The Vano showings were first examined in 1989 by Baymag Mines. They are between 75 and 200 metres north of the Cross River forestry road at "mile 14.5" (just past a major creek).
The rocks hosting mineralization are dolomitized reef platformal carbonates of the Middle Cambrian Cathedral Formation. Mineralization consists of magnesite and magnesitic dolomite. It is coarse (greater than 10 millimetres) to sparry, buff to white, and forms massive pods or lenses. Mineralization is scattered within the dolomite package.
Diamond drilling results indicated MgO contents ranging from 40 to 93 per cent in calcined samples in 10 shallow holes (less than 30 metres) over a 0.75 hectare area (3 units).
Showings in the area extend across the Cross River to the south and to the Miller Pass area. They are all part of the same mineralized system in the Mitchell River-Cross River area. Magnesite mineralization at the Vano showings is similar to that of the Baymag mine (082JNW001) to the north.
