The Mt Edwards Nickel and Faraday–Trainline Lithium Projects are located near Widgiemooltha, approximately 80 km south of Kalgoorlie-Boulder and 30 km south of Kambalda. • The Mt Edwards Nickel Project is a collection of ten (10) nickel deposits with a combined mineral resource of 12.33Mt at 1.42% Ni for 174,540t of contained nickel. • The Faraday-Trainline Lithium Project hosts a reported mineral resource of 1.96 Mt at 0.69% Li2O1 . In the Kimberley region, the Butchers Creek Gold Project lies 30 km southeast of Halls Creek. The project is centred on a historic gold production area and hosts a global Mineral Resource of 5.6 Mt @ 1.98 g/t Au for 359,000 ounces2 of gold. Historical mining between 1995 and 1997 produced approximately 52,000 ounces. The Radio Gold Project, located 8 km north of Bullfinch and approximately 38 km northwest of Southern Cross, is another cornerstone asset within WIN’s portfolio. Over its mine life, Radio produced roughly 71,000 ounces of gold at an average grade of 38 g/t Au. WIN’s 2026 global Mineral Resource Estimate for the Project totals 366,000t @ 4.22 g/t Au for 49,6003 ounces of contained gold.
