ON MEXICO ISSUES

  • Equinox Gold Corp., announced that the community blockade at its Los Filos mine in Guerrero has been lifted and access to the mine has been restored. Los Filos has commenced a staged restart and workers will resume their duties only after testing negative for COVID-19.
  • First Majestic Silver Corp., announced its intention to appeal the Circuit Court decision to nullify the Advance Pricing Agreement concluded in 2012 between Primero Empresa Minera SA de CV (PEM) and the Mexican tax authority, Servicio de Administracion Tributaria (SAT).   “The Federal Court’s decision directs SAT to re-examine the evidence and basis for the issuance of the APA with retroactive effect, for the following key reasons: (i) SAT’s errors in analyzing PEM’s request for the APA and the evidence provided in support of the request; and (ii) SAT’s failure to request from PEM certain additional information before issuing the APA. The Company’s legal advisors having now reviewed the written reasons continue to be of the view that the Federal Court’s decision is flawed both due to procedural irregularities and failure to address the relevant evidence and legal authorities. The Company intends to appeal the decision to the Circuit Courts by the December 1, 2020 deadline”.
  • Deputies of the mining commission of the State Congress and the State Secretariat of Economy will join forces to request to the Federal Government that the Mining Fund returns to the Municipalities of the Sonora State. The commission reported that the Federal Government has pending the contribution of MXP $1,500M corresponding to fiscal year 2019 to be exercised in fiscal year 2020 in works of high social impact in municipalities with mining activities. One of the deputies stated that the resources of the Mining Fund originated in the State of Sonora, must remain here, because it is a resource of Sonora and must be applied, definitely, to the needs of the State. Sonora ranks first in the country in the extraction of copper, gold, molybdenum, wollastonite, and graphite and second in silver, substances that are exploited by national and foreign companies with investments around the world.
  • Great Panther Mining Limited has temporarily suspended the operations at its Topia mine in Durango due to the detection of COVID-19 among the workforce.   A reduced workforce will remain on site to maintain essential activities for the duration of the voluntary suspension. The health and safety of employees, contractors, and host communities remains a priority.  The company will continue working closely with the local government and regional health authorities to ensure a safe restart of normal operations.
