The Prince’s occurrence is located approximately 2.2 kilometres north of the mouth of Youghpan Creek on Holberg Inlet.
The area is underlain by rhyolite, felsic volcanics and mafic volcanics of the Middle Jurassic Bonanza Group (Holberg volcanic unit) and sediments of the Lower Cretaceous Longarm Formation (Queen Charlotte Group). The volcanics have been intruded by quartz diorite to granodiorite of the Early to Middle Jurassic Island Plutonic Suite.
Locally, oxidation of pyrite in Bonanza volcanics leads to the formation of limonite. On hillsides and hilltops the limonite is fairly pure. In depressions the limonite is present as bog iron, mixed with transported rock and peat.
Thicknesses from a few centimetres to 2 metres were noted, although in one place a thickness of 5.5 metres was obtained by drilling (Canmet Report 47, 1909, page 18). The greatest thicknesses are present in the vicinity of two creeks on the old Eagle and Sunrise claims (MINFILE 092L 089), part of the Prince's group.
A sample collected from an opencut contained 54.46 per cent iron, 0.15 per cent sulphur, 0.038 per cent phosphorus and 2.32 per cent insoluble matter (Canmet Report 47, 1909, page 18; see Sunrise - MINFILE 092L 089).
During 1969 through 1973, BHP-Utah Mines completed programs of soil sampling, geological mapping and ground geophysical surveys on the area as the Expo claims. During 1982 through 1984, programs of rock and silt sampling and geological mapping were completed on the area as the Wanda claims. In 1985, Homestake Canada Inc. prospected and sampled the area immediately southeast as the Wan claim. In 1986, a program of rock and soil sampling was completed on the Wanda and Stat claims. In 1987, Rochester Minerals Inc. completed a program prospecting and stream sediment sampling on the area. In 1988, Moraga Resources Ltd. and BHP-Utah Mines completed a program of geological mapping and rock sampling rock sampling on the area.
In 1990, Acheron Resources Ltd. soil and rock sampled the area as the Wann property. Later that year, Moraga Resources Ltd. optioned the property and completed 17 rotary drill holes, totalling 1749.6 metres, on the area. In 1992, a 10.5 line-kilometre combined ground induced polarization and magnetic survey was completed. In 1993, a program of 14 diamond drill holes, totalling 1786.3 metres, was completed on the area.
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. In 2017, North Island Mining Corp. completed a spectral analysis program on the area as the Pemberton Hills property. The following year, nine diamond drill holes, totalling 3401.6 metres, and a 13.8 line-kilometre induced polarizations survey were completed on the property. In 2019, a 20.5 line-kilometre induced polarization survey was completed on the area as the Pemberton Hills property.
