About Aterian plc

www.aterianplc.com

Aterian plc is an LSE-listed exploration and development company with a diversified African portfolio of critical metals projects.

Aterian plc is actively seeking to acquire and develop new critical metal resources to strengthen its existing asset base whilst supporting ethical and sustainable supply chains as the world transitions to a sustainable, renewable future. The supply of these metals is vital for the development of the renewable energy, automotive and electronic manufacturing sectors that are playing an increasing role in reducing carbon emissions and meeting climate ambitions globally.

The Company entered into a joint venture agreement with Rio Tinto Mining and Exploration Limited for Rio Tinto to earn into the HCK project in southern Rwanda to explore and develop lithium-tantalum-niobium-tin mining operations. Aterian currently holds a portfolio of multiple copper-silver and base metal projects in the Kingdom of Morocco, with a total area of 897 km2. In January 2024, the Company announced the acquisition of a 90 % interest in Atlantis Metals. This private Botswana registered company holds seven mineral prospecting licences for copper-silver in the Kalahari Copperbelt and three for lithium brine exploration in the Makgadikgadi Pans region. The total licence area in Botswana is 4,486 km2.

The Company's strategy is to seek new exploration and production opportunities across the African continent and to develop new sources of critical mineral assets for exploration, development, and trading.

Director

20 September 2024

Chairman's statement

I am pleased to announce the unaudited Interim Results of the Group for the half-year ending 30 June 2024.

These accounts reflect a loss of £504,000 (2023:£858,000) arising from administrative costs; this corresponds to the Company's expenditure on overheads, operational and exploration expenses. Additional expenditure was incurred on mineral exploration in Morocco, Botswana, and Rwanda, where we are establishing a mineral trading business.

Our strategy focuses on responsibly exploring and developing critical mineral and metal resources across Africa, a region vital for a successful energy transition. The renewable energy, automotive, and electronic manufacturing sectors are currently driving the need to develop secure supply chains for critical metals. We firmly believe the long-term market fundamentals for copper are excellent and linked specifically to the anticipated growing demand for renewable energy and related transportation electrification globally.  We also believe that long term supply demand dynamics bode well for lithium.

We currently have active projects in Rwanda, Morocco, and Botswana.

Rwanda Update

Aterian, through its 100% owned Rwanda registered subsidiary, Eastinco Limited ("Eastinco"), is actively engaged in mineral exploration and developing its portfolio of critical metals in Rwanda, focusing on the country's excellent hard rock lithium potential. The Company has two partnerships exploring and developing the lithium-tantalum (+niobium) and tin opportunities hosted within numerous mapped intrusive pegmatite dykes and sills. Eastinco Limited holds a mineral trading licence issued by the authorities in Rwanda, which allows for trading mineral concentrates from internal supply and third-party producers and suppliers. We continue to slowly develop this business with a focus on minimising capital costs and risks associated with trading.

Below is a brief description of the operational HCK project. The Musasa and Dynasty projects are pending licence approvals from the Rwandan authorities.

The HCK Project

The HCK Project covers 2,750 hectares in southern Rwanda with the licence held by Kinunga Mining Ltd, a Rwanda-registered joint venture company owned 70% by Eastinco Limited and 30% by HCK Mining Company Ltd. Aterian entered an earn-in Joint Venture Agreement with Rio Tinto Mining and Exploration Ltd ("Rio Tinto") over this project in August 2023. Under this joint venture, Rio Tinto can earn up to 75% interest in the project by funding a two-stage exploration programme with total committed expenditures of US$ 7.5 million. 

A summary of activities being managed and operated by Rio Tinto is given below.

Rio Tinto's operational field teams have collected 277 rock chip surface samples from several mapping campaigns over the licence and 3,029 geochemical soil samples, with full assay results pending. Recent soil sampling has focused on tighter in-fill control over ten selected priority areas. Completing and interpreting ground magnetic and radiometric geophysical surveys and geological mapping supports this work. Planning for the initial drilling campaign is well underway, with site access and drill pad preparatory work expected to start in August 2024. The drill programme is scheduled to commence in late Q3/2024.

Elemental Altus Royalty Corp holds a 1.25% to 1.4 % (depending on the Rwandan total exploration land holding) net smelter return ("NSR") over this project.

Rwanda Metal Trading   

In July 2024, post-reporting period, the Company announced the successful completion of a metal concentrates Off-take Agreement by its Rwandan subsidiary, Eastinco Limited, with a significant international trading house. This key strategic partnership allows for the sale and distribution of Eastinco's tantalum-niobium and tin concentrate secured from Rwandan-based artisanal and small-scale mining ("ASM") companies and cooperatives, significantly enhancing the company's ability to generate revenue from aggregating and upgrading ASM concentrate supplies.

In conjunction with this Agreement, Aterian has agreed on the terms for a US$ 1.0 million maximum secured trade finance debt facility from a financial investor. This Facility is a revolving debt facility with an approximately 14.4% annual interest rate, subject to the completion of due diligence and legal documentation. The Facility will provide the Company with the necessary working capital requirements for trading operations, ensuring seamless execution and operational efficiency. Confidentiality has been agreed amongst the parties to protect our mutual commercial interests in a highly competitive environment.

Aterian's trading business model is to partner with several suppliers in Rwanda to support their mining operations by providing mining and processing equipment, capital investment, and training. The first partner projects have been identified, and the Company is now conducting additional due diligence and technical planning. Basic mineral processing systems will be installed under a lease agreement, with the development of new access tunnels into the deeper levels of the mining areas. This new infrastructure and technical support should result in an immediate uplift in production by processing existing tailings material and a longer-term sustainable production uplift from accessing the deeper mineralised structures.

Morocco Update

The Company presently holds 897 km² under licence in the Kingdom of Morocco ("Morocco"). The licences primarily target critical minerals focusing on copper and silver and are held 100% by the Company's Moroccan subsidiaries. Elemental Altus Royalty Corporation has a 2.5 % NSR royalty over each of the licences held by Aterian in Morocco.

Most of the projects occur within the Anti-Atlas region in Morocco, a region known for its significant copper deposits, which have been mined since ancient times. The Anti-Atlas Mountains are part of the Precambrian crystalline basement of Morocco. Various types and styles of mineralisation characterise them due to their complex geological history involving multiple phases of tectonic activity and magmatism. Copper is primarily found in the form of sulphide minerals such as chalcopyrite, chalcocite, and bornite with deposits associated with Neoproterozoic volcanic and sedimentary rocks, often linked to ancient volcanic-sedimentary basins and rift zones. Sedimentary-hosted copper deposits in the Anti-Atlas region of Morocco are a significant aspect of the area's geology and mining industry, with copper mineralisation often hosted in sandstone, shale, and carbonate rocks. The host formations include the Adoudounian (and Cambrian aged) dolomites and limestones, well-known for hosting copper and other metals.

The Company is currently reviewing its existing portfolio to rationalise the Moroccan project assets, whether due to geology, geography and/or lack of existing infrastructure. Additionally, we await the Moroccan government licence review and expect the addition and subtraction of some licences. The government's feedback, combined with our internal assessment will allow the Company to focus its efforts on the most highly prospective projects.

Below is a brief description of the key projects in Morocco.

The Agdz Project

The Agdz Project covers 34.46 km² and comprises a single mining licence. The project is located within the Souss-Massa-Drâa region of the Anti-Atlas Mountains of central Morocco, approximately 350 km south of the capital, Rabat, and approximately 35 km east of the city of Ouarzazate, where high-standard infrastructure and services exist, including a regional airport. Agdz lies approximately 14 km southwest of the Bou Skour copper-silver mine, with the world-class Imiter silver mine located 80 km to the northeast, both operated by Managem Group.

A scout drill programme is scheduled for Q3/2024, targeting historical copper workings, geophysical anomalies, copper mineralisation identified in reconnaissance trenching, and copper observed in outcrops during surface geological mapping. The expected outcomes from this programme will provide indications of the economic potential of the copper-silver mineralisation, improved datasets to revise the geophysical interpretation, aid in refining the geological model, confirm the style of copper mineralisation, and allow planning for additional drilling to advance the project towards a mineral resource estimation.

The lithological package at Agdz broadly consists of mostly felsic-intermediate volcano-sedimentary rocks of the Ouarzazate Supergroup with large granodiorite plutons in the north and locally conglomeratic metasedimentary sequences in the south. The units are bisected by sub-parallel NE and NW striking brittle faults and alteration zones, several of which have been historically mined for copper. A re-interpretation of the available ground-based geophysics and ground geological mapping indicates that the main prospects identified occur in a potential dilutionary jog structural setting.

Five prospects, namely Makarn, Makarn North, Amzwaro, Miniere and Daoud, have been outlined on the project based on rock chip sampling (the best of which returned grades of up to 26.5 % Cu, 448 g/t Ag, and 3.74 g/t Au), geological mapping and geophysical interpretation. These five significant Cu-Ag prospects cover an area of approximately 8 km2:

• The 2.80 km long Makarn - Markarn North prospects, with results up to 26.5 % Cu and 448 g/t Ag

• The 2.00 km long Amzwaro prospect, with results up to 4.82 % Cu and 189 g/t Ag

• The 0.15 km long Minière prospect, with results up to 14.75 % Cu and 13.8 g/t Ag

• The 0.70 km long Daoud prospect, with results up to 2.98 % Cu, 152 g/t Ag

576 m of reconnaissance trenching has been completed in 13 trenches across two of the five prospects. Results include 14.12 m at 0.65 % Cu and 36.54 g/t Ag at Makarn North and 13.70 m at 0.36 % Cu and 13.26 g/t Ag at Amzwaro.

The Tata Project

The Tata Project covers 154.4 km² and is located within the western Anti-Atlas Mountains of Morocco. It occurs 30 km south of the Company's Azrar copper-silver project. The Project is approximately 465 km south of Rabat's capital, 165 km southeast of the port city of Agadir, and 50 km southeast of the Managem Group-operated Tizert copper mine.

Carbonate-rich sediments from the Late Ediacaran to early Cambrian Adoudou Formation occur within the Project along the margins of the Palaeoproterozoic Tagragra de Tata Inlier. Exploration work on the Project has identified copper mineralisation hosted within Adoudou sediments and the younger overlying Cambrian Tata Group sediments.

The Adoudou Formation comprises sediments known to host significant sedimentary copper deposits in the Western and Central Anti-Atlas, including the Tizert mine. The Tizert deposit is considered the largest copper deposit in the Western Anti-Atlas, with resources estimated to be 57 Mt grading 1.03 % Cu and 23 g/t Ag (Managem Group).

The results, to date, indicate the presence of stratiform sedimentary copper along a strike length of 18 km, with an unexplored strike length of c.26 km within the Adoudou Formation and 9 km along the Tata Group sediments remaining untested. Exploration results from rock chip sampling have reported up to 7.02 % Cu from bedding parallel, disseminated mineralisation occurring in siltstones within the lower Adoudou Formation.

Additional mapping and sampling have occurred (results pending), including several cross-sections traversing the local stratigraphy in more detail.

The company recently acquired airborne geophysical data from the Ministry of Mines and has contracted out the re-processing of this data to an independent consultant. The area covered by the historical airborne surveys includes the Tata and Azrar projects. The results of this interpretation are anticipated to allow for more focused ground follow-up, which will include detailed geological mapping and ground-based geophysical surveys to define potential drill targets.

The Azrar Project

The Azrar Project is situated in the western Anti-Atlas Mountains. It comprises an area of 99.3 km² and is located 155 km southeast of the port city of Agadir and 45 km southeast of the Tizert copper mine.

Fieldwork has identified high-grade copper and silver from multiple locations, including 3.79 % Cu and 23 g/t Ag from an NE-SW trending fault-related breccia cutting across the project's central area. More recently, a sample collected from an 8 m thick carbonate bed with disseminated malachite observed along bedding plane surfaces and cross-cutting fractures and joints reported 4.01 % Cu with 26.9 g/t Ag, highlighting the potential for stratiform sediment-hosted copper-silver mineralisation. Additional sedimentary hosted copper mineralisation was observed from prospecting in the western area, with three individual samples collected over a strike length of 1 km reporting copper grades of 1.21 %, 0.57 % and 0.54 % Cu from Adoudounian age sedimentary sequences. Several structures hosting mineralised quartz veining and fault breccia are observed. Two samples from spoil material adjacent to old artisanal workings returned good copper and associated gold (1.19 % Cu with 0.50 g/t Au, 1.22 % Cu with 0.33 g/t Au) from the quartz-specular hematite veins. The workings are sub-vertical shafts and pits, up to 7 m deep and 2 m wide, with veins up to 1.2m wide. Another vein sample was collected 1.8 km south from the artisanal workings and returned 0.54 % Cu and 0.19 g/t Au along the same structural trend.

Additional sampling and mapping have been undertaken (with results pending), and plans include ground-based geophysical surveys, detailed geological mapping and trenching to define drill targets.

The Jebilet Est Project

This project covers 73.6 km² and lies approximately 200 km south of the capital city of Rabat, 35 km northeast of Marrakech, and 15 km from a rail line to the port of Casablanca. The Project occurs approximately 15 km east of the historic Bir N'Hass copper mine, with several known base metal and copper deposits and occurrences identified within the district.

The Jebilet Est Project is underlain by Palaeozoic metamudstones and quartzites proximal to Variscan (Hercynian)-age granite and mafic intrusive bodies. Initial reconnaissance has identified a significant network of copper-bearing veins and breccia zones. Multiple parallel quartz-carbonate veins with a general ENE orientation are mapped across the licences with the largest vein zone, up to 10 m wide, striking discontinuously for over 3.25 km. High copper grades, including 4.43 % Cu and 3.11 % Cu, have been returned from outcrop sampling, with an extensive vein system mapped in the western project area.

Additional sampling and mapping have been undertaken (with results pending), and plans include ground-based geophysical surveys and trenching to define drill targets.

The Jafra Project

The Jafra Project covers 29.0 km² in the Western Meseta of north-central Morocco, 36 km northeast of Marrakech, 35 km east of the historic Roc Blanc silver mine, and 32 km from the rail line to the port of Casablanca. The project is located on the eastern margin of an intrusive pluton within the metamorphic aureole. It hosts a historically mapped lead occurrence, coincident with apparent former artisanal mining associated with fault zones and a quartz-carbonate vein system. The Project lies 14km south of the Company's Jebilet Est Copper Project.

Reconnaissance has concentrated on two areas within the centre of the project on a prominent topographic hill, where several artisanal workings are identified. All mapped workings appear to exploit quartz veins and fault zone breccia with visible sulphide mineralisation.

Surface scree covers much of the high ground, obscuring most outcrops. However, individual structures can be traced over 100 m along strike from the workings. Several breccia zones with variable widths up to 3 m have been identified and are typically composed of roughly parallel quartz-carbonate veins and breccia. Veins range from 1 to 30 cm wide with a general NE trend, cross-cutting the host metasiltstones. Rock chip sampling has reported high-grade silver and lead values up to 170 g/t Ag, 22.2 % Pb and 157 g/t Ag, 21.2 % Pb.

Recent work has involved channel sampling across the mineralised structures and a geochemical orientation survey over the flat ground to the north of the hill to explore for hidden or blind extensions to the mineralisation identified in the old surface workings. The results of this work are pending.

Botswana Update

In April 2024, the Company announced the completion of the acquisition of a 90% interest in Atlantis Metals (Pty) Ltd, a privately owned company registered in Boswana and the holder of ten prospecting licences in Botswana. Atlantis holds a portfolio of seven strategically located copper-silver licences in the world-renowned Kalahari Copperbelt ("KCB") and three lithium brine licences in the Makgadikgadi Pans, covering a total land area of 4,486.11 km².

The Kalahari Copperbelt is one of the world's most prospective areas for yet-to-be-discovered sediment-hosted copper deposits (USGS, 2020) and hosts several large stratabound, sediment-hosted copper-silver deposits. The KCB is a northeast-trending Meso- to Neoproterozoic belt that occurs discontinuously from western Namibia and stretches into northern Botswana along the northwestern edge of the Paleoproterozoic Kalahari Craton. It is approximately 1,000 km long by up to 250 km wide. It contains copper-silver mineralisation, generally stratabound, hosted in metasedimentary rocks that have been folded, faulted and metamorphosed to greenschist facies during the Damara Orogeny. Typically, the deposits comprise stratabound disseminated to structurally controlled ore bodies 5 to 40 m thick with strike lengths ranging from 1.5 to 4 km. The main target horizon for copper mineralisation is towards the base of the D'Kar Formation, close to the contact of the underlying red beds of the Ngwako Pan Formation.

One of the Atlantis licences is situated approximately 50 km east of Khoemacau Copper Mine ("KCM") Zone 5 deposit (92.9 million tonnes grading 2.0 % Cu and 21 g/t Ag), designed to produce 60,000 to 65,000 tonnes per annum of copper and 2 million ounces per annum of silver metal in concentrate. Furthermore, the Zone 9 Cu-Ag prospect, owned by KCM, is within 30 km of this license area. Another licence is 7 km west of the KCM Banana zone, which hosts 157 million tonnes grading 0.86% Cu and 11 g/t Ag. In March 2024, MMG Limited, listed on the Hong Kong Stock Exchange, completed the acquisition of Cuprous Capital Ltd, the parent company of the Khoemacau Copper Mine, for US$ 1.73 billion. 

Atlantis holds three licences, covering a combined 2,516.93 km², which is considered highly prospective for lithium brine. The licences are located along the eastern and southern shores of Sua Pan, within the Central District, with Sua Pan comprising one of three pans forming the Makgadikgadi Salt Pans. As a means of boosting exploration investment, the Makgadikgadi Pans region has been officially declared a "Lithium Zone" by the Ministry of Mines and Energy since 2022 due to a history of known lithium brine occurrence and the emergence of new Direct Lithium Extraction (DLE) technologies capable of rendering once-thought uneconomic deposits, economic, typically having lower CAPEX and OPEX compared to conventional evaporation methods. Historical data reported in a 1980s study of the Sua Pan brines by the US Trade and Development Program indicated anomalous lithium values. The samples were collected from the northern area of Sua Pan and returned values of 103, 117, and 223 mg/l Li (note that the precise sample locations are unknown at this time).

Target generation is underway, with independent consultants acquiring and reprocessing airborne geophysical and remote sensing data for the licences.

Strategically, we aim to explore and develop the asset portfolio in joint ventures with partners with the expertise and capital to advance or eliminate the projects as prospective. Unfortunately, Brexit has resulted in the fragmentation of UK and EU capital markets, which in turn has diminished the depth and fluidity of capital flows, especially for smaller capitalisation companies.  The resulting reduction in share prices and market capitalisations has fed through sectors such as mining.  These lower valuations hamper the market's ability to invest, even while increasing the opportunity set for those companies able to identify undervalued assets.

Principal Risks and Uncertainties

The Board considers strategic, operational and financial risks and identifies actions to mitigate those risks. These risk profiles are updated at least annually. The principal risks and uncertainties can be found in the Group's risk profile analysis can be found on pages 17 to 21 of our Annual Report for the year ended 31 December 2023, available from the Aterian plc website: https://aterianplc.com/

The principal risks and uncertainties which may impact results and prospects over the second half of the year and a summary of the key measures taken to mitigate those risks are as follows:

-      Trading business

Eastinco Limited holds a metal trading licence issued by the authorities in Rwanda, which will allow for trading metal concentrates from internal supply and third-party producers and suppliers. Our trading business model is to partner with several suppliers in Rwanda to support their mining operations by providing mining and processing equipment, capital investment and training. The first partner projects have been identified, and the Company is now conducting additional due diligence and technical planning. The outcome of these procedures will have an impact on the timing and level of revenues which might be generated before the year end.

-      Rio Tinto Joint Venture

On 31 July 2023, the Company signed a definitive Earn-In Investment and Joint Venture Agreement ("Agreement") with Rio Tinto Mining and Exploration Ltd ("Rio Tinto") and Kinunga Mining Ltd ("Kinunga"). The Agreement is for the exploration and development of lithium and by-products at its HCK Joint Venture project holding the HCK licence (the "Licence") in the Republic of Rwanda.

Rio Tinto has the option to incur work expenditure of US$3 million over a two-year period ("Stage 1") to earn an initial 51% interest in the Licence. Rio Tinto will also make cash payments to Aterian, totalling US$300,000, to reimburse previous operational expenses incurred by Aterian. An initial payment of US$200,000 was made on completion of satisfactory due diligence by Rio Tinto, and an additional payment of US$100,000 will be due at the start of Stage 2.

The outcome of these procedures may impact on the prospects for and funding of this project.

-      Funding of the Group

The Group has not yet earned revenues and as at 30 June 2024 was in the feasibility, optimisation and commissioning phase of its ore processing and trading facility in Rwanda. In Morocco and Botswana, each of its assets are in the early stages of exploration and feasibility assessment. Continuing operations of the Group are currently financed from funds raised from shareholders and this will likely continue to be the case until revenue is generated from mining and/or trading and subsequent ore sales.
