TRX Gold Achieves Sulphide Gold Recovery of 88.7% from Its Existing Processing Plant

TORONTO, June 15, 2023 - TRX Gold Corp. (TSX:TNX) (NYSE American:TRX) (the "Company" or "TRX Gold") is pleased to provide a significant operational update for Buckreef Gold as well as a preview to the Company's Q3 2023 financial results.

Significant operational update

The Company is happy to announce important preliminary results from bulk sample testing at the Buckreef Gold mine. Over 6,500 tonnes of sulphide ore have been successfully processed through Buckreef Gold's existing milling facility, achieving an indicative gold recovery of 88.7%. This is a significant achievement as approximately 90% of Buckreef Gold's 2 million+ ounce gold mineral resource is held in sulphide material, thus unlocking the significant economic potential of the project. This bulk sample test indicates that the Company can process sulphide ore through its existing processing plant, thus minimizing capex for future plant expansions.

"The results from this bulk sample demonstrate that we can process sulphide material through our existing processing plant, which has been successfully processing oxide material for close to 24 months. We are excited at the optionality this creates for near term mine planning and the positive impact these results will have on project economics for future plant expansions, as we have been able to construct plants very cost effectively compared to other plants elsewhere," noted TRX Gold CEO Stephen Mullowney.

Concurrent with this bulk sample test, the Company also recently completed an upgrade to the Buckreef Gold crushing system contributing to the successful recovery rates from sulphide material using a simple, straightforward flowsheet consisting of crushing, grinding, and carbon in leach.

The Company continues to refine the existing circuit to improve both gold recovery and throughput, while the 18-hole metallurgical study undertaken by SGS (South Africa) is ongoing. The bulk sample results along with ongoing production data will be combined with the metallurgical variability study to help in identifying any further improvements or enhancements to the existing flowsheet.

Q3 2023 Financial Results Preview

The Company is also pleased to announce preliminary Q3 2023 results for the period from March 2023 to May 2023. Results include Q3 2023 production of 4,764 ounces of gold and sales of 4,810 ounces of gold.

The Company continues to expect full year fiscal 2023 production to be between 20,000 - 25,000 ounces of gold, which is unchanged from when it was originally estimated and released in November 2022.

The average market price for gold in Q3 2023 was approximately $1,963 per ounce.

TRX Gold will provide additional discussion and analysis regarding its third quarter 2023 production and sales when the Company reports its quarterly results in July 2023.
