Project F was targeted because of to the presence of thick, shallow-dipping coking coal seams outcropping only 18km from a road and 35km from its operating coal port at Beringovsky, on the Pacific coast.
Drilling through the 2013 and 2014 winter season resulted in discovery of large strike extensions of the seams, substantially increasing total resource tonnages and further increasing the tonnages in measured and indicated categories by nearly 120%.
Resource consultant Resolve Geo estimated the 72.3Mt of coal resources at Project F includes measured resources of 12.6Mt, indicated of 13.2Mt and inferred of 46.6Mt.
About 58.6Mt of the total coal resource is in the open pit domain, less than 150m from surface.
Below 150m, the resource holds a further 13.7Mt, providing upside for underground operations.
The resource estimate is based on 116 drill holes totalling 9698m, outcrop mapping and sampling, and structural interpretations of satellite photography and Landsat imagery.
