CoTec & Copper Intelligence Form DRC Copper Tailings Joint Venture

The Metallurgical Case for Secondary Copper: Why Legacy Tailings Are Attracting Fresh Capital

Across the global mining industry, a quiet but significant reappraisal is underway. For decades, tailings storage facilities were regarded primarily as liabilities: costly to manage, environmentally sensitive, and largely stripped of their economic value. That perception is shifting. As copper supply crunch pressures mount on the back of electrification and grid infrastructure buildout, the economics of reprocessing legacy deposits are increasingly competitive with the capital intensity of developing entirely new mines. Nowhere is this dynamic more pronounced than in the Democratic Republic of Congo.

The Central African Copperbelt represents one of the most mineralogically significant copper-bearing geological formations on the planet. Stretching across the DRC and into Zambia, the belt has been mined continuously for over a century, producing successive generations of tailings that reflect the processing limitations of their era. Early operations relied heavily on gravity separation and basic flotation circuits that left substantial copper values unrecovered.

Later hydrometallurgical and pyrometallurgical techniques improved yields but remained constrained by the reagent selectivity and liberation efficiency available at the time. The cumulative result is a series of tailings deposits whose residual copper content may be commercially significant when evaluated against modern processing benchmarks.

It is within this context that the CoTec Copper Intelligence copper tailings joint venture in the DRC has emerged as a structurally interesting proposition for investors tracking the intersection of processing technology and critical minerals access.

What the Joint Venture Actually Proposes and How It Is Structured

On May 6, 2026, CoTec Holdings Corp. (TSXV: CTH; OTCQB: CTHCF) formalized a non-binding term sheet with U.S.-based Copper Intelligence Inc. (OTC: AFDG, formerly African Discovery Group) to establish an early-stage exploration joint venture targeting historical copper tailings in the DRC. The arrangement also involves investment vehicles connected to CoTec's CEO Julian Treger and Chairman Lucio Genovese, negotiated on an arm's length basis.

Critically, this is not a single-asset transaction. The venture is structured as a platform: a framework for systematically identifying, screening, and evaluating multiple tailings opportunities across the DRC's historic mining districts, with binding commitments made on a per-asset basis only after independent due diligence has been completed.

The structural design addresses a common criticism of early-stage African mining ventures: excessive upfront capital commitment before technical and legal risks are understood. By requiring separate binding agreements for each identified opportunity, the JV avoids blanket exposure to a portfolio of unvalidated assets.

An additional governance layer requires that all resource allocation decisions receive explicit approval from CoTec's independent board members, providing a firewall between insider-affiliated investment vehicles and shareholder capital deployment decisions. Definitive agreements governing the JV's full terms are targeted for completion by Q3 2026, or earlier subject to acquisition progress.

The Technology Differential: Why Tailings Reprocessing Demands a Different Approach

Understanding why CoTec's technology-first model is relevant to DRC tailings requires a brief examination of what makes historical tailings chemically and mineralogically distinct from fresh ore.

When copper ore is processed, the resulting tailings reflect the efficiency ceiling of the technology applied. In older Copperbelt operations, this typically meant:

• Coarser particle size distributions, with some liberated copper particles too fine to be efficiently recovered by flotation circuits of the era
• Elevated oxidation states in residual copper minerals, creating acid-soluble copper fractions that conventional flotation cannot capture
• Mixed mineralogy combining sulphide and oxide copper species, requiring different leaching and recovery chemistry
• Reagent selectivity limitations that left partially-liberated copper associated with gangue minerals

Modern processing approaches, including the copper leaching process used in advanced flotation with selective reagent formulations, sensor-based ore sorting, and tailored hydrometallurgical circuits, are specifically designed to address these characteristics. CoTec's core business model involves applying proprietary processing solutions to assets where conventional operators cannot achieve economic returns, making the mineralogical complexity of DRC tailings directly relevant to its technology proposition.

CoTec CEO Julian Treger has indicated that the company's technologies could offer alternative processing pathways for the historical tailings deposits of the DRC, with validation through metallurgical testwork forming a core component of the due diligence process. This approach embeds technical verification into the commercial framework before capital is committed, reducing the speculative risk that has historically undermined junior mining ventures in the region.

The due diligence phase functions as a real-world proving ground for the technology. Rather than committing capital based on geological estimates alone, the JV structure requires metallurgical confirmation that recovery rates are commercially viable before binding agreements are executed.

The Geopolitical Dimension: U.S. Development Finance and the DRC Copper Supply Chain

The CoTec Copper Intelligence copper tailings joint venture in the DRC sits at the intersection of commercial mining strategy and a broader geopolitical realignment in critical mineral supply chains.

Approximately 90% of the DRC's mineral exports currently flow through Chinese-controlled channels, a concentration that represents roughly 40% of the country's GDP according to the venture's stated context. The DRC mineral wealth and this structural dependency represent both a risk and an opportunity for Western governments seeking to diversify critical mineral access.

The U.S. International Development Finance Corporation (DFC) has already demonstrated active intent to reshape this dynamic. Furthermore, the DFC's involvement in financing the Lobito Corridor rail upgrade — a project designed to expand DRC mineral export capacity from approximately 0.4 million to 4.6 million metric tonnes per year — signals a commitment to building the physical infrastructure necessary for Western mineral access to scale.

The JV has identified DFC financing as a target funding source once sufficient operational scale is established. The key conditions likely include:

1. A defined and independently verified resource base across identified tailings sites
2. Demonstrated processing capability through metallurgical testwork results
3. Clear environmental, social, and governance compliance frameworks
4. Established legal title and tenure security over targeted assets

It is important to note that the JV's stated intention to seek DFC financing reflects an alignment with the DFC's investment priorities, not a confirmation of funding approval or official designation. Investors should assess this as a potential financing pathway that remains subject to the DFC's own eligibility and approval processes. The broader US-Congo minerals partnership context, however, suggests meaningful political will behind this direction.

Navigating the DRC: Regulatory Complexity and Due Diligence Imperatives

The DRC's mining environment presents a set of operational and legal challenges that distinguish it sharply from more established mining jurisdictions. Any credible assessment of the CoTec Copper Intelligence copper tailings joint venture in the DRC must engage with these realities directly.

Tenure risk is among the most material concerns. The DRC's history of colonial-era land tenure, post-independence nationalisation, and successive revisions to its Mining Code have created a landscape where legacy concession rights are frequently contested, ambiguously documented, or administratively complex to transfer. Title verification is not a procedural formality in this context; it is a fundamental prerequisite for any binding commitment.

The due diligence framework embedded in the JV structure addresses this through an asset-by-asset evaluation model. Each identified tailings site must satisfy independent review across five core categories before binding agreements are executed:

Environmental liability carries particular weight in the DRC tailings context. Tailings storage facilities from older operations frequently contain residual reagents, heavy metal concentrations, and acid mine drainage risks that create remediation obligations for new operators. The allocation of historical contamination liability between the JV and former operators must be explicitly resolved in due diligence.

Political and sovereign risk remain ongoing considerations. The DRC has a documented history of regulatory changes affecting foreign mining investors, including royalty rate revisions, windfall tax provisions, and strategic mineral classifications that have altered the economic terms of existing operations. Prudent investors will weigh these risks against the potential returns from secondary copper recovery.

Copper Intelligence's Strategic Value: More Than Operational Experience

Copper Intelligence Inc. is positioned by the JV's architects as the first standalone publicly traded U.S.-listed company focused exclusively on DRC copper operations. This positioning carries practical significance beyond the marketing narrative.

Operating in the DRC requires more than technical competence. Community relations, government engagement, local procurement frameworks, and an understanding of provincial administrative dynamics each contribute materially to whether a project advances or stalls. Copper Intelligence's claimed depth of experience in African operations is presented as a complement to CoTec's processing technology, filling a capability gap that CoTec could not efficiently replicate independently.

For U.S. investors specifically, Copper Intelligence's OTC listing (AFDG) provides accessible exposure to DRC copper through a familiar regulatory framework, potentially broadening the capital base available to the venture as it progresses toward binding agreements. In addition, the copper investment strategies available through such structures are attracting growing attention from capital seeking critical mineral exposure outside traditional greenfield projects.

What Investors Should Understand Before Q3 2026

Is the Venture Ready to Commit Capital?

The CoTec Copper Intelligence copper tailings joint venture in the DRC is, at its current stage, a non-binding term sheet between parties who have committed to a framework rather than a project. This distinction matters enormously for risk assessment.

Several factors will determine whether the venture progresses from framework to operational reality by Q3 2026:

• Whether legal title can be established satisfactorily on identified tailings sites
• Whether metallurgical testwork confirms commercially viable copper recovery rates
• Whether environmental liability can be scoped and allocated without creating unacceptable exposure
• Whether CoTec's independent board approves resource allocation for specific identified opportunities
• Whether definitive agreement negotiations between all parties reach satisfactory terms within the targeted timeframe

How Does the Copper Price Environment Factor In?

The copper price environment provides a supportive backdrop. With benchmark prices testing elevated levels, the economics of secondary copper recovery from legacy tailings are increasingly compelling relative to the capital intensity and timeline of greenfield development.

A new open-pit copper mine in a complex jurisdiction like the DRC typically requires years of feasibility work, environmental permitting, and infrastructure development before first production. A tailings reprocessing operation with established site access, known mineralogy, and existing infrastructure proximity can compress that timeline materially.

This article contains forward-looking analysis regarding a non-binding term sheet. Nothing in this article constitutes financial advice. Investors should conduct independent due diligence and consult qualified financial advisers before making investment decisions. Junior mining ventures, particularly those operating in high-risk jurisdictions, carry material risks including but not limited to regulatory, operational, geological, and geopolitical uncertainties.
