These conductivity variations represent changes in the subsurface, such as clay versus sand potential goldbearing deposits, differences in moisture content, or changes in geologic rock structure. geomodel, inc.s vehicletowed em instruments can cover large areas in one day.
Gold also can be associated with copper and may form placers in the vicinity of copper deposits, although this occurs less frequently. geological events such as uplift and subsidence may cause prolonged and repeated cycles of erosion and concentration, and where these processes have taken placer deposits may be enriched.
Some part have large deposits of gold represented by color yellow and some have few deposits. some part also have large deposits of copper as presented by color blue, and some only have few deposits. in the illustration also, copper is more deeper that gold. miners need to drill deep for copper that gold.
Most rees are mined from placer deposits, bedrock, or clay formations see map below for currently mapped deposits orris, 2002. in the early period of mining rees, they were mined primarily from placer deposits, which are mineral accumulations in rivers and on beaches. placer deposits form when minerals are separated by density as lighter.

Goldbearing arsenian pyrite rocks are found in limestone soil deposits in several regions of china. the journal ore geology reviews reports that up to 55 tonnes of gold have been extracted from arsenian pyrite in mines in shuiyindong, china. most of the gold mined in this area is deemed to be invisible, because it cannot be seen with.
A soft, fatty clay or gouge often flanks the vein in its gold bearing portions. more detailed dead rivers of california tertiary channels rich in gold the auriferous deposit is gravel, mixed with boulders, clay, and sand, rivers of california, and took the gold from their beds, they foundeposit of gravel that more detailed.

The carbonatiterelated deposits host the majority of chinas ree resource and are the primary supplier of the worlds light ree. the reebearing clay deposits, or ion adsorptiontype deposits, are second in importance and are the main source in china for heavy ree resources. other ree resources include those within monazite or xenotime.
The stanley hill clay deposit islay mine located in kootenai county, idaho at an elevation of 2,300 feet. about the mrds data all mine locations were obtained from the usgs mineral resources data system. the locations and other information in this database have not been verified for accuracy.
When this happens, rich placer deposits can get left behind by the river, and remain in place away from the current river channel. bench deposits also occur asiver naturally erodes downward. in these cases,ayer of gold bearing gravel will often be found justew feet above the current high water mark of the river.
Gold will then be deposited on bedrock or false bedrock such as clay or other packed material. as the glaciers themselves melt, the huge quantity of water creates an effective sluicing system that can sort the gold out of gravels. these flows can leave behind very profitable pay zones along the channels cut by the ice melt waters on bedrock.
