A 56-metre wide lens of grey to white, fine to coarse-grained limestone strikes northwest for 274 metres along a hillside 300 metres north of Piebiter Creek, 46 kilometres north-northeast of Pemberton. The lens dips steeply northwest. The limestone is hosted in basalt, andesite, tuff and breccia of the Mississippian to Jurassic Bridge River Complex.

A narrow zone of scheelite-chalcopyrite bearing skarn is developed along the margin of the lens. A chip sample taken across a 22.3 metre section of limestone analyzed 55.00 per cent CaO, 0.25 per cent MgO, 1.10 per cent insolubles and 0.04 per cent R2O3 (Minister of Mines Annual Report 1948, page 102, Sample 935K).

The occurrence was first reported in the 1948 B.C. Minister of Mines Report.

In 1979, Hat Creek Energy Corp. examined the area. In 1987, Trans Atlantic Resources Inc. and Armeno Resources Inc. completed a program of geochemical sampling and ground electromagnetic and magnetic surveys of the skarn zones.

In 2006, Covenant Resources Ltd. examined the area as the Piebiter property. In 2007 and 2008, airborne ZTEM surveys were completed on the area. In 2009, a MMI soil sampling program was completed. In 2011, Worthington Resources Ltd. completed a 408.5 line-kilometre airborne ZTEM survey on the area as the Royalle property.
