Location Method: Data Compilation
Access Description: The site is taken from assessment work and compilation.
1951 Dominion Gulf flew a regional airborne magnetic survey in which the magnetic anomaly associated with the carbonatite was recognized. Ground examinations failed to locate any outcrop. 1954 Dominion Gulf re-examined the area on the ground and identified carbonatite boulders in the area. 1959 Falconbridge Nickel carried out a ground magnetic and geological mapping program combined with pitting. This resulted in the identification of apatite and some magnetite - vermiculite mineralization. 1977 Hygrade Corrugated Containers carried out an exploration program which consisted of ground geophysics (magnetic and radiometric), trenching, and drilling.
Province: Kapuskasing Structural Zone
Geological Age: Paleoproterozoic Geochronological Age: 1872 +/- 13 MA Geochron. Age Ref.: OGS STUDY 33, P. 10
May 10, 2016 (A Wilson) - The complex consists of sovite and silicocarbonatite and included blocks of fenitized gneissic wallrock. The lithologic distribution is likely arcuate as a result of emplacement of a series of cone sheets into brecciated and fenitized gneisses. The complex is enclosed within the gneisses of the Kapuskasing Structural Zone.

Dec 07, 2005 (S Fumerton) - The carbonatite intrusion has been described in considerable detail by Sage (1983).
May 10, 2016 (A Wilson) - The complex consists of an alternating series of sovite, silicocarbonatite and fenitized wall rock. The complex probably represents a series of sovite and silicocarbonatite cone sheets emplaced into the surrounding brecciated gneisses. The dominant rock exposed during trenching was calcitic carbonatite containing apatite, magnetite, amphibole, vermiculite or biotite-phlogopite and red-brown dolomite dikes.

May 10, 2016 (A Wilson) - On the basis of assays, the U and Nb occur together suggesting their presence together in the same mineral possibly pyrochlore. In those sections containing U values Nb2O5 values up to 598 ppm were reported. Vermiculite is present in the weathered in carbonatite and could be an extraction by-product of any apatite accumulations. No concentrations of vermiculite are reported. Magnetite occurs in a number of bands, but is not sufficient to support a mining operation.
May 10, 2016 (P Bousquet) - Drill hole B2 returned an assay of 12.78% P2O5 over 77.8 ft (T-3671, Study 33). There are other wide intersections, but they have lesser grades.
