Idaho Copper uses ore sorting, reducing costs. PEA and PFS updates for US market financing. Strong copper demand for the green economy. In 2020 SRK completed a PEA for Idaho Copper (formerly known as CuMo). At the time the Engineering Consulting firm valued the project at $1.7bn with an estimated payback period of 7 years. Idaho Copper is now gearing up for a revised PEA and Pre-feasibility Study that takes into account the Company’s potential to use ore-sorting which will make its project even more economically robust. Ore sorting is a common technique used in mining to sort the waste from the ore prior to processing. It generally results in lower capital and operating costs, often significantly improving project economics. Although Idaho Copper’s project is referred to as a copper porphyry, it is really a thin-vein system, referred to by miners as a stock-work system, and therefore the deposit lends itself to ore sorting. In a thin-vein system, the metals are dispersed in a regular fashion throughout the rock in a network of veins, which is clearly visible in the core samples. These veins are extremely thin and contain up to 90% of all the metals in the deposits. This makes it much easier for the mining team to separate the waste from the ore.
