The most basic way to extract gold from placer dirt is panning. In panning, dirt is placed in the gold pan, combined with water and then agitated. The agitation in water causes the gold, being more density than the dirt and gravel, to settle to the bottom. The lighter dirt and gravel are then slowly washed out of the pan with water, leaving the gold behind.

The high grade alluvial gold project covers an area of 320 acres 1.3km2 and consists of 18 placer claims and includes a foreign mineral resource estimate of 244,000 ounces gold. The resource, compiled in compliance with Canadian National Instrument 43-101, has been estimated at 1.248Mt, grading 6.1gt gold for 244,000 ounces.
The one distinct variant of alluvial deposits is the existence of beach deposits in certain parts of New Zealand and other places, where gold is found mixed with black sand about low-water mark. These deposits have hitherto been worked by means of a portable sluicing table which is wheeled down to the waters edge at low tide. The concentrative action of the sea on these beaches is such that after every big storm the gold in the black sand is renewed.
The exact amount of overburden cannot be gauged over any big area, and many drill tests are necessary both to establish that fact and to prove the various depths at which bedrock is to be found. The latter information is very essential, as in dredging a sudden rise in the bedrock will often at once make it impossible for a dredge to work. It is quite common to find men who believe that bedrock lies as far from the surface at one spot on an alluvial field as it does at another, or that the thickness of the overburden is the same all over big stretches of country.
The factors that should be considered, therefore, are very various, and are as follows
The only things that are necessary to establish these facts are intelligence and observation, a good knowledge of the country, a keystone or other drill, and a few shafts driven here and there for the purpose of corroborating the results of the drill tests.
These figures will not be approached in many countries, such as West Africa, wherethe native labourer is a stupid and ignorant person and very hard to teach. In many places, such as Surinam, the native is constantly looking for fresh work, and a gang cannot, therefore, be trained with that continuity which will alone ensure good and rapid work.
The drillings extracted from the drill hole by means of the sand-pump are discharged into a wooden trough, 12 ft. by 1 ft. by 1 ft., set on a slight grade. From the trough they are run into the riddle of a rocker, and rocked in the ordinary method adopted for washing gravel. Great care is taken to save all the extremely fine particles of gold, as upon this work depends the accuracy of the tests made. It is customary to clean up results of each pumping, and carefully to note the number of countable colours obtained, and the character of the ground drilled through.
