The MCC occurrence is located at an elevation of approximately 1500 metres, near a pass separating the headwaters of Birk and Chu Chua creeks.

The area is underlain mainly by Paleozoic rocks of the Eagle Bay assemblage and Fennell Formation. The Eagle Bay assemblage comprises Early Cambrian to Mississippian metasedimentary and metavolcanic rocks that are locally intruded by Devonian orthogneiss. The Fennell Formation (Slide Mountain Group) comprises Devonian to Permian oceanic rocks which were tectonically emplaced over Mississippian rocks of the Eagle Bay assemblage. The Fennell and Eagle Bay rocks were deformed and metamorphosed together; the metamorphic grade is lower greenschist through most of the area but increases sharply to amphibolite facies in places. The Fennell and Eagle Bay successions are cut by mid-Cretaceous granitic rocks of the Raft and Baldy batholiths, and by Early Tertiary quartz feldspar porphyry, basalt and lamprophyre dikes. They are locally overlain by Eocene sedimentary and volcanic rocks of the Kamloops Group and by Miocene plateau lavas.

A thick pile of massive to pillowed basalts with local pods and layers of cherty tuff and greywacke comprise the lower part of the Fennell Formation in the area. Stratigraphically upward these give way to massive basalt, then through a transitional zone of basalt, chert, phyllite, quartz feldspar porphyry and intraformational chert conglomerate into overlying phyllites and turbiditic sandstones of the Eagle Bay assemblage. Rocks of the Fennell Formation are generally not highly foliated. The schistosity, where developed, is axial planar to early, generally northeast plunging isoclinal folds. The schistosity is itself folded about two generations of later folds with generally east and northwest trends.

Locally, as identified by drilling (Hole MCC-56), a sequence of sericite altered sediments, argillite and magnetic diorite sills host a 3.7-metre-wide cherty interval containing 1 to 3 per cent bedded pyrite, trace chalcopyrite, and a 15 centimetre wide interval of massive sulphide with approximately 3 per cent chalcopyrite. The mineralized zone was intersected at a depth of approximately 89 metres.

Drill hole MCC-56 yielded 1 per cent copper and 9 grams per tonne silver over 0.15 metre (Raffle, K. (2013-01-25): Technical Report on the Chu Chua Property). Three other drill holes (MCC-37 through MCC-39) tested the potential for additional mineralization to the north and south but did not intersect massive sulphides

Work History

In 1990, Minnova completed eight diamond drill holes (MCC-52 through MCC-59) which were completed to test coincident EM and magnetic anomalies near a pass separating the headwaters of Birk and Chu Chua creeks.

The area has been explored in conjunction with the nearby Chu Chua (MINFILE 092P 140) occurrence and a completed property exploration history can be found there.
