What is mineral exploration ?


ProspectionThe exploration usually starts by looking for interesting exploration zones and by the sampling in geological areas that seem to have an interesting mineral potential.

searches are conducted in order to discover base metals and precious metals. The areas of interest are staked by the exploration company whether by an interactive map or by agreements with prospectors in the area. Before starting work on the ground, it is essential to make an application for a permit to the government agencies in order to comply with regulations.
Moreover, according to the location of the studied area on public or private land, permits and agreements are required to ensure compliance with surrounding communities.

Mineral exploration includes :

  • the prospecting,
  • the detailed mapping,
  • the digging of trenches,
  • the stripping,
  • the grooving,
  • And the different geophysical and geochemical surveys.

The different geophysical surveys are collected, or over ground, or in surface and will allow to obtain anomalies caused by minerals in the rock. Then, survey teams will go characterize on the field, anomalies and additional surveys will be launched on the surface to reduce the search area. Samples will be taken directly into the rock or in soil (till, sediment) of the anomalous sector in order to perform analyzes to find the presence of economic metals


The discovery of a mineralized showing occurs when we concretely find a value item. It is at this phase that we decide to perform more advanced exploration work whether for detailed geophysical surveys or for digging of trenches. Sampling is more systematic than exploration and the objective is to identify continuity and consistency in analysis values.;


Advanced exploration

DecapageAt this phase, we can now call a mineralized deposit. The exploration in surface is becoming increasingly significant and it is at this level that we have to thoroughly test, the discovered deposit with the help of drill. Wood cutting works begin whether for the building of new roads, the stripping of the mineralized zones or the preparation of drilling sites. So, the drilling of trenching turns into stripping on the prime sectors where we must remove all the part of the top (soil and organic matter). Following this work, the teams adequately clean the rock in order to take systematic samples using the grooving saw and to perform a geological detailed mapping.


All these elements will set the stage at the last step to determine the economic potential of the bed to take the step of a deposit: the drillings. This step is the most expensive of all, and it will decide if the company goes ahead or if that it is not worthwhile to invest money in the project. This decision will lead to the sale of the property to another company or simply ignore the mineral claims previously staked

Planning and resource exploitation


Finally, it is at this step that permits, leases and licenses are needed and that the project can be submitted to an environmental assessment with public authorities. A small quantity of mineral deposits discovered becomes exploited mines in the world. The prefeasibility and feasibility studies on the future exploitation can take up to 10-15 years for the mine to develop. Rarely the projects reach this course of development.
