  11. Slide 11: Mining Strategy: Triple Lift Stoping in Wide SWB Zones

    Gwalia Mining Strategy Triple Lift Stoping in Wide SWB Zones Mining method • Long hole open stoping with fill • North & south access on two levels gives 4 mining areas DL3 • Greater percentage of free 2 bogging increases productivity DL2 of each stope 40m 1 DL1 DL3 • Sill drives fully in ore – reduc

    Gwalia Mining Strategy (cont.) Double Lift Stoping in South Gwalia Series and Narrower SWB Zones 80m // // 15m Cable Bolts and straps 40m 25m Cable Bolts and straps Mining method • Cable bolts installed from central ore drive, reducing dilution • Production drilling parallel to hangingwall to reduce

    Gwalia Mining Strategy (cont.) Single Lift Stoping in Narrower Zones (Main Lode, West Lode) 87m // // 20m 40m 20m Mining method • Lower hydraulic radius reduces dilution • Production drilling parallel to hangingwall to reduce blast induced dilution 12 / Gwalia Site Visit Presentation | August 2019

  14. Slide 14: Mining Strategy (cont.): Island Pillar Method Opportunity

    Gwalia Mining Strategy (cont.) Island Pillar Method Opportunity 30m Mining method 15m • Island pillar supports hangingwall, reducing dilution 25m • Allows strike length to be increased • Fixed part of stoping cycle effectively spread over two stopes • Potential increase in stoping productivity 13 /

  15. Slide 15: Mining Strategy (cont.)

    Gwalia Mining Strategy (cont.) Objective: Maximise production, constrained by: 1) Waiting for adjacent/above stope’s paste fill to dry Plunge, centre 2) Geotech considerations – not too many open stopes of lode too close together = ‘Centre out’ method ‘Centre out’ – extract centre stope of lode firs

  16. Slide 16: Stope Cycles targeting higher production

    Stope Cycles targeting higher production Stope Cycle Time – 6 months per stope • ‘Bogging’ (extracting ore from the stope) represents just under 50% of stope cycle time • Filling and curing around 30% of stope cycle time • PAF circuit optimisation to aid in reduction of filling time • Adjacent stope

  17. Slide 17: Extension Project Update – On Schedule

    Gwalia Extension Project Update – On Schedule • Gwalia Extension Project (GEP) consists of two main components: a ventilation upgrade and paste aggregate fill (PAF)1 • Budget of A$112 million with planned completion in Q2 December FY202 • A$100 million spent on project to date • PAF crushing circuit
