The Miller Pass showings are new in the Cross River area. They extend across the end of a ridge between the Cross River and a creek flowing north out of Miller Pass (informally Miller Pass Creek). Access is by logging road, turning off west from "16 mile" on the Cross River forestry road.

The showings are hosted by carbonates of the Middle Cambrian Cathedral Formation. Locally the host carbonates are dolomitized (diagenetic) and brecciated. Magnesite and magnesitic dolomite form massive zones in the dolomite. Replacement textures, including fenestrae, overprinting and breccia in-filling, are common. Significantly, the showings are within 1000 metres of the Cathedral escarpment similar to the location of the Baymag mine (082JNW001). Magnesite and magnesitic dolomite is often coarse (greater than 10 millimetres) and sparry, white to buff in colour, and massive or forming bladed crystals.

Preliminary analysis of apparent high grade material yields a CaO/MgO ratio of 0.33 and a calcined MgO content of 74 per cent; work was done by the Geological Survey Branch, Ministry of Energy, Mines and Petroleum Resources.

The showings extend down the ridge both to Miller Pass Creek and Cross River. The Vano (082JNW013) showings are north across the Cross River and are part of the same mineralizing system.
