Artisanal and Small-scale mining (ASM) are important part of Nigerian Mining Sector which has the potential to raise internal revenue in addition to foreign exchange, create employment and reduce poverty and encourage foreign direct investment (FDI) if is well managed. ASM in Nigeria is undeveloped and has been long neglected due to over dependence on oil. Over 90% of mining activities in Nigeria are ASM of which 75% are carried out illegally. The sector is unguided and unregulated.The policies in place are inadequate and the miners are untrained. This makes ASM to adopt poor quality operational techniques that causes environmental disaster and losses of substantial revenue to the country through exports as well as royalties and taxes. A lot of topics and sub-topics that will make students self-employed will be covered in this course.Some of the topics include the principle guiding the operation of ASM, mining and processing some selected minerals for the benefit of mankind, market opportunities for the minerals, challenges of ASM in Nigeria and so on
This course is a visionary tool designed to draw studentsâ€™ attend to the relationships between scientific and technological knowledge, national policy and policy implementation and the eventual development of a nation as measured by its production capacity, resource management and improved living standards.
ïƒ˜ This course is an introductory and practical course to the study of mine surveying. It is designed primarily for mining engineering students to replicate surveying operations both on surface and in underground mines.
