By Jorge Cirett

During the 15th week of the year (April 11th to April 17th, 2022), at least 30 press releases were announced by companies working in Mexico. To note, nine companies posted exploration advances on their properties, six released first quarter 2022 reports, one updated on project work, six reported drill results on their advanced properties and one signed an exploitation agreement on a small scale mine. ON MEXICO ISSUES, Mexico’s president Andrés M. López Obrador warned he will change the mining law to make a government’s monopoly on lithium, if his Energy bill is not approved. According to Miner Deck, three of the top ten gold intercepts on the second week of April were drilled by companies working in Mexico. Six of the top ten silver intercepts were by companies in Mexico. ON EXPLORATION, in Sonora, Tocvan Ventures provided drill results on the Pilar project; Infinitum Copper released trench results at La Adelita; Silver Spruce had the preventive report approved for drilling at Diamante; Reyna Gold started drilling at La Gloria; Aztec Minerals finished the phase 2 RC drill campaign at Cervantes. In Chihuahua, Reyna Silver released drill results from Batopilas. In Nayarit, Sierra Madre Gold and Silver released drilling results from Tepic. In Guerrero, Pantera Silver reported drill results from Nuevo Taxco. In Zacatecas, Defiance Silver completed drilling at the Lucita prospect in its Zacatecas Silver project. ON MINING, Endeavour Silver, Fortuna Silver, Avino Silver, Golden Minerals, Great Panther and Torex Gold released first quarter 2022 reports.
