Mining facilities include an <br />excavated portal access area, conveyor structure, mine ventilation system, water tank and pump house, <br />maintenance building and ancillary facilities. Most of the infrastructure remains in place and the portals are sealed. <br />The maintenance and ancillary facilities on the north end are not well maintained. Equipment from the reclaimed <br />Williams Fork site has been relocated and stored in the Sage Creek Mine facility area for possible future use. Over <br />the years, some equipment has been removed and utilized at the nearby Foidel Creek mine. <br /> <br />SIGNS and MARKERS – Rule 4.02 <br />Mine and Permit Identification Signs 4.02.2, Permeter Markers 4.02.3, Stream and Buffer Zone Markers 4.02.5, <br />Topsoil Markers 4.02.7 <br /> A mine sign was in place at the site entrance which included the mine name, operator name, address, <br />phone number, DRMS permit number (Photo 1).
