High Ore Mine

Basin, Montana

Mine Overview

The High Ore Mine is near Basin, Montana. Historically the site has been associated with the Basin-Cataract-Comet Mining District which is now part of the Deerlodge National Forest. The High Ore Mine was closed at the time of data entry with no known plans to re-open. Production size when active was considered to be small. Mine operations consist of workings of unknown type. There is one known shaft. Subsurface length extends a maximum of 7,620 meters (25,000 feet). The ore mined is composed of galena, gold and chalcopyrite with waste material consisting primarily of pyrite and quartz. Associated rock in this area is quartz monzonite from the Upper Cretaceous epoch 100.50 to 66.00 million years ago. The Northern Rocky Mountains physiographic province of the Rocky Mountain System characterize the geomorphology of the surrounding area.

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.

Understanding Claim Ownership

We receive lots of emails from people who find their name or a relative’s name on our site and want to know if this means they have some right to the land listed under that name.
Understanding BLM Administrative Areas

Whether it is filing a mine or researching one, the administering BLM office is going to be the definitive source.
Understanding Location Data

Mine handled by the Bureau of Land Management are not mapped by latitude and longitude, instead, these mines harken back to the Public Land Survey System.
Understanding Townships

A “township” can refer to two different things. Both are part of the PLSS measurement system but have different uses.
