[Extract] The Philippines is one of the most richly endowed parts of the Southwest Pacific, with many porphyry copper-gold and epithermal gold-silver deposits scattered along the archipelago (e.g., Sillitoe and Gappe, 1984; Mitchell and Leach, 1991; Fig. 1). Chinese mining artifacts discovered in the Baguio and Masbate districts suggest that gold and silver mining dates back to at least the ...

MAPS SHOWING METALLIC MINERAL DISTRICTS AND MINES IN THE BLACK HILLS, SOUTH DAKOTA AND WYOMING By Anna B. Wilson and Ed DeWitt INTRODUCTION The Black Hills of South Dakota and Wyoming contain a wealth of mineral deposits that range in age from Early Proterozoic or Late Archean to Quaternary and in type from iron-formation to placer.
gold miners Small-scale miners Some SSM communities continue to practice the same method of gold extraction developed by their forefathers, whereas other groups are innovative and try to improve working techniques to increase gold recovery rates. An excellent example of this is a group of SSM in the Benguet province in the Philippines.
1.1.3.2 Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer
The auriferous eluvial material consisted mainly of weathered debris and disintegrated bedrock carrying free gold. Certain eluvial auriferous deposits take the form of talus accumulations. A typical example of this type of placer occurs near the Belaya Gora deposit in the Lower Amur region of Russia.
Placer mining is the technique by which gold that has accumulated in a placer deposit is extracted. Placer deposits are composed of relatively loose material that makes tunneling difficult, and so most means of extracting it involve the use of water or dredging. Panning
The principal gold-mining districts in the Philippines are the Baguio and Lepanto regions in the m Mountain Province, the Aroroy district in Masbate, the Paracale district in Camarines, and the Cansuran district in Mindanao. The first two are lode- _ gold district; the last two are placer-gold districts.
MINING CLAIMSA mining claim is a parcel of land for which the claimant has asserted a right of possession and the right to develop and extract a discovered, valuable, mineral deposit. This right does not include exclusive surface rights (see Public Law 84-167).There are three basic types of minerals on federally-administered lands: locatable, leasable, and salable.

Alaska Placer Deposits. Much of the gold produced in Alaska was mined from placers. These deposits are widespread, occurring along many of the major rivers and their tributaries. Some ocean beach sands also have been productive. The principal placer-mining region has been the Yukon River basin which crosses central Alaska.
This was somewhat of an informal preliminary evaluation into several areas of the Philippines to see if we could find any promising commercial dredgingopportunities there. A longtime close friend of mine and fellow gold dredger, John Koczan, had been spending a lot of time in the Philippines with his job, so he knew his way around pretty well.
You can go placer mining wherever gold is found in placer deposits. For gold, I'd suggest looking in Alaska, or California, or Arizona, though many other states also have gold in at least small ...
Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits.
Correct Topography: As a general concept, the coarser gold does tend to hang up farther upstream. In the deserts, most of the best residual placers form in areas with moderate to flat slopes. Extensions of Known Mineral or Placer Areas: Other than pipe shaped bodies, most small scale gold deposits have a linear component. It is fairly common ...
