SURVEY PROCESS

STUDY STAGES

Mineral deposits are rocks that have been formed as a result of geological processes and contain extraordinary elements. They can be grouped as Metallic Minerals, Industrial Raw Materials and Energy Raw Materials.

The characteristics of the country rock should be taken into account in the planning of mineral exploration. Magmatism, surface alteration or weathering, sedimentation, metamorphism can cause mineralization. Parameters such as whether the formation is simultaneous with the host rock, the type and shape of the formed bed, the relevant elements and alterations, and the age of formation affect the exploration program and therefore the costs according to the mineral to be searched.

The exploration of any mineral requires the analysis of the geological events that took place in that region, the areas where they are effective, the rock types and geometry. The exploration process begins with the interpretation of previously generated data, continues during the mine’s production, and continues for some time even though the mine is consumed. According to the formation characteristic of the mineral sought,

1. First of all; Basic regional data such as paleogeography, geology, remote sensing, geochemistry, geophysics, metallogeny maps and mineral/occurrence information are evaluated by office work.

2. Field studies are started in the form of preliminary searches (prospecting) in important regions (provens). Geological, geochemical and geophysical maps (small scale) are completed and stratigraphic drilling is done when necessary.

3. As a result of the evaluation of the data collected from the preliminary search areas, the detailed searches (exploration) phase is started in the determined target areas. Mining geology, geochemistry anomaly, geophysical maps (large scale) are completed. Exploration (reconnaissance) and reserve drillings are made. When necessary, methods such as splitting/gallery are applied and a technological test sample is taken.

If the reserve, grade, paragenesis, mineralogical properties and technological test are positive, a feasibility report is written, which also evaluates other parameters necessary for the production of the mine. The mine is ready for operation.

4. In the light of updated mine geology maps and other information, it is investigated whether there is a continuation of the mine or another mine formed in connection with the problems encountered in the production process and after the production is completed in the vicinity or deeper.
