Surge Copper Achieves Remarkable Results for Berg Project Metallurgy
Impressive Metallurgical Test Results at Berg Project
Surge Copper Corp. is thrilled to share the exceptional outcomes of their recently concluded metallurgical testwork program for their 100%-owned Berg Project, a pivotal endeavor located in British Columbia. This program was undertaken to bolster pre-feasibility studies and demonstrate the efficacy of conventional flotation methods, confirming the project’s ability to yield saleable copper and molybdenum concentrates while enhancing the understanding of key recovery factors. The testing, performed by ALS Metallurgy Kamloops, spanned from mid-2024 through early 2025, showcasing significant advancements in recovery performance.
Key Highlights from the Metallurgical Program
The program involved over 1,350 kilograms of representative ore used to create three key composites reflective of expected mine material—namely hypogene, supergene, and transitional supergene. Additionally, 27 different variability composites were evaluated to cover the diverse rock and alteration types expected to be encountered throughout the proposed open pit. This extensive testing provided a comprehensive insight into the recovery prospects across various geological conditions, ensuring optimized flotation parameters were identified.
- Remarkable Recoveries: Locked cycle testing achieved an impressive 90.7% recovery of copper and 93.0% recovery of molybdenum in bulk concentrates with an average copper grade of 29.7%.
- Separation Efficiency: Excellent copper-molybdenum separation was confirmed, achieving molybdenum recoveries of 94.6% and 95.6% across the main hypogene and supergene composites, respectively.
- Consistency: High levels of consistency were observed across various composites for both copper and molybdenum, indicating reliability in the recovery process.
Advancing Technical Understanding and Economic Viability
This metallurgical testing was instrumental in reinforcing confidence in the proposed flotation circuit’s ability to consistently recover valuable resources, including not just copper and molybdenum, but also silver and gold. The insights gleaned from these tests will play a critical role in refining the recovery formulas for upcoming pre-feasibility work.
Commenting on these developments, Chief Executive Officer Leif Nilsson emphasized the significance of these results, noting that they represent a milestone in demonstrating the technical and economic potential of the Berg Project. With competitive copper grades and significant molybdenum recoveries, the results validate the proposed flowsheet and aim to enhance future recovery expectations.
Assessment of Recovery Characteristics
The comprehensive approach involved analyzing samples collected from 16 drill core holes at varying depths. The results were promising and provided a solid foundation for future explorations into different alteration types. Each master composite underwent multiple flotation tests targeting the extraction of copper, molybdenum, silver, and gold. Key testing variables included grind size, reagent schemes, pH, and energy density within flotation cells. The optimal conditions yielded outstanding recoveries across different composite types, solidifying the viability of the Berg Project.
Future Planning and Implications
The findings from this extensive metallurgical program not only enhance operational strategies but also lay the groundwork for subsequent technical studies. Surge Copper Corp. plans to refine the geometallurgical modeling for the Berg deposit, utilizing data from CuWAS assays to delineate the boundaries between supergene and hypogene mineralization. This improved approach is anticipated to boost the average copper and molybdenum recovery rates across the deposit, presenting a more favorable metallurgical outlook.
Environmental and Commercial Considerations
Moreover, the assays conducted reveal that the final concentrates are clean and well within the required commercial specifications, posing no concerns regarding deleterious elements that could affect marketability. As Surge Copper advances in their efforts toward a robust future, the metallurgical insights gained will contribute significantly to their long-term objectives.
