Technology Metals Confirms High Recoveries from Gabanintha

THE BOURSE WHISPERER: Technology Metals Australia (ASX: TMT) received results of pilot plant scale roasting testwork of a bulk sample collected from within the North Pit region of the company’s Gabanintha vanadium project near Meekatharra in Wesertn Australia.

Technology Metals explained the bulk sample for the pilot plant scale testwork was collected from within the North Pit region of the Gabanintha project late last year.

A total of 14.2 tonnes of sample was collected from this program; consisting of a blend of transitional massive magnetite mineralisation, fresh massive magnetite mineralisation, transitional hanging wall banded mineralisation, fresh hanging wall banded mineralisation and fresh footwall banded mineralisation.

The pilot plant scale testwork using this bulk sample was designed to confirm optimal operating parameters and scalability of laboratory testwork results and provide data for vendor definition of design parameters and cost estimates for the ‘roasting’ section of the processing circuit.

Initial ‘sighter’ testwork was completed previous to this using a representative 300 kilogram sub-sample of the bulk sample that confirmed the very high purity of final vanadium pentoxide (V2O5) product that can be produced from the GVP, delivering a 99.36 per cent V2O5 product purity.

Samples of this material have been sent to potential end-users / offtake partners for independent verification.

The latest testwork was conducted by roasting kiln suppliers FLSmidth in Pennsylvania USA, confirming the very high vanadium solubility/recovery rates indicated from the previous laboratory and sighter scale testwork.

Rates ranged from 84.9 per cent to 90.7 per cent during continuous feed, confirming the 85 per cent solubility/recovery to be used in the Definitive Feasibility Study.

FLSmidth is now undertaking engineering design and cost estimates for the roasting section of the process circuit.

Technology Metals expects delivery of the DFS mid-2019, which will ultimately be determined by how long it takes to verify and incorporate this information in to the overall DFS model.

“The very important pilot scale testwork, a key component of the delivery of a high-quality Definitive Feasibility Study, has confirmed the very high recovery rates for the roasting section of the process circuit,” Technology Metals Australia managing director Ian Prentice said in the company’s announcement to the Australian Securities Exchange.

“Delivery of the kiln design and operating parameters from kiln experts FLSmidth is the next vital step to be completed.”
