be sent to the laboratory for analysis. Geological characteristics of the sample are then recorded inside the field note book and the database ready at the planning phase. Those characteristics are used further for interpretations. In the course of this work, two types of samples were taken i.e. stream sediment and rock sample:

• For stream sediments, five kilograms of the sample is required (**Figure 11A** and **B**). Although when the sample is wet, the weight can go up to seven. Apart of the coordinates, characteristics of the sample which have geological significance are recorded apart; those are color, composition, contamination (**Table 1**). Every sample receive a unique identity called ID like QTXXX (with QT = initial of Tanni Quinter; XXX = sample number planned).

• For rocks, a fresh part of the rock which can permit to make good geological observations like grain size matrix, color, alteration mineral is picked (**Figure 12A** and **B**). The sample here must also help to build tin section in case of interesting features inside like alterations minerals as sulfurs. Every sample receives a unique ID like RQTXXX (with R = initial for rock; QT = initial of Quinter Tanni; XXXX = sample successive rock number) **Table 2**.

The database is filled during this phase though a form set. **Figure 13** shows a form set we built as an example. A form set is a user interface of the database. Its importance is to avoid bad manipulation. The interface is built by the Database management team. The geologist is the user. The information primarily *DOI: http://dx.doi.org/10.5772/intechopen.106632 GIS and Database Management for Mining Exploration*

recorded inside his notebook should be filled. The result is an integral database (**Figure 13**).

### *6.2.1 Tracking*

During navigation, the geologist stores the road used inside his GPS through tracking (**Figure 14**). Tracking is recorded automatically. They show at which distance the
