* 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.

COMPAGNIE DE TIFNOUT TIRANIMINE. AT BOU AZZER, PLANS (AS OF 3/75) ARE FOR COBALT OUTPUT TO REACH 8, 000 MTPY BY 1977. CONCENTRATOR 1972 FEED CAPACITY WAS 180, 000 M. T. P. Y.
DEPOSIT OCCURS IN AREAS OF PRECAMBRIAN ROCKS EXPOSED BY THE EROSION OF AN ANTCLINE OF YOUNGER ROCKS. THE TOTAL LENGTH OF OUTCROP, 35 MILES, 3 TO 9 MILES WIDE. THE OLDEST OF THE PRECAMBRIAN ROCKS ARE DIORITE AND A SERIES OF MICA SCHISTS AND GNEISS. YOUNGER THAN THESE IS A COMPLEX OF SERPENTINE AND OLIVINE BASALTS. THE ORE OCCURS IN VERTICAL EAST-WEST VEINS OR VEINLIKE MASSES AT OR NEAR THE CONTACT OF THE SERPENTINE AND THE DIORITE; MORE OF THE VEINS LIE IN THE SERPENTINE THAN IN THE DIORITE. VEINS HAVE MAX. WIDTH OF 5 FEET AND HAVE BEEN MINED TO 575 FEET IN DEPTH. OXIDATION HAS PRODUCED MINABLE AMOUNTS OF ERYTHRITE, ANNABERGITE, AND BLACK OXIDES. ORES ARE REPORTED TO CONTAIN 3 TO 300 GRAMS (0. 1 TO 9. 6 OUNCES) OF GOLD PER MET. TON, AND UP TO 50 GRAMS (1. 6 OUNCES) OF SILVER PER MET. TON, (U. S. BUR. MINES, MATERIALS SURVEY: COBALT, REFERENCE #3 ). BECAUSE CO IS THE PREDOMINANT MINERAL HERE, AND THERE IS A LACK OF ASSOCIATED METALS, ECONOMIC MINING REQUIRES A HIGER TENOR OF COBALT ORE THAN.
USUAL, AND FOR THESE REASONS, MINED ORES CONTAIN BETWEEN 1 AND 2 PERCENT COBALT.
