Summary:
The Jaurdi Gold Project overlies a portion of the Bali Monzogranite immediately adjacent to the Jaurdi Hills-Dunnsville greenstone sequence, which in the south hosts the Jaurdi Hills mining centre and the Dunnsville mining centre towards the north. The Bali Monzogranite and Dunnsville Granodiorite/Doyle Dam Granodiorite to the north, together occupy the core of a gently north plunging anticline. M16/529 is located to the west of the anticlinal axis and immediately adjacent to the granite-greenstone contact.
The Bali Monzogranite is poorly exposed. The greenstone-granite contact is foliated where exposed. Shear zones developed locally within the adjacent greenstones, may continue within the granite. Gold mineralised palaeochannels are known in the Jaurdi Hills area, particularly to the west and south of the Jaurdi Hills mining centre.
Regional magnetic data suggest that the western portion of the project lies within a broad demagnetised corridor following the western contact of the Bali Monzogranite, and which may continue in a north-northwest direction through the greenstone sequence to Dunnsville. A magnetic dyke, akin to the Parkeston dyke in the Kalgoorlie area, has intruded this corridor. Another paired east-northeast magnetic dyke set is located immediately to the south of the project area. This dyke set is part of the regionally extensive Widgiemooltha Dyke Suite, and passes to the north of Kalgoorlie-Boulder.
Lost Dog
The Lost D ........

Summary:
Mining method at the Jaurdi Project is conventional open-pit. The Jaurdi Life of Mine is scheduled from 1st July 2021 – 30th June 2027 and includes the Lost Dog pit, existing stockpiles, and the Black Cat South pit.
Lost Dog
Mining method is conventional open pit with drill and blast, excavate, load and haul. The ore zone geometry coupled with the low stripping ratio (<2.5 (waste) to 1 (ore) and maximum pit depth (<32.5m) indicate that Lost Dog is most suited to mining by conventional open pit mining methods.
Black Cat South
Mining method is conventional open pit with drill and blast, excavate, load and haul. The ore zone geometry coupled with the low stripping ratio (9.5 (waste) to 1 (ore) and maximum pit depth (70m) indicate that Black Cat South is most suited to mining by conventional open pit mining methods.
Beacon envisages that load and haul activities will be undertaken by owner miner operators using a mixture of owned and dry hired equipment.

Reserves at June 1, 2022:
Lost Dog: MRE is comprised of transported clays and cemented silcrete and is presented at a 0.5 g/t cut-off value.
Black Cat: the Mineral Resource comprises oxide, transitional and fresh rock and is presented at a 0.5 g/t cut-off value.
A mining recovery factor of 98% was used for Lost Dog and 95% used for Black Cat. For Ore Reserves, a cut-off grade of 0.5 g/t was calculated for both Lost Dog and Black Cat, based on a gold price of $2,500 per ounce.
