Northern Star’s New Discoveries Strengthen Global Gold Growth Path

Highlights

• Exploration continues to advance across Australian and US gold hubs.
• New zones emerge near existing mine sites.
• Integration of the Hemi project progresses steadily.

Northern Star Resources continues to strengthen its exploration footprint across Australia and the US, uncovering new mineralised zones and progressing long-term resource development plans.

Northern Star’s Expanding Exploration Success Across Australia and the US

Northern Star Resources (ASX:NST) has reported ongoing exploration progress across its extensive portfolio, delivering new geological insights and strengthening its long-term footprint within the gold sector. With activity spanning Western Australia, the Pilbara region, Kalgoorlie and Alaska, the company continues to reinforce its exploration momentum in a year where major ASX mining stocks remain in focus for their development activity on the ASX stock market.

The company highlights a strong pipeline of drilling programs surrounding near-mine zones, underground extensions, newly emerging lodes, and strategic regional prospects. These operational themes position Northern Star as a key contributor to gold-focused indices including the ASX100, ASX200 and the wider ASX300, with its projects generating ongoing interest within the Australian resources landscape.

Exploration Momentum Driving Long-Term Resource Growth

Northern Star has maintained an emphasis on organic expansion around its major assets. Drilling continues to focus on near-mine targets that support future development options while strengthening existing resource models. This includes:

• deep extensional drilling
  
  
• surface-based identification of new structures
  
  
• improved definition across high-priority mineralised zones
  
  
• continued work across regional sites located near established mills and processing hubs
  
  

These exploration priorities advance the company’s wider strategy to convert resources over time, extend production horizons and consolidate the operational potential of its Australian and US assets.

Kalgoorlie Region – Expanding Depth and Target Diversity

New Discoveries at KCGM

The Kalgoorlie Consolidated Gold Mines (KCGM) zone continues to be one of the most active exploration areas for the company. At Fimiston South, drilling has pushed the mineralisation footprint deeper, extending several lodes to new vertical ranges. Recent drilling suggests stronger continuity than earlier models had indicated.

The updated geological interpretation opens additional development options, supporting future underground access and enhancing the long-term value of the broader Kalgoorlie operations.

Emerging Prospects at Mt Charlotte

A newly defined exploration zone named Golden Goose has been identified north of the Northern Orebody. This zone has delivered broad mineralised intervals, confirming structural potential and supporting additional follow-up drilling over the coming year.

The introduction of Golden Goose underscores growing confidence in the depth and scale of the Kalgoorlie district, adding another layer of opportunity within a historically rich mining corridor.

Growth from Ballarat–Last Chance and Hercules

Drilling west of the Red Hill deposit at the Ballarat–Last Chance prospect continues to return strong widths of mineralisation, adding new geological understanding around the western flank of the system.
In addition, the Hercules area has produced further high-grade intersections, supporting resource model upgrades and sharpening the outlook for future extraction options.

Yandal Region – New Extensions Near Established Workings

Jundee Maintains High-Grade Momentum

The Jundee operation remains one of Northern Star’s cornerstone assets, and recent drilling has mapped out new extensions across the Deakin and Barton areas. These targets showcase narrow but high-grade intersections, reinforcing the structural attractiveness of the region.

These results continue to support the view that Jundee hosts multiple stacked vein systems, extending well beyond initial geological interpretations.

Thunderbox Uncovers Additional Depth Continuity

At Thunderbox, drilling around the Wonder West zone, positioned just near the main Wonder underground area, has continued to reveal mineralisation that extends further down-plunge. These results broaden the underground growth scenario for Thunderbox and reinforce the strength of the mineralised corridor.

This area remains a central focus for continued drilling, as the structural trend offers consistent targets along strike and at depth.

Pogo, Alaska – High-Grade Mineralisation Strengthens the Region

Central Link and Structural Understanding

The Pogo operation in Alaska has continued to deliver encouraging drilling outcomes, particularly across the Central Link corridor. Recent surface drilling has helped refine geological models, mapping the structural connections between Central Lodes and the Goodpaster region.

This enhanced structural knowledge strengthens the understanding of mineralised pathways across the broader Pogo system.

East Deep and Star Zone Continue to Impress

Underground drilling at East Deep has produced additional high-grade intersections, upgrading confidence in resource continuity.
At the Star prospect, infill drilling confirmed thick and rich mineralised zones that closely resemble the geological attributes of the primary Pogo lodes.

These ongoing results position Pogo as an important growth engine within Northern Star’s international portfolio.

Pilbara Region – Integrating Hemi and Advancing Regional Growth

Northern Star’s acquisition of the Hemi Development Project has added a significant new dimension to its portfolio. Integration of Hemi into the company’s gold inventory is underway, with updated resource and reserve models being prepared for inclusion in the next Annual Statement.

High-Grade Zones Between Diucon and Crow

Drilling between the Diucon and Crow areas has uncovered stronger-than-anticipated mineralisation at depth, with both narrow high-grade intervals and wider moderate-grade sections. These findings reinforce expectations around the scale and depth continuity of the Hemi system.

Regional Discoveries at Mt Berghaus

Located northwest of Hemi, the Mt Berghaus prospect has also produced encouraging intersections, supporting geological views that the broader Mallina Basin may host additional satellite discoveries.
These results expand the regional footprint and highlight the longer-term upside around Hemi, complementing the development pipeline being built across the Pilbara.

Strengthening Outlook Through Sustained Organic Growth

Northern Star continues to focus on long-term resource conversion, near-mine drilling and the strategic growth of major production centres. With its broad geographical footprint and expanding exploration success, the company remains aligned with ongoing interest in ASX dividend stocks and gold-exposed names within Australia’s key market indices.

The combination of deep extensional drilling, regional discovery drilling, and ongoing project integration reflects a consistent theme of organic expansion across multiple jurisdictions.

As exploration continues into the coming financial year, Northern Star remains positioned to advance its portfolio and work toward building long-term gold development pathways across both Australia and the US.
