卢旺达拥有许多矿产品，对目前全世界的高科技产业具有重大经济利益。特别是钽铌、钨和锡的开采过去和现在仍然很重要。该国的地质图是可用的，但这些都是区域比例（1：100.000比例），因此不能直接用于重点勘探和采矿规划。因此，进行了以勘探和开采为重点的更详细的地质测绘。建立了矿点的区域分带模式，可作为找矿矢量。岩性和构造对矿化的控制已被认识，并已确定了几种矿物，可用作矿石勘探的探路者。我们认为，卢旺达矿藏的存在和规模有利于初级采矿公司进行小规模工业开采。
Rwanda contains many mineral commodities that are of major economic interest for the current high-tech industry worldwide. Especially the mining of tantalumniobium, tungsten and tin were and are still important. Geological maps of the country are available, however, these are at a regional scale (1:100.000 scale) and as such not straightforward to use for focused exploration and mine planning. Therefore, a more detailed geological mapping focusing on exploration and exploitation has been carried out. Regional zonation patterns of the mineral occurrences have been established which could be used as exploration vectors. A lithological and structural control on the mineralization has been recognized and several minerals have been identified that could be used as pathfinders for ore exploration. In our opinion, the occurrence and scale of the Rwandan deposits favour small-scale industrial exploitation by junior mining companies.
