Kodiak Reports Positive Results from Metallurgical Testwork on the MPD Project

Rhea-AI Summary

Kodiak Copper Corp. (KDKCF) reported positive initial metallurgical testwork results from its MPD copper-gold project in British Columbia. The tests demonstrated robust flotation recoveries of up to 89.9% copper, 74.1% gold, and 76.0% silver. The company successfully produced high-grade copper concentrate exceeding 26% copper with significant gold grades between 6.2 and 16.9 g/t. The testing, conducted on three composite samples representing different grade profiles, showed low concentrations of deleterious trace metals, suggesting potential for clean, high-quality concentrates. The mineralization proved amenable to conventional processing methods, with the majority of copper present as chalcopyrite. This milestone supports the project's advancement toward a maiden resource estimate expected in the near future.

Highlights

• Robust flotation rougher recoveries of up to 89.9% copper, 74.1% gold, and 76.0% silver;

• Flotation testing confirmed that a high-grade copper concentrate exceeding 26% copper can be produced from the MPD mineralization;

• The copper concentrates had significant gold grades of between 6.2 and 16.9 g/t, enhancing the value of the concentrate;

• Gold contained in pyrite presents an opportunity to further improve gold recovery. This and other optimization opportunities will be explored in the next phase of metallurgical testing; and

• Low concentrations of deleterious trace metals were observed suggesting the potential for clean, high-quality concentrates.

Claudia Tornquist, President and CEO of Kodiak said, "These results are a significant milestone in the advancement of the MPD project. They confirm that the copper mineralization at MPD is amenable to conventional processing and reinforce the potential for a high-quality, saleable copper concentrate with significant gold content. This further de-risks the project as we continue to work towards a maiden resource estimate, a major milestone and value catalyst for Kodiak which is expected in the near future."

The introductory metallurgical testwork program was designed to develop an understanding of the metallurgical responses of the mineralized material at MPD as well as to determine baseline copper and gold recoveries. A flotation program, incorporating automated mineralogy which uses advanced analytical techniques to quantitatively determine mineral composition, was designed to develop a fundamental understanding of the factors that drive recovery and concentrate grade.

Sample Selection & Methodology

Three composite samples of half split core were collected for the metallurgical testwork program. The composites were selected to build a cross section of grades from six zones at the MPD project: Gate/Prime, Man, Dillard, West, Adit and South/Mid. Early-stage pit optimization work was referenced to determine representative grades to support the sample selection. The three composites were chosen to represent low grade, average grade, and high-grade samples from the six zones. The samples were named MPD North High Grade (MPDNHG), MPD North Low Grade (MPDNLG), and MPD South (MPDS).

Each of the three composites were initially subjected to automated mineralogy using the industry standard TESCAN TIMA platform. The mineralogy identified that the majority of the copper is in the form of chalcopyrite with a small amount of bornite and chalcocite.

The flotation testwork utilized a proven, industry-standard copper flotation flowsheet that included rougher and cleaner stage flotation tests to recover copper, gold, and silver. The rougher is a primary flotation stage intended to separate valuable minerals from barren rock. The cleaner is a secondary stage intended to concentrate the valuable minerals to a high-grade final concentrate product. A total of 24 flotation tests utilizing common reagents were performed to confirm metallurgical performance and provided valuable data to support optimization of recovery and final concentrate grade.

Metallurgical Test Work Results

The results demonstrated copper rougher recoveries of 89.0% and 89.9% for the MPDNHG and MPDS samples respectively, and 82.3% copper rougher recovery for the MPDNLG sample. Gold showed good recovery by flotation, with between 59.7% and 74.1% reporting to the rougher concentrate.

Cleaner flotation tests were conducted to demonstrate that saleable copper concentrates bearing high gold credits (considered >22% Cu) could be produced from each of the samples. The concentrates produced in the testwork were of good quality, returning copper grades of between 22% to 26.7% and gold assays between 6.2 g/t (low gold grade feed) to 16.9 g/t. Analysis of the concentrates also show that the concentrates have low concentrations of deleterious elements.

The results of the testwork are presented in Table 1.

It was seen during the program that a portion of the gold in the samples is associated with pyrite, as is observed at other Quesnel Belt porphyry systems, indicating that standard sulphide flotation recovery methods are acceptable for producing gold in concentrate. Increasing the pyrite content in the copper concentrate, while maintaining a saleable concentrate grade, has been identified as an opportunity to maximize gold recoveries and will be explored in future testwork.

The initial testwork confirmed that the mineralization at MPD responds well to standard processing methods. Further metallurgical testwork will build on the knowledge developed during this initial program to identify opportunities to improve recoveries.

Kodiak is focused on its 100% owned copper porphyry projects in Canada and the USA that have been historically drilled and present known mineral discoveries with the potential to hold large-scale deposits. The Company's most advanced asset is the MPD copper-gold porphyry project in the prolific Quesnel Terrane in south-central British Columbia, Canada, a mining district with producing mines and excellent infrastructure. MPD has all the hallmarks of a major, multi-centered porphyry district with the potential to become a world-class mine. Work to date has outlined multiple substantial mineralized zones across the property, including several zones with near-surface, high-grade mineralization. A maiden resource estimate for MPD is planned in 2025 and with known mineralized zones open to expansion and more target areas yet to be tested, Kodiak continues to systematically explore the project to build critical mass and make the next discovery. The Company also holds the Mohave copper-molybdenum-silver porphyry project in Arizona, USA, near the world-class Bagdad mine.

Kodiak's founder and Chairman is Chris Taylor who is well-known for his gold discovery success with Great Bear Resources. Kodiak is also part of Discovery Group led by John Robins, one of the most successful mining entrepreneurs in Canada.
