Last summer I managed to collect a small amount of material on the mineralogy of the surroundings of the Karmankul cordon, located on the left bank of the Кiver M. Irimel about 45 versts to SW from 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 there are only small survey pits. In the dumps of previously mined pits, it was possible to find, in addition to chromium iron ore and rhodochrome, very poor kemmererites and small but well-formed crystals of uvarovite; both of them are like crusts on chromium iron ore. In the survey pits (on the left bank of the Irimel River), in addition to chromium iron ore, small crystals of vesuvian and magnetic iron ore were also found.

In the summer of 1901, I managed to inspect the Kerch mines, where I obtained a fragment from a large piece of barite with the date that it was found in a mine located near the plant. The piece 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; waxy yellow with a white line, translucent in small pieces and transparent in thin fragments; the pereferical layer is about 3 mm thick. yellowish-white, cloudy. The structure is radiant. March 20, 1909
