Manindi Lithium Metallurgical Testwork Demonstrates High Lithium Recovery and Favorable Concentrate Grades

Highlights:

  • Metallurgical testwork and mineralogical characterisation completed on two composite samples of lithium mineralisation from the Manindi Project

  • Tests completed included semi-quantative XRD analysis, size fraction analysis, wet screen analysis, heavy liquid separation, magnetic separation and sighter flotation testing

  • Results indicate that Manindi lithium mineralisation principally occurs as lepidolite

  • Flotation tests produced concentrates with grade up to 3.05% Li2O and lithium recovery of up to 77% from 30% of the mass feed - additional upside exists on an optimised flowsheet tailored to the Manindi mineralisation

  • Concentrate grade and recovery compares favourably against other lepidolite hosted lithium projects

  • Low iron-oxide (Fe2O3) content confirms the Manindi lithium concentrate is a preferred product for potential end-users

  • Metals Australia to engage with lepidolite-hosted lithium concentrate end-users in China to further accelerate the exploration and development of the Manindi Lithium Project

  • Flotation tails contain significant tantalite mineralisation (Ta2O5) that could potentially also be recovered – provides additional upside to the potential economics of the project

  • Potential for further improvements in the metallurgical results given that the tests were scoping level in nature and that the flowsheet has not been optimised for the Manindi mineralisation

  • A reverse circulation (RC) percussion drilling program is planned to test the grade and continuity of lithium-bearing pegmatite dykes at Manindi – drilling to commence in the coming weeks

Diversified metals exploration company, Metals Australia Ltd (ASX: MLS ) is pleased to announce the results of preliminary metallurgical testing of lithium mineralisation at the Manindi Lithium Project (the “ Project ”), located in Western Australia.

Metallurgical consultants NAGROM were selected to undertake the testwork program on two composite diamond drill core samples collected from the Manindi Lithium Project in April 2018 (refer to ASX announcement dated 13 April 2018) . Testwork included sample preparation and compositing, semi-quantative XRD analysis, size fraction analysis, wet screen analysis, heavy liquid separation, magnetic separation and sighter flotation testing.

Mineral characterisation results indicate that the lithium mineralisation principally occurs as the mineral lepidolite. The metallurgical test work completed has indicated that flotation is the preferred option for treatment of the lithium mineralisation identified at Manindi. An un-optimised sighter flotation testing program achieved a concentrate grade of up to 3.05% Li2O and recovery of up to 77% with a mass yield of approximately 30%.

These concentrate grades and recovery profiles compare favorably against other lepidolitehosted lithium projects and are encouraging given that the flowsheet was not tailored to the mineralisation identified at Manindi.

As a comparison, indicative test work completed by Lithium Australia NL (ASX: LIT) on its Lepidolite Hill project located in Western Australia, produced a lepidolite-hosted lithium concentrate with a grade of 3.34% Li2O.

Commenting on the metallurgical test work results at Manindi, Mr Gino D’Anna, a Director of MLS

stated:

“This initial program of metallurgical test work on the lepidolite mineralisation identified at Manindi has provided the Company with some significant and highly encouraging results. Using an un-optimised flowsheet, the Company has demonstrated that the lithium mineralisation at Manindi is capable of producing a lithium concentrate of 3.05% Li2O which compares favorably against similar lepidolite-hosted lithium projects and meets the minimum benchmark for lepidolitehosted lithium concentrate end-users in China. The low-impurity of the lithium concentrate is another advantage of the lepidolite mineralisation at Manindi, and these results have been achieved with high recoveries of up to 77% with a mass yield of approximately 30%.

We are excited by what this initial program has delivered, and we remain committed to further exploring and developing this project, in line with our revised corporate strategy and alignment to the battery metals sector. Using these preliminary results, we can now confidently start to engage with potential end-users in China.

Metals Australia is planning to complete an RC percussion drilling program at Manindi that will test the grade, thickness and continuity of the lithium-mineralised pegmatite dykes that have already been identified at the Project.”

Manindi Lithium Project

The Manindi Lithium Project is located in the Murchison District of Western Australia, approximately 20 km southwest of the Youanmi gold mine. The Project is situated in a fertile geological complex and is host to a significant undeveloped zinc deposit. The Manindi Project is comprised of three granted mining leases.

Lithium-bearing pegmatite dykes have previously been identified on the Manindi mining leases in the vicinity of the Mulgara-Warabi Prospect areas (refer to Metals Australia ASX announcement dated 21 March 2017) .

Surface mapping carried out at Mulgara and Warabi Prospects identified at least three lithium bearing pegmatites outcropping at surface with strike lengths of over 300 m and widths up to 2530 m (Figure 1).

Results from twelve rock chip samples collected from these pegmatites have returned high grade assays up to 2.84% Li2O. The pegmatites were sampled where exposed and mapping indicated that they extend under cover.

The figure below outlines the interpreted geology of the Mulgara-Warabi prospect areas that is the known location of the lithium mineralisation. Recent reconnaissance mapping undertaken by the Company has suggested that the pegmatite dykes remain open to the east and to the west, depending on the pegmatite being mapped. This provides the Company with significant upside to demonstrate a potentially mineable mineralised envelope.

Metallurgical Testwork

Mineral processing consultants NAGROM based in Perth, Western Australia were selected by the Company to complete preliminary metallurgical testwork and mineralogical characterisation on the two composite samples of lithium mineralisation collected from the Project.

The testwork undertaken was broad in scope and comprised:

  • 1) Sample preparation and compositing;

  • 2) Semi-quantative XRD analysis;

  • 3) Size fraction analysis;

  • 4) Wet screen analysis;

  • 5) Heavy liquid separation (HLS);

  • 6) Magnetic separation; and

  • 7) Sighter flotation testing.

The testwork parameters were selected in order to provide the Company with basic metallurgical information about the mineralisation at Manindi and demonstrate that the lithium-bearing pegmatite rocks have mineralogical and metallurgical characteristics suitable for the production of a commercial concentrate.

Metallurgical Testwork Methods and Results

Two samples of half NQ size diamond drill core containing lithium-bearing pegmatite, weighing a total of approximately 50.7 kg, were supplied to NAGROM. The two samples were stage-crushed and composited in preparation for metallurgical testing and chemical and mineralogical characterisation.

The representative head samples of the two composites extracted during sample preparation were subjected to chemical analysis for a suite of elements. The assay grades of the two composite samples is shown in Table 2 below.

The tantalum potential of the mineralisation at Manindi had previously not been taken into consideration, however, at the composite assay grades of 140 ppm Ta2O5 and 300 ppm Ta2O5 respectively, the tantalum mineralisation provides additional upside to the potential economics of the project.

Composite
Sample ID
Li2O (ppm) Ta2O5 (ppm)
MND018 12,490 140
MND022 10,540 300

Samples of the composites were supplied to Microanalysis Australia for semi-quantative X-Ray Diffraction (XRD) analysis. Mineralogical examination of the feed samples by XRD determined that the lithium mineralisation primarily occurs as the mineral lepidolite, associated with typical pegmatite minerals.

The results are provided below in Table 3.

Mineral MND018 MND022
Muscovite 30% 29%
Quartz 27% 24%
Feldspar (albite) 26% 33%
Lepidolite 15% 13%
Chlorite 2% 1%
Beryl Trace Trace
Other Trace Trace

After crushing of the samples, assay of different size fractions indicated that the lithium does not preferentially concentrate into a particular size fraction. Tantalum (Ta2O5), which was identified as being of potential economic value, preferentially reported to fine grained material. This is an encouraging result and will help determine the most appropriate size fraction for the overall concentrate crush grain size.

Heavy liquid separation (HLS) and magnetic separation tests indicated that very little segregation of lithium mineralisation was being achieved.

However, sighter flotation tests showed that the lithium could be effectively recovered and that a concentrate grade of up to 3.05% Li2O with recovery of up to 77% lithium could be obtained, with a mass yield of approximately 30%. These results are illustrated in Table 4.

(%)

Recovery Li2O
(%)

Mass Yield
(%)
MND018 3.05 73.9 30.7
MND022 2.76 77.4 29.4

Results were considered to be very encouraging and positive given that the tests were completed using standard conditions and reagents, with no optimisation for the specific mineralisation at Manindi.

The fine-grained residue of the flotation process contained a significant proportion of the tantalite, so the process could also be optimised for its recovery.

Discussion of Results

Metallurgical testwork has successfully demonstrated that flotation is an effective processing method for the lithium mineralisation at the Manindi Lithium Project. The grade and recovery of the lithium is considered positive for a lepidolite concentrate, particularly as no optimisation of the process has been undertaken.

Further Work

The metallurgical testwork described above is a preliminary test program of the mineralisation at the Manindi Project and the composite samples are not considered to be representative of the overall lithium deposit due to their limited size and spatial distribution.

The Company’s consultants have made recommendations for future testing to (1) ensure representivity of a potential future mill feed; (2) optimise the process for the specific mineralisation at the Manindi Project; (3) evaluate recovery of the tantalum in the mineralisation; and (4) evaluate comminution characteristics of the mineralisation.

A reverse circulation (RC) percussion drilling program is planned to test the grade, thickness and continuity of graphite mineralisation at the Manindi Project. Further samples may be taken from this drilling to advance the metallurgical testwork and drilling of large-diameter core specifically for metallurgical characterisation will be considered.

Geology Deposit type, geological setting and style of mineralisation. The mineralisation at Manindi is hosted within an Archaean felsic and mafic volcanic
sequence. The sequence has been extensively deformed by regional metamorphism and
structural event related to the Youanmi Fault and emplacement of the Youanmi gabbro
intrusion and other later granitic phases.
The Manindi zinc-copper mineralisation is considered to be a volcanogenic massive
sulphide (VMS) deposit, comprising a series of lenses of zinc-dominated mineralisation that
have been folded, sheared, faulted, and possibly intruded by later dolerite and gabbro.
Pegmatite dykes that occur in the area are considered to be of the lithium-caesium-
