Red Hills Massif is 120 km2, approximately 15 km long and 8 km wide. includes Two Tarns Harzburgite, Plagioclase Zone, Plateau Complex, and Ellis Stream Complex, from east to west. Clinopyroxene-rich peridotite and (olivine) clinopyroxenite outcrops account for the westernmost Ellis Stream Complex (or Ellis Stream Shear Zone (ESSZ)). The equilibrium temperature is normal (~1000 °C) while the pressure is low (0.5 GPa) due to the close proximity to the crustal area. Rare earth element (REE) data reveal that the complex is enriched by the melt-rock reaction and that clinopyroxenites originate from frozen melt.

The Red Hills massif is part of the overall Dun Mountain Ophiolite Belt, but is not part of Dun Mountain itself, which is some 40km north east.
