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

During the first week of November, at least 32 press releases were published by companies working in Mexico, including a fair amount of quarterly financial reports. ON MEXICO NUMBERS AND NEWS, a letter was delivered to the Mexican president by CANCHEM, suggesting points to be addressed by the government to make the country more competitive for attracting foreign investment. Canadian corporations and the Canadian ambassador ask for surface access conditions akin to those of the energy sector in Mexico. ON EXPLORATION, a technical report was filed from a property in Sonora. A project in Chihuahua is seeing drilling at several targets, while other in the same state reported mapping, prospecting and geophysical surveys. A property was drilled in Zacatecas, showing somewhat narrow but high grade gold intercepts. In Sonora, an agreement has been reached to allow access for drilling, while in a Durango property the drilling continues. A project in Puebla is to see a PFS by early 2017. ON MINING, nine companies reported third quarter production results for its operations in Sonora, Sinaloa, Chihuahua, Durango, Guanajuato, Guerrero and Oaxaca. A fatality was reported on a mine in Guerrero, and a pit in Sinaloa reached the high grade part of the orebody. In Durango, the construction of a new mine has been announced. ON FINANCING, one company filed documents for a private placement for $460 K, and one other sold shares in another junior company for $650 K. ON RESOURCES, a maiden silver resource was announced for a property in the foothills of the Sierra Madre in Durango. ON DEALS AND CORPORATE ISSUES, the closing of the acquisition of three properties in Chihuahua was announced, the lease of a mill was extended in Durango, and the farm-out agreement of another property in Guanajuato was completed.


  • Cámara de Comercio de Canadá en México (CANCHAM). In a letter to the president of Mexico, Enrique Peña Nieto, this organization established five points on which the effort to attract foreign investment on the Mexican mining industry is failing. 1) The weakness on the rule of law. The recent illegal blockade at the Peñasquito mine in Zacatecas is an example. 2) Judicial uncertainty. Surface access delays and conflicts are common, and radical rules change a hindrance. 3) Increasingly unfavorable fiscal rules that maim competition on a global market. 4) An aggressive SAT (Mexican IRS) tax collection policy, increasing audits and lengthy delays to recover VAT. 5) Security, evidence of which is found on the gold and silver robberies at mining sites. CANCHAM MÉXICO calls for effective action pairing the internal efforts with the international promotional messages to attract investment, so Mexico can recover the lost positions against other investment recipients in the hemisphere, and expecting an effective coordination among the different government levels in mining.
  • Canada has participated with 45.2% of the direct foreign investment in Mexico in the period 1999-2015, and 42% of that amount was on the mining industry, mostly on the extraction of precious metals. According to Canadian corporations, the Mexican government offered to equalize the scheme to facilitate the access to the surface from the Energy sector (approved on the energy reform two years ago) to the mining sector. As stated by the Canadian ambassador, the Canadian corporations are eager to establish forums with all the involved to promote a better understanding and improve communications.


  • Almaden Minerals Ltd. expects to complete ongoing studies in 2016, and complete a Pre-Feasibility Study early in 2017, for its Ixtaca property in Puebla. Continued metallurgical work backs the amended Preliminary Economic Assessment (PEA) recovery projections of 90% for gold and silver for the limestone domain, which in turn represents about 90% of the metal to be produced under the amended PEA. Gravity concentration and flotation are to be used to obtain those recovery levels.
  • Kootenay Silver Inc. reported that 11 core drill holes totaling 2,100 m have been completed and submitted for assaying on the Ram Zone as part of its initial 3,000 m drill program on its La Cigarra project in Chihuahua. The drill rig is to test now the La Soledad zone, 1 km south from the La Cigarra defined resource. An extended multi-phase drill program is expected to be executed on the next 12-18 months, focusing on several new prospective targets on the property.
  • Candelaria Mining Corp. announced the results of the completed diamond drill program at its Pinos project in Zacatecas. The program initiated last May and was carried out on the Cinco Estrellas vein, over a strike length of 2.2 km. Significant intercepts include 1.95 m @ 5.88 g/t Au, 28 g/t Ag (including 0.8 m @ 14.2 g/t Au, 40 g/t Ag); 0.9 m @ 4.84 g/t Au; 6.4 m @ 1.65 g/t Au, 18 g/t Ag (including 0.75 m @ 5 g/t Au, 17 g/t Ag); 1.8 m @ 2.87 g/t Au, 71 g/t Ag (including 0.32 m @ 11.05 g/t Au, 275 g/t Ag); 6.9 m @ 2.52 g/t Au; 4.25 m @ 4.32 g/t Au.
  • SilverCrest Metals Inc. has filed a technical report on its Las Chispas property in Sonora, which is available on SEDAR (sedar.com).
  • San Marco Resources Inc. has reached surface right access with the local ejido at its Chunibas project in Sonora. San Marco is now to advance the permitting process for trenching and drilling. Past drilling on the property include 42.6 m @ 1.04 g/t Au, 22.9 m @ 2.04 g/t Au and 15.2 m @ 2.8 g/t Au. “Mineralized shear/veins are generally 1 – 2 metres in width, but are surrounded by haloes of lower grade stockworks, breccias and fractures that constitute broader targets. This disseminated style of mineralization occurs in intrusive host rock without visible vein or shear development”.
  • Consolidated Zinc Ltd. has identified several new mineralization occurrences while realizing regional geological, geochemical and geophysical exploration work around its Plomosas project in Chihuahua. Geological mapping and prospecting was followed by gravity and helicopter-borne magnetic surveys. Prospecting identified two main gossanous occurrences: El Fenomino area is 2.5 km NW from the Plomosas mine, where a manto outcrops over a 100 m,  and 5 – 7 m in thickness, with anomalous Pb (up to 4.4%) and Zn (up to 1%). At Los Alfonsitos mine several gossanous outcrops were noted while mapping, with samples away from the workings returning 8 – 39 g/t Ag, 0.4% – 1.9% Pb and 0.6% – 1.1% Zn. The magnetic survey identified similar magnetic signatures to the mine sequence, and confirmed structures detected by the gravity survey.
