This barite occurrence is situated 800 metres upstream from the mouth of Barite Creek, immediately south of the Manson River and 4.5 kilometres northeast of the lower Gaffney Creek Bridge.
The Omineca Queen occurrence is found in both sides of the creek and consists of 3 to 7-metre thick sequences of layered barite found with graphitic slates and argillites of the Upper(?) Devonian to Lower Permian Big Creek Group (formerly the Cooper Ridge Group). Layering within the barite is produced by impurities such as quartz and organic matter. The barite is faulted and folded and strikes northwest with a vertical attitude. Although these barite bands appear to replace quartz-rich layers, they also indicate that the deposit may have formed as a sedimentary exhalative. Minor amounts of galena, sphalerite and tetrahedrite are known to exist.
A sample cut across 5 metres, plus 3 metres of exposed barite 120 metres east of a gully, yielded 63.15 per cent barium oxide (Geology, Exploration and Mining in British Columbia, page 374).
Diamond drilling is reported to have outlined four zones of barite mineralization, ranging from 54.09 to 63.15 per cent barium oxide, over widths of 4 to 8 metres (Assessment Report 30580).
The occurrence was discovered and staked in 1966. During 1970 through 1974, Falconbridge completed programs of soil sampling, trenching and three diamond drill holes. In 1992, Cominco completed a program of silt and soil sampling on the area as the Roe claims. In 2008, IBEX Resources completed a minor program rock and soil sampling.
