ON MEXICO ISSUES

  • Andrés Robles Osollo, Vicepresident of government relations of the AIMMGM (Asociación de Ingenieros de Minas, Metalurgistas y Geólogos de México) pointed that México is a mining country, but that the industry has neglected the promotion of the craft and the importance of México on the World production of minerals. México is the leader in silver production, and is within the first ten producers of gold, copper, lead and zinc.
  • Arcelor Mittal announced the investment of 3,000 million pesos at Las Truchas mine in Michoacan, to increase the production rate from 1 M tonnes/year to 2.3 M tonnes/year. The company complained on the illegal blockage of the railroad line for three months in 2021 by a teachers Union, and said that they are working closely with the Michoacan government to keep the rails free of blockades.  

ON EXPLORATION

  • Radius Gold Inc. provided an update on the company’s exploration activities at the 10,250 ha Amalia project, in Chihuahua. The JV with Pan American Silver Corp. has completed 23,059 m of drilling in 67 holes on the California, Amalia and El Cuervo vein systems. Recent mapping and sampling extended the target for 1.5 km at California, and several parallel structures were identified. Pan American “has completed its right to earn an initial 65% interest in the Amalia Project by making cash payments to Radius totalling US$1.5 million (paid) and expending US$2 million on exploration over four years (completed). Pan American may earn an additional 10% by advancing the property to preliminary feasibility”.
  • Radius Gold Inc. informed on work at the Plata Verde project in Chihuahua. Fresnillo PLC has an agreement since mid-2022 to negotiate an option agreement to earn 70% interest in the project. Since then, Fresnillo has funded US$100 K on the signature of the agreement, paid US$65 in underlying property option payments, paid US$103 K in back taxes and invested US$35 K in the project. Fresnillo has to spend over a four-year period US$5 M in exploration and make option payments to Radius of US$3.1 M which includes US$1.1 M to cover underlying property payments. “Should either Party’s interest fall below 10% interest in NewCo that interest would convert to a 2% NSR”.
  • Radius Gold Inc. notified on exploration at its Maricela project in Sonora. The project is 20 km south from the Cananea copper mine, and only a few kilometers from the Loma de Plata silver deposit discovered a few years ago by Azure Minerals. Radius has “mapped and sampled an epithermal silver and gold mineralized vein system extending approximately 1.5km long by 300m wide, within which occurs multiple veins, stockworks and breccias. Vein intersections have exposed widths of up to 25 metres”. Highlighted chip sampling results comprise 3 m @ 4.46 gpt Au, 1,335 gpt Ag; 6 m @ 1.03 gpt Au, 418 gpt Ag; 25.3 m @ 0.31 gpt Au, 62 gpt Ag.

Mexico’s Best Drilling Intercepts, Third Week of September 2022

A busy week regarding press releases with drilling results from properties in Mexico. Eight companies posted drilling intervals, seven of which produced interesting gold numbers, five on relevant silver intercepts and a few with good base metals numbers. While the majority of intervals represent intercepts on intermediate to low sulfidation epithermal systems, the two projects with stronger gold intercepts represent a skarn system (El Limón Guajes in Guerrero) and a deposit likely to be associated, although distal, to an intrusive body (Camino Rojo in Zacatecas). Another skarn mineralization system, Adelita in Sonora, also returned high gold numbers. Low to intermediate sulfidation mineralization systems include all the highlighted silver intercepts of the week, of which the most relevant is the 10.20 m @ 1,404 gpt Ag announced by Vizsla at its Panuco project in Sinaloa. Both highlighted copper intercepts come from Skarn systems, while all relevant lead and zinc intercepts come from low to intermediate sulfidation epithermal systems.

ON MEXICO ISSUE

  • Equinox Gold Corp., informed that mining activities at its Los Filos mine in Guerrero have been temporarily suspended due to an illegal blockade by members of the nearby Mezcala community. The blockade is preventing delivery of certain supplies to the Los Filos Mine that are required to maintain operations. 
  • Rocío Nahle, Secretary of Energy announced that Lithium for Mexico (LitioMx) will hold the first meeting of its Board of Directors on September 20, 2002. The secretary added that the use of lithium is essential for the energy transition, since it allows the production of batteries. “Right now, it is in high demand around the world for its power to store electricity,” she stressed. She recalled that wind and solar plants are intermittent sources of energy, so “white gold” represents a great opportunity for the Mexican energy sector.
  • The Attorney General’s Office (FGR) reported that three arrest warrants have been issued against the same number of people, for the events that occurred in the Coahuila mine ‘El Pinabete’, where 10 workers are trapped. Since last August 5, the FGR began the investigation procedure for the events that occurred in the mine, owned by the mining company ‘El Pinabete’ S.A de C.V. The FGR reported that the arrest warrants are for the probable commission of the crime provided for and sanctioned in article 150 in relation to article 149 of the General Law of National Assets.
  • Mexican President, Andrés Manuel López Obrador does not rule out comprehensive mining law reform. A month after the collapse of a coal mine in Sabinas, Coahuila, where 10 miners remain trapped and rescue works do not seem to yield results, President López Obrador said he does not rule out a comprehensive reform to the Mining Law, aimed at preventing such incidents from happening again. The reform would also set stricter rules for extractive activities. López Obrador did not mention exactly when is he planning to propose his reform, but it seem to have the support from at least most of MORENAs senators and one of the most important Unions in Mexico.

ON EXPLORATION

  • Silver Spruce Resources Inc. along with Colibri Resource Corp. completed its phase 1 drilling program at the 1,057 ha Diamante project in Sonora. The 2,005 m reverse-circulation program in 19 holes, up to 135 m in depth, covered the La Prieta, and Pillado targets. “Mineralization is reported visually as pyrite, arsenopyrite, chalcopyrite, sphalerite, argentiferous galena, argentite, hematite and probable metal oxides, carbonates and sulphates, including copper carbonate (malachite), copper sulphates and plumbojarosite”.
  • Vortex Metals Inc. provided an update in exploration of its Riqueza Marina and Zaachila projects in Oaxaca. The late David Jones identified this area in the early 2000’s …”Copper-gold mineralization within both the Riqueza Marina and Zaachila projects is associated with geologic processes operative in the Late Jurassic to Middle Cretaceous within a back-arc sequence of bi-modal volcanics and volcaniclastics deposited on the sea floor. Early exploration conducted by Dave Jones identified several copper and gold anomalies over a broad area but clearly associated with specific rocks, i.e. exhalite, rhyolite debris aprons or breccia. These associations prompted the identification of a geologic environment which incorporated these features. The Volcanogenic Massive Sulfide (VMS) model incorporates the geologic and geochemical features observed to date”.
  • Kootenay Silver Inc. informed significant progress has been made on the 15,000 m drilling campaign at Columba, in Chihuahua.
