Asante Gold Corporation Begins Operations at Bibiani Mine
Asante Gold Corporation (TSXV: ASE | OTCQX: ASGOF) is excited to share the latest developments concerning its sulphide plant at the Bibiani Gold Mine, positioned in Ghana. This operational milestone reflects the Company's commitment to becoming a leading mid-tier gold producer, making significant strides in enhancing mining and processing capabilities.
Recent Achievements
In the ongoing efforts to streamline operations at the Bibiani mine, the Company has prioritized health and safety measures, maintaining an impressive Lost Time Incident Frequency Rate and a Total Recordable Incident Frequency Rate of 0.00 for the year to date. Financially, the project remains on target with a total expenditure of US$32M, fully aligning with the budget.
Significant Operational Updates
Key updates following the completion of construction and commissioning include:
- The sulphide treatment plant has started operating on a 12-hour daily basis since September 27, 2025.
- Transition to a 24-hour operational schedule is scheduled for September 30, 2025, with optimization efforts aimed at achieving an extraordinary +85% gold recovery through October.
- Expected increase in gold recovery rates from 60% to an impressive 92% by late October 2025 demonstrates the plant's effectiveness.
- The projected plant capacity stands at 4 million tonnes per year, ensuring the ability to handle vast amounts of ore efficiently.
Understanding the Sulphide Plant Process
The construction of the sulphide plant marked a significant stage in late 2024 and has been designed specifically to recover gold found within sulphide mineralization occurring in ore deposits below a depth of 110 meters. Notably, approximately 30% of the gold in these deposits is trapped within sulphides and is particularly fine, measuring just 35 microns.
The current operational process flow includes advanced flotation techniques, regrind initiatives to reduce the particle size to 25 microns, and the utilization of innovative Aachen reactor technology. This approach aims to elevate oxygen levels in the high-intensity leach process and utilizes carbon in pulp (CIP) systems for effective gold recovery. Both flotation and sulphide treatment tailings will return to the carbon-in-leach (CIL) plant for further treatment, significantly boosting recovery rates as outlined in the Bibiani technical report published earlier this year.
Collaboration with Key Partners
Collaboration has been instrumental to the success of the Bibiani sulphide plant. The rigorous process testing was conducted by ALS in Australia, establishing efficient methodologies for operation. Key equipment suppliers include FlSmidth from the USA, MO Group from Europe, and Maelgwyn based in South Africa. Project design was expertly managed by Mining Process Project Engineering, while project oversight fell to Jet-Rom Engineering in Ghana.
Future Prospects and Company Vision
Looking ahead, Asante Gold Corporation is committed to enhancing its gold production capabilities through strategic capital allocation across both the Bibiani and Chirano mines. President and CEO Dave Anthony emphasized the importance of this operational phase, indicating plans to ramp up production to between 450,000 and 500,000 ounces of gold annually. This projection highlights the Company's focus on scaling operations and optimizing recovery processes.
Asante's ongoing exploration initiatives, including work at the Kubi Gold Project and other nearby sites, underscore a robust growth strategy aimed at expanding their footprint in the vibrant gold-producing regions of Ghana.
