The Data that started the strategy

InLine Pressure Jig

Key Technology

Vertical Shaft Impactor (VSI)

• Feed accelerated, leaves rotor at 70 m/s.

• Rock on rock crushing – breaks along grainboundaries

• Handle large variation in moisture content,ideally suited wet screened products

• Can handle range of feed sizes

Inline Pressure Jig (IPJ)

• Adjustable screen for different crush sizes20mm down to 200µm

• Adjustable ragging size and SG for targetedrecovery

• Variable mass yields• Gold and sulphide recovery tool

Why Jigs?

IPJ - Benefits

IPJ

•Low opex•Easily optimised•Highly secure•Sharper cut-points•Fine mineral recovery•High availability•Simple Water balance•Adjustable mass yields

Intelligent Unique Technology

• InLine Pressure Jig• InLine Leach Reactor• Gekko Python• Gekko Mag-Screen• InLine Spinner• G-Rex Resin Column• Gekko Carbon Scout• Gekko Electrowinning

Modular engineered system

Gold Fields – Agnew Gold Mine WA

Gekko Systems designed, manufactured, installed andcommissioned a turnkey gravity box package in 2011,taking gravity recovery from nominal levels of 30% tolevels in excess of 60%

•Up front test work and modellingcapability (Gekko signatories to AMIRAP420 Gravity Modelling)

•Feed rate and equipment sizing's –Modelled / Optimised

•Fully engineered solution

•Throughput flexibility

•Screening, concentrator options

•Packaged electrowinning circuit options

Gravity Box - Features

Gold Fields – Granny Smith Gold Mine

Gekko Systems designed, manufactured, & installed a turnkeygravity box package in 2015, successfully commissioned,exceeding GRG modelling expectations

Online Gold Analyser (OLGA)

CSIRO Developed Technology & Equipment

• Utilises newly developed XRF technique thatprovides a step change in performance to allowthe direct measurement of Au

• Lab testing conducted by CSIRO, initial unitsready for plant trials

• “Real time” measurement of gold in slurry- feed, concentrate, tailings

Paper #9378: Yves Van HaarlemUltraGold: Real-Time Gold-in-Slurry Analysis with 100 ppb AccuracyTuesday August 29th at 10:30Georgia B - 2nd Floor

OLGA Technology

Au reading every 10 min. (averaged over 1hr)

• Au slurry sampled continuously

• X-ray irradiation of slurry in launder tank

• Irradiated material emits characteristic X-rays

• Software analysis provides Au concentrationPatent related to dual focusing of X-ray beam

Software determines Au

Tails ** 0.2 – 0.7 120

Notes* Indicative** Based on laboratory feasibility study (plantsamples)*** Improvement expected

OLGA - Application

• Measure stream continuously– Excursions detected and rectifications made sooner– Reduced periods out of target range– Rapid feedback on optimisation changes to process

• Specific opportunities will vary from site to site

• Target applications could be:– Tails stream to increase gold yield– Reduction of pourable gold reporting to copper concentrate– Optimising unit processes– Other…….
