Placer Mining

High Quality Content by WIKIPEDIA articles! Placer mining is the mining of alluvial deposits for minerals. This may be done by open-pit (also called open-cast mining) or by various forms of tunneling into ancient riverbeds. Excavation may be accomplished using water pressure (hydraulic mining), surface excavating equipment or tunneling equipment. The name derives from Spanish, placer, meaning "sandbank." It refers to mining the precious metal deposits (particularly gold and gemstones) found in alluvial deposits?deposits of sand and gravel in modern or ancient stream beds. The metal or gemstones, having been moved by stream flow from an original source such as a vein, is typically only a minuscule portion of the total deposit. The containing material may be too loose to safely mine by tunneling. Where water under pressure is available, it may be used to mine, move, and separate the precious material from the deposit.

Semi-Mechanized Small-Scale Fluvial Placer Mining
38,00 € *
ggf. zzgl. Versand

Mining is a profitable business, not only for large global players, but also for small-scale operators, who exploit alluvial deposits in a semi-mechanized manner. However, literature is virtually non-existent when it comes to the investment assessment of such small-scale projects, which is why this book has been written. First, an introduction to the mining business is given and alluvial deposits are explained. Secondly, the entire placer mining process and its inputs and outputs are qualitatively analysed by means of an economic value chain analysis. In a third step, a real-life business case example is examined quantitatively, in order to evaluate the economics of alluvial mining projects. Furthermore, core economic drivers and their impact on financial Net Present Value are identified by use of a self-built dynamic calculation model. In a final step, the mining endeavour is embedded into a particular geographic context to measure the economic effects of a specific environment.

Yentna-Cache Creek Mining District
40,10 € *
ggf. zzgl. Versand

High Quality Content by WIKIPEDIA articles! Gold was discovered in the Yentna Cache-Creek Mining District in the US state of Alaska (also known separately as the Yentna District or Cache Creek District) of the upper Susitna Valley in 1898, soon followed by claim staking. Placer mining was reported in the Cache Creek drainage of the Dutch Hills by 1906. Quaternary glaciofluvial deposits, alluvial deposits, and Tertiary conglomeratic white quartz-breccia units have been mined in the Dutch Hills. About 200,000 ounces (6.2 tonnes) of gold has been produced from these placer deposits. By 1927, a road from Talkeetna was constructed into the mining area, known today as The Petersville Road. The abandoned mining camp of Petersville, Alaska served as the area Post Office for several years in the late 1920s and early 1930s. Two areas have been set aside for recreational gold mining, the North and South units of the Petersville State Recreation Mining Areas. Many smaller one-man and family placer mining operations continue today.
