Hornblende as a mineral name has been recently discredited. Here it is used as a field name for any dark amphibole for which the exact composition has not been determined. In the past black amphiboles were often identified as hornblende without x-ray or microprobe verification. The names used in the original literature are those which are used here. Hornblende is a very …

-Hornblendite.-Magnetite Pyroxenite.-Dunite.-Monzonite. There is a suggestion of a layered trend of the complex in a NW-SE direction (this is supported by the magnetic pattern). These trends reflect a broadly concentric zonation of lithologies (mafic lithologies in the centre becoming intermediate in moving out from the "core") in the complex.

The primary mineral of economic interest at this prospect is thulite, which is the main ore mined in the area. The deposit has a distinctive lenticular or lens shaped form, with a width measuring approximately 0.91 meters (2.99 feet). The surrounding rock formation in this region is mainly composed of hornblendite.
