Kirkland Lake Discoveries completes inaugural program at Hurricane Zone

Apr 4, 2024

Kirkland Lake Discoveries Corp. has completed its Phase 2 drill program safely and efficiently at the Hurricane Intrusive Zone on the Lucky Strike Property. A total of thirteen drill holes aggregating 3,376 metres were drilled at six targets, completing the second of three phases previously announced.

The Hurricane Intrusive Zone, which was the subject of prospecting, mapping, and airborne magnetics in 2023, is a geophysical anomaly with copper and gold mineralization associated with intense alteration from syenite intrusive bodies. The drill program was designed to test the geology and assess the continuity of mineralization observed in outcrop during the summer mapping and prospecting programs.

The Hurricane Intrusive Zone bears similarity to the rocks and mineralization found at Agnico Eagle Mines Limited's ("Agnico") Upper Beaver deposit, which is six km to the southwest. Upper Beaver is a gold-copper deposit that is mainly hosted in the Upper Beaver alkalic intrusive complex and the surrounding basalts it intruded. It is associated with disseminated pyrite and chalcopyrite, and magnetite-sulphide veining associated with strong magmatic-hydrothermal alteration. The mineralization occurs as elongated tabular bodies that strike northeast, dip steeply northwest and plunge 65 degrees to the northeast. The mineralization has been defined along a 400m strike length from the surface to a depth of 1,800m and remains open at depth. 

Queenston Mining Inc. sold the 1.1-million-ounce (Moz) deposit to Osisko Mining Corp. ("Osisko") for $550 million in 2012. Osisko, in turn, sold the project to Agnico in 2014 and Agnico has since expanded the resource at Upper Beaver. As at December 31, 2022, Upper Beaver had approximately 1.4 Moz of gold and 20,000 tonnes (t) of copper in underground probable mineral reserves (8.0 Mt grading 5.43 g/t gold and 0.25% copper); 403,000 oz of gold and 5,100 t of copper in underground indicated mineral resources (3.6 Mt grading 3.45 g/t Au and 0.14% copper); and 1.4 Moz Au of gold and 17,300 t of copper in underground inferred mineral resources (8.7 Mt grading 5.07 g/t Au and 0.20% copper). An updated mineral resource for the Upper Beaver Deposit was expected in late 2023 but has yet to be released.1
