Calidus acquired the Nullagine Gold Project (Nullagine) that covers ~65km of strike-length of the highly prospective Mosquito Creek Basin in December 2023.
Nullagine adjoins the Blue Spec (190koz @ 24.3g/t Au) and Felix projects, consolidating this area as a future production hub for Calidus.
Nullagine lies entirely within the Mosquito Creek Basin, which was deposited on ancient granite–greenstone terrains on the eastern edge of the Pilbara Craton. Most mineralisation in the belt comprises quartz vein-hosted, gold-antimony deposits along the east-northeast-trending Blue Spec Fault Zone and quartz vein-hosted, gold deposits along the parallel Middle Creek Fault Zone 5–10km to the south.
Nullagine is an established mine site and hosts significant existing infrastructure, including the recently operational 1.8Mtpa Golden Eagle Processing Plant, a 230-person accommodation village, administration buildings, workshop, warehouse, laboratory, 10MW power station, communications network, water supply, storage and tailings facilities. The Golden Eagle processing facility is located approximately 9 km south of Nullagine via State Route 138.
From 2012 to 2019, Nullagine produced 543,000oz of gold @ 1.6g/t and 87% recovery when the gold price averaged A$1,500/oz. Under Novo ownership, Nullagine produced a further 128,000oz between 2021 and 2022. The Golden Eagle Mill was placed on care and maintenance following completion of mining of the existing oxide mining inventory in August 2022. The processing plant is in good condition with the ball mill emptied and jacked.
Calidus has acquired Nullagine to maximise its options for producing gold in the East Pilbara. Nullagine provides an immediate option for feeding higher grade oxide ore to Warrawoona (75km) but also a longer-term option of centring a new production hub at Nullagine to treat sulphide ores from both the combined ground holdings.
