The Irene occurrence is located 5.5 kilometres south of Nelson. Minor production is recorded from this claim. The claim is now part of the Great Western group claims (082FSW333).

The area is underlain by augite basalt flows, breccia flows and subvolcanic intrusions of the Lower Jurassic Elise Formation, Rossland Group. These have been intruded by plagioclase porphyry of the Late (?) to Middle Jurassic Silver King Porphyry. Shearing and metamorphism is common in the area. Regionally, schists are host to northwest trending shears, parallel to foliation, which host quartz veins with sulphides.

No geological description of the occurrence is available, though it is likely similar to the Silver King occurrence (082FSW176).

Work History

It is recorded that 15 tonnes of ore material were shipped in 1939 which produced 274 grams of gold and 377 grams of silver. In 1945, trenching and surface stripping was done on "mineralized shears".

In 2001 and 2002, Apex completed programs of soil sampling and rock sampling on the area.

In 2017, Prize Mining completed a program of geological mapping, prospecting, geochemical (rock and soil) sampling, a ground magnetic survey, 1180 metres of trenching, environmental (water) sampling and 18 diamond drill holes, totalling 2694.77 metres, on the area as the Daylight property.
