Deposit: Massive black Mn oxides and mixed black oxides and fine-grained silica occur in a 0-2 m thick bed in the pennsylvanian havallan sequence. The unit is obviously stratabound and of submarine exhalative origin. Bedding strikes n20e, 60 nw. The Mn-rich bed lies between lt gray chert units. Within 1 m of the Mn bed on both top and bottom, the gray chert contains bands and irregular areas of red chert (jasper).
Development: Several claims staked and explored for mercury in this area between 1956 and 1961 by w.e. Simpson, virgil olson, joe mckenzie, and walter polkinghorne.
