Learning and Discussion of Innovative ideas about Mining Waste Management and also Mining Related News and Activities
Mine Waste Management Short training sponsored by Government of Japan through JICA in corporation with the Government of PNG through CEPA, MRA and DMPGM.
Landowner grievances is always a challenge for the PNG Mining Industry. However, the Regulators of the Mining Inductry facilitate Mining Warden Hearings and Development Forums to address grievances related to mining.

Mechanize Small Scale Mining
Artisanal and small scale
gold mining (ASSM) offers lucrative employment opportunities to the locals of
most developing countries. The major drawback of ASSM is its impacts on the
environment as a result of improper mining and processing techniques. Exposed
and disturbed lands are usually subject to soil erosion and avalanches of
debris in active ASSM areas. Mercury is commonly used to concentrate gold, and
if not handled properly causes pollution of life supporting river systems.
Small
scale gold miners in many developing countries rely primarily on deposits
containing free gold and may be classified as shallow/deep alluvial or lode
type. The mining method used in artisan small scale gold mining employ very
basic technology. Shallow alluvial deposits are commonly found in valleys and
streams at depths not more than two meters. Deep alluvial deposits are found
along major riverbanks and older river courses, and usually at depths exceeding
six metres along the banks of rivers. The lode type of gold deposits is usually
composed of partially weathered gold bearing reefs, which are either outcrops
or near surface deposits. In Papua New Guinea, active artisanal mining are
commonly found abandoned mining areas like Panguna and Missima and also near
operating mines like Porgera, Eddie Creek in Wau Bulolo, Morobe Province. Not
only that but also other parts of the Provinces also have active small scale
miners. Other provinces include but not limited to: East Sepik, Sandaun, Enga,
Western, Eastern Highlands, Jiwaka, Madang, Western Highlands, Oro, Milne
Bay,Morobe.
