Adelong Gold (ASX:ADG) Lauriston Gold-Antimony Project Drilling – Visible Gold is Observed in Second Diamond Hole with Assays Pending

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 100.5m, validating historic exploration results
• 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 

 

Adelong Gold Limited (ASX:ADG) (Adelong Gold or the Company) is pleased to provide an update on ongoing diamond drilling at the Lauriston Gold-Antimony Project in Victoria.

The program forms part of the broader campaign outlined in the Company’s announcement dated 8 October 2025, which detailed the planned 3,000 metre drill program across the Comet and Yankee-Trojan prospects.

The current work continues to build upon the structural and geochemical model described in that announcement, including the presence of epizonal gold-antimony mineralisation analogous to Fosterville and Costerfield¹.

The first two diamond drillholes have been completed for a combined 444.6 metres and intersected strong zones of shearing and quartz-sulphide veining consistent with the epizonal Au-Sb system at Lauriston. Visible gold was recorded in AC2502 within a structurally complex interval with assays pending.

Core from both holes is being sampled and will be dispatched for priority analysis, with results expected before the end of December.

 

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.”

 

¹ The presence of mineralisation and exploration results at Fosterville and Costerfield does not guarantee, and should not be construed as indicative of, similar mineralisation or results at the Lauriston Project.

About us:

Adelong Gold Limited (ASX:ADG) is an Australian mineral exploration company focused on advancing its high-grade Victorian assets - the Apollo Gold and Antimony Project and the Lauriston Gold and Antimony Project. Both projects lie within highly prospective geological corridors and display strong potential for significant epizonal Au-Sb discoveries.

The Lauriston Project, acquired in 2025, is a 28,700-hectare tenement adjacent to the Fosterville Mine. It hosts the high-grade Comet discovery, with drill results including 8.0m at 104 g/t Au and 5.9m at 15.3 g/t Au. With minimal historical drilling and a structural setting comparable to Fosterville’s Swan Zone, Lauriston offers strong near-term exploration upside. Diamond drilling at Lauriston commenced in October 2025 and is targeting the multi-kilometre Comet-Trojan corridor adjacent to the high-grade Fosterville Mine.

The Apollo Project, also acquired in 2025, lies within Victoria’s highly prospective Melbourne Zone and demonstrates strong bulk-tonnage gold potential, with mineralisation open at depth and along strike. The project also hosts antimony-bearing stibnite, akin to the nearby Costerfield and Sunday Creek deposits.

The Adelong Goldfield Project in NSW covers 70km² and hosts a 188,000oz gold resource. A staged farm-in agreement with Great Divide Mining (ASX:GDM) was executed in March 2025, with GDM earning a 51 percent interest by targeting near-term production.

Adelong also holds a strategic lithium portfolio in Brazil, including tenements in the ‘Lithium Valley’ and Borborema regions. where early exploration has identified promising pegmatite targets. This diversified portfolio provides exposure to high-grade gold-antimony exploration and the global energy transition, positioning Adelong for long-term value creation.
