A mineral resource is a concentration of solid material of economic interest in or on the Earth's crust with reasonable prospects for eventual economic extraction. Mineral resource models are commonly generated using specialised software applications, based mostly on information from exploration programmes and mine production. Updating of mineral r...
Article

Resource estimation is commonly performed in separate domains that are defined using different criteria depending on the type and geometry of the deposit, the mining method used, and the estimation method applied. The validity of estimation domains can be critical to the quality of produced resource estimates as they control various steps of the es...
