The Golden Highway (formerly known as the Attila-Alaric Trend), which includes the resources at Attila and Alaric, is located on the western side of the Yamarna Greenstone Belt within the Archaean Yilgarn Craton. Most of the greenstone sequence is obscured by a veneer of Quaternary sand and lake deposits.
Gold was first discovered on the Yamarna Greenstone Belt in the early 1980’s and the first Resource completed in 1994 on the Attila Project to the south of Alaric. Subsequent exploration focussed on this mineralised trend of highly sheared mafic and intermediate volcanics and sediments parallel to the Yamarna Shear Zone. Mineralisation has been traced over 50 kilometres in strike. The Attila and Alaric Mineral Resources were updated to comply with JORC Code 2012 Edition standards in 2015. Following positive economic evaluation of both the Attila and Alaric deposits, further drilling was completed during 2016 and 2017.
Following completion of a Pre‐feasibility Study into developing Attila and Alaric as open pit mines to provide satellite feed to the Gruyere Process Plant. Attila and Alaric are within economic trucking distance of the Gruyere Process Plant and offer a source of supplementary mill feed during the Gruyere mine life. A combined Ore Reserve of 3.59 million tonnes at 1.55 g/t Au for 179,000 ounces of gold has been established for these deposits.
The Mineral Resource for the Attila-Alaric Trend satellite deposits, 25 kilometres to the west of Gruyere, increased by 175,000 ounces to 596,000 ounces with the addition of new estimates for the Argos and Montagne deposits (historically reported as Alaric 1 and Alaric 2 respectively), and minor reductions in the Attila and Alaric deposits.
New resource estimates completed for the Argos and Montagne deposits along the Attila-Alaric Trend have added 1.9 million tonnes at 1.27 g/t Au for 78,300 ounces and 2.9 million tonnes at 1.34 g/t Au for 128,400 ounces respectively.
