The jar <br /> tests will be performed in March during low-flow conditions and a sample will be <br /> collected from the Mine portal. A representative high flow sample will be made in the <br /> field during that same time in March and it will be prepared based on historical changes <br /> in water quality during high flow conditions. The reasons for creating a representative <br /> high flow sample are that the testing needs to be conducted early in the pilot testing to <br /> support the adjustments to the pilot-scale testing approach and the overall testing will <br /> need to be completed prior to high flow conditions will likely occur at the Mine. A <br /> summary of the items being tested is shown in Table 9. <br /> Treatability Study Work Plan 15 February 8,2018 <br />
