**8. Conclusion**

At the end of this investigation which consisted of highlighting the importance of GIS and database in early stage of mining exploration, the objectives assigned, that were to build a reliable database and a GIS to ensure the planning phase is optimized and the results of this work meets standard operations procedures. The database built is capable to record and store geological and non-geographical information without being compromised by the mis-manipulation of geologists while at the same time it helps to ensure distances between sampled points and the planned ones do not exceed a certain distance.

The GIS is able to gather maps and geographical data for planning the field work and assessing results. Tools developed can then be used by any mining exploration project or company to work wisely and respect norms inside the mining sector. GIS and database are used in both Greenfield exploration projects to establish mining blocks based on statistics and in the brownfield exploration projects to do analysis using statistical methods like variograms to understand the behavior of our deposit. These analyses create grade control which guides in exploitation giving ideas of areas of high grade and low grade hence a suitable beneficiation method to be employed. The Meiganga area permitted us to effectuate the deployment and testing of our tools. However, some limitations have been highlighted concerning GIS. This shows that GIS and Database will always need to be in conformity with field work.
