Adelong Gold (ASX:ADG) reports visible gold in second Lauriston diamond hole

Adelong Gold has reported early progress from the initial stages of its diamond drilling program at the Lauriston Gold and Antimony Project in Victoria, noting that visible gold has been observed in the second hole, AC2502, with assays pending.

The activity forms part of the broader 3,000 metre drill program across the Comet and Yankee Trojan prospects, as set out in the company’s 8 October 2025 announcement, and continues to build upon the structural and geochemical model previously outlined for the epizonal gold antimony system the company is targeting.

Highlights

• First two diamond drillholes completed for a combined total of approximately 444.6 metres.

• Both holes intersected multiple zones of shearing, quartz veining and sulphide bearing mineralisation consistent with the high grade Au Sb system.

• Minor visible gold observed in AC2502 within Comet shear at 100.5 metres.

• Sampling ongoing with assay results expected before the end of December.

• Third hole AC2503 underway as a 100 metre step out to the north along the Comet Trojan structural corridor.

• Drilling to continue into early 2026 to systematically test the multi kilometre strike potential.

The company reports that both drillholes intersected strong zones of shearing and quartz sulphide veining consistent with the epizonal Au Sb system at Lauriston.

Core from both holes is being sampled and will be dispatched for priority analysis, and figures included in the release illustrate the structural textures observed in AC2502, although these figures represent observed core textures only and should not be interpreted as a proxy for grade.

Drillhole AC2501 extended the Comet Shear down dip by approximately 80 metres and demonstrated the consistency of the host structure, while AC2502 recorded visible gold within a structurally complex interval containing brecciated and stylolitic quartz veins with coarse grained arsenopyrite, pyrite and trace stibnite.

According to the release, this is the first recorded instance of visible gold in the current program, and continuity of mineralisation will be assessed as drilling progresses along strike and as assay results are received.

A table of drillhole collar locations confirms that AC2501 reached 309.4 metres, AC2502 reached 135.2 metres and AC2503 is currently in progress.

The third hole has commenced as a 100 metre step out to the north, targeting interpreted structural repetitions and down plunge extensions along the Comet Trojan corridor, which represents more than three kilometres of underexplored strike as noted in the company’s 8 October 2025 announcement.

Adelong Gold Managing Director Ian Holland said,

“Observing visible gold in AC2502 is a positive geological observation and reinforces our view that Lauriston hosts a prospective mineral system. These first holes are delivering the structural, geological and mineralogical signatures we expect from an epizonal Au Sb environment. As drilling steps out along the Comet Trojan corridor, we are building important momentum toward unlocking the broader potential of this project.”

Drilling is planned to continue into early 2026 as part of the staged and systematic evaluation of the Lauriston Project, and pending results, the company states that it is prepared to expand the program beyond its initial scope, subject to ongoing geological assessment.

Field mapping and further surface geochemical sampling are also planned to refine targets along the broader multi kilometre structural corridor.
