Point Location Description: Adit in hillside on former claim AC 2120

Location Method: AMIS Site Visit

Access Description: This site was accessed by the Hawk Junction road. A vehicle is taken 11.4 km north of Hawk Junction along the side of the ACRrailway to a point where the road crossing has been taken out. (a left fork at 1.2 km and a right fork at 2.05 km north of Hawk Junction). On the other side of the tracks is the Goudreau/Forge Lake road, which is taken for 9.0km to the site. A few km west of Forge Lake the road splits; the south fork leads to the site. This site is located 200m southeast of Forge/Smith Lake and 460m south of the north tip of Forge Lake.

Geology Comments

Jul 01, 2013 (A Wilson) - The Forge Lake Deformation Zone extends from the west side of Forge Lake to the McVeigh Creek Fault. The north limit of the deformation zone is approximately the north contact of the main sedimentary unit and within 100 m of this contact towards the north. The south limit is marked by the supracrustal-granite contact. The rocks within the FLDZ are variously sheared from moderate to intense with the penetrative foliation being approximately parallel to the primary bedding where this is preserved.

Lithology

Lithology Comments

Feb 21, 2012 (A Wilson) - The Forge Lake property is underlain by intercalated north-dipping mafic flows, mafic and felsic tuffs with occasionally silty or siliceous horizons. These rocks strike between 90 and 110 degrees and dip north from 35 to 45 degrees. Two well developed oxide facies iron formations strike roughly east-west across the property. They are well bedded and are up to 1.5 m in width. Several late diabase dikes cut the stratigraphy. These dikes trend NW. Lamprophyre dikes are also prevalent in the area. The deposit is hosted within two sub-parallel quartz vein systems. These systems appear to be conformable to stratigraphy on a broad scale, but show low angle cross-cutting relationships on a detailed scale. The vein system consists of a swam of individual veins and veinlets ranging from a few millimetres to 3 m in width. The entire vein system varies in width from a few centimeters to 30m.

Mineralization

Mineralization Comments

Jul 01, 2013 (A Wilson) - Gold values from Amax chip sampling completed in 1979 returned values ranging from nil to 1.5 oz/t Au. Values up to 6.0 oz/t Au were recorded from grab samples collected from the mine dump. Three zones were identified in the sampling program. These zones gave weighted average assay values of: 0.064 oz/t Au over 6 feet; 0.093 oz/t Au over 13.5 feet; and 0.187 oz/t Au over 17.5 feet. Samples collected by Orequest in 1988 returned values up to 0.818 oz/t Au from grab samples. The main stripped area yielded values ranging from 0.1 oz/t Au to 0.597 oz/t Au. Assay values from the Hudson River drilling included: 16.5 g/t Au over 0.5 m in HR-FL-04; 4.10 g/t Au over 2.1 m in HR-FL-10 within 0.85 g/t Au over 14.7 m; 4.56 g/t Au over 3.3 m in HR-FL-12 within 1.81 g/t Au over 10.1 m; 4.35 g/t Au over 3.9 m in HR-FL-16 within 3.25 g/t Au over 12.6 m; 7.07 g/t Au over 5.5 m in HR-FL-20; 8.46 g/t Au over 1.0 m in HR-FL-22. The Forge Lake Property contains two zones of mineralization known as the Main Zone and the East Zone. They are located about 370 metres apart along and are both within the east-west trending Forge Lake Deformation Zone (FLDZ). Within the Main Zone the best gold assays come from major quartz veins located near the base of the deformation zone. Lower grade sections (Up to 0.89 g/t Au) are common and occur throughout the deformation zone but are not always continuous. For example, hole HR-FL-12 grades 4.56 g/t Au over 3.3 m within the major quartz vein and grades 1.81 g/t Au over 10.1 m within a thicker interval of the deformation zone that includes the major quartz vein. Within the East Zone the gold assays are more continuous throughout the quartz vein system (i.e. 3.4 g/t Au over 12.0 metres in hole HR-FL-16) but the thickness of these quartz veins can vary rapidly over a short distance. On average the quartz veins vary from 20 to 60cm in width. The hanging wall for both the main and east zones are felsic cherty tuffs with quartz eyes and are very silicified. Several contain 2 to 5% pyrite-chalcopyrite. The footwall rocks are porphyritic felsic tuff to mafic tuff with a chloritic matrix.
