Location Method: Based on Assessment

Access Description: The Watershed Gold property can be accessed on Highway 144 from Sudbury and Timmins, Ontario and from the Sultan gravel Road which begins at the intersection of Highway 144 and Highway 560 (the so called “watershed”). Several dirt roads heading west from Highway 144 and dirt roads heading north from Sultan Road can be used to access the property. Some of the dirt roads are ploughed during the winter and can therefore be used year-round.

Lithology

Lithology Comments

Oct 16, 2015 (A Wilson) - The deposit is hosted within the Chester Granitoid Complex. It is comprised of massive to foliated, leucocratic to melanocratic, honblende diorite/gabbro to quartz diorite/gabbro and associated hornblende-plagioclase pegmatite dikes. The unit locally contains blue-opalescent quartz-eyes and magma mingling textures with the trondhjemite. Intrusive breccias occur locally. Massive to foliated, leucocratic, biotite (± amphibole) trondhjemite/tonalite to granodiorite, quartz-rich trondhjemite and feldspar poprphyritic trondhjemite. Typically contains distinctive blue-opalescenct quartz-eyes. Abundant sub-rounded to angular diorite, quartz diorite and trondhjemite inclusions exhibit frothy to pitted net-textures as well as both sharp and diffuse contacts with the host rock. The southern part of the Chester area is underlain by mafic intrusive rocks and the southwestern corner of the felsic intrusive rocks of the Chester Granitoid Complex . Felsic to intermediate intrusive rocks of the Smuts Pluton are located under the southwestern corner of the Chester area. Minor amounts of mafic and felsic volcanic rocks occur at the eastern border of the southern part of the Chester area. The northern part of the Chester area is located north of the Chester Granitoid Complex and is underlain by the northern limb of the Swayze syncline. A major NNW-trending fault, marked by Southcamp Bayand Mesomikenda Lake, offsets the rocks in the northern Chester area. East of the fault the Property is underlain by the felsic to mafic intrusive rocks of the Chester Granitoid Complex and the northern limb of the syncline, which is composed of the felsic volcanic rocks of the Chester group and mafic volcanic rocks of the October Lake Formation, similar to the rocks east of the fault. The northern limb of the syncline becomes narrower to the east. The mineralization at the Watershed Property consists of vein- and fracture-hosted visible gold and sulphides, dominantly pyrite and minor chalcopyrite and pyrrhotite. The veins are up to several 10s of centimeter wide and consist of quartz, sulfides and locally carbonate. The stringers consist of chlorite, hematite and sulfides and are very thin (one to several millimetres). Disseminated pyrite also occurs. Locally, neither veins nor disseminated sulfides are visible in drill core that carries significant gold. In these cases, very thin stringers likely host the gold.

Mineralization

Mineralization Comments

Oct 16, 2015 (A Wilson) - Grab samples collected on claim 3011820 in 2011-12 returned values of 0.19 g/t Au (sample 101B); 0.84 g/t Au (sample 102), 2.18 g/t Au (sample 103) and 1.21 g/t Au (sample 104). Eighteen samples were taken from this claim. Three grab samples were taken from the north boundary of this claim prior to the stripping. Samples Sant 103 and 104 had values greater than 1 g/t gold (2.18 and 1.21 g/t gold respectively) in a quartz diorite with minor chalcopyrite along fracture planes. Fifteen grab samples were taken to the southeast near trenches 1 and 2 prior to the washing and channel sampling. Three samples had values greater than 1 g/t Au. Sample Sant 105 and Sant 109, both taken from the west side of trench 2, had chalcopyrite associated with a quartz vein in a diorite/gabbro. Sample Sant 114 was the highest grab sample of this series from the trenches with a value of 3.09 g/t Au. It was a composite sample of a light coloured, ‘gritty looking’ rock (quartz diorite) taken from a flat area near the north end of trench 1 taken prior to the trench being washed. A series of channel cuts were later done in the vicinity of this grab sample- but the results were not duplicated. Sample 849949 located near the south end of the trench was the highest channel sample with a value of 4.422 g/t gold (trench 1). Sample 849816 located at the south end of the trench was the highest channel sample with a value of 6.181 g/t gold in a rusty, flat lying, ½ inch quartz vein within a medium grained gritty looking granodiorite. Two small channel cuts and a grab sample were made in the quartz vein and the host rock in an effort to determine the source of the gold- although the subsequent assays were low and inconclusive. Sample 849808, located about 10 meters northwest of sample 849816 was the 2nd highest channel sample from this trench and assayed 2.267 g/t gold. This sample was described as steeply dipping quartz vein in a dark gabbroic looking rock. (trench 2). Eight preliminary grab samples were taken from this trench, including two samples from the northern, filled in section. Three samples had values greater than 0.1 g/t- with the highest sample (16030) assaying at 2.012 g/t. This sample had 1% chalcopyrite in rusty fractures in a siliceous looking diorite. Thirty four channel samples were taken from this trench. Five samples had values greater than 0.1 g/t gold, with sample 849705 having the highest value of 0.708 g/t in a 1 cm pyrite vein in a grey granodiorite with blue quartz (trench 4). Twenty seven preliminary grab samples were taken from this trench. Ten of these samples had values greater than 0.1 g/t gold. Three of these 10 samples had values greater than 1 g/t gold, with sample 16042 having the highest value of 3.061 g/t gold; this sample was described in the field as being in “a fine grained, light gray granodiorite that contained < 2% mafics, 2-4% cp in 2-3 mm fractures and 1-2% py associated with a one cm mafic band” . Sixty seven channel samples were taken from trench five. Twelve of these samples assayed over 0.1 g/t gold and of these, four samples assayed greater than 1 g/t gold. The highest channel sample was sample 849660 which assayed 3.033 g/t over 0.65 m in a ‘sheared combination of fine grained, medium grey diorite with some ‘chloritic’ material- plus 5 cm quartz’. The 2nd highest channel sample, sample 849637, occurred about 10 meters west of 849660 and assayed 2.891 g/t in a fine to medium grained light greenish diorite (trench 5). Assays from the drilling program include: 62.216 g/t Au over 1.5 m, including 192g/t Au over 0.5 m in DDH SR-12-03; 32.866 g/t Au, including 45.86 g/t Au over 1.1 m in DDH SR-11-04; 31.7 g/t Au over 0.3 m in SR-12-02; 29.7 g/t Au over 1 m in DDH SR-11-04 and 24.3 g/t Au over 1 m in DDH SR-12-01. Additional results include 32.40 g/t Au over 0.6 m in SR-12-11; 14.5 g/t Au over0.8 m in SR-12-13 and 3.08 g/t Au over 1.0 m in SR-12-18.
