• Reconciled November production of 4,652oz Au, lower than initial estimate
• Identified sub-optimal leaching conditions affecting recovery
• Confident recoveries will return to historical +90% levels with modified leach conditions

Brightstar Resources Ltd (ASX: BTR) has provided an update on the recent processing campaign through Genesis Minerals' Laverton Mill. The November campaign (Parcel 4) resulted in reconciled production and sales of 4,652oz Au, which is a revision from the initial unreconciled production of 6,300oz Au. The final campaign recovery was 75%, compared to the 83% previously reported, due to final gold-in-circuit reconciliation and based on provided mill data. Brightstar, in consultation with its independent metallurgical advisors, has identified sub-optimal leaching conditions for the processing campaign, which adversely affected the parcel's recoveries. The Parcel 4 contained an increased proportion of Pyrrhotite-bearing Fish ore in the blended parcel, which contributed to conditions of low dissolved oxygen levels in the leaching circuit. Both the Second Fortune and Fish mines have significant previous mining and processing history, and detailed metallurgical test work completed, which outline recoveries of over 90% under conventional CIL leaching conditions. Brightstar and its metallurgical consultants are confident recoveries will return to historical levels of over 90% with modified leach conditions. The prior campaign completed in August had a total parcel recovery of 91.3%. Current mining operations continue to perform well, with the Fish mine delivering 33kt @ 3.3g/t Au for approximately 3,450oz in the last seven weeks (November and December MTD) of operations.

Brightstar continues to advance the Goldfields assets base towards a Final Investment Decision early next calendar year, with technical work streams for the Goldfields 'DFS 2.0' nearing completion including updated mine plans, an increased mill throughput scenario delivering improved gold production output and financial metrics. The company is targeting improvements to the June 2025 DFS which outlined average production of 70,000oz per annum for five years with AISC below A$2,991/oz.
