The Invincible Project – 100% owned by BMG – is located in the Central Pilbara and is immediately along strike from, and hosted by the same stratigraphy as, the producing 1.5Moz Au Warrawoona Gold Mine. Two granted exploration licences comprise BMG’s project – E45/4553 and E45/6222.
In 2025, the Creasy Group took control and ownership of Calidus Resources (which had established the mine) through a Deed of Company Arrangement approved by creditors on 6 January 2025. With this acquisition, the Creasy Group becomes the dominant gold player in the Central Pilbara.
In addition to the Warrawoona Gold Project, the Creasy Group now also owns the Beatons Gold Project and the Nullagine Gold Project in the Central Pilbara.

Invincible hosts more than 12.5km of the Warrawoona Shear Zone – the mineralised trend that hosts the Calidus gold resource, referred to as the Klondyke deposit; see Figure 3. A soil survey completed by BMG at Invincible has identified a gold trend that extends for more than 5km over the Warrawoona Shear Zone, providing a compelling target for follow-up drilling.
Gold mineralisation at the Project is interpreted to be primary reef gold that is hosted in quartz veins within extensive shear zones, similar to the mineralisation at the Calidus project. The Warrawoona Group is sandwiched between the Mount Edgar Granitoid Complex to the north and the Corunna Downs Granitoid Complex to the south, and as such is strongly deformed and mylonitised. Coarse, visible gold is common.
The prospectivity at Invincible is also underscored by the presence of multiple small artisanal workings including the historic Invincible mine, where 21.8kg of gold was mined at a grade of 1,600.85 g/t Au. These historic workings targeted the near surface high-grade gold that is prevalent in the area. There is very limited deeper drilling across the Invincible tenure – and no drilling underneath the historic Invincible mine.
Prospecting at the Invincible tenure in recent years continues to discover surface and near-surface gold nuggets. Figure 2 shows a photo of quartz vein hosted gold nuggets recovered in 2018 and reported in Advice of Minerals Recovered within Section 40E Permit Area dated 8 October 2018 and filed with the Department of Mines, Industry Regulation and Safety.
This Advice reported the following recovery using a metal detector:
“8 nuggets from 1 to 6 grams & 2 specimens (golf ball size) containing 1oz and 2oz of gold.”

Visual interpretation of samples and/or visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where concentrations or grades are the factor of principal economic interest. Laboratory assays are required to determine the presence and grade of any contained mineralisation.
