Historical text:
Sundt: (1911)
The surface of the land is covered with earthy caliche with pebbles of decomposed green porphyry and compact black porphyry in parts. Wherever samples were taken, a conglomerate of green clayey porphyry appears, partly blocked by caliche and sometimes by the iron grit that stretches is "copper". Sometimes this iron oxide occurs in the form of veins, and has resulted in rich and abundant exploitation. as in this Colmo mine, assuring Torres, that the metals give 20 to 30 marks of silver per drawer. In some cases, a defined vein with its two metallic bodies is seen in both boxes, but the center filled with porphyry conglomerate with calichose cement.
