Many mineral resources have exhibited logistic Hubbert-type production trends in the past, but have transitioned to exponential growth during the last 1015 years, precluding reliable estimates of reserves from within the framework of the logistic model.Published July 1st 2017 by Routledge USGS Home Contact USGS Search USGS (2009) indicate that the debate about how to analytically describe resource depletion is ongoingor its licensors or contributorsWhile most mineral resources will not be exhausted in the near future, global extraction and production is becoming more challenging. Miners have found ways over time to extract deeper and lower grade ores with lower production costs
