Amidst the general fall in metal prices over the last few years, the gold price has remained comparatively stable in the US1,000-1,250o range. Gold bulls were disappointed that the price did not break through the 2,000o ceiling nevertheless the current stable price run has helped to maintain a strong interest in gold projects.

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their interest for gold is the most valuable tool for exploring new deposits.

Gold is a very widely disseminated throughout nature and may be found in any geological formation from the oldest rocks to the deposits that are still being formed, but in common with other metals, it is more likely to be found in the oldest rocks and in those places where the earth crust has undergone the most extensive changes such as elevations, folding, tilting, faults, fissuring and also volcanic action, with resulting changes in the composition and texture of the rocks.

In general, photogeology involves the interpretation of an areas geology from analysis of landforms, drainage and vegetation. Basically, there are four types of information, fracture and trace analysis, fracture identification, seep detection and channel change study. When a fracture is observed in cross section, it seems to be vertical or near vertical breaks in the bedrock. Gold particles can be deposited into fractures. Other important information is the called lithological mapping, which involves the interpretation of surface features so that can be obtained a more exact map.

Photographic surveys follow specified flight routes and take the photographs at regular spacing along the path. The overlap between adjoining photos in a sequence along the line is about 55-60. The overlapped area is detected by the camera from two different views in two different photos. The two adjoining photos used together make what are called a stereo pair. The two photos can be placed side by side and observed with a stereoscope.

Surface seismic techniques used in gold exploration are restricted to seismic refraction and seismic reflection methods. Probably, the first one is the most employed. The equipment employed for both techniques is very similar and assure the travel time of acoustic waves propagating through the subsurface. In the seismic refraction method, the travel time of waves refracted along an acoustic interface is measured. In the other technique, the travel time of a wave which reflects off an interface is measured.

Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer mining often occurs within a streambed, it is an environmentally-destructive type of mining, releasing large quantities of sediment that can impact surface water for several miles downstream.

It is essential in the evaluation of a gold deposit to have, as accurately as possible, a model of the mineralied one geometry, shape, sie, quality, variability, and limits. Physical, chemical and geological characteristics may vary greatly within a single deposit and from deposit to deposit. Critical data can be collected in a variety of ways, including drilling, surface andor underground mapping, geophysical or geochemical surveys, or studies of rock mechanics properties, mineralogical types and relations.

Other points to be sampled are stream sediment. These samples have to be collected in different stations along each drainage and theirs positions can be determined by using a GPS. Results of the survey provide information on potential areas of anomalous base and precious metal values throughout the place. By performing statistical analysis is possible to know what one or ones are more important and basically the gold and silver distribution.
