Financial Modeling of Mining Projects: A Tool for Optimizing the Financial Benefits of the Mining Sector. The financial model of a project is one of the most important documents a mining company will submit as part of a package of documents to get a mining license in most mineral-rich countries. However, this valuable tool seems to be underused ...
The small scale artisan miners in many developing countries employ very basic tools and equipment to conduct mining operations. In PNG, small operations consist of less capital intensive manual excavations of alluvial gold deposits found in streams/rivers, puddles and ancient river terraces. Panning dish, pick and shovel are the main tools used.

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 …

Shaft Mining. When alluvial gold became scarce, miners turned to shaft mining. Shaft mining is a technique used by miners where miners would use picks and shovels to dig shafts or tunnels underground. These shafts were 1 metre squared and were up to fifty metres deep. Miners used propped wood up against the walls and roof of the shaft/tunnel to ...

Alluvial diamond mining in the region dates back to at least 1904 (Marshall, 1986, 1987a). More than two million carats of diamonds were recovered up to 1984 by artisanal miners washing the alluvial gravels of this field. The alluvial diamonds found in the region have not been linked to any known primary source rocks.
