  • Compañía Minera Cuzcatlán (Fortuna Mines), called for the civil organizations promoting an illegal blockage of the San José mine in Oaxaca to reconsider its program. The blockage is being called to pressure the authorities on the delivery of resources, an issue completely unrelated to the mining company.
  • In 2019 Mexico fell nine positions, according to the Fraser’s Institute. Mexico’s shine to attract mining investment is getting dull with the lack of confidence and certitude derived of the president’s declarations on the review of mining concessions and the recent disappearance of the Mining Sub Secretary. The federal government has been clear, under his tenure no mining concessions are to be issued. The president has stated that up to 40% of the country ground has been under mining concessions, and that amount should suffice (for mining companies) for thousands of years.
  • Armando Ortega, president of the Mining Task Force of the Cámara de Comercio de Canadá en México (Cancham) stated that the mining environment in Mexico is not propitious because political signals of ideological nature are not favorable to investment, and some measures announced by the government are worrisome. Among the factors supporting its points are: initiatives to forbid open pit mining; initiatives to enlarge natural protected areas, encroaching to areas of active mining; the initiative to change the law on water use, changing its regime from concession to license; the stated fact by the president to not to grant a single mining concession during his tenure; the disappearance of the Mining Sub Secretary; the extortion by unions to companies, exemplified by the tricky wining by Napoleón Gómez Urrutia of the collective contract at is Cosalá mine complex in Sinaloa.  
  • According to a Camimex post, projects that are coming into production include an expansion at Los Filos, Guerrero (Equinox Gold); Ixtaca, Puebla (Almaden Minerals); Camino Rojo, Zacatecas (Orla Mining); Las Chispas, Sonora (SilverCrest Metals); Santana in Sonora, La Fortuna in Durango and Cerro de Oro in Zacatecas (Minera Alamos).  
  • Guanajuato announced its intention to conform a Mining Cluster.
  • Fernando Alanís, Camimex (Cámara Minera de México) president, explained some facts on how mining concessions function in Mexico. According to the constitution everything under the surface is property of the Nation, hence the permit needed to extract gas, oil, water or minerals by individuals or companies, permit that is precisely a concession. In mining the concession is a permit to explore and mine an ore deposit if found, it provides no rights for surface rights, reason for which an agreement has to be negotiated with the surface owner to access the land. He stressed that having a mining concession is no guarantee of finding an ore deposit. To keep a mining concession, the concessionaire has to pay every six months a due per hectare, due that increases with the age of the concession, to avoid speculative land grabs; and also the concessionaire has to comply with a minimum yearly investment that also increases with the age of the concession, again to avoid speculation. According to the DGM (Dirección General de Minas) 20.7 M hectares are concessioned in México, out of almost 200 M hectares in the country, meaning about 10.35% of the country is concessioned, of which only 1 M hectares include a project in exploitation. The government granting of mining concessions is the more efficient way to exploit the natural resources, letting others run the risks and expensive investments of exploration. The government receives the due payments, and in case of an ore body being found and a mine built, receive taxes for its operation. Mining is the economic activity that has the steepest rate of taxes and dues, which add up to 55% on the income of mining firms.


  • Brigadier Gold Ltd. released sampling results from two vein systems at its Picachos property in Sinaloa. Highlighted results comprise 7 m @ 160 gpt Ag, 0.6 gpt Au; 3 m @ 205 gpt Ag, 0.2 gpt Au; 0.5 m @ 356 gpt Ag, 6.6 gpt Au at the Garabato vein system, and 1.6 m @ 1.9 gpt Au, 98 gpt Ag, 0.6% Cu, 3.7% Pb, 1.5% Zn; 1.0 m @ 21.3 gpt Au, 5 gpt Ag, 3.2% Pb, 0.8% Zn; 0.2 m @ 56.7 gpt Au, 288 gpt Ag, 1.9% Cu, 5.9% Pb, 1.3% Zn at El Pino.

At Los Campos, dump sampling returned up to 0.3 gpt Au, 254 gpt Ag, 0.12% Pb, 0.07% Zn. The Nueva Andromeda claim, adjacent to San Celso, has been optioned.

  • Advance Gold Corp. reported on the drilling done at its Tabasqueña project in Zacatecas. “Of the four holes drilled to date into the 3500-metre continuous IP chargeability anomaly, drill hole AGT-16 has encountered the best mineralization, including a 10.7 metre sulphide zone. Mineralization in this hole has zones of semi-massive pyrite, containing 15 to 30% pyrite, together with up to 3% sphalerite and some galena (core photos shown below and on company website). The first three holes intersected stacked lenses of disseminated sulphides and are around 3000 metres to the south of AGT-16”.


  • Mexus Gold US. is nearing the completion and test running of its high grade ball mill gravity gold recovery system at its Santa Elena mine in Sonora (not to mistake with First Majestic’s Santa Elena mine, also in Sonora). The company will mill material from a quartz vein with a 10 gpt Au cutoff, and recover the gold through the gravity system, while lower grade ore continues to be placed on the heap leach.
  • Starcore International Mines Ltd. Reported results of the first quarter ended July 31, 2020. Production during the period at its San Martin mine in Queretaro included the milling of 59.1 K tonnes @ 1.70 gpt Au, 29.2 gpt Ag, recovering 88.8% Au, 56.5% Ag, to produce 2.9 K Oz Au, 32.5 K Oz Ag.

Underground exploration is focused on expanding and further defining known mineralization. Surface exploration is focused on near mine targets around the Platosa deposit and the Jaboncillo and PDN targets north of the mine. Jaboncillo, 11 kilometres northwest of the Platosa Mine, is a Platosa-style target with a 4 x 4 kilometre alteration footprint, multiple times the size of the Platosa footprint, where the Company intersected near-surface gossans in 2019 drilling. PDN, two kilometres north of the Platosa Mine, is a skarn-style geophysical target that may be associated with the skarn discovery made in 2012 at Rincón del Caído”.
  • SSR Mining Inc. informed it is planning to spend $5 M in 2020 at Pitarrilla, Durango. The investment is part of a “program to extend an existing decline to provide drill access to the underground Mineral Resources. An improved geological model from work completed in 2019 indicates strong potential to better define known, high-grade mineralized veining associated with steeply dipping rhyolite dyke contacts. Extending the underground ramp provides access for tighter spaced drilling at better orientations to test the rhyolite dykes and veins for continuity. If infill drilling confirms the continuity of high-grade mineralized structures, there would be potential to enhance the grades of existing Mineral Resources“.


  • Sonoro Metals Corp. changes name to Sonoro Gold Corp. on September 9, 2020 (Cerro Caliche, Sonora).   
  • Barksdale Resources Corp. informed thatFollowing a detailed due diligence campaign, the Company identified certain title issues with respect to three of the twelve mining concessions comprising approximately 307.46 hectares of the total lands covered under the option. Tusk Exploration Ltd (“Tusk”) is in the process of rectifying these title issues and expects the process to be completed in 2021. Until the title issues have been rectified, Barksdale and Tusk have agreed to defer 35% of the Year 1 and Year 2 option cash and share payments” (San Javier, Sonora).
  • Southern Silver Exploration Corp. closed the transaction with Electrum Global Holdings L.P. to acquire Electrum’s 60% indirect working interest in the Cerro Las Minitas project in Durango.
