F'A~~E J.i • • !2.~ The ability to use any ore which meets certain guidelines is inviting a situation where there will be a supply which exceeds ,~^~~\~ the milling or reclamation capacity. ,.~ti~, i ~;~~.,,, Oversupply will likely lead to ore from other locations ~ ~~ being stored in unstable heaps surrounding the mill site. A ,;~ reasonable limitation would be that no more than one days feed ;~ for the mill be allowed to be stored onsite. In addition, any ,~,~' ore stored should be on a covered pad with controlled drainage, ~,,~~'``- so there is no runoff into the environment. ~~_ Already, there is a problem onsite from unstable historic tailings piles upon which there has been uncontrolled drainage. Adding more heaps will increase potentially dangerous drainage problems. In addition, if a limitation is placed on the mill feed storage, this will tend to avoid unnecessary ground disturbance at the source area for the ore. The increase in the number and size of storage piles will lead to additional reclamation which requires a permit amendment 'l /not technical revision. ~."i 3~ If offsite material is permitted, to regulate the supply, the operators should be 'ven a timetable for supplying information on the source supply before the Division pproves or denies its use. The Division should require that ore samples from any supply be tested on a level equal to the ore that was the basis for the guidelines and then be given one week to review the results before determining if the ore is suitable for the mill. Only after that period may the ore be delivered to the mill. The ore should be sampled by as independent testing lab who draws their nwn samples on the ground. ;~ ' 4.i To prevent any unauthorized ore from reaching the mill, all ~a should be logged in at the mill by the truck drivers stating where they picked up the ore from and such records should be supplied to the Division on a monthly basis or sooner upon request. 5. Any soiree of are must come from permitted land. For instance, COM pas not requested a permit for the Bueno Mine/Mill which ie proposed to be a source and prompted this application. AS a condition before approval of offsite ore as a feed for the mill they must apply for and obtain a permit for the source area. 6. MLRD cannot permit a mill which relies exclusively on offsite supplies. This is the job of CDH. what assurance does the Division have that when milling from off-site materials, onsite materials will also be processed. Is the operator simply trying to bootstrap itself into becoming a custom mill by owning some
