Diversified metals exploration company, Metals Australia Ltd (ASX: MLS ) is pleased to announce the results of preliminary metallurgical testing of graphite mineralisation at the Lac Rainy Graphite Project (the “Project”), located in Quebec, Canada.
SGS Canada Inc. (SGS) were selected to undertake the testwork program on two composite graphite samples collected from the Lac Rainy Project in August 2017 (see ASX announcement dated 12[th] October 2017). Testwork included sample preparation, chemical and mineralogical characterisation of the feed samples, and batch cleaner flotation based on a flowsheet comparable with the process proposed for the nearby Lac Knife Graphite Deposit being developed by Focus Graphite Inc.
Testwork results indicate that a commercial graphite concentrate with very good concentrate grades and recoveries can be achieved from the graphite mineralisation at Lac Rainy. Open circuit graphite recovery up to 91.0% and combined concentrate grades of up to 96.7% total carbon (Ct) were achieved. This is a significant outcome and is very encouraging as these results were achieved using a non-optimised flowsheet and are based on the flowsheet for a separate (though geologically similar) deposit. Furthermore, as these characterisation samples were collected from surface, it is likely that they have a certain degree of oxidation. Unoxidised samples from deeper within a graphite deposit often provide a better metallurgical performance.
Commenting on the metallurgical testwork results at Lac Rainy, Mr Gino D’Anna, a Director of MLS stated:
“These significant and highly encouraging results from SGS show that the graphite at Lac Rainy has the necessary grade and metallurgical characteristics to produce a commercial graphite concentrate, including that applicable to the battery industry. We were able to achieve a concentrate with recoveries of up to 91% at a grade of 96.7% Ct - this is an exceptional result for a first pass testing program. Given that the testwork was not optimised and based on the flowsheet from Focus Graphite Inc., which is publicly available, we believe that significant upside exists for the performance in future metallurgical processing testwork.
Metals Australia is planning to complete a diamond drilling program at Lac Rainy in early 2018 that will test the grade, thickness and continuity of the high grade graphite mineralisation that has already been identified at the project. This drilling will generate more representative unoxidised samples of graphite mineralisation that will provide an opportunity to better refine the flowsheet and metallurgical performance of the Lac Rainy mineralisation.”

Lac Rainy Graphite Project
The Lac Rainy Graphite Project is located in one of the premier graphite geological regions of Quebec. It sits approximately 20 km southwest of the historic iron ore mining town of Fermont in northern Quebec, and 260 km north-northeast of the city of Sept-Îles. The Lac Rainy Graphite Project is approximately 15 km east of Route 389, a paved highway which travels north to Fermont. The project comprises 86 mineral claims covering a total area of approximately 4,450 hectares. Lac Rainy is one of a number of projects held by the Company in Quebec (Figure 1).
The Project is located adjacent to property that hosts the Lac Knife Graphite Deposit owned by Focus Graphite (which is located less than 4 km south-west of the Project boundary) and hosts a Measured and Indicated Resource of 13.6 Mt @ 14.95% Cg and an Inferred Resource of 0.8 Mt @ 13.90% Cg at a 3.0% Cg cut-off (refer Focus Graphite TSX-V market announcement dated 6 March 2017).

Metallurgical Sample
In August 2017, the Company completed a channel sampling campaign and characterisation sample collection program at the Lac Rainy Graphite Project. Dahrouge Geological Consulting Ltd. were engaged to undertake the work (see ASX announcement dated 12[th] October 2017).
Surface samples at Lac Rainy have confirmed the presence of numerous high grade natural flake graphite mineralised occurences on the property. The samples, which were taken at and along strike immediately adjacent to the high grade Carheil Prospect in the eastern part of the claim block area, have outlined a high grade area of ~150 m strike length, within a larger mineralised strike of more than 2 km (Figure 3). When coupled with historic results, this sampling confirms that the Lac Rainy Project is highly prospective with significant potential to host a high grade deposit of natural flake graphite at substantial tonnage.
The channel sample composites used for mineralogical characterisation and metallurgical testing were collected from two sites along the Carheil Trend (Table 1), with a total combined weight of approximately 120 kg. The samples were excavated from a surface outcrop, with care taken to clean the exposure of soil and vegetation and to remove a layer of weathered material.

Metallurgical Testwork
SGS Canada Inc. (SGS) based in Lakefield, Ontario were selected by the Company to complete initial metallurgical testwork and mineralogical characterisation on the two composite samples of graphite mineralisation collected from the Project. The following sections include excepts, tables, and charts from the metallurgical test report provided by SGS Minerals titled “ The Scoping level Evaluation of Two Samples form the Lac Rainy Graphite Prospect ” and dated January 11, 2018.
The primary objectives of the program were to determine the metallurgical response of the samples and to characterise the graphite concentrate in terms of flake size distribution and total carbon grades of different size fractions.
The testwork comprised:
-
1) Sample preparation;
-
2) Sample characterisation (chemical and mineralogical); and
-
3) Flotation testing.
The testwork parameters were selected in order to provide the Company with basic metallurgical information about the mineralisation at Lac Rainy and demonstrate that the graphite had mineralogical and metallurgical characteristics suitable for the production of a commercial concentrate. A flowsheet based on publically available information for the nearby Lac Knife Graphite Deposit was selected as the initial conditions for the testwork.
Testwork Methods and Results
SAMPLE PREPARATION
Two composite samples of the Lac Rainy graphite mineralisation (sample numbers 129076 and 129077) weighing a total of approximately 120 kg were supplied to SGS. The two composite samples were prepared for metallurgical testing and chemical and mineralogical characterisation.
SAMPLE CHARACTERISATION
The representative head samples of the two composites extracted during sample preparation were subjected to chemical analysis.
The total carbon assays of the samples indicate high grades of 36.5% Ct and 22.0% Ct for samples 129076 and 129077, respectively (Table 2). Similarly, the graphitic carbon grades of the samples were high at 35.1% Cg and 21.7% Cg, respectively. Sulphur contents of sample 129076 was very low at 0.23% S, while sample 129077 contained 6.57% S. The latter result was confirmed by mineralogical examination (see below) that showed sample 129077 contains significantly more pyrite than sample 129076.

Mineralogical examination of the feed samples included optical mineralogy in transmitted and reflected light to determine the occurrence of graphite and its association with gangue minerals. The main conclusions of the analysis are that:
-
1) Graphite in both samples has a bimodal grain size distribution; it occurs both as fine-grained variably locked in non-sulphide gangue minerals, and as relatively coarse particles (<2 mm) that occur as liberated or intergrowths with non-sulphide gangue.
-
2) Graphite liberation is considered low at this grind (-6 mesh). Liberation is expected to vary and will reflect the proportion of coarse and fine-grained graphite. Intergrowths of graphite with other minerals are simple to moderately complex and should liberate well upon the proper grind target (<500 μm).
-
3) A main mineralogical difference between the samples is that sample 129077 contains significant pyrite, while sample 129076 does not.
FLOTATION TESTING
Two open circuit cleaner tests were carried out on each of the two composites. The first test employed the flowsheet that was presented in the feasibility study of Focus Graphite’s Lac Knife project, which is depicted in Figure 4.

The second set of tests included a finer classification of the intermediate concentrate at 80 mesh instead of 48 mesh and stirred media mills instead of polishing mills in the secondary cleaning circuits. This alternative grinding mill tends to be more effective when dealing with interlayered graphite.

Metallurgical Testwork Results
The open circuit carbon recovery was between 85.6% and 91.0% in the four tests. Tests using the base case Lac Knife flowsheet (tests F1 and F2) produced combined concentrate grades of 96.4.0% Ct for the 129076 composite and 87.9% Ct for the 129077 composite. The circuit modifications that were carried out (tests F3 and F4) produced a grade improvements to 96.7% C(t) and 95.8% C(t) for the 129076 and 129077 samples, respectively. These results are encouraging given that the test program was not optimised for the Lac Rainy Project.
In order to determine the flake size distribution and total carbon grades of the various flake sizes, the final cleaner concentrates were subjected to a size fraction analysis. The mass recovery and total carbon grades of the various size fractions are depicted in Figure 5 and Figure 6, respectively.

Discussion of Results
Metallurgical testwork has successfully demonstrated that a commercial graphite concentrate grade and recovery can potentially be achieved from the current characterisation samples collected at the Lac Rainy Project.
Composite sample 129076 outperformed composite sample 129077 in terms of concentrate grade, recovery and flake size distribution. Metallurgical testing yielded a combined concentrate grade of 96.4% Ct for the baseline test using the Lac Knife test conditions that are available in the public domain. The second test on this composite material with the modified flowsheet conditions produced a combined grade of 96.7% Ct. The second test also produced a higher mass recovery into the large and jumbo flake categories.
Composite sample 129077 yielded a lower head grade of 22.0% Ct and also proved harder to upgrade. The baseline test produced a concentrate grade of 87.9% Ct and the test with modified flowsheet conditions increased the concentrate grade increased to 95.8% Ct.
Based on the information obtained for the two sample composites, the testwork results are considered encouraging given that the material was tested using an existing, non-optimised flowsheet. A flowsheet based on publicly available information for the nearby Lac Knife Graphite Deposit was selected as the initial conditions for the testwork and further scope for optimisation remains, indicating that significant upside exists in the performance of the graphite mineralisation in future testing.
Characterisation samples used for the testwork were collected from surface exposures and, although fresh material was targeted, the samples collected may still have been partially oxidised, due to the outcropping nature of the graphite mineralisation. Oxidation, inherent to surface samples, is a hinderace in graphite processing, with performance typically improving with the use of unoxidised samples.
Further Work
The metallurgical testwork described above is a preliminary test program of the mineralisation at the Lac Rainy Project and the composite samples are not considered to be representative of the overall graphite deposit due to their limited size and spatial distribution. Furthermore, the tested samples were collected from the surface and are likely to be affected by oxidation to some degree.
SGS have made recommendations for future testing to 1) ensure representivity of a potential future mill feed; 2) take account of the specific mineralisation of the Lac Rainy Project; 3) evaluate comminution characteristics of the mineralisation; and 4) assess the environmental risk of the flotation tailings.
A diamond drilling program is planned to test the grade, thickness and continuity of graphite mineralisation at the Lac Rainy Project during the winter drilling season in Quebec. It is expected that this drilling will provide more representative and unoxidised mineralised samples that may be amenable for further metallurgical testwork to address these recommendations. A future program of large-diameter coring specifically for metallurgical characterisation will also be considered, depending on results.

| Data aggregation methods |
| In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. |
No weighted averages or data aggregation applied. No metal equivalents reported. |
|
| | Where aggregate intercepts incorporate short lengths of high grade results and longer | |||
| lengths of low grade results, the procedure used for such aggregation should be stated | ||||
| and some typical examples of such aggregations should be shown in detail. | ||||
| | The assumptions used for any reporting of metal equivalent values should be clearly | |||
| stated. | ||||

If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
True widths not known as the geometry of the graphitic zones had not been determined by drilling. However, units are considered to be generally dipping sub-vertically. |

| Balanced reporting |
| Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
Full and representative reporting of relevant results. | |

The metallurgical testwork described in the report is a preliminary test of the mineralisation at Lac Rainy and the composite samples are not considered to be representative of the overall graphite deposit due to their limited size and spatial distribution. Furthermore, as they |
| commercially sensitive. | are samples collected from surface they are likely to be affected by oxidation to some degree. | ||
| A diamond drilling program is planned to test the grade, thickness and continuity of graphite | |||
| mineralisation at the Lac Rainy project during the upcoming winter drilling season in | |||
| Quebec. It is expected that this drilling will provide more representative and unoxidised | |||
| mineralised samples that may be amenable for further metallurgical testwork. A future | |||
| program of large-diameter coring specifically for metallurgical characterisation will also be | |||
| considered, depending on results. |
