G2 Goldfields' Maiden PEA for High-Grade Oko Project Forecasts 281,000 Ounces Annual Production at $1,137 AISC

G2 Goldfields Unveils Strong Economics for Oko Gold Project

G2 Goldfields Inc. delivered its maiden Preliminary Economic Assessment (PEA) for the high-grade Oko Gold Project, revealing that the operation has the potential to generate significant annual production at a highly competitive average all-in sustaining cost (AISC) of just US$1,137 per ounce of gold. The assessment, published in late 2025, positions the project for industry-leading margins, driven by its high-grade resource base.

The PEA provides a comprehensive financial and technical outlook for the project, which is hosted in a region described as mining-friendly. The results indicate that the Oko Project is capable of sustaining a long life of mine (LOM) operation, combining both underground and open pit mining methods.

Projected Production and Cost Efficiency

The core economic projections highlight the project's ability to deliver substantial output over more than a decade. Key financial metrics from the PEA include:

• Life of Mine (LOM): A projected 14-year operational lifespan.
• Average Annual Production: 281,000 ounces of gold, sustained across years 2 through 11 of the operation.
• All-in Sustaining Cost (AISC): An average of US$1,137 per ounce of gold, positioning the project favorably against global industry averages.

The company noted that the combination of high-grade material and efficient operations is expected to translate into very significant annual production and strong margins.

Updated High-Grade Mineral Resource Estimate

The robust economics outlined in the PEA are underpinned by G2 Goldfields’ updated Mineral Resource Estimate, which incorporated six months of new drilling data. The updated resource base confirms the high-grade nature of the deposit:

• Indicated Mineral Resource: 1.6 million ounces (Moz) of gold at an average grade of 3.24 grams per tonne (g/t Au).
• Inferred Mineral Resource: 1.9 Moz of gold at an average grade of 3.31 g/t Au.

The substantial resource base, totaling 3.5 Moz across both categories, provides the foundation for the 14-year LOM plan. The high grades are a crucial factor enabling the low AISC forecast, which is essential for maintaining profitability even during periods of commodity price volatility.

Forward Outlook and Materiality

The maiden PEA serves as a critical milestone for the Oko Gold Project, moving it closer to development decisions. The data demonstrates that the project has the potential to be a significant, long-term gold producer. The focus on high-grade material and the resulting low cost structure suggests that G2 Goldfields is well-positioned to capture substantial value once the project moves into the production phase, expected to ramp up significantly starting in the second year of operations.
