The Roaring occurrence is located on the south western slope of Mount Curran, north of Roaring Creek and approximately 900 metres east of Rosewall Creek.

The area is underlain by volcanics of the Upper Triassic Karmutsen Formation, Vancouver Group. These rocks consist mainly of pillow basalts and pillow breccia and minor tuffs.

An extensive altered area, reported as calc-silicate alteration, occurs having a relatively flat dip and an approximate thickness of between 25 and 100 metres (Assessment Report 16141). Quartz stringers with pyrite and chalcopyrite cross cut the silicified matrix and clasts of a volcanic breccia. Elsewhere thin quartz veins (2-5 centimetres) with a near vertical dip and southeast trend cut rusty weathered lapilli tuff. These veins contained molybdenite, chalcopyrite and pyrite. Molybdenite was also observed in a quartz- eye porphyry dyke a few hundred metres east of this.

Angular float containing cinnabar, native mercury, and stibnite were located, as were pieces containing sphalerite and galena. Mercury and antimony are generally anomalous in the area. Malachite was found in a similarly altered area across the Rosewall Creek valley, about 1 kilometre to the east of the above occurrences.

In 1987, a program of rock sampling and prospecting was completed on the area as the Roaring 1-2 claims by R.J. Bilquist. In 2008, Duke Mountain Resources Canada completed a program of prospecting and geochemical sampling on the area as the Rosewall-Waterloo property.
