The Bur (Breccia) occurrence is located south of the Taseko River, approximately 1.5 kilometres east- southeast of the rivers’ junction with Granite Creek.

The area is underlain by volcanic rocks of the Upper Cretaceous Powell Creek Formation and granodiorite of the Upper Cretaceous Coast Plutonic Complex.

Locally, at the Breccia zone minor chalcopyrite and molybdenite mineralization occurs with pyrite as disseminations and stockworks within rusty and weathered granodiorite.

Another anomalous zone, referred to as the Central zone, is located approximately 600 metres to the south.

In 1969, a drill hole (A-6), located immediately northeast of the Taseko River, is reported to have yielded 153.2 grams per tonne silver over 3.0 metres (Westphal, M.W. (2011-03-10): Technical Report – Taseko Mineral Property).

In 1970, a drill hole (S-1), located on the Breccia zone, yielded 0.20 per cent copper over 30 metres, including 0.45 per cent copper over 6 metres (Westphal, M.W. (2011-03-10): Technical Report – Taseko Mineral Property).

In 1976, drilling on the Breccia zone yielded intercepts of up to 0.32 per cent copper over 6.0 metres in hole Q-33 (Westphal, M.W. (2011-03-10): Technical Report – Taseko Mineral Property).

In 1989, a drill hole (89-13) located southwest of the Breccia zone yielded 0.27 per cent copper and 0.2 gram per tonne gold over 0.9 metre (Westphal, M.W. (2011-03-10): Technical Report – Taseko Mineral Property).

In 1991, diamond drilling of the Breccia zone yielded intercepts of 0.14 per cent copper and 0.17 gram per tonne gold over 80.1 metres in hole 91-38, 0.61 and 0.72 per cent copper with 0.82 and 0.58 gram per tonne gold over 14.1 and 13.2 metres, respectively, in hole 91-39, 0.13 per cent copper over 43.5 metres in hole 91-40, 0.32 and 0.56 per cent copper with 0.28 and 0.17 gram per tonne gold over 59.7 and 19.8 metres in hole 91-54 and 0.26 per cent copper with 0.08 gram per tonne gold over 29.1 metres in hole 91-55 (Westphal, M.W. (2011-03-10): Technical Report – Taseko Mineral Property).

Work History

The area has been explored in conjunction with the nearby Taseko (MINFILE 092O 033) and Buzzer (MINFILE 092O 038) occurrences and a completed property exploration history can be found there. Drilling was performed on the Breccia zone in 1969, 1970, 1976, 1989, 1991 and 1993, while the Central zone was drilled in 2008.

During 2014 through 2019, Amarc Resources Ltd. completed programs of geological mapping, geochemical (talus fines, rock chip and stream sediment) sampling, 163.6 line-kilometres of induced polarization surveys, 1069 line-kilometres of airborne magnetic surveys and 18 157 metres of diamond drilling on the area as part of the IKE project. The majority of the drilling (15 455.34 metres in 26 holes) was completed on the IKE (MINFILE 092O 025) occurrence.
