Buckreef Gold Commences Commissioning of Expanded Processing Plant

Expansion Expected to Increase Average Gold Production to an Initial 750-800 Ounces Per Month¹ at Anticipated Total Cash Costs² of US$725-825 Per Ounce Upon Final Commissioning

TORONTO, Oct. 20, 2021 -- Tanzanian Gold Corp. (TSX:TNX) (NYSE American:TRX) (TanGold or the Company) is pleased to provide an update on Buckreef Gold Company Limited's (Buckreef Gold) processing plant and the commencement of the commissioning phase of the new expanded processing plant by 360 tonnes per day (tpd). The Company and Buckreef Gold continue to advance the previously disclosed 1,000+ tpd operation.

During October, Buckreef Gold completed construction of the 360 tpd processing plant expansion. Buckreef Gold also continued to operate the 120 tpd processing plant subsequent to concluding the test period, which achieved a 90% gold recovery rate, as previously disclosed in September 2021. The existing 120 tpd processing plant has been integrated into the new processing plant circuit.

The new expanded processing plant construction was completed in line with the scheduled completion date of late September/October 2021 and within project capital expenditures guidance of US$1.3-1.6 million. This includes completion of all major construction activities associated with the processing plant expansion, including the ongoing execution of dry, cold and hot commissioning performance tests.

Highlights of Processing Plant Expansion:

• Low-Cost Expansion: $1.6 million in project capital expenditures to increase throughput by 360 tpd;
• Increased Gold Production: Expanded throughput expected to increase production to 750-800 ounces of gold per month¹ upon final commissioning and prior to construction of the 1,000+ tpd processing plant;
• Attractive Cost Profile: Total Cash Costs² expected to average US$725-825/oz;
• Improved Cash Flow: Operating cash flow from the expanded processing plant is anticipated to mitigate the negative cash flow from the testing period of the 120 tpd processing plant;
• Project Reinvestment: Anticipated cash flow generated from the larger plant will be reinvested in Buckreef Gold with a focus on: (i) exploration and drilling; (ii) enhanced CSR/ESG programs; and (iii) additional capital programs focused on growth and efficiencies;
• Short Expansion Timeframe: A five-month timeline from ordering the major components of the 360 tpd operation to the start of project commissioning in October 2021; and
• In-House Construction: The 360 tpd processing plant expansion was completed by the Buckreef Gold and TanGold teams in conjunction with key consultants/contractors, including: (i) Ausenco; (ii) Solo Resources; and (iii) CSI Energy Group. In-house execution resulted in an accelerated construction timeline which has enabled advanced production over initially envisioned timelines and the ability to maintain continuity of the workforce.
  

Stephen Mullowney, TanGold Chief Executive Officer commented: "The dedication and hard work of the Buckreef Gold and TanGold teams in the construction of the 360 tpd processing plant expansion is a very exciting milestone. The increased processing capacity is expected to allow us to advance the mine plan and increase near-term production in a cost-effective and efficient manner. The increased anticipated cash flow from the new larger plant will enable us to speed up the advancement of Buckreef Gold, including exploration at the Buckreef Main Zone, Buckreef West and Anfield Zone."

Buckreef Gold will continue with plans to advance a 1,000+ tpd operation while simultaneously operating the 360 tpd operation. The 1,000+ tpd operation is expected to be capable of producing 15,000 - 20,000 ounces of gold per year based on the initial mine plan and grade profile.

¹ The 360 tpd Plant estimates have not been prepared in accordance with the results of the Company's 2018 Prefeasibility Study, reflected in the Company's May 15, 2020 Updated Mineral Resource Estimate. The 18-Month mining plan which was utilized for the estimates are based upon an internal mine model reviewed by SGS Canada and cost inputs as validated by actual mining and processing costs from the 120 tpd test plant over the 9 months ended May 31, 2021. See 'Forward Looking Statements' at the end of this Press Release.
² 'Total Cash Cost' includes mine site operating costs such as mining, processing and local administrative costs, royalties, production taxes, mine standby costs and current inventory write downs, if any. Production costs are exclusive of depreciation and depletion, reclamation, capital and exploration costs. Total cash costs are net of by-product sales and are divided by gold ounces sold to arrive at a per ounce figure. Total Cash Costs is a non-IFRS financial performance measure often used in conjunction with conventional IFRS measures to evaluate performance. Total Cash Cost does not have a standardized meaning under IFRS and therefore may not be comparable to similar measures of performance disclosed by other issuers; it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
