Accelerate Resources Gravity Survey Reveals Structural Controls at Woodie Woodie North

Gravity Survey Defines Structural Controls at Accelerate Resources' Woodie Woodie North Manganese Project

Accelerate Resources Limited (ASX: AX8) has reported that a high-resolution ground gravity survey across the Gingarrigan and El Largo manganese corridors at its Woodie Woodie North Manganese Project has identified a network of subsurface structures aligning with numerous mapped manganese outcrops. According to the ASX announcement, several larger high-grade outcrop clusters occur at or near interpreted structural intersections, giving the company a clearer basis for drill targeting ahead of its planned maiden drilling program in September 2026, subject to heritage clearance and required approvals.

For investors, the key point is that the manganese occurrences appear to follow a geological pattern rather than being randomly scattered. That matters because a defined structural model can improve drill targeting and may increase the chances that future drilling tests the most prospective parts of the system.

"The gravity work has given us a much clearer picture of the structural plumbing beneath Gingarrigan and El Largo. The key result is that the manganese outcrops are not randomly distributed, many align with interpreted structures, and some of the larger outcrops occur in areas of structural intersection," said Luke Meter, CEO of Accelerate Resources.

"With gravity, LiDAR and detailed mapping now integrated, we have a much stronger geological framework for targeting the upcoming drill program."

What Did the Gravity Survey Show?

In the announcement, Accelerate said Atlas Geophysics collected 2,440 gravity stations across a 4.5km by 2km survey area covering the core Gingarrigan and El Largo corridors. The data was then processed and interpreted by Southern Geoscience Consultants, with the first vertical derivative (1VD) method used to sharpen near-surface structural detail.

When those interpreted gravity structures were compared with Accelerate's mapped manganese outcrops, the company reported a clear spatial relationship:

• Numerous manganese occurrences sit on or immediately adjacent to interpreted structures
• Larger outcrop clusters, including around Rancor and the Gingarrigan-Gingerbread area, occur in zones of greater structural complexity
• Some of the larger clusters are positioned at or near interpreted structural intersections

The company said this pattern supports a fault-hosted or fault-fill hydrothermal manganese model. In simpler terms, the interpretation is that faults may have acted as pathways for mineral-bearing fluids, while bends or intersections in those structures may have provided the space for manganese to accumulate.

That interpretation remains a geological model until it is drill tested. Nevertheless, the survey appears to give Accelerate a more focused way to rank drill targets across the two corridors.

Why Does the Woodie Woodie Comparison Matter?

A major feature of the announcement is the comparison with the nearby Woodie Woodie manganese district, located approximately 55km south of the project area. According to Accelerate, published geological studies of Woodie Woodie show a strong relationship between high-grade manganese mineralisation and faulting.

The company cited work by Jones, McNaughton and Grguric (2013), which describes high-grade ore bodies at Woodie Woodie as occurring on steep secondary and tertiary structures branching from larger basin-controlling faults. Those larger faults are interpreted to have acted as conduits for manganese-bearing hydrothermal fluids.

Accelerate stated that the structural pattern emerging at Gingarrigan and El Largo is consistent with this district-scale setting. For investors, that does not prove the same outcome will occur at Woodie Woodie North, but it does provide a relevant geological analogue in an established manganese camp.

This distinction matters considerably. Explorers often compare early-stage targets to nearby mines, but the relevance depends on whether the underlying geology actually looks similar. In this case, according to the announcement, the new gravity data provides evidence that the local structural pattern may resemble the fault-controlled setting seen in the nearby producing district.

Understanding Ground Gravity Surveys and Why They Matter

How Does a Ground Gravity Survey Work?

A ground gravity survey measures tiny changes in the Earth's gravitational field caused by differences in the density of rocks below the surface. Dense rocks create a slightly stronger gravity signal than lighter rocks.

These differences are extremely small, so the survey uses sensitive instruments at many individual stations across a target area. Geoscientists then process the data to identify patterns that may point to buried faults, rock boundaries, basin shapes or other subsurface features.

What Questions Can Gravity Data Answer?

For non-specialist investors, the value of gravity data is practical rather than abstract. It can help answer questions such as:

• Where are the main structures below surface?
• Do those structures line up with surface mineralisation?
• Where do faults intersect or become more complex?
• Which parts of a corridor are most likely to justify drilling first?

At Gingarrigan and El Largo, Accelerate used the 1VD processing method. This is a way of sharpening shallow features in the gravity dataset so near-surface structures stand out more clearly.

Furthermore, if mineralisation is controlled by faults, then identifying those fault pathways can make the difference between broad, low-confidence drilling and more targeted testing of the strongest geological positions.

Below is a plain-English guide to the main technical terms used in the announcement:

LiDAR and Orthophotography Add Surface Precision

The ASX announcement also outlined the completion of a high-resolution airborne survey by Pegasus Airborne Systems across roughly 7km² of the core Gingarrigan and El Largo area.

That programme delivered:

• High-resolution LiDAR topographic data
• 2.5cm-resolution orthophotography
• An average LiDAR point cloud density of approximately 247 points per square metre

This dataset gives the company a much clearer surface model. According to Accelerate, the LiDAR, orthophotography, field mapping and gravity interpretation are now being combined into a single targeting model.

In practical terms, this integrated work may help the company:

1. Map the shape and extent of manganese outcrops more accurately
2. Trace structural corridors beneath shallow cover
3. Identify sites where several favourable structural features coincide
4. Plan access and drilling in the Pilbara terrain more efficiently

For investors, this is relevant because better surface and subsurface data can improve the quality of first-pass drilling. Early-stage drilling results often depend as much on target selection as on the underlying mineral system itself.

Project Scale and Existing Resource Base

The Woodie Woodie North Manganese Project covers 432km² in Western Australia's East Pilbara and sits along the same broader manganese corridor as the operating Woodie Woodie Manganese Mine. Accelerate said the tenure package includes seven mapped large-scale manganese corridors extending across 42km of strike.

Importantly, the company already holds an existing Inferred Mineral Resource Estimate (MRE) from other parts of the project, based on prior drilling across Barra North (Area 1), Barra South (Areas 3 and 4), and Area 42.

Existing Mineral Resource Estimate

The company noted that the MRE is reported at a 15% Mn cut-off and that all categories are Inferred.

Accelerate also referred to an Exploration Target of 5.3Mt to 10.7Mt at 10% to 19% Mn across extensions to the resource areas and additional prospects. Crucially, the announcement stated that Gingarrigan and El Largo are not included in either the current MRE or Exploration Target.

That distinction is important. It means the targets now being refined by gravity and LiDAR work are outside the currently defined resource inventory and therefore represent separate exploration potential. At the same time, the Exploration Target remains conceptual in nature, as stated in the announcement, and there has been insufficient exploration to estimate a Mineral Resource for those target areas.

What Happens Next?

According to the announcement, Accelerate's next steps are focused on converting the new datasets into final drill targets. The company said it plans to:

• Finalise the integrated structural interpretation using gravity, LiDAR, orthophotography and field mapping
• Rank priority structural intersections and manganese-bearing corridors for drill testing
• Complete the final RC drill design for the Gingarrigan-Gingerbread area following heritage clearance and required approvals
• Continue interpretation and mapping along the broader El Largo trend
• Begin its maiden drilling programme in September 2026, subject to heritage clearance and required approvals

Near-Term Project Timeline

This sets up a defined news flow for the project over the coming period, with the main catalyst likely to be the start of drilling and any assays that follow.

Why Does This Update Matter in Investment Terms?

The announcement does not report drilling results or a new resource. However, what it does provide is a stronger geological framework for where drilling is likely to occur next.

Several points stand out:

• Improved target confidence: The company now has geophysical support for the idea that manganese mineralisation is structurally controlled
• Relevant district analogue: The structural style is described as consistent with the nearby Woodie Woodie manganese camp
• Additional upside outside current resources: Gingarrigan and El Largo are outside the existing 1.2Mt at 19.1% Mn MRE and the 5.3Mt to 10.7Mt Exploration Target
• Defined near-term catalyst: Maiden drilling remains expected in September 2026, subject to approvals

For investors following ASX manganese exploration, the update is most relevant as a targeting milestone. It suggests Accelerate is moving from surface mapping and early evidence into more disciplined drill planning.

The next material test will be whether drilling confirms that the surface manganese occurrences continue at depth along the interpreted structures and structural intersections. If that continuity is demonstrated, it may support additional resource growth beyond the currently defined areas at Woodie Woodie North. If not, the structural model will need to be reassessed. For now, the gravity survey provides a clearer basis for that test.
