Tyranna Resources has signed a binding earn-in agreement covering the 830 km² Coola Rare Earths and Niobium Project in Angola, with two carbonatite-bearing intrusions already mapped. The deal remains conditional on renewal of the project tenement, while a proposed 500 million-option grant adds a significant shareholder-approval question.
- Up to 70% interest in Coola Mining LDA
- 830 km² Angolan project with four alkaline intrusions
- Two mapped intrusions contain carbonatite components
- US$2.6 million earn-in expenditure plus US$100,000 upfront
- 500 million management options proposed, subject to approval
Tyranna Builds a Larger Angolan Critical Minerals Position
Tyranna Resources Limited (ASX:TYX) is seeking a 70% interest in an 830 km² rare earths and niobium project in central Angola, giving the small-cap explorer a new exposure to metals associated with carbonatite and alkaline-intrusion systems. The Coola Project sits about 60 km northwest of Huambo and contains four formally described alkaline intrusions, two of which have mapped carbonatite components.
Under the agreement signed on 28 September, Tyranna’s wholly owned subsidiary Luvulu (Mauritius) Limited will pay US$100,000 within seven days and spend a further US$1.5 million over two years to earn 50% of Coola Mining LDA. A further US$1 million of permitted expenditure over the following two years would lift its interest to 70%.
Tenement Renewal Remains the Immediate Gate
The transaction is not yet complete. Conditions include regulatory approvals and receipt of the renewed prospection title from Angola’s Ministry of Mineral Resources, Oil and Gas. Tyranna said an approval letter was received on 21 July 2026, but the renewed tenement itself remains a condition precedent.
The title is already annotated for rare earths minerals and comes with existing geochemical and geophysical datasets. Tyranna’s consultants are now integrating those datasets, prioritising targets and planning orientation fieldwork. The company has not disclosed a resource, reserve, feasibility study, production timetable or economic assessment for Coola, leaving the project firmly at the exploration stage.
Pensana Link and Local Shareholder Arrangements
Coola Mining LDA is currently 90%-owned by SBLRTHS Unipessoal Lda, a wholly owned subsidiary of London-listed Pensana, while continuing local shareholders collectively retain 10%. Those local shareholders would be free carried through completion of a feasibility study. After that point, they would need to fund their share of the project or face dilution or a sale process under the agreement.
The structure also recognises substantiated prior Coola loans of up to US$1.63 million. Those debts would be repaid only from project revenues after positive free cash flow is achieved and would carry no interest, according to the announcement.
500 Million Options Put to Shareholders
Alongside the project deal, Tyranna proposed 500 million unquoted options for directors, senior officers and key management, with shareholder approval required at the annual general meeting. The options are split into 190 million at a $0.005 exercise price expiring in August 2028, 190 million at $0.0075 expiring in August 2029 and 120 million at $0.01 expiring in August 2030.
If every option were exercised, Tyranna would receive $3.575 million in fresh Australian-dollar capital and issue an equivalent 500 million shares, subject to the relevant approvals and exercise decisions. That creates a potential funding source for exploration, but also a material future expansion of the share count that shareholders will need to weigh at the meeting.
Davide Bosio has been appointed non-executive chairman, with Joe Graziano remaining on the board as a non-executive director. The next hard evidence for the Coola thesis will be less about the geological story and more about whether the renewed title arrives, Phase 1 begins and fieldwork converts the inherited datasets into drill-ready targets.
Bottom Line?
Coola offers Tyranna a sizeable rare earths and niobium footprint at a staged cost, but the investment case still depends on tenement renewal, exploration results and shareholder approval of a potentially dilutive option package.
Questions in the middle?
- When will the renewed Angolan prospection title be issued and the Phase 1 programme formally commence?
- Can the existing geophysical and geochemical data define targets strong enough to justify further spending?
- How will shareholders assess the 500 million options against the project’s early exploration stage and future funding needs?
