The IMPASSE (JC 9) occurrence is located on a small hill approximately 1.5 kilometres west northwest of the northwestern end of Jacobie Lake, 9 kilometres west of Mount Polley mine and 17.5 kilometres southwest of the village of Likely.

Regionally, the area is located within the central Quesnel Trough. The area is underlain by Upper Triassic to Lower Jurassic sedimentary and mafic to felsic volcanic rocks. This sequence has been intruded by small alkalic stocks of diorite to syenite compositions. This sedimentary and volcanic assemblage is correlative with the Nicola Group.

Locally, disseminated pyrite and chalcocite are hosted in strongly brecciated and carbonate-altered basalt with fragments containing intensely quartz-sericite-carbonate alteration. Native copper and malachite are also reported in the area. In 1984, a rock sample assayed 1.40 per cent copper (Assessment Report 13430). In 1991, a select grab sample (ST-011) assayed 1.06 per cent copper, while later the same year another sample (022) assayed greater than 1.0 per cent copper with 0.26 per cent zinc (Assessment Report 21584).

In 1984, Asamera Minerals completed a program of rock, silt and soil sampling, geological mapping and ground geophysical surveys on the area as the Impasse claim. In 1991, Pamicon Developments completed a program of geochemical sampling and geological mapping on the area as the Bud and JC claims.

In 2011, Eagle Peak Resources completed a program of geological mapping and rock and soil sampling followed by 600.1 metres of NQ diamond drilling in 3 holes in 2013. All holes cored layered units of massive grey and maroon basalt of the Nicola Group and thin bedded redbed sandstones and mudstones. Clay and brown carbonate alteration was common. No mineralization was noted during the drilling program (Assessment Report 34223).

In 2017 and 2018 Jedway Enterprises Ltd. conducted programs of geological mapping, air photo and geophysical interpretation on the area. Results indicated that Jurassic redbed copper mineralization which formed in Nicola Group Triassic volcanic rocks is cut by herringbone faults related to Cretaceous magnetism and hydrothermal mineralization and later the intersections of the herringbone faults were copper mineralized during hydrothermal activity in the Eocene.

The area surrounding Jacobie Lake was tenured to Eagle Plains Resources Ltd. who ran programs of geological mapping and till and rock sampling during 2022 through 2024. Rock samples returned values up to 0.145 per cent copper and 0.087 gram per tonne gold (Assessment Report 42845).
