$5m - U.S.-Africa Strategic Investment Application

28 September 2026

NEOTERRA GROUP PLC

("NeoTerra" or the "Company")

US$5 Million U.S.-Africa Strategic Investment Program Application

NeoTerra Group Plc (LSE: TERA) (OTCQB: ANRCF), the African critical minerals exploration and development company, is pleased to announce that it has identified a strategic opportunity to expand the size and scope of the Monte Muambe fluorspar project and has submitted an application for a US$5 million grant under the U.S.-Africa Strategic Investment Program (the "Program") to support the assessment of this opportunity.

The Company is currently progressing the development of a 50,000 tonnes per annum fluorspar mining operation at Monte Muambe Project.

The Board now believes there is a strategic case to assess a larger-scale fluorspar operation, supported by an increased mineral resource at Monte Muambe. Establishing a larger resource and feedstock base could, in turn, support additional downstream processing and value addition in Mozambique.

Accordingly, the Company's US$5 million funding application encompasses:

·    additional resource drilling aimed at increasing the Monte Muambe fluorspar Mineral Resource from the current 716,000 tonnes of CaF₂ contained to a level of 4 million tonnes CaF₂, which will provide the opportunity to increase the production capacity and/or the life of mine;

·    a regional fluorspar and fluorine market study, including a detailed assessment of potential additional fluorspar resources and feedstock sources in Mozambique; and

·    a conceptual feasibility study to assess the potential viability of a hydrofluoric acid production facility in Mozambique, building on identified feedstock from Monte Muambe.

The application and the proposed programme do not change the timeline of the ongoing scoping study for the 50,000 tonnes per annum operation currently being finalised. The environmental permitting process for the mining operation has now started.

The proposed programme is aligned with Mozambique's ambitions to increase domestic value addition from its mineral resources and, more broadly, with regional efforts to develop African mineral value chains.

The U.S.-Africa Strategic Investment Program is administered by the U.S. Department of State's Bureau of African Affairs. The Program has estimated total funding of US$500 million, with individual awards ranging from US$5 million to US$50 million. It is focused on promoting market-based, private sector-led growth in sub-Saharan Africa and to facilitate investment in African critical mineral supply chains, including by US companies.

The application builds on NeoTerra's existing relationship with the U.S. Government in connection with Monte Muambe. As previously announced, the Company has already secured a US$1.875 million grant from the U.S. Trade and Development Agency ("USTDA") to advance the rare earths component of Monte Muambe through the prefeasibility stage.

In parallel, NeoTerra continues to pursue strategic partnerships and potential funding opportunities for the gallium component of the Monte Muambe project, with a particular focus on US-aligned parties seeking secure and responsible sources of critical raw materials.

Cédric Simonet, CEO of NeoTerra, commented:

"Our current development plan provides a clear route towards an initial 50,000 tpa fluorspar operation at Monte Muambe. We now see an opportunity to build on this foundation, in a modular fashion, and assess the potential for a broader development.

"By increasing the Monte Muambe MRE and assessing additional sources of fluorspar feedstock across the region, we want to determine whether sufficient scale exists to support downstream hydrofluoric acid production in Mozambique.

"The grant application is in line with our objective of securing solid strategic partnerships and non-equity-dilutive funding for Monte Muambe and, if successful, will allow us to assess and de-risk this expanded opportunity while we continue to progress the initial 50,000 tpa fluorspar development."
