Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The shaft area contains the A and B veins that are in reality one structure that has been traced 275 m and three offshoots, the C, D and E veins. The A/B vein strikes N75 deg. E to N80 deg.E and its dip, although variable is very steep toward the south. Veins C and D (carrying little gold) and vein E lie within the steep-dipping regional foliation that strikes east-west. The veins are hosted mainly in intermediate volcanic breccia and mafic lava, and gold values are absent where the main fracture zone crosses a 'turkey track' feldspar diorite porphyry dike east of the shaft. The main vein is typically 25 cm wide although in places it bulges to 1 m. The main vein consists of fractured quartz, containing appreciable amounts of pyrite and pyrrhotite, and small amounts of sphalerite, chalcopyrite and galena, plus high gold values. In places small stringers parallel the main vein and carry gold. DEPOSIT DESCRIPTION: This auriferous quartz vein has been tested by diamond drilling and underground development to a depth of 122 m. Four blocks of ore have been outlined, one of which is open to the east end at depth.
Apr 28, 2016 (Therese Pettigrew) - The gold mineralized zones lie within a regional shear structure, the Pipestone Bay-St Paul Deformation Zone, which trends approximately 105-110 degrees and crosses the center of the property (Archibald et al., 2016).

Mar 19, 2012 (K R Kettles) - MDI1 DATA: ESTIMATED RESERVES (1939): 10,900 TONS OF ORE @ 0.657 OPT AU OUTLINED IN 4 BLOCKS According to Gill (1939), 10,900 tons of ore with an average grade of 0.657 oz/ton (22.525 g/tonne) Au have been outlined in 4 blocks. The average thickness is 48.26 cm. It should be noted that block 4 appears to be open to the east and downwards, and block 3 appears open at depth (Lake Rowan Gold Mines Limited, circa 1939). 2007: Eight DDH targeted this area and underground workings, examples of assays returned: 11.58 g/t Au over 1.43 m, 40.8 g/t Au over 3.4 m.
Apr 28, 2016 (Therese Pettigrew) - In general, gold mineralization occurs as visible millimetre scale blebs in quartz veins, veinlets and stockworks. There appears to be a bias towards folded/sheared lithological contacts often involving felsic porphyries and/or iron formations. When units of differing competencies are deformed, voids can be created at or near their contacts and gold-bearing silica can later fill and seal these openings. Since the gold mineralization process appears late, any of the extrusive geological units can be a host for gold mineralization. Although the quartz veins host the gold, gold grades within these veins are often erratic and unpredictable. The best indicator is the presence of visible gold itself but even so the tendency for the gold to occur in nuggets can lead to misleading results from assays both positively and negatively. The wall rock adjacent to the quartz veins is generally barren. The Rowan Vein System has been the focus of the majority of exploration on the West Red Lake Project since the initial discovery of 4 sub-parallel narrow veins on surface at “Discovery Hill”. Since then these veins have been drifted upon from underground on 3-levels and extensively drilled. The Rowan Vein System consists of generally east-west trending narrow, sub-vertically dipping quartz veins near the shaft and the extension of these veins toward the east. The best gold grades often occur when course and visible native gold is present. This occurs within distinct 10 to 30 cm up to a metre of bluish to grey, glassy quartz veins/stringer zones. Rarely do these zones exceed 60 cm wide and broad zones of diffuse silicification have generally not been found. Trace to 1% pyrite and pyrrhotite is common within these veins/stringers. Less common but a better positive indicator of gold grade is the occurrence of sphalerite, galena, arsenopyrite and chalcopyrite. Generally total sulphides make up less than 2%. Gold mineralization in the Rowan mine is confined to a number of simple quartz veins less than 20 cm thick, which have been traced discontinuously for several hundred metres. A total of nine separate major vein systems have been recognized to date. These systems form en-echelon array trending 075-090 degrees and dissipate towards the west and with depth. Towards the east, the vein system appears to terminate abruptly. Within individual veins, the potential ore occurs in shoots where the veins thicken to a maximum known width of one metre. Such shoots typically measure 1m x 25m x 150m and plunge 45 degrees to the east (Archibald et al., 2016).
Dec 07, 2005 (K R Kettles) - The wallrocks are silicified, and immediately next to the veins are altered to carbonate and chlorite (Bishop, 1934).
