It is within this lot that the Carolin mine (MINFILE 092HNW007) was eventually developed. The area is underlain by greenstone assigned to the Lower Triassic Spider Peak Formation in contact with serpentinite of the Coquihalla serpentine belt along a section of the East Hozameen fault. To the east, the greenstone is unconformably overlain by slaty sediments assigned to the Lower and Middle Jurassic Ladner Group. The Montana occurrence comprises a number of 5-centimetre wide quartz veins exposed in an open-cut. These veins are hosted by pyritic greenstone approximately 20 metres west of the Spider Peak Formation/Ladner Group contact. The vein is reported to have contained rich specimens of free gold. A "calcareous lead", approximately 1 metre wide and mineralized with pyrrhotite and pyrite, was also noted in slates to the northeast. Approximately 2 tonnes of high-grade material containing 1151 grams of gold were mined at this location in 1925. In 1973, Carolin Mines completed a program of soil sampling, a 37.0 line-kilometre ground magnetic survey and trenching on the area. In 2012, New Carolin Gold completed airborne magnetic and radiometric surveys, totalling 759 line-kilometres, on the area. The area has been historically explored in conjunction with the nearby Ladner Creek (MINFILE 092HNW007) mine and, more recently, the McMaster (MINFILE 092HNW018) occurrence.
