A uranium-RRE deposit in a semi-basic pegmatite, located near Cranberry Lake. Owned by the Byram Exploration & Mining Co. (BEMCO), Inc. Workings are comprised of shallow open cuts, a shaft and a raise with an inclined haulage way.
The BEMCO Mine uranium/rare earth deposit was discovered during the uranium rush of the 1950βs. With little governmental interference and no NIMBYβism a short adit, sloped downward, guaranteeing flooding of the inner end, and a very short raise to the surface were driven into the hillside. On top of the hill a shallow trench was excavated on the outcrop. When I first saw this site, circa 1958-9, I remember guys with geiger counters taking readings, making notes and hammering off samples. By the early 1960βs , after diamond drilling failed to indicate any down dip extension, activity ceased. Once, when I was there in the late 60βs or early 70βs I encountered 2 of the original owners/workers, puttering around. I canβt remember if they told me why. Whatever it was nothing came of it.
More recently the area became part of Allamuchy State Park. The uranium mine was rediscovered by the local population. In the changed social climate radiation hysteria took hold and the State backfilled the adit and placed steel bars over the raise.
The Bemco deposit is described by Vassiliou (1980). A thin, magnetite-rich band containing zircon and rare earth minerals occurs at the contact between a pegmatite dike and the enclosing sulphidic pyroxene gneiss. A variety of minerals have been attributed to the BEMCO mine but only magnetite and black zircon, enclosing cores of fergusonite and uranothorite, are common. Jaffe and Molinski (1962) described spenceite, now tritomiteβ(Y), the second occurrence of this species.
There are a number of magnetite plus U/REE deposits scattered through the Reading Prong Highlands. The best known is the Doverite-bearing occurrence in the Scrub Oaks Mine. There is a widespread intimate relationship between these U/REE β bearing magnetite concentrations and pegmatites (Volkert, et al, 2005). U-Pb ages range between 990 and 940 MA.
