The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Production): DEVELOPED DURING WWI - SOME ORE WAS PILED ON THE DUMPS BUT NONE WAS SHIPPED. FIVE OR TEN TONS ON THE DUMP SHOULD RUN OVER 40 PERCENT MANGANESE. MR. L. W. JONES, FORMER OWNER AND DEVELOPER OF THE PROPERTY, STATES THAT ASSAYS OF SAMPLES TAKEN DURING WWI RAN 48 PERCENT MANGANESE AND 6 PERCENT SILICA.

Comment (Workings): SHAFT 30 FT. DEEP FROM WHICH AN OPEN CUT 20 FT. LONG RUNS S. 35 DEG. E. A DRIFT. 4 FT. WIDE AND 12 FT. LONG HAS BEEN RUN TOWARD THE WEST FROM THE SHAFT

Comment (Geology): GEOL.DESC: MASSIVE, MANGANIFEROUS META-CHERT; ORE IS CHIEFLY BOTRYOIDAL AND NODULAR PSILOMELANE WITH SOME PYROLUSITE. THE MASSIVE METACHERT IS ENCLOSED IN RHYTHMICALLY BEDDED METACHERTS; BEDS 1 IN TO 3 FT. THICK; SEPARATED BY ORIGINAL SHALY PARTINGS; AT LEAST 50' WIDE.
