Kabete Project Update: Processing Licence Granted, Gold Recovered During Commissioning and Advanced Micro-Seismic Programme Commences

Amigo Resources PLC (LSE: AMGO) is pleased to provide a comprehensive operational update on the Kabete Project in Tanzania, where the Company has achieved several important milestones across both exploration and processing activities.

Highlights

• As announced by the Company on 14 May 2026, Processing Licence No. PCL 0356/2026 was granted in respect of the Kabete Project, representing an important milestone.

• Commissioning and pilot-scale processing activities commenced.

• Approximately 1.1 kilograms of gold recovered during initial commissioning activities.

• Royalties, inspection fees and statutory payments made in accordance with Tanzanian mining regulations.

• First phase of advanced micro-seismic imaging completed over priority exploration targets identified through geochemical programmes.

• Three-dimensional subsurface modelling has identified multiple interpreted geological and structural anomalies, including a significant vertically extensive structural feature.

• Preliminary interpretation indicates encouraging correlation between micro-seismic results and previously identified geochemical target areas.

• Expansion of the micro-seismic programme planned across additional targets generated from the Company's broader geochemical database.

• Processing facility forms part of the Company's strategy to establish regional mineral processing hubs within Tanzania.

Operational Update

The Company notes that Processing Licence No. PCL 0356/2026 has been granted in respect of the Kabete Project, representing an important milestone in advancing the Company's strategy of integrating exploration activities with localised mineral processing capabilities.

Following the grant of the licence, commissioning and pilot-scale processing activities commenced at site. Material sourced from exploration, evaluation activities and historical workings within the project area has been processed through the Company's facilities. To date, these commissioning activities have resulted in the recovery of approximately 1.1 kilograms of gold.

The recovered gold has been processed through the applicable regulatory framework in Tanzania, with all relevant royalties, inspection fees and statutory payments made to the Government of Tanzania.

Exploration Programme Advancement

In parallel with the commissioning programme, the Company has successfully completed the first phase of advanced micro-seismic imaging across a priority target area identified from previous geochemical programmes.

The survey forms part of Amigo's integrated exploration workflow, combining geochemistry, geological interpretation and advanced geophysical techniques to improve target definition and prioritisation.

Preliminary interpretation of the micro-seismic data has identified multiple coherent geological and structural features, including a significant vertically extensive structural conduit together with several shallow anomalous zones that may represent favourable geological environments for mineralisation.

The Company is currently integrating the micro-seismic results with its existing geochemical datasets, including gold, arsenic, copper, nickel and chromium anomalies, together with geological mapping, structural interpretations, historical workings and artisanal mining activity.

The current survey represents only the first stage of a broader regional programme. Additional micro-seismic coverage is now being planned across further priority targets generated from the Company's extensive geochemical database, with the objective of developing a portfolio of drill-ready targets through integrated geological, geochemical and geophysical analysis.

Strategic Development

The Kabete processing facility forms part of Amigo's broader strategy of establishing scalable mineral processing hubs capable of supporting both Company-owned projects and, subject to regulatory approvals, material from third-party operators.

The Company believes this integrated exploration and processing model has the potential to accelerate project development timelines, improve value retention within Tanzania and create additional opportunities across its broader portfolio of gold and critical mineral assets.

Chairman's Comment

Craig Ransley, Executive Chairman of Amigo Resources PLC, commented:

"The grant of Processing Licence PCL 0356/2026, the successful recovery of gold during commissioning and the commencement of advanced micro-seismic surveying represent important milestones for the Kabete Project.

We are now executing a strategy that combines exploration, advanced targeting technologies and processing infrastructure development. The initial micro-seismic results have identified several encouraging subsurface targets which correlate with areas highlighted through our earlier geochemical programmes.

Importantly, this survey programme has only recently commenced. We have a substantial pipeline of geochemical targets across the wider project area and intend to progressively expand micro-seismic coverage across additional priority zones. By integrating geochemistry, structural interpretation and micro-seismic imaging, we believe we can significantly improve target generation and drill targeting efficiency.

At the same time, the commissioning of the Kabete processing facility demonstrates the practical implementation of our regional processing hub strategy. We look forward to providing shareholders with further updates as exploration, commissioning and development activities continue.

As previously announced, we continue to assess a number of preliminary opportunities outside the ordinary course of business in the mining sector, any of which could develop into a reverse takeover. We will update the market as required, but there can be no assurance that a reverse takeover will take place."

Next Steps

• Expand micro-seismic coverage across additional geochemical target areas.

• Complete integrated interpretation of geological, geochemical and geophysical datasets.

• Prioritise targets for trenching and drilling.

• Continue commissioning and optimisation of processing facilities.

• Advance exploration and development activities across the wider Kabete Project and broader Tanzanian licence portfolio.

Important Notice & Caution Regarding Forward-Looking Statements

The gold recovered and reported in this announcement arises from commissioning and pilot-scale processing activities only. The results should not be interpreted as evidence of a Mineral Resource, Ore Reserve or sustainable commercial production under the JORC Code or any equivalent reporting standard.

The anomalies identified by the micro-seismic survey are preliminary exploration targets based on geophysical interpretation. The presence of an anomaly does not necessarily indicate the presence of economic mineralisation. Further exploration, including drilling and analytical testing, will be required to determine the nature and significance of these features.

This announcement is not intended to, and does not, constitute or form part of any offer, invitation, or the solicitation of an offer to purchase, otherwise acquire, subscribe for, sell, or otherwise dispose of, any securities, or the solicitation of any vote or approval in any jurisdiction, pursuant to this announcement or otherwise.
