HIGH PURITY +99.5% V2O5 PRODUCT CONFIRMED AT GABANINTHA

ASX Announcement 12 September 2018

HIGHLIGHTS 

  • PRODUCT GENERATION WORK DELIVERS HIGH PURITY 99.53%1 V2O5. 
  • SUB-SAMPLES OF FINAL PRODUCT DISPATCHED TO A RANGE OF POTENTIAL VANADIUM END-USERS. 
  • TESTWORK CONFIRMS GABANINTHA MINERALISATION WELL SUITED TO PRODUCE HIGH QUALITY PRODUCT USING CONVENTIONAL SALT ROAST / WATER LEACH PROCESSING. 
  • DEFINITIVE-FEASIBIITY STUDY MAKING SIGNIFICANT PROGRESS AND IS ON TRACK TO BE DELIVERED IN JUNE QUARTER 2019.

BACKGROUND 

Technology Metals Australia Limited (ASX: TMT) (“Technology Metals” or the “Company”) is pleased to provide an update on metallurgical testwork activities at its Gabanintha Vanadium Project (“Gabanintha” or “Project”). The initial production generation testwork, involving the precipitation of ammonium metavanadate and subsequent generation of high purity V2O5 product from a ~60kg composite sample of high grade massive magnetite mineralisation, has now been completed.

This work has delivered a V2O5 product with a purity of 99.53% from an ammonium metavanadate precipitate that recovered >98% of vanadium from a leach solution generated from salt roasting of the magnetic concentrate from Gabanintha.

This work further confirms that the wholly owned Gabanintha deposit is amenable to producing very high purity V2O5 using conventional salt roast / water leach processing, with relatively low reagent consumption and without the requirement of additional costly contaminant removal steps. Both the solution and final product produced from this testwork are regarded as extremely clean and low in solution impurities.

Gabanintha hosts an Ore Reserve of 16.7 Mt at 0.96% V2O5, contained within an Indicated Mineral Resource of 21.6 Mt at 0.9% V2O5 in the Northern Block. Ongoing drilling as part of the DFS is focused on expanding the Indicated Mineral Resource within the current Global Mineral Resource estimate of 119.9 Mt at 0.8% V2O5 and 9.7% TiO2.

Managing Director Ian Prentice commented; “To achieve greater than 99.5% purity of V2O5 product from this phase of testwork is a very exciting achievement for the Company and I look forward to presenting these results to interested parties during my current visit to China”

METALLURGICAL TESTWORK – PRODUCT GENERATION 

A program of metallurgical testwork designed to generate final product for end-users has been completed under the supervision of the Company’s metallurgical consultant METS Engineering Group Pty Ltd (“METS”). This round of testwork was based on representative samples of the high grade massive magnetite zone from the diamond drilling completed in the 2017 drilling campaign.

Testwork has definitively shown that magnetic concentrates produced from all zones of the massive magnetite and the fresh disseminated magnetite are amenable to conventional salt roast / water leach processing. The magnetic concentrates delivered very high vanadium recoveries and rejection of gangue minerals from the high grade fresh and transition material and the disseminated medium grade fresh material. Vanadium grades reporting to the magnetic concentrate ranged from 1.27 to 1.34% V2O5 for these ore types, with weight recoveries ranging from 85.6% for the massive high grade fresh composite to 33% for the disseminated medium grade fresh composite.

Previous downstream processing testwork confirmed the high quality of the Gabanintha ore, delivering final V2O5 product with a purity in excess of 99% (see ASX announcement dated 31 May 2018).

The recently completed product generation testwork, conducted by ALS Metallurgy Services, used approximately 60kg of combined transitional and fresh high grade massive magnetite mineralisation, which generated approximately 49kg of magnetic concentrate after being processed through triple pass LIMS at 1200 Gauss. The composited magnetic concentrate was batch salt roasted, with the resultant calcine product water leached to ensure complete dissolution of sodium vanadate to the leach solution.

The leach solution containing the vanadium was then subjected to desilication, generating a cleaner ammonium metavanadate (AMV) feed solution than the previous downstream processing testwork. AMV precipitate was filtered from this feed solution, with >98% of the vanadium recovered in to a high purity precipitate. The AMV precipitate was then calcined to generate a final V2O5 product (see Figure 1), with a calculated purity of 99.53% based on the sum of impurities method. Impurities within the final V2O5 consist of a small volume of alumina, chromium, copper, potassium and magnesium.

GABANINTHA DFS UPDATE

ASX Announcement 7 September 2018

HIGHLIGHTS 

  • STAGE 1 DRILLING COMPLETED AT NORTH PIT AREA. 
  • ALL HOLES INTERSECTED BROAD ZONES OF HIGH GRADE MASSIVE MAGNETITE MINERALISATION AT DOWN HOLE DEPTHS OF UP TO 195M. 
  • DRILLING HAS CONFIRMED THE VERY SHALLOW OXIDATION PROFILE PROVIDING EARLY ACCESS TO HIGH YIELDING HIGH GRADE MINERALISATION AND POTENTIAL FOR STEEPER PIT WALLS. 
  • ACQUIRED THE 1.5% NET PROFIT INTEREST OVER E51/1510 AND P51/2785, THE TENEMENTS THAT COVER THE PROPOSED NORTH PIT AND PROJECT INFRASTRUCTURE. 
  • THIS ACQUISITION IS VERY POSITIVE FOR THE FUTURE DEVELOPMENT AND ECONOMICS OF THE PROJECT.

BACKGROUND 

Technology Metals Australia Limited (ASX: TMT) (“Technology Metals” or the “Company”) is pleased to provide an update on progress of the definitive feasibility study (“DFS”) at its Gabanintha Vanadium Project (“Gabanintha” or “Project”).

Stage 1 drilling has been completed in the North Pit area, consisting of 9 holes for a total of 1,659m, divided in to 521m of RC drilling and 1,138m of diamond drilling. Holes targeted the depth extension of the Mineral Resource, provided geotechnical data for the proposed open pit walls and generated additional sample for metallurgical testwork.

The Company has also completed the acquisition of the 1.5% net profit interest (“Royalty”) over E51/1510 and P51/2785, the tenements that cover the proposed North Pit and associated supporting infrastructure. The consideration for the acquisition consists of fully paid TMT shares upon the satisfaction of a number of milestones. The acquisition of the Royalty is very positive for the future development, and enhances the economics, of the Project.

The DFS has made significant progress since formal commencement on Tuesday 31 July 2018, maintaining the momentum and focus generated through the delivery of the pre-feasibility study.

Managing Director Ian Prentice commented; “The stage 1 drilling data has confirmed our belief in the importance of the North Pit in the overall development of the Gabanintha Vanadium Project, with the acquisition of the Royalty over this area very positive for the planned development of this globally significant vanadium project”.

PROJECT ENHANCEMENT OPPORTUNITIES 

A number of significant opportunities have been identified to enhance the results of the Project prefeasibility study (PFS), including 

  • Upgrading more of the Inferred Mineral Resources to the Indicated category, thereby increasing the mine life; 
  • Conducting a detailed geotechnical assessment, focussed on the footwall of the designed pits, allowing steeper pit walls and significantly reducing the overall strip ratio; and 
  • Optimising the open pit mine scheduling to ensure maximum financial returns with staged open pit development and early access to higher yielding ore.

The stage 1 drilling program, which consists of approximately 6,600m of drilling across the Northern Block of tenements and the Southern Tenement, is designed to provide the initial data in support of the Project enhancement opportunities.

STAGE 1 DRILLING PROGRAM 

The stage 1 drilling program is progressing well, with all stage 1 holes now completed in the North Pit area (see Figure 1). This drilling consisted of 9 holes for a total of 1,659m, divided in to 521m of RC drilling and 1,138m of diamond drilling.

This program is designed to: 

  • extend the Northern Block Mineral Resource estimate both along strike and at depth to increase the overall resource size and the Indicated Mineral Resource category / Probable Reserve estimate (see Figure 1); 
  • upgrade, and convert part of, the Southern Tenement Inferred Mineral Resource estimate to the Indicated Resource category; 
  • provide geotechnical data, in particular for the footwall portions of the designed pits, to provide sufficient data to enable a steepening of the designed open pit walls, thereby dramatically decreasing the overall strip ratio; and 
  • generate additional diamond core sample for the ongoing metallurgical testwork program, including the generation of final product to be provided to potential vanadium end-users.

All holes targeting the depth extension of the Mineral Resource estimate in the North Pit area intersected broad zones of massive magnetite mineralisation, with down hole depths of up to 195m to the top of the mineralisation. Geotechnical data is being collected for each of the holes completed in the North Pit area, with eight (8) holes intersecting the footwall zone and one (1) hole drilled in to the western proposed pit wall area. Drilling in the North Pit area has confirmed the previously identified very shallow oxidation profile, which has positive implications for early access to higher yielding high grade mineralisation and the potential for steeper pit walls than included in the pre-feasibility study (“PFS”) proposed open pit designs.

Drilling is continuing in the Central Pit area (see Figure 1) and in the Southern Tenement. The RC drilling component of the stage 1 program is on track to be finished by mid September, with the diamond drilling component expected to be completed in late September.

Preliminary assessment of the geotechnical data from drilling in the North Pit is expected to be available in mid to late September, with initial assay results from the North Pit area RC drill holes expected to be available in October 2018.

SUMMARY 

During the June 2018 Quarter the result of the pre-feasibility study (“PFS”) on the development of the Gabanintha Vanadium Project was announced, confirming the Project to be a high value, relatively low risk and technically strong development opportunity. The PFS was based on the Indicated Mineral Resource of 21.6 Mt at 0.9% V2O5 in the Northern Block of tenements out of a global Indicated and Inferred Mineral Resource of 119.9 Mt at 0.8% V2O5. The PFS mining and production schedule of 19.2 Mt at 0.96% V2O5 includes 13% Inferred Mineral Resources and a mine plan based on the development of two open pits; the North Pit and the Main Pit.

It is anticipated that the Project production profile will ramp up to approximately 13,000 tpa high purity (+99%) V2O5 delivering a rapid capital payback of about 2.5 years from commencement of commissioning (including a six (6) month ramp up period). The Project delivers an anticipated pre-tax NPV in the region of $1,277 million over a projected 13 year mine life, with an IRR of 55%, and an estimated life of mine operating costs of US$4.27/lb V2O5. These project metrics compare very favourably to global peers.

Given these outcomes, the Board has resolved to proceed immediately with the commencement of a Definitive Feasibility Study (“DFS”).

The PFS also enabled the estimation of a maiden Probable Ore Reserve for the Project of 16.7Mt at 0.96% V2O5, representing a very high +77% tonnage conversion from Indicated Resource.

Downstream processing testwork has confirmed the Gabanintha ore as being amenable to conventional salt roast / water leach processing, delivering a final V2O5 product with a purity in excess of 99%. The solution produced from the leaching testwork is regarded as extremely clean and low in solution impurities. A larger composite sample is currently being processed with the aim of generating final product to be provided to potential vanadium end-users.
