ASX RELEASE 8 APRIL 2021 ASX: JRL

UPGRADED MINERAL RESOURCE CONFIRMS McDERMITT AS THE LARGEST LITHIUM DEPOSIT IN THE USA

  • Combined Indicated and Inferred Mineral Resource Inventory of 1.43 Billion tonnes at 1,320ppm Li for total of 10.1 Million tonnes Lithium Carbonate Equivalent (LCE) at 1,000 ppm cut-off grade (COG)

  • At 10.1Mt LCE McDermitt is now the largest lithium deposit in the US by contained lithium in Mineral Resource[1]

  • The deposit remains open with an Exploration Target Range (ETR) between 1.3 to 2.3 Billion tonnes at 1,100 to 1,500 ppm Li

  • Jindalee is well funded to advance the development of the McDermitt Project with additional drilling, mining and metallurgical studies planned

Note that the potential quantity and grade of the Exploration Target is conceptual in nature, there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource.

Jindalee Resources Limited ( Jindalee , the Company ) is pleased to announce the updated Mineral Resource Estimate (MRE) at the Company’s 100% owned McDermitt Lithium Project (US) ( McDermitt ) following the completion of drilling in December 2020[9] .

McDermitt now hosts a combined Indicated and Inferred Mineral Resource Inventory of 1.43 Billion tonnes at 1,320ppm Li for total of 10.1 Million tonnes Lithium Carbonate Equivalent (LCE) at 1,000 ppm Li COG, making it the largest lithium deposit in the United States by contained lithium in Mineral Resource , eclipsing Lithium Americas’ (TSX: LAC) Thacker Pass deposit (8.3Mt LCE at 2,000ppm Li COG)[1] .

Table 1 – Summary of McDermitt Mineral Resource Estimate at varying cut-off grades, with preferred reporting cut-off of 1,000ppm highlighted. Note: totals may vary due to rounding.

The cut-off grade for reporting of the Mineral Resource has reduced from 1,750ppm in 2019[3] to 1,000ppm in 2021 due to the encouraging results received from metallurgical test work completed by Jindalee over the past 18 months[2,4,7 ] which demonstrated the ore can be beneficiated before leaching. This significantly increases confidence in the ability to reduce operating costs which impacts directly and positively upon the reasonable prospects for eventual economic extraction (as per JORC Code 2012). The results of the MRE (Table 1) and ETR (Table 2) at a full range of cut-off grades demonstrate the scalability of the project.

Table 2 – Summary of McDermitt Exploration Target Range at varying cut-off grades, with preferred reporting cut-off of 1,000ppm highlighted. Note: totals may vary due to rounding.

Recent infill drilling[6,8,9] has increased confidence in geological and grade continuity through the centre of the deposit, allowing conversion of part of the existing Inferred Mineral Resource to Indicated (Figure 1). Furthermore, there is significant scope for resource extensions of the deposit to the west and south in Jindalee’s new claims[11] , as well as infill drilling of the Inferred material.

The results from the 2021 Mineral Resource update and the material uplift in contained lithium reinforces the significance of the McDermitt project as a potential source of future supply to the rapidly growing US battery manufacturing industry. Jindalee intends to continue de-risking the project through further metallurgical studies aimed at the downstream processing flowsheet ahead of a potential Scoping Study in the June quarter of 2021.

The 2021 drill program will be finalised based on the updated MRE with the aim to infill and further upgrade the Resource and to define the full extent of the lithium mineralisation at McDermitt. Applications for drill permitting are expected to be submitted in April 2021.

A full summary of all drill hole data included in the MRE is in Annexure A.

Mineral Resource and Exploration Target Methodology

Jindalee commissioned H&S Consultants Pty Ltd (H&SC) to update the Mineral Resource Estimate (MRE) following the completion of the 2020 drill program. The MRE is based on all available information as of 31 March 2021.

Mineralisation and Geology

Lithium mineralisation occurs within a sequence of flat-lying, paleo-lake sediments that overlie a volcanic (basalt) basement within the Tertiary aged McDermitt Caldera. The maximum drill hole intersection of mineralised sediments is now 179.8 m and averages 131.7 m in holes where the basalt basement was intersected. The mineralisation appears to have a strong stratigraphic control with no obvious faulting or folding identified to date. A typical cross section demonstrating relationship between grade and geology is shown in Figure 2.

Drilling and Sampling Techniques

A total of 29 drillholes (16 Reverse Circulation (RC) and 13 Diamond) were used in the estimation. Diamond drill core was collected as HQ triple tube and quarter cut for assaying whilst RC drill samples were either riffle split (dry) or rotary split (wet) on site. All samples were submitted to ALS for assaying via 4 acid digest of 0.25g sample split with a 48 element ICP-MS finish.

Qualitative lithological descriptions (colour, weathering, grain size, lithology, mineralogy, veining textures and other significant features) were recorded by the field geologist for both diamond and RC programs.

Density

No new density measurements were taken in 2020 as all holes were drilled as RC. Specific Gravity (SG) was assigned to the model through the formula:

"�� = 1.4134 + ����ℎ ∗0.0012"

At a 1000ppm cut-off, the average assigned specific gravity is 1.53.

Estimation

Wireframe surfaces were generated for the top and bottom of the paleo-lake sediments and used to constrain the estimate into three domains (sediments, colluvium, and basement).

Sample data were composited to 2m for analysis and grade estimate as this is the dominant sample length. There were no extreme values present in statistical data analysis so no treatment for outliers was required.

==> picture [559 x 74] intentionally omitted <==

Lithium was estimated using Ordinary Kriging (OK) for all domains. Variogram modelling indicating mineralisation may be trending NW-SE direction which corresponds to drainage in the claim area. Block size for estimation was 200mE by 200mN by 5mRL with sub-celling permitted to 40mE by 40mN by 1mRL.

Validation

The model was validated in several ways including visual comparison of block and drill hole grades, statistical analysis, examination of grade tonnage data and comparison with previous model. No material issues were identified.

A comparison of the grade versus tonnage curve for the 2019 MRE and the 2021 MRE is demonstrated in Figure 3. At the previous reporting COG of 1,750ppm Li, there is a small decrease in total tonnes, and a slight increase in grade for an overall drop in contained metal of approximately 15%. This may be a result of the different drilling methods employed from the 2019 MRE (diamond) to the 2021 MRE (RC) with twinned holes planned for 2021 to address any bias concerns.

Classification

Mineral Resources were classified based on consideration of data quality and spacing as well as geological and grade continuity. Indicated Mineral Resources are confined to an area of closer spaced drilling with holes nominally drilled 400m apart, while Inferred Mineral Resources were restricted to blocks within 1,000m of the nearest hole. All Mineral Resources are within 100m of surface, with at least 3 holes and 12 samples required to inform these blocks.

The lower end of the Exploration Target range is defined by a horizontal search radius of 3,000 m while the upper end is defined by a 6,000 m horizontal search radius. No depth restriction was imposed and at least 2 holes and 8 samples were required to inform these blocks; maximum depth of the Exploration Target is ~250 m below surface. Grade ranges are the estimated grades +/200ppm Li. The Exploration Target now includes a small proportion of colluvium material overlying the mineralised lake sediments with no material with significant grade in the basement basalts.

Metallurgy

Since the completion of the maiden Mineral Resource in 2019, Jindalee has completed several metallurgical studies focussing on beneficiation and sulphuric acid leaching at Hazen Research labs.

Results from leach testwork undertaken on bulk (non-beneficiated) samples in 2019 indicated lithium recoveries of >95% with short residence times using sulphuric acid (H2SO4) leach at moderate temperatures and atmospheric pressure, with potential to reduce acid consumption via recycling of the leachate[2] .

In August 2020 Jindalee announced that beneficiation of McDermitt ore via attrition scrubbing at 20% solids had increased the lithium content in the <0.01mm fraction by more than 50% (from 0.22% to 0.34%) and had reduced carbonate and analcime (both acid consuming minerals)[4] .

The latest attrition scrubbing testwork, designed to produce a beneficiated sample for leaching experiments, increased the lithium content in the <0.01mm fraction by 60.9% (from 0.23% to 0.37%)[7] . Furthermore, initial leaching experiments on beneficiated samples demonstrated lithium extraction rates of 94-97% with 26% less acid consumed per lithium unit than for previous similar experiments on non-beneficiated ore. The testwork also indicated that the residue remaining after leaching is relatively benign, comprising quartz, feldspar and gypsum.

Reporting Cut-off Grade

Mineral Resources were previously reported at a 1,750 ppm Li cut-off grade. However Mineral Resources are now reported at a 1,000 ppm Li cut-off grade because recent metallurgical testwork has shown that beneficiation of McDermitt ore by attrition scrubbing can increase the lithium content by up to 60%[7] . This is anticipated to positively impact on operating costs through mass reduction of the ore before processing and decreased acid consumption during leaching. These results indicate that significant lower grade material than initially anticipated can now be processed.

All other details pertaining to the reporting of exploration results and Mineral Resources are detailed in Annexure B.
