Tharsis mine is located in the Andévalo region of Huelva. Written in the bible as Tarsis, this mine has been active for several centuries existing through different civilizations, from the ancient Phoenicians to the Roman Empire and ending one of its last golden ages in the twentieth century as a British company “Tharsis, Sulphur and Copper”(at which time Tharsis appears with the “h” for the first time).

This is Tharsis Mining & Metallurgy most singular project. With an extension of over 4,1 hectares, Tharsis mine has produced gold in modern times. Copper, gold and cobalt are potential resources of its stockwork.

1853 – 1855

Ernes Deligny discovers the mine. The French Company ‘MINES DE CUIVRES D’HUELVA’ is founded.

1879 – 1888

Mining exploitation grows. The railway line La Zarza – Tharsis is opened.

1895 – 1899

T.O.S. acquires ‘Compagnie des Mines de Cuivres d’Huelva’ and ‘Minas de Cobre de Alosno’.

1900 – 1913

T.O.S. CLOSED PART of the village of Tharsis and built “Pueblo Nuevo”. the exploitiation of ‘filón norte’ returned.

1921 – 1953

‘Filón Norte’ activity is interrupted and PIT FLOODS. gold and silver are extracted from Filón sur. Filon Norte gets drained again and begins the investigation of the area.

1953 – 1978

Investigations for Filón Centro is prepared. T.O.S. cease its activity and Compañía Española de Minas de Tharsis is created.


Mining activity ceases.


Considered one of the largest deposits of massive sulfide in the Iberian Pyrite Belt, the Zarza mine has more than 1,300 hectares. This open pit and also urderground mine produced more than 40 million tons of ore. The main extracted material was pyrite, of which – for the most part – was used to produce sulfuric acid and copper.

1853 – 1866

Discovery of the site by Ernest Deligny. Foundation of the French company Compagnie des Mines de Cuivres d’Huelva.

1879 – 1888

The concessions are leased to T.O.S. and the work of ‘Corta de los Silos’ begins – at the same time- in the eastern zone (Algaida).


1913 – 1965

Diversification and intensification of mining activity. The extraction winches nº 3 and 4 are built. A few years later, the famous ‘No. 5 winch’ and its crushing plant were built.

1970 – 1991

The exploitation slowly declines and ends in 1991 with the closing of the mine. Although the pumping of water was maintained until 1995 allowing the flooding of the pit.



After multiple changes in ownership, new investigations are carried out and an exploitation project is presented to the Administration. However, it was never developed.


It is the smallest mine of the whole Tharsis Mining & Metallurgy Project. However, it extends over 700 meters long by more than 260 meters wide. Inside the San Telmo´s area lies the ‘Santa Bárbara Este’ mass, a virgin extractive area. Located in the same volcanic belt as other currently active mines, San Telmo mine ceased its activity in 1989, after almost 100 years of exploitation. Tharsis Mining & Metallurgy is aiming to initiate an immediate start in the exploration works.

1882 – 1892

The Bede Metal & Chemical Co. leased the mine. The open-pit deposit is exploited and ends due to the decline of the copper law.

1892 – 1908

The Ybarra Family maintains the exploitation through La Hispalense. Located the largest mass of pyrite in the group.

1927 – 1929

The property returns to The Bede Metal & Chemical Co. Project failed due to the world depression of 1929.

1948 – 1954

It passes into the hands of San Telmo Ibérica Minera S.A. of Bilbao. A flotation plant of 250 tons / day is installed to produce 16% copper concentrates.

1954 – 1963

Inauguration of the extraction facilities of the Don Alfonso winch. Iniciated a 180 meters deep investigation of Santa Bárbara mass.

1963 – 1989

San Telmo ends its last period of exploitation due to the lack of market for extracted pyrite.


Former zone of mining activity that was exploited by the mythical civilization of the Tartessos through reefs rich in copper, silver, gold, cobalt and lead. Ángeles is located between the villages of Paterna del Campo, Escacena del Campo and Berrocal. It covers more than 2,500 hectares.
