Canadian International Minerals Inc (CVE:CIN) announced that mineralized carbonatite and related alkaline rocks in significant intercepts have been intersected in the 2011 Phase I diamond drilling program on the Carbo rare earth element property.
The press release is quoted as saying:
Carbonatite and related alkaline units can be up to several tens of metres in thickness. These units are generally planar, and parallel to the host rock (phyllite) fabric, which is consistently subvertical, and trending approximately 140 degrees on surface. Occasionally the carbonatite occurs as crosscutting dykes or veins. The carbonatite is typically a combination of calcite, dolomite, and/or ankerite with a variety of accessory minerals including rare earth minerals. Many of the alkaline dykes are commonly sulphide-rich, and occasionally host sodalite. The host rocks around the carbonatite are commonly altered to varying degrees. The alteration may include bleaching, hornfelsing, riebeckite, and flooding of feldspar-feldspathoids.
