Location: This occurrence is at or near sea level, about 0.6 mile south of Baker Point and 0.2 mile north-northeast of the southwest corner of section 30, T. 73 S., R. 86 E. The location is accurate.
Geology: This occurrence consists of magnetite layers and lenses up to several inches thick in banded chert and argillite that is interbedded with a pyroxene-bearing flow or dike (Sainsbury, 1961). Deformed limestone, banded chert, and calcareous argillite crop out to the south. The rocks are probably part of the Descon Formation of Silurian and Ordovician age (Eberlein and others, 1983; Brew, 1996). Several samples collected by Maas and others (1992, 1995) contained up to 72.13 percent iron but insignificant amounts of other metals.
Workings: Only sampling by government geologists.
Age: Magnetite layers and lenses in metamorphosed, Silurian or Ordovician sedimentary and volcanic rocks.
Commodities (Major) - Fe
Development Status: None
Deposit Model: Magnetite layers in metamorphosed volcanic and sedimentary rocks.
