Adelong Gold Ltd (ASX:ADG) Provides Update on Lauriston Gold-Antimony Project
21 January 2026
Price Sensitive Announcement $
Highlights:
- A total of six diamond drillholes for 1,481.6m completed at the Comet prospect
- Structural and geochemical signatures show clear parallels with major Victorian gold systems, including Fosterville and Costerfield, where higher-grade mineralisation strengthens below arsenic-dominant upper zones.1
- Assays pending for all six drillholes
- Diamond drilling has commenced at the Yankee-Trojan prospect, approximately 3km to the north and along strike from Comet
Overview:
Adelong Gold Limited (ASX:ADG) has provided an update on their 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.
Drilling at Comet has intersected the mineralised structure, the Comet Shear, in all six drillholes, accompanied by well-developed arsenic halos that are characteristic of the upper levels of the major Victorian Au-As-Sb epizonal system. Gold mineralisation is associated with arsenopyrite, pyrite, stibnite, sphalerite and quartz veining within the Comet Shear.
Drilling has commenced at the Yankee-Trojan prospect located three kilometres to the north of Comet along the same regional trend. Assays for the six holes drilled at Comet are expected over the coming months.
Drilling Progress and Geological Observations
The first six diamond drillholes of the current program have now been completed, totalling 1,481.6m. All holes intersected significant zones of shearing and quartz-sulphide veining, with textures and mineral associations consistent with Victorian epizonal Au-As-Sb systems.
The mineralisation at Comet is hosted by an Ordovician turbidite sequence consisting of shale, mudstone, sandstone and minor granule quartz conglomerate sediments, which has been folded in a series of north-south striking concertina folds and regionally forms part of the Fosterville Sub-Domain, east of Bendigo. The west-dipping shear at Comet, known as the Comet shear, is associated with the gold mineralisation at the prospect. This high-grade gold discovery is located near the core of the Comet Anticline, where it is intersected by the Comet Shear Zone, a structural setting similar to that of the mineralisation present at Fosterville.
Assays for all drillholes are pending.
Ongoing Program and Next Steps
Diamond drilling recommenced in 2026 as part of the staged and systematic evaluation of the Lauriston Project. Pending results, the Company is prepared to expand the program beyond its initial scope (subject to ongoing geological assessment), including additional step-outs and deeper testing along the Comet Fault Zone and adjacent anticline. The program remains fully funded.
Field mapping and further surface geochemical sampling will also be undertaken to refine targets along the broader multi-kilometre structural corridor and to identify potential parallel structures.
Adelong Gold Managing Director, Ian Holland, said:
“Every hole drilled to date has intersected the host structure as predicted, with well-developed
arsenic halos, confirming that we are operating in the upper levels of a larger epizonal gold system. We intend to follow these initial drill holes with deeper drilling to test the potential of the system once all assay data has been returned and analysed. We view this systematic, technical progress as a positive step in the right direction toward making a discovery.
With drilling recommencing at the Yankee-Trojan prospect, we are maintaining momentum toward unlocking the broader potential of this project.”
