Tanzania Mineral Development Portfolio

Mkomazi & Keta

Evaluating mineral development opportunities across bauxite, gold, base metals and gemstones in Tanzania.

ASTRA Group’s Tanzania portfolio brings together two identified areas of mineral opportunity, with a focus on understanding geological potential, technical requirements and pathways towards responsible development.

01 | PORTFOLIO OVERVIEW

Two Opportunities. One Mineral Development Portfolio.

ASTRA Group’s Tanzania mineral development portfolio comprises two identified areas of opportunity: Mkomazi and Keta.

Each location presents a different mineral focus and an opportunity to evaluate resources within Tanzania’s broader mineral sector.

Mkomazi is focused on the potential of bauxite resources, an important industrial mineral used in aluminium production.

Keta represents a broader multi-mineral exploration opportunity involving gold, base metals and gemstones.

Both opportunities require additional geological definition, technical assessment and project-specific verification before their development potential can be established.

Our approach is centred on understanding the resource, establishing technical confidence and identifying commercially viable development pathways.

Mkomazi Bauxite Opportunity

Evaluating the Potential of Bauxite Resources.

Mkomazi represents ASTRA Group’s identified bauxite opportunity in Tanzania.

Bauxite is the primary raw material used in aluminium production and plays an important role in global industrial supply chains. Its applications extend across construction, transportation, packaging and manufacturing.

The opportunity is centred on assessing the geological characteristics of the identified area and understanding the potential quality, extent and development requirements of the mineral resources.

Further geological investigation and technical evaluation are required to establish the commercial and development potential of the opportunity.

Mkomazi is presented as an identified opportunity. It is not a confirmed producing bauxite mine, and no resource estimate has been established.

01 —

Mineral Focus

Bauxite, the principal ore used in the production of alumina and aluminium.

02 —

Technical Evaluation

Geological investigation to establish resource characteristics, mineral quality and extent.

03 —

Industrial Relevance

Aluminium applications across infrastructure, automotive, transportation and packaging.

03 | KETA, TANZANIA

Keta Exploration Opportunity

Exploring a Broader Range of Mineral Opportunities.

Keta represents ASTRA Group’s multi-mineral exploration opportunity in Tanzania.

The opportunity involves the assessment of different mineral categories, including gold, base metals and gemstones.

These mineral groups have distinct geological characteristics, industrial applications and market considerations. Their identification provides a foundation for further geological investigation and technical evaluation.

The next stage involves understanding the mineralisation characteristics of the identified targets and determining the technical requirements for potential future development.

01 — Gold

A precious metal with applications in jewellery, investment and specialised technology. Further geological investigation is required to establish the nature and extent of any gold mineralisation.

02 — Base Metals

Industrial metals supporting infrastructure, manufacturing, electrical systems and industrial development. Target-specific mineral identification and evaluation remain necessary.

03 — Gemstones

Potential gemstone resources serving jewellery and specialised gemstone markets, subject to geological verification and quality assessment.

04 | OUR DEVELOPMENT APPROACH

From Mineral Opportunities to Defined Projects.

ASTRA Group’s approach to the Tanzania portfolio focuses on building a stronger understanding of geological potential and identifying the requirements for responsible mineral development.

The evaluation process is structured around five key areas.

01

Geological Mapping and Field Assessment

Conduct geological mapping and field assessments to understand the characteristics of the identified areas.

02

Mineralisation and Sampling Evaluation

Assess available geological information and evaluate sampling results where available.

03

Technical Characterisation

Establish the technical characteristics of identified mineral targets and determine the additional work required.

04

Mineral Rights and Regulatory Verification

Verify applicable mineral rights, tenure arrangements and regulatory requirements.

05

Development Feasibility

Evaluate the technical, commercial and operational considerations for potential future development.

05 | STRATEGIC IMPORTANCE

Supporting ASTRA's Regional Mineral Development Strategy.

Tanzania’s mineral sector offers opportunities across industrial minerals, precious metals and gemstones.

The Mkomazi and Keta opportunities allow ASTRA Group to evaluate different mineral categories within one national portfolio, supporting a broader approach to regional mineral development.

By examining industrial mineral potential alongside precious metals and gemstone opportunities, ASTRA aims to identify projects that may offer suitable technical and commercial development pathways.

01

Mineral Diversification

Evaluating opportunities across industrial minerals, precious metals and gemstones.

02

Regional Development

Supporting ASTRA’s wider mineral development interests across East and Southern Africa.

03

Selective Project Development

Prioritising opportunities based on geological evidence, technical requirements and commercial viability.

06 | PROJECT OUTLOOK

Progressing Towards Technically Defined Opportunities.

ASTRA Group’s immediate focus in Tanzania is to establish a clearer understanding of the geological potential and development requirements of the Mkomazi and Keta opportunities.

Further technical definition, verification of applicable mineral rights and assessment of development feasibility will be important in determining the next steps for each opportunity.

The portfolio will be progressed through a measured evaluation process, with future development decisions informed by geological evidence, technical findings, regulatory requirements and commercial considerations.

“Building a foundation for informed mineral development through geological understanding, technical evaluation and responsible project planning.”
