The Stratmat Project is within the Bathurst Mining Camp (BMC) which occupies a roughly circular area of approximately 70-km diameter in the Miramichi Highlands of northern New Brunswick. The area boasts some 46 mineral deposits with defined tonnage and another hundred mineral occurrences, all hosted by Cambro-Ordovician rocks that were deposited in an ensialic back-arc basin. The project is underlain by a magnetic northeast-southwest trending sequence of predominantly felsic volcanic rocks and lesser sedimentary rocks which are host to all massive sulphide deposits on the property. Provincial Government regional mapping projects have classified the rocks as belonging to the Flat Landing Brook Formation of the Middle Ordovician Tetagouche Group.
The sulphide minerals consist of disseminated and massive sphalerite-galena-pyrite and chalcopyrite. The sulphide minerals are fine to medium-grained, and are coarser than those typically found in deposits of the Bathurst-Newcastle district. Disseminated mineralization, commonly of economic grade also occurs in the phyllitic sedimentary rocks as well as in the talc layers which locally grade into massive sulphide.
