Models of the ore deposits

	Figure 9-8. The Franklin orebody. A precise scale model generated by the engineers of the New Jersey Zinc Company. The irregular opening at the top edge represents the area of the orebody weathered during the Precambrian. The fold and the relative shortness of the east limb are apparent at the left. The thickened keel is evident at the bottom. The model is 21.25 inches (53 cm) in length and the scale is 1 inch (2.5 cm) = 200 feet (61 meters). Photo by Vic Krantz.

Geologists of the New Jersey Zinc Company prepared models of both orebodies. The model of the Franklin orebody is solid, painted bright red, and was constructed painstakingly by mining engineers using the mapped vertical sections of the orebody. This model is in the Franklin Mineral Museum in Franklin (Figure  9-8).

There are four models of the Sterling Hill orebody. One, a vertical mining-model, was constructed in 1958-1961. A second model, depicting the geology on all the mine levels, on glass plates, and in color, was created by Robert W. Metsger and John Teet in the late 1950’s. Both of these models, which are substantial in size, are in the State Museum in Trenton, New Jersey. A third model, of the north orebody at Sterling Hill, is in the Sterling Hill Mining Museum, as is a small general model built under the supervision of Allen Pinger.
