First Quantum & Tertiary Minerals Expand Gold‑Copper‑Silver & Silver‑Oxide Resources in Finland and Zambia

Corporate Update on Exploration Initiatives in Finland and Zambia

First Quantum Minerals Ltd (FQM) and Tertiary Minerals plc have recently disclosed significant drilling programmes aimed at expanding their resource bases in distinct mineral markets. Both companies are advancing exploration efforts that could materially enhance their asset portfolios, with FQM focusing on the extension of a gold‑copper‑silver deposit in Finland, and Tertiary Minerals targeting a high‑grade silver‑oxide body in Zambia. The following analysis contextualises these developments within broader industry dynamics and economic trends.

First Quantum Minerals Ltd – Angesneva Deposit, Finland

FQM’s Kiimala Trend project, located in the northern sector of Finland, has entered a new phase of exploration. The company has drilled two diamond‑core holes totaling 459 metres to evaluate infill and strike extensions of the existing gold‑copper‑silver resource. The results are encouraging:

• Mineralisation beyond current boundaries: Significant mineralised zones were confirmed outside the existing resource envelope, particularly to the north.
• Higher than expected by‑product grades: Copper and silver grades may be elevated relative to earlier estimates.
• Planned re‑analysis of historical core: FQM intends to re‑assay existing core samples to incorporate these by‑product metals into future resource models.
• JORC‑2012 compliance: An updated resource estimate will be released later in 2026, adhering to JORC guidelines.

A subsequent drilling programme is scheduled for the second half of the year, which will further delineate the deposit’s extent and grade distribution. This incremental approach exemplifies a disciplined exploration strategy, prioritising data integrity and regulatory compliance before committing to larger capital outlays.

Tertiary Minerals plc – Mushima North Project, Zambia

Tertiary Minerals has announced a comprehensive drilling initiative at its Mushima North project. The programme will involve approximately 4,000 metres of reverse‑circulation (RC) drilling with the following objectives:

• Target A1 development: The primary focus is on establishing a robust mineral‑resource estimate under JORC guidelines.
• Oxide zone infill: Drilling will prioritise the oxide layer, which typically hosts high‑grade silver‑oxide deposits.
• Extension testing and adjacent target exploration: Additional drilling will probe the potential for lateral expansion and explore nearby mineralised zones.
• Technical cooperation with First Quantum Minerals: FQM’s partnership provides Tertiary access to historical exploration data and regional expertise, enhancing the project’s technical robustness.

Mushima North is positioned within Zambia’s Copperbelt, an area that has attracted sustained investment due to its rich copper‑silver resources. The focus on silver‑oxide, a commodity with growing demand in battery technology and electronic components, aligns with broader market trends favouring high‑grade, environmentally compliant mineral streams.

Cross‑Sector Analysis and Economic Context

Both FQM and Tertiary Minerals operate within the broader resource extraction sector but target different commodity combinations—gold‑copper‑silver versus silver‑oxide. Key observations include:

The diversification of commodity focus reflects a strategic hedging of commodity price risk. Gold and copper serve as traditional safe‑haven and industrial metals, respectively, while silver’s dual role as a precious metal and a key component in electronic and renewable energy technologies enhances its long‑term value proposition.

From a macroeconomic standpoint, both projects are situated in regions that offer distinct geopolitical and regulatory environments:

• Finland provides a stable political climate, transparent regulatory processes, and a robust infrastructure network, reducing operational risks for exploration and subsequent development.
• Zambia offers abundant mineral resources but faces challenges such as fluctuating exchange rates, taxation, and a need for sustainable mining practices. However, the country’s active mining policy and interest in foreign investment mitigate these risks.

The exploration activities also align with broader trends in resource economics:

• Sustainability and ESG considerations: Both companies are likely to emphasize environmental stewardship and community engagement, given increasing investor scrutiny and regulatory pressure.
• Technological advancement: The use of diamond core drilling and RC techniques represents industry best practices, enhancing data quality and reducing exploration costs.
• Commodity price cycles: The timing of these programmes coincides with rising metal prices, suggesting a favourable environment for resource expansion.

Outlook and Next Updates

Both First Quantum Minerals and Tertiary Minerals are poised to deliver critical updates in the coming months. Anticipated disclosures include:

• Resource revisions: Updated JORC‑compliant resource estimates incorporating new drilling data and re‑assayed core samples.
• Economic assessments: Feasibility studies or preliminary economic evaluations to gauge project viability.
• Stakeholder engagement: Updates on permitting, community relations, and ESG compliance.

For market participants, monitoring the progress of these drilling programmes will provide insights into the companies’ growth trajectories, commodity exposure, and risk profiles. The systematic approach to exploration—rigorous data collection, compliance with international reporting standards, and strategic partnerships—underscores a prudent path toward expanding mineral assets while managing inherent sectorial risks.
