Group Eleven’s Ballywire Zinc Silver Copper Discovery Expands in 2026

When Geology Meets Strategy: Why Ireland's Emerging Polymetallic District Is Attracting Serious Attention

Base metals exploration in Europe has long been overshadowed by headline-grabbing discoveries in Latin America, Africa, and the Asia-Pacific. Yet some of the world's most geometrically predictable and metallurgically cooperative ore systems sit beneath the green limestone country of western Ireland, quietly waiting for the right combination of capital, technology, and geological understanding to unlock them. The Group Eleven Ballywire zinc silver copper discovery is rapidly emerging as the most consequential demonstration of that potential in over a decade.

What makes Ballywire particularly instructive is not just the grade or the scale, though both are compelling. It is the way the deposit's architecture challenges conventional thinking about how polymetallic systems should be classified, valued, and explored. A project that began as a zinc story is now being reconsidered as a silver story, a copper story, and increasingly, a critical minerals story, all at once.

From a Single Intercept to a 3.2-Kilometre System

In September 2022, Group Eleven Resources drilled its first mineralised hole at the Ballywire prospect within the company's 100%-owned PG West project in Ireland's Limerick Basin. The target was a stratigraphically confined zinc-lead-silver horizon hosted within Waulsortian Limestone, a geological sequence well known to Irish exploration geologists as the dominant host for the country's historically significant carbonate-hosted zinc deposits.

What followed over the next 18 months was a systematic expansion programme that transformed a single intercept into one of the most discussed exploration discoveries in the European mining sector. By early 2026, the company had completed 77 drill holes totalling approximately 30,000 metres. The April 2026 extension drill hole, designated 25-3552-52, pushed confirmed mineralised strike length to 3.2 kilometres, adding a further 600 metres to the previously defined 2.6-kilometre extent.

The expansion trajectory tells its own story:

Critically, the 3.2-kilometre confirmed zone sits within a 6-kilometre prospective trend defined by four gravity anomalies designated A, B, C, and D. Gravity surveys are a standard geophysical tool for base metals exploration precisely because sulfide-rich ore zones generate measurable density contrasts relative to barren limestone host rock. The primary discovery and all systematic drilling to date has focused on Anomaly C, while Anomaly B contains historical mineralisation from a prior operator's 1997 drilling campaign. Anomalies A and D remain largely untested, representing the most significant blue-sky potential in the district.

The Two-Horizon Architecture That Changes the Conversation

Perhaps the most consequential geological revelation at Ballywire has been the identification of a second, deeper mineralisation system operating beneath the primary zinc-lead-silver blanket. Two vertically separated systems now define the deposit:

• Upper horizon: A flat-lying, stratabound zinc-lead-silver blanket controlled by the Waulsortian Limestone stratigraphy
• Lower horizon: Sub-vertical copper-silver shoots located approximately 100 to 200 metres beneath the zinc zone, fault-controlled along south-dipping structural corridors

The genetic relationship between these two systems reflects a coherent hydrothermal model. Mineralised fluids ascending through fault structures approximately 350 million years ago deposited copper and silver in fault-parallel zones before encountering the base of a reactive carbonate absorption horizon, where zinc and lead precipitated laterally as a flat-lying blanket. The two systems are, in this model, products of the same hydrothermal plumbing network, separated in space by the contrasting physicochemical environments that governed deposition.

This architecture is not merely theoretically interesting. Furthermore, it has practical implications for how the deposit's economics should be modelled and how investors should frame their expectations.

What the Drill Results Reveal About Grade, Thickness, and Metal Distribution

The intercepts returned from Ballywire span a wide range of thicknesses and grades, reflecting the natural variability of a large, evolving hydrothermal system. Interpreting drill results carefully is essential for any serious assessment of the project's economics.

Zinc-Lead-Silver Horizon: Upper System

The upper zinc-lead-silver blanket has produced some remarkably thick, high-grade intersections. World-average zinc ore grades at operating mines typically range between 4% and 8% Zn, which makes the following intercepts particularly notable:

• 57.3 m at 6.22% Zn+Pb, including 23.5 m at 12.32% Zn+Pb
• 47.1 m at 3.1% Zn, 1.4% Pb, and 22 g/t Ag, including 12.9 m at 7.7% Zn, 3.2% Pb, and 151 g/t Ag
• Prior best intercept: 29.6 m at 10.6% Zn+Pb, 78 g/t Ag, and 0.15% Cu
• April 2026 extension: 22 m of zinc-lead-silver mineralisation confirming 3.2 km strike

The thickest intercepts exceeding 50 metres of true width with combined Zn+Pb grades above 10% are exceptional by any global benchmark. Importantly, true width variability — ranging from as little as 3 metres to over 50 metres across the system — remains the primary uncertainty for tonnage estimation and will require systematic infill drilling at approximately 100-metre spacing to resolve.

Copper-Silver Feeder System: Lower Horizon

The discovery of high-grade copper-silver shoots in the lower horizon fundamentally reframes how Ballywire should be classified. The May 2025 assays from hole 25-3552-31 returned results that would be considered exceptional in any copper-silver exploration context globally:

For context, world-average copper ore grades at operating mines range from approximately 0.5% to 1.5% Cu, placing Ballywire's copper intercepts firmly in the upper tier of commercial viability. The silver grades associated with the copper zone are extraordinary, with the broader geological literature on silver mining suggesting that byproduct silver credits of 60 to 90 g/t are typical in base metals settings. Ballywire's 356 to 838 g/t Ag in the copper horizon positions silver as a genuine co-product rather than a trace credit.

Silver Grade Distribution Across Both Systems

The silver grade distribution at Ballywire is not uniformly bonanza-grade. The system contains a reliable background of 50 to 150 g/t throughout the zinc horizon, punctuated by exceptional copper-associated silver values that suggest a high-temperature, fault-proximal enrichment process in the lower system.

Silver as the Primary Revenue Driver: Rethinking the Metal Economics

One of the most counterintuitive aspects of the Group Eleven Ballywire zinc silver copper discovery is that zinc, despite providing the volumetric foundation of the deposit, is not necessarily the dominant revenue contributor. At silver prices above approximately US$50 per ounce, gross metal value modelling places silver ahead of zinc as the primary per-tonne revenue driver, even accounting for zinc's superior tonnage contribution.

This has meaningful implications for how the project is positioned in capital markets. Consider the three distinct investor audiences the deposit's metal mix can address:

1. Base metals investors attracted by the volumetric zinc-lead tonnage and the operational familiarity of Irish-type stratabound systems
2. Precious metals and silver-focused funds drawn by extraordinary silver grades and the deposit's gross metal value profile
3. Critical minerals and energy transition capital engaged by the copper and germanium content and the associated EU regulatory framework

For silver-focused mining companies whose portfolios are concentrated in Latin American jurisdictions, Ballywire represents a structurally rare opportunity: high-grade silver in a politically stable, EU-member-state jurisdiction with established mining infrastructure and regulatory predictability. Ireland's mining history, combined with its EU membership, provides a risk-adjusted alternative to jurisdictions where permitting timelines and social licence challenges are elevated.

The copper content introduces a fourth dynamic. Copper pricing operates on a different cycle to silver and zinc, responding primarily to grid infrastructure investment, electric vehicle adoption rates, and industrial activity in major manufacturing economies. Having copper as a third independent revenue stream reduces overall metal price sensitivity and broadens the deposit's appeal to investors with energy transition mandates.

Understanding the 24X Expansion Framework

The theoretical expansion multiplier that management has outlined for Ballywire requires careful interpretation. The 24X framework is constructed from three independent geological vectors, each representing a multiplication of prospective mineralised volume:

1. Four gravity anomalies (A, B, C, D) defining the full 6-kilometre prospective trend, of which only Anomaly C has been systematically drilled
2. Three parallel mineralised trends running north, central, and south of the main discovery corridor, of which only the central trend is currently confirmed over 3.2 kilometres
3. Two vertically separated mineralised horizons: the upper zinc-lead-silver blanket and the lower copper-silver feeder system

The arithmetic produces a 4 × 3 × 2 = 24X theoretical multiplier relative to currently drill-defined mineralisation. Management has been explicit that this is a conceptual exploration framework representing the maximum geological opportunity space, not a resource estimate, production forecast, or commitment that all vectors will materialise.

The 24X multiplier is best understood as a map of unknowns rather than a promise of outcomes. Its value to investors lies in defining where the drill programme should be directed, not in pre-empting what will be found.

With approximately 25% of the 6-kilometre trend systematically tested across 77 holes totalling ~30,000 metres, the programme is still in a phase where each new result can meaningfully change the district-scale picture.

The $18 Million Funded Programme: What It Enables and When

The capital structure underpinning the next phase of exploration at Ballywire was substantially reinforced in early 2026. A bought deal financing that closed on March 11, 2026 raised $12 million, complementing an earlier $5.75 million raise to bring total available treasury to approximately $18 million as of the end of March 2026.

This capital enables an expansion from the approximately 20,000 metres of historical programme drilling to between 67,000 and 75,000 metres of forward drilling over approximately two years, without requiring additional capital raises. Three drill rigs are currently active on site, with programme priorities structured as follows:

• Strike extension testing across all four gravity anomalies (A, B, C, D)
• Step-out drilling to test northern and southern parallel trends
• Infill drilling at 100-metre spacing to support a maiden Mineral Resource Estimate
• Deeper targeting to define the copper-silver feeder system extent along the full 3.2-kilometre strike

Management targets a maiden Mineral Resource Estimate (MRE) within 12 to 18 months, supported by third-party 3D geological modelling to resolve thickness variability. The stratigraphically consistent, flat-lying nature of the primary zinc horizon is expected to make resource modelling more efficient than structurally complex deposit types such as skarns or sheared VMS systems, where mineralisation can be poddy and geometrically unpredictable.

Irish-Type Geology vs. VMS: Why the Deposit Architecture Matters for Economics

The classification of Ballywire as an Irish-type carbonate-hosted deposit rather than a VMS (Volcanogenic Massive Sulfide) system carries significant practical implications that are often underappreciated by investors who are less familiar with deposit geology.

The sulfide mineralogy at Ballywire — primarily chalcopyrite with tennantite-tetrahedrite in the copper zones alongside sphalerite and galena in the zinc horizon — is non-oxidised. This is an important distinction. Sulphide ores respond predictably to conventional flotation processing, with well-documented recovery benchmarks available from global analogues. Oxidised copper ores, by contrast, require hydrometallurgical processing routes that are considerably more complex and capital-intensive.

The presence of trace germanium and antimony adds further dimensions to the mineralogical picture. Germanium is known to substitute into sphalerite in some Irish-type deposits, and its detection at Ballywire opens a potential byproduct credit stream with meaningful strategic implications. Furthermore, antimony's strategic role in defence and semiconductor industries adds yet another layer of critical minerals relevance to the deposit's profile.

EU Critical Raw Materials Act: Strategic Context Without Overstating Project-Specific Benefits

The European Union's Critical Raw Materials Act represents a regulatory framework designed to reduce European dependence on imported critical minerals. Under this framework, copper and germanium are both designated EU critical raw materials, recognised as essential inputs for electrification infrastructure, semiconductor manufacturing, defence applications, and fibre optic communications.

Zinc is not currently designated as a Critical Raw Material under the EU CRM Act. This distinction matters because it means the project's potential qualification for streamlined permitting provisions rests specifically on demonstrating sufficient copper and germanium resource definition, not on the zinc endowment that defines the deposit's primary tonnage base.

It is important to note that EU CRM Act provisions and fast-track permitting pathways are regulatory frameworks available to qualifying projects under defined criteria. Whether Ballywire ultimately qualifies for any such provisions depends on future resource definition work and regulatory assessment processes that have not yet been completed. Nothing in publicly available disclosures confirms that fast-track status has been granted or formally applied for.

Ireland's position as an EU member state ensures the CRM Act's provisions apply directly, without the export-dependency dynamics that affect non-EU producing jurisdictions. The following comparison illustrates why jurisdictional positioning matters to capital allocation decisions:

Strategic Shareholders and What Their Presence Signals

The ownership structure of Group Eleven Resources provides context that the market does not always price efficiently in early-stage exploration companies. Two significant shareholders stand out:

• Glencore: Holds a 16.1% equity position in Group Eleven. Glencore is the world's largest zinc producer and trader, and its Pallas Green deposit sits in the same Limerick Basin district as Ballywire. A substantial equity stake from the world's dominant zinc trading house represents informed strategic interest that goes beyond passive portfolio allocation.

• Michael Gentile: Holds approximately 16% of the company. Gentile is a well-regarded Canadian resource sector investor with a track record of backing early-stage exploration companies.

Glencore's proximity through Pallas Green is particularly noteworthy from an optionality perspective. Existing district infrastructure could theoretically reduce future capital requirements for Ballywire's development, though any such scenarios remain entirely speculative at this stage and no formal commercial relationship between the two parties has been publicly confirmed.

Key Risks Investors Must Understand

No assessment of the Group Eleven Ballywire zinc silver copper discovery would be responsible without an honest accounting of the material risks that accompany an exploration-stage project of this nature.

This section does not constitute financial advice. Exploration-stage companies carry significant uncertainty, and past drill results are not indicative of future resource estimates or development outcomes.

Technical risks include:

• True thickness variability from 3 m to 50+ m remains the central uncertainty for tonnage modelling
• Northern and southern parallel trends are geologically inferred but not yet drill-confirmed
• Not all four gravity anomalies are guaranteed to host economic mineralisation
• Third-party 3D modelling required before a maiden MRE can be published

Development and timeline risks include:

• Standard development timelines from exploration to production in similar settings have historically ranged from 10 to 15 years
• EU CRM fast-track provisions are not guaranteed and require demonstrated resource sufficiency in qualifying metals
• Metallurgical test work on the copper-silver ore stream remains in early stages

Capital and market risks include:

• The $18M treasury funds the current two-year programme, but post-programme capital requirements remain undefined
• Exploration-stage companies carry binary drill result risk where any individual hole may not meet expectations
• Silver price volatility directly and materially impacts gross metal value calculations given silver's dominant revenue contribution

The 24X multiplier, the silver-dominant economics, and the EU critical minerals narrative are all compelling analytical frameworks. However, none of them change the fundamental reality that Ballywire is a pre-resource, exploration-stage discovery. The distance between a compelling drill hole and a producing mine is long, expensive, and uncertain.
