Technology & Innovation Development at Lihir Remote mining, lower energy intensity, step change refractory processes Breakthrough challenge: • Reduce all-in Kapit hot mining costs . Step reduce energy intensity of refractory processing Convert large mineral endowments to higher margin production levels Value capture levers Robotic mining . Remote safe hot mining to reduce pit cooling costs NextGen hydromet . Further processing energy intensity savings by step reduction of selective oxidation • Alternative refractory processing for step change cost reduction and convert low margin mineral endowments Sustainable mines . • Retain and expand geothermal power K Recovery of Gold Remote mining equipment Quickly recover high gold bearing, reactive pyrites Broadened Op Range Leave more low gold bearing, less reactvie blocky pyrites Fondslidesulphur % Oxidation & Energy Intensity Refractory energy intensity reduction TRL 2 3 4 5 6 7 8 Principles & Needs Concept Application Proof of Concept Analysis Formulation Experiments Component Bench Testing Component Prototype Testing System Scale Testing System Field Trial Demo Build, Commission & Optimise = TRL Technology Readiness Levels.
