The Ridgeline occurrence is underlain by mafic and intermediate volcanic rock of the Middle Jurassic Salmon Creek Formation, Hazelton Group. A stock of Eocene quartz monzonite occurs about 2.5 kilometres south and contact with marine sedimentary and volcanic rock of the Upper Triassic Stuhini Group occurs about 1-kilometre northeast. Mineralized host rocks are tholeiitic mafic intrusive within mafic volcaniclastic rock.

In 2016, C.J. Greig & Associates Ltd., collected rock samples along a mountain ridge trending southeast to south from the Red Lightning prospect (104B 605) area. At least 28 rock samples were collected along the ridge for over 600 metres.

Strongly anomalous silver values, (greater than 20 grams per tonne) are in two areas; near the northern mineral prospects, GFJ (104B 233) and Red Lightning 104B 605), and about 400 metres to the south of the prospects, near the mountain peak. Strongly anomalous gold values, greater than 1.0 gram per tonne occur in the same areas, typically associated with moderately to strongly anomalous silver. Anomalous arsenic, (greater than 0.4 per cent), also is found in the same rock samples that contain anomalous gold and silver. Anomalous copper values, (greater than 0.2 per cent) observed in sample assays from the same two areas, however, not always from the same samples that have elevated silver, gold, arsenic. Two strongly anomalous zinc values (greater than 0.2 per cent) occur near the GFJ showing as well as the sample location at the southern point of the Ridgeline showing (sample CB-16-019), the plotted MINFILE location of Ridgeline.

One of the most notable samples (CB-16-30) graded 12.25 grams per tonne gold, 150 grams per tonne silver and 3.65 per cent copper (Assessment Report 36739). This grab was taken from abundant quartz vein float spread through sharp, platy talus. Quartz boulders to 60 centimetres were observed with fragments of sericitized rock to up 50 per cent. This area was thought to possibly be an upper/outer portion of polymetallic vein system.

Another notable sample (CB-16-33) was derived from a siderite-quartz sulphide-sulfo-salt vein. A chip across 40 centimetres of carbonate and quartz with 5 per cent arsenopyrite, 10 per cent pyrite and 3 per cent chalcopyrite graded 11.6 grams per tonne gold, 16.60 grams per tonne silver, 0.42 per cent copper and greater than 1 per cent arsenic (Assessment Report 36739). The host rock was described as a being strong black gossan with manganese staining.

Several other mineralized samples of interest are listed in Table 4 of Assessment Report 36739.

Work History

In 2016, C.J. Greig & Associates Ltd., on behalf of Eskay Mining Corp., conducted reconnaissance soil and stream sediment sampling in an area that has been mapped as Stuhini Group rocks, east of Ted Morris glacier on the southern part of the SIB property. Samplers collected 65 soil samples along a northwest-trending ridge located on the east side of the Ted Morris glacier. The soil line traversed an area mapped as Stuhini Group sedimentary and volcanic rocks. Samples were collected at 75 metres intervals along the line for a total line-length of about 4800 metre. Three stream sediment samples were also collected about 1 kilometre south of the soil line. A total of 126 rock samples were collected in a region encompassing about 35 square kilometres that surrounds the Ted Morris glacier. Areas sampled include Red Lightning (104B 605) and GFJ (104B 233) and areas farther south toward Ted Morris Glacier showing (104B 236).
