The CB-9 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.

In 2016, several samples were taken on behalf of Eskay Mining Corp in a glaciated area with little rock exposure.

In sample CB-16-009, molybdenite occurs as a 1-centimetre halo in hornfels around a 2-centimetre massive pyrite vein, in outcrop. Many pyrite veins in outcrop are reported to occur in this vicinity. Sample was also reported to difficult due to glacially rounded outcrop, which is very gossanous, with yellowish sericitic weathering and next to glacier edge. Sample CB-16-009 assayed 1.3 grams per tonne silver, 0.181 per cent copper, and 0.594 per cent molybdenum (Assessment Report 35739).

Sample CB-16-006 was taken about 100 metres to the south of CB-16-009. A 0.5 metre chip sample with 3 centimetres massive pyrite vein in a centre vein was hosted in silicified hornfels, next to gossanous weathering pyritic hornfels. From 1 per cent to locally 15 per cent molybdenite occurs in in halo around pyrite vein up to 25 centimetres on either side of vein this increases to a maximum molybdenum concentration adjacent the pyrite. Stronger silicification and very dark coloration of hornfels is associated with molybdenum mineralization, but is also deeply weathered and sericitic in parts, which also contains abundant molybdenite. Several other pyrite veins were examined in area, but no other molydenum was found. Sample CB-16-006 assayed 0.392 per cent molybdenum (Assessment Report 35739).

Several rock samples were taken about 100 metres west of CB-16-06 ranging from 0.084 per cent copper to 0.378 per cent copper (Assessment Report 35739). Two samples were taken from talus, one from outcrop. Samples were taken from gneissic sedimentary host rocks with abundant manganese oxides and pyrite.

About 250 metres east of CB-16-009 are two mineralized outcrop samples. The best is SR-ESK-033 which assayed 5.8 grams per tonne silver, 0.394 per cent copper, 0.149 per cent tungsten and 24.5 per cent iron (Assessment Report 35739).

Going north from SR-ESK-033 another 250 or so metres are several more mineralized samples of angular float (as follows) with possible nearby sources.

A very large angular boulder was sampled (CB-16-010) and resulted in a grade of 0.151 per cent copper, 0.024 per cent molybdenum, 0.48 per cent tungsten and 21.9 per cent iron (Assessment Report 35739).

Massive pyrhottite-chalcopyrite plus/minus pyrite angular vein float is common in area of talus, sometimes containing a little molybdenite. Veins from 2 centimetres to 12 centimetres are common but examples with more than just a little molybdenum are not. CB-16-041 assayed 0.208 per cent molybdenum and 0.0338 per cent copper (Assessment Report 35739).

Nearby sample CB-16-040 was derived from an angular boulder consisting of a quartz sulphide vein which assayed 1.2 grams per tonne silver, 0.250 per cent copper and 0.022 per cent molybdenum (Assessment Report 35739). The 20-centimetre angular boulder contained 5 per cent disseminated molybdenite, 6 per cent pyrite (mixed with some pyrrhotite) and 1 per cent chalcopyrite. This sample was found at the toe of a glacier.

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.
