The Commodore Mine is near Creede, Colorado. Historically the site has been associated with the Creed Mining District which is now part of the Rio Grande National Forest. The site was first discovered in 1891 by J. C. Mackenzie, W. V. Mcgilliard. The Commodore 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 underground workings. There is one known shaft. Subsurface depth reaches a maximum of 570 meters (1,870 feet). The ore mined is composed of cerargyrite, tetrahedrite and pyrite with waste material consisting primarily of chlorite, barite and wad. The ore body extends 9 meters (29 feet) in width. Associated rock in this area is rhyolite from the Oligocene epoch 33.90 to 23.03 million years ago. The Southern Rocky Mountains physiographic province of the Rocky Mountain System characterize the geomorphology of the surrounding area.

AS AMETHYST, LAST CHANCE, AND OTHER SHAFTS SUNK DEEPER ON AMETHYST VEIN, MUCH WATER WAS ENCOUNTERED, PROMPTING FORMATION OF NELSON TUNNEL CO. AND DRIVING OF DRAINAGE TUNNEL. COMMODORE WAS TOPOGRAPHICALLY HIGHER AND DID NOT ENTER NELSON TUNNEL CONTRACT BUT DROVE ITS OWN DEEP ADIT, TUNNEL 5 (MANHATTAN ), WHICH LIES ABOUT 45 FEET ABOVE NELSON TUNNEL.

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