Mineral Exploration an overview ScienceDirect Topics
02/10/2011 Mineral exploration can be technically defined as “all the activities and evaluation necessary before an intelligent decision can be made establishing size, initial flow sheet, and annual output of new extractive operation.” The purpose of mineral exploration is the discovery and acquisition of new mineral deposit amenable to economic extractive operations now or in future.

Methods of mineral exploration: Geology onhym
Methods of mineral exploration: Geology. Geological mapping is an essential tool for mining exploration work. It is carried out at different scales according to progress in exploration and generates geological maps that show the lithology of the outcrops and the structures with mineralization and mining potential.

Prospectivity analysis is a GIS–based predictive spatial analysis technique used to integrate multiple exploration datasets in the framework of a mineral deposit model. The output of the process is a map displaying favourability for the occurrence of a particular mineral deposit type. This powerful tool for the identification and ranking of exploration targets has been applied to studies of prospectivity for

Surface and Subsurface Methods of Mineral Exploration
Geochemical methods involve the measurement of the chemistry of the rock, soil, stream sediments or plants to determine abnormal chemical patterns, which may point to areas of mineralisation. When a mineral deposit forms, the concentration of the ore "metals" and a number of other elements in the surrounding rocks is usually higher than normal. These patterns are known as primary chemical halos.

Methods and stages of Mineral Exploration: Adaptive
20/06/2016 Methods for Mineral exploration may include: Remote Sensing: Usage of sensors for collecting data about an object or area without being in direct contact with it. These sensors can be on satellites or mounted on aircraft. Geologic mapping, aerial photographs, satellite imagery and airborne geophysical data are some examples of this category.

Methods of mineral exploration: Geochemistry
BLEG (Bulk Leach Extractable Gold): is a geochemical exploration method for regional or detail exploration for precious metals especially gold. It has been tested and applied successfully in different geological and climatic settings. It is used to detect the fine gold in the clay and silt fraction of streams. The BLEG has very good reproducibility in results and a very low detection limit.

Drilling Techniques for Mining Exploration Equipment
13/12/2018 Generally, mineral exploration involves percussion and rotary drilling to produce rock chips and samples of core. Drilling is used to obtain detailed information about rock types, mineral content, rock fabric, and the relationship between the rock layers close to the surface and at depth. It is used in areas that have been selected as “targets” based on geological, geophysical, and/or geochemical methods.

Exploration geophysics Wikipedia
Exploration geophysics is an applied branch of geophysics and economic geology, which uses physical methods, such as seismic, gravitational, magnetic, electrical and electromagnetic at the surface of the Earth to measure the physical properties of the subsurface, along with the anomalies in those properties. It is most often used to detect or infer the presence and position of economically useful geological

Mineral Exploration, how it's done
Mineral exploration is the process of searching for evidence of any mineralisation hosted in the surrounding rocks. The general principle works by extracting pieces of geological information from several places, and extrapolating this over the larger area to develop a geological picture. Exploration works in stages of increasing sophistication, with cheap, cruder methods implemented at the start, and if the

Methods for valuating early-stage mineral projects CSA
The Appraised Value Method is based on the premise that the real value of an Exploration asset lies in its potential for the existence and discovery of an economic mineral deposit. The Appraised Value Method assumes that the amount of exploration expenditure is related to its value. Therefore, it is important to understand the definition of capital expenditure in mining industry (see Figure 3).
