Deposit THIS MINE WAS CLOSED JAN. 1967, AND IS IN CARETAKER STATUS. REDEVELOPMENT OF THE DEPOSIT IS UNLIKELY DUE TO THE DEPRESSED PRICE OF MERCURY. EARLIER MAS DATABASE LISTINGS WHICH INCLUDED THIS DEPOSIT WERE NAMED PROSPECT, TAGBUROS AND SUGOD AND TAGBUROS QUICK SILVER. THESE LISTINGS HAVE BEEN DELETED FROM THE DATABASE BUT THEIR MAS REPORTS HAVE BEEN INCLUDED WITH THIS DEPOSIT SEQ # 5650270016.
