The Golden Highway (formerly known as the Attila-Alaric Trend), is located just 25 kilometres west of the Gruyere Gold Mine and processing plant on the western side of the Yamarna Greenstone Belt. Most of the greenstone sequence is obscured by a veneer of Quaternary sand and lake deposits.
Mineralisation is focused along a trend of highly sheared mafic and intermediate volcanics and sediments parallel to and within the Yamarna Shear Zone. Mineralisation has been traced over 50 kilometres in strike.
Golden Highway Ore Reserve currently sits at 6.5 million tonnes at 1.5 g/t Au for 310,000 ounces of which only 180,000 ounces are incorporated into the current Gruyere Mine Plan. The remainder of the Reserves will be incorporated in future mine plan updates.
The Golden Highway Mineral Resource currently sits at 15.6 million tonnes at 1.5 g/t Au for 730,000 ounces. The Resources are hosted across the Alaric, Montagne, Argos and Attila deposits on the Golden Highway and the Yam14 deposit to the south of the Gruyere Deposit. The Golden Highway Trend also hosts the high-grade Central Bore Inferred Resource of 0.24 million tonnes at 13.05 g/t Au for 100,000 ounces.
