Feasibility Study and Technical Report - Pretivm

26.0 RECOMENDATIONS26.1 GEOLOGYThe author makes the following recommendations:• Complete mining and processing of a 10,000 t representative bulk sample fromVOK.• Continue infill drilling of the Inferred Resources along strike at VOK with the aimto upgrade the classification of the estimates to Indicated Resources.• Continue to attempt to define high grade resources and their geological controlsin the zones outside of VOK and West Zones.• Continue to refine the geological model with the aim of improving the singleintegrated geological model.The budgeted cost for the drilling and associated studies (including the resourceupdates) is $20 million, whilst the cost of the underground bulk sample is budgeted at$30 million. These costs are in Canadian dollars.26.2 MINERAL PROCESSING AND METALLURGICAL TESTINGAlthough the test works indicate good metallurgical response to gravity and flotationconcentration, a significant variation in metallurgical performance was observed. TetraTech recommends further metallurgical test work to confirm the findings. Pilot plantcampaigns on a large size of samples should be conducted. The recommended test workincludes:• Additional metallurgical test work and mineralogical evaluations should beconducted to confirm the metallurgical response of the samples to theestablished process flowsheet, including locked cycle tests. The samples usedfor testing should include the samples representing the initial five years millfeeds based on the updated mine plan. The cost of the test work is estimated tobe $200,000.• Pilot plant campaigns to better understand the metallurgical performances. Thecost of the test work is estimated to be $500,000.Further cyanide leach tests should be conducted to improve gold and silver metallurgicalperformances if cyanidation is considered.Pretium Resources Inc. 26-1 1291990200-REP-R0012-02Feasibility Study and Technical Report on the BrucejackProject, Stewart, BC
