Capsule Geology

The Mona carbonatite occurrence is located near the east side of the North Thompson River, across from the mouth of Miledge Creek.

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.

The Mona carbonatite is interpreted to be a late stage remobilization of carbonatite from the Fir (MINFILE 083D 035) system.

In 2010, a continuous chip sample of fenite at the Mona carbonatite averaged 0.1474 per cent niobium and 0.66 per cent total rare earth elements (TREE) over 28 centimetres, while two grab samples of carbonatite yielded 0.1743 and 0.0006 per cent niobium with 1.36 and 3.66 per cent total rare earth elements, respectively (Kulla, G., Postolski, T. (2013-06-21): NI 43-101 Technical Report on Mineral Resource Update - Blue River Tantalum–Niobium 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.
