Toroparu’s Copper: Show Guyana the Full Accounts

 Toroparu’s Copper: Show Guyana the Full Accounts

OPINION BY : Hem Kumar November 2026

The latest report on Toroparu places an estimated US$1.5 billion in copper beside a projected US$23.4 million royalty payment. The contrast is arresting. It raises a legitimate question about the reported 1.5% copper royalty. But it does not, by itself, establish Guyana’s total return from the copper, much less from the entire project.

The arithmetic deserves scrutiny. So does the agreement behind it.

The central issue is accountability: can the government demonstrate, with public documents and independently tested figures, that the Toroparu bargain adequately compensates Guyana for the extraction of its resources?

Get the numbers right—and then demand answers

Aris Mining’s October 2025 preliminary economic assessment outlines a proposed 21.3-year operation producing approximately five million ounces of gold, 4.9 million ounces of silver and 260 million pounds of copper. Initial construction capital is estimated at US$820 million. These are substantial figures, describing a project with consequences extending well beyond a single administration or election cycle.

At US$6 per pound, the projected copper production would carry an illustrative gross value of US$1.56 billion. Apply a 1.5% royalty to that amount and the result is US$23.4 million.

That calculation is straightforward. What it represents requires greater care.

It is not a complete statement of Guyana’s fiscal benefit. Aris’s published base-case model projects approximately US$1.193 billion in royalties and US$2.174 billion in income taxes across the whole project—roughly US$3.37 billion over its proposed life. Those figures use the assessment’s assumptions, including a US$3,000-per-ounce gold price; they are projections, not money already secured for the Treasury.

Indeed, Kaieteur News previously reported the approximately US$3.4 billion government-revenue projection in November 2025. That earlier account must be reconciled with any suggestion that Guyana’s return can be reduced to the copper royalty alone.

Precision is not a concession to the company. It is what makes criticism harder to dismiss.

Nor should the gross value of copper be presented as company profit. Mining, processing, transportation, capital investment, taxation and closure obligations all affect the economic result. Aris’s own model distinguishes gross revenues from costs, taxes and project cash flow.

An editorial serious about defending Guyana’s interests must make those distinctions—and then ask the harder question: after the relevant costs and risks are accounted for, is the country receiving an adequate share of the economic benefit?

Why just 1.5% for copper?

Reported fiscal terms provide for an 8% gold royalty above the specified price threshold, alongside royalties of 1.5% on copper and silver. A 30% corporate income-tax rate is also reported. These terms require verification against the executed agreement and any amendments, but the disparity between the reported gold and copper royalty rates already warrants an explanation.

Why was 1.5% considered appropriate for copper? What economic assessment supported that decision? Does the government still consider it appropriate for the project now being proposed?

Aris says its revised processing design includes copper flotation from the outset and that copper provides a valuable by-product contribution to revenue. Copper is therefore part of the project’s commercial proposition, not an irrelevant mineral accidentally accompanying the gold.

Calling it a by-product explains its place in the operation. It does not explain why Guyana should accept a 1.5% royalty.

Copper’s growing strategic importance strengthens the case for scrutiny, though it does not guarantee permanently rising prices. S&P Global’s January 2026 study projects demand increasing from approximately 28 million tonnes in 2025 to 42 million tonnes in 2040, driven by electrification, conventional economic demand, artificial intelligence and data centers, and defense.

The government should explain how it assesses that changing commercial context—not merely repeat the terms negotiated years ago.

Publish the bargain, not just its sales pitch

The available documentary record identifies a mineral agreement between ETK and the Government of Guyana dated November 9, 2011. The public deserves access to that agreement, its amendments and the schedules governing the project’s fiscal treatment.

The date alone does not prove that the agreement is defective. Nor does the passage of time automatically establish a legal right to rewrite it. But neither should the agreement’s age become an excuse to avoid explaining its present consequences.

If fiscal-stability provisions restrict changes, publish them.

If import or fuel exemptions are being granted, identify them, explain their purpose and disclose their estimated value. If the government believes the combined royalty-and-tax package is competitive and fair, release the analysis supporting that conclusion.

The same standard must apply to the company’s projected US$3.37 billion in government receipts. That is an important figure, but it is not a certificate of fairness. It is a modelled outcome dependent on assumptions about production, prices, expenditure and taxation.

The public needs to know how that outcome changes when the assumptions change. What happens if construction costs rise? If production falls? If prices remain elevated? What deductions postpone taxable income, and for how long?

A large projected payment does not answer whether the State negotiated well. It tells us that the project is large.

A royalty is only as credible as its enforcement

The terms on paper are only the beginning of the inquiry.

For a project proposing to produce copper concentrates, the authorities should explain how shipments will be independently weighed, sampled, assayed and valued. Aris’s proposed production includes both doré and copper concentrates, making the verification of different saleable products a practical oversight question.

Who verifies the metal content? How are commercial deductions checked? Can Guyana reconcile production records with exports and sales? Will the regulator and revenue authorities have the expertise, access and resources to challenge discrepancies?

These questions are not allegations of wrongdoing. They are the minimum questions a resource-owning country should answer before relying on decades of projected receipts. The same discipline must govern closure and rehabilitation. The public should know what financial security will be required, when it must be funded, who independently assesses its adequacy and who bears any shortfall.

An undertaking to repair a mine site is not the same as money secured to do the work.

Investment must withstand scrutiny

Toroparu remains a development project. Its preliminary economic assessment is not a guarantee of production or profitability, and Aris cautions that mineral resources are not mineral reserves and that its preliminary projections may not be realised. Its project page identifies a prefeasibility study in progress.

Those uncertainties are real. So is the State’s obligation to protect the national interest before the project advances further.

Guyana need not reject foreign investment to insist on better disclosure. It need not pretend mining is costless to question a royalty. And it need not accept incomplete arithmetic to recognize that the government owes citizens a full explanation.

The proper demand is neither blind endorsement nor automatic condemnation. It is publication of the agreement, independent assessment of the fiscal package, disclosure of concessions and enforceable arrangements for taxation, environmental protection and national benefit.

A government defending Toroparu should be able to show its work.

Show the contract. Explain the copper royalty. Cost the concessions. Demonstrate how production will be verified, taxes collected and rehabilitation funded.

Guyana’s minerals do not become public prosperity merely because a company can extract them profitably. That transformation depends on the quality of the bargain and the strength of the institutions enforcing it.The copper beneath Toroparu is not the only thing that must be brought into the open. So must the deal above it.
