The SR-ESK-51 occurrence area is mapped as andesitic volcanics of the Middle Jurassic Salmon River Formation, Hazelton Group (Assessment Report 30131). A stock of Eocene quartz monzonite occurs to the immediate west and contact with marine sedimentary and volcanic rock of the Upper Triassic Stuhini Group occurs about 2 kilometres east.

Sample SR-ESK-2016-051 was taken from a 2-centimetre-wide pyritic massive sulfide vein having a strong halo of disseminated pyrite. The vein attitude was 225 degrees strike with a 51 degrees northwest dip, cross cutting the foliation of the meta sedimentary host rock. Abundant veins of the same mineralogy were reported visible at this location. The sample assayed 0.126 per cent copper and 0.0078 per cent molybdenum (Assessment Report 35739).

Sample SR-ESK-2016-047 was vuggy, coarse-grained quartz float material containing greater than 10 per cent molybdenite. The host rock was described as a meta-volcanic rock/gneissic. The sample assayed 0.76 per cent molybdenum and 0.036 per cent copper (Assessment Report 35739).

Sample CB-16-016 was taken from a 25-centimetre-wide quartz vein with minor pyrite. The vein had a 220-degree strike and 85-degree dip. Stockwork pyrite veinlets common in host hornfelsed tuff at this location. The sample assayed 0.184 copper and 0.008 per cent tungsten.

Sample CB-16—017 was taken from a 30-centimetre-wide pyrrhotite-chalcopyrite bearing angular quartz boulder. The sample was described as "high temperature quartz with 20 per cent pyrhottite and 3 per cent chalcopyrite". The material assayed 0.367 per cent copper and 0.012 per cent tungsten (Assessment Report 35739). It was reported as the first occurrence of this type of mineralization coming down slope from the glacier toe, although there were several "barren-looking" high temperature quartz veins and many pyrite veinlets.

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 metres. 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).

In 2020, Eskay Mining Corp. completed a program of prospecting, rock sampling, ground and airborne geophysical surveys and 4335 metres of diamond drilling in 20 holes on the area as part of the Sib-Corey-North Mitchell property. The geophysical surveys consisted of a 911.7 line-kilometre airborne electromagnetic survey, a 55.85 line-kilometre induced polarization survey and a 43.19 line-kilometre magnetotelluric survey. Drilling was performed on the TV (MINFILE 104B 385) and Jeff (MINFILE 104B 525) occurrences.
