(TSXV: DBG) (OTCQB: DBLVF) (FSE: 1D4) (\"Doubleview\") is pleased to provide additional information regarding the metallurgical process and significance of achieving 56% scandium (\"Sc\") recovery to a scandium phosphate precipitate, in the first attempt of sequential purification of HAT deposit flotation tailings. The HAT Copper-Gold-Scandium-Cobalt deposit is located in the Golden Triangle region of the Atlin Mining District in British Columbia.Initial independent laboratory tests completed by Coffey, Tetra Tech were designed to demonstrate the validity of the underlying process chemistry. Achieving 56% Sc recovery shows that primarily, the response to the treatment program was predictable and as anticipated.Expectations are that scandium recoveries in the range of 80% to 90% will ultimately be achievable with further process development and optimisation. Production of a phosphate lends itself to the solution purification scheme currently under test. Once recovered, scandium can be converted to other forms. Alternative treatment strategies are also being considered.EUR ING Andrew Carter B.Sc. CEng. MIMMM, MSAIMM SME of Coffey, Tetra Tech noted \"Even at moderate recoveries, the HAT deposit has the potential to meet international demand for scandium for the foreseeable future. As scandium is a by-product of a waste stream, recovery is not the fundamental driver, cost is. If it can be demonstrated that scandium can be recovered at an acceptable cost, then scandium has the potential to add significant value to the HAT deposit. A techno-economic evaluation for the production of scandium as a by-product of HAT copper-gold production will be evaluated on conclusion of the test work phase.\"Mr. Carter also noted that \"Reported recovery rates for other projects, either in planning or under development, are 76.2% at the Flemington Project on the low end, and 88.0% at the Syerston Project on the upper end. This positions the potential for Doubleview's HAT deposit favourably as it is targeting an 80-90% recovery rate, however it is noted that other scandium projects currently under consideration are treating later...
