At El Castillo, in Durango, 2.22 Mt (tonnes) of waste, and 2.15 Mt (tonnes) were moved, with 2.12 Mt ore @ 0.37 g/t Au crushed to the pads to produce 10,079 Oz Au, 8,111 Oz Ag at cash cost $992 per Au Oz. At San Agustin in Durango, 618 Kt of waste, 1.85 Mt of ore were moved, with 1.88 Mt of ore @ 0.36 g/t Au crushed to the pads to produce 15,528 Oz Au, 55,781 Oz Ag. At La Colorada, in Sonora, 1.81 Mt of waste, 1.06 Mt of ore were moved (32 K tpd), with 1.14 Mt of ore @ 0.36 g/t Au crushed to leach pads to produce 11,503 Oz Au, 29,360 Oz Ag at cash cost $833. “The Company expects the third quarter 2018 will see lower production due to the lower grades stacked on the leach pad during the second quarter 2018 and also expects higher costs during the third quarter 2018 associated with drilling, blasting and hauling costs for normal state operations”.” While the Company’s explosives permit has been reinstated at La Colorada, the legal action brought against the Secretary of National Defense and the Municipality of La Colorada continues through the Judiciary court process”.
  • Alio Gold Inc. reported second quarter 2018 results. The San Francisco mine in Sonora produced 14,466 Oz Au, 7,661 Oz Ag at by-product cash cost $950 per Oz Au, while AISC was $1,172 per Oz Au. The Company is reducing stripping and focuses mining on more profitable ounces to maintain cash neutral operations. As a result of the reduced stripping, the ”production guidance of 90,000 to 100,000 ounces of gold for 2018 will not be met.” At Ana Paula in Guerrero, all development work including the construction of the underground decline, the completion of the feasibility study and further exploration have been temporarily suspended as result of the recent decline in the gold price.
  • Odyssey Marine Exploration Inc. reported second quarter 2018 results. “Odyssey holds a controlling interest in Oceanica Resources, S. de R.L., and ExO, a subsidiary of Oceanica. ExO controls exclusive 50-year mining permits in an area in Mexican waters that contains a large amount of phosphate mineralized material”.” On March 21, 2018, the 11-judge panel of the Superior Court of the Federal Court of Administrative Justice in Mexico ruled unanimously in favor of ExO, nullifying the original denial of the environmental permit application.“ (Don Diego, Pacific Ocean cost of Baja California Sur)

ON MEXICO ISSUES

  • No relevant news

ON EXPLORATION

  • Minaurum Gold Inc. released results from its on-going drill program at its Alamos silver project in Sonora. The first hole ever drilled in the Europa-Guadalupe vein system intersected 8.25 m (core length) @ 1,760 g/t Ag (57 opt), 1.6% Cu, 1.5% Pb, 2.6% Zn. Other results comprise 16.75 m @ 0.13% Cu; 0.5 m @ 0.92% Cu, 0.1% Pb, 0.18% Zn; 1.2 m @ 541 g/t Ag, 0.28% Cu, 0.44% Pb, 0.88% Zn; 3.05 m @ 0.19% Cu; 0.35 m @ 185 g/t Ag, 1.05% Cu, 2.37% Pb, 1.44% Zn; 9.60 m @ 88 g/t Ag, 0.24% Cu, 0.37% Pb, 0.33% Zn (including 2.65 m @ 147 g/t Ag, 0.25% Cu, 0.21% Pb, 0.28% Zn).
  • 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.
  • Mammoth Resources Corp. released results from the first two holes drilled by the company at its Tenoriba project in Chihuahua. The El Moreno area is 1.4 km west from previously drilled holes, with two drill holes completed of three planned. Results comprise (core length intervals) 30.0 m @ 0.77 g/t Au (including 5.9 m @ 3.41 g/t Au); 80.0 m @ 0.17 g/t Au (including (9.0 m @ 0.51 g/t Au; 15.5 m @ 0.35 g/t Au). The presence of a feldspar porphyry moderately to weakly silicified and argillitized, which is locally strongly silicified and bearing a strong pyrite (up to 15%) and tourmaline (up to 10%) content in one hole is regarded as an indication of a good high sulfidation system, as well as the identification of dickite, kaolinite and illite in the other hole.
  • Prospero Silver Corp. has begun drilling at its Pachuca SE project in Hidalgo. The drilling is to be conducted under the terms of a strategic investment with Fortuna Silver Mines Ltd. A three to four drill hole, 1,800 m program is planned to test two targets in the 7,250 has land package. Epithermal style argillic alteration is associated with anomalous Au-Ag-Zn geochemistry into an andesitic and felsic volcanic pile. The first hole is to test an actively mined clay pit on a structurally controlled illite alteration zone.
  • Silvercrest Metals Inc. presented a summary of 2017 exploration results at its Las Chispas property in Sonora. During 2017 the company drilled 32,822 m in 125 holes, bringing the total to 41,418 m in 157 holes. To date nine of nineteen epithermal veins have been drilled. The most remarkable is the Babicanora vein, with an estimated width of 3.0 to 3.5 m, a high grade footprint of over 1.0 km and a precious metal zone of 125 to 175 m high, with the vein remaining open along strike and to depth. The best hole in this vein intersected 3.1 m @ 40.4 g/t Au, 5,375 g/t Ag. Other veins with high grade intercepts include the Babicanora Footwall, La Blanquita, Las Chispas, Granaditas, Amethyst and Tajo Chico. Initial metallurgical test have indicated recoveries of 98.9% Au and 86.6% Ag. Securing land access has included the purchase of a 2,500 has. ranch and 20 year lease contracts. For 2018 the company is planning to release a maiden resource estimate on the first quarter, with ore from the Babicanora, Babicanora FW, Giovanni, Las Chispas and William Tell veins, and from the old dumps. Further drilling will continue to focus on the 3.2 km long Babicanora vein, extending to the SE and to depth; other areas of drilling will include the Amethyst, Babi Sur, La Victoria and Las Chispas vein extensions. During the first half of 2018 Silvercrest plans to drill an additional 10,000 to 15,000 m, focusing on a planned updated resource and completed PEA in the second half of the year.

ON MINING
