Alluvial gold was mined during the colony, before 1960, by 4 colonial companies. At that time, most of the prospectors was involved in alluvial and veins of quartz and ignored the dissiminated gold. The most attractive deposits in the region are disseminations. They occur in chemically responsive rocks : typically carbonates and pyritic or graphitic facies. Gold reacts in BIFs (Banded Iron Formation) in a combination of chemical barrier (iron oxides) and the high tectonic competence of the rocks. These mining permits cover the same geological environment as the well known gold deposits in eastern of DRC. This unexplored gold deposit should interest mining companies at a time where gold is being discovered at a fraction of the rate needed to replenish reserves. Models and Exploration Methods for Major Gold Deposit Types There has been significant progress in the last decade in the understanding of the geology, settings and controls of the diverse types of gold deposits, including the recognition of new deposit types in new environments. Such progress has been paralleled with the development of data integration, processing and visualization techniques, and of advances in geophysical, geochemical and spectral detection techniques. Geologists are now better equipped than ever to face the increasingly difficult challenge of finding gold. However, one of the key lessons of the last decade, as reminded by Sillitoe and Thompson (2006), is that the exploration work needs to remain grounded in geology, especially in the field, and the elaborate detection techniques and tools available will only find their full power when closely integrated with a good geological framework. Mining cooperative project to assist artisanal miners This project is part of the World Bank's policy of leading the Mining Sector Support Project, called PROMINES (cf http://www.prominesrdc.cd/ ) On the report on Improving Artisanal Gold Mining in the DRC published on http://www.prominesrdc.cd/fr/Rapport/PROMINES KEVIN TELMER final.pdf, we read: "It is estimated that about 80% of DRC's gold comes from informal operations of artisanal gold mining, although the actual production figure is unknown. If an official figure of industrial gold production of 10 tonnes is used, the implication would be that the artisanal sector produces 80% more, thus 50 tons of gold." We believe that artisanal production is much more important.. Congolese legislation has created very favourable conditions for bringing artisan diggers together in cooperatives. It is still necessary to motivate the diggers to join these cooperatives which allows to leave the informal domain and join the formal domain that benefits the development of the country. The only way to do this is to provide the cooperative with the right techniques for exploitation and recovery as well as the right equipment to drastically increase productivity per digger. First, alluvials or evaders must be prospected by wells to establish the depth of the unsealed gravel and the height of the mineralized gravel. The non-mineralized cover must be moved to an already exploited area while mineralized gravel must be transported to a concentration station where water is available. Here is a rational operation with a hydraulic shovel with long arms. A second, smaller shovel must load the trucks that bring the mineralized gravel. Productivity will then be an impressive factor compared to the exploitation shown on this picture : The strategy is then to unite the diggers in a cooperative that will establish a cooperation agreement with Mbomo-Mountains sarl in order to create a win-win association. Mbomo-Mining sarl finances the equipment and trains the diggers, and markets the production and takes its fair remuneration. This strategy is in line with the World Bank's wishes to ban mercury pollution widely used by diggers for amalgamation concentration. Once the gold is amalgamated, mercury is often evaporated without any protective measures or recovery. The interest for Banalia Mining sarl is to create the best harmony with the population in order to promote the development the mining permits. The recruitment of personnel to carry out geochemical prospecting and prospecting by drilling will be done mainly among these artisan miners who will receive the appropriate training.
