Law 5805 of the Province of Río Negro, published in the Official Gazette of Rio Negro on September 1, 2025

This law establishes a regime that requires operators in the hydrocarbon, mining, and energy sectors—as well as all projects executed under Law 27742 (Incentive Regime for Large Investments)—to prioritize suppliers from Rio Negro. These suppliers must be defined and certified through a public registry.

Subjects included in the Law must ensure that at least 60% of the goods, services, and works they purchase or hire during the various stages of the project are provided by suppliers registered in the Rio Negro Suppliers Registry.

The enforcement authority may request reports, conduct audits, verify compliance, and carry out inspections. Non-compliance with the provisions regarding hiring Rio Negro suppliers may result in warnings, fines, and loss of tax benefits.

“Mendoza projects annual OPEX of USD 100 million in exploration and over USD 20 billion in exploitation,” published by Mineria y Desarrollo on September 26, 2025
 

Mendoza’s Mining Director Jeronimo Shantal announced at PERUMIN 37 that the province expects an annual OPEX of USD 100 million for exploration and over USD 20 billion for mining exploitation, based on its current project portfolio.

“In the first stage of the Pilares Plan, which includes four exploitation projects plus Potasio Rio Colorado and over 100 exploration projects, Mendoza would generate an annual OPEX of approximately USD 100 million in exploration. In terms of exploitation, the combined projects exceed USD 20 billion,” he stated.

Shantal highlighted that two copper mines could begin operations within the next two to three years. Additionally, exploration activities in uranium, lithium, and rare earth elements further position the region as a hub for critical minerals. The PSJ Cobre Mendocino project, for example, anticipates an investment of over USD 600 million and the creation of approximately 3,900 direct and indirect construction jobs, along with around 900 operational jobs.
