Valuation Standards and Codes

Mineral property valuations are governed by six primary international codes: IMVAL (International), CIMVAL (Canada), VALMIN (Australia), SME Valuation Standards (United States), SAMVAL (South Africa), and the RICS Red Book (United Kingdom). Each code requires that valuations be prepared by a Qualified Person or Competent Person with relevant education, experience, and professional certification.

Indicators of Fraud in Mineral Valuation

The five most common indicators of fraud in mineral property valuations are: (1) unrealistic resource estimates that significantly exceed comparable deposits, (2) absence of a Qualified Person or Competent Person sign-off as required by IMVAL and NI 43-101, (3) missing or fabricated drill hole data and assay certificates, (4) valuations that materially exceed recent comparable transactions without justification, and (5) failure to disclose material environmental liabilities, permitting risks, or encumbrances.

Last updated: . Compiled by Thomas Brachey, PMP.

Lack of Independence

The evaluator has a direct financial interest in the property or the commissioning company, compromising their objectivity.

Unjustified Assumptions

The use of overly optimistic commodity price forecasts, unrealistic metallurgical recovery rates, or underestimated capital and operating costs without robust justification.

Non-Compliance with Standards

Failure to adhere to recognized reporting codes (e.g., NI 43-101, JORC, SME Valuation Standards) or the absence of a sign-off by a verified Qualified/Competent Person.

Data Manipulation

Selective reporting of drill hole data (e.g., highlighting only high-grade intercepts while ignoring barren zones) or inappropriate statistical treatment of outlier grades.

Opaque Methodologies

The valuation relies on proprietary or undisclosed methodologies rather than accepted industry approaches (Income, Market, or Cost approaches).
