The Howl occurrence is located about 6 kilometres north of Croydon Creek and 113 kilometres north-northwest of the community of Germansen Landing.

At the showing, tuffs and agglomerates of the Upper Triassic Plughat Mountain Formation (Takla Group) are cut by small quartz-carbonate veins, from 2 to 10 centimetres in thickness. Malachite and chalcopyrite are found in the veins and minor malachite occurs on fracture surfaces in the area. Some mineralization seems to be associated with small ultramafic dikes which intrude the Takla rocks.

In 1992, a sample of the mineralized vein analyzed 1.01 per cent copper, 0.77 gram per tonne gold, 18 grams per tonne silver and 0.03 per cent zinc (Open File 1993-2, Map Number 40).
