The New Shares will rank pari passu in all respects with the existing Ordinary Shares.

As the Company does not hold any shares in treasury, this figure may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company following Admission under the FCA's Disclosure Guidance and Transparency Rules.

About Jangada Mines Plc

Jangada is a natural resource development company listed on AIM of the London Stock Exchange (AIM:JAN) with assets in Brazil. It is led by a team with deep industry, financial and in-country experience, and has a dual growth strategy to:

•           Advance its portfolio projects including the high-grade Paranaíta Gold Project and the 100%-owned Pitombeiras vanadium titanomagnetite Project

•           Utilise its proven in-country and geological expertise to identify/acquire additional projects that it can rapidly advance to build value for shareholders.

The Company is currently focussed on the 7,211-hectare Paranaíta Gold Project, which is a gold-rich porphyry-epithermal system with extensive historical data, artisanal mining history and structural similarities to nearby producing high grade gold deposits. The Board believes that the alignment of widespread gold mineralisation, coincident geochemical anomalies, and their correlation with magnetic structures indicated on the results of the exploration conducted on the Paranaíta Gold Project thus far strongly indicates the potential for a large-scale gold deposit. The Company is currently conducting exploration and development work to test multiple gold-bearing structures that remain open in all directions, with the objective of rapidly scaling up the resource base and unlocking the broader potential of the Paranaíta Gold Project.

The Company also owns 100% of the Pitombeiras vanadium titanomagnetite (VTM) project in the state of Ceará, Northeast Brazil. In April 2022, the Company published a headline 100.3% post-tax Internal Rate of Return ('IRR'), and a US$96.5 million post-tax Net Present Value ('NPV') (8% discount rate) with a 13-month payback for the Project. The report demonstrated Pitombeiras' potential to be a profitable VTM producer with no geological, economic, or legal impediment to proceeding to production.

Additionally, Jangada has a 3.6% investment in Fodere, a UK minerals technology company, which has developed new and innovative commercial processes and applications in extractive metallurgy, to extract titanium dioxide, vanadium pentoxide and other valuable products from low-grade ores and waste stockpiles.
