The International Mineral Valuation Committee (IMVAL) has released the third edition of its standards for minerals, including oil and gas. IMVAL's history goes back to discussions in Brisbane in April 2012 to harmonize the mineral valuation codes, such as VALMIN (Oceania), SAMVAL (South Africa), and CIMVal (Canada). It also looked to include, where appropriate, International Valuation Standards (IVS) and the U.S. Uniform Standards of Professional Appraisal Practice (USPAP), as they contain valuation standards of general application to mineral property valuation.
