Geostatistical and Machine-learning Methodologies for Predicting Recoverable Mineral Value in U.S. Critical-mineral Deposits: A Critical Narrative Review
Critical minerals underpin energy, defence, digital and advanced-manufacturing systems, yet the economic value of a deposit depends not only on in situ grade but also on how much mineral value can be recovered under variable geological, mineralogical and operating conditions. In the United States, prediction is particu...
