Studies Undertaken On Sulphide Component Of Buckreef Gold Project
Tanzanian Gold Corporation (TSX:TNX) and its joint venture partner, The State Mining Company (STAMICO), have received promising updated and highly favourable metallurgical test results from the sulphide component of the Buckreef Gold Mine mineral resource.
SGS Canada Inc. was retained to complete initial metallurgical test work at its 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.
SGS will now be commissioned to undertake the metallurgical variability phase for Buckreef Gold which will encompass the first five to seven years of production from the sulphide operation at Buckreef Gold.
The following intercepts and gold recoveries have been confirmed in the report:
o MC01:0.54 g/t Au over 78.88m – 94.1%
o MC02:19.4 g/t Au over 27.99m – 95.4%
o MC03:1.71 g/t Au over 52.53m – 85.3%
A straightforward flowsheet consisting of:
o Primary grinding to P80 = ~100-150 μm
o Rougher flotation
o Regrind of the rougher concentrate to~15-20μm(P80)
o Cyanide leaching of the reground flotation concentrate.
o Cyanide leaching of the flotation tailing
- No preg-robbing activity was detected
- 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
“The final initial metallurgical report confirms and adds to the positive metallurgical findings disclosed in February,” CEO, Stephen Mullowney, said.
“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.”
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.
