Geology Comments

Jun 25, 2015 (R Degagne) - Geological mapping indicates that bedrock underlying the 4 patented Demers claims consists mainly of weakly met amorphosed (greenschist or lower metamorphic facies) east southeast striking, steeply south dipping, and south facing volcanic and clastic interflow sedimentary rocks of the (Archean) Kinojevis Group. The claims are a few hundred metres south of the Porcupine-Destor Fault Zone and straddle the western extension of a feature which Satterly termed the 'Consular-Ben Arch-McDermott Fault' and a laterally continuous subparallel structure located about 250 m north of it.

Lithology

Lithology Comments

Jun 25, 2015 (R Degagne) - The volcanics are pillowed flows and diabasic flows which face south. They are highly sheared near the fault in the south part of L11547 and carbonatized in the exposures adjacent to Teddy Bear Creek. Sediments are exposed on claim L11460 and in the extreme northwest corner of claim L11459. The metasedimentary band is offset by two cross-faults and is believed to be cut off by a strike fault trending N61ºE. In places, the sediments are carbonatized and all the exposure show minute fracturing. The fractures are filled with stringers of quartz or carbonate.

Mineralization

Mineralization Comments

Jun 25, 2015 (A Wilson) - A grab sample of mineralized material was collected by J. Satterly and assayed 0.01 oz/t Au. Two zones of mineralization have been defined by the Mission-Harker drilling. The best and most consistent gold results have been received from the Upper Zone, specifically as intersected in holes 6256-85-1 and -2 and holes 6256-86-7 and-8. All holes that intersected this zone returned wide sections of anomalous assays. For example the zone in hole-86-8, although lacking complete sample coverage, will average no less than 1.08 gm/tonne (0.032 oz/ton) across a drill width of 74.60 metres (244.75 feet). The Lower Zone also returned anomalous results, but only from the upper or A portion, where an apparently continuous zone of mineralization can be traced from section to section. The B portion of this Lower Zone, as tested to-date, shows a substantially lower degree of gold enrichment, when compared to the other two horizons. This would explain the lack of gold values in hole -86-4, which tested only the B portion of this Lower Zone. Assays from the upper zone returned values of 0.0256 oz/t Au over 28.61 ft including 0.0.63 oz/t Au over 6.10 ft. Assays from the lower zone returned assays up to 0.076 oz/t Au over 2.03 ft. The drilling was interpreted to have been successful in establishing the presence on the Demers claims of what was believed to be the extension of the Holt-McDermott auriferous zone, with representative core intersections through what was described to be Holt-McDermott type mineralization averaging 0.026, 0.039, 0.055, and 0.067 ounce of gold per ton across core lengths of 28.61, 53.21, 26.97, and 9.06 feet, respectively. In 1991, American Barrick Resources intersected a 10 ft section of core that assayed 0.26 oz/t Au.

Jun 25, 2015 (R Degagne) - Gold mineralization averaging from 0.01-0.06 ounce of gold per ton across many tens of feet is associated with variably pyritic, silicic, sericitic, hematitic, and carbonate bearing breccias which form laterally continuous zones which locally appear to crosscut stratigraphy. The highest gold tenors are reported to be associated with elevated pyrite contents and with breccia which appears to have been originally mafic in bulk composition. On the Demers claims, diamond drilling indicates the presence of at least 2 distinct subparallel horizons of Holt- McDermott type gold mineralization. Both horizons may contain anomalously elevated gold tenors, but the 'upper' (southern) horizon (spatially associated with Satterly's northern fault) is consistently more auriferous and was believed by Mission Harker Exploration geologists to represent the western extension of the Holt-McDermott Mine auriferous zone. The northern mineralized zone is spatially associated with the east striking 'Imperial Fault' of Satterly and probably represents the strike extension of Holt-McDermott-type mineralization which is known to occur on the old Imperial Reserve Gold Mines Ltd. claims, west of the Demers claims.
