Trenches and drill holes into banded manganese-mineral and hematite-bearing lenses in shale, slate, and ironstone. The Spruce Top Greenstone is also exposed near the prospects, and the minerals of that formation are also listed here. Pavlides and Milton (1962) noted that there were several unknown minerals in the manganese suite of species and noted that the bementite was unusual.
