The Bend North Road Zone is 2.85 kilometres northwest of the Bend 1 Canyon Zone prospect (083D 001), and about 109 kilometres south-southeast of Valemount. It is one of several stratiform exhalative massive sulphide showings occurring along a west-northwest trending zone, almost 330 metres long and approximately 60 metres wide.

A sequence of quartzites, carbonates and pelites from the Hadrynian Miette Group through the Lower Cambrian Gog Group through to the Middle Cambrian Chancellor Group comprises the rocks of the Southern Park Ranges in this area. For a more comprehensive description of the regional geology refer to the Bend 1 Canyon Zone prospect (083D 001).

Stratiform mineralization at the Bend North Road Zone consists of a lower zone, and an upper zone on a west-facing dip slope (Assessment Report 9994). Both zones occur in the Tsar Creek Formation of the Middle Cambrian Chancellor Group. Many layers are tightly folded with axial planes striking southeast and dipping steeply southwest.

Fine-grained sphalerite, galena, pyrite and pyrrhotite in manganiferous chocolate weathering dolomite, comprise mineralization at the upper zone. Massive chlorite is developed at the base and massive sulphide blebs are associated with silicification in tension cracks. Material sampled from this zone assayed 3 per cent zinc and 1 per cent lead (Assessment Report 9994). Surface exposure outlines a tabular body 300 by 150 by 2 metres. This mineralization may be correlative with that of the Bend 1 Canyon Zone.

The lower zone mineralization consists of disseminated sphalerite, galena, pyrite and pyrrhotite in silicified manganiferous dolomite, 6 metres thick. Sampled rock from this zone yielded values of 6 per cent zinc, 2 per cent lead and 27 grams per tonne silver (Assessment Report 9994). Mineralization is overlain by a garnet mica schist and underlain by a thin silicified quartzite.

In 1985, two holes were drilled immediately southwest of the Bend North Road Zone, totalling 211.85 metres. Drillhole MGM-1 intersected quartzite with occasional high silica intervals with secondary interstitial carbonate and infrequent thin chocolate brown dolomitic horizons. The hole was essentially barren except for trace amounts of galena in fracture fillings. A sample taken at 35.08 metres assayed 0.27 gram per tonne gold, 2.0 grams per tonne silver, 0.0158 per cent lead and 0.15 per cent zinc (Assessment Report 15251). Drillhole MGM-2 intersected predominantly garnet muscovite pelite, increasing in coarseness and staurolite content with depth. Trace amounts of galena were noted in a white quartzite layer and within a dolomitic breccia (Assessment Report 15251).

In 2015, soil and rock sampling was conducted on the Cummins River property on behalf of Tsar Creek Holdings Ltd. The Cummins River claims covers the North Road showing (083D 002, this description) and Canyon/Bend (083D 001) showings. The ground work included the collection of 430 soil samples. Also in 2015, an airborne geophysical survey was completed on behalf of Tsar Creek Holdings Ltd. A total of 623 line kilometres of helicopter-borne electromagnetic (VTEM) geophysical data were acquired. See Bend 1 Canyon Zone (083D 001) for a detailed work history.
