Hammaslahti Copper-Zinc Mine in Finland

HAMMASLAHTI COPPER-ZINC

Hammaslahti is considered prospective for volcanogenic massive sulphide (‘VMS’) mineralisation. The historic Hammaslahti mine exists within the Company’s licence area; total run of mine production was ±10Mt at an average grade of 1.16% copper, 1.55% zinc, 0.59 g/t gold and 5.2 g/t silver (operational between 1973 and 1986, initially developed as an open pit mine before being expanded underground).

Drilling by Bluejay has identified previously unknown extensions to the Hammaslahti mine mineralisation with multiple intersections of high grade massive sulphides. Examples of this extensional mineralisation are 3.4m @ 11.5% copper and 3 ppm silver. Two main target areas have been identified for further exploration.

Recent drilling by FinnAust intersected a Felsic/Graphite Schist contact, 118m deep and 2 km east of the Hammaslahti mine. These geophysical anomalies are interpreted to be a repetition of the mine’s alteration and mineralisation system along strike. This project is a high priority target area.

Finland

Bluejay holds a strategic portfolio of high grade copper, zinc and nickel assets in Finland covering approximately 4,710sq km. This land package comprises three primary project areas – the Hammaslahti, Outokumpu and Enonkoski projects. The projects are located in a prolific geological belt in south east Finland.

Finland is one of the largest producers of nickel, copper, chromite, copper and zinc in Europe and has a vibrant mining and exploration industry. With a pro-mining government, low sovereign, and a highly skilled mining workforce available, the country is an attractive investment destination.

Outokumpu Copper Project

The Outokumpu licence covers the majority of the north-south trending Outokumpu Copper Belt in Finland, which has produced several high-grade copper mines, including the world famous Outokumpu Copper mine which produced 57mt @ 3.1% Cu + polymetallic credits between 1908-1988.

6 drill ready targets have been identified to date, which the Company views as having good potential for hosting high grade copper along strike from and immediately adjacent to the aforementioned Outokumpu Copper mine.

Enonkoski Nickel-Copper PGE Project

Enonkoski includes a previously producing nickel-copper mine, which reportedly produced 6.7Mt at an average grade of 0.8% of nickel (‘Ni’) between 1984 and 1994. Bluejay has confirmed extensions and repeats of high grade nickel, copper and PGE mineralisation 2km south east of the old Enonkoski Mine, with best historic drill intercepts include 15m @ 6.9% Ni, 2.0% of copper (‘Cu’) and 0.33% of cobalt (‘Co’). The Enonkoski mine is located in south-eastern Finland, to the southwest of Outokumpu, which can also be described as the southern end of the Kotalahti Nickel Belt.
