In the first week of November, we went to visit the Los Santos mine, one of the largest tungsten reserves in Spain, with a view to seeing current operations and discussing the other activities of the company in Spain, Australia and South Korea. The CEO of Almonty Industries (TSXV:AII), Lewis Black was on site at the time, as were staff that had worked at or visited the company’s other operations around the globe. Interestingly the staff are composed of a strong component of Portuguese mine staff, many of whom are known to the company management since the days when the Almonty team ran Primary Mining, which owned the Panasquiera Tungsten mine in Portugal.
The Los Santos scheelite deposit is in the province of Salamanca in western Spain. It is 180 km west of Madrid, 50 km south of the city of Salamanca. The drive to the mine from Salamanca is an easy one over a double carriageway most of the way through flat to lightly rolling landscape. The area around the actual mine is low hills with a mix of small holdings. The cultivation of pigs is the major industry in the region as the “capital of Jamon Iberico” is a small town nearby where the pigs fed on acorns produce this famous and costly product.
Los Santos is a large village of around 2,000 people. The mine has become quite an important feature of the local economy over the nine years it has been operating. With around 65 contract staff and tens of direct employees, the mine has a significant trickledown effect in such a small community. It is also worth remembering that unemployment in Spain is 25% at this time and has been even higher since 2008 and that in isolated rural areas it can be significantly higher. The company has strong relations with local mayors and councils. It has even established its company “canteen” in the town, rather than out at the minesite. This has effectively doubled the number of eating places in the town!
The mine is one kilometre east of the town of Los Santos and there is a newly paved road to the mine gate.
The Los Santos Mine
The Los Santos scheelite deposit was originally investigated by Billiton starting in 1979. Work undertaken included trenching and drilling. In one of the zones, Los Santos Sur, an 825m underground ramp was developed, along with level development at the 950m elevation, which provided bulk samples as well as underground drilling access. The ramp is still visible but has largely been consumed by the pit construction.
Billiton went as far as to carry out a pre-feasibility study of the prospect. By 1985, however, with a prevailing tungsten price of US$81/mtu, the project was not considered viable.
The project passed to the ownership of the ASX-listed company, Heemskirk. Under this new management the mine build began in 2008 and it was commissioned in July 2010.
The map above shows the minesite. Thus far one of the pits has been fully mined out and refilled. The blue represents the pits currently in production or planned. The two pits to the right (west) that nearly touch are intended to be combined into a sort of “super-pit” (well, not by Kalgoorlie standards) to exploit the mineralisation in the pit wall between the two existing pits.
