The Royal property is situated between Royal and Standard creeks, just east of their confluence with Cadwallader Creek, on the west facing slopes of Royal Peak. In this part of the Coast Crystalline belt, splays and cross faults of the Bralorne fault system are spatially related to numerous mineral occurrences in the Bridge River mining camp.

The Royal prospect is underlain by a sequence of quartzites, argillites, quartz-biotite schists and minor volcanics of the Mississippian to Jurassic Bridge River Complex (Group). A pod of Permian Bralorne Igneous Complex hornblende diorite has been tectonically emplaced into Bridge River metasediments in the vicinity of the Royal adit, driven in the early 1930's. A northwest trending, structurally emplaced sliver of serpentinized ultramafics of the President Ultramafics (correlative with the Permian and older Shulaps Ultramafic Complex) is located just west of the diorite.

The Royal zone is an oval area of hydrothermal alteration, 1 kilometre in diameter, with numerous quartz veins up to 1.5 metres wide hosted in hornblende diorite and surrounding metasediments. Two stages of quartz veins are variably mineralized with pyrite, molybdenite, scheelite, chalcopyrite and sphalerite. Host rocks are silicified. Diamond drilling in 1986 revealed anomalously high values for molybdenum, copper, zinc, silver, nickel and arsenic, erratically distributed throughout drill hole 86-15. The presence of a molybdenum porphyry system, with peripheral or telescoped lead-zinc-precious metal mineralization is suggested. Diamond drill results have been disappointing, with a best assay to date of 0.06 gram per tonne gold (Assessment Report 16725). A sample taken in 1980 assayed 2.58 grams per tonne silver, 0.08 gram per tonne gold and 0.25 per cent tungsten (Assessment Report 8878).

Work History

During 1932 through 1934, Cadwallader Gold Mines conducted small scale programs of hydraulic placer mining, trenching and developed a short adit (Royal adit) on the veins.

During 1980 through 1982, Hillside Energy explored the area and completed programs of soil sampling. In 1984, Trans Atlantic Resources Inc. acquired the property and during 1984 through 1986, in conjunction with A & M Exploration, completed program of geochemical sampling, geophysical surveys and two diamond drill holes. In 1987, Trans Atlantic and Armeno Resources Inc. completed a further program of geochemical sampling, ground electromagnetic and magnetic surveys and two diamond drill holes.

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.
