Development
SOME YEARS BEFORE 1920, S. R. HEISHMAN PUT DOWN A LARGE HOLE ON THE UPPER WEST SLOPE OF THE SOUTH END. PROSPECTING AROUND 1920 WAS DONE ON THE SOUTH END OF THE RIDGE AND AT OTHER PLACES BY ALEXANDER FLEMING AND OTHER PARTIES. NO COMMERCIAL DEPOSITS OF MANGANESE ORE WERE FOUND.
Workings
A NUMBER OF PITS WERE DUG DURING PROSPECTING. THE HEISHMAN PIT WAS CAVED WHEN STOSE AND MISER VISITED IN 1920, BUT STILL WAS 3 M (10 FEET) OM THE NEW SCOTLAND LIMESTONE.

Footnotes
* Mine bounds on map indicate the general area that a mine occupies. For an detailed map, refer to the overseeing BLM field office.
** The mine central point is based on an average of the mine's bounding box(es) and does not necessarily fall on the claim itself.
1 World-class significance is determined by total endowment of the contained commodity. This includes all past production and remaining reserves. Each commodity is considered separately and commodities cannot be combined to arrive at a significant size. The tonnage thresholds are from the mine model grade-tonnage studies. As of June 2008, many entries were classified as significant under less strict rules.

A “township” can refer to two different things. Both are part of the PLSS measurement system but have different uses.
Deposit
PIT DUG BY HEISHMAN EXPOSED BRECCIATED CHERT CEMENTED BY MANGANESE ENCLOSED IN DARK WAD SOIL. A FEW FRAGMENTS OF HARD ORE WERE EVIDENT IN 1920. ON THE UPPER SOUTH SLOPE OF THE RIDGE, CHERT AND SANDSTONE FRAGMENTS IMPREGNATED WITH MANGANESE COVER THE SURFACE. THE PITS OF LATER PROSPECTING PENETRATED CHERT, SAND, AND SANDY CLAY, WHICH ARE RESIDUAL FROM THE NEW SCOTLAND LIMESTONE.
