o Fed into process stream at the flotation cells via a metered feeder, 10-20% solution concentration at 0.05 - 0.2 lbs/ton of "ore". Pine Oil Frother, upto (1) 55 gal. drum, liquid - for flotation chemistry. o Creates a stable, robust froth that has selective properties for sulfide minerals. o Stored in Flotation Trailer. o Fed into process stream at the flotation cells via a metered feeder, undiluted solution concentration at 0.03 - 0.2 lbs/ton of "ore". Ball mill solution volume is approx. 15 cu. ft. of +/- 60% pulp density. Flotation cell solution capacities are as follows (+/- 30% pulp density) • 1't Stage, (2) cell unit with total capacity of approx. 74.7 cu. ft. • 2nd Stage, (4) cell unit with total capacity of approx. 33.6 cu. ft. • Yd Stage, (6) cell unit with total capacity of approx. 128 cu. ft. As a part of normal mill operations, mill process water will be continuously monitored. A pH monitor and data recorder will be installed at the tailings pump location within the mill. Should the pH reach a state outside of the 7.5-9 range that is necessary to precipitate the heavy metals, alarm notification will be activated for the operations personnel. Recorded data is saved in 30 day increments available for future audit The submittal notes on this Serfilco Model 432 monitor/recorder can be found attached in this Exhibit C. If the pH falls outside of the 7.5-9 range, the operators are instructed to shut down the operation that delivers waste to the impoundment. Once the source of the problem is corrected upstream in the process, waste can then be continued to be discharged to the impoundment. It is practically impossible for heavy metals to be in solution under these operating conditions (pH range of 7.5-9) as shown in the attached A Water Handbook for Metal Mining Operations, by Thomas R. Wildeman. Storage of lubricants, oils, and greases may be as follows (see Best Management Practices within the SWMP attached in the appendix of this Exhibit C): • Any 55 gal. drums may be stored outside, on wooden pallets to prevent rusting of steel bottoms. Drum openings shall be protected from rain with appropriate caps/plugs or a hand pump device installed. • Any 5 gal. plastic buckets may be stored outside. Spouts shall have appropriate caps in place when not in use. • Any quart containers, cartridges, or blocks shall be stored inside trailers. In the event of spills of any of the above liquid chemicals (excluding water), absorbent cloths shall be used to collect the liquids. Cloths containing flammable liquids shall be placed in an approved receptacle for such disposal, located in the Ball Mill Trailer. Cloths containing non-flammable liquids can be disposed of in municipal waste receptacles. Special disposal and handling methods of any particular material shall conform to those enumerated in the specific Material Safety Data Sheet. A current collection of these documents shall be located next to the First Aid kit located in the Ball Mill Trailer. There are NO designated chemicals used in this proposed mining operation, therefore no special emergency response plan is necessary. In the event that there is a spill of feedstock (waste rock and/or ore), the operators are instructed to STOP the activity and assess the situation. Once the source and cause of the spill have been determined, a plan shall be devised to prevent any further spillage. After the source has been stopped, the spill may be cleaned up. Cleanup shall include using machinery (loader, excavator, etc.) or manual tools (shovel, buckets, etc.) to scoop up the material and return it to an appropriate place. An appropriate place is either the original point source, Crusher Feed Pile or whichever conveyor or feeder mechanism the material has spilled from originally. This will place the spilled material back into the regulated process stream. Page 12 of 37
