The Sunshine No. 2 (L. 15033) occurrence is located along the northeastern arm of Lime Creek at an elevation of approximately 1140 metres and approximately 700 metres west of the past-producing Jersey (MINFILE 082FSW009) mine.

Regionally, the area is underlain by quartz arenite sedimentary rocks of the Neoproterozoic to Lower Cambrian Hamill Group, undivided sedimentary rocks of the Cambrian Laib Formation and fine clastic sedimentary rocks of the Ordovician Active Formation. The rocks are folded into a series of generally north-trending anticlines and synclines. To the east and west these have been intruded by granodioritic rocks of the Cretaceous Anstey pluton, and to the north and south small bodies of syenitic to monzonitic intrusive rocks are exposed.

Locally, scheelite is reported to occur as disseminations in skarnified limestones of the Reeves Member of the Lower Cambrian Laib Formation.

Also, as defined by diamond drilling, a 3.7- to 13.8-metre wide, northeast-trending and moderately east-dipping zone of quartz flooding and veining within silicified limestone of the Reeves member of the Lower Cambrian Laib Formation hosts up to three separate, 1- to 2-metre wide, bands of massive pyrrhotite and pyrite with minor arsenopyrite, chalcopyrite, galena and sphalerite mineralization. The limestone and sulphide bands are cut by steeply dipping lamprophyre dikes. The zone has been traced by diamond drilling over a strike length of approximately 500 metres and downdip for over 100 metres.

In 1947, samples from pits and trenches on the Hal No. 2 Crown grant, located approximately 250 metres to the northwest, yielded up to 0.10 per cent tungsten trioxide over 1.05 metres and 0.09 per cent tungsten trioxide over 1.8 metres (Assessment Report 00021).

In 1994, a drillhole (J94-01) yielded 27.30 grams per tonne gold, 34.4 grams per tonne silver with greater than 0.01 per cent cadmium, 1.0 per cent lead and 1.0 per cent zinc each over 0.9 metre from a zone of massive sulphide mineralization (Assessment Report 23883).

In 2018, diamond drilling, in the area of the 1994 drillhole, yielded intercepts up to 0.5 gram per tonne gold over 8.36 metres, including 2.05 grams per tonne gold, 0.217 per cent lead and 0.228 per cent zinc over 1.32 metres in hole JE18-01 (Assessment Report 37833).

The area has been historically explored in conjunction with the nearby Emerald Tungsten (MINFILE 082FSW010) and Jersey (MINFILE FSW009) mines.

In 1947, Canadian Exploration Ltd. completed a program of geological mapping on the area.

In 1994, Sultan Minerals Inc. completed a program of 11 diamond drill holes, totalling 1323.5 metres, on the area in conjunction with the nearby Emerald Tungsten (MINFILE 082FSW010) mine. Two of the drillholes, J94-01 and J94-02, were completed on the Sunshine No. 2 Crown grant. In 1995 and 1996, programs of geochemical sampling, geological mapping and a 510 line-kilometre airborne geophysical survey on the area.

In 2018, Margaux Resources Ltd. completed five diamond drill holes, totalling 1125.9 metres, on the area to test previously identified EM conductors.
