The H1510 occurrence is located in the northeastern headwaters of Hushamu Creek, approximately 2.3 kilometres east of the eastern end of Hushamu lake.

Regionally, the area is underlain by northwest-trending belts of basaltic volcanics and carbonate sedimentary rocks of the Upper Triassic Karmutsen and Quatsino formations (Vancouver Group) and mafic volcanics and sediments of the Upper Triassic to Lower Jurassic Bonanza Group (Holberg volcanic unit, Nahwitti River wacke and Parson Bay Formation). These volcanic and sedimentary rocks have been intruded by granodioritic rocks of the Early to Middle Jurassic Island Plutonic Suite.

Locally, a road (H1510) cut exposes a clay-altered quartz-feldspar porphyry hosting veins, up to 0.2 metres wide, of pyrite, chalcopyrite and bornite. The veins strike 070 degrees and dip moderately to the southeast.

In 2005, a grab sample (379379) assayed 0.11 gram per tonne gold, 18 grams per tonne silver and 2.58 per cent copper (Assessment Report 28375).

The area has been explored since the 1960s in conjunction with the nearby Hushamu (MINFILE 092L 240) occurrence. In 2005, Luminar Resources Corp. completed a program of rock, silt and soil sampling, geological mapping and a 2687.0 line-kilometre airborne electromagnetic survey on the area.
