The TH663i truck is designed for intelligent mine operations and improved productivity. It also comes automation- ready and can be equipped with an optional AutoMine Trucking Onboard package. The automation compatibility provides the possibility to move equipment operators from underground to other locations, improving safety. Q: What Sandvik systems will aid the mine? TZ: My Sandvik is a web-based customer portal that provides 24/7 customer support no matter where you are in the world. It lets you keep track of your fleet’s performance, plan for preventive services, and make your decisions based on accurate data. Not only does it provide you with access to information on your fleet, you can also use it to request quotations and place orders at any time. Sandvik’s AutoMine product family spans a range of both surface and underground mining applications. The continuously evolving portfolio covers all aspects of automation from tele-remote or autonomous operation of single pieces of equipment to multi-machine control and full fleet automation with automatic mission and traffic control capability. In the comfort and safety of a control room, operators can simultaneously control and monitor the movements of a fleet of driverless loaders or trucks deep below the surface, or drill rigs on the surface. Sandvik solutions provide a safe and controlled environment for operators and maintenance personnel both on the surface and underground. Sandvik’s OptiMine is a modular information management solution that offers a real-time view of your underground mining operations. Suitable for all mining applications and the entire mobile fleet, including equipment supplied by other OEMs, the solution is designed to provide real-time tracking and production management tools for controlling both manual and automatic mining operations. Sandvik OptiMine modules can be combined as needed to build up the required functionality and to optimize your

mining operations. With open interfaces, the solution can also be integrated to other mine IT systems. For example, Resolute is using OptiMine Smart Scheduling which works with Deswick and other data to support decision making. TZ: Resolute is using the OptiMine: 1. 3D Mine Visualizer: Based on the 3D scanning results, Sandvik OptiMine 3D Mine Visualizer brings a three- dimensional model of your mine layout directly to your office. This significantly enhances comprehension of large mining environments. One of the key benefits of 3D mine visualisation is how it enables users to more effectively communicate and interpret data around the current situation and future plans for the mining environment. Situational awareness is improved, as information about the mine can easily be studied and understood at a glance. 3D mine visualization is a valuable tool in operations planning, analysing problematic areas and tracking mine development over time. 2. Drill Plan Visualizer: Sandvik OptiMine Drill Plan Visualizer is an easy to use visualisation tool for production and rock support drilling. Drill plans and drilling results are visualized in a user- friendly and informative way, giving you the tools you need to compare drilling results to production drilling and bolting plans. Drilling plans and bolting scenarios can be easily created, modified and edited for the most optimal results. Drill plans are transferred to the drill automatically and actual, real-time drilling data is immediately available in the production control system. Q: Which technologies is Resolute Mining using? Q: What is unique about Resolute’s Syama mine? A: The Syama underground mine will become the world’s first purpose-built, fully automated sublevel cave gold mine in the world. b

Q: Why did Resolute Mining decide to partner with Sandvik Mining and Rock Technology? TZ: Resolute Mining identified several benefits of working with Sandvik Mining and Rock Technology on automating its Syama mine. These include increased machine productivity and performance; a reduced number of machines required; reduced risk and better safety outcomes; a reduction in underground personnel; lower production costs per tonne; greater control of mining with less variation; a reduction in wear and damage; increased productivity and efficiency; greater machine life; the potential for mining rate increases; and the ability to train the workforce using new technologies. John Welborn, Resolute MD and CEO, believes Sandvik is the only equipment provider that could offer the full suite of proven autonomous equipment and digital solutions that the gold miner required. Q: What cost reductions do you expect following full automation? TZ: Resolute’s Syama automation plan, along with a power upgrade project, has helped it reduce the cost profile of the operation by as much as 15%. An updated definitive feasibility study (DFS) released in July 2018 lowered Syama’s all-in sustaining costs (AISC) from US$881/oz to US$746/oz. The lower cost profile is supported in the new DFS by a 38% increase in underground reserves and a four-year increase to the mine life to 2032. Q: What Sandvik solutions will be used? TZ: Sandvik’s i-series range of equipment supports the movement of mining companies into an underground automation environment. Within the range, the LH621 loader has been matched with the TH663i truck due to their designed payload capacities. The LH621 features the latest Sandvik Intelligent Control System and My Sandvik Digital Services Knowledge Box on-board hardware for product health monitoring and faster trouble shooting.
