  • Mexico’s president Andres Manuel Lopez Obrador, on his daily conference while speaking on the proposed energy bill that includes the nationalization of the (non-existent) lithium industry, said that the Mexican government is to create a company for lithium extraction. With an anti-neoliberalist overtone and speaking of sovereignty, he affirmed lithium is owned by the Mexican people, and that no foreign countries are to have it.
  • Fortuna Silver Mines Inc. received in December 17, 2021, a 12 year extension on its environmental impact authorization for the San Jose Mine in Oaxaca. On January 28, 2022 received a notice form SEMARNAT stating a typographical mistake, by which the term of the permit would be reduced from twelve to two years. Minera Cuzcatan (Fortuna’s subsidiary) “has initiated legal proceedings in the Federal Court to challenge and revoke said typographical error and to reconfirm the 12 year extension period granted by SEMARNAT in December 2021”.


  • Benjamin Hill Mining Corp. announced the commencement of the maiden drill program at its Sonora Gold property in Sonora. The drill rig is currently working on the fourth of 34 planned holes on the Sonora Copper, Caracahui, El Fierro and La Salada areas. A 10,000 m induced polarization and resistivity geophysical survey covers the Sonora Copper, El Fierro, Caracahui, El Crestado, El Tanque, Las Antenas and La Salada areas. Benjamin Hill Mining paid a posthumous tribute to its Special Advisor David Jones: “He shared his knowledge and experience freely to the profession and to society, with honest exuberance to advance the development of economic projects, boosting local economies in the Americas and the around the world. Some of his projects have become mines that have positively impacted our world, socially and economically, proving himself one of the best economic geologists of modern times”.
  • Tocvan Ventures Corp. released surface sample results from its Pilar project in Sonora. Of 59 samples, 21 returned over 0.5 gpt Au, defining several new areas to be drilled. The Main Zone was expanded with up to 9.2 gpt Au, 279 gpt Ag in a silicified quartz vein breccia, the 4-T Trend was extended to the southeast with values of up to 6.6 gpt Au, 433 gpt Ag and a new vein corridor over 200 m long is highlighted by samples of up to 523 gpt Ag, 1.3 gpt Au and additional mineralization 300 m to the south returned up to 3.1 gpt Au, 27 gpt Ag.
  • Southern Empire Resources Corp. updated on drilling of the Pedro project in Durango. Three holes have been completed totaling 421 m, and a fourth is in progress. Core review “suggests zones of up to 70 m of moderately silicified, limestone dominated conglomerate with zones of up to 20 m (core length) exhibiting disseminated and vein controlled arsenical minerals including orpiment and realgar”. Historical drilling by Newmont produced intervals of up to 5.55 m @ 0.59 gpt Au.

At its Plomosas mine in Chihuahua, 3,140 tonnes were mined, 5,099 tonnes brought to the surface and 4,592 tonnes processed, grading 13.4% Zn, 7.1% Pb, 41 gpt Ag, recovering 77.1 % Zn, 37.8% Pb, to produce 377 tonnes Zn, 112 tonnes Pb in concentrate. The mining rate was affected by the flooding of stopes related to failures on pumping and generator equipments. “Access to the under-water stopes should be re-established during February 2022”. The company continues with the exploration of the Mina Mexico and the Juarez mine prospects within the project area.
  • Guanajuato Silver Company Ltd. presented production numbers on the last two months of 2021 and exploration highlights at El Cubo and Pinguico properties in Guanajuato. During November and December 2021, 238 K Oz AgEq were produced, resulting from the mining of 76 K tonnes from El Cubo and the El Pinguico above ground stockpile, of which 33 K tonnes were milled in December. Metallurgical recoveries for material from Pinguico averaged 74% Au, 72% Ag. The company completed 6,800 m of drilling at El Pinguico and El Cubo, and plans to complete over 22,000 m in 2022.
