Ausgold (AUC) Investor Presentation summary

Project overview and financial highlights

• Katanning Gold Project in Western Australia targets a 10-year open pit mine life with strong gold production and financial returns.

• Post-tax cashflow of A$1.37B, NPV5 of A$954M, and IRR of 53% at a gold price of A$4,300/oz; payback in 13 months from first production.

• Initial production is targeted for late CY2027, with a pre-production CAPEX of A$355M.

• Life-of-mine average production is 113.7koz/year, with 1.14Moz total production and 90.4% recovery.

• All-in sustaining cost (AISC) is A$2,180/oz for the first 4 years and A$2,265/oz over the mine life, positioning the project in the lower half of the cost curve.

Resource and reserve details

• Mineral Resource: 2.44Moz @ 1.11g/t Au (91% Measured & Indicated), constrained at A$4,500/oz pit shell.

• Ore Reserve: 1.25Moz @ 1.11g/t Au (84% Proven), calculated at a conservative A$3,000/oz gold price.

• 90% of the total resource sits within a single, optimised open pit, improving mine design and scheduling.

• Updated resource and reserve models are more robust and ready for mining, with significant de-risking.

Operations, processing, and permitting

• Processing via a 3.6Mtpa CIL gold plant with conventional crushing, SAG, and ball mill; gravity recovery of 25% LOM.

• Plant design allows for future expansion; gold recovery rates average above 90% throughout mine life.

• Permitting underway, with project footprint designed to minimise environmental disturbance and integrated landform for waste and tailings.
