Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.

Borehole Mining (BHM) is a remote operated method of extraction (mining) of mineral resources through boreholes based on in-situ conversion of ores into a mobile form (slurry) by means of high pressure water jetting (hydraulicking). This process is carried-out from a land surface, open pit floor, underground mine or floating vessel through pre ...
Ore fluids debouched onto the seafloor and pooled in a second-order sub-basin's depocentre, precipitating a stratiform massive sulfide layer from 3 to 8 m thick, with exhalative chert, manganese and probable K-bearing hydrothermal clays. The central area of the exhalitive massive sulfides lying above the feeder zone became progressively ...
Antimony: stibnite, Xikuangshan Mine in Hunan; Arsenic: arsenic, realgar, orpiment, and arsenopyrite. Minerals with the formula MAsS and MAs 2 (M = Fe, Ni, Co) are the dominant commercial sources of arsenic; Lead: lead is usually found in ore with zinc, silver and (most abundantly) copper, and is extracted together with these metals.
The Rovina mine was also opposed by environmental and environmental justice groups. [4] That project was stalled in 2021. [5] Anti-mining organisations have attempted to ban gold cyanidation in Romania, because this process has resulted in environmental disasters, such as the 1971 Certej dam failure and the Baia Mare cyanide spill in 2000.
