The Trilby Mine is a gold, silver, and fluorine-fluorite mine located in Catron county, New Mexico at an elevation of 6,824 feet.
About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Mine Description
The Trilby mine, 2,000 feet west of the summit of Fanney Hill, has long been idle and was inaccessible at the time of visit. At the shaft the vein, which is not prominent along the outcrop, follows the contact between Fanney rhyolite and Last Chance andesite, which strikes a few degrees north of west and dips steeply to the north. West of the shaft the Fanney rhyolite of the footwall is overlain by the Last Chance andesite. The vein may be the eastward extension of the Johnson vein, but the connection along the outcrop could not be established.
The shaft dump shows abundant coarse calcite with some quartz and fluorite, and, according to Scott the west end of the vein is notable for the quantity of fluorite it contains.
The development work consists of a 250-foot inclined shaft with a small amount of lateral development.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.
