The HPH 3 (Pit) occurrence is located south of the Nahwitti River, approximately 1.45 kilometres east-southeast of its mouth on Nahwitti 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, north-trending galena-sphalerite mineralization occurs as fracture fillings and disseminations in sheared and/or silicified Quatsino Formation limestone near a contact with Karmutsen Formation andesites. Quartz diorite of the Island Plutonic Suite is nearby. Magnetite can also be present. Areas of the limestone are altered to skarn. Mineralization is exposed in outcrops and trenches over a strike distance of 135 metres and widths of 1.5 to 4.5 metres.

In 1966, a chip sample (3041) across 2.1 metres assayed 373.7 grams per tonne silver, 3.18 per cent lead and 5.56 per cent zinc, whereas a grab sample (3042) assayed 356.5 grams per tonne silver, 3.18 per cent lead, 4.97 per cent zinc, 0.17 per cent copper and 0.34 gram per tonne gold (Assessment Report 870). Drilling at this time is reported to have yielded 7.38 per cent zinc, 6.91 per cent lead and 369.4 grams per tonne silver over 5.4 metres in hole NL-20 (Assessment Report 17393).

In 1981, a chip sample (HPH-16) assayed 16.80 per cent zinc, 12.30 per cent lead and 222.3 grams per tonne silver over 18.0 metres (Assessment Report 9507).

In 1987, a chip sample assayed 201.1 grams per tonne silver, 4.68 per cent lead and 8.08 per cent zinc across 3.0 metres (Assessment Report 16347).

In 1988, a 2.1-metre chip sample (151) assayed 743.9 grams per tonne silver, 2.55 per cent lead, 3.92 per cent zinc, 0.21 per cent copper and 0.07 gram per tonne gold (Assessment Report 17393).

In 1991, a rock sample (97312) assayed 4.24 per cent lead, 10.0 per cent zinc and 437.9 grams per tonne silver (Assessment Report 21270).

In 2017, a select sample (166430) of outcrop assayed 0.230 per cent copper, 5.32 per cent zinc, 3.47 per cent lead and 296 grams per tonne silver (Assessment Report 37134).

The area has been explored since the early 1930s. In 1948, Western Mines completed an induced polarization and magnetic survey on the area. In 1952, American Smelting and Refining completed a program of geological mapping on the area. In 1966, Giant Explorations Ltd. completed a program of geological mapping and geochemical sampling on the area as the HPH claims. During 1969 through 1972, Giant Explorations Ltd. completed programs of soil sampling and ground and airborne geophysical surveys on the area. In 1979, Loredi Resources prospected and mapped the area as the Gold and Dust claims.

In 1980, Tally Resources Ltd. prospected and mapped the area as the Pato claim. In 1981, Silver Bar Resources prospected the area. In 1984, the area was prospected and sampled by Daiwan Engineering as the Mead claims. During 1987 through 1991, Hisway Resources Corp. completed programs of geological mapping, ground geophysical surveys, geochemical sampling and six drillholes, totalling 381.5 metres, on the area. In 1992, Cameco Corporation completed a program of rock and soil sampling, geological mapping and ground geophysical surveys on the area.

In 2006, New Livingstone Minerals prospected and sampled the area. In 2017 and 2018, Precipitate Gold Ltd. completed programs of rock and soil sampling, gravity surveys and prospecting on the area as the Island Zinc property.
