The Hopeful quartzite deposit is 243 metres above Shuswap Lake, about 1828 metres up an old logging road that starts on the lakeshore 800 metres northeast of Quartzite Point.

A medium grained, white quartzite band, 9.1 to 12.2 metres thick, is interbedded with biotite hornblende gneiss within the Hadrynian? to Paleozoic Eagle Bay assemblage. The quartzite band is well exposed for 304 metres along a strike of 035 degrees on the surface of a small flat bench and in bluffs along its edge. It dips 10 degrees to the southeast. Although much of it is glassy to milky white, some is stained yellow to brown. Scattered patches of pyrite are present.

Workings on the deposit consist of one pit 1.8 by 0.9 metres, a cut on the edge of a bluff that is 4.5 by 3 by 2.4 metres, and three small blastholes. A mixed grab sample consisting of chips gathered from all of the workings analysed 97.28 per cent SiO2, 0.29 per cent Al2O3, 2.09 per cent CaO and 0.25 per cent Fe (total) (Minister of Mines Annual Report 1965, page 275).
