Above-Ground Gold creates an unusual alignment between investment objectives and environmental outcomes. Recovering gold from legacy tailings does not simply extract value — it progressively removes a historic environmental liability.
Conventional mining creates new environmental disturbance in pursuit of geological value. New land is disturbed. New voids are created. New surface deposits are generated. The environmental cost of production is a real and ongoing consideration for investors, regulators and communities alike.
Above-Ground Gold operates from a fundamentally different starting point. The environmental disturbance has already occurred. The tailings deposits already exist. The land is already affected. The question is not whether disturbance will happen — it is whether the material can be processed commercially, removing it from its current state and progressively rehabilitating the affected area.
When Synterra processes a legacy tailings deposit, it simultaneously recovers gold and removes historic environmental liabilities. This alignment between investment returns and environmental outcomes is one of the most distinctive features of the Above-Ground Gold model.
Tailings retreatment represents one of the clearest applications of circular economy principles in the mining sector. Material that was treated as waste by previous generations of miners is reconceived as a resource — extracted, processed and monetised, while simultaneously reducing the historic environmental footprint.
Synterra's Above-Ground Gold projects do not require new underground development, new open-pit excavation or disturbance of land that has not already been affected by historic mining activity. Operations are confined to the existing tailings footprint.
As tailings material is reclaimed and processed, the historic deposit is progressively reduced. Processed material is managed in accordance with modern environmental standards, and affected land is rehabilitated progressively through the project life.
In a fully retreated tailings project, the original deposit footprint is eventually cleared. The environmental closure obligation — previously an open-ended liability for former mine owners, the State or affected communities — is progressively discharged as the project advances.
Many historic gold tailings deposits generate acid mine drainage, which poses persistent risks to groundwater, surface water and surrounding ecosystems. Retreatment that progressively removes the source material reduces this risk over time, providing a direct environmental benefit to surrounding communities.
Tailings processing is water-intensive. Synterra's project designs incorporate closed-loop water management and recycling systems where practicable, and our technical team ensures that water use licensing and environmental management plans are integrated into project development from the earliest stage.
A successfully retreated tailings deposit leaves rehabilitated land — potentially available for agricultural, community or commercial reuse — where a derelict historic tailings dump previously occupied the landscape. This is a meaningful long-term contribution to affected communities.
Gold tailings retreatment projects create direct employment — in plant operations, maintenance, laboratory analysis, administration and security — as well as indirect employment through local procurement of goods and services. Synterra's project development process explicitly considers local employment and procurement opportunities from the earliest feasibility stage.
Many of Southern Africa's legacy tailings deposits are located in communities with deep historic connections to the mining industry. These communities often bear residual environmental impacts from the tailings themselves — dust, drainage, contamination — that retreatment operations can materially reduce over the project life.
Synterra's approach to community engagement is based upon early, transparent communication about the nature of proposed operations, the environmental management approach and the expected local economic contributions. We recognise that community support is a prerequisite for operational success, particularly in the Southern African regulatory environment.
In South Africa, mining operations are subject to a mandatory Social and Labour Plan process. Synterra integrates SLP development into its project structuring from the pre-feasibility stage, ensuring that social commitments are commercially realistic and appropriately funded through the project finance structure.
Synterra's governance model is built around independent verification, transparent reporting and commercially rigorous accountability structures. These principles apply to technical claims, environmental management and investor reporting alike.
Every resource claim Synterra advances towards investment is subject to independent technical verification by qualified competent persons under recognised international reporting standards — NI 43-101, JORC or SAMREC as appropriate. Synterra does not advance development capital on the basis of unverified internal estimates.
Each project operates under a formal Environmental Management Plan prepared by qualified environmental practitioners and approved by the relevant regulatory authority. EMPs are updated as project development progresses and are a condition of continued operations.
Synterra's investor reporting distinguishes clearly between internally estimated figures used for planning purposes and independently verified resource statements. Illustrative economic projections are presented as scenarios, not forecasts, and are accompanied by explicit disclosure of the assumptions underlying them.
Synterra designs each project around full compliance with the applicable regulatory framework — including mining permits, environmental authorisations, water use licences, social and labour plans and BEE requirements in South Africa, and the equivalent Zimbabwean regulatory requirements. Regulatory risk is assessed and managed as a core element of the investment case.
Synterra's final investment step — Rehabilitate — is not an afterthought. It is the concluding chapter of a complete Above-Ground Gold project cycle: Acquire. Verify. Recover. Rehabilitate.
Rehabilitation planning begins at the project assessment stage. Financial provision for progressive and final rehabilitation is incorporated into the project's financial model and finance structure from the outset. Where regulatory requirements specify rehabilitation bonds or financial guarantees, these are treated as a cost of doing business, not an impediment to project advancement.
The goal at the end of every Above-Ground Gold project is simple: leave the land in better condition than we found it. Remove the historic dump. Manage the processed material responsibly. Restore vegetation where practicable. Hand back land that communities can use.
