The Ymir Belle showing is located 10 kilometres northeast of Ymir, in between the Foghorn (082FSW078) and Wilcox (082FSW077) mines. Workings consist of small open cuts and pits and a shaft 44 metres deep.

The area is underlain by granodiorite of the Late to Middle Jurassic Nelson Intrusions (Nelson batholith) which contains roof pendants of mica schist and quartzite of the Lower Jurassic Ymir Group. Quartz veins occur in shear zones and as fissure fillings which trend east to northeast and are crosscut by lamprophyre dykes.

The showing consists of three veins, two of which may be strike extensions of a single vein.

These two veins strike about east and dip 60 to 70 degrees north. The veins are parallel and have an average width of 0.60 to 0.90 metre, but may be up to 1.5 metres in width. The gangue is quartz and decomposed granite with pyrite, galena and sphalerite. Sampling indicates local grades of 8 to 10 grams gold. A chip sample across 1 metre of the New Victor vein, including 0.20 metre of quartz-pyrite vein material, assayed 5.0 grams per tonne gold and 5.2 grams per tonne silver (Assessment Report 17985)

The third vein strikes north, is about 0.40 to 0.45 metre wide and is reported to contain up to 30 grams per tonne gold locally. This vein, the Ymir Belle vein, is exposed in a shaft immediately north of the New Victor Crown Grant. The best assay from a sampling program in 1988 was from a chip sample across 0.3 metres of a small pit 15 metres west of the shaft. This chip sample assayed 8.9 grams per tonne gold and 1.7 grams per tonne silver (Assessment Report 17985).
