Before the contract is signed, RS data are collected and given a primary analysis: Terra / Aster, Landsat / ETM+, Hyperspectral, Hyperscan, SWIR, etc. The survey is planned: the best geometry is calculated after a full informational geological analysis of the territory taking the available RS archive into account. Materials are collected for a vector topographic map of the search area at 1:10 000 – 1:50 000.

Indicator-mineral schemes are prepared at 1:50 000, 1:25 000 and 1:10 000. The vector topographic map of the search area is 1:10 000 – 1:50 000. The space-structural scheme shows linear and basic focal structures and areas of anomalous tone change.

Frequently asked questions
Answers to key questions about service parameters, timelines, deliverable formats and workflow. If you did not find what you need — contact us and we will help.
Direct identification of, for example, ore-bearing gold by remote sensing is unlikely because there is little of it in the rock, so the contribution of "light" from gold particles will be suppressed by the "light" of the rock. Therefore, only indirect identification of ore-bearing rocks by the "color" of the rock or other known criteria of gold content of the environment is possible.
Gold exploration is the process of studying the geological features and composition of the earth in search of gold. This process involves various methods and techniques that help to determine the presence of gold in the ground and its potential quantity.
One of the main exploration methods is geophysical and geochemical surveying. Geophysical methods include gravimetric, magnetic, electrical, and radiometric methods that examine various physical properties of the earth and determine changes in those properties that may indicate the presence of gold. Geochemical methods include the examination of soil and rock samples and the examination of groundwater for gold and other elements.
Other exploration techniques may include drill holes, geologic mapping and the study of the geologic history of the area being explored.
Once the data has been collected and analyzed, an estimate of the gold resources in the deposit is made. This includes estimating gold volumes and concentrations, as well as determining the economic viability of gold mining in the deposit.
It is important to note that exploration for gold deposits is a complex and expensive process that can take many years to complete and not all deposits prove to be economically viable for mining.
Gold-bearing rocks are rocks that contain gold as minerals or microscopic particles. Gold can occur in various rock types, but the most common are the following:
-
Quartzites are a rock type consisting predominantly of quartz. Quartzites may contain gold, which is usually found in quartz crystals or in sulphide layers.
-
Shales are thin beds of clays, limestone and other minerals. Shales may contain gold of microscopic size, usually not visible to the naked eye.
-
Carbonate rocks are rocks consisting of carbonate minerals such as calcite and dolomite. Carbonate rocks may contain gold, which is usually found in voids and fractures of the rock.
-
Rocks containing sulphides are rocks consisting of sulphides such as pyrite, chalcopyrite and others. Sulphide rocks may contain gold that is associated with sulphides or occurs in voids and fractures of the rock.
-
Rocks containing oxidised ores are rocks that contain gold in the form of oxidised minerals such as iron oxides and hydroxides.
It is important to note that gold can occur in rocks at various concentrations, and not all rocks contain economically viable amounts of gold.
Gold assaying is the process of determining the purity of gold and its quality. This process can be accomplished by a variety of methods, depending on the purpose for which the gold will be used.
One of the main methods of gold assaying is chemical analysis. Chemical analysis can be used to determine the gold content of alloys or rocks, as well as to determine the quality of gold products.
Another gold sampling method is to evaluate the appearance and weight of gold pieces. This method can be used to determine the quality and purity of gold based on appearance and weight, but it does not provide an accurate analysis of gold content.
There are also other methods of gold assaying such as hardness testing, magnetic testing, density measurement and melting point determination.
Gold assaying is an important process to ensure the quality and purity of gold, especially if the gold will be used for jewelry production or investment purposes.
The estimation of inferred gold resources is the process of determining the quantity and quality of gold in potential deposits that have not yet been mined. The estimation of inferred gold resources involves the use of geological data, geochemical and geophysical studies, reserve modeling and other techniques to determine the presence and quantities of gold in a particular area.
The estimation of inferred gold resources is usually performed in the early stages of exploration of geological targets and can be used to make decisions about further investment in gold exploration and production. It helps to determine the likelihood of finding gold in new areas and to estimate its potential economic value.
The estimation of inferred gold resources typically involves the evaluation of various parameters such as geologic structure and sediment properties, deposit type, mineralogical characteristics, geochemical and geophysical data, and the extent to which they are consistent with known gold deposits. The estimation of inferred gold resources determines the amount and grade of gold that can be mined taking into account economic and technical factors.
