Primary Commodities: Gold
Township or Area: Lawrence Lake Area
Latitude: 49° 21' 18.75" Longitude: -93° 29' 29.36"
UTM Zone: 15 Easting: 464307.75 Northing: 5467059.85 UTM Datum: NAD83
Resident Geologist District: Kenora
NTS Grid: 52F06SW
Point Location Description: From map in AFRI 52F05SE0009
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.

1983-4: Dejour Mines Ltd., Nova-Co Exploration Ltd., and Brinco Ltd. had a joint venture agreement and geological, geophysical, and geochemical surveys, trenching, and diamond drilling. 2015: Chalice Gold Mines Ltd. conducted trenching and sampling.

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.

Oct 11, 2017 (C Ravnaas) - Best assays: 3.3 gpt Au over 0.5 and 1.0 m sections in DDH RL-84-03.
Oct 11, 2017 (Therese Pettigrew) - Chalice Gold’s Nova trench located 500 m west of the 1983 drill program area at UTM Zone 15, 463730 m E, 5466910 m N, had one assay of 0.525 gpt Au over 0.5 m from a quartz boudin, but the remaining results were discouraging (AFRI 2.56730).
