The full model
How Mine Contribo Works
A project-based, escrow-secured, revenue participation model — built for the realities of African mining.
The problem we solve
Mining projects across Zimbabwe and Africa often stall not from lack of merit, but from lack of structured capital. Private financing arrangements are common — but they are typically informal, underdocumented, and leave contributors fully exposed when plans change or operations face difficulty.
Mine Contribo bridges that gap. Every project on the platform has been reviewed before listing, every rand or dollar is held in a dedicated escrow account, every drawdown requires verified evidence, and every contributor has a documented floor below which their return cannot fall.
Escrow-secured
Funds ringfenced per project, released only against evidence
Contributor-defined floor
You set the minimum return you'll accept before committing
Project reserve fund
Every project holds a reserve equal to the funding sought
A project is listed on the platform
A mining company or operator approaches Mine Contribo with a project that requires funding. Before anything is published, the project goes through our internal review process:
- Full project plan submitted — operational milestones, cost breakdowns, and revenue basis (whether historical from an operating project, or projected for one approaching production).
- Funding requirement defined — the total amount sought is fixed. For example: a gold processing operation in Zimbabwe's Midlands Province requiring $90,000 to commission a second milling unit.
- Return pool declared — the project owner specifies the percentage of revenues set aside for contributors over a defined term. For example: 50% of revenues for two years. This is fixed before listing and cannot be changed after contributors commit.
- Reserve fund condition accepted — the project owner agrees that once the project becomes profitable, it will set aside a reserve equal to the total funding sought. This is a non-negotiable condition of listing. See Step 4 for how this protects contributors.
Important
This is not a crowdfunding free-for-all. Every project on Mine Contribo has been reviewed and has agreed to binding terms before contributors see it. Where revenue figures are projected rather than historical, this is clearly disclosed — and risk warnings apply.
Contributors review and allocate
Once listed, registered contributors can review the project's full documentation — its funding requirement, declared return pool, revenue basis, term, and risk disclosures — and choose to allocate funds.
Each project stands alone. There is no pooling across projects — if you contribute to a chromite operation in Mashonaland West, your money goes to that project and nothing else.
Your contribution is expressed as a percentage of the total funding requirement. Contribute $18,000 to a $90,000 project and your allocation is 20% — and your share of every return pool distribution will be 20% for the full term.
Setting your acceptable return range
At the point of committing, each contributor sets an acceptable return range — a floor and a ceiling. This is personal to each contributor, documented before funds leave escrow, and forms part of the binding contributor agreement.
Your ceiling
Your full proportionate share of the declared return pool — the best-case outcome if the project performs to or beyond projection.
Example: 20% of a $400,000 return pool = $80,000
Your floor
Capital recovery — your original contribution amount. The minimum you will accept. You will not lose your capital.
Example: 20% contribution = floor of $18,000
All funds are held in a dedicated project escrow account — ringfenced from Mine Contribo's own operations and from every other project on the platform — from the moment of commitment until each drawdown is authorised.
Funds are released only against evidence
This is the core operational protection Mine Contribo provides.
The mining company does not receive a lump sum. Funds are released in tranches, tied to verified milestones. Each drawdown request must be accompanied by supporting documentation before any release is authorised from the escrow account.
Supplier invoices
Equipment, materials, and contractor costs
Permits & licences
Regulatory approvals and environmental certificates
Operational reports
Production records and milestone completions
Contributors are never simply trusting a promise. Every release of funds corresponds to something verified happening on the ground. No evidence, no release.
Returns are distributed. The reserve protects your floor.
Mining is not predictable. Mine Contribo's model is built for that reality.
The declared return pool
Before listing, the project owner declares a return pool — a fixed percentage of revenues allocated to contributors over an agreed term. This is documented and cannot change after contributors commit.
What happens when production falls short
The same project produces $250,000 in a difficult year instead of $400,000. The contributor pool for that year is $125,000 instead of $200,000. Contributors receive their proportionate share of what the project actually produced.
| Contributor | Contributed | Allocation | Ceiling (full pool) | Floor | Actual return | Within range? |
|---|---|---|---|---|---|---|
| A | $45,000 | 50% | $200,000 | $45,000 | $62,500 | Yes |
| B | $18,000 | 20% | $80,000 | $18,000 | $25,000 | Yes |
| C | $18,000 | 20% | $80,000 | $18,000 | $25,000 | Yes |
| D | $9,000 | 10% | $40,000 | $9,000 | $12,500 | Yes |
| Based on: Project sought $90,000 · Projected annual revenue $400,000 · Return pool 50% / 2 years · Actual production year: $250,000 · Contributor pool distributed: $125,000 | ||||||
All four contributors received returns above their floor — within their acceptable range — despite the project underperforming its projection by 37.5%. The reserve fund was not needed.
The project reserve fund — your last line of protection
Every project listed on Mine Contribo must, once profitable, set aside a reserve equal to the total funding sought — $90,000 in the example above. This reserve is held separately and cannot be accessed by the project owner or Mine Contribo for the duration of the contributor relationship.
If production falls so severely that a contributor's proportionate share of the return pool drops below their floor, the reserve fund bridges the gap — returning their original contribution. Contributors do not lose their capital.
If the project succeeds
The contributor term concludes. The reserve is returned to the project owner in full — minus Mine Contribo's service fee. The project owner has lost nothing except a temporary restriction on those funds and a fee on completion.
If returns fall short
The reserve bridges any shortfall between actual returns and each contributor's floor. Contributors receive at least their original contribution back, regardless of how the project performed.
Why the reserve fund is Mine Contribo's structural differentiator
It imposes a real, pre-agreed obligation on the project owner — not a promise, but a condition of accessing the platform. A project owner who cannot or will not commit to holding a reserve equal to the funding they are seeking is signalling that their confidence in their own project is limited. Mine Contribo's platform is not available to them.
What this is — and what it is not
What Mine Contribo is
- A project-based revenue participation platform — contributors take a defined stake in a specific project.
- A structured, escrow-backed mechanism with evidence-gated drawdowns and mandatory reserve funds.
- A platform where contributors know their ceiling, floor, drawdown criteria, and reserve position before they commit a single dollar.
- A direct contractual relationship between the contributor and the project — Mine Contribo is the platform and oversight framework, not the fund manager.
What Mine Contribo is not
- Not a collective investment scheme — we do not pool money into a general fund managed on your behalf.
- Not a lending facility — contributors do not receive interest. They receive a share of actual project revenues.
- Not a guaranteed return product — the return pool reflects actual project performance within the declared term.
- Not an equity transfer — contributors hold no ownership stake in the project company.
