By the middle of the 10th century, the discovery of ancient gold workings in different parts of the country had led Arab geographers to speculate on Ophir in their writings (Summers, 1969). The Portuguese occupied parts of the country in the 17th century and traded in gold with local miners. Profile: Dr. Tendai Njila holds a BSc.

Historical Development of small scale mining in Ghana The word ―Galamsey‖, as small scale mining is popularly known in local parlance, was derived from the English phrase ‗gather them and sell' (Mohammed, 2013 ). Another example is the giant copper-gold-uranium deposit at Olympic Dam, South Australia, discovered beneath 300 m of cover using an exploration program based on models developed by Western Mining Corporation geologists for Zambian copper belt-type deposits.

A few gold deposits are hosted in shear zones that are oblique to the regional deformation and cut across different lithologies. A rational geological classification of the commonly recognized lode gold deposits is feasible if it is based on the geological settings of the deposits, host rocks, nature of mineralization and geoche m-ical signature.

Zimbabwe on a World Wall Map: Zimbabwe is one of nearly 200 countries illustrated on our Blue Ocean Laminated Map of the World. Although emerald deposits are relatively rare, they can be formed in several different, but specific geologic settings and the classification systems and models currently used to describe emerald precipitation and predict its occurrence are too restrictive, leading to confusion as to the exact mode of formation for some emerald deposits.
