Investor Presentaiton
Project Optimisation
Significant additional value targeted via test-work and flowsheet update
Opportunities due to Plant
Integration
Brief Description
Deliverables
1
Project Synergy Review
(underway)
2
Recirculate Float Tails
(underway)
3
Integration of FH gold CIL Plant and Capital and operating cost savings
Hayes Creek flotation
Leach float tails though CIL circuit
to improve overall Au + Ag
recoveries
Timing
Total additional recovery of
metals (AuEq*) over Life of
Mine (LoM)
Update integrated process flowsheet
& est. capex requirement to
implement changes
Jan '23
n/a
Leach tests on float tails to quantify
Au + Ag recoveries & reagent
consumptions
Feb '23
Target up to 15-20koz
Equipment requirements & +/- 35%
capital estimate
Review existing test work &
marketing/ offtake terms, identify
opportunities, recommend test work
H1'23
Target up to 35-40koz
Improve distribution and
recovery of payable metals
Alternative processing of
Precious Metals (PM)
concentrate stream
Refinery limits on concentrate
grade & deleterious elements results
in lower float recoveries, nil
payment for certain metals, e.g.,
copper & lead
Assess alternative process to PM
flotation circuit to improve resource
utilisation/recoveries/ tailings
Options analysis for on-site treatment
and refining of PMs
5
Updated Integrated Plant
design to PFS level confidence
and accuracy
Incorporate the above findings in
an updated PFS
Test-work to determine optimum
processing route and PM recovery
for onsite treatment
Cost benefit analysis
H1'23
Target up to 30-35koz
Prepare PFS on Integrated Plant, and
improved utilisation and payables of
HC ore
H2'23
Target total 80-95koz over
LoM

(AuEq) Gold Equivalent - incorporates other payable metals such as silver and zinc in addition to the contained gold and converts into a gold equivalent value, refer PNX PFS 17 June 2021 for further details
