Capsule Geology

Hydromagnesite deposits are being formed today in many of the playas of the Chilcotin Plateau, a region characterized by a semi- arid climate, relatively mature topography and, in some areas, internal drainage systems.

The Fletcher Lake hydromagnesite showing occurs within Recent lacustrine sediments developed on older glacial gravels and Tertiary volcanic rocks. Like many of the small lakes of the area, Fletcher Lake becomes dry over summer months allowing the accumulation of hydromagnesite within its sediments during water evaporation.

There are 350 tons of hydromagnesite estimated.
