good afternoon Mike. On the lluvia, this was in the 1950's. It had been stripped by the diputado for copper and brass. The access road was via La Reforma. the only person living there was Chu chu Molino, one of the former owners of the LLuvia (my partner) he had a small arrastre.
Did you by any chance see the remains of the Aerial tramway they developing to send the ore down to the Fuerte river for processing?
They actually used the weight of the decending ore to turn the Ac generators to produce power, as well as to act as a dynamic brake.
As you say, the entire area is very under developed. Most tend to go where past activites were.
Have you been to the Gloria Pan ara or the Tubares zone.
K, let's talk my new freind, use some Mexican hill coffee ok? E---\_(_)p (_)p_/
