Perpetual Resources Limited (ASX: PEC, "PEC", "Perpetual" or "the Company") is pleased to announce exceptional white sand test results as well as the delineation of multiple geological/mineralogical domains within the white sand sequence at Beharra. Perpetual now believes there is strong potential that Beharra hosts an even higher quality silica sand product from a sub-domain within the white sand horizon, with a quality that shows strong potential to surpass the exceptional results of the most recent testing.

Representative white sand bulk metallurgical test results from the recent testing program conducted by IHC Robbins in Brisbane have now been received. These results showed a material reduction in the key impurity Fe2O3 (iron oxide) of 37% and have also highlighted that distinct geological / mineralogical differences exist within the high-quality white sand sequence at Beharra. These differences demonstrate a clear chemical demarcation within the white sand domain, indicating the presence of a higher quality upper unit combined with a lower sub-unit, previously understood to be one broadly homogenous white sand horizon. The attributes of the upper unit suggest that an even higher quality final product is possible from this sub-unit, which appears to contain the same (or potentially higher) SiO2 content, but with a significant reduction in key impurities. As the upper unit is a sub-set of the metallurgical results announced today, Perpetual will be exploring the likely thesis that the upper sub-unit will be higher quality than the overall bulk metallurgical test results announced today.

Mr. Julian Babarczy, Executive Chairman of Perpetual, commented on the results, "Today's announcement of multiple geological domains within our already high-quality white sand sequence at Beharra is yet another improvement to our previous understanding of the quality of the Beharra deposit. The results announced today, which are exceptional in their own right and clearly show why Beharra is the leading Midwest silica sand project, point to the proposition for an even higher quality end product, with additional test work now being planned. With a significant amount of drill sample remaining from the recent 86-hole air core program completed in June 2021 at Beharra, we have commenced the collection of multiple bulk samples that will reflect each of the white sand sub-domains with subsequent testing aiming to confirm the presence of the higher quality upper sub-domain that will form the basis of Perpetual's marketing efforts into the high growth Asian ultra-clear glass markets".

Background

After the success of the initial 300kg white sand sampling results at Beharra, announced in April 2021 (please refer to ASX announcement dated 22nd April 2021, titled "Exceptional metallurgical test results at Beharra deliver game changing impurity levels"), Perpetual undertook an additional 86 hole air core drilling program, the results of which were announced in August 2021 (please refer to ASX Announcement dated 30th August 2021 titled "Phase 3 air core infill drilling results confirms high grade white silica sand at Beharra"). This drill program targeted an area of the Beharra deposit

situated at the southernmost extent of the Beharra Mining License (please see Figure 1 below) and was aimed at extracting white sand only drill samples for use in a bulk representative metallurgical testing program that would confirm the metallurgical characteristics of a white sand only processing scenario over an initial 10 years of mine life at Beharra.

Figure 1 – Location of Beharra drill holes from all drilling campaigns undertaken by Perpetual, with the red dots representing the most recent 86-hole program

IHC Robbins Testing

The drill samples were sent to IHC Robbins in Brisbane where they were sorted and selected on the basis of the mineral resource modelling and reflecting the proposed mining process (i.e., topsoil removal, exclusion of samples classified as yellow, grey or high silt/clay content unless these occur as thin bands within the planned ore to be mined).

Once the sample was sorted and composites made from each drill hole, they were then combined to produce the master composite sample. This was then subjected to a pre-screen to remove any oversize (+1.0mm) components, followed by a hydrocyclones to reject fines (-75µm), Wet High

Intensity Magnetic Separation (WHIMS) to remove magnetic fractions, two stages of spiral separation for further classification, an up-current classification stage to reject -150µm fines, followed by a final screening stage. For detail on the flow sheet for this round of testing, please see Figure 2 below.

The only notable difference between the flow sheet shown in Figure 2 on the previous page and the flow sheet that was utilised in the Beharra PFS Study, is the sequencing of the WHIMS stage prior to the spirals in the most recent testing program. This change in order was made to provide a more effective removal of the magnetic iron oxides with a lower loss of potential silica sand pre the spirals. This significantly reduced the duty for the spiral stages and provided an increase in final product yield (i.e., the yield to premium product increased from 74.4% to 77.8%).

Exceptional Metallurgical Results

The results of the IHC Robbins testing showed a substantial increase in overall product quality when compared to the Beharra PFS results. The test results showed no sacrifice to the high SiO2 content concurrent with a significant reduction in the key impurity of Fe2O3, which was 37% lower, when compared to the Beharra PFS results (please see graphical representation in Figure 3 below). To the best of Perpetual's knowledge, these results suggest that the white sand horizon at Beharra is the highest quality known silica sand horizon in the Midwest region, which can produce a very low impurity final product that will ideally service the fast growing clear and ultra-clear glass markets of the Asia Pacific region.

Identification of Beharra White Sand Domains

With the high quality of the white horizon at Beharra now confirmed to contain SiO2 content of 99.6% and Fe2O3 content of circa 173ppm in final product, Perpetual's project team has subsequently undertaken additional analysis to identify sub-domains within Beharra white sand sequence. This analysis was undertaken by linking drill hole geochemistry with the mineralogy of the various drill holes within the Beharra white sand sequence and has clearly identified the potential for a premium horizon of white sand within the overall sequence.

The master composite sample used for the metallurgical test work was designed based on a visual appraisal of the drill samples, rather than on chemical composition, which led to the inclusion of some drill sample material that was outside what is now considered the white sand horizon at Beharra. When the individual drill hole geochemistry (assay) and lithology samples were compared to the drill hole composites, it was possible to characterise the various domains within the Beharra deposit (based on the drill samples that were selected to comprise the bulk sample) as possible standalone sub-units. It should be noted that the information contained in Figure 4 below is indicative only, with Perpetual to now undertake follow up testing and analysis of the various sub domains within the white sand sequence by way of preparation of individual bulk samples for each subdomain, which will be processed by IHC Robbins in Brisbane and analysed to confirm the chemical characteristics of the individual potential final product from each sub-domain.

Beharra Sub-Domains Number of samples Proportion SiO2 Fe2O3 AL2O3 LOI
Yellow 12 2% 99.15 0.08 0.22 0.3
White Upper 305 42% 99.035 0.13 0.28 0.19
White Lower 244 34% 98.302 0.21 0.61 0.24
Grey Pod 1 0% 98.8 0.18 0.28 0.29
Grey 159 22% 93.103 0.33 4.05 1.35

Note: Table is indicative only, with all calculations based on an arithmetic average of included drill holes only

Figure 4 – Indicative analysis of the samples that were selected to comprise the bulk sample in the most recent metallurgical test work at Beharra

This analysis yielded two important observations that have potential to further increase the end product quality offered by the Beharra deposit:

  1. It is apparent that the inclusion of the Grey sub-unit in the most recent metallurgical test work has negatively impacted the end results, by reducing the overall SiO2 grade commensurate with higher Fe2O3 and Al2O3 values in the final product. It is now believed that excluding the Grey sub-domain is likely to materially increase the overall quality of the white sand final product, assuming the entire white sand sequence was processed as one unit.

  1. There appears to be markedly different chemical compositions and impurity profiles of the various sub-domains within the overall white sand sequence, which leads to the opportunity to conduct further analysis of the potential quality of sub-domains by way of individual subunit bulk metallurgical test work.

As described in the Mineral Resource estimation announced in March 2021 (please refer to ASX Announcement dated 9th March 2021 titled "Upgraded Mineral Resource estimate for Beharra results in a 25% increase in tonnage to 139 Mt at 98.6% SiO2") the white sand sequence at Beharra is effectively a sequence of stacked sub-domains. The expectation (derived from analysis contained in Figure 4 on the previous page, see also Figure 5 in the announcement of 9th March 2021) is that the upper domain should exhibit superior final product qualities if mined and processed as a distinct horizon. Figure 5 below shows a graphical interpretation of the current understanding of the subdomains within the white sand sequence at Beharra.

Figure 5 – Cross Section C022-C025 showing interpreted domains within the Beharra white sand sequence, and the composites used for the metallurgical testing as reported herein

With the information derived from this test program, the upper unit within the Beharra white sand sequence has potential to produce a higher-premium low iron silica sand product, ideal for the fast growing ultra-clear glass markets in Asia, including the PV-solar cell coverings market, which is undergoing significant growth in response to the rapid increase in solar energy generation globally.

Additional Test Work to Confirm Quality of sub-Domains

To confirm the presence of a higher-premium horizon at Beharra, Perpetual will now undertake additional bulk sampling, sourced from drill samples obtained in the most recent 86-hole air core drilling program at Beharra.

Drill samples are currently being transported from their storage location in Dongara, Western Australia, to the IHC Robbins laboratory in Brisbane. Once in Brisbane, representative bulk samples of the various sub-domains will be drawn from the drill samples, which will then be tested in production scale equipment to arrive at a conclusive metallurgical understanding of each subdomain. This will also generate significant volumes of final product samples for shipment to potential offtake customers.

It is Perpetual's proposition that this has a strong potential to identify the upper sub-unit as a higherpremium product, with materially lower Fe2O3 and Al2O3 than reported in the exceptional white sand test results today.

It is anticipated that results of this follow-on test work will be received early in 2QCY22, although this timeline is subject to the current high rates of testing work that is being experienced in minerals testing laboratories throughout Australia at present.

Offtake Discussions to Advance

Given these exceptional results now confirm the quality of the white sand only testing program, Perpetual will progress offtake discussions and negotiations in earnest. With the identification of possibly higher quality sub-units within the white sand sequence at Beharra, it is expected that offtake discussions may be optimized by a focus on the potential higher quality product that might be derived from the upper sub-unit, results of which will be known in 2QCY22.

Perpetual will look to update the market in coming months as these discussions progress.

Beharra Study Update

Perpetual considers that the verification of distinct sub-domains within the Beharra white sand sequence suggests strong potential for a further significant increase in final product specifications

(with potential for a further reduction in impurities). As such, the planned timeline of the Pre-Feasibility Study Update (PFSU) is being re-assessed to likely include results of the additional bulk metallurgical test work to be caried out on each of the identified sub-domains.

Shareholders will be updated in coming weeks as to the revised timetable for the delivery of the PFSU, although any decision to include this new metallurgical information is not anticipated to materially affect the overall project timeline.

About Perpetual Resources Limited

Perpetual Resources Limited (Perpetual) is a focused explorer of silica sands, aiming to produce high purity silica for export to the high growth Asian markets.

Perpetual's flagship asset, the Beharra Project (Beharra) is located 300km north of Perth and is 96km south of the port town of Geraldton in Western Australia. Access to the Project from Geraldton (to the north) and Perth (to the South) is via the sealed Brand Highway, thence approximately 8.5km east on the Mt Adams unsealed road providing access to the center of the tenure.

The port of Geraldton is an established bulk material handling facility and is currently utilised for the export of bulk materials, minerals, grain and concentrates. Commodities currently exported via Geraldton Port include grains, copper concentrates, zinc concentrates, nickel concentrates, mineral sands, talc, and iron ore.

Beharra comprises a granted mining lease, M70/1406, covering an effective area of 10.4km2 , and a granted exploration license, E70/5221, covering an effective land area of 56.8km2 . Extensive heavy mineral sands mining occurs to the south of Beharra, lime sands mining to the west and natural gas production to the south of the project area.

Auger and air core drilling has confirmed the presence of extensive, high purity silica sands, with a maiden Mineral Resource Estimate completed in July 2020. A detailed Pre-Feasibility Study demonstrating compelling project economics was for Beharra was released to the ASX in March 2021, along with a Maiden Ore Reserve.

Silica Sands Market

Silica sands have an extensive range of uses, with lower purity (<99.5% SiO2) and lower priced applications including construction sand, proppant sand used in well fracturing, and foundry sand. With increasing purity (>99.5% SiO2) and price, uses include glass making including ultra-clear glass, with a main determinant of the sand's suitability for specific applications and pricing being the level of the key impurity iron oxide (Fe2O3). Significant expansion of solar PV cell manufacturing capacity globally is driving demand for silica sand with Fe2O3 content of <200ppm and lower, which is a key focus market for Beharra.
