The transfer of skills and knowledge of alluvial gold mining took place in the 1950s and 1960s when many residents, especially around the Wau/Bulolo area, applied for and were granted MLs. By the early 1970s, most expatriates who originally held mining leases for small-scale gold mining in the country had transferred their leases to citizens.

Artisanal and Small-Scale Gold Mining (ASGM) is a low-cost yet highly destructive mining practice, leading to environmental disasters across the world's tropical watersheds. The topic of ASGM spans multiple domains of research and information, including natural and social systems, and knowledge is often atomized across a diversity of media and documents. We …
THE RESULTS. The AquaCycle TM water management system recovers up to 90% of the water used throughout the process, as a result, on average, the CDE and AuVert approach uses 77% less water than traditional methods without using any toxic chemicals. This ensures the water supply won't end up contaminated and unsafe for the neighboring community. The AquaCycle …
Alluvial is a term that refers to soil sediments and the various sand, silt, gravel, clay or other deposited matter left behind by flowing water. "Alluvial gold" refers to the type of gold dust found in that kind of soil. When the beds of rivers or streams are scooped and panned for gold dust, the product is referred to as alluvial gold.. Panning for gold is one of the oldest …
