Lac Gold (ASX:LAC) — has released fresh diamond drilling results from the Astoria deposit and said they feed into a resource update targeted for the first quarter of 2027.

Lac Gold Limited reported on 29 October 2026 further drilling results from the Astoria deposit at its wholly owned Rouyn Gold Project in Quebec, within the Abitibi gold region of Canada. The company said the latest holes identified additional mineralisation, including intervals that sit outside the main ultramafic rock unit that hosts much of the known gold.

The headline intersections

The strongest result came from hole AS-26-827, which the company reported as 10.0 metres at 8.28 grams per tonne of gold from 195.0 metres downhole, including 4.0 metres at 15.80 grams per tonne. That interval sits inside a wider zone of 50.0 metres at 2.03 grams per tonne from 160.5 metres.

Hole AS-26-826 returned 9.0 metres at 5.20 grams per tonne from 232.0 metres, including 1.5 metres at 27.00 grams per tonne. Hole AS-26-824 intersected 3.25 metres at 5.34 grams per tonne and 1.35 metres at 5.78 grams per tonne, within a broader 31.55 metres at 1.39 grams per tonne from 141.95 metres. Hole AS-26-819 reported 8.0 metres at 2.75 grams per tonne, including 3.5 metres at 4.74 grams per tonne, inside 25.5 metres at 1.02 grams per tonne from 196.5 metres. Hole AS-26-825 returned a narrow 0.54 metres at 26.70 grams per tonne, along with 10.0 metres at 1.86 grams per tonne from 327.1 metres.

All of these are downhole lengths. The company has not established true widths, and it said the assay data were not adjusted and no top cuts were applied.

A possible shift in the geological picture

Lac Gold said gold mineralisation extends beyond the main ultramafic unit into the surrounding sedimentary rocks, known as wackes. It said hole AS-26-827 is contributing to a revised geological interpretation in which mineralisation may be more extensive than previously modelled. That is an interpretation under review rather than a confirmed change to the deposit, and the company noted that further drilling is required to establish the continuity and extent of mineralisation.

Where the 2026 program stands

The company said it has drilled 81 holes for 32,519 metres in the 2026 program. Of these, 68 holes have been logged and 66 sampled and sent for analysis. Assays have been received for 52 complete holes totalling 18,814 metres, while 14 holes covering 6,682 metres are at the laboratory awaiting results. A further 13 holes, or 5,687 metres, have been drilled and are awaiting logging. That leaves a substantial volume of data still to come, so the results released so far do not represent the full program.

Diamond drilling is continuing at Astoria. Lac Gold said it is targeting extensions of known mineralisation as well as new geological settings.

The resource backdrop

Astoria already carries a JORC 2012 Mineral Resource of 1.666 million ounces of gold at 3.28 grams per tonne from 15.8 million tonnes in total. Of that, 976,000 ounces are in the Indicated category (9.2 million tonnes at 3.30 grams per tonne) and 690,000 ounces are Inferred (6.6 million tonnes at 3.24 grams per tonne). The estimate is dated April 2025 and was reported to the ASX in October 2025.

Exploration drilling results are not themselves Mineral Resources. The new intersections have not been added to that estimate, and the company has not said what they will mean for its size or classification.

Next steps and risks

The main confirmed milestone is an update to the Mineral Resource Estimate, which is being prepared by Measured Group and is targeted for completion in the first quarter of 2027. Lac Gold said the update will incorporate these results. It cautioned that the update may change tonnage, grade, contained gold and classification, so the outcome is uncertain until the estimation work is complete.

The company also included the usual forward-looking statement warnings, noting that no assurance can be given that future studies will support development. Remaining assays are still due from the holes at the laboratory.
