Freehill Mining Delivers Promising Magnetite Production at Yerbas Buenas

Freehill Mining Secures High-Grade Magnetite Sample from Yerbas Buenas Mine

Freehill Mining (ASX: FHS) has produced a high-quality magnetite bulk sample grading 65.75% Fe from its 100%-owned Yerbas Buenas Mine in Chile, demonstrating the project's potential for near-term production of premium iron ore.

Successful Bulk Sample Processing Confirms High-Grade Potential

The company has completed magnetic test work on a 400kg bulk sample of magnetite from its Chilean project, achieving an impressive grade of 65.75% Fe from material crushed to 6 millimetres. This result validates previous metallurgical work and confirms that quality concentrate suitable for sinter feed can be produced using relatively simple dry separation techniques.

Processing involved a methodical approach:

• 10 tonnes of material collected from four strategic locations within the open pit
• Three-stage crushing process reduced material size to 6mm
• Multiple passes through on-site dry magnetic separation drum refined the product
• Laboratory process included classification using 18-inch mesh and magnetic drum processing at varying frequencies (35Hz and 45Hz)

The test results showed excellent magnetic content and processing behavior, with the crushed ore reporting an overall grade of 43.84% Fe before final concentration to 65.75% Fe.

Chairman Ben Jarvis commented: "We are very encouraged by this result and material of this grade is perfectly marketable to a wide range of potential customers. After we complete some further test work as noted above, our intention is to recommence magnetite mining as soon as we complete the appropriate mine planning, define the necessary capex and determine the scale of the processing operation."

Understanding Magnetite Concentration and Its Market Significance

Magnetite concentration refers to the process of separating magnetic iron ore (Fe₃O₄) from surrounding rock using magnetic separation techniques. Unlike direct shipping ores (DSO) that can be mined and exported with minimal processing, magnetite requires processing to produce a high-grade product.

For investors considering Freehill Mining's Yerbas Buenas magnetite production potential, understanding the advantages of magnetite processing is important:

1. Value-add potential: While processing adds cost, it creates a premium product that commands higher prices in the market
2. Sustainability advantages: Magnetite concentrates typically produce fewer emissions in steel production compared to other iron ore types
3. Processing efficiency: Simple dry magnetic separation (as demonstrated at Yerbas Buenas) is significantly more cost-effective than complex wet processing required for other iron ore types

The ability to produce a 65.75% Fe product using relatively simple techniques is particularly significant as premium iron ore products (65%+ Fe) typically command substantial price premiums over standard 62% Fe benchmark prices in global markets. This approach parallels what other companies like Lithium Energy have achieved with their gold-copper opportunity in different minerals.

Future Plans and Development Timeline

Freehill is advancing several initiatives to move toward production at the Yerbas Buenas site:

• Further metallurgical testing: Additional test work on material crushed to 3mm and 5mm to determine if even higher-grade concentrate can be produced
• Mine planning: Advancing plans to recommence magnetite mining from the historical pit
• Permitting review: Assessing different permitting scenarios to expedite project development
• Capital expenditure analysis: Defining necessary investments to establish an optimally-scaled processing operation

The company has indicated that recommencing Freehill Mining Yerbas Buenas magnetite production is a priority, representing a low-capital, near-term revenue opportunity.

Simultaneously, Freehill's aggregates business continues to develop, with the team mobilising to a new site and additional expansion opportunities progressing well. In this regard, they follow a similar diversification strategy to Auric Mining which has seen record profits from its gold production efforts.

Investment Thesis: Multiple Revenue Streams with Near-Term Production Potential

Freehill Mining presents a compelling investment case based on several factors:

The demonstration of high-grade magnetite production capability positions Freehill as a potential supplier to the premium iron ore market, where environmental regulations increasingly favour higher-grade products that reduce emissions in steel production.

Why Investors Should Follow Freehill Mining

Freehill represents an opportunity to gain exposure to the premium iron ore market through a company with:

1. Proven product quality: Demonstrated ability to produce 65.75% Fe concentrate
2. Production optionality: Dual focus on magnetite and aggregates provides revenue diversification
3. Manageable capital requirements: Simple processing techniques minimise upfront investment
4. Clear path to production: Utilising existing infrastructure and historical mining areas
5. Strong management commitment: Board focused on unlocking value from higher-value commodities

With further test work underway and plans to recommence Freehill Mining Yerbas Buenas magnetite production advancing, Freehill is positioned to potentially transition from explorer to producer in the near term, offering significant upside potential as project milestones are achieved. Furthermore, investors interested in similar mining developments might want to follow critical resources' expanded discovery which shows comparable growth potential.

CEO Paul Davies added: "As well as the progress we are making at YB, our aggregates business continues to take shape with our team now fully focused on mobilising to our new site. Further expansion opportunities beyond this site are well-advanced and we are encouraged by the pipeline of potential new supply agreements."

Technical Analysis of Freehill's Magnetite Processing Approach

The successful production of high-grade magnetite concentrate at Yerbas Buenas demonstrates the technical viability of Freehill's approach. The company's processing methodology follows established principles but benefits from the high-quality nature of the deposit:

1. Crushing stages: The three-stage crushing process reduces particle size to optimise liberation of magnetite crystals from surrounding rock
2. Magnetic susceptibility: The strong magnetic properties of the Yerbas Buenas ore enables effective dry separation
3. Grade improvement: The significant increase from 43.84% Fe in crushed ore to 65.75% Fe in final concentrate demonstrates excellent upgrading potential

The company may achieve even better results with further refinement of crushing parameters and magnetic separation settings. Ongoing test work on material crushed to 3mm and 5mm could potentially yield higher Fe grades while maintaining acceptable recovery rates. This technical progress mirrors similar achievements seen in Hammer Metals' recent gold-copper discoveries in Queensland.

For investors, the relatively straightforward processing requirements of Freehill Mining Yerbas Buenas magnetite production represent a key advantage compared to more complex mineral processing operations that often face technical challenges and higher capital requirements. In addition, companies with high-grade results like Riversgold's Northern Zone project demonstrate how quality mineral concentrations can significantly enhance project economics.
