Geology Comments

Jul 08, 2015 (R Degagne) - The deposit is about 1600 m south of the east striking Porcupine-Destor Fault Zone. South of the Porcupine-Destor Fault Zone, the Kinojevis Group stratigraphy forms part of the north limb of the east striking and east plunging Blake River Synclinorium. Local bedrock stratigraphy strikes east northeast, dips steeply south, and faces south.

Lithology

Lithology Comments

Jul 08, 2015 (A Wilson) - Two narrow syenite dykes strike across the north part of the property, roughly east-west in orientation dipping steeply south. Thedykes are parallel to each other and are separated by a narrow 20 centimeter wide zone of meta-sediments. The dykes themselves are roughly one meter wide and may be traced for up to 300 meters. To the east and west, only one dyke was found but is probably a continuation of the same Intrusive. The dykes are purple to dark red in colour,fine grained with small phenocrysts of feldspar throughout, they havepreviously been termed a feldspar porphyry. Three types of sediments were found on the property. The first type is a carbonate-looking rock found on the extreme north part of the Demers property. They vary from pyritic cherts to a dark purple rock closely resembling a carbonate, they do not however, react with acid. Some argillic sediments were found interbedded with the cherts. In this area, the sedimentary/volcanic contact is characterized by a narrow zone of black, possibly tuffaceous volcanics containing up to 0.5% sulphide stringers. The bedding of the sediments varies from an east-west strike dipping steeply south to a northeast-southwest strike indicating that the sediments have probably been drag folded. The second sedimentary type rock is a poorly exposed schistose rock found in contact with the syenite dykes. The schistosity mayrepresent primary bedding striking east-west dipping vertically to steeply south. This zone of sediments may be traced only 150 meters instrike length. The third type of sediment is a dark purple silicified, partially brecciated rock containing up to 15% sulphide, normally finely disseminated throughout. The sulphides appear as bands within the rock and may conform to the original bedding of the rock.

Jul 08, 2015 (R Degagne) - Geological mapping indicates that the deposit area is underlain mainly by weakly metamorphosed (greenschist orlower metamorphic facies) volcanic and interflow tuffaceous, clastic and/or tuffaceous rocks of the (Archean) Kinojevis Group. The deposit is about 1,600 m south of the east striking Porcupine-Destor Fault Zone. South of the Porcupine-Destor Fault Zone, the Kinojevis Group stratigraphy forms part of the north limb of the east striking and east plunging Blake River Synclinorium. Intrusive rocks in the area include narrow syenite dikes.

Mineralization

Mineralization Comments

Jul 08, 2015 (A Wilson) - The drill program completed by Imperial Reserve Mines in 1942 intersected 2 distinct mineralized zones, both of which averaged approximately 0.06 oz/t Au. Amax Resources found sulphide mineralization in the Demers sediments,sediments adjacent to the syenite dykes and in the silicified brecciated sediments further to the west. The syenite dykes themselves do not carry any sulphides. The Demers sediments gave no gold values as did the volcanics in contact with the sediments. Three grab samples from the syenite/sedimentary contact zone (lines 29+60 W, 4+30 N) gave two values of; 0.01 oz/ton Au and 0.03 oz/ton Au. These samples were taken from Canamax trenches over the contact zone. A 1.00 m sample from syenite in DDH MC85-242 assayed 5.14 g/t Au. A 0.88 m sample from DDH85-243 assayed 1.54 g/t Au in a silicified zone

Jul 08, 2015 (R Degagne) - At least two areas on ground formerly held by Imperial Reserve Mines Ltd. are known to be host to anomalously elevated gold tenors. The first area is within and adjacent to claims 430918-920, a restaking of Imperial Reserve Mines claims 13404-406. Here, diamond drilling by Amax Minerals Exploration and Barrick Resources Corp. has intersected significant (see Reserves, above) Holt-McDermott type gold mineralization (gold associated with pyrite within variably brecciated and laterally continuous domains of quartz-hematite-sericite-dolomite-albite) within the hanging wall (southern) side of the east striking and steeply south dipping Imperial Fault. A syenite dike is reported to intrude the auriferous zone. Diamond drilling by Mission Harker Exploration Ltd. may have intersected the eastern extension of this Imperial Fault associated auriferous mineralization on Demers claim 11547. On old Imperial Reserve Mines claim 27600 (located about 2,000 m southwest of the Imperial Fault mineralization), grab samples from bedrock exposures of what has been variously described to be pyritic sediments and/or brecciated pyritic and pink (albitic?) quartz zones have averaged 0.01-0.98 ounce of gold per ton.
