The STAR showing is located on the east coast of Porcher Island, 11 kilometres north of the village of Oona River and 30 kilometres south of Prince Rupert, B.C.

Isolated magnetite exposures occur along a 5-kilometre, northwest strike, within Paleozoic-Mesozoic metavolcanics and metasediments consisting of chlorite-sericite schists and intercalated limestones and quartzites. The rocks dip about 65 degrees northeast and, in places, contain epidote, garnet and pyrite. The mineralized zone has a maximum width of 60 metres and a drill indicated depth of 45 metres.

The individual outcrops vary in character. Schists bearing discontinuous streaks of fine granular magnetite form zones a few metres wide and less than 15 metres long, and massive magnetite occurs up to 4 metres thick, but less than 10 metres long. The streakiness and lenticularity of the occurrences allowed only grades of about 35 per cent iron.

2019 airborne geophysical, geological mapping and rock sampling/geochemical work on BC Vanadium's STAR property containing the STAR occurrence revealed exploration targets of semi-massive to massive magnetite seams within magnetite+/-chlorite+/-biotite schists with variable enrichments of vanadium rich titaniferous magnetite (between 5 and 95 percent) (See STAR-V mineral occurrence).
