Stria Lithium’s Pontax Project Achieves Initial Results of 6.3% Li2O from Spodumene Concentrate with an 85% Overall Recovery after Metallurgical Testing
Supports the Viability of Pontax Spodumene as Feedstock for the Company’s Proprietary Process for Producing Lithium Metal and High Grade Lithium Compounds
May 24, 2016
OTTAWA – Stria Lithium Inc. (TSX-V: SRA) (“Stria” or the “Company”) is pleased to report metallurgical test results from bulk samples extracted from its wholly owned Pontax lithium project in Northern Quebec.
Stria President and Chief Operating Officer Iain Todd said the testing produced a surprisingly favourable result supporting the Company’s decision to continue its investigation and exploration of the Pontax property.
‘These initial test results confirm additional exploration is justified and the spodumene mineralisation at Pontax is a viable feedstock for our proprietary technologies for the recovery of lithium metal and high grade lithium compounds, ” said Dr. Todd.
The Company is focused on the phased development of its lithium property while concurrently aiming to generate early revenues from the manufacture of in-demand lithium products intended for next generation Lithium-Ion battery applications.
Towards its commercial goals, Stria has positioned itself as a partner in the 2GL Platform business alliance announced on May 18, 2016. (www.2GLPlatform.com).
Stria benefits from the integration of battery innovation from four leading critical materials development companies.
The Company holds the in-house developed and proprietary technologies that remove upstream obstacles to enable downstream production of lithium metal, lithium carbonate or hydroxide using conventional metallurgical processes.
The purpose of the metallurgical testing on 16.5 metric tonnes of spodumene mineralized material from the Pontax property, performed by SGS Canada Ltd. in Lakefield, Ontario, was intended to confirm the feasibility of Pontax’ spodumene mineralized material as a potential supply source for Stria’s proprietary lithium production process.
Samples were processed by dense medium separation (DMS) with a feed size of -6.35+0.85mm to concentrate lithium minerals (primarily spodumene) and to reject silicate gangue minerals.
Initial dense media separation testing produced an intermediate spodumene concentrate assaying 5.9% Li2O with 47.9% lithium recovery. This intermediate spodumene concentrate was further upgraded to 6.4% Li2O using dry magnetic separation of the concentrate.
Material finer than 0.850 mm that could not be processed by dense media separation was combined with the dense media separation middlings to be further upgraded by flotation. Locked cycle flotation testing produced a spodumene concentrate assaying 6.1% Li2O with a 84% Li2O flotation recovery..
In summary, the combined dense media separation – magnetic separation – flotation flowsheet (based on the flotation locked cycle test results) produced a combined concentrate assaying 6.3% Li2O with an 85% overall lithium recovery.
A summer exploration/geophysical survey program is now planned at the Pontax site to further explore the overall breadth of the spodumene bearing host rock and to identify drill targets for a more extensive drilling program in 2017.
About Stria’s Proprietary Process
An initial roasting produces the β-spodumene used for Stria’s process. Within a closed loop containing chloride compounds, the β-spodumene is mixed in a proprietary process environment. Impurities including iron, magnesium, vanadium, chrome, aluminum and silicates are eliminated, producing a high-purity lithium chloride concentrate.
The unique advantage of Stria’s process is that it removes upstream obstacles to enable downstream production of lithium metal, lithium carbonate or hydroxide using conventional metallurgical processes.
Stria’s process obviates the need for additional, cost-heavy refinery steps, making it economically competitive.
Moreover, the process permits the recycling and repeated re-use of chemicals, returning them to the start of the process —using fewer chemicals results in lower costs and effectively lowers the process’s environmental footprint.
