PEA RVPP announced before Feb 1 2021 (definition incl) :) Before a mineral resource project becomes a mine, several technical studies must be completed on a deposit to ensure its economic viability. As mentioned, putting a PEA together is one of the first steps in the process, with prefeasibility and feasibility studies following.
All of these studies analyze and assess the same geological, engineering and economic factors; however, they include significantly different levels of detail and precision. For example, unlike a prefeasibility or feasibility study, PEAs may contain results of metallurgical testing that are based on an inferred mineral resource. That means the mineral resource estimate that they include may be based on limited information and sampling of the mineralization.
PEAs must either be presented in the form of a technical report, or supported by a technical report. In some cases, the technical report must be independent. PEAs are sometimes called scoping studies.
