There is no evidence to suggest that there is any mechanism in the Resolution process circuit likely to result in technologically enhanced naturally occurring radioactive material (TENORM) in tailings, concentrate, or process water.

Data presented in this technical memorandum indicate that asbestos abundance in Resolution ore and development rock falls well below this criterion. Based on analysis of asbestos occurrence in Resolution ore it is likely that asbestos abundances in the tailings will also be low.

The primary objective of the testing presented in this report was to further enhance and expand the Project’s understanding of the potential geochemical reactivity of the scavenger tailings, although some process waters and pyrite tailings from the 2014 pilot plant were also tested.
