GSW-Tailings-Slurry and GSP-Tailings-Slurry Samples Generated in 2017 Pilot-Plant Programme in Brazil

NO. PAGES (including this page): 46 DATE: 28th January 2018 Steve, The analysis results for the GSW-tailings-slurry-water and GSP-tailings-slurry-water samples are presented in Table 1. The GSW-Tailings and GSP-Tailings corresponds to the treatment of Weathered-Ore-Composites, and Primary-Ore-Composites, respectively. The above tailings-slurry-water samples were sent from Brazil direct to SGS (Newburn, Perth) for analysis. The corresponding tailings-solids samples were initially sterilised by gamma-radiation treatment, and were then received at the GCA Testing Laboratory (Bridgetown, WA). These samples were immediately frozen for preservation, pending conducting testing until a later date. The samples were recently thawed and sub-samples taken for static testing with the remainder refrozen. Static testing of the GSW-tailings-solids and GSP-tailings-solids samples is currently in hand. Pertinent details of the metallurgical pilot-plant trial are presented in Attachment I.1 1 Although not indicated in Attachment I, trace amounts of diesel were added for the flotation step in the metallurgical trials.

1.0 ANALYSIS RESULTS FOR TAILINGS-SLURRY-WATER SAMPLES 1.1 Inorganic and Physical Chemistry 1.1.1 GSW-Tailings-Slurry-Water This tailings-slurry-water was circum-neutral (pH 7.3) with abundant bicarbonate-alkalinity (88 mg/L as CaCO3), and minor-element concentrations either below, or close to, the respective detection-limits (0.1-10 µg/L typically) [Table 1]. The above quality of the GSW-tailings-slurry-water sample accords with that expected based on the analysis of the water-extracts (for a solid:water ration of ca. 1:2 [w/w]) of the Low-Grade-Oxide-Ore samples tested in the GCA (2018) study.2 1.1.2 GSP-Tailings-Slurry-Water Ageing reactions have influenced the chemistry of the GSP-tailings-slurry-water sample (Table 1). The pH value of 3.7, and elevated concentrations in the mg/L-range for Al, Fe, etc. reflect acidification from sulphide-oxidation in tailings-slurry samples being stored for some time during the pilot-plant trials, as well as time (weeks) before being analysed at SGS (Newburn). The ex-mill tailings-slurry-water for the full-scale treatment of the Primary-Ores should have a pH of 7-8+ reflecting pH control for flotation. Although difficult to accurately predict, the concentrations of minor-elements should be below, or close to, the respective detection-limits (e.g. 0.1-10 µg/L range) for a slurry-water-pH of 7+. However, slurry-water-Se concentrations are anticipated to be within the low tens-of-µg/L range.3 2.2 Hydrocarbons The tailings-slurry-water samples were analysed for recoverable hydrocarbons (of different chain lengths from C6 to C36), volatile hydrocarbons, and polycyclic aromatic hydrocarbons (PAHs). The GSW-tailings-slurry-water sample had a C6-C14 fraction concentration of 270 µg/L, and a C15-C28 fraction concentration of 300 µg/L (Table 1). The GSP-tailings-slurry-water sample had a C6-C14 fraction concentration of 140 µg/L. The above fractions (viz. simple, straight-chain aliphatic hydrocarbons) chiefly reflect residual diesel components, since traces of diesel are used in ore flotation.

2 Reference: Graeme Campbell and Associates Pty Ltd, 2018, "Mount Dromedary Project: Geochemical Assessment of Mine-Waste and Low-Grade-Ore (LG-Ore) Samples – Implications for Mine-Waste and LG-Ore Management", unpublished report prepared for Novonix Limited. 3 It is noted that the recorded Se concentration of 1 µg/L for the GSP-tailings-slurry-water sample is likely biased 'on-the-low-side', due to enhanced sorption / precipitation of Se promoted by the elevated Fe concentrations, due to the acidification during 'ageing'.


3

All other analytes were either less than, or at, the respective method detection-limits (0.1-1 µg/L range) [Table 1]. 2.0 CLOSURE The above analysis results indicate that the GSW-tailings-slurry-water is essentially of potable quality, and reflects the expected benign nature of the Oxide/Weathered-Ores to be processed. Based on the testing of LG-Primary-Ore samples in the GCA (2018) study, the Primary-Ores to be processed should be typically Potentially-Acid Forming (PAF). However, with pH control during flotation, the slurry-water produced during Primary-Ore treatment should be circum-neutral with minor-element concentrations typically below detection-limits, save possibly for Se (e.g. Se concentrations may be within low tens-of-µg/L range). Analysis of 'freshly-produced/non-aged' samples would be required to more fully assess the quality of the primary-ore-tailings-slurry-waters. I trust the above is useful to your current needs.

In the actual treatment of GSP-Ores in the full-scale ill, the pH of the ex-mill tailings-slurry-water should be within the range 7-8+. At this pH the concentrations of Al, Fe, etc. should be below, or near, their respective-detection limits.

First lot received in December 2016 followed by the second lot received in March 2017.

Sample preparation:

1- Manually screening on 6.35 mm; 2- Oversize on 6.35 mm was crushed in a roller crusher until 100% the material

passed on 6.35 mm; 3- All crushed material was the raw material used to feed the pilot plant.

Metallurgical Teswork:

GSP tailings were produced and stored during the piloting plant testwork execution. Due to the lack of GSW sample available a shorter circuit was performed to produce the GSW tailings. Both flowsheets in diagram forms are shown below.

PE120485 R1QC SUMMARY

MB blank results are compared to the Limit of Reporting

LCS and MS spike recoveries are measured as the percentage of analyte recovered from the sample compared the the amount of analyte spiked into the sample.

DUP and MSD relative percent differences are measured against their original counterpart samples according to the formula : the absolute difference of the two results divided

by the average of the two results as a percentage. Where the DUP RPD is 'NA' , the results are less than the LOR and thus the RPD is not applicable.

METHOD METHODOLOGY SUMMARY

METHOD SUMMARY

pH in Soil Sludge Sediment and Water: pH is measured electrometrically using a combination electrode (glass plus

reference electrode) and is calibrated against 3 buffers purchased commercially. For soils, an extract with water is

made at a ratio of 1:5 and the pH determined and reported on the extract. Reference APHA 4500-H+.

AN101

Conductivity and TDS by Calculation: Conductivity is measured by meter with temperature compensation and is

calibrated against a standard solution of potassium chloride. Conductivity is generally reported as µmhos/cm or

µS/cm @ 25°C. For soils, an extract with water is made at a ratio of 1:5 and the EC determined and reported on

the extract, or calculated back to the as-received sample. Total Dissolved Salts can be estimated from conductivity

using a conversion factor, which for natural waters, is in the range 0.55 to 0.75. SGS use 0.6. Reference APHA

2510 B.

AN106

Total Dissolved Solids: A well-mixed filtered sample of known volume is evaporated to dryness at 180°C and the

residue weighed. Approximate methods for correlating chemical analysis with dissolved solids are available.

Reference APHA 2540 C.

AN113

Alkalinity (and forms of) by Titration: The sample is titrated with standard acid to pH 8.3 (P titre) and pH 4.5 (T titre)

and permanent and/or total alkalinity calculated. The results are expressed as equivalents of calcium carbonate or

recalculated as bicarbonate, carbonate and hydroxide. Reference APHA 2320. Internal Reference AN135

AN135

Determination of Fluoride by ISE: A fluoride ion selective electrode and reference electrode combination , in the

presence of a pH/complexation buffer, is used to determine the fluoride concentration. The electrode millivolt

response is measured logarithmically against fluoride concentration. Reference APHA F- C.

AN141

Nitrate and Nitrite by FIA: In an acidic medium, nitrate is reduced quantitatively to nitrite by cadmium metal. This

nitrite plus any original nitrite is determined as an intense red-pink azo dye at 540 nm following diazotisation with

sulphanilamide and subsequent coupling with N-(1-naphthyl) ethylenediamine dihydrochloride. Without the

cadmium reduction only the original nitrite is determined. Reference APHA 4500-NO3- F.

AN258

Ammonia by Continuous Flow Analyser: Ammonium in a basic medium forms ammonia gas, which is separated

from the sample matrix by diffusion through a polypropylene membrane . The ammonia is reacted with phenol

and hypochlorite to form indophenol blue at an intensity proportional to the ammonia concentration. The blue

colour is intensified with sodium nitroprusside and the absorbance measured at 630 nm. The sensitivity of the

automated method is 10-20 times that of the macro method. Reference APHA 4500-NH3 H.

Reactive forms of silicon in acid solution below pH 2 react with ammonium molybdate ions to form a yellow

silicomolybdate which is then reduced with ascorbic acid to produce a blue silicomolybdate complex. Oxalic acid is

added to destroy any molybdophosphoric acid. Colourimetric determination by Aquakem Discrete Analyser .

AN270

Chloride by Aquakem DA: Chloride reacts with mercuric thiocyanate forming a mercuric chloride complex. In the

presence of ferric iron, highly coloured ferric thiocyanate is formed which is proportional to the chloride

concentration. Reference APHA 4500Cl-

AN274

sulfate by Aquakem DA: sulfate is precipitated in an acidic medium with barium chloride. The resulting turbidity is

measured photometrically at 405nm and compared with standard calibration solutions to determine the sulfate

concentration in the sample. Reference APHA 4500-SO42-. Internal reference AN275.

AN275

Mercury by Cold Vapour AAS in Waters: Mercury ions are reduced by stannous chloride reagent in acidic solution

to elemental mercury. This mercury vapour is purged by nitrogen into a cold cell in an atomic absorption

spectrometer or mercury analyser. Quantification is made by comparing absorbances to those of the calibration

standards. Reference APHA 3112/3500.

METHOD SUMMARY

Determination of elements at trace level in waters by ICP-MS technique, in accordance with USEPA 6020A.AN318

Metals by ICP-OES: Samples are preserved with 10% nitric acid for a wide range of metals and some non-metals.

This solution is measured by Inductively Coupled Plasma. Solutions are aspirated into an argon plasma at

8000-10000K and emit characteristic energy or light as a result of electron transitions through unique energy

levels. The emitted light is focused onto a diffraction grating where it is separated into components .

AN320

Photomultipliers or CCDs are used to measure the light intensity at specific wavelengths. This intensity is directly

proportional to concentration. Corrections are required to compensate for spectral overlap between elements.

Reference APHA 3120 B.

AN320

Total Recoverable Hydrocarbons: Determination of Hydrocarbons by gas chromatography after a solvent

extraction. Detection is by flame ionisation detector (FID) that produces an electronic signal in proportion to the

combustible matter passing through it. Total Recoverable Hydrocarbons (TRH) are routinely reported as four

alkane groupings based on the carbon chain length of the compounds: C6-C9, C10-C14, C15-C28 and C29-C36

and in recognition of the NEPM 1999 (2013), >C10-C16 (F2), >C16-C34 (F3) and >C34-C40 (F4). Where F2 is

corrected for Naphthalene, the VOC data for Naphthalene is used.

AN403

Additionally, the volatile C6-C9/C6-C10 fractions may be determined by a purge and trap technique and GC/MS

because of the potential for volatiles loss. Total Recoveerable Hydrocarbons - Silica (TRH-Silica) follows the same

method of analysis after silica gel cleanup of the solvent extract. Aliphatic/Aromatic Speciation follows the same

method of analysis after fractionation of the solvent extract over silica with differential polarity of the eluent

solvents.

AN403

The GC/FID method is not well suited to the analysis of refined high boiling point materials (ie lubricating oils or

greases) but is particularly suited for measuring diesel, kerosene and petrol if care to control volatility is taken. This

method will detect naturally occurring hydrocarbons, lipids, animal fats, phenols and PAHs if they are present at

sufficient levels, dependent on the use of specific cleanup/fractionation techniques. Reference USEPA 3510B,

8015B.

AN403

SVOC Compounds: Semi-Volatile Organic Compounds (SVOCs) including OC, OP, PCB, Herbicides, PAH,

Phthalates and Speciated Phenols (etc) in soils, sediments and waters are determined by GCMS/ECD technique

following appropriate solvent extraction process (Based on USEPA 3500C and 8270D).

AN420

VOCs and C6-C9 Hydrocarbons by GC-MS P&T: VOC`s are volatile organic compounds. The sample is presented

to a gas chromatograph via a purge and trap (P&T) concentrator and autosampler and is detected with a Mass

Spectrometer (MSD). Solid samples are initially extracted with methanol whilst liquid samples are processed

directly. References: USEPA 5030B, 8020A, 8260.

Free and Total Carbon Dioxide may be calculated using alkalinity forms only when the samples TDS is <500mg/L.

If TDS is >500mg/L free or total carbon dioxide cannot be reported . APHA4500CO2 D.

Calculation


PE120485 R1

Samples analysed as received.

Solid samples expressed on a dry weight basis.

Where "Total" analyte groups are reported (for example, Total PAHs, Total OC Pesticides) the total will be calculated as the sum of the individual

analytes, with those analytes that are reported as <LOR being assumed to be zero. The summed (Total) limit of reporting is calcuated by summing

the individual analyte LORs and dividing by two. For example, where 16 individual analytes are being summed and each has an LOR of 0.1 mg/kg,

the "Totals" LOR will be 1.6 / 2 (0.8 mg/kg). Where only 2 analytes are being summed, the " Total" LOR will be the sum of those two LORs.

Some totals may not appear to add up because the total is rounded after adding up the raw values.

If reported, measurement uncertainty follow the ± sign after the analytical result and is expressed as the expanded uncertainty calculated using a

coverage factor of 2, providing a level of confidence of approximately 95%, unless stated otherwise in the comments section of this report.

Results reported for samples tested under test methods with codes starting with ARS -SOP, radionuclide or gross radioactivity concentrations are

expressed in becquerel (Bq) per unit of mass or volume or per wipe as stated on the report. Becquerel is the SI unit for activity and equals one

nuclear transformation per second.

Note that in terms of units of radioactivity:

a. 1 Bq is equivalent to 27 pCi

b. 37 MBq is equivalent to 1 mCi

For results reported for samples tested under test methods with codes starting with ARS -SOP, less than (<) values indicate the detection limit for

each radionuclide or parameter for the measurement system used. The respective detection limits have been calculated in accordance with ISO

11929.
