Polymetallic veins with high-grade gold and silver, plus copper, lead and zinc, in the Iglesia Department: 68 diamond drill holes, 9,944 m drilled and grades certified by ALS laboratories. Project available for investment.
Fuentes Minerales · mining in San Juan since 1968, with bentonite and diatomite in production. View portfolio
Two industrial minerals already in production, and two projects open to investment — all based in San Juan.
Ten mining rights with polymetallic silver, gold, copper, lead and zinc veins in the Iglesia Department. 68 drill holes with intercepts of up to 49.8 g/t Au and 1,290 g/t Ag. Public information and Virtual Data Room access.
Sodium bentonite land and mining concessions in Angualasto, Iglesia Department, with joint ownership of land and mineral rights — the same land where the bentonite currently produced comes from, with additional surface open to new investment.
Sale of high-quality white sodium bentonite for industrial use: drilling muds, foundry, waterproofing and more.
Sale of high-purity siliceous diatomite (diatomaceous earth) for industrial use: filtration, paints and plastics, animal feed and pest control.
Looking to buy bentonite or diatomite? We produce and sell both minerals from our own deposits in San Juan, Argentina (Iglesia and Ullum departments). Ask about availability, volumes and commercial terms.
Exceptionally white sodium bentonite (montmorillonite), studied in international scientific publications. Tyler 200 mesh retention: 98.7%; pH 8; moisture 7%. Used in drilling muds for oil and gas, foundry and metallurgy, waterproofing and sealing, and in the food and pharmaceutical industry.
Diatomite, also known as diatomaceous earth, of high siliceous purity (77.1% SiO₂), mined from our own deposits in the Iglesia and Ullum departments. Used in liquid filtration, as a mineral filler in paints and plastics, in animal feed and in pest control.
Besides industrial minerals, the Fuentes family develops El Fierro, a gold, silver and copper mining project in the Iglesia Department, and La Chigua, a 50,000-hectare estate with bentonite concessions.
The Fuentes family's history in San Juan mining spans three generations of dedication, strategic vision and constant work. What began as a passion discovered by Víctor Heriberto Fuentes, firmly backed by his son Víctor Guillermo, today stands as a professional, technical structure built for future growth, led by Fernando Fuentes.
Begins working the Alto del Colorado deposits, with diatomite.
Acquires the Cerro de la Luna diatomite deposit.
Acquires the Don Juan, Siete Hermanos and Malimán bentonite deposits.
Acquires the El Fierro exploration claim.
La Chigua's 50,000 ha are formalized.
Fernando Fuentes continues and develops the legacy.
We understand mining work as a labor of patience, persistence and maximum precision. For decades, our family meticulously documented the geological potential of the region. Today, we combine that valuable historical archive of technical knowledge with modern technology and standards, ensuring responsible, efficient management of the mineral resource.
We work on the value creation, optimization and commercial development of San Juan's bentonite and diatomite deposits, aimed at meeting demand from a range of national and international industries.
We drive the exploration and development of "El Fierro", a polymetallic vein project in the Iglesia Department.
