Great Boulder Resources Delivers High-Grade Results from Western Australia Drilling

Highlights:

• Great Boulder Resources reports strongest-ever gold intercept from Eaglehawk within the Side Well project.

• Drilling programs at Eaglehawk and Mulga Bill confirm new high-grade mineralized zones.

• Exploration continues with aircore drilling as the company awaits final assay results.

The mining and natural resources sector plays a vital role in the global economic framework, supplying essential raw materials that drive infrastructure development, manufacturing, and energy generation. In Australia, this sector remains central to regional economies and trade, with exploration activity often focused on identifying high-grade mineral deposits that contribute to long-term resource security.

Eaglehawk Drilling Results

Great Boulder Resources (ASX:GBR) has recorded significant progress at its Eaglehawk drilling site, part of the Side Well project in Western Australia. The company's reverse circulation drilling program delivered a standout gold intersection, with grades reported as the highest in its exploration history. These results followed previous strong returns from the same project area, positioning Eaglehawk as a key contributor to the company’s growing geological database.

At Eaglehawk, a key intercept was observed over a narrow width but with exceptionally high-grade gold mineralization. This section included a dense concentration of mineralization within quartz-sulphide veins. The host lithology and structural orientation indicate a mineralized corridor that may warrant further exploration focus.

Mulga Bill Site Contributions

In parallel with Eaglehawk, the nearby Mulga Bill site also returned notable drill results. Multiple intercepts were recorded from depths associated with deeper mineralization zones. These included zones of visible sulphide content and structural deformation, which align with previous geological modeling for the region.

The structural relationship between the mineralization at Mulga Bill and Eaglehawk continues to support regional exploration planning. These sites together contribute to the broader Side Well project's footprint, enhancing the project's strategic value.

Exploration Activities and Geological Interpretation

Great Boulder Resources is continuing its exploration efforts with an ongoing aircore drilling campaign. The latest drilling phase targets extensions along lithological boundaries and vein contacts, particularly within dacite-intruded zones. The identification of new vein structures and gold-rich intervals underscores the refinement of geological models based on recent data.

Assay results from remaining reverse circulation holes are pending, and further exploration will be guided by geological trends observed in both Eaglehawk and Mulga Bill zones. The presence of quartz-sulphide veins within well-defined structural corridors is driving renewed mapping and sampling efforts across the project area.

Market Presence and Sector Relevance

As a resource-focused entity listed on the Australian Securities Exchange under the ticker GBR, Great Boulder Resources continues to strengthen its presence in Western Australia’s mineral exploration landscape. Its activities contribute to the broader performance landscape of the ASX 200, with mineral exploration companies playing a notable role in sector-specific indices.

The Side Well project’s location near established mining infrastructure in Meekatharra provides logistical advantages. Regional accessibility supports streamlined operations and facilitates rapid response to new discoveries. Additionally, the results reported from the recent drilling program reinforce the company’s data-driven approach to advancing its exploration initiatives.

Engagement within Resource Communities

Activity from Great Boulder Resources has generated interest within mining circles, with technical discussions emerging around the geological characteristics of the reported drill zones. Public forums and technical summaries highlight the exploration success, fueling ongoing interest in resource sector developments within Australia.
