SRK Consulting (UK) Limited (SRK) is an associate company of the international group holding company, SRK Consulting (Global). SRK provides a comprehensive range of consulting services to the resource industry. Consulting services are for mineral resource projects ranging from exploration, development and exploitation through to closure, and in the fields of geology, mining, infrastructure, bio...
Purpose is to substantiate foundations of sustainable management mineral resources while implementing a circular economy model. Methods. The study has applied following research approaches: synthetic method (unification the singled out aspects); induction (analysis features); life cycle assessment (evaluation product influence on environment from viewpoint each stage its cycle); toolkit (determ...
Mineral resource estimation involves the determination of grade and tonnage a mineral deposit based on its geological characteristics using various methods. Conventional methods, such as geometric geostatistical techniques, remain most widely used methods for estimation. However, recent advances in computer algorithms have allowed researchers to explore potential machine learning techniques Thi...
Genetic Algorithm Calibration of Probabilistic Cellular Automata for Modeling Mining Permit Activity
We use a genetic algorithm to calibrate a spatially and temporally resolved cellular automata to model mining activity on public land in Idaho and western Montana. The genetic algorithm searches through a space of transition rule parameters of a two dimensional cellular automata model to find rule parameters that fit observed mining activity data. Previous work by one of the authors in calibrat...
Measurements that describe and summarize quantitative predictions relating to the classification of geological variables and samples derived from geochemical and geophysical data sets are important because of the large amount of information contained in such data. Methods considered in mineral resource quantitative prediction include quantification theory, which is able to deal with data includ...
Intensified mineral consumption and reserve depletion means that it is becoming increasingly important for policymakers to account for and manage national mineral capital. Exergy replacement costs (ERC), an indicator based on the second law of thermodynamics, provides a physical value of mineral loss. When only a unit mass analysis is used, the role of scarcer minerals, such as gold, is obscure...
A com mon el e ment in plan ning the ad min is tra tion of the land sur face—or base—is to col lect in for ma tion that sum ma rizes cur rent and po ten tial uses of an area un der con sid er ation for a change of use. This in for ma tion should en com pass all mea sures of value of the land, such as cul tural, eco nomic, en vi ron men tal or wild life. Brit ish Co lum bia has a well-es tab lis...
The Hubbert-type analysis used to analyze the production history of oil is applied here to other raw materials. Many resources commonly thought of as being close to "peaking" such as lithium, helium, copper, and the rare earth elements, show no evidence of logistic behavior at any point in their production histories. Although many resources have exhibited logistic behavior in the past, many now...
