TRX Gold Advances Larger Mine Development at Buckreef Gold

TORONTO, April 11, 2023 - TRX Gold Corp. (TSX: TNX) (NYSE American: TRX) (the "Company" or "TRX Gold") is pleased to provide an update on the advancement of the larger Buckreef Gold mine development project, in which ongoing work on a number of different fronts will allow the Company to grow the currently producing Buckreef Gold Mine to a significant operation.

Update highlights:

• Geotechnical characterization has been ongoing as both consultants, SGS Canada and Terrane Geoscience, industry experts in geology, engineering and rock mechanics, have been to the Buckreef Gold project site over the past 4 weeks to complete their field work and drill hole analyses. This work will, in the near term, help optimize pit slopes to enhance the mining plan and reduce waste rock mining.
• The metallurgical variability studies focusing on the project's next 5 to 7 years have continued to advance. Drill core from a total of 18 metallurgical holes (2,367 meters) along the entire strike of the Buckreef Main deposit have now been received by SGS in South Africa for metallurgical testing. Results from these studies will inform the Buckreef team in the mid- to long-term, which processing flowsheet is the most efficient, effective and profitable for the larger project. In the near term, this work will help determine whether sulphide ore material can be processed through Buckreef Gold's current processing plant. The results of this work will be fully incorporated into future Technical Reports and economic analysis.
• The Company expects to release drill results from the Anfield and Eastern Porphyry zones in the next few weeks.
  

"The Company is committed to growing its Buckreef Gold Mine into a significant operation. Therefore, I am pleased to inform the market of the successful completion of SGSC - Terrane Geosciences geotechnical fieldwork, and the dispatch of the 18-hole metallurgical samples to SGS in South Africa for variability analysis," commented Stephen Mullowney, TRX Gold Chief Executive Officer. "Both pieces of work are cornerstones for the larger project development and help set the stage for the next big growth phase."

As previously announced by way of press release on December 12, 2022, highlights of the metallurgical drilling included:

• Hole BMMT015 intersected 28.0 m grading @ 10.68 g/t Au from 0 m;
• Hole BMMT020 intersected 123.0 m grading @ 2.69 g/t Au from 3 m;
• Hole BMMT009 intersected 121.0 m grading @ 2.96 g/t Au from 3 m;
• Hole BMMT022 intersected 106.0 m grading @ 4.19 g/t Au from 85 m, 77 m grading @ 3.09 g/t from 241 m; and
• Hole BMMT021 intersected 90.0 m grading @ 1.56 g/t Au from 139 m.
  

Results from both the metallurgical and geotechnical programs are expected by end of Q4 2023.

The Buckreef Gold property consists of a 16 km² land package located along the prolific Lake Victoria Greenstone Belt in the Geita region of Tanzania, approximately 110 km from the city of Mwanza and about 45 km to the west of Barrick Gold's Bulyanhulu gold mine (196,000 oz in 2022) and nearly 35 km south from AngloGold Ashanti's flagship Geita mine (521,000 oz in 2022).

The Buckreef Gold Mine has been operating since late 2021 and in the last 12 months, has undergone two successful mill expansions. In 2023, Buckreef Gold is expected to produce between 20,000 - 25,000 ounces at total average cash costs¹ of $750 - $850 per ounce, thanks to its high margin, open-pit nature. The TRX Gold team is currently working on a third mill expansion that is aimed at doubling current processing capacity, which is expected to positively impact the number of ounces produced in fiscal 2024.

In the long-term, the Buckreef Mine Development Project described above is aimed at growing the Buckreef Gold mining operation to a significant gold producer in the Tanzanian landscape.
