NTS Grid: 52F06SW

Point Location Description: Transfer

Location Method: Conversion from MDI

Access Description: The property is readily accessible by travelling 16 km from Dryden along Highway #502 to Century Road, a primary logging road established by Great Lakes Forest Products of Dryden, Ontario. This logging road was extended to the northeast boundary of the property in July 1984. The distance from the property to Highway #502 along Century Road is 65 km. Initially, fixed-wing float-equipped aircraft were used. Presently, several bulldozer and drill roads permit access on to the property.

Exploration History

1983-84: a program of geological, geophysical and geochemical survey, trenching and diamond drilling was carried out by Derry, Michener, Booth &. Wahl on the Rowan Lake property held by Dejour Mines Limited, Nova-Co Exploration Limited and Brinco Limited. 1984: The 57 claim Rowan Lake property is held by Dejour Mines Limited and Nova-Co Exploration Limited. Under the termns of a Joint Venture agreement dated August 9th, 1984 Briilco Limited has provided project funding since then to have earned a 35% interest. Dejour, as operator, and Nova-Co currently hold respective interests of 47% and 18%.

Geology Comments

Nov 03, 2009 (D Scholtz) - Several gold showings of the Kakagi-Rowan Lake area appear to be confined to shear zones within altered mafic volcanics (Blackburn and Janes, 1983). With respect to property geology approximately 90 km of geological mapping was carried out using our previously established cut grid with a 100 metre line spacing. Geological mapping has revealed the presence of predominantly mafic flows in the northern and southern portion of the property area. The orientation of the lithologies in the central portion of the grid is parallel to an east-northeast regional magnetic trend and consists predominantly of weakly to strongly foliated mafic flows with local shear zones. Minor lenses of mafic to felsic pyroclastic rocks occur within the central and northern portions of the claim group and are thought to be part of the younger Cameron Lake volcanic sequence. Granitic dykes and/or sills and quartz feldspar porphyry, associated with the Atikwa Batholith and, gabbro dykes/sills intrude the massive basaltic rocks in the northern portion of the claim group. Alteration in the form of pervasive carbonatization, as well as silicification quartz-carbonate veining and sericitization appears to be stronger within a central foliated horizon than within the enclosing northern and southern massive mafic volcanic rocks where alteration is minor or absent. Alteration appears to be strongest within the zones of shearing. Trace to 10% disseminated and banded pyrite is usually associated with the alteration. Several geophysically interpreted faults and lineaments cut the property and all rocks within the central horizon have been foliated and locally sheared. These zones of shearing, with associated alteration and mineralization, are somewhat similar to those of the Monte Cristo gold occurrence.

Jul 06, 2022 (Q Unknown) - Rowan Lake lies near the western extremity of the Archean Savant Lake-Crow Lake metavolcanic-metasedimentary belt (Trowell, et al., 1980). Within the Kakagi-Atikwa Lakes area, the region is divided by the northwest-southeast trending Pipestone-Cameron Fault Zone. Southwest of the fault, the region is underlain by two sequences; the lower Snake Bay and Katimiagamak Lake volcanics and the upper Kakagi Lake volcanics. The Snake Bay volcanics in the northwest are composed of a thick sequence of predominantly pillowed mafic flows. In the south, the Katimiagamak Lake volcanics of similar lithology and thickness have been intruded by gabbroic sills. The Kakagi Lake Group consists of intermediate pyroclastics and metasediments that have been intruded by differentiated ultramafic to mafic sills. Northeast of the Pipestone-Cameron Fault Zone, the Rowan Lake volcanics to the north and the Brooks Lake volcanics to the south are overlain by the Cameron Lake volcanics. The Rowan Lake and Brooks Lake Volcanic sequences are composed predominantly of pillowed mafic flows whereas the upper Cameron Lake rocks are of a mixed sequence of intermediate and mafic flows and pyroclastics with minor felsic flows and tuffs. Several younger stocks and batholiths, ranging from felsic to ultramafic in composition, have intruded all rock units. A major fold structure, the Shingwak Anticline, has deformed rocks northeast of the Pipestone-Cameron Fault. The Cameron Lake gold deposit of Nuinsco Resources Limited and Lockwood Petroleum Incorporated, and the Monte Cristo gold prospect of Nuinsco Resources, both lie on the south limb of the Shingwak Anticline within the Brooks Lake volcanics and near to the transition to the Cameron Lake volcanics. Trace to 10% disseminated and banded pyrite is usually associated with the alteration. Several geophysically interpreted faults and lineaments cut the property and all rocks within the central horizon have been foliated and locally sheared. These zones of shearing, with associated alteration and mineralization, are somewhat similar to those of the Monte Cristo gold occurrence.
