The Bar-Barriere occurrence is located on the east side of Harper Creek, approximately 7.5 kilometres southeast of Dunn Peak and at an elevation of approximately 1020 metres.
The area is underlain by quartz-monzonite and granodiorite of the Cretaceous Baldy Batholith. Later-phase aplite dikes and quartz veins are common throughout the rock. Locally, the quartz-monzonite is fractured, brecciated and altered.
Locally, a 150- by 100-metre area, referred to as the Main zone, contains a well-fractured, brecciated and altered biotite-hornblende quartz monzonite, granite or granodiorite with disseminations, blebs and fracture coatings of molybdenite and trace chalcopyrite. Molybdenite is also reported to be associated with potassium feldspar-quartz veinlets. Alteration includes silicification, sericitization, oxidation and chloritization.
In 1957, surface sampling of an open-cut yielded up to 3.8 per cent molybdenum over 0.45 metre and 0.31 per cent molybdenum over 3.0 metres, whereas diamond drilling at the time yielded 0.17 per cent molybdenum over 4.5 metres in hole no. 3 (Property File - McDougall, J.J. [1957-12-19]: Report on Barriere Molybdenite and Christina Lake Molybdenite). Other samples are reported to have yielded up to 0.02 per cent niobium and 27.4 grams per tonne silver (Property File - McDougall, J.J. [1957-12-19]: Report on Barriere Molybdenite and Christina Lake Molybdenite).
In 1980, grab samples yielded from 0.15 to 0.35 per cent molybdenite, or 0.09 to 0.21 per cent molybdenum (Assessment Report 8952). The following year, a drill hole (DDH T 81-2), located on the ridge approximately 700 metres to the east, intersected two similar zones of mineralization yielding 0.030 and 0.025 per cent molybdenite (0.018 and 0.015 per cent molybdenum), respectively, over 15.2 metres (Assessment Report 10111).
In 2005, rock samples from the main zone yielded up to 0.365 per cent molybdenum, whereas two other samples taken approximately 500 metres to the south and 1.3 kilometres to the east- south east yielded 0.131 and 0.111 per cent molybdenum, respectively (Property File - Murray, K. [2005-10-02]: Geochemical survey map - Luxor property).
In 2007, diamond drilling yielded intercepts of 0.093 per cent molybdenum over 3 metres in hole LX07-01, 0.068 and 0.030 per cent molybdenum over 3 and 6 metres, respectively, in hole LX07-02 (Assessment Report 29974). Hole LX07-02 also yielded 0.007 per cent uranium over a 3-metre interval (Assessment Report 29974).
In 2009, diamond drilling yielded intercepts of 0.030 per cent molybdenum over 18.0 metres, including 0.065 per cent molybdenum over 6.0 metres in hole LX10-5; 0.055 and 0.046 per cent molybdenum over 3 metres in hole LX10-6 and 0.079 per cent molybdenum over 6 metres, including 0.115 per cent molybdenum over 3 metres, in hole LX10-7 (Assessment Report 32351).
The area has been explored since at least the 1950’s, with programs of diamond drilling and trenching performed on the area as the Pat claims. In 1980, A.P.I. Mineral Exploration Corp. completed a program of silt sampling and a diamond drill hole, totalling 305 metres, on the area as the Tony claims. The following year, a program of soil sampling and a diamond drill hole, totalling 609 metres, were completed. In 1982, a program of geological mapping was performed. In 2005, the area was prospected and sampled as the Luxor property. In 2007, Kingsman Resources completed four diamond drill holes, totalling 722.0 metres. In 2009, a program of soil sampling and a 21.0 line-kilometre ground magnetic and electromagnetic survey were completed. In 2010, a further seven diamond drill holes, totalling 1066.0 metres, were completed.
