1. FUNDAMENTALS FOR A SUCCESSFUL COLLISION AVOIDANCE SYSTEM ACCURACY In all relevant operational scenarios ! RELIABILITY In all environmental conditions ! SIMPLICITY Easy to Use, Install & Maintain ! ! COUPLE WITH THE RIGHT PRIORITISATION: 1. People 2. Equipment 3. Infrastructure

2. COMMITTED TO PROVEN, ACCURATE & RELIABLE COLLISION AVOIDANCE Mining represents some of the most challenging environments for operators and equipment to work in. ! Open Pit operations utilises oversized equipment operating across great and complex areas. ! Underground mines plunge to great depths in narrow and elaborate tunnel systems. Both types of mining represents extreme conditions that affect the safety of operators as well as the equipment performance. ! The process of safely managing people and machine interaction 24/7/365 days a year adds immense complexity to equipment, environment, logistics and costs management; but most of all adds significant risk to the miners most valuable assets; its people. ! Implementation of ACCURATE & RELIABLE Collision Avoidance that DO NOT RELY on 3rd party technology such as GPS, RFID or WIFI; a fundamental step towards SAFER MINING.

3. ANY COLLISION AVOIDANCE SHOULD ASPIRE TOWARDS Intelligent technology choice; Highly configurable, Scalable & Future proofed. Ensure People protection Be Simple to use and maintain Ability to remove false positive alerts today and in the future. Do not rely on 3rd party infrastructure (GPS,GNSS, Wi-Fi etc) Centralised Management, Local and Remote Data Logging Critical Situational Awareness (contextual) UG and Above ground capabilities Interface to Machines and other site systems ! While meeting the above, the CAS must be Cost Effective, Robust and Reliable in order to increase safety in mining while supporting production processes. !
