Aurora holds the mining license for a large area of alluvial gold. Alluvial gold mining has its own specifics - alluvial gold is located below the top level of lighter gravel and sand, at the base of a river or stream. Gold mining in bulk is the process of extracting gold from these deposits, rivers and streams, and, as a rule, is considered the most environmentally friendly method of gold mining as a result of reduced environmental impact compared to open pit or even underground mining.

Alluvial gold deposits form over time where a river runs, or has previously run through ground which is rich in gold. The erosive power of the water removes the surrounding rock due to its comparative low density while the heavier gold resists being moved. Alluvial gold usually takes the form of dust, thin flakes or nuggets. Alluvial gold can also be moved by fast moving water over shorted distances and similarly deposited at the bottom of the riverbed.

Alluvial deposits are either dredged from the pond and river bottoms or sluiced from banks and floodplains with high-pressure hydraulic hoses. Alluvial deposits require little or no comminution; they are usually concentrated by gravity techniques such as jigging or tabling, in which a slurry is passed through jigs or over grooved or ridged tables that retain the denser gold particles while allowing the much less dense sand and gravel to pass over.

The first stage in alluvial gold mining is to take the dredged river bed material and separate the small sand faction (where the gold is found) from the larger mineral fraction. In a typical alluvial mining process physical separation methods such as screening and gravity separation are employed to separate the gold from the mineral fraction.

The second stage in a gold dredge is a placer mining machine that extracts gold from sand, gravel, and dirt using water and mechanical methods.

A large gold dredge uses a mechanical method to excavate material (sand, gravel, dirt, etc.) using steel "buckets" on a circular, continuous "bucketline" at the front end of the dredge. The material is then sorted/sifted using water. The material that is washed or sorted away is called tailings. The rocks deposited behind the dredge (by the stacker) are called "tailing piles."

Aurora group is an experienced gold miner using an advanced dredge system. The advantage is that the drum system can handle clay materials and even very hard clays, breaking the clay with a cutting knife before directing it to several layers of separation and finally sluice boxes. Gold is separated from clay and extracted effectively and easily. This is the best method to process gold trapped in sticky soil and clay material. Gold is separated from clay and extracted effectively and easily with a capacity of 400 cbm / hour.

Dredger machines use diesel fuel which is brought using ships and hovercraft. To help the mining operations we will build a helipad and use helicopters to send staff and for certain logistics, as well as to send processed gold out of the mining site. The size of the gold to be processed in the river varies from the most refined such as sand to the size of  corn kernels. Gold will then be refined and cast into the form of 1kg gold bars, which are very popular in the international gold market.
