The North Home Mine
Following is a brief review of the North Home mine, the source of some of the finest North American vanadinite specimens. A more in depth article is in progress.
The North Home mine is located in the Radersburg mining district of Broadwater County, Montana. The mine explores a flattened pipelike replacement ore body in highly uplifted Mississippian Madison limestone near igneous intrusives. The early history of the mine is essentially unknown. Originally located in 1881 the mine became a small but consistent producer of gold and silver. By 1903 a $30.000 mill and several surface structures were in place. Through the early part of the twentieth century the mine was operated by lessees. In the 1930's minor mining and exploration took place. In the 1950's the dumps were sorted and several thousand tons of ore was shipped.
The North Home mine from the south. The dumps are in the upper left portion of the picture. Note the highly upturned limestone beds.
The main underground workings consist of a 500ft single compartment shaft that varies from vertical to steeply inclined on the richest portion of the ore zone, locally this shaft is enlarged by stoping. Levels had been established at short intervals to draw ore from the stopes by chutes. A single stope parallels this shaft from the surface to the bottom of the main shaft where ore mineralization ceases. Several small vertical stopes are on offshoots form the main pipe. A second shaft, the No. 2, was cut on a narrow gossan filled pipe to a depth of 175 feet, on the 100 foot level a crosscut connects this shaft to the main shaft. The No.2 shaft was mined extensively and is greatly enlarged by stoping, in places it was stoped from the 100 level to the surface. A third shaft, the No. 3, is collared a few hundred feet from the No. 2 and did not encounter ore grade mineralization. Elsewhere on the mine property there are several small pits and short adits, most of which did not get beyond daylight and none encountered ore.
The mine from the east. The large cone in the mine dump is a partially collapsed stope. The main shaft lies just beyond the cone. The No.2 shaft lies behind and to the right of the main dump. The No. 3 shaft is barely visible towards the right edge of the photo.
Looking down the main shaft. The light rope is used for lowering supplies and raising specimens.
Here is a view looking up the main shaft from the 200 level.
The No. 2 shaft. The shaft has been extensively stoped and is in poor condition but contains some of the finest wulfenite from the mine.
The No. 3 shaft. The mineralization of this shaft was not sufficient to mine, but some nice cerussite and chlorargyrite specimens have come from it's depths.
