Galore Regularizes Concessions, Secures Dos Santos Project Ruling

The strategic regularization of 6 concessions and a favorable court ruling for the Dos Santos project highlight the critical importance of rigorous title defense under Mexico’s evolving mining regulations. With federal authorities intensifying enforcement of statutory compliance regarding duty payments and statistical reporting, establishing legal certainty is vital for maintaining active mineral titles. This regulatory environment directly impacts exploration juniors, legal counsels, and institutional investors navigating asset preservation within the Mexican extraction sector.

Canada-based Galore Resources announced a regulatory and legal update for its Dos Santos Project in Zacatecas, following the completion of an independent legal title review by corporate counsel RB Abogados on May 7, 2026. The company successfully regularized six concessions and advanced multiple administrative and judicial proceedings to defend its mineral property interests.

The regularization of the six concession titles was achieved through the payment of outstanding concession duties current through 1H26. This regularized portfolio includes the Carbonerillas identified by title 218125, San Jose (Title 218126), Los Gemelos I (Title 216788), Duende 4 (Title 218328), Duende 5 (Title 218329), and Duende 7 (Title 226581) concessions. Financial support to maintain these mineral assets was provided via an infrastructure arrangement with an existing shareholder.

The title review also detailed several ongoing legal actions regarding contested concessions within the project area. For the 9,761ha Santa Fe 3 concession (Title No. 233935), which houses the La Palma principal exploration target, the Federal Administrative Court issued a favorable judgment. 
Galore Resources had filed a nullity action contesting a Mar. 7, 2025, cancellation by the Mexican Mining Bureau (MMB) over unpaid duties, citing a lack of official non-payment or cancellation notices. The company is currently awaiting administrative implementation of the court's ruling before the Public Registry of Mines (PRM).

Meanwhile, administrative appeals before the MMB and an annulment demand before the Federal Administrative Court remain pending regarding the June 26, 2024, cancellation of the Santa Fe 4 Fracc. 2 concession (Title No. 233865). Similar to the Santa Fe 3 case, the company alleges it received no official notification before the administrative cancellation.

RB Abogados also identified that a third party had registered the Los Gemelos I and Duende 7 titles under its own name using falsified documentation filed with the PRM. Legal counsel confirmed that the original June 7, 2011, assignment agreement between Galore Resources' subsidiary, Minerales Galore, and Ezequiel Agüero Zamudio remains valid and enforceable. Backed by a favorable court judgment from June 30, 2025, regarding prior registration denials, the company is consulting with the MMB and PRM to clear the registrations administratively ahead of planned litigation.

Administrative Oversight and the Enforcement of Existing Regulations
The administrative and title defenses undertaken by Galore Resources materialize amid a push by federal authorities to systematically enforce compliance parameters within Mexico's extraction sector. On Feb. 17, 2026, MBN reported that the federal government carried out a massive administrative sweep, recovering 889,512ha of land through the cancellation of 1,126 mining concessions that were found to be non-compliant.

At that time, Minister of Economy Marcelo Ebrard stated that the administration was reviewing concessions to identify assets that were not contributing to productive activity. "Many of these concessions were granted to individuals for the sole purpose of speculation, compromising a significant amount of land. A concession should be for investment, not for speculation,” Ebrard said.

The primary legal grounds for these cancellations included a two-year delay in the payment of rights and the failure to submit required statistical and work reports. According to Fernando Aboitiz, Head of the Unit for the Coordination of Extractive Activities, Ministry of Economy, the absence of these reports indicates that the concessions were idle and serving speculative interests rather than mineral development.

According to Joel González, Senior Partner, ALN Abogados, these widespread cancellations stem primarily from a long-delayed application of statutory rules rather than the creation of new legal mandates. González noted that the General Mining Agency had historically deferred enforcement of key reporting provisions, allowing companies to pile up multi-year non-payment backlogs without facing immediate regulatory consequences. The current administrative paradigm represents a structural correction where federal oversight bodies are directly enforcing pre-existing statutes regarding surface rights payments and annual statistical filings.

This shift in executive policy places heightened operational pressure on exploration juniors, transforming routine corporate documentation into a critical mechanism for title defense. In an MBN Expert Contributor piece, Santiago Suárez, Partner, Servicios Legales Mineros (SLM) detailed that the initiation of cancellation proceedings does not necessarily entail the definitive loss of a mineral asset. Under the framework of the Mining Law and the Federal Administrative Procedure Act, concessionaires can deploy specialized defense strategies to reverse administrative determinations. 

Suárez emphasized that public declarations by the federal government regarding recovered"concessions do not preclude the availability of legal remedies. Operators can challenge administrative actions through administrative review procedures, contentious-administrative proceedings before the Federal Administrative Justice Court, and federal amparo injunctions. Because individual concessions involve highly distinct legal and factual variables, tailored case-by-case due diligence remains essential to initiate litigation and achieve the effective restitution of canceled mineral rights.
