After driving an hour through a dry river bed ('ramblas'), we drove up a hill to look into the valley where the mine should be located. But nothing to see there and the road into the valley was blocked by rocks. The road on the right side of the valley does not reach the mine, and cannot be reached from this side of the valley so we had to return to the ramblas and try it from the other (left) side. The mine proved to be on the left side of this valley behind the first ridge
