Argentina's Glacier Mining Law Opens Supply Chain Pathways
Argentina has authorised mining activities in ecologically sensitive glacier and permafrost regions following the approval of a controversial bill. The legislation, promoted by President Javier Milei, could reshape the country's role in global metal supply chains despite opposition from environmental groups.
The law is expected to facilitate the extraction of copper, lithium and silver from frozen parts of the Andes. For procurement professionals, this development could mean access to new sources of critical minerals needed for the energy transition, though the long-term sustainability of these supply chains remains uncertain.
Argentina's 2010 Glacier Law previously prohibited all mining and exploration activities in glacier regions, protecting them as water reserves. Recent reforms have shifted responsibility for defining protected glacier areas from the Argentine Institute for Snow, Ice and Environmental Sciences (Ianigla) to provincial governments.
President Milei has supported this change, arguing it enables provinces to utilise resources within their regions. The Senate approved the bill in February 2025, with Congress providing final approval in April 2025 following nearly 12 hours of debate. The Chamber of Deputies passed the amendment with 137 votes in favour, 111 against and three abstentions.
"Attempts by foreign organisations to interfere failed, and environmentalists determined to block the progress of the Argentine Republic were defeated once again," said President Milei.
Supply chain implications for minerals
Argentina contains approximately 17,000 glaciers or rock glaciers. Glacial reserves in the north-west, where mining is concentrated, have shrunk by 17% over the last decade. Proponents of the legislation argue it is essential for attracting large-scale mining projects. According to industry forecasts, the Central Bank of Argentina estimates that the country could triple its mining exports by 2030.
"THE OBSTACLE IS OVER: WE'VE MODIFIED THE GLACIER LAW," stated MartĂn Menem, President of the Chamber of Deputies of Argentina on X.
"For years, ideological obstacles hampered the development of the provinces and blocked thousands of jobs. Today, that begins to change. It's not about the environment or development: it's about growth with clear rules, guaranteeing the protection of natural resources and respecting federalism so that Argentina can finally take off."
Supporters suggest the bill establishes clearer boundaries on mining operations, potentially allowing mining companies to operate more effectively and economically.

Investment incentives for mining companies
Luis Caputo, Minister of Economy of the Argentine Republic, said in response to MartĂn: "US$165bn in exports by 2035. Thousands of jobs. Provinces that will be forever changed."
Governors from northern Andean provinces with established mining sectors, including Mendoza, San Juan, Catamarca and Salta, have backed the bill. The previous legislation was viewed as restrictive, barring mining and industrial activity in these areas.
The reform could allow for increased investment and potentially position Argentina as a significant supplier of copper and lithium during the energy transition.
President Milei's government is attempting to attract companies like Glencore and BHP by offering tax, currency and legal incentives to mining companies. As demand for copper and lithium increases to support the broader energy transition, Argentina's resources could make it an important participant in supply chains.
Environmental concerns remain prominent
While the mining bill's approval could bring economic benefits and employment opportunities, opposition groups have raised concerns about environmental impact and water resources. Environmentalists argue the legislation will reduce the country's fresh water reserves and negatively affect its population.
Protestors outside Parliament on 8 April held signs stating "water is more precious than gold".
Activists have suggested the bill prioritises economic gain over the welfare of Argentine citizens, expressing concerns about declining water reserves and environmental damage.
"Without water, we can't even think about a growth and development project," said Congresswoman Natalia de la Sota.
The debate continues between those viewing the bill as an economic opportunity and those considering it problematic. While the legislation could support economic resilience during the ongoing energy transition, implementation without proper safeguards could create social and environmental challenges for Argentina.
