Point Location Description: cluster of drill holes on map in 20000007391

Location Method: Based on Assessment

Access Description: Access to the property is by secondary Highway 802 which leads south from Highway 11, two kilometres west of Kashabowie and links to a major forestry road. The northern claims straddle these two roads. The southern claims are accessed by the major logging road. Several abandoned logging roads traverse the property and can be easily travelled by ATV.

Lithology

Lithology Comments

Jan 20, 2014 (A Wilson) - The geology in the area is best described as underlain by mafic and subordinate felsic metavolcanic rocks with minor interflow metasedimentary rocks and metadiabase, intruded by smaller bodies of feldspar porphyry and quartz – feldspar porphyry. Other intrusions include gabbro and quartz syenite. Interbedded metasedimentary rocks are present east and south of the area. The most prominent geological feature on the area is a large - 5 by 2 km - rhyolite dome complex situated in the western portion of the property (Figure 4). This complex which trends WSW to ENE, is an antiform and interpretively plunges doubly to the ENE and WSW. At the western boundary of the property the rhyolite complex is cored by felsic to mafic intrusive rocks. The rhyolite dome/antiform is flanked both to the NW and SE mainly by intermediate volcanic rocks and by lesser amounts of felsic fragmental volcanic rocks and is capped by mafic pillowed flows. To the northeast the dome evolves into a complex of interfingering mafic to felsic fragmental volcanic rocks and a smaller felsic dome occurs in the Mud Lake area near highway 11, 3km east of Kashabowie. A small, but economically important, component of volcanic strata along the southern flank is the exhalite horizon (chert, tuffite) that hosts VMS-style mineralization in the area. East to Northeast trending clastic metasedimentary rocks of the Quetico sub-province are present on the northern margins of the claims. These rocks are mainly composed of greywacke and siltstones. Locally the contact with the Shebandowan metavolcanic rocks has been postulated to be a fault. The Quetico sediments are considered to overlie the volcanics of the Shebandowan belt. Within the claim group several small and one large sill-like body of gabbro are present, the largest has been traced over 10km from Kashabowie Lake to southeast of Iris Lake. Several sills and dykes of quartz feldspar porphyry also occur.

Mineralization

Mineralization Comments

Jan 20, 2014 (A Wilson) - At Vanguard East, rocks are exposed over 140 by 50 meter area in a WSW direction and are similar to Vanguard West. Several sub-parallel bands and lenses of 1 to 10 metres wide chert-carbonate are enclosed in altered mafic metavolcanic rocks. A 20 by 2-m lens of massive sulphide is hosted within the chert horizon. In the northern and western part of the exposure up to 25 m of fragmental intermediate to felsic metavolcanic rocks are exposed. At both Vanguard East and West, intense alteration is developed on both sides of the chert horizon. The alteration minerals in order of abundance are: Fe/Mg carbonate, chlorite, silica in silicified and chloritized mafic metavolcanics and quartz+carbonate±sericite schist. Pyrite is disseminated in both footwalls and hanging walls. Systematic whole rock analysis of Noranda diamond drill core showed that broad zones of alteration at Vanguard East and West are depleted in sodium and calcium and enriched in silica, iron, magnesium, copper, zinc, silver and gold. This alteration suite is manifested over 150 meters of core in hole S-90-1, drilled at Vanguard East. The interpreted zone is steeply dipping to the southeast and consists of massive sulphides lenses with chalcopyrite-quartz stringer alteration zones. All 4 holes intercepted VMS-style alteration, mostly in the form of chalcopyrite within a zone of quartz stringers, with 2 of the 4 holes intercepting massive sulphides. Holes VE-12-02 and VE-12-04 intercepted the highest concentration of mineralization, with Cu values as high as 22,209ppm, or 2.2% Cu with 7,402ppm Zn in VE-12-04, and Zn values as high as 32,584ppm in VE-12-02. The return of these values presents a viable economic potential for a copper-zinc deposit over Vanguard, however mineralization controls still need to be assessed and interpreted in order to extend strike and depth of the known mineralization.

May 19, 2016 (Therese Pettigrew) - The average grade of the 9.75 m massive sulphide phase of the hole VE02-1 was 1.26 g/t Au, 13 g/t Ag, 2.03% Cu and 2.13% Zn. The average grade of the 6.6 m massive sulphide phase of the hole VE02-2 was 2.14 g/t Au, 43.4 g/t Ag, 2.73% Cu and 3.49% Zn. In 2004, hole VE04-5 was drilled to intersect the zone previously intersected in hole VE02-1 and 2. Hole VE04-5 yielded 4.15 m of 6.39% Zn and 1.89% Cu with 28.31 g/t Ag and 0.88 g/t Au in massive sulphides. Hole VE04-3 located 15 m west of VE02-2 and down plunge, hit up to 2.0% Cu, 14.8 g/t Ag and 0.58 g/t Au and a wide silica zone, which is part of the regional chert horizon that marks the occurrence of VMS mineralization (http://www.whitemetalres.com/vanguard.html).

Alteration Comments

May 19, 2016 (Therese Pettigrew) - At both Vanguard East and West, intense alteration is developed on both sides of the chert horizon. The alteration minerals in order of abundance are: Fe/Mg carbonate, chlorite, silica in silicified and chloritized mafic metavolcanics and quartz+carbonate±sericite schist. Pyrite is disseminated in both footwalls and hanging walls. Systematic whole rock analysis of Noranda diamond drill core showed that broad zones of alteration at Vanguard East and West are depleted in sodium and calcium and enriched in silica, iron, magnesium, copper, zinc, silver and gold. This alteration suite is manifested over 150 meters of core in hole S-90-1, drilled at Vanguard East. Such depletion/enrichment patterns are widespread in VMS systems and associated principally with wall rock alteration around hydrothermal vents (AFRI 20000007391).
