The Hed Northwest showing is about 6 kilometres east of McNulty Creek and 19.5 to 20.5 kilometres north-northeast of the town of Hedley.

The occurrence is hosted in hornblende biotite granodiorite of the Early Jurassic Bromley batholith, at or near the contact with the Middle Jurassic Osprey Lake batholith to the north.

Mineralization consists mostly of veinlets of chalcopyrite, chalcopyrite-bornite, chalcopyrite-bornite-molybdenite and molybdenite, and rare pyrite-chalcopyrite veinlets. Chalcopyrite and molybdenite are also disseminated in the granodiorite. Drilling and mapping has revealed sporadic zones of copper mineralization over an area trending north-northwest for 1000 to 1500 metres. A hole yielded 0.091 per cent copper, 0.0023 per cent molybdenum and 0.92 gram per tonne silver over 15.25 metres (Assessment Report 9929, page 32, hole 21, 61.0 to 76.25 metres). A second hole, 750 metres south-southeast of hole 21, graded 0.075 per cent copper, 0.0031 per cent molybdenum and 0.8 gram per tonne silver over 18.3 metres (Assessment Report 9929, page 27, hole 18, 45.75 to 64.05 metres).

The showing was discovered and staked by Anaconda American Brass Ltd. in 1969 after anomalous molybdenum and copper values were obtained in a stream silt survey. The company and Canex Aerial Exploration Ltd. conducted various geological, soil geochemical and geophysical surveys between 1970 and 1972. Anaconda Canada Exploration Ltd. drilled 10 percussion holes totalling 946 metres in 1981. The property was held by Verdstone Gold Corp. and Amcorp Industries Inc. in 1996. Jasper Mining Corporation conducted geochemistry and geophysical surveys and diamond drilling on the property from 2006 to 2011.
