OSP SakhGrE (Yuzhno-Sakhalinsk, a stand-alone structural unit of JSC Far East PGO, a part of the ROSGEO state holding) completed the two-year long package of work for coal in the Lakhskaya area.
The prospect covers the territory of three northern administrative districts of the Sakhalin Region: Okhinsky, Nogliksky, and Aleksandrovsk-Sakhalinsky. The federal budget-funded prospecting for power plant coal is expected to take three years, until the end of 2019.
Over two main surveying season, the enterprise specialists have performed the site investigations, magnetic and electrical studies, and manual trenching. Manual trenches verified the prospecting traverses. Drilling of prospect wells exposed a 1.65 m thick composite bed. There are several up to 7.9 m thick coal beds in the area.
Lakhskaya coal-bearing area is the first in the history of the development of the north of Sakhalin, the resource potential of which is estimated at 1 billion tons of power plant coals. Based on the results of the work of Sakhalin geologists, the inferred resources by the P2+P1 categories to a depth of 300 meters will be calculated.
Currently, the work is suspended because of weather conditions and the lack of appropriate roads throughout the length of the Lakhskaya area. The roadbed cleaning has begun. It is expected to resume drilling activities in the first quarter of 2019. The final exploration report, including recommendations on further geological survey within the area, will be submitted to the customer before the end of 2019.
