The Rohne prospect is located at 396 metres elevation on the eastern slopes of Mount Kruger, 3 kilometres southeast of Osoyoos, British Columbia. The Dividend-Lakeview past producer (082ESW001) lies 1.75 kilometres to the northwest.
Little information is available on the early history of the Rohne (Lot 2676) Reverted Crown grant. Work presumably began before 1903 when the claim was first Crown granted to J. Rink and associates. Little else was done on the property until 1968 by Granby Mining Company Limited. Exploration on the claim consisted of 1858 square metres of bulldozer stripping and drilling 14 percussion-drill holes. In 1986 and 1987, Markus Resources Inc. conducted extensive exploration in the Dividend-Lakeview area, including on the Rohne property.
The regional geology of the Dividend-Lakeview area consists of medium to coarse-grained granodiorite of the composite Middle Jurassic Similkameen batholith. To the west this includes alkali syenite and nepheline syenite of the Kruger intrusion. The Fairview intrusion outcrops to the north. The Similkameen intrusion extends from 10 kilometres north of the Canada-United States border, south into Washington state. The granodiorite is grey-green, medium to coarse grained and dominantly composed of quartz, plagioclase and hornblende. The Similkameen batholith has intruded metasediments and metavolcanics of the Carboniferous to Permian Kobau Group. Intensely folded and metamorphosed quartzite, greenstone, phyllite, chlorite or mica schist with intercalations of dioritic rocks and sparse limestone lenses comprise lithologies. To the west lie a series of highly sheared schists, greenstones and quartzites known informally as the Kruger Schists. The greenstone has been highly sheared in many areas associated with emplacement of the Similkameen intrusion and other intrusions. Shear zones strike southeast and dip moderately to steeply northeast and southwest. Local variations occur however.
Silicification composed of quartz pods, stringers and veins is common throughout the greenstone and in quartzite near the southwest corner of the Gold Hill claim. Minor carbonate is also present.
The Rohne prospect consists of numerous chalcopyrite mineralized quartz veins with malachite staining and epidote-rich skarns hosted in chloritized greenstone.
These veins and skarns were sampled in 1987 with encouraging results. Sample G-87-025, a 0.7-metre chip sample from an opencut yielded 0.50 per cent copper, 0.16 gram per tonne gold and 4.4 grams per tonne silver (Assessment Report 16074). The sample was composed of chlorite and epidote-altered greenstone with malachite and limonite altered quartz veining. Mineralization consisted of minor pyrite. Sample G-87-028, a 1.5-metre discontinuous chip sample, yielded 0.41 per cent copper, 0.26 gram per tonne gold and 3.9 grams per tonne silver (Assessment Report 16074). This sample consisted of quartz veining cutting altered intrusions and greenstone with abundant epidote, minor malachite and a 10-centimetre pyrite lens.
