A large multi-compartment shaft sunk to increase the capacity of the mining operation, which exceeded the capacity of the Parker shaft. This was the final shaft sunk on the ore body and remained active until permanent closure of the mine. It was sunk in the gneissic rock to the W of the Franklin Marble and the ore body. Some small cavities were encountered during the sinking process, containing zeolitic mineralization.

Middle Cambrian - Early Cambrian
501 - 541 Ma

ID: 2895063
Leithsville Formation

Age: Cambrian (501 - 541 Ma)

Stratigraphic Name: Leithsville Formation

Description: (Wherry, 1909) - Thin- to thick-bedded dolomite containing subordinate siliciclastic rocks. Upper part is medium- to medium-dark-gray, fine- to medium-grained, pitted, friable, mottled and massive dolomite. Middle part is medium-gray, stylolitic, fine-grained, thin- to medium-bedded dolomite that is interbedded with shaly dolomite and, less commonly, vari-colored quartz sandstone, siltstone, and shale. Lower part is medium-gray, medium-grained, medium-bedded dolomite containing quartz-sand grains in stringers and lenses near the contact with the Hardyston Quartzite. Archaeocyathids of Early Cambrian age suggest an intraformational disconformity separating rocks of Middle and Early Cambrian age (Palmer and Rozanov, 1976). Thickness approximately 305 m (1,000 ft).
