The Blue River Nickel occurrence is located near the headwaters of Nickel Creek about 124 kilometres north of the community of Dease Lake.

The upper section of Heazlewood Creek in the Cassiar Mountains has incised through partly serpentinized dunites and peridotites of the Blue River ultramafic body (Mississippian Slide Mountain Complex). The original showing consisted of nodular material, likely a nickel-iron alloy, in serpentinite. Medium to fine-grained heazlewoodite, a nickel sulphide, occurs locally with minor pentlandite. Most of the nickel in samples, averaging 0.24 per cent nickel, occurs in olivine (Property File - McDougall, J.J., 1954). Chrysotile fibre has not been reported from the occurrence.

In 2015, rock sampling (tag number A21563) in the area assayed 0.26 per cent nickel and 0.37 per cent chromium (Assessment Report 35654).

In 2015, Minfocus Exploration Corp. conducted limited prospecting and geological mapping which included the collection of specimens of the major hostrock types for multi-element assays (including nickel, platinum and palladium) and/or a limited petrographic study. The Myst Metals project area covers four mineral occurrences: Blue River Nickel (104P 001), Wolfe (104P 055), Anvil Chromite (104P 100), and Ice Lake (104O 018).
