Last summer, I managed to collect a small amount of material on the mineralogy of the surroundings of the Karmankulsky Cordon, located on the left bank of the River M. Irimel about 45 versts to the SW of the Miass station. Along the right bank of the River Irimel, there is a series of large pits, formerly mined, but now abandoned for the extraction of iron ore; on the left bank, however, there are only small prospecting pits. In the waste dumps of the previously mined pits, it was possible to find, in addition to chromite and rhodochrome, very poor kemmererite and small but well-formed crystals of uvarovite; both of the occur as crusts on chromium iron ore. In the survey pits (on the left bank of the Irimel River), in addition to chromite, small crystals of vesuvianite and magnetite were also found.

In the summer of 1901, I managed to inspect the Kerch mines, where I obtained a fragment from a large barite specimen with the note that it was found in a mine located near the plant. The specimen in its original size was about 2 kilos in weight and had the shape of a mushroom; completely dense both in its central part and at the edges; wax-yellow in color with a white streak, translucent in small pieces and transparent in thin fragments; the pereferical layer about 3 mm thick is yellowish-white and cloudy. The structure is radiant. March 20, 1909
