The Pick

Killi Resources has taken another important step towards unlocking the broader potential of its Lodestone Iron Ore Project in Western Australia, completing a high-resolution magnetic survey across a 25-kilometre mineralised corridor that could hold the key to substantial resource growth.

The survey comes as the company advances an extensive drilling and metallurgical testing campaign, with the ambition of transforming Lodestone from an established magnetite resource into a potentially significant supplier of premium-grade iron ore concentrate.

For investors, the attraction is not simply the scale of the mineralised system. It is the unusual characteristics of the magnetite itself, which could provide Killi with a valuable point of difference in an increasingly quality-conscious global steel industry.

A 25km Opportunity That Has Barely Been Scratched

Killi's latest exploration milestone involved completing 1,844 line kilometres of drone-based magnetic surveying across the full 25km strike of known magnetite mineralisation at Lodestone, located in Western Australia's Mid-West iron ore district.

The survey was conducted using closely spaced east-west flight lines, just 50 metres apart, providing detailed geophysical coverage designed to improve the company's understanding of the underlying mineralisation.

This matters because magnetite is strongly magnetic, making high-resolution magnetic surveys particularly effective at identifying geological structures and potential extensions to known orebodies.

The new data will help refine the geological interpretation of the main Lodestone magnetite body while potentially identifying additional parallel mineralised zones in both the hanging wall and footwall.

In practical terms, Killi is looking beyond its established deposit to determine whether the broader system contains additional orebodies capable of supporting future resource expansion.

Processing of the survey data is underway, with the full interpretation expected in the coming weeks.

Importantly, magnetic anomalies are not mineral resources. Any newly identified targets will require drilling and geological validation before their potential contribution can be established.

Nevertheless, the survey provides another piece of the geological puzzle as Killi attempts to establish just how large the Lodestone mineralised system might be.

An Existing 110 Million Tonne Foundation

Unlike many early-stage explorers pursuing conceptual targets, Killi already has a substantial mineral resource from which to build.

Lodestone hosts a JORC-compliant Inferred Mineral Resource Estimate of 110 million tonnes, with a Davis Tube Recovery mass recovery of approximately 33% and an iron concentrate grade of 69%.

Perhaps the most compelling aspect is that this resource has been defined across only approximately 5km of the broader 25km magnetite trend.

That leaves around 20km of strike outside the currently defined resource footprint, although the presence of magnetite along the trend does not establish that the remaining ground will support economically recoverable mineral resources.

For investors, the opportunity lies in demonstrating sufficient continuity, grade and recovery characteristics to justify meaningful increases in the existing resource inventory.

Killi is pursuing that objective through a planned 20,000-metre drilling program incorporating both resource definition and extension drilling.

The initial diamond drilling component has been completed, comprising nine holes totalling 1,333 metres.

Reverse circulation drilling is continuing, targeting both infill areas and extensions of the existing mineralisation.

The campaign is intended to support a resource upgrade in the coming months, potentially providing the market with a clearer indication of Lodestone's ultimate scale.

Why Premium Magnetite Could Command Attention

While resource expansion is central to Killi's strategy, the quality of the prospective final product could prove equally important.

Lodestone's magnetite is described as coarse and hydrothermally recrystallised, characteristics that distinguish it from many conventional magnetite deposits.

According to Killi, these properties allow the ore to produce high-purity concentrates grading between 68% and 70% iron at a relatively coarse grind size.

This is significant because magnetite processing typically involves crushing and grinding to liberate iron-bearing minerals from waste material.

Grinding can represent a substantial component of processing energy consumption and operating costs.

If Lodestone's coarse-grained mineralisation can consistently achieve high iron grades without requiring exceptionally fine grinding, it could offer processing advantages over deposits requiring more intensive mineral liberation.

However, the magnitude of any cost advantage remains to be established through detailed metallurgical testing and subsequent economic studies.

The strategic appeal extends to the steel industry, where premium iron ore products are increasingly relevant to lower-emissions production technologies.

Killi is positioning Lodestone towards high-value magnetite concentrate markets associated with emerging electric arc furnace steelmaking requirements.

While electric arc furnaces themselves do not directly require iron ore concentrate, high-purity concentrates can potentially serve as feedstock for direct reduced iron production, which can supply metallic iron to electric arc furnaces.

That distinction matters when assessing Lodestone's potential role in the evolving steelmaking supply chain.

Metallurgical Testing Takes Centre Stage

Alongside exploration, Killi has commenced a detailed program of metallurgical and ore characterisation work.

Diamond drill core is undergoing geotechnical, geophysical and geochemical assessment, while physical characterisation studies are progressing.

Concentrate material is also being prepared for pelletisation test work, an important step in evaluating its potential suitability for downstream ironmaking applications.

These activities will help determine whether Lodestone's favourable geological characteristics translate into a commercially attractive processing proposition.

For investors, the results could prove particularly important because a large iron ore resource is only part of the equation.

Recovery rates, concentrate quality, processing requirements, infrastructure access and eventual capital intensity will ultimately influence the project's economic potential.

Killi's regional positioning in the Mid-West iron ore district also provides a relevant infrastructure consideration. The company's project mapping identifies road and rail infrastructure near the southern end of the mineralised corridor, although commercial access arrangements and transport economics have not been established.

What Investors Should Watch Next

Killi is approaching a potentially news-rich period at Lodestone.

The interpretation of its completed magnetic survey should provide a more detailed picture of the 25km mineralised system and help prioritise additional drilling targets.

Meanwhile, ongoing reverse circulation drilling will test opportunities to expand and better define the existing resource.

Metallurgical results, ore characterisation studies and pelletisation testing will provide further evidence about the potential quality and market suitability of Lodestone concentrate.

The next resource estimate will be particularly important in assessing whether the company's exploration strategy is translating into additional defined tonnes.

There are, however, material uncertainties. Lodestone's existing resource remains in the Inferred category, and the project has yet to demonstrate commercial viability through a completed economic assessment. Further drilling, engineering, environmental work and potentially substantial development funding would be required before production could be contemplated.

The Bigger Picture

Killi's acquisition of Lodestone has added a substantial iron ore opportunity to its Australian exploration portfolio, which also includes gold and copper interests in Western Australia and Queensland.

The immediate investment narrative, however, is increasingly centred on the potential size and quality of its Mid-West magnetite asset.

With 110 million tonnes already defined, extensive drilling underway and detailed geophysical coverage now completed, Killi is assembling the technical information needed to test its resource growth ambitions.

The attraction is straightforward: an established high-grade concentrate resource sitting within a much larger mineralised corridor.

The challenge is converting that geological opportunity into additional JORC resources and, ultimately, a credible development proposition.

For Killi, the next few months could help determine whether Lodestone is simply a sizeable magnetite deposit or the foundation of a considerably larger premium iron ore project.
