Pre-feasibility Study The pre-feasibility study (PFS) is an intermediate step in the engineering process to evaluate the technical and economic viability of a mining project. The pre-feasibility study is a critical step for project development as it represents the minimum prerequisite for conversion of a geologic resource into a reportable reserve.
Sep 13, 2021 Highlights of project optimizations to be incorporated in the upcoming feasibility study (the Feasibility Study or FS) include Open pit mining the majority of the Main deposit, allowing the Company to capitalize on the high-grade, near-surface mineralization, resulting in lower operating costs than underground mining.
Jul 22, 2021 Sandvik Mining and Rock Solutions will supply a battery electric haul truck and loader to evaluate performance and suitability for future underground mining fleets. Pre-feasibility studies are also being progressed to extend open pit mining at Kennecott beyond 2032, with a further push back of the North Wall to allow access to Mineral Resources.
The study was divided into two phases first, a technical feasibility study of applicable mining methods, and second, an economic feasibility study, based on the designs developed in the first phase. The first phase, completed in July, 1975, recommended four mining methods for the phase II study. The four methods are chamber and pillar mining ...
