Comments on the production information

  • THERE IS NO EVIDENCE THAT ANY CONSIDERABLE QUANTITY OF GOOD ORE WAS EXTRACTED (PUERTO RICO BUREAU OF MINES, 1941, P. 11).

Comments on the reserve resource information

  • THE WORK ON THIS PROPERTY HAS PROVEN THAT THERE ARE GOOD VALUES IN THE ORE IN CERTAIN SECTIONS, BUT DUE TO THE NARROW WIDTH OF THE VEIN THE AMOUNT OF ORE IS SMALL (PUERTO RICO BUREAU OF MINES, 1941, P. 13).

Comments on development

  • A NUMBER OF TUNNELS WERE DRIVEN, AND TWO SHALLOW SHAFTS WERE SUNK.
