Dec 03, 2014 (R Tuomi) - The Hornby Lake greenstone belt consists dominantly of pillowed to massive mafic to komatiitic flows with subordinate intrusions of mafic to ultramafic composition. Minor lithologies include wacke sediments, intermediate metavolcanics, and sulphide-facies iron formation. The Hornby Lake greenstone belt is enclosed by batholiths of tonalitic to granodioritic composition. Both the supracrustals and enclosing batholiths have been affected by a regional deformation that has produced a stong north-south-trending folliation.

Dec 03, 2014 (Mark Puumala) - Baker (1968) refers to this occurrence as Discovery No. 2 and the Partridge showing. The occurrence is reported to be located on the south shore of Fardum Lake, and is described as a northeast-striking zone of mineralization that is localized in an approximately 2.4 m wide zone at the contact between intermediate to mafic metavolcanics (andesite) and a diorite intrusion. Mineralization is described by Baker (1968) as consisting of disseminated pyrrhotite and chalcopyrite. The mineralized zone is also reported to have undergone extensive shearing. The showing is reported to have been channel sampled. However, no assay results from this surface sampling are provided in the assessment file (assessment file RL 1968 53C/SW #1). Anomalous copper and nickel assays were reported from samples collected from two diamond drill holes that were advanced on this showing by Asbestos Corporation (assessment file RL 1968 53C/SW #1). The most notable assays were 0.11% Cu , 0.11% Ni and 0.04 oz/t Ag from a 2.6 m sample collected from a section of core that intersected the mineralized zone in drill hole No. 5. A 4.6 ft. sample from DDH No 8 intersected 4.6 ft of 0.07% Cu and 0.07% Ni.
