On February 1, 2024, Canadian Copper Inc. (CSE:CCI) (“Canadian Copper” or the “Company”) announced that it satisfied all conditions required to acquire 100% of the Murray Brook deposit and its surrounding prospective exploration property (“Murray Brook Project”) located in the prospective Bathurst Mining Camp in New Brunswick, Canada.

Subsequent to the purchase of VM Canada’s and MetalQuest’s interests in the Murray Brook Project, mine lease ownership and title transfer will require Ministerial approval under the Mining Act in New Brunswick. Pending consent by the Minister, ownership and title will transfer to Canadian Copper.

Summary:

The Murray Brook sulphide mineralization is classified as a volcanogenic massive sulphide deposit (P., W., C., Shanks III, et al) 2009. This type of deposit is characterized by massive to semi-massive iron sulphide minerals including variable amounts of base metals and precious metals. This type of deposit is well studied and documented. Genetically the deposits are coeval with felsic volcanic centres, and are generally lens-like, parallel to the stratigraphy, with a discordant hydrothermal “pipe” at the stratigraphic base of the sulphide accumulation.

As is well illustrated by the discovery of the Murray Brook deposit, heavy mineral and soil geochemical surveys are an effective search tools. Geophysical surveys including magnetic, electromagnetic, induced polarization/ resistivity, and gravity surveys are also effective exploration tools for concealed deposits.

The Murray Brook deposit is hosted by sedimentary rocks of the Charlotte Brook Member in the lower part of the Mount Brittain Formation. The upper felsic volcanic member of the Mount Brittain Formation is host to the Restigouche deposit, some 10 km to the west. The Mount Brittain Formation is believed to be equivalent of the Spruce Lake Formation which hosts the Caribou Mine, ten kilometres to the east.

The sulphides are massive to semi-massive, locally banded and pyrite-rich. The deposit has a 1 to 3 m wide halo composed of chloritized sedimentary rocks containing disseminated pyrite. The hanging wall is moderately chloritic and is locally intensely deformed. The footwall consists of fine grained felsic tuff, and tuffaceous sediments with moderate to strong chlorite and sericite alteration.

Sulphides are mainly fine grained, massive, vaguely laminated pyrite with disseminated and banded sphalerite, chalcopyrite and galena, with minor tetrahedrite, covellite, marcasite and arsenopyrite.
