Point Location Description: Located from map in AFRI 52F05SW0043

Location Method: Conversion from MDI

Access Description: Access to the property can be gained by travelling east from Highway 71 along the Cameron Lake Road, located approx. 10 km south of the town of Sioux Narrows. After travelling about 15 km along the Cameron Lake Road, a 3 to 4 km boat ride to Caviar Lake via Flint Lake, then boating north to Dogpaw Rapids and then south into Dogpaw Lake, or by utilizing a well-maintained 200-metre portage between the southernmost parts of Caviar and Dogpaw Lakes. Alternatively, a boat can be launched from the Whitefish Bay Indian Reserve on the northwest side of Dogpaw Lake.

Exploration History

Geology Comments

Aug 25, 2017 (Therese Pettigrew) - The Dogpaw Lake Property occurs near the junction of two regional faults, the Pipestone-Cameron Deformation Zone (PCDZ) and the Wabigoon Fault, each of which is traceable for hundreds of kilometres along strike and is spatially associated with several significant gold occurrences. The PCDZ trends in a northwest direction across the southern portion of the property, while the Wabigoon Fault cuts stratigraphy in a north-northeasterly direction less than five kilometres east of the property. The PCDZ is a major zone of shearing up to 500-600 m wide, defined by strongly schistose rocks and extensive carbonate, sericite, and chlorite alteration (AFRI 52F05SW2003).

Lithology

Lithology Comments

May 16, 2017 (C Ravnaas) - This occurrence lies along a sheared contact between felsic to intermediate pyroclastics and mafic volcanics. Where exposed, the shear displays a width up to 8 meters, strikes 1650 and dips 780 south. The felsic pyroclastics display strong sericite, silica, carbonate and chlorite alteration with local minor quartz flooding and trace pyrite. The mafic volcanics near the shear are chlorite, silica altered with mm-scale quartz stringers, local quartz flooding, 1% pyrite and local traces of chalcopyrite. (Kenora AF 52F05SW, MMMM-2, 2.27990, Cunniah Lake Inc, pg.24).

Aug 25, 2017 (Therese Pettigrew) - The surface geology consists of metabasalt with an interbedded 300 foot (90 m) thick unit of intermediate lapallistone and tuff-breccia. The rocks in the western part of the claim group are intensely sheared and carbonatized in places and are part of the major shear zone that extends through Dogpaw Lake. A north-northwest-trending diabase dyke also occurs in the area (Davies and Morin 1976). The property is underlain by mafic metavolcanic rocks belonging to the middle series of the Rowan Lake Group, which mainly occur as fine- to coarse-grained, locally pillowed flows and lesser tuffaceous units. Vesicular flow tops and flow breccias occur on the southwestern portion of the peninsula directly south of the Gauthier Occurrence (AFRI 52F05SW2003).

Mineralization

Mineralization Comments

May 16, 2017 (C Ravnaas) - GRADE: ASSAYS FROM TRACE TO 0.15 OPT AU - DDH ASSAY: 0.85 OPT ACROSS 1.5 M. Twenty-two grab samples were collected. These samples returned values ranging from 16 ppb to 127,773 ppb Au, with high grade gold values seemingly confined to quartz veining. Most of the quartz veining had been previously removed, but where exposed appears to be10 to 50 cm wide (Kenora AF 52F05SW, MMMM-2, 2.27990, Cunniah Lake Inc.)

Aug 25, 2017 (Therese Pettigrew) - Visible gold in quartz vein 2.5 to 4 ft wide x 150 ft long (Beard and Garratt, 1984). The main showing on claim K11109 consists of discontinuous quartz veins along a well-marked shear which seemed to lie approximately along the contact of basic lavas (to the south) and acidic lavas. The strike is roughly south 50 degrees east and the dip steeply to the north. Quartz, in widths up to 3 feet, is mineralized with small amounts of pyrite and the enclosing light-coloured schist also contains some pyrite. Grab samples of quartz have contained gold up to 0.26 opt. Assays from main zone intersected by the 3 DDH drilled by Gauthier ranged from 0.65-0.85 opt Au. Assays from channel samples over the main zone ranged from 0.09-0.77 opt Au. Gauthier reported grab sample assays up to 2.4 opt Au (Davies and More, 1976). Nuinsco’s 1986 DDH NF-3 returned one gold assay of 0.62 opt Au from 177-178.4 ft (AFRI 52F05SW0043). Sulphide mineralization on the property consists of disseminated pyrite and lesser chalcopyrite, typically in associate with quartz-carbonate veins and altered shear zones. Disseminated pyrite content in narrow zones within the wallrock adjacent to some of these veins is as high as 15%. The Gauthier Occurrence occurs along a northwest trending shear zone (Gauthier Shear Zone), interpreted from the magnetic data to extend in a southeast direction across the entire property. Gold mineralization appears to be concentrated within discrete sericite-ankerite shears and deformed quartz-ankerite veins within a 30 metre wide zone of silicification along the southern boundary of the Gauthier Shear Zone. This zone of silicification was traced for 250 m along strike. The host lithologies consist of mafic volcanic rocks and lesser quartz-feldspar crystal tuffs. Grab samples from the 1997 program only returned assays of up to 1.46 g/t Au (AFRI 52F05SW2003). During the 2004 sampling program by Cunniah Lake Inc., 22 grab samples were collected and returned values ranging from 16 to 127,773 ppb Au (AFRI 52F05SE2006).
