Comments on development

  • CU-STAINED TACTITE OUTCROPS ORIGINALLY PROSPECTED FOR COPPER AND SILVER, BUT PROBABLY NO ORE WAS SHIPPED. OLD WORKINGS RE-DENOUNCED BY FERNANDO NAVARRO AND PABLO RAMIREZ IN JUNE 1943 WHEN SCHEELITE WAS FOUND ON OLD ORE DUMP. DEVELOPMENT WORK CONTINUED UNTIL END OF 1943, BUT ATTEMPTS TO MINE THE HARD, DENSE TACTITE BY HAND METHODS WERE UNSUCCESSFUL.
