Comments on the production information

  • FIELD EVIDENCE SUGGESTS NO PRODUCTION. LOCAL RESIDENT STATED THAT GOLD-BEARING QUARTZ FROM ADIT WAS CRUSHED AT THE CLOSMAN WORKINGS (DEPOSIT NO. 7) AS PART OF A STOCK PROMOTION DURING THE 1930'S.

Workings at the site

  • Type of workings Underground
    Length 14.02M

Comments on the workings information

  • VEIN RANGES FROM 1.5 TO 18 IN. IN THICKNESS AND HAS BEEN LOCALLY FOLDED, WITH DEVELOPMENT OF SHARP "S" FOLD AT ENTRANCE TO ADIT. VEIN LOCALLY DIPS SOUTH.

Comments on development

  • ENTRANCE TO ADIT WAS ENLARGED DURING 1970 BY OWNER TO OBTAIN VEIN QUARTZ FOR RECREATIONAL GOLD-PANNING; ACCESS ROAD CONSTRUCTED FOR THIS PURPOSE COVERED ENTRANCE TO LOWER JOHNSON ADIT (DEPOSIT NO. 24). ; ECON.COM: GOLD DISTRIBUTION ERRATIC AND SPARCE; GOLD VALUES UNECONOMIC CONSIDERING LOW TONNAGE FOR VEIN QUARTZ
