Godolphin Resources Lewis Ponds Delivers Premium Metallurgical Results

Superior Metallurgical Performance Delivers Investment-Grade Concentrates

Godolphin Resources (ASX: GRL) has delivered exceptional Godolphin Resources Lewis Ponds metallurgical results from its comprehensive testing programme, significantly improving concentrate quality and gold recovery compared to historical performance. The announcement detailed the production of two high-grade concentrates: a clean zinc concentrate grading >64% Zn and a premium lead-gold-silver concentrate delivering >31% Pb, >16.7 g/t Au, and >1,580 g/t Ag.

These results represent a substantial upgrade over 2018 testing, with enhanced gold recovery and improved impurity rejection—particularly reducing zinc content in the lead concentrate from 5.6% to less than 2%. According to the announcement, the breakthrough positions Lewis Ponds for multiple near-term catalysts, including an updated Mineral Resource Estimate, completion of a Scoping Study, and additional drilling to expand the resource base.

The latest flotation testing has produced concentrates meeting commercial market standards with exceptional selectivity. Furthermore, the zinc concentrate consistently grades above 64%, while the lead-gold-silver concentrate achieved remarkable precious metals content with gold grades exceeding 16.7 g/t and silver exceeding 1,580 g/t.

Key performance improvements include:

• Enhanced gold recovery into the lead concentrate stream
• Significant impurity rejection, particularly zinc reduction in lead concentrate
• Excellent differential flotation between zinc and lead circuits
• High-quality, marketable products suitable for commercial offtake

The testing was conducted on two metallurgical domains within the orebody: the Disseminated (DIS) domain representing the primary orebody, and the Semi-Massive (SEM) domain forming the higher-grade portion. Both domains delivered superior results compared to historical benchmarks.

Comparative Performance Analysis

The 2025 Godolphin Resources Lewis Ponds metallurgical results demonstrate superior concentrate quality with improved metal recovery and reduced impurities, positioning Lewis Ponds as a potential producer of premium-grade concentrates for global markets.

Understanding Differential Flotation: The Key to Premium Concentrates

Differential flotation is a mineral processing technique that selectively separates different sulfide minerals based on their surface properties. At Lewis Ponds, this process enables the selective upgrading of gold and silver into the lead concentrate while achieving excellent zinc selectivity into a separate high-grade zinc concentrate.

The process works by using specific chemical reagents (collectors, depressants, and pH modifiers) to make target minerals hydrophobic (water-repelling) while keeping unwanted minerals hydrophilic (water-attracting). This allows valuable minerals to attach to air bubbles and float to the surface, where they're collected as concentrate.

Why this matters for investors: Superior differential flotation means Lewis Ponds can produce two distinct, high-value concentrate streams rather than a single lower-grade product. Consequently, this maximises revenue potential and provides flexibility in marketing to different end-users, whether zinc smelters or precious metals refineries.

Strategic Catalysts Position Lewis Ponds for Near-Term Value Creation

The announcement indicated that the metallurgical breakthrough directly enables several near-term value drivers that could significantly impact Godolphin's investment thesis. In addition, these Godolphin Resources Lewis Ponds metallurgical results provide a foundation for multiple upcoming initiatives.

Immediate Catalysts

• Updated Mineral Resource Estimate incorporating improved recoveries in gold equivalent calculations
• Scoping Study completion utilising new metallurgical results and pending updated MRE
• Additional drilling programme to test known mineralisation and Exploration Target areas

Resource Expansion Potential

The announcement noted that the company plans to drill-test two defined Exploration Target areas south of the main Lewis Ponds MRE, potentially extending the resource base beyond the current 9.83Mt resource (5.01Mt Indicated, 4.82Mt Inferred) grading 1.49g/t Au, 66.15g/t Ag, 2.46% Zn, 1.38% Pb, 0.15% Cu.

Managing Director Commentary
"These results will directly inform a pending update to the existing mineral resource estimate, which will include updated gold equivalent calculations. This upgraded resource will then underpin our Scoping Study—both of these initiatives are well advanced," said Managing Director Jeneta Owens.

Why Lewis Ponds Deserves Investor Attention

• 1,200m strike length with multiple mineralised lodes (Tom's, Spicer's, Torphy's)

Technical Advantages

• Superior metallurgical performance demonstrated through testing
• Multiple revenue streams from dual concentrate production
• Excellent mineral selectivity reducing processing complexity

Investment Highlight
Lewis Ponds combines scale, grade, and metallurgical advantages in a jurisdiction with excellent infrastructure and mining-friendly regulation. The improved concentrate quality directly enhances project economics and positions Godolphin for potential development success.

What Do These Results Mean for Commercial Viability?

The breakthrough Godolphin Resources Lewis Ponds metallurgical results have direct implications for the project's commercial potential. However, several factors contribute to the improved economic outlook beyond simple concentrate grades.

The ability to produce two distinct, high-grade concentrates eliminates the complexity and cost associated with treating mixed sulfide products. Furthermore, the reduced impurity levels mean potential customers can process these concentrates with minimal penalty charges, improving overall project returns.

Market demand for high-grade zinc concentrates remains strong, particularly as global zinc supply faces constraints. In addition, the precious metals content in the lead concentrate provides significant value uplift, with gold and silver contributing substantial revenue per tonne processed.

Conclusion: Breakthrough Results Drive Multiple Value Catalysts

Godolphin Resources has achieved a significant metallurgical breakthrough at Lewis Ponds, demonstrating the deposit's ability to produce premium-grade concentrates with superior metal recovery. The announcement indicates that the results directly support multiple near-term catalysts including an updated resource estimate, Scoping Study completion, and expanded drilling programmes.

With excellent infrastructure access in the proven Lachlan Fold Belt and 100% project ownership, Lewis Ponds represents a compelling development opportunity in Australia's established mining region. The combination of large-scale resources, superior metallurgy, and multiple value drivers positions Godolphin as a company worth monitoring as it advances toward potential development decisions.

Key Takeaway: Godolphin has demonstrated that Lewis Ponds can produce commercial-grade concentrates with enhanced precious metals recovery. With multiple catalysts approaching in the near term, investors should watch for the updated resource estimate and Scoping Study results that could further validate the project's development potential.
