The documentation included a re-run of geo-chemical analysis of ore <br />and waste rock and a map of the radiometric survey of the mine portal area. No additional issues have been identified <br />with the submitted data. The data establishes a baseline for future reclamation of the site. The permit application <br />includes the following: <br />• Permitted acreage of 49.98 acres of which approximately 3 is surface disturbance at the mine portal area and <br />approximately 3 acres is proposed exploration drilling activities. <br />• An Environmental Protection Plan as required by Rule 6.4.20. The plan has a radiometric survey of exisiting <br />conditions, geo-chemical analysis of waste and uranium ore rock, and an established monitor well program. <br />The plan notes: <br />a) Existing radiometric conditions note the area has a historical mining history so reclamation will be <br />returned to exisiting average levels or better. <br />b) Ore and base materials in the ore storage area will be placed back in the mine upon reclamation. <br />Materials will be removed until readings are back to established baseline radiometric readings or <br />bed rock is reached. <br />c) Reclamation will include topsoil and vegetative cover to prevent or retard precipitation infiltration. <br />d) The monitor well, which is dry, will continue to be checked quarterly. Nuvemco will submit reports <br />quarterly within 10 working days of sampling. If the dry trend continues, DRMS staff will review an <br />operator request to change the sampling frequency through a technical revision submission. <br />e) An engineered stormwater control plan to hold a 10 year / 6 hour event and pass a 100 year / 24 <br />hour precipitation event. <br />• No ore shall remain on site for longer than 180 days. If the mine goes into a temporary shutdown must be <br />removed prior to the shutdown date. <br />• The mine is noted as having intermittent status <br />Office of Office of <br />Mined Land Reclamation Denver • Grand Junction Durango Active and Inactive Mines
