The Princess property consists of the Victoria, Princess, Prince and Monarch Reverted Crown grants (Lots 14284 to 14287 respectively).

Magnesite is exposed at the base and again on the north wall of an irregular cirque at the headwaters of Hellroaring Creek. Magnesite occurs in a bed 3 to 6 metres thick underlain by white quartzite of the Lower Cambrian upper Cranbrook Formation and is overlain by thin bedded, green siliceous argillites of the Lower Cambrian Eager Formation. The stratigraphy is folded into a tight north-trending (020 degrees) syncline with a northerly plunge. There is considerable shearing and fracturing along the trend parallel to the fold axis.

In the floor of the cirque, the bed of magnesite is exposed over a strike length of 131 metres and is exposed again in the north wall of the cirque for 213.4 metres horizontally and a vertical exposure of 122 metres to the top of the ridge. A small opencut exposed a badly sheared and fractured magnesite horizon containing abundant pods and veinlets of quartz. The magnesite varies from pearly grey to buff, is very coarse grained and has a brown weathered surface.

Sample A is a chip sample collected by McCammon (Minister of Mines Annual Report 1964, page 193) across a 10-metre face from the opencut. Sample B is a sample of unknown character reported by Cairnes (1932). All oxides in per cent.
