Lac Ménarik = 91 claims (46.76 km2) / Ménarik East = 68 claims (34.94 km2)

Two electric transmission lines run through claims

Near intersection between James Bay paved and Transtaiga gravel roads

LAC MÉNARIK AND MÉNARIK EAST PROPERTIES – REGIONAL GEOLOGY

Archean greenstone belt made up of volcano-sedimentary rocks / Yasinski Group basalt

Polymictic conglomerate along deformation corridor (Timiskaming-style) / early erosional unconformity? [blue unit]

Syenite-hosted and/or orogenic gold mineralization styles

Layered ultramafic-mafic igneous complex with Cr-PGE±Ni±Cu occurrences [purple unit]

LAC MÉNARIK PROPERTY– GOLD MINERALIZATION STYLES

Some of the best drilling intersections: 0.89 g/t Au over 68.25 m, 7.51 g/t Au over 1.41 m

Very high tenors in individual quartz veins (up to 500 g/t Au)

Mineralization and alteration more abundant where monzonite is fractured, brecciated and/or sheared

Feldspar-porphyritic

monzonite intrusion

Large-feldspar porphyritic monzonite intrusion spatially-associated to most gold occurrences; gold also in basalts, conglomerates, iron formations and gabbros (syenite-hosted model)

Most commonly in narrow quartz veins (stockwork), less commonly disseminated in host rock

Alteration consists in quartz, sericite, albite, calcite, dolomite, epidote, hematite; sulphides (pyrite, chalcopyrite, rare galena) in veins and host rock

Lake Ménarik sits on a major fault marking a sharp metamorphic contrast (greenschist to amphibolite facies)

LAC MÉNARIK PROPERTY – NEW 2017 GOLD SHOWINGS

Prospecting and geological mapping conducted by Harfang in 2016 and 2017

Discovery of additional high-tenor gold showings along a propable structure on the edge of the conglomerate unit (orogenic gold model)

Trenching yielded 1.04 g/t Au over 24.9 m

Geological setting located at intersection of several structural lineaments

IP survey completed over monzonite (25 linear km’s) with several anomalies

Joint Venture with Kenorland Minerals Ltd

Access by helicopter or floatplane

Great Whale Archean greenstone belt defined over 16 km x 8 km

Dominated by mafic volcanics; scarce terrigenous and orthochemical sedimentary rocks, felsic lavas, and ultramafic and felsic intrusions; major iron formations in the south

Generally greenschist facies, higher metamorphic grade locally

Geological mapping by the Federal and Québec governments before 1983

Exploration activities conducted in 1997, 1999 and 2000 by Virginia Gold Mines

Airborne Mag-EM and ground Mag-IP surveys, mapping and rock and till sampling done / no drillingyet

>30 gold showings mainly along the Esker and Cuesta trends in the western branch / some with high Zn-Pb-Cu-Ag tenors

Significant portion of the property covered by esker sediments / bedrock never investigated

LAC FAGNANT PROPERTY CHARACTERISTICS OF GOLD OCCURRENCES

Gold mineralization is found in sheared and altered basalts and in basalt-hosted quartz veins (orogenic gold model)

Alteration minerals include chlorite, actinolite, epidote, andalusite, K-feldspar, albite, sericite

Sulphides include pyrite, pyrrhotite, arsenopyrite, chalcopyrite, galena and sphalerite

Mesothermal gold-rich veins reach up to 47 g/t Au and polymetallic veins grade up to 29.2 g/t Au, 8.9% Zn, >1% Pb, 0.3% Cu, 70.2 g/t Ag in the western band

Low mag zone for the volcanic-dominatedportion of the belt / iron formations in areas with high mag signature

Western volcanic band more altered and deformed than eastern band / most probable explanation for abundance of gold in the former

Quaternary sediments (Esker) hide gold-bearing structures known to be associated with gold occurrences
