ON EXPLORATION, in Sonora, Tocvan Ventures informed the RC drilling program has been completed at its Pilar project. In Chihuahua, Radius Gold informed on the status of its Amalia and Plata Verde projects; Mammoth Resources informed it has signed a surface agreement with two ejidos at Tenoriba. In Sinaloa, Mithril Resources released drilling results from Los Reyes, Copalquin.

  • The Covid pandemic has not dented mining company’s performance on the BMV (Bolsa Mexicana de Valores). At the beginning of the year the four biggest companies in the BMV (Grupo Mexico, Peñoles, Frisco and Autlán) were worth $524,500 million pesos, and now these are valued in $796,500 million pesos (US$39.5 billion), a 51.8% increase. These gains contrast with the expected decline of 25% in exploration, partly die to the pandemic, partly also due to the lack of certitude on government policies, delays or denials of permitting (see note on Almaden) and a greater tax burden.


  • Radius Gold Inc. informed on the exploration status of its projects in Mexico. At Amalia, in Chihuahua, Radius’s joint venture partner, Pan American Silver Corp. is funding and operating the phase 4 drill campaign, of which 1,838 m in 4 holes have been completed. At Plata Verde, also in Chihuahua, orientation induced polarization and ground magnetic surveys are being conducted. The target mineralized breccias occur under less than 100 m of volcanic cover rocks, and the geophysical surveys are planned to aid drill targeting.
  • Mammoth Resources Corp. announced the second of two ejidos (community held surface land) voted in favor of a two-year surface agreement for exploration at its Tenoriba project in Chihuahua. During “the term of the agreements the Company will be making contributions towards a number of community benefit programs and looks forward to reporting on these contributions. Mammoth will also be providing assistance to a number of the most vulnerable inhabitants of both ejidos”.
  • Mithril Resources Ltd. released good drilling results from Los Reyes target at Los Reyes project in Durango (not to mistake for Prime Mining’s Los Reyes project in Sinaloa).  Highlighted core length intercepts comprise 2.22 m @ 32.35 gpt  Au, 185 gpt Ag; 0.70 m @ 9.3 gpt Au, 125 gpt Ag; 1.20 m @ 2.05 gpt Au, 85 gpt Ag in one hole and 3.0 m @ 2.86 gpt Au, 84 gpt Ag (including 0.6 m @ 9.79 gpt Au, 165 gpt Ag) in other. Drilling is to recommence in early January 2021 at El Refugio target, whereas soil sampling is programmed for El Refugio West, La Soledad West, El Indio and Zaragoza prospects in January-February 2021.
  • Prismo Metals Inc. completed its 2020 drilling campaign at Palos Verdes, Sinaloa. A total of 436.8 m were drilled in four holes, and a fifth hole is to be completed in January 2021.

  • Equinox Gold Corp. reported that “the blockade by members of the Carrizalillo community at the Company’s Los Filos Mine in Mexico has been removed and access to the mine has been restored.

Measured and indicated resources now consist of 5.36 M tonnes @ 182 gpt Ag, 0.12 gpt Au, 0.49% Pb, 0.58% Zn (215 gpt AgEq), and inferred resources of 4.89 M tonnes @ 146 gpt Ag, 0.18 gpt Au, 0.43% Pb, 0.69% Zn (183 gpt AgEq). (Note.- this should amount to close to 55 M Oz Ag, not counting other metals credits).

  • VanGold Mining Inc. signed a binding letter agreement with Endeavour Silver Corp. to acquire the El Cubo mill and mill complex, in Guanajuato, 8 km from its El Pinguico property.

El Cubo has measured, indicated and inferred resources of 2.4 M Oz Ag and 28.2 K Oz Au.
  • Almaden Minerals Ltd. Has received notification from the Mexican federal permitting authority, Secretaría de Medio Ambiente y Recursos Naturales (SEMARNAT) that the company’s initial environmental permit application (MIA) in respect of the Ixtaca project has not received approval. Almaden originally submitted the MIA in early 2019. The SEMARNAT resolution cites insufficient information regarding the impacts of open pit mining on the environment, local and regional area. “The Company is continuing its review of SEMARNAT’s response to the MIA and is evaluating its alternatives which include the re-submittal of a revised MIA, continuing dialogue, and legal options”.

Criscora, S.A. de C.V., a wholly owned subsidiary of TCP1 Corporation, will acquire the 1.0% NSR royalty on the Yecora project located in Sonora, for a cash payment of $1.5 M, which Maverix will receive. The ROFR on the Cristina project located in Chihuahua, was not exercised and Maverix will acquire the 2.0% NSR royalty.
  • Odyssey Marine Exploration Inc. has secured up to an additional $10 M to support its pending North American Free Trade Agreement (NAFTA) claim against Mexico.
