Nizhneamurskaya Mining Company conducts a full cycle of search and exploration for solid minerals:

1. Drafting of the exploration and calculation of their estimated cost of obtaining approvals and permits from government authorities.

2. Conducting field of search, search-evaluation and exploration activities, which include:
Search tours with the selection of samples and shtufnyh referenced sampling points handheld GPS.
Selection metallometric (lithogeochemical) samples in the profile.
Geophysical prospecting methods magneto-and electro with separation of prospective structures for different types of minerals.
The penetration and exploration trenches bulldozers Katarpillar D-7N and T-170 with the grinding blade ditches by hand, geological documentation and trenching through cutting machine company "Hilty", equipped with interchangeable diamond disks.
The penetration deep exploration pits from the selection of the gross and technological samples, their documentation and testing of wall pit furrow.
Drilling core drilling depth of up to 350-450 meters drilling rigs Langir LF-70, LF-90, SKB-4, TSBU-200 with the geological documentation, Photography core and sawing it in stone cutting machines TS-1913 firms "Splitstone. During drilling, drill used wireline company Langir diameter 96 (HQ) and 76 (NQ) mm, which allows to obtain the average yield on the core hole is not less than 90%. Average productivity in drilling is between 600-800 m (SKB-4) up to 1300-1500 m (LF-70, LF-90) on the machine in a month.
The results of geological research in the field are processed on computers. It creates the database on which rebuilt all the necessary graphics (plans, sections, passport wells).
All samples are crushed, grated and analyzed for gold and copper directly on sites of laboratory complex "Zolotynka”. The time between sampling and obtaining the analysis of 3-4 days, which allows the field to make quick adjustments in the planning of exploration on the most promising areas.

3. Analysis and synthesis of data obtained with the writing of the report with the calculation of reserves C1 and C2 and Resources P1 with the defense of a TDF and the SRC, followed by preparing the fields for industrial development of mining companies.

4. Geological, geophysical and topographical plans, maps and sections are printed on the plotter A0.
