Sego Resources' Breakthrough Copper Porphyry Discovery at the Miner Mountain Project: Strategic Growth Potential in a Geopolitically Favorable Jurisdiction

Sego Resources Inc. (TSX-V: SGZ) has made a transformative discovery at its Miner Mountain Project in British Columbia, unearthing a copper porphyry within the South Gold Zone in December 2025 according to a press release. This development, coupled with the project's existing gold-centric preliminary economic assessment (PEA) and favorable jurisdictional conditions, positions Sego as a compelling candidate for investors seeking exposure to resource expansion and geopolitical stability in the mining sector.

A Dual-Commodity Catalyst: Copper Porphyry and Gold Synergy

The December 2025 discovery marks the first confirmed copper porphyry at Miner Mountain, with mineralization hosted in potassic altered microdiorite and monzodiorite, featuring chalcopyrite concentrated in potassium feldspar alteration zones. While the South Gold Zone has historically been a focus for near-surface gold, the identification of a deep-seated copper-gold porphyry system-particularly in DDH25-69, which exhibited the most extensive mineralization-signals a significant shift in the project's resource profile.

This dual-commodity potential is critical. Copper, a cornerstone of the global energy transition, is experiencing heightened demand for electric vehicles, renewable infrastructure, and grid modernization. Sego's ability to leverage existing gold infrastructure to explore for copper porphyry-while maintaining a gold-centric PEA-creates a layered value proposition. The company's July 2025 PEA already projected robust economics, including a $2.3 billion after-tax NPV and 32% IRR, but the addition of copper could amplify these figures through diversified revenue streams and reduced commodity risk.

Geopolitical Advantages: Stability, Infrastructure, and Indigenous Collaboration

The Miner Mountain Project's location near Princeton, British Columbia, offers a strategic edge. The region is home to the operating Copper Mountain Mine, providing access to established infrastructure, including roads, power, and processing facilities.

Moreover, Sego has cultivated a collaborative relationship with the Upper Similkameen Indian Band through a Memorandum of Understanding, a critical factor in modern mining projects, where community engagement and environmental stewardship are paramount. The company's prior recognition for environmental reclamation efforts further underscores its alignment with ESG (Environmental, Social, and Governance) standards, a growing priority for institutional investors.

British Columbia's mining-friendly regulatory environment adds another layer of appeal. Unlike jurisdictions plagued by political uncertainty, the province offers a predictable legal framework and a skilled labor pool, reducing operational risks for Sego.

Economic Viability and Future Exploration Roadmap

The July 2025 PEA, while predicated on gold-centric assumptions, already demonstrates strong economic resilience. At $3,300/oz gold and $36/oz silver prices, the project's 24.5-year mine life is projected to yield 122,000 ounces of gold annually, with 89.3% recovery rates via a leaching and gravity process. Initial capex of $1.25 billion is offset by sustaining capital and closure costs funded through operating cash flows.

The December 2025 copper porphyry discovery, though not yet integrated into the PEA, could catalyze a revised economic model. Sego's drilling program-focused on confirming continuity in the South Gold Zone and deepening exploration in the Cuba Zone- aims to elevate resources to NI 43-101 standards. A Pre-Feasibility Study (PEA) update, slated for H1 2025, will incorporate 2024 drill data but may exclude the latest December 2025 findings. However, ongoing drilling including a 1,000-meter program in December 2025 suggests the company is actively positioning the project for a future PEA revision that could include copper porphyry metrics.

Strategic Implications for Investors

Sego's dual-commodity strategy, combined with its jurisdictional advantages, creates a compelling narrative for long-term growth. The company's exploration of a non-cyanide-based leaching process-achieving 95% gold recovery in 2021-further enhances its environmental credentials and operational efficiency.

For investors, the key risks include the timing of PEA updates and the technical challenges of expanding resource estimates. However, the December 2025 discovery has already triggered a 1,000-meter drilling program, to assess porphyry continuity, indicating management's confidence in the asset's potential. If the PEA revision incorporates copper porphyry data, the project's NPV and IRR could see upward revisions, potentially attracting larger capital partners or accelerating a build decision by 2027.

Conclusion

Sego Resources' Miner Mountain Project exemplifies the intersection of geological promise, geopolitical stability, and strategic foresight. The December 2025 copper porphyry discovery not only expands the project's resource base but also aligns with global demand trends for critical minerals. With a favorable jurisdiction, existing infrastructure, and a management team prioritizing ESG and community collaboration, Sego is well-positioned to transform Miner Mountain into a multi-commodity asset with long-term value. Investors seeking exposure to a scalable, low-risk exploration story in a geopolitically secure region should closely monitor the company's upcoming PEA update and drilling results.
