Comments on the workings information

  • ADIT WHICH CUTS VEIN AT 500 FT. FROM PORTAL AND CONTINUED 700 FT. BEYOND, WHERE IT INTERSECTED DISSEMINATED MINERALIZATION IN RHYOLITE TUFF; 230 FT. SHAFT WITH CROSSCUT AT 200 FT. LEVEL, AND CROSSCUTS S AND NE FROM THE BOTTOM; 200 FT. SHAFT SUNK ABOUT 1904, DEEPENED TO 400 FT. IN 1919. THE DISSEMINATED DEPOSIT TYPE REMAINS UNDEVELOPED (1/92).

Comments on development

  • MINOR AG WAS PRODUCED FROM THE HYDROTHERMAL BRECCIAS AT THE TONOPAH HASBROUCK MINE IN THE EARLY 1900'S. DISSEMINATED AU-AG MINERALIZATION ON HASBROUCK MOUNTAIN WAS DISCOVERED IN THE MIDDLE 1970'S BY CORDEX EXPLORATION CO. FRANCO-NEVADA ACQUIRED THE PROPERTY IN THE MID-1980'S, DRILLED, AND COMPLETED FEASIBILITY STUDIES.

General comments

Subject category Comment text
Deposit TWO PERIODS OF PRECIOUS METAL DEPOSITION HAVE RESULTED IN TWO DIFFERENT BUT RELATED DEPOSIT TYPES. A HORIZONTAL, TABULAR, AND POTENTIALLY BULK MINEABLE AU-AG DEPOSIT TYPE WAS DISCOVERED BY CORDEX IN THE 1970'S. SUPERIMPOSED ON THIS DEPOSIT TYPE ARE SLIGHTLY YOUNGER HYDROTHERMAL BRECCIAS WHICH WERE MINED IN THE EARLY 1900'S. THESE BRECCIAS ARE NARROW, STEEPLY DIPPING ZONES AS SHOWN BY THE DATA GIVEN ABOVE FOR THE KERNICK VEIN.
