The Preliminary Economic Assessment (PEA) is a scoping-level study which relies on information from disciplines such as geotechnical, environmental, infrastructure, and markets in addition to the core inputs from mining, geology, and metallurgy. Capital and operating cost estimates for the project will typically be estimated to ±30%.
Our engineers and geologists have many years experience in the completion of PEA's and will typically develop cost estimates to the required accuracy by obtaining vendor budget quotations in addition to using data factored from recent projects and/or operational assignments.
