A sample with iron ore and amphibolite—metamorphic green, black rock with serpentinite and magnetite. High quality iron ore starts at a depth of 360 meters and extends at least to 1100 meters. Resources—734 millions tonnes, but exploitation of them is ecologically sensible due to the proximity of unique Dzukija National Park.
