At the OSC’s request, the Revised Report provides (1) additional information in Section 19.1.3 on the growth forecast for global scandium markets provided by an independent scandium market expert (OnG Commodities LLC and Dr. Andrew Matheson) and relied upon by the Company in its August 2017 Feasibility Study;  (2) an analysis in Section 22.4 showing Net Present Value and Internal Rate of Return sensitivities of the Project at +/- 30% of the August 2017 Feasibility Study’s assumed product pricing, capital expenditures, and operating costs;  (3) disclosure in Section 3 of the reliance on OnG Commodities LLC and Dr. Matheson; (4) the removal in Section 24 of certain disclosure regarding the Company’s relationship with Dr. Matheson; and (5) inclusion in Section 25 of certain risk factors.
