“However,” said Kirkemo, “most placer deposits have been thoroughly reworked at least twice—first by Chinese laborers, who arrived soon after the initial boom periods and recovered gold from the lower grade deposits and tailings left by the first miners, and later by itinerant miners during ...
The search for productive gold deposits requires a good background in prospecting and economic geology (as well as some luck). There are still many deposits to be found, and some of the better areas to search are old, historic, mining districts.It is my experience that it is rare for any...

Avesoro Resources Inc. is engaged in the exploration and development of gold deposits in highly prospective and under-explored areas of Liberia and Burkina Faso. Avesoro Resources Inc. (formally Aureus Mining Inc.) was incorporated and registered in Canada on February 1, 2011 pursuant to the CB...
An integrated exploration approach to map bif-hosted gold deposits in the Rio das Velhas Greenstone Belt, Quadrilátero Ferrífero, BrazilA statistical modeling approach was applied to airborne geophysical data to locate areas favorable for gold mineralization in Rio das Velhas ...
The gold deposits and occurrences are distributed nonhomogeneously throughout the belt as most of them occur in volcano-sedimentary units near the margins of plutons along major tectonic structures, such as faults and folds [14]. Indeed, most of the gold deposits are located along the Moodies,...

However, at the present time, the engineering detection depths of the majority of the metal deposits are less than 300 m due to the complexity of the natural conditions in the Gobi Desert, including limited traffic, weak navigation within the forested areas, mobility, surface conditions, and so...
