43-101 Feasibility & QP Reporting
Roughstock conducts both SK1300 and 43-101 Feasibility Studies and QP Reporting.
SK1300 report is the SEC standard for mineral resource companies in the USA to accurately report information about their mineral prospects and mining properties. RMS has people qualified and experienced to produce these reports.
National Instrument (NI) 43-101 is the standard for mineral resource companies to accurately report information about their mining properties. Core requirements for 43-101 are designed to protect investors and ensure quality of the mineral resources and the ability to economically mine these resources. All aspects of the report must be approved by the qualified person. QP’s must be an qualified engineer or geoscientist with at least five years of experience in mineral exploration and a professional designation.
Mineral resources and mineral reserves are the two primary concepts of a 43-101 Feasibility study. There are three different types of mineral resource classifications: Inferred Mineral Resource, Indicated Mineral Resource and Measured Mineral Resource; and two different types of mineral reserve classifications: Probable Mineral Reserve and Proven Mineral Reserve.
