valleys in several alluvial gold districts. With the recent increase in the gold price over the past several years, the amount of smallscale gold mining, primarily of alluvial deposits, has increased dramatically throughout Ghana and especially in places like the Atewa Range, where substantial alluvial gold resources are known.
