Access Description: The property is located in east-central Rickaby Township, approximately 3.3 km northeast of Seven Foot Falls on the Sturgeon River and 1,750 m south of the Kenty Showing. Travel north from Nezah (10.1 km west of Jellico) on secondary Highway 801 for 12.9 km and turn northeast on the River Road for approximately 12.9 km to Rickaby Township. Proceed east on gravel roads for about 2.6 km to the property.
1951: The claims covering the occurrence were staked by Gordon Dickson. 1952: Optioned to Chesterville Mines Ltd, who completed a diamond-drill program consisting of 14 holes. The option was later dropped. 1967: Claims restaked and optioned to Rio Tinto Canadian Exploration Ltd. Detailed geological mapping and electromagnetic and magnetic surveys were conducted. 1968: Geological mapping and a Turam EM survey were conducted.

Geological Age: Archean
Dec 07, 2005 (B Nelson) - In the area of the showing there is a high proportion of felsic rocks within a volcanic succession having a stratigraphic thickness of 1200 to 1500 m. The major rhyolitic rock units appear to form two groups, separated by a band of andesitic and dacitic flows and pyroclastic rocks. In general, units within the predominantly felsic metavolcanic sequence are similar in appearance and composition. The distinction between the units can only be made on the basis of subtle color differences and the presence or absence of such features as quartz and feldspar phenocrysts, amygdules, and spherulites. Most of the metavolcanics on the property are cut by irregularly shaped narrow intrusions of andesitic feldspar porphyry which are probably of early Precambrian age. An east-trending lamprophyre dyke about 9 m wide has been traced over several hundred feet in the vicinity of the Kenty showing. Several north-trending Keweenawan diabase dykes up to 30 m wide have been recognized on the property and coincide with several linear ground magnetic anomalies.

Dec 07, 2005 (B Nelson) - Spherulitic and flow banded rhyolitic rocks occur in both of the felsic-rich groups in the vicinity of the sulphide showings. Most of the felsic rocks, however, are fine pyroclastic rocks such as tuff, crystal tuff, lapilli tuff, and derived sericitic schist. Coarse-grained intermediate to felsic pyroclastics are also common. The more mafic rocks are basaltic and andesitic agglomerate, tuff breccia and massive and amygdaloidal andesitic flows.

Dec 07, 2005 (B Nelson) - Chesterville Mines Ltd., in 1952, took samples providing the following values: HOLE 1 (over 0.30 m): 0.01 oz/ton Au, 14.3 oz/ton Ag, 4.63% Pb, 7.05% Zn. HOLE 4 (over 1.0 m): 0.01 oz/ton Au, 4.86 oz/ton Ag, 0.11% Cu, 2.12% Pb, 7.53% Zn.
Dec 07, 2005 (B Nelson) - Feldspathization of all the volcanic rock types makes it difficult to distinguish between individual flows or pyroclastic units on the basis of petrographic examination.
