Permit M-1982-020, Permit Amendment <br /> Exhibit T- Environmental Protection Plan (EPP),Amended <br /> Chemicals and Materials to be used on the permitted area <br /> We are evaluating several different reagents to be used in the mill for the upcoming <br /> extractive metallurgical process. The following is a list of reagents,not currently <br /> included in the existing EPP,that may be used onsite when testing indicates which ones <br /> yield optimal results. This new list is intended to replace the existing set of xanthate <br /> reagents. <br /> Cytec XR(Xanthate Replacement) Series reagents: <br /> Aero 3473 <br /> Aero 3739 <br /> Aero MX 5160 <br /> Danafloat 271 Mineral collector <br /> Danafloat 468 Mineral collector <br /> Danafloat 577 Mineral collector <br /> The reagents shown above are not xanthates. One of the changes in this amendment is <br /> eliminating the use of xanthates in milling processes. The reagents shown above are <br /> not classified as "designated chemicals." In fact,they are very benign and are <br /> recommended by Hazen Research,which are reasons they are being considered for use <br /> in processing our ores. Please see the supplementary pages,further describing the <br /> properties and data of each material. <br /> The reagents are all in liquid form. They will be stored inside the mill facility in the <br /> designated location,in their original labelled containers, and kept from freezing. Given <br /> the average rate of importing and processing the ores, estimated to be 100 tons per <br /> day, and the small amounts required of these reagents, only a limited amount of each <br /> material will be stored onsite. Materials being stored will not exceed the containment <br /> capacity of the storage facilities. See updated map for reagent storage location in the <br /> mill building. <br /> The list of other materials included in the original EPP, such as fuel,lubes, <br /> hydrocarbons, pH adjusters, etc., does not change. All necessary and appropriate spill <br /> containment and clean-up materials will be maintained on the site. Onsite personnel <br /> will be fully trained in the storage,handling and containment of these materials. See <br /> updated map for locations of fuel storage and imported ore storage. <br /> Groundwater Monitorine <br /> The existing EPP includes a groundwater monitoring plan,which will continue to be <br /> followed. There is no change to the sampling frequency,sampling locations, or the <br /> parameters analysed. All monitoring and analyses will be reported as required. <br /> (cont.) <br />
