In a statement, the Mining Union indicated that the conflict occurred after a group majority of workers from Minera Del Norte and AHMSA decided to abandon the organization headed by Gómez Urrutia to join the National Democratic Union of Miners, and he has responded the same as he did in Zacatecas, Guerrero, Sonora and other areas, generating violence and stopping the activities of the mining companies. Minera Del Norte is the main iron extraction company in the region; all the material extracted by the workers is sent to Monclova through a 300 kilometer railway, for use as an input in the AHMSA smelting furnaces.
ON EXPLORATION
- Prismo Metals Inc., released trenching sampling results from its Los Pavitos project in Sonora. Highlights assays include ZA2 (Auras Zone) with 2.2 g/t Au and 23 g/t Ag over 19m long, including 10.3g/t Au and 104 g/t Ag over 4m long; ZSC9 (Santa Cruz Zone) with 0.5 g/t Au over 8m long; and ZSC10 with 2.3 g/t Au and 13 g/t Ag over 7.8m long. The company intends to explore these mineralized zones by drilling, planned to commence shortly.
- Colibri Resource Corporation outlined mineralized structures on the Banco de Oro and Bonancita target areas at its the Plomo project in Sonora. At the Banco de Oro target, the mineralization consists of brecciated quartz veins hosted in foliated sericitized and pyrite bearing rhyolites. Recent geological mapping and sampling has covered an area of approximately 41 hectares, extending approximately 500m north of the historic Banco de Oro mine. Gold values were detected in 46 of the 64 analyzed samples, of which 14 samples returned >0.1 g/t Au, with a high grade of 1.45 g/t Au. At the Bonancita target, mineralization consists of four prospects, all of which contain historical assays from outcrop samples returning > 1 g/t Au. Three of the prospects, Bonancita, Bonancita NWI and Bonancita NWII form a NW trend approximately 2 km in length which is coincident with both a strong topographic lineament and with a strong, NW trending, regional scale magnetic gradient lineament. The recent geological mapping and sampling was conducted on the southernmost prospect, where the objective was to evaluate a NW mineralized trend defined by historical sampling including a high value of 7.62 g/t Au. The exploration program covered over 60 hectares and a total of 75 samples were collected for gold analyses, of which 15 samples returned > 0.1 g/t Au and 3 returned > 1 g/t Au with a peak value of 2.72 g/t Au.

The San Martín mine in Zacatecas owned by Industrial Minera México SA de CV, a subsidiary of the Americas Mining Corp. branch of Grupo México, has a labor complaint issued by the United States government, for denying workers the right to syndical freedom. The petition alleges the violation of the United Steelworkers and the National Union of Mining, Metallurgical, Steel and Similar Workers of the Republic of Mexico (Los Mineros)’ rights as a holder of the collective bargaining agreement at the San Martín mine and the hiring of workers to replace striking workers in violation of the collective bargaining agreement and Mexican law. The US government investigation revealed evidence of violations of the Los Mineros’ collective bargaining rights that warranted a request for review under the USMCA.
- Newmont Corporation suspended operations at its Peñasquito mine, in Zacatecas, after the workers’ union announced the strike. The reason for this conflict is a fight over a profit-sharing agreement, the miner said in a statement.

- Heliostar Metals Ltd., issued a press release to clarify certain of its previous disclosure regarding its Ana Paula project in Guerrero. The Company previously disclosed statements which could constitute an economic analysis of its intended re-scoping of the Ana Paula Project. The Company wishes to retract the Disclosure. The Company has not completed an economic analysis on the re-scoping of the Ana Paula Project and the Disclosure is not supported by a technical report in compliance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects. The Company advises readers not to rely on the Disclosure.
- Prime Mining Corp., filed a technical report for its Los Reyes project in Sinaloa, for the updated mineral resource estimate (MRE) reported on May 2, 2023. The addition of 100,000m of Prime drilling has doubled the current MRE compared to the April 2020 resource. The table below shows the updated open pit 2023 MRE:
The MRE has a high-grade open pit mill resource and a lower grade heap leach portion. The MRE includes drilling completed before December 31, 2022 from only the three main zones at Los Reyes: Guadalupe, Z-T and Central.
