Arcadia Minerals Ltd (ASX:AM7) ( Arcadia or the Company ) is pleased to announce that BME, has taken cession ( Deed of Cession ), subject to approval by shareholders of the Company (as is required by Asx), of an acquisition agreement ( Acquisition Agreement ) to acquire up to 100% of the Exclusive Prospecting Licenses 5358, 5354 and 5353 ( Licenses ) in Namibia.
The Licenses contain an inferred JORC Mineral Resource of 15.1 million tons @ 828ppm Li and 1,79% K (at a cut-off grade of 680ppm Li) and holds the potential to host a lithium-inbrines aquifer.
Acquisition Agreement
LexRox Management Services (Pty) Ltd ( LexRox ), a South African company owned and operated by the executive directors of Arcadia, entered into the Acquisition Agreement to acquire the Licenses on 1 February 2019. No consideration in relation to the cession and assignment is to be paid by BME or Arcadia to LexRox except to reimburse expenses amounting to $18,000 associated with the preservation of the EPL’s and to keep the Acquisition Agreement in good standing.
In pursuance of the Acquisition Agreement, the Licenses, all of which are located near the towns of Kalkrand and Hoachanas in the Hardap Region of central Namibia, were transferred with approval from the Ministry of Mines and Energy of Namibia from the License-holder to Bitterwasser Lithium Exploration (Pty) Ltd ( BLE ), a company that was formed for the purpose of developing the exploration potential of the Licenses.
Further details of the EPL’s can be found in Annexure 4 below. In terms of the Acquisition Agreement, BLE is currently 100% owned by the original owner of the Licenses, Mr Leon van Neel, until completion of the acquisitions pursuant to the Acquisition Agreement.
In terms of the Deed of Cession entered into between LexRox and BME, all rights, title and interest incumbent upon LexRox in terms of the Acquisition Agreement were ceded, assigned, transferred, and made over by LexRox to BME. Following completion of the Deed of Cession, LexRox will no longer hold proprietary rights to the EPL’s, or in the share capital of BLE or hold
Page 2
==> picture [105 x 65] intentionally omitted <==
any personal rights in relation to the Acquisition Agreement. To complete the Deed of Cession, BME has acceded in writing to the terms of the Acquisition Agreement.
In terms of the Acquisition Agreement:
-
LexRox has the right to cede and assign its rights and obligations in terms of the Acquisition Agreement to any third party subject to such third party agreeing to accede to the terms of the Acquisition Agreement;
-
BME (as cessionary) is entitled to appoint two directors out of three until completion of the terms of the Acquisition Agreement;
-
BME (as cessionary) has the right to conduct further exploration up to 16 May 2022, before which date BME may exercise an option (first option) to acquire 25% in the share capital of BLE from Mr. Leon van Neel for a consideration of N$1M (~A$87,000), to be funded by Arcadia through budgetary savings;
-
BME (as cessionary) has the right and a second option to conduct further exploration operations for an additional 2-year period after it completed the first option to acquire the balance of Mr. Leon van Neel’s equity interests in BLE of 75% for a consideration of N$2M (~A$176,000), the second payment term is due outside the current budget scope, and;
-
BME (as cessionary) must pay an additional consideration equal to N$7M (~A$615,000) upon the completion of a definitive feasibility study (DFS) over a resource containing not less than 500,000 tons of LCE arising from potential lithiumin-brines resident under the Licenses at a minimum viable grade that results in a positive DFS.
Shareholder approval for the proposed transaction will be sought pursuant to ASX Listing Rule 11.1.2. A notice of meeting will shortly be dispatched to shareholders wherein full disclosure will be made of the proposed transaction in pursuance of the Deed of Cession and the Acquisition Agreement, including an independent technical report and a solicitor’s report on the tenements, a detailed work program and the proposed use of funds in relation to the Licenses being acquired.
Exploration will be funded by Arcadia in accordance with the terms of the BME shareholders’ agreement as disclosed in the Company’s Replacement prospectus of 15 April 2021 to the effect that the Company continues to be responsible for sole funding all expenditure incurred until completion of the minimum work program, at which time the Company will then assess progress to make an election to move forward or dilute.
The potential acquisition is expected to complement Arcadia’s 3,438km[2] tenure at the adjacent Bitterwasser Lithium-in-Brines Project. The proximity and relationship between the BME and BLE exclusive prospecting licenses are indicated in Annexure 5. If completed, the Acquisition will lead to BME holding an extensive land package of approximately 4,031Km[2] in

extent, which covers most of the prospective ground over the Kalkrand Half-Graben. The Kalkrand Half-Graben displays first order requirements to possibly qualify as the world’s latest district scale Lithium province similar to Clayton Valley in Nevada, USA.
Mineral Resources
The JORC Mineral Resource, defined as a maiden resource for the Bitterwasser Lithium-inclay Project, comprises 15.1 million tons @ 828ppm Li and 1,79% K (at a cut-off grade of 680ppm Li) , which is wholly classified in the Inferred category. A Mineral Resource statement for the Bitterwasser Lithium-in-clay Project is presented in Annexure 1 and further details as are required in terms of a JORC Mineral Resource are set out in the tables provided in Annexure 3. A total of 16 hand-auger holes were drilled into the clay sediments of which 14, which intersected lithologies, were sampled. A table of all the drill-holes is included in Annexure 2. The Mineral Resource represents only 6% of the exposed clay pans within the three new EPL’s covering ~593km[2] and provides the Company with extensive geological knowledge, which will greatly assist the Company in its understanding of the Lithium potential on its existing ~3,438km[2] of clay pans and brines potential.
A cut-off grade of 680 ppm lithium was applied in selection of the resource blocks that were to be included in the calculation of the Mineral Resource. This is considered an economic cutoff based on cash-flow analysis conducted by the Competent Person. However, some resource blocks that are below the cut-off grade are included within the 5-Year Forecast plan in instances where the blocks are required to be mined to extract the economic pay portion of the total resource, either for geological or geotechnical considerations.
Sufficient information in the form of crucial modifying factors exists to permit the estimation of a Mineral Resource for this deposit. Bench scale metallurgical test work of the potential recoveries of Li from the Clay Units has been successfully completed. Leaching test work of the Clay Units demonstrated that:
-
Li is recoverable using feasible volumes of sulphuric acid,
-
a viable sequential precipitation method of deleterious magnesium (and other cations) sulphates is achievable, and;
-
the extraction of lithium to a marketable lithium carbonate (or hydroxide) product is possible.
However, detailed investigations concerning mining-, processing-, metallurgical-, infrastructure-, economic-, marketing-, legal-, environmental-, government- and social factors (“modifying factors’; JORC, 2012) have not been undertaken to date at Bitterwasser. The volume estimated for the drilled resource area is 9 465 100 m[3] . Using the average calculated density of 1.6 g/cm[3] for the Upper and Lower clay, the estimated resource is 15 144 160 tons at grades of 828 ppm Li and 1.79% K.

Table 1: The estimation results based on a cut-off grade of 680 ppm Li.
The Mineral Resource covers approximately 6% of the exposed clays in the 7 known pans contained in the Bitterwasser Pan District. Mineralisation at the Bitterwasser main pan may extend in a northerly and southerly direction and to depth.
Seventy-four auger drill hole samples of both clay lithological units were collected and prepared for ICP-OES and ICP-MS rare earth element analysis (Li only) and density determinations. Both the analyses were done by SGS South Africa laboratories. A clear geochemical distinction between the Upper- and Lower clay units was identified, with the Lower Clay Unit being relatively more enriched in Li, and K were found to exist. Drillholes across the central and marginal portions of the pan displayed average grade values for the Upper Clay Unit as 551 ppm Li and 1.56 % K, with an average thickness of 2.47 m, while the average grades for the Lower Clay Unit are 767 ppm Li and 1.75 % K at an average thickness of 5.00 m. Both the Upper clay and Lower Clay Units demonstrate a correlation between increasing K content and increasing Li content, with both elements appearing to be correlated to each other. Refer to Annexure 8 for more borehole information illustrating this correlation.
Comparable Clay Projects
Lithium production from clays on a commercial scale is still in its infancy; however, several companies are currently working towards implementation of recently developed lithium recovery techniques from clays.[1]
Clay deposits in similar geological settings are presently being developed in Clayton Valley in Nevada USA, by Cypress Development and Noram Ventures in close proximity (within 1.5km[2] ) to the Lithium-in-Brine operations of Albermarle Corp. and Pure Energy Minerals.[2]

Cypress Development initially (before additional exploration) reported average lithium grades of 867 ppm Li, while Noram Ventures reported lithium grades of 858 ppm Li, which is very similar to the estimated average grade of the Mineral Resources reported to date within the Bitterwasser Main Pan.[3]
Electromagnetic Survey and Brines Potential
An electromagnetic (EM) survey was completed by groundwater consultancy Geoss during October 2019. This survey involved the dragging of an EM antenna (rings) at a 40 m or 20 m grid spacing behind a vehicle (See Annexure 9). An electrical conductivity map was generated using the data acquired from the EM survey (See Annexure 10). The north section indicates a highly saline body (red to yellow contours) in the centre of the section. The conductivity measures from -500 to -250 mS/m which in this case is interpreted as a concentrated saline body and was measured with the 40 m coil separation. The southern section which was done with the 20 m coil separation, and this clearly does not show such a prominent body. However, negative conductivity (interpreted as highly saline material) is still clearly indicated in the south section. The conductivity in this section ranges from -200 to -50 mS/m.
The difference between the 20 m and 40 m coil separation is clear on the conductivity map (Figure 7) and confirms that the body delineated by the 40 m coil separation extends deeper than 30 m (known depth extent of 20 m coil separation) and shallower than 60 m (know depth extent of 40 m coil separation).
It was found that the geological and environmental requirements for the formation of significant lithium brine deposits are present[4] . Sufficient evidence exists to suggest the

presence of several lithium bearing brine aquifers in the Kalkrand Half-Graben. This evidence includes water-quality data (total dissolved solids and electrical conductivity) from Government borehole data, that indicate the presence of brines in the Bitterwasser basin (the brines were however never tested for Li) as well as the presence of conducive structures (observed from magnetic geophysical data) that form an enclosed basin.
Other economically significant lithium saltpan complexes around the world are associated with anomalous Li, K and B values. The lithium mineralisation associated with the drilled area of the Bitterwasser Main Pan, Li > 800 ppm, B values of > 400 ppm and K values > 1.7 %, emphasises the geochemical similarities with other globally significant lithium brine complexes. Radiometric data over the basin also show anomalous K values associated with the Bitterwasser Salt Complex.
Next steps
As potential exists to increase the existing resource over exposed clay pans, Auger Drilling is planned to commence in November 2021 over the Main Bitterwasser Pan and to test extensions of mineralisation over the rest of the Bitterwasser Clay Pan District. If successful, the drill results will be utilised to possibly increase the resource.
Sub-surface clay potential is also to be investigated through Auger Drilling over the existing 3,438Km2 of the Bitterwasser Lithium Project.
A “Proof-of-Concept” study for Lithium Brine potential at Bitterwasser is underway to guide exploration over a geological feature known as the “Kalkrand Half-Graben”.
BME has linked up with a German lithium processing company Anzaplan (Dorfner Group) that will conduct detailed mineralogical and bench scale metallurgical test work on 200kg each of the Upper and Lower Clay Units with the aim of producing a preliminary process flow chart. The detailed mineralogical and bench scale metallurgical test work would later be complimented with a bulk sampling campaign.
Additional Information: Bitterwasser Pan District
Exploration work conducted by LexRox since 2019 was limited to the Bitterwasser main pan. The work included a ground electrical conductivity survey, the hand-auger-drilling of 16 drillholes on a 500m grid over the central parts of the main pan and the analysis of 74 auger drill core samples. The ground electrical conductivity survey conducted identified an anomalous electrical-conductive body that may indicate the presence of a lithium-in-brine aquifer at depth.
Page 7
==> picture [105 x 65] intentionally omitted <==
The shallow hand auger drilling programme, which forms the basis of the Mineral Resource, covered approximately 26 % of the entire surface area of the Bitterwasser main saltpan. Results from the drilling program indicated the presence of significant lithium-in--clay mineralisation overlying the anomalous electrical-conductive body identified during the ground electrical conductivity survey. The lithium-clay mineralisation intersected within the relatively small area prospected was spatially continuous, trended moderately sub-parallel to the long axis of the saltpan and consistently yielded prospective Li grades. The clays increased in thickness and lithium content towards the central portions of the pan where Li grades approaching 1,200 ppm were encountered, which is in-line with similar projects situated near producing lithium mines in other parts of the world.
The exploration programme was aimed at characterizing the general stratigraphic sequence and to investigate the pan’s lithium potential in terms of economic viability. Auger sampling confirmed the presence of a lithium-in-clay resource comparable in grade and extent to that owned by major exploration companies in Nevada, USA. In addition, it was found that the geological and environmental requirements for the formation of significant lithium-in-clay and lithium-in-brine deposits are present. However, the lithium grade in the indicated brines are yet to be confirmed through appropriate exploration techniques. Sufficient evidence exists to suggest the presence of a lithium-in-brine aquifer in the Bitterwasser Saltpan district.
Supporting evidence comes from geological and environmental indicators identified through Bitterwasser Lithium Exploration (Pty) Ltd’s reconnaissance exploration efforts to date. Such evidence includes water-quality data (total dissolved solids and electrical conductivity) from domestic water supply boreholes in the area, lithium-in-clay grades from hand auger drilling and associated electrical-conductive anomalies, the presence of conducive regional tectonic structures, favourable source rocks and climatic conditions in proximity to an enclosed basin. Such geological and environmental indicators are comparable in nature to known lithium-inbrine districts in other parts of the world.
Other economically significant saltpan districts around the world are associated with anomalous K and B values. The lithium mineralisation associated with the lithologies documented at Bitterwasser’s main saltpan yielded B values of > 400 ppm and K values consistently > 1.8 wt. %. This emphasises the geochemical similarities with other globally significant saltpan districts.
The Bitterwasser Saltpan District is associated with the depositional development of the western portions of the greater Kalahari basin. It lies remarkably close to the inferred source of mineralisation, being the alkaline Brukkaros volcanic field. Elevated groundwater temperatures, as high as 39 °C, have been reported from domestic water-supply boreholes in close vicinity to the saltpans suggesting a deep-seated geothermal heat source and mineralisation mechanism. The thickness of the sedimentary packages which make up the
Page 8
==> picture [105 x 65] intentionally omitted <==
Bitterwasser saltpans range between 30 m to 100 m thick and are of sufficient size and porosity to accommodate substantial brine aquifers. Annexure 6 shows the location of the Bitterwasser Saltpan District.
The discovery of the Bitterwasser Saltpan District was preceded by the sampling of saltpan clay sediments from several saltpan districts throughout southern Namibia and northwestern South Africa over a total area of some 450 km x 200 km. Out of the 130 samples taken over all the pans in the area, the Bitterwasser Saltpan District showed anomalous lithium values. At this initial stage, 26 surface samples were taken from the Bitterwasser saltpans of which 16 samples returned values between 300 to 550 ppm Li and Boron values as high as 400 ppm.
The Bitterwasser Main Saltpan (1,550 ha in surface area) forms part of the Cenozoic aged Kalahari Group and comprises a lithium, potassium and boron enriched sulphate, chlorite and carbonate saltpan district consisting of 7 pans, totalling 6,939 ha in surface area. The pan sediments can be divided into two stratigraphic units. A lower, relatively lithium poor, partially consolidated and/or indurated, poorly sorted and graded unit; dominated by sand, grit and pebbly-grit, with minor to moderate clay constituents and an Upper, lithium enriched, unconsolidated, well sorted and reasonably homogenous unit; dominated by clay and siltyclay. A well-developed redox (reduction-oxidation) boundary occurs throughout the pan which crosscuts the Upper Unit. The redox boundary is recognized through a change in colour of the clays with increasing depth. Near surface oxidized clay exhibit white, brown, greybrown or orange (sometimes mottled) colours (Upper Clay), while the colour of the deeper reduced clays gradually changes from light olive green to dark olive green with increasing depth (Lower Clay). Refer to Annexure 7 for stratigraphy of the Bitterwasser Main Saltpan.

Notes:
The Mineral Resource Estimate was completed using the following parameters:
| Strike and drill spacing | Drill lines are orientated east-west (perpendicular to the strike of the pan) and spaced 500 m apart. |
|---|---|
| Style of Mineralisation | Mineralisation in the Bitterwasser Pan comprises a lithium, potassium and boron enriched sulphate-, chlorite- and carbonate- salts in pan sediments. The lithium mineralisation took place in the pan surface sediments where interaction between basin sediments and pore-water brines governed by the chemical equilibrium reactions of cation exchange and mineral solubility resulted in the precipitation of lithium in the clays in thepan. |
| Description of Drilling | Auger drillholes were spaced on a 500 m x 500 m grid, with 3 drill lines and 5 to 6 holes per drill line, drilled to a maximum depth of ~12m. A total of 16 holes were drilled totalling 93.10 m. |
| Samples analyses | SGS laboratory in Randfontein, South Africa. Sodium peroxide fusion ICP-OES with an ICP-MS finish analysis for major elements. Initial sequential leach(metallurgical)test work. |
| Quality control protocols | Standard Operation Procedures were followed including the use of duplicate, blank and reference samples. The reference samples consisted of African Minerals Standards (Pty) Ltd (AMIS) certified reference materials and were inserted on average every 6 – 7 m within the samplingstream. |

| Azimuth/Dip /Vertical | Drillholes were drilled vertical |
| Cut-off grade to construct geological domains | A cut-off grade of 680 ppm Li has been applied duringestimations. |
| Intersections used in the interpretation are listed in Annexure 2. | |
| Resource modelling | Wireframes constraining mineralisation were based on a minimum down-hole depth of 3 m grading >680 ppm Li. Mineralisation envelopes were projected quarter drillhole spacing at edges of the deposit when mineralisation was open. |
| Geostatistical methods used to estimate block grades |
Block grades were calculated by Ordinary Kriging and Inverse Distance Squared methodologyforquotingthe resource. |
| Constraining of model | The model was constrained by using the intercept table in Surpac and verified against cross sections of the model. |
| Block model software used for the estimate and block sizes and sub-blocking |
Block model Surpac was used for the estimate with a block size of 60 m3, 20 m on strike and 3m in the dip direction, with sub-blocking to 15m3. |
| Bulk density values and source of values. | A density value of 1.6 g/cm3was used during estimations and was sourced from Heckroodt, 1991. |
| The deposit has been classified as an Inferred Mineral Resource based on data quality and sample spacing. |
|
| Recommendations | Bitterwasser Lithium Exploration (Pty) Ltd is to execute further exploration work on the clays of the pan complex and to potentially delineate the saline and/or brine aquifer system in the Bitterwasser saltpan complex. Priority should be given to the underlying sandy clay unit and areas to the north and south of the area explored. |
These notes should be read in conjunction with the information detailed in Annexure 3.

|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information. |
• Sampling was undertaken using industry standard practices and consist of hand-auger drilling by Bitterwasser Lithium Exploration (Pty) Ltd. during 2019. • All drill holes are vertical • A total of 89 samples were taken from the core of the drilling campaign, of these 74 where for chemical/metallurgical analysis and 15 for QAQC purposes. • Samples ranged from 1012 g to 42 g. • An additional 15 density samples were collected. • To minimize sample contamination, the collected sediment samples were placed on a canvas cloth, while the clay-bit was cleaned with a wet cloth and water after every sample. • All drill hole and sample locations are mapped in WGS84 UTM zone 33S • During 2010 sampling was undertaken using industry standard practices and consisted of surface sampling by Botha & Hattingh,(2017). • 24 soil samples were taken from pits of 1.5 m depth. Two (2), 500 ml groundwater samples were taken from taps attached to the windpumps. |

| 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. • 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. |
• A cut-off grade of 680 ppm Li was used. The estimated volumes and grades are based on this cut-off grade. |
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • 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’). _ |
• The drill holes were all drilled vertical, with the clay units being horizontal. • The mineralized clay thickness intercepted range from 1 m to 9 m. |

• Assumptions made regarding possible mining methods, minimum mining dimensions and internal (or, if applicable, external) mining dilution. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential mining methods, but the assumptions made regarding mining methods and parameters when estimating Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the mining assumptions made. |

• The basis for assumptions or predictions regarding metallurgical amenability. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider potential metallurgical methods, but the assumptions regarding metallurgical treatment processes and parameters made when reporting Mineral Resources may not always be rigorous. Where this is the case, this should be reported with an explanation of the basis of the metallurgical assumptions made. |
• No assumptions have been made. |
| Environmental factors or assumptions |
• Assumptions made regarding possible waste and process residue disposal options. It is always necessary as part of the process of determining reasonable prospects for eventual economic extraction to consider the potential environmental impacts of the mining and processing operation.

If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. |
• Bitterwasser Lithium Exploration (Pty) Ltd collected 15 samples to determine the specific gravity (SG) of the clay units. • No bulk density has been measured because the SG is considered appropriate as an input into the ore body model. • It was found that the 15 samples have an average SG of 1.143 g/cm3. • A low average density was calculated at 1.6 g/cm3and was the density used as an assumed density value for the Bitterwasser Main Pan. |
| Classification | • The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (ie relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the Competent Person’s view of the deposit. |
• The Bitterwasser Lithium Exploration (Pty) Ltd exploration area in the Bitterwasser Main Pan is classified as an Inferred Mineral Resource. • Where blocks bounded by sampling on at least one side, or where the down dip continuation of a block has been demonstrated by auger-hole intersections. Inferred Resource blocks are limited to the drilled area where more data sets are available and are normally the blocks with the highest density of samples. Here geological interpretation suggests that continued mineralisation is likely even where no drilling information is available. These blocks are open ended in depth. Wide spaced auger sample data is available as the only data source. • The results reflect the Competent Person’s view of the deposit. |
| Audits or reviews |
• The results of any audits or reviews of Mineral Resource estimates. | • Creo has independently verified the underlying sampling and assay data. Creo considers that given the general sampling programme, geological investigations, independent check assaying and, in certain instances, independent audits, the estimates reflect an appropriate level of confidence |
