Located one kilometre north of Tokatoka. All the basalt is strongly porphyritic with phenocrysts to 2 mms of plagioclase, clinopyroxene and olivine. The olivine may be altered to chlorite and serpentine. Opaque minerals are dominated by titanomagnetite, with some pyrite, pyrrhotine.

At the basalt contact are unusual minerals rankinite, kilchoanite, larnite and spurrite, with ubiquitous hydrogrossular, cut by a network of wollastonite-grossular-scawtite veins and hydrothermal precipitates of torbermorite, and calcite, with lesser afwillite, gismondine, and foshagite. Microscopically, schorlomite and ferrosahlite is noted.
