The Stray Horse Mine was closed at the time of data entry with no known plans to re-open. Mine operations consist of underground workings. There is one known shaft. Subsurface depth reaches a maximum of 150 meters (492 feet) and extends 500 meters (1,640 feet) in length. The ore body is described as tabular shaped 500 meters (1,640 feet) long and 1 meter (2 feet) wide. The mineralization at this location is from the Pliocene epoch 5.33 to 2.58 million years ago.

ONE DISCHARGING ADIT WAS IDENTIFIED AT THE SITE DURING THE INVESTIGATION. THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM EXCEEDED IN THE ADIT DISCHARGE. PONY CREEK WAS FLOWING THROUGH THE CENTER OF THE SITE DURING THE INVESTIGATION. SURFACE WATER AND SEDIMENT SAMPLES WERE COLLECTED UPSTREAM AND DOWNSTREAM FROM THE SITE IN PONY CREEK. NO MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED. TEN POTENTIALLY HAZARDOUS OPEN ADITS AND FOUR OPEN SHAFTS WERE IDENTIFIED AT THE SITE.

** 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.
