Corporate Presentation July 2020
Buckreef Resources More than Doubled
- M&I gold resources for the Buckreef Shear Zone more than doubled compared to the previous estimate
- Incorporates the results of the 2019 Phase I and II drill program (52 holes, 17,650 m)
- ‒ Phase I: 15-hole infill drilling of the PFS open pit to convert inferred to M&I resources
- ‒ Phase II: 37-hole expansion drilling extended shear zone by >200 m along strike and to 950 m depth
- Low discovery cost of only US$6/oz Au
Oxide Ores At Or Near Surface
- Contain less than 2% of the gold in the PFS open pit. More suitable to be treated by a separate smaller plant.
- Initial focus is to mine and stockpile up to 1 million tonnes from the proposed oxide pit
- Oxide pit extends over a 37,000 m2 area
- 0.5 to 1.0 m of overburden above oxide pit
- Existing stockpiles of 120K tonnes at 1.86 g/t Au containing 7,161 oz Au
- Plant at ~5 tph of set to expand to treat ~15 tph (300 tpd)
- Flow sheet to include conventional gravity and cyanide leaching CIL with cyclones and centrifuges
- Previous metallurgical testing indicates high recoveries
