Dec 07, 2005 (A Wilson) - The ore deposit occurs along the basal contact of the lowermost ultramafic flow unit adjacent to the footwall volcanic rocks. All sulphide mineralization occurs at or within 30 m of the footwall volcanic contact. Ultramafic flows average 2.1 m thick and become progressively thinnner up sequence. Spinifex is better developed at higher stratigraphic levels in the ultramafic sequence. The deposit is located approximately 1500 m, along strike, southeast of the Langmuir #2.
