Surefire Resources Uncovers High-Grade Gold Discovery at Yidby LOOT Prospect

Surefire Resources Uncovers High-Grade Gold in a Previously Overlooked Rock Type at Yidby's LOOT Prospect

Surefire Resources NL (ASX: SRN) has released follow-up assay results from on-surface float rock sampling at the newly discovered LOOT Prospect, part of its 100% owned Yidby Gold Project in the Mid-West of Western Australia. The results confirm high-grade gold mineralisation within a previously unrecognised Albitite lithology, with samples returning grades up to 13.19 g/t gold across a strike length of 165 metres — all within a rock type only recently identified as a gold-bearing host at this project.

This announcement builds on the initial discovery reported on 26 March 2026 and represents a meaningful step forward in understanding the geometry and potential scale of this new mineralised system.

High-Grade Results Across the Board — No Blanks in Albitite

One of the most notable aspects of this announcement is the consistency of results. Every Albitite float rock sample collected at the LOOT Prospect returned gold values. This is a meaningful signal for investors — it suggests that gold mineralisation is not isolated or erratic within this lithology, but appears to be pervasive across the sampled area.

Key observations from the results include:

• 12 of 14 samples returned gold grades above 1 g/t Au
• 7 of 14 samples returned grades above 5 g/t Au
• Peak grade of 13.19 g/t Au recorded at sample LT022
• Duplicate assays (where taken) show strong repeatability, confirming result reliability
• Only one sample (LT025 at 0.18 g/t) returned a sub-economic grade

"All assays within this new lithological style of gold mineralisation — gold in Albitite rock — provide gold values."

Understanding Albitite: The Hidden Gold Host

Understanding Albitite is central to appreciating why the Surefire Resources high grade gold discovery at Yidby LOOT Prospect represents a significant development for investors.

Albitite is a light-coloured, sodium-rich rock composed predominantly of albite (a sodium-rich feldspar mineral). Unlike rocks formed directly from molten magma, Albitite forms through a process called sodium metasomatism. This occurs when hot, sodium-rich fluids migrate through existing rock, replacing original minerals with albite.

At Yidby, this process is reported to occur along structural corridors such as shears, fault systems, and fractures within the region's high-grade metamorphic terrain. These fluid pathways are precisely the kinds of structures that also focus and trap gold mineralisation.

Furthermore, the Albitite at LOOT contains common relict sulphide casts measuring 2 to 3mm in size. These are visual indicators that sulphide minerals were once present in the rock and have since been preserved within the Albitite matrix, often carrying associated gold.

Why Does This Matter to Investors?

Several factors make this discovery significant:

1. Proven Gold Host: Albitite is a recognised gold-hosting lithology in some of Western Australia's most productive goldfields, including the New Celebration Gold Deposit on the Boulder Lefroy-Golden Mile fault system, St Ives Camp at Kambalda, Binduli near Kalgoorlie, and Bardoc north of Kalgoorlie.

2. Structural Extensions: Because Albitite forms along structural corridors, mineralisation typically has both down-dip and along-strike extensions — meaning what is observed on surface is unlikely to represent the full extent of the system.

3. Hidden from Conventional Exploration: Soil geochemistry from the transported overburden at Yidby does not display gold anomalism, which means this mineralisation style was invisible to conventional surface geochemical exploration methods. The discovery was only made possible by directly sampling the rock itself.

A New Discovery Hidden in Plain Sight

One of the more intriguing aspects of this story is what was missed by previous explorers. The nearby Cashens open pit, which was mined in 1975, has been re-examined by Surefire. Upon inspection, the company identified previously unrecognised Albitite rock in the ore zone at the base of that historical pit.

This raises a compelling question: could the Albitite-hosted gold style have been present all along, but simply not identified as a separate and mappable lithological host?

The LOOT Prospect sits in close proximity to the Cashens Find Prospect. Both now exhibit gold mineralisation within the same Albitite-rich, grey fine-grained felsic rock. The spatial and geological linkage between these two prospects suggests the possibility of a broader Albitite-hosted gold corridor across the Yidby project area.

In addition, the company's immediate follow-up objective was designed specifically to understand the orientation and dimensions of this new mineralised system. The identification of Albitite over a 165-metre strike length in this current sampling round is a solid early indication of the system's lateral extent.

Geophysical Detection: A Potential New Exploration Tool

Surefire has identified a potentially powerful tool for tracing Albitite occurrences across the project. Albitite has a density of approximately 2.63 g/cm³, which is meaningfully lower than the surrounding ultramafic host rocks, which carry a density of approximately 3.0 g/cm³.

This density contrast means that Albitite bodies could potentially be detected through high-resolution gravity geophysics, which would identify them as negative gravity anomalies against the denser ultramafic background.

This is a material point for exploration targeting. If Albitite can be mapped geophysically, Surefire may be able to identify buried or concealed Albitite zones across the broader Yidby terrain without relying solely on surface sampling — opening up a potentially systematic, scalable exploration approach.

What Comes Next — Planned Follow-Up Work

The Surefire Resources high grade gold discovery at Yidby LOOT Prospect is still at an early but highly encouraging stage. The current work has defined surface expressions of high-grade Albitite gold mineralisation. The next phase of work is expected to focus on:

• Follow-up drilling to test the subsurface extension of the LOOT Prospect Albitite mineralisation at depth
• Along-strike sampling to further define the lateral dimensions of the Albitite gold corridor
• High-resolution geophysical surveying to assess whether gravity methods can map Albitite zones across the broader Yidby project area
• Reinterpretation of historical drill core from the Cashens Find and surrounding prospects in light of the newly recognised Albitite lithology
• Assessment of the Cashens open pit Albitite to determine whether the historical mining intersected this style without recognising it

The Investment Case: Why LOOT Could Be a Significant Project-Level Catalyst

The Surefire Resources high grade gold discovery at Yidby LOOT Prospect adds a new and previously unrecognised dimension to the Yidby Gold Project. However, several aspects of this discovery are worth highlighting for investors evaluating the investment case.

Consistent High-Grade Results

An average gold grade well above typical discovery-stage float sampling, with 12 of 14 samples above 1 g/t and a peak of 13.19 g/t, speaks to a genuine mineralised system rather than anomalous scatter.

A New Mineralisation Style

Identifying Albitite as a gold-bearing host at Yidby opens an entirely new exploration vector that was previously invisible to soil geochemistry-based programmes. The project's prospectivity has, therefore, effectively expanded.

Does the Structural Setting Support Extensions?

Albitite forms along shear zones and fault corridors — environments known to carry mineralisation over significant distances both along strike and at depth. The 165-metre strike extent identified so far is a starting point, not a boundary.

Historical Mining Context

The identification of Albitite in the base of the 1975 Cashens open pit introduces the possibility that the historical operation may have mined the margins of a system that was never fully understood or followed up with modern techniques.

100% Project Ownership

Surefire holds a 100% interest in the Yidby Gold Project tenements (E52/2390 and E52/2426), subject only to a 2% royalty on gold production payable to Beau Resources Pty Ltd — meaning shareholders retain full exposure to exploration upside.

Geophysical Targeting Potential

The density contrast between Albitite and surrounding ultramafic rocks offers a prospective geophysical detection method, potentially enabling cost-effective regional targeting of covered Albitite zones.

Why Investors Should Watch Surefire Resources Closely

The LOOT Prospect represents exactly the kind of discovery that reshapes the exploration narrative of a small-cap gold company. The grades are genuinely high, the lithological identification is scientifically grounded, the historical context adds intrigue, and the structural setting provides a logical basis for expecting more mineralisation at depth and along strike.

Critically, Surefire is not recycling old news. This is a new mineralisation style within a project that was already being actively advanced, and it appears to have been hiding in plain sight — in a rock type that soil geochemistry simply cannot detect.

Drilling results from LOOT will be the next major catalyst to watch. If the Albitite gold mineralisation has any meaningful depth extension consistent with its structural setting, the project's scale and significance could increase materially from here.

"The Surefire Resources high grade gold discovery at Yidby LOOT Prospect has uncovered a new style of high-grade gold mineralisation at its 100% owned Yidby Gold Project, with surface samples returning grades up to 13.19 g/t gold in Albitite rock across a 165-metre strike. With drilling follow-up planned, historical pit reinterpretation underway, and a geophysical detection tool on the table, the LOOT Prospect could represent a significant and scalable new discovery. Investors should watch closely for drill results that test the system at depth."
