The proceedings against the Dirección General de Minas (DGM) are the company’s response to the cancellation of one of 12 concessions within its 4,260 ha Metates project in Durango (the largest undeveloped gold deposit in Mexico). “Chesapeake began nullity proceedings to have the cancellation of San Vicente 3 declared as null and void by the North Center III and Auxiliary Regional Chamber of the Federal Court of Administrative Justice (the “Chamber”) based on certain procedural arguments. The Chamber dismissed the Company’s lawsuit in a 2-1 split decision, with the dissenting judge finding the Company’s arguments to be well-founded. The Company plans to appeal before the Collegiate Court and to pursue all legal remedies available”. The concession covers part of the mineral resource, and its cancellation would hinder the ability to develop the Metates project as outlined on the PEA.

The Mining and Exploration News in Mexico: Highlights on the Second Week of July 2024

By Jorge Cirett
During the 28th week of the year (July 8th to July 14th, 2024), companies working in Mexico posted at least 25 press releases. One company informed on exploration advances on its property and nine companies provided operational results for Q2 2024.

Four companies released drilling results from their advanced properties, and one more completed a drilling program. Three companies announced management appointments, two the authorization for their merger and one provided information on payments to governments. ON MEXICO ISSUES, Mexico fell spectacularly on the Fraser’s ranking of mining competitiveness. Camimex pointed that exploration by the SGM just won’t work. Arcelor Mittal’s workers continue their illegal strike. ON EXPLORATION, In Sinaloa, Chesapeake Gold released drilling results on Lucy. ON MINING, Fortuna Mining, Endeavour Silver, Aura Minerals, Torex Gold, Gatos Silver, SilverCrest Metals, Orla Mining, GoGold Resources and Sierra Metals reported production results for Q2 2024.

- Camimex (Cámara Minera de México) indicated that mining exploration by the government as stated by the new mining law is just not viable. According to the new mining law, the only player able to do exploration before an auction of mining concessions is the SGM (Servicio Geológico Mexicano), and that in 2022 the SGM had a budget of just US$2.4 million dollars, compared with the annual average in the last 12 years of US$633 million dollars invested by private mining companies.
- Workers of Arcelor Mittal rejected a proposal by the company to end the more than a month and a half old illegal strike. The proposed agreement included more than US2,000 dollars per worker and 75% of the salaries not received during the strike, as well as an audit on the profits of the company for 2022 and 2023, to assess the correct application of the profit-sharing scheme in the law.
ON EXPLORATION
- Chesapeake Gold Corp. released results from the phase 2 drill program at Lucy, in Sinaloa.

The gold mineralized zone has been extended from 500 to 700 m of length, and the corridor remains open on strike and at depth. “… this expanded corridor continues to display retrograde quartz-calcite, iron oxides, sulphide veinlets and stockwork hosted within garnet and pyroxene skarn and hornfels with zones altered to actinolite and other silicates.”

- GoGold Resources Inc. is advancing the definitive feasibility study at Los Ricos South project in Jalisco. The study to be released in September focus “… towards a larger underground mine with a much smaller open pit. We have applied for an underground permit as in our view this will be more likely to be obtained on a timely basis. We see the project having more than 10 years of underground mine life, followed by a smaller open pit than originally planned in our preliminary economic assessment. The need for an open pit permit at Los Ricos South has been effectively pushed into the future more than a decade from now.”
