Exploration operations result in defining the geometry (dimensions), location, and quality (grade) of the deposit, which forms the basis for mine design. The economic calculations and the choice of extraction method are based on the ratio of waste to ore, which determines whether mining will be economically viable and whether it will be done via open-pit or underground methods. Open-pit mining, which is the approach Emidco adopts, involves removing the waste material above the ore body, with stepped (bench) mining being the most common method. This method’s design principles aim to achieve the least amount of waste removal for the maximum ore tonnage. Key components of open-pit mining include pit design, access roads (ramps), waste dump placement, and selecting the best transport methods for waste and ore. Using exploration data and the mineral’s genesis, the mine pit is designed and simulated to outline and implement the most optimal path to the ore. Before extraction begins, necessary equipment is installed and set up based on the mining method, waste removal rate, and ore reserves.
