazno, Impulsora and Promontorio veins.
  • Minaurum Gold Inc. identified a new bulk-tonnage target at La Quintera silver property in Sonora. “The Minas Nuevas bulk-tonnage target has a strike length of 700 meters and is 25 meters wide…….. Mineralized stockwork quartz veining surrounding the old workings exhibits the potential for bulk-tonnage silver mineralization”.
  • San Marco Resources Inc. has found typical porphyry copper zoned alteration of a quartz diorite porphyry with copper and molybdenite mineralization in Sonora. Another target hosts a high sulfidation epithermal system in volcanic and volcanoclastic rocks with advanced argillic alteration. Dacite breccias and pyroclastics show quartz/alunite alteration and vuggy silica areas.
  • Almadex Minerals Ltd. disclosed results from its last hole on the Norte Zone at its El Cobre project in Veracruz, with 414 m @ 0.11% Cu and 0.16 g/t Au, including 74.5 m @ 0.19% Cu and 0.38 g/t Au. The company will now test a new zone interpreted as the intrusive core of the porphyry system, supported by a chargeability anomaly. The four copper-gold porphyry targets currently known are: Encinal, El Porvenir, Norte and Villa Rica. The largest target area is the Villa Rica zone which has not been drill tested.
  • Alamos Gold Inc. released results from its exploration in Sonora. At La Yaqui 9,055 m of drilling have been completed since the October interim resource update and additional 5,000 to 6,000 m is planned for the current quarter. New infill drilling intercepts include 76 m @ 4.37 g/t Au, 76.8 m @ 3.17 g/t Au and 61.8 m @ 1.1 g/t Au. At Cerro Pelon exploration now includes a much larger area to be systematically explored. Twenty holes were completed for 5,692 m of drilling, with structures, vuggy silica and advanced argillic alteration intersected over a broad area.
  • Bacanora Minerals Ltd. is realizing multiple activities with the aim to complete the definitive Feasibility Study (“FS”) on its Sonora lithium project. The infill drilling program to upgrade the resource classification has been completed. The average thickness for the Upper Clay Unit is 30.7 m @ 1,791 ppm Li, and for the Lower Clay Unit 20.7 m @ 4,345 ppm Li.
