IFRS 6 — Exploration for and Evaluation of Mineral Resources
IFRS 6 has the effect of allowing entities adopting the standard for the first time to use accounting policies for exploration and evaluation assets that were applied before adopting IFRSs It also modifies impairment testing of exploration and evaluation assets by introducing different impairment indicators and allowing the carrying amount to be tested at an aggregate level (not greater than .
Mineral Extraction - an overview | ScienceDirect Topics
Mineral extraction sites, which include strip mines, quarries, and underground mines, contribute to surface and groundwater pollution, erosion, and sedimentation The mining process involves the excavation of large amounts of waste rock to remove the desired mineral ore The ore is then crushed into finely ground tailings for chemical .
