Mapping and Assessment of the Economic Impact of Small-Scale Surface Mining of Alluvial Gold Concentration in Talensi Nabdam District, Ghana
Mapping and analysis of alluvial gold concentrations as well as assessment of the impact of mining activities on the people of Talensi-Nabdam District, Ghana was undertaken. The mining concessions allocated to small-scale miners were surveyed and mapped using Total Station and Electrometric distance measurement equipment. Forty concessions were investigated: the largest covered 28.3ha. Analysis of ore bodies and slope percentage shows that Manganiferous Rock has the highest percentage rate of occupancy (46.5 %) with a slope percentage rate of 0-90%. Sandstone follows with 26.8% rate of occupancy and a slope rate of 0-100%. Sandstone and Quartz field-Spar Porphyry have the highest slope rate within 0-100%. Predictive terrain analysis indicated that the concentrations of the deposits are geographically located within the North-East and South East regions of the study area. Gold production evaluation shows that maximum increament was experieced in the year 2001 with a production unit of 85,596 (Oz). Employment criteria evaluation of socio-economic impact revealed that the number of individuals engaged in the gold mining activity increases annually: from7.3% of the population in 2004 to 20.5% in 2010.
