Tharsis Mining and Metalurgy is a Spanish mining company that owns Tharsis, La Zarza and San Telmo mines and the mining permit for the Ángeles area (Paterna del Campo), all located in the province of Huelva.

The location of these three ancient deposits (Tharsis, La Zarza, San Telmo) and ‘Ángeles’, makes Tharsis Mining & Metallurgy an attractive and valuable project. Just 50 kilometres separate Tharsis mine from the city of Huelva and its port. Key international airports are also located nearby. Seville Airport is only 130 kilometers from Tharsis, and the International Airport of Faro (Portugal) is 120 kilometers away.



To develop the Exploitation Project of Tharsis, La Zarza and San Telmo mines, carrying out the research projects and management of the environmental liability in a safe and sustainable way, generating value to Tharsis Mining & Metallurgy.

Tharsis, La Zarza and San Telmo mines are located in the Iberian Pyrite Belt, which -extending 250 kilometers by 45 kilometers – is considered one of the largest polymetallic sulphide reserves area on the planet. The features of the Iberian Pyrite Belt (extending through the provinces of Huelva, Seville, Algarve and Alentejo), have led to its exploitation since before the Roman Empire. The increasing price of metals and the growing global mineral demand during the last decade makes the Iberian Pyrite Belt a place of a great interest in mining. The existing mineral deposits in the Pyrite Belt are basically Massive Sulphides.

These old underwater deposits usually concentrate pyrite largely from which metals such as zinc, copper, silver and gold are extracted. This area, located in the southwest of the Iberian Peninsula, has frequently been a point of reference throughout history. With deposits of over 5000 years, it is estimated that the amount of treated ore exceeds 2 billion tons, and there may well be several hundred million additional tons that remain to be extracted.




Tharsis Mining & Metallurgy works under the premise of “BAT” (Best Available Technology). This implies an application of the best existing technology for mining activity, which helps protect the environment as well as the safety of each employee.
