Capsule Geology

The RD carbonatite occurrence is located south of Mud Creek and approximately 7.5 kilometres east of the east end of Mud Lake.

The area is underlain by Proterzoic Horsethief Creek Group metasedimentary rocks and derived gneisses. Medium to coarse crystalline sovite and beforsite carbonatite sills intrude the Horsethief Creek rocks.

Locally, a carbonatite occurrence is reported. The occurrence is on strike with the Mud Creek (MINFILE 083D 037) carbonatite and may be part of the same system.

In 1999, grab samples from the RD carbonatite ranged up to a maximum of 0.0118 per cent tantalum and 0.4703 per cent niobium (Chong, A., Postolski, T. (2011-01-31): NI 43-101 Technical Report - Blue River Ta-Nb Project).

The area has been explored in conjunction with the nearby Fir (MINFILE 083D 035) occurrence and a completed property exploration history and regional geology and carbonatite mineralization summary can be found there.
