• Stones of the deposit

In the Kam’yantsi plot granite is coarse-grained, from pink-gray to grayish-pink, porphyry, slightly trachytoid. Within the Lisove section, there are four varieties of granite: gray-pink, porphyry-shaped granites (similar to those found in the Kam’yantsi section); granites pink, medium-grained, leucocratic; granites gray, light gray, medium-grained; enderbites black, dark gray, fine-grained.

• Reserves and Resource as of 01.01.2018.
