Fully-Funded Maiden Drilling Program to Begin August 2026

Lux Copper announced a fully-funded maiden drilling program scheduled to commence in August 2026, following ongoing drill permitting. This milestone marks the company’s transition from surface exploration to subsurface testing of the identified mineralisation. Drilling will be systematically conducted across multiple targets within the district-scale system, reflecting a disciplined exploration approach aimed at validating the company’s exploration model and building upon the exceptional surface grades already discovered.

By securing full funding prior to drilling, Lux Copper has eliminated a common financial hurdle faced by junior explorers, demonstrating management’s confidence in the project’s prospectivity and providing investors with clear visibility on upcoming exploration activities. The systematic testing of multiple targets is designed to generate several catalysts for value creation in the near term.

Strategic Location in Ambler Mining District Near World-Class Deposits

Lux Copper’s extensive land holdings are strategically situated within the Ambler Mining District, one of North America’s premier copper exploration regions. This district hosts world-class deposits operated by major multinational resource companies and has seen significant merger and acquisition activity recently, underlining its strategic importance for copper and polymetallic minerals. Proximity to established operations offers advantages in infrastructure, regional geological insights, and potential strategic partnerships or consolidation opportunities.

The Ambler Mining District’s tier-1 jurisdiction status is supported by Alaska’s stable regulatory framework, efficient mining permitting processes, and alignment with U.S. critical minerals policies. These factors reduce exploration risk and provide clarity on the pathway to development, distinguishing the region from less developed mining areas.

Copper and Zinc Recognized as Critical Minerals for Energy Transition and Defence

Lux Copper’s focus on copper and zinc aligns with the strategic importance of these metals in global energy transition and defence sectors. Copper is vital for power grid infrastructure, power generation, data centres, energy transmission, and renewable energy technologies such as wind and solar inverters. It is also essential for electric motors, energy storage, telecommunications, and military equipment including vehicle wiring, radar systems, and secure communications.

Zinc complements these roles by enhancing infrastructure durability and protecting energy systems. It is crucial for galvanizing steel, producing brass, and is used in emerging battery technologies like zinc-air and nickel-based systems, as well as sacrificial anodes for corrosion protection. In defence, zinc strengthens military ships, vehicles, and alloys, providing corrosion resistance in harsh environments. The U.S. government’s classification of copper and zinc as critical minerals underscores their importance to national economic and security interests, supporting long-term demand and policy backing for domestic resource development.

Alignment with U.S. Critical Minerals Policy and Energy Transition Trends

Lux Copper’s operations in the United States align with geopolitical trends emphasizing domestic critical mineral development. U.S. policies increasingly aim to reduce reliance on foreign mineral sources vital to defence, energy transition, and high-tech manufacturing. Alaska’s tier-1 status, stable governance, and established mining infrastructure make it a strategic location for such development. Lux Copper stands to benefit from policy support encouraging exploration and development of domestic critical mineral deposits.

The global shift to renewable energy and electric vehicles is expected to drive sustained demand for copper and zinc. Renewable infrastructure, including solar panels, wind turbines, and grid upgrades, requires substantial copper for electrical transmission and power conversion. Electric vehicles demand significantly more copper than traditional vehicles, indicating strong copper demand growth. Zinc demand is projected to rise with increased infrastructure supporting energy transition goals. These long-term trends create a favorable environment for copper and zinc exploration companies.

Extensive Untested Areas Offer Significant Discovery Potential

Lux Copper’s presentation highlights that large portions of its property remain untested despite exceptional surface mineralisation grades. This suggests the company has only begun to uncover the district-scale system’s full potential. The blend of outstanding surface grades, minimal historical drilling, and untested ground forms a strong foundation for discovery-focused exploration aimed at expanding known mineralisation and evaluating new targets. Management plans systematic exploration across multiple targets, reflecting a methodical approach to assessing the property’s full prospectivity.

The district-scale nature of the system implies multiple mineralised zones and targets, each with significant resource potential. Lux Copper’s strategy to systematically test these targets offers multiple opportunities for material discoveries and resource definition over time. For exploration-focused investors, the untested areas and exceptional grades present compelling reasons to follow the company’s progress. Ultimately, success will depend on drilling results and management’s ability to convert surface anomalies into economically viable mineral resources.

IPO Presentation Provides Context for Forward-Looking Investment Opportunity

This update was released as part of Lux Copper’s IPO presentation in July 2026, indicating the company’s transition to public status at that time. The presentation aimed to communicate the investment proposition to prospective public investors, detailing assets, leadership, exploration strategy, and near-term catalysts. The IPO context explains the emphasis on strong investment highlights and upcoming milestones during capital raising.

The fully-funded maiden drilling program is particularly significant in the IPO setting, reassuring investors that the company has secured necessary capital to execute exploration plans.

The outlined near-term catalysts, including drill permitting and the August 2026 drilling start, offer concrete milestones for investors to monitor progress, enhancing the investment appeal during the IPO.

Exploration Risks and Mineral Resource Uncertainties

Investors should recognize that mineral exploration carries inherent technical and financial risks. Exceptional surface grades do not guarantee subsurface mineralisation will be confirmed by drilling or that any discovered mineralisation will meet the size, grade, or continuity standards to qualify as a mineral resource. Drilling outcomes may differ from surface indications, and exploration models may require adjustment based on new data. Interpretation of results involves uncertainty, with varying expert opinions possible.

Alaska’s operational environment presents challenges including harsh weather, remote location, and operational complexity, which may impact exploration execution and costs. Permitting delays or regulatory changes could affect timelines. Commodity price volatility, especially in copper and zinc, may influence the economic viability of any resources defined. Changes in U.S. critical minerals policy or Alaska resource regulations could also impact operations. Exploration is a high-risk activity with no assurance of commercial success, and most projects do not result in economically viable mineral discoveries.
