TORONTO, Feb. 14, 2020 (GLOBE NEWSWIRE) -- Tanzanian Gold Corporation’s (TSX:TNX) (NYSE American:TRX) (the “Company’s”) Board of Directors is pleased to announce Unclassified Mineral Resources for the 1.2km long Buckreef Shear Zone that amount up to 4,291,000 ounces contained in 242.4 million tons grading at 0.57 g/t Au at a block cutoff grade of 0.1 g/t Au. The Unclassified Mineral Resources are from an unconstrained block model using all the drilling results to date. Results at higher cut-off grades are shown in the table below.
As a consequence of the drilling program the Company completed in 2019, the largest drilling campaign in the Company’s history amounting to over 17,650m in 60 holes during which a significant number of exploration targets were identified which require further drilling to upgrade the gold mineralization encountered in these exploration areas to the Inferred category.
Further, as the gold mineralization in the Buckreef Shear Zone is still open along strike to the northeast and down dip a Phase III drilling program has been started to further test the continuity of the mineralization at ultra-deep levels below mineralization encountered in Phase II.
And finally, the new global estimate of Mineral Resources in the Buckreef Shear Zone was derived from a new resource model developed for the Company that combines geological information such as major rock units, structures, alteration styles and assay data from over 1,000 holes that amounted to approximately 140,000m that were drilled along the Buckreef Shear Zone. The new model includes holes drilled by previous owners of Buckreef as well as holes drilled by the Company since it acquired Buckreef in 2011; and includes the results from the drilling campaign in 2019.
In view of these considerations, the Company has elected to, in the first instance, give these unconstrained Resource estimates the designation of Unclassified – Exploration Targets. A NI 43-101 Technical Report will be released in 45 days by Virimai Projects as part of the continuation of the results reported in the Pre-Feasibility Report published in June 2018. This estimate will culminate Estimated Mineral Resources categorized into Measured, Indicated and Inferred Resources.

Sample Protocol and QA/QC
The sample chain of custody is managed by the Buckreef technical team under the supervision of Anthony Minde. Gold analyses reported in this release were performed by standard fire assay using a 50-gram charge with atomic absorption finish (0.01ppm LLD) and a gravimetric finish for assays greater than 10 grams per tonne. All assays were performed by Nesch Mintech Laboratory in Mwanza. Sampling and analytical procedures are subject to a comprehensive quality assurance and quality control program. The QAQC program includes duplication to the samples, blanks and analytical standards.
Intervals of core to be analyzed are split in half with a mechanized core cutter, with one half sent to the Laboratory for geochemical analysis and the remaining half kept in storage for future reference and uses.
Nesch Mintech Laboratory is ISO 90001 and 17025 accredited and employs a Laboratory Information Management System for sample tracking, quality control and reporting.

Virimai Projects have read and approved the contents of this press release and do hereby confirm that they are now actively engaged as the Qualified Person (QP) undertaking the NI43-101 Mineral Resource Update Technical Report following the completion of the two phases of resource upgrade drilling conducted as per their recommendations in the Pre-Feasibility report of June 2018.
Tanzanian Gold Corporation Executive Chairman, James Sinclair, commented “The numbers presented here today speak for themselves, and offer a first glimpse of some of the results of our year-long exploration and development program at Buckreef. This extensive and comprehensive program has been conducted with the most scientific of methods and at the highest of industry standards. This program would not be in place without critical, value added, financing completed in a year which has been fully transformational for our company. As we have said in the past, mines are not simply discovered – they are built. We will continue to build the Buckreef Mine toward the goal of world class status.”
