The Office of the United States Trade Representative (USTR) and the Government of Mexico jointly announced a formal course of remediation on Friday, October 23, 2026, targeting the Minera Peñasquito facility in Zacatecas, Mexico, under the United States-Mexico-Canada Agreement (USMCA) Rapid Response Labor Mechanism, Mexico Business News reported, and the announcement is listed on USTR's official October 2026 releases page.

The action stems from a petition submitted by the National Union of Mine, Metal, Steel and Related Workers of the Mexican Republic (Los Mineros) to the Interagency Labor Committee for Monitoring and Enforcement (ILC). The petition alleged that the company retaliated against workers for union activity, including through dismissals — allegations, not proven findings — and the United States earlier invoked the mechanism to ask Mexico to review whether workers at the facility were being denied the rights of freedom of association and collective bargaining.

Under the agreed remediation framework, the corrective measures include the dissemination of official neutrality statements, anonymous complaint mechanisms, and mandatory in-person training sessions during regular working hours, Mexico Business News reported. The Rapid Response Labor Mechanism also expects proactive internal compliance audits and robust grievance procedures for industrial operators in Mexico.

MLex also reported on Friday that the US and Mexico have reached an agreement over the allegations that Minera Peñasquito retaliated against workers for protected union activity, confirming the USTR announcement through a second independent report.

The Peñasquito facility, operated by Minera Peñasquito, S.A. de C.V., a Newmont company in Zacatecas, produces gold, silver, lead and zinc, according to USTR's earlier review request. When the United States first invoked the mechanism in this case, it also suspended liquidation of unliquidated entries of goods from the facility into the United States, USTR said at the time.
