TORONTO, June 9th, 2021 (GLOBE NEWSWIRE) - Tanzanian Gold Corporation (TSX:TNX) (NYSE American:TRX) (TanGold or the Company) (operating through its wholly owned subsidiary in Tanzania) and its joint venture partner, The State Mining Company (STAMICO), announces that it has received updated and highly favourable metallurgical test results from the sulphide component of the Buckreef Gold Mine (Buckreef Gold) mineral resource.

As previously disclosed, SGS Canada Inc. (SGS) was retained to complete initial metallurgical test work at their Lakefield, Ontario facility on the sulphide component of the mineral resource, this work is now complete. As part of the study, three diamond core samples taken from the fresh rock (‘sulphide’ mineral resource) of the Buckreef Gold deposit (see figure on the subsequent page) were submitted to SGS for the study.

SGS will now be commissioned to undertake the metallurgical variability phase for Buckreef Gold which will encompass the first 5-7 years of production from the sulphide operation at Buckreef Gold. SGS has reviewed the information in the press release.

Study Highlights (Based on Samples Submitted)

The following intercepts and gold recoveries have been confirmed in the report:
MC01: 0.54 g/t Au over 78.88m – 94.1%
MC02: 19.4 g/t Au over 27.99m – 95.4%
MC03: 1.71 g/t Au over 52.53m – 85.3%
A straightforward flowsheet consisting of:
Primary grinding to P80 = ~100-150 µm
Rougher flotation
Regrind of the rougher concentrate to ~15-20 µm (P80)
Cyanide leaching of the reground flotation concentrate.
Cyanide leaching of the flotation tailing
Cyanide leaching of the flotation tailing
No refractory association of gold with arsenic sulphide was detected
Clean tailings, high probability of mine tailings not being acid generating
Further opportunities to improve gold extraction from MC03 have been identified through diagnostic leach testing
Mr. Stephen Mullowney, CEO (TanGold) commented, “The final initial metallurgical report confirms and adds to the positive metallurgical findings disclosed in February. We were very pleased with the recommended straightforward flowsheet and the fact that the samples tested did not exhibit any preg-robbing or other refractory characteristics. The samples were also not acid generating, confirming our approach of dry stack tailings going forward, which is much more environmentally friendly versus wet tailings. We look forward to working with SGS on variability testing for the sulphide feasibility study.”

Further Details of Test Work

In 2020, three diamond drill holes were completed for the purposes of initial, modern era metallurgical test work. Diamond drill hole details are tabulated below:

Chart of Buckreef Main Metallurgy Samples
The samples were extracted as fresh drill core from areas/zones with known lithologies from within the current projects open pit limit. The samples were selected by TanGold and confirmed by the SGS geological services group that worked together doing the metallurgical sample selection. The investigation included ore characterization, comminution, mineralogy, head analyses, and potential for gold preg-robbing, and evaluated the amenability of the three samples to two primary processing flowsheet options, that incorporate comminution (crushing and grinding), gravity separation, flotation and cyanidation unit operations.

About Tanzanian Gold Corporation

Tanzanian Gold Corporation along with its joint venture partner, STAMICO is building a significant gold project at Buckreef in Tanzania that is based on an expanded Mineral Resource base and the treatment of its mineable Mineral Reserves in two standalone plants. Measured Mineral Resource now stands at 19.98MT at 1.99g/t gold containing 1,281,161 ounces of gold and Indicated Mineral Resource now stand at 15.89MT at 1.48g/t gold containing 755,119 ounces of gold for a combined tonnage of 35.88MT at 1.77g/t gold containing 2,036,280 ounces of gold. The Buckreef Project also contains an Inferred Mineral Resource of 17.8MT at 1.11g/t gold for contained gold of 635,540 ounces of gold. The Company is actively investigating and assessing multiple exploration targets on its property. Please refer to the Company’s Updated Mineral Resources Estimate for Buckreef Gold Project, dated May 15, 2020, for more information.

Tanzanian Gold Corporation is advancing on three value-creation tracks:

1. Strengthening its balance sheet by expanding near-term production to 15,000 - 20,000 oz. of gold per year from the processing of oxide material from an expanded oxide plant.
2. Advancing the Final Feasibility Study for a stand-alone sulphide treating plant that is substantially larger than previously modelled and targeting significant annual gold production.
3. Continuing with a drilling program to further test the potential of its property, Exploration Targets and Mineral Resource base by: (i) identifying new prospects; (ii) drilling new oxide/sulphide targets; (iii) infill drilling to upgrade Mineral Resources currently in the Inferred category; and (iv) a step-out drilling program in the Northeast Extension.
