Operational Strategies • OOOOO Process Improvement Streamline Processes • Cost Reduction Cost Efficiency Initiatives - Maintenance Delta Dunia Digital Maintenance • • Digitizing our manual maintenance procedures (WICOPE) Streamlining maintenance process while producing more accurate and higher quality results Further improving control over the maintenance process and providing more efficient inventory management. Predictive Maintenance and EHMS Improved condition-based monitoring of equipment health, allowing for more effective and longer component life extension Utilizing artificial intelligence to better and more accurately predict the needs for maintenance and devise most effective maintenance plans, therefore streamlining maintenance process, reducing manhours, and reducing cost. Addressing Mineplan Issues Direct Dumping • Soft material issues at one of the largest site has created productivity challenges Previous dumping method requires blending of soft material with hard material to prevent dangerous area throughout site. Lack of blending material delays production process Direct dumping uses channeling method whereby soft materials or mud can be channeled directly to specific disposal area that will not impact operations Managing Unpredictable Weather Various planning scenarios for multiple rain hours assumptions ensuring better planning and preparation against unpredicted weather Optimize time loss during rain by using for other activities such as maintenance to reduce down time during high-production period. Post-recovery management: ensuring the sufficient availability of equipment necessary to reduce slippery hours such as graders and pumps for optimized use. Managing fleet post rain to ensure lowest incremental cost ― STRICTLY CONFIDENTIAL - 29
