About us

Minas de Aguas Teñidas SAU (MATSA) is a Spanish company that holds the rights to the Aguas Teñidas and Magdalena mines in Almonaster La Real, and to the Sotiel Mine, which is located in the municipality of Calañas, Huelva.

MATSA’s activities consist of exploration and exploitation of mineral deposits, as well as their treatment at the processing plant, located in the northern Pyrite Belt, in the municipality of Almonaster La Real, in the province of Huelva, Andalucía. This mining district is more than 250 km long and has been active for more than 2,500 years, since the time of the Phoenicians. The mines produce copper, zinc and lead concentrates for export.

MATSA's a subsidiary of TM Mining Ventures, SL, a company jointly 50% owned by Mubadala Development Company, an investment and development company based in Abu Dhabi, and Trafigura Group Pte Ltd, a market leader in the global commodities industry

The underground mining operations at MATSA are mainly exploited with the Long Hole Open stoping method and later filled with a paste, using tailings produced from the mineral treatment plant.  The modern treatment plant has the capacity to process between 4.3 and 4.6 million tonnes of ore annually and operates 24 hours a day, 365 days a year.

Approximately the 60% of the tailings produced from the processing circuits are delivered in the form of a paste (a high density, non-segregating slurry) to a tailings disposal facility, HDPE lining of this facility prevents any leakage to the outside environment. This deposit also has a bottom drainage and filtration collection system to avoid any environmental impact.

The remainder of the tailings is mixed with cement and returned to the inside of the mine from the paste plant, which is considered an important innovation in Spanish mining. Refilling the stopes with cemented paste in this way allows an almost complete exploitation of the underground deposit and reduces the environmental impact of the tailings above ground.

One hundred percent of MATSA’s outputs are destined for export, from the ports of Huelva and Algeciras.

The application of advanced technologies, such as VTEM, SQUID TEM and Titán 24, as well as a significant investment in geological research, establishes MATSA as the premier geological research company in Andalucía.
