Using information that bikers usually give me, I was able to find it, but it was difficult because it is still a disaster area. The mine is very close to Can Montsant and although its name mentions gold, copper was extracted as J. M. indicates.
I was inside the mine, which is barely twenty meters deep. There are also remains of tunnels through which they supposedly extracted more mineral. What I was most interested in was finding some mineral samples, but I only found a few small pieces of malachite. As I said, it was very difficult to find it, getting into brambles and ending up covered in cuts everywhere. I tried to go somewhere else and when I passed a mound I found some samples of malachite. As it was already late and the heat was pressing, I left it for another day. A few months have passed and a few days ago I came back with better weather. I found more samples of malachite in quartz, but no trace of azurite. Well, I guess it's malachite, although I'd like some pieces to be turquoise in color, haha, but anyway, to me they're very interesting and pretty. Regards.
