Investment View

Conditional

Proceed only after ore, power, offtake and legal validation

Core Opportunity

Zimbabwe combines a globally significant chromite endowment, an established ferrochrome industry, mining skills, operating submerged-arc furnace capacity and rail access to regional ports.

Strong geology

Main Constraint

Power reliability, ferrochrome price volatility, domestic smelter bargaining power and changing rules for unprocessed mineral exports can materially weaken returns.

Power is critical

Board Recommendation

Fund staged ore-supply and metallurgical validation first. Do not commit to a standalone furnace until power and at least 10–15 years of secured feed are demonstrated.

Stage-gated entry

Preferred investment thesis: Secure or acquire an ore source, prove grade and recovery, commission modular concentration, then use an established domestic smelter through tolling or joint venture before considering proprietary furnace capacity.

2. Chrome Value Chain

Each stage has a different commercial gate.

Exploration & Mine Development→Mining: Lumpy Ore + Fines→Beneficiation: Concentrate→Agglomeration→SAF Smelting→HCFeCr / Charge Chrome→Export & Sale

Value-chain stage	Typical product	Primary commercial issue
Exploration and mine development	Chromite resource / ROM ore	Title, continuity, grade, Cr/Fe ratio and mine life
Mining	Lumpy ore and fines	Mining cost, dilution, recovery and contractor performance
Beneficiation	Washed lump / concentrate	Mass yield, recovery, water, tailings and product quality
Agglomeration	Sinter, pellet or briquette	Treatment of fines and furnace-feed consistency
Smelting	High-carbon ferrochrome / charge chrome	Power, reductants, furnace utilisation and metal recovery
Marketing and export	Ferrochrome alloy	Price formula, buyer qualification, logistics and working capital

3. Geological Setting & Ore Quality

Great Dyke chromite plus adjacent podiform and weathered deposits.

Deposit Styles

Style	Typical character	Mining implication
Seam chromite	Laterally persistent layers with variable thickness and grade	Strip or underground mining where geometry is well defined
Podiform chromite	Irregular lenses or pods, locally high grade	Dense drilling and careful grade control
Alluvial / eluvial	Weathered or transported near-surface material	Low stripping but finite and increasingly depleted
Tailings / slag	Historic fine chrome or smelter residues	Retreatment potential where metallurgy and ownership are clear

Ore-Quality Parameters

Cr₂O₃ grade: contained chromium and concentration potential.
Cr/Fe ratio: alloy chemistry and furnace value.
SiO₂ and Al₂O₃: slag volume, energy consumption and recovery.
Phosphorus and sulphur: product-quality constraints.
Lumpy-to-fines ratio: agglomeration requirement.
Liberation size: spiral, jig and magnetic-separation performance.

Investment rule: head grade alone is insufficient. Assay, mineralogy, liberation, size distribution and smelter acceptance must be evaluated together.

4. Principal Mining Districts & Corridors

District-level screening; claim ownership and current production require verification.

Corridor Attractiveness

District Database

District / corridor	Deposit character	Industry relevance
Mutorashanga / North Dyke	Predominantly underground seam mining	Established northern ore source and Zimasco centre
Darwendale–Ngezi / Middle Dyke	Surface strip and underground seam operations	Large central corridor with links to Selous and Kwekwe
Lalapanzi	Predominantly seam deposits	Long-standing district near Gweru and Kwekwe
Shurugwi–Guinea Fowl	Podiform and seam deposits	Major southern ore-supply and historic mining centre
Mashava–Mberengwa–Zvishavane	Southern Great Dyke and adjacent deposits	Potential feed corridor for Gweru, Kwekwe and southern routes
Great Dyke small-scale belt	Numerous claims and tributary miners	Flexible supply but variable title and quality control

Data limitation: no complete, current public mine-by-mine database reliably states ownership, coordinates, production, grade and reserves. Confirm through title searches, field visits, operator records and MMCZ data.

5. Existing Mining & Ore-Supply Structure

Supply Model Comparison

Supply model	Advantage	Main risk / control
Owned mine	Feed security and direct grade control	Higher capital, title risk and development time
Tribute mining	Lower owner operating burden	Contractor control, dilution, safety and reconciliation
Third-party ore purchase	Flexible volume and lower initial capital	Variable chemistry, provenance and price exposure
Long-term offtake	Secures feed without full ownership	Counterparty performance and pricing formula
JV with claim holder	Combines local title and investor capital	Governance, dilution and transferability

6. Beneficiation & Chrome Concentration

A wash plant improves product quality but does not automatically create export eligibility.

Core Process

ROM Handling→Crushing→Scrubbing→Screening→Desliming→Gravity Separation→Dewatering

Key Equipment

ROM hopper and blending pad
Crusher and screens
Scrubber / washing circuit
Spirals for fine chromite
Jigs for selected coarse fractions
Optional magnetic separation
Thickener, dewatering and water return

Validation Metrics

Representative sampling
Grade-recovery curve
Mass yield and product chemistry
Water consumption and recycle
Tailings stability and closure
Buyer specification and payment terms

Regulatory caution: concentrate export depends on current product classification, Ministry approval, MMCZ requirements and applicable statutory instruments. Base the project on domestic smelting, not an assumed permanent export exemption.

7. Ferrochrome Producers & Smelting Assets

Capacity and operating status are tagged by confidence; not all nameplate furnaces are necessarily active.

Publicly Supported Capacity / Position

Producer	Location	Publicly supported position	Confidence
Zimasco	Kwekwe	5 × 18 MVA SAFs; 180,000 tpa HCFeCr; integrated mines	High
Afrochine	Selous / Makwiro	First phase: 2 × 16.5 MVA; about 50,000 tpa; later expansion reported	Medium
Jinan-Almid / Jin An	Gweru	Operating multi-furnace alloy platform; current output requires direct confirmation	Medium
ZimAlloys	Gweru	Historic major producer under staged restart	Medium
Maranatha	Kadoma area	Registered HCFeCr producer with stated ore source	Medium

Zimasco benchmark: its integrated mines, five 18 MVA furnaces, 180,000 tpa stated capacity and rail route to Maputo demonstrate the full mine-to-export value chain already operating in Zimbabwe.

9. Logistics & Export Corridors

Kwekwe–Maputo

Proven rail route

Kwekwe → NRZ → Chicualacuala → Mozambique railway → Port of Maputo. Used by Zimasco for ferrochrome exports.

Selous / Harare–Beira

Potential road / rail

Relevant to northern and central producers, but current freight, capacity, border and port terms require validation.

Southern Zimbabwe–South Africa

Alternative corridor

Road and rail through Beitbridge to South African ports, reductants, technical services and customers.

Commercial rule: low-value ore is very sensitive to mine-to-plant distance. Site selection must balance ore haulage, power, reductants, rail, water and environmental approvals.

10. Power, Reductants & Utilities

Input Criticality

Input	Requirement	Zimbabwe-specific issue
Electricity	Stable 24/7 high-load supply	Grid reliability and tariff certainty are the principal bankability constraints
Chrome ore / concentrate	Consistent chemistry and sizing	Blend control across multiple mines
Coke / reductant	Fixed carbon and reactivity	Domestic supply exists; quality and delivered cost need testing
Quartzite / flux	Controls slag chemistry	Local quality must be verified
Water	Cooling, washing and services	Hydrology and allocation are site-specific
Electrode paste / spares	Continuous furnace operation	Import lead time and foreign-currency working capital

11. Regulatory & Institutional Framework

Product-specific rules must be reconfirmed immediately before investment.

Ministry of Mines

Mining title, policy, inspections, beneficiation and operating approvals.

Core authority

MMCZ

Mineral marketing, sales oversight, permits and market support.

Commercial gate

ZIMRA / Single Window

Tax, customs, exporter registration and certificates of origin.

Export compliance

Environmental Management

EIA, waste, emissions, tailings and compliance obligations.

Mandatory

Water Authorities

Abstraction, discharge, dewatering and water-use permissions.

Site-specific

Local Authorities & Communities

Land access, roads, services, social licence and local development.

Early engagement

12. Business-Model Comparison

Strategic Attractiveness

Business model	Capital intensity	Policy fit	Commercial assessment
Mine only; domestic sale	Low–medium	Medium	Fast entry but weak pricing power
Mine + wash plant	Medium	Medium / uncertain	Improves value but concentrate-policy risk remains
Merchant wash plant	Medium	Medium	Depends on reliable third-party ore and market
Mine + concentrator + toll smelting	Medium–high	Strong	Best balance of value capture, capital and policy alignment
Mine + own smelter	Very high	Very strong	Only with secured power, feed and offtake
Acquire / rehabilitate smelter	High	Strong	Can shorten schedule; hidden liabilities may be material

Recommended model: Mine or contracted ore supply + modular concentrator + toll smelting. Evaluate an owned furnace or brownfield smelter only after the operating case is proven.

13. Principal Risk Register

Risk	Severity	Mitigation
Power interruption or high tariff	Critical	Bankable supply agreement, load study, redundancy and captive-energy strategy
Ore grade / Cr-Fe variability	High	Drilling, bulk sampling, testwork and controlled blending
Export-policy change	High	Design around domestic smelting and obtain written approvals
Chrome / ferrochrome price volatility	High	Conservative pricing, flexible contracts and staged capital
Mine-title and ownership issues	High	Independent cadastral and legal due diligence
Water and tailings	Medium–high	Closed-loop circuit, engineered storage and hydrological study
Small-miner supply reliability	Medium–high	Quality contracts, traceability and diversified suppliers
Rail and border disruption	Medium	Dual-route logistics and inventory buffers

14. Stage-Gated Investment Roadmap

Stage	Indicative purpose	Decision gate
0–3 months	Build verified mine/smelter database; engage Ministry, MMCZ and producers	Select two ore corridors and two toll-smelting partners
3–9 months	Title review, mapping, drilling, bulk sample and wash tests	Prove grade, recovery, mine life and legal control
6–12 months	Ore contracts, smelter trials, power/logistics quotes and buyer discussions	Demonstrate positive margin under downside pricing
12–24 months	Develop mine, modular plant, water and tailings systems	Produce consistent, smelter-accepted concentrate
24+ months	Assess furnace or smelter acquisition after operating proof	Proceed only with secured power, feed and offtake

Final conclusion: Zimbabwe is technically capable of supporting the complete chrome-to-ferrochrome chain. The investable challenge is commercial integration—power, feed consistency, logistics, policy compliance and pricing must work simultaneously.
