Volt Resources Limited (ASX: VRC) ('Volt' or 'the Company') is pleased to announce the completion of the latest production campaign at the Zavalievsky Graphite ('ZG') mine in Ukraine . Key Highlights Production volumes: From 14 July to 13 August 2025 ZG produced 830 tonnes of graphite concentrate at grades ranging from 78-97 % Total Graphitic Content (TGC). A portion of this concentrate will be further refined to 99.5 % purity to meet specific customer requirements. Sales commitments: Approximately 580 tonnes (around 70 % of the campaign output) have been contracted to existing customers in Japan and Europe and to a new North American customer. This demonstrates continuing demand and supports the Company's market position. Product quality: Small, medium and large flake graphite concentrate was produced with grades between 78 % and 97 % TGC. Cost performance: Despite elevated electricity prices in Ukraine , the campaign achieved a unit production FOB cost of US$540 per tonne of graphite concentrate. Community and operational impact: The campaign maintained employment in the Zavallya region and provided economic stability for the local community. During the campaign the Company identified opportunities for equipment upgrades and a preventative maintenance system to maximise uptime and operational efficiency Proceeds from these sales are received by Volt subsidiary Zavalievsky Graphite ( ZG Group ). On 26 July 2021 , Volt completed the acquisition of a 70% interest in the ZG Group . Given the joint control of the ZG Group , Volt's 70% interest is accounted for using the equity method in the consolidated financial statements. Per the advice from our auditors and under the requirements of IFRS, ZG revenues are not consolidated into Volt's balance sheet or profit and loss or cashflow reporting. Volt Resources CEO, Prashant Chintawar , commented: 'The completion of this campaign demonstrates the capability of our Zavalievsky team to operate in a challenging environment. We are encouraged by sustained customer demand and will continue to manage costs prudently while maintaining operational discipline. Our strategic focus remains on advancing the broader Volt portfolio to support energy transition and critical mineral supply chains.'
