stage in the exploration process that permits informed speculation about the type or types or mineralization from which the alluvial gold is derived. Many workers have investigated the link between the composition of alluvial native gold grains and potential sources, examples being studies of Witwatersrand gold (11, 12), and gold from the Yukon ...

beginning with mineral ore exploration and ending with the post-closure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. 1.1.1 Exploration A mining project can only commence with knowledge of the extent and value of the mineral ore deposit.

grains of gold per sample, and seven yielded 0.04 to 0.50 g/m 3. Subsequent sampling along the right bank of the Kocha River and along the headwaters of the right tributary of the Yaftal River found a permissive area (14 km 2) underlain by Pliocene conglomerate. Ten or more grains of gold were found in each of four samples (Semionov and others, 1967).
medium size ore bodies already located. Our first step was to do a geomagnetic survey around the known pay gravels. Lines were spaced at 100' and readings taken every 20'. The data was corrected for diurnal variations and magnetic contour maps were prepared. Distinct anomalies ranging from 50-150 gammas were noted

Alluvial gold mining was mostly dominated by expatriates in those early gold rushes. That trend changed when indigenous people decided to go into mining for the first time in 1949, along the Wanion River. The transfer of skills and knowledge of alluvial gold mining took place in the 1950s and 1960s when many residents, especially around the

Alluvial gold exploration is aimed at recognizing areas of anomalous gold content as evidenced by the nature of the drainage system, its age, geomorphic history and other features of the geological environment including the provenances. Subsequent studies to quantify the findings are governed by the need for accurate data based upon precise measurements.
