Mr Matthew Allen, Chief Financial Officer at Hastings Technology Metals Limited, details the abundance of rare earth elements at the Yangibana Project, specifically that of neodymium and praseodymium.<\/h2>\n

Hastings Technology Metals Ltd (Hastings; listed on the Australian Securities Exchange, ASX:HAS) discovered the Yangibana Project in 2014, hosting economic proportions of vital rare earths. The unwavering vision of our Executive Chairman, Mr Charles Lew, to commercialise these rare earths as an enabler of the decarbonisation revolution has continued since the discovery. The Yangibana Project is rich in the rare earth elements<\/a> neodymium (Nd) and praseodymium (Pr), collectively referred to as NdPr, which are becoming essential for the manufacture of permanent magnet motors that are critical components of electric vehicles (EVs), wind turbines and other technologies leading the decarbonisation revolution.<\/p>\n

The Yangibana Project is situated in the remote outback of Australia, on Thiin-Mah Warriyangka Tharrkari Jiwarli (TMWTJ) Country, approximately 270km North East of Carnarvon, Western Australia. Here lies ancient granite geology overlain by a dendritic pattern of tree-lined rivers and creeks and a gentle rocky topography with gnarly shrubs adapted to the harsh conditions of a semi-arid environment. This land was historically a meeting place of several nomadic Aboriginal tribes. While no longer residing in the area, their modern-day relatives still have strong connections to the country.<\/p>\n

The Hastings Executive Chairman has been adamant that our team work closely with the traditional owners and formalised this relationship with a voluntary Project Native Title (NT) Agreement in November 2017. One of the elders, Mr Peter Salmon, is the last language speaker for the TMWTJ people and holds extensive knowledge of the area. In addition to meeting the requirements of the NT Agreement, Hastings is providing financial support to document Peter\u2019s language and knowledge base, which may have been lost without our help. Hastings continues to conduct yearly cultural heritage surveys that bring some of the younger generations back onto the country to learn from the elders, the specialist archaeologists, and anthropologists and familiarise themselves with their ancestral lands. We have also had a continual consultation process with the TMWTJ people at regular meetings and cultural heritage surveys to discuss the Yangibana Project. Hastings annual mineral exploration programmes have also provided employment opportunities for the traditional owners.<\/p>\n

Our mineral exploration programmes have revealed that the Yangibana Project holds one of the richest concentrations in the world of NdPr within the basket of 17 rare earth elements (REE). Yangibana\u2019s REE is hosted in curtains of ironstone surrounded by granite bedrock. These curtains extend over areas up to 17km long and in multiple locations. The total tenement area measures 650km2<\/sup>. To date, exploration and drilling work has only been conducted on approximately 55km2<\/sup>, representing 27 million tonnes of mineral resource and 16.7 million tonnes of ore reserves. Tremendous potential exists for future growth in this area.<\/p>\n

The high concentrations of NdPr also likely make this mining project one of the most efficient rare earth mining projects in the world, i.e., less consumption of reagents, fewer water requirements and less energy per tonne of ore are used to mine and process the rare earth elements. Benchmarking shows the greenhouse gas emissions intensity of the Yangibana Project is one of the lowest in the world for any rare earths mining project. And this will only get better as we implement our Carbon Reduction Transition Plan to do our part in reducing greenhouse gas emissions.<\/p>\n

Exploration and processing at the Yangibana Project
\n<\/strong><\/h3>\n

Mineral exploration programmes to date have formed the foundation for developing the Yangibana Project. The 15-year life of the mine is proven from ongoing yearly drilling programmes and has the potential for significant growth in the future. In fact, a further mineral exploration programme is currently underway. We have only just touched the surface of what appears to be a significant volume of REE at Yangibana that will contribute approximately 6-8% of global demand requirements once in production.<\/p>\n

In addition to mineral exploration, our metallurgists have also undertaken detailed and extensive laboratory-based test work and two pilot plant programmes to determine how best to concentrate the rare earth elements in preparation for the next step in the supply chain, which is then to separate the rare earth elements. As a result of the metallurgical programmes, a process plant has been designed and engineered, including a beneficiation and a hydrometallurgical process. The beneficiation process involves crushing, screening and flotation. Over 95% of the waste material is removed during this step for disposal in a tailings storage facility. The resultant beneficiation concentrate is then fed into a hydrometallurgical plant, which involves cracking the beneficiation concentrate using heat and acid, and then putting it through a milder series of chemical reactions in water to remove water-soluble impurities. Additional waste material is removed during the hydrometallurgical process for disposal in a tailings storage facility. As a result of the processing, we can produce high-quality mixed rare earth carbonate (MREC) products with the highest NdPr content in a MREC product compared to our peers in the world.<\/p>\n

Engineering design of the mining and associated waste rock landforms, process plant and tailings storage facilities and associated mine site infrastructure, including a 300-person accommodation village, power station, borefield and aerodrome, has been completed and formed the basis of a definitive feasibility study (DFS).<\/p>\n

Yangibana Project economics and ESG
\n<\/strong><\/h3>\n

Our proven REE reserves and a DFS show that the Yangibana Project has strong mine economics that is attractive for long-term thematic investors based on the following:
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 16.7 Mt of ore reserves;
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Up to 52% NdPr to Total Rare Earths Oxide (TREO) ratio (life of mine average is 37% NdPr: TREO ratio, which is double the world average);
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 After beneficiation, an upgrade in concentration of REE by up to 25 times;
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Average NdPr production: ~3,400 tonnes per annum (representing 6-8% of the global NdPr demand in 2024\/2025);
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Low capital expenditure (CAPEX): A$516m (includes contingency);
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 NPV: A$549m; and
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 IRR: 21.1%.<\/p>\n

As demand for neodymium sintered magnets increases, demand for NdPr will follow in tandem. This is reflected by a NdPr oxide price that has doubled in the last 12 months and is now trading at above US$120\/kg (source: Asian Metals, 22 November 2021). The primary driver for the price rise is persistently strong demand for EVs and wind turbines. Independent commodity market analysts like CRU and Roskill predict a sizeable supply gap to emerge in the next three to five years, which coincides with our timeline for the first production scheduled for 2024.<\/p>\n

In addition to being blessed with an exceptional ore body and favourable project economics, Hastings has secured offtake agreements for ~70% of production over ten years with thyssenkrupp (a German industrial conglomerate) and Skyrock Baotou (a permanent magnet producer in China). The company has also signed a Master Agreement with Schaeffler and a Memorandum of Understanding with a European tier 1 automotive component supplier. The latter of these two agreements provide for Hastings to work with these European companies for a long-term supply of our MREC into a European mine to magnet supply chain that is being developed with the support of the European government agency, ERMA (European Raw Materials Alliance). Both Schaeffler and thysennkrupp have excellent sustainability credentials. Hastings are in alignment with European regulations in recognising the importance of sustainability along the supply chain.<\/p>\n

Formal credit applications for project finance are advanced, with the first drawdown expected in late 2022. Specifically, Hastings is actively engaged with:

Australian mining projects are attractive to international investors due to low ESG (Environmental, Social, Governance) risk, a geology that is rich in critical minerals, access to renewable energy resources such as solar and wind, and a skilled workforce. The attraction of European customers and financiers to our product and project respectively is further strengthened by our location and sustainability credentials. Hastings\u2019 inaugural sustainability report was released in 2021 with positive feedback received from our stakeholders.<\/p>\n

In addition, Australia has some of the most stringent environmental approvals processes globally, which often take two to three years to obtain. This reassures investors that our project has been developed to the highest environmental standards. The Australian approvals requirements occur at all levels of government (Commonwealth, State, and local government), require many detailed environmental surveys and assessments, and often involve at least a public advertisement and consultation process for each approval. The Western Australian approvals submissions require the involvement of multiple government departments, each with different jurisdictions and perspectives. The replication of information and all the \u2018green tape\u2019 demonstrates that the environmental assessment process for the project has been thorough. Hastings is pleased to announce that the base case for the Yangibana Rare Earths Project has received all approvals and are well advanced for the Yangibana Expansion 1 Project.<\/p>\n

Enforcing health and safety
\n<\/strong><\/h3>\n

Despite strict regulatory requirements at Commonwealth and State levels of government, the association of naturally occurring radioactive materials has been highlighted in the media for rare earths mining in general due to a historical legacy of illegal mining in China and irresponsible environmental management practices. Thorium and uranium co-occur with the rare earth elements in the ore body. Their concentrations vary from one mine site to another and are unique to the ore body. At the Yangibana Project, uranium concentration alone would not be considered radioactive. However, thorium and its decay products result in an ore body that is considered to have low-level radioactivity. During the hydrometallurgical processing, the thorium is separated from the rare earth elements and is concentrated. The MREC product is not classified as radioactive. A very small portion (less than 5%) of tailings are radioactive, which come from the hydrometallurgical plant, which is nevertheless regarded as low. The beneficiation plant produces the other 95% of tailings and is not considered radioactive.<\/p>\n

The risk of exposure to radioactivity by our workforce, the public and the surrounding environment are orders of magnitude lower than the prescribed dose limits set by the International Commission on Radiological Protection. The storage of tailings has been a significant focus of our work, specifically the hydrometallurgical tailings storage facility (TSF) containing low levels of thorium. To date, over 20 studies have informed the design of the TSF, including waste characterisation (physical and chemical), geochemical analysis of tailings solids and liquids, seepage modelling, erodibility studies, landform evolution modelling (over 1,000 years), leach testing (drying and wetting to represent seasonal influences), cover design to ensure radon does not emanate post-closure, radiation impact assessment, ecological studies, hydrology and hydrogeology and ecotoxicology assessments.<\/p>\n

The most notable outcomes from the studies include:
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 An impermeable granite layer under the TSFs that prevent vertical seepage;
\n\u2022\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Tailings pore water has been demonstrated to be non-radioactive despite the tailings stream, primarily due to thorium not being water-soluble; and<\/p>\n
