JD-8 Mine Environmental Protection Plan <br /> • massive, darker colored mineral(Nininger, 1954). When oxidized,these minerals may become much <br /> brighter in color and reveal secondary minerals such as corvusite,ravite,and pascoite(Peters,2011). <br /> These oxidation minerals are often seen in conjunction with uraninite within the Uravan Mineral District. <br /> The primary vanadium mineral is montroseite(VOOH)in conjunction with vanadium clays and <br /> hydromica. Carnotite and tyuyamunite are also commonly seen vanadium minerals after oxidation of the <br /> ore occurs. It is possible that other oxidized vanadium minerals occur on the JD-8 mine site.The presence <br /> of other cations, increased moisture levels,and differing pH levels may enable other vanadium oxides to <br /> form over time(Peters,2011). <br /> Ore will be temporarily stored onsite for no longer than 180 days for offsite transport to a processing <br /> facility.The ore storage pad is located on the waste rock pile(Figure 2)and occupies less than 0.25 acres. <br /> The amount of ore stored on the ore storage pad at any given time will not exceed 4,000 tons. Currently, <br /> because the mine is on intermittent status,all stockpiled ore is stored inside the mine and will be moved <br /> to the external ore storage area after the mine resumes active status. In the event of a mine shut down the <br /> ore will not be left on the surface for more than 30 days. <br /> Waste rock is placed on the waste rock piles as described in the mine plan. Waste rock is also gobbed <br /> underground into mined out stopes,to reduce the volume of the external waste rock pile.The current <br /> waste rock pile contains approximately 36,000 tons of material.According to the expected mine plan, <br /> approximately 184,000 tons will be added to the waste rock pile for a total of approximately 220,000 <br /> tons. These estimates may change if future exploration drilling locates additional resources.At the end of <br /> • mining,the waste rock piles will be reclaimed as described in the Reclamation Plan included as Exhibit E <br /> of the JD-8 Mine Permit. <br /> • <br /> 14 <br />
