EXCEPTIONAL METALLURGICAL RESULTS DELIVERED AT TRÊS ESTADOS

Highlights:

• Results received from extraction tests at Três Estados indicate that exceptional levels of precious metals can be recovered by relatively simple refining techniques

• Results are from hydrometallurgical extraction test work undertaken on a 5kg bulk surface sample at e-Recicla Ltda precious metals refinery

• The combined assay results received were 102.18g/t Au (3.28oz/t), 63.32g/t Pt (2.04 oz/t), 36.72g/t Pd (1.18oz/t) and 135.20g/t Ag (4.35oz/t) from a two-stage extraction process which produced two precious metal buttons

• Pyrometallurgical test undertaken on two 15kg samples at the Marcelo da Silva Pinto M.E. precious metal refinery, São Gonçalo, greater Rio de Janeiro delivered assay results of 666g/t (21.41 ozs/t) Ag and 466g/t (14.98 ozs/t) Ag

• The same homogenised sample used for both hydrometallurgical and pyrometallurgical tests, from the same general location as TER 048 announced on 27 February 2017

• Importantly, both processes used in the test work can be simply adapted for commercial extraction
