Atlas delivers record grade-thickness result as PLS drilling program expands

Paladin Energy has released a significant exploration update from its Patterson Lake South (PLS) Project in Saskatchewan, Canada, with drilling across three active zones: Atlas, Saloon East, and R1515W. The standout result comes from hole PLS26-782 at Atlas, which intersected 42.1m of total composite mineralisation including 26.4m grading 0.7% eU₃O₈ and 12.5m grading 1.8% eU₃O₈, representing the highest grade-thickness (GT) intersection returned from Atlas to date at 43.0 eU₃O₈ %.m. Atlas sits approximately 3.5km south of the Triple R deposit and forms part of the Saloon Trend.

All intersections are expressed as equivalent U₃O₈ (eU₃O₈) derived from calibrated downhole gamma probe measurements. Chemical assay verification has not yet been completed, so these results represent preliminary estimates within a JORC-compliant exploration programme.

Paul Hemburrow, MD and CEO

“The Atlas discovery is a significant exploration result that builds on the success of the Saloon East discovery in 2025. Both are located in the Saloon Trend to the south and broadly parallel with the Triple R deposit. These results demonstrate the potential scale of the PLS Project and the value in Paladin’s disciplined exploration strategy. We are continuing our extensive drilling program to upgrade resource confidence at Triple R, expand the resource and life of mine at PLS and to identify new discoveries in close proximity to PLS.”

Three-zone drilling campaign returns high-grade intersections

Atlas — 25 drillholes and a system growing in scale

25 drillholes totalling 8,755.4m have now been completed at Atlas, with this announcement covering 17 new drillholes since the 25 June 2026 update. Key results include:

  • PLS26-782: 42.1m total composite including 26.4m @ 0.7% eU₃O₈ and 12.5m @ 1.8% eU₃O₈, record GT result of 43.0 eU₃O₈ %.m
  • PLS26-762A: 13.0m total composite including 4.1m @ 3.0% eU₃O₈, with 2.6m @ 4.7% eU₃O₈
  • PLS26-773: 21.6m total composite including 3.3m @ 1.2% eU₃O₈ and 4.5m @ 1.1% eU₃O₈
  • PLS26-757 (step-out): 2.3m @ 1.2% eU₃O₈ approximately 270m northeast of the main Atlas discovery, indicating potential scale extension and a new target corridor

Mineralisation remains open, with ongoing drilling targeting further extensions.

R1515W — new mineralised zone identified 100m east of existing resource

20 drillholes totalling 6,250.5m have been completed at R1515W, targeting extensions beyond the current Mineral Resource envelope. Key results include:

  • PLS26-779: 12.7m total composite including 3.4m @ 0.7% eU₃O₈, approximately 100m east of the current R1515W Mineral Resource, representing a new zone
  • PLS26-784 (follow-up to PLS26-779): 3.8m total composite including 2.6m @ 1.8% eU₃O₈, with mineralisation remaining open and confirmed as a priority follow-up target
  • PLS26-751: 19.3m total composite including 12.6m @ 0.5% eU₃O₈
  • PLS26-756: 21.5m total composite including 11.4m @ 0.5% eU₃O₈

The fact that mineralisation remains open across this zone signals meaningful upside for resource growth beyond the current footprint.

Saloon East — discovery footprint continues to grow

Saloon East was discovered in August 2024 and sits approximately 3.5km southeast of the Triple R deposit. 28 drillholes have now been completed since discovery. Notable 2026 results include:

  • PLS26-729: 19.7m total composite including 8.7m @ 0.1% eU₃O₈
  • PLS26-719: 14.0m total composite including 5.5m @ 0.1% eU₃O₈
  • PLS26-727: 8.1m total composite including 5.4m @ 0.1% eU₃O₈

Mineralisation remains open along strike and at depth, reinforcing the company’s view that Saloon East has potential to contribute additional resources to the broader PLS Project.

Zone Hole ID Total Composite (m) Key Grade Interval eU₃O₈ (%)
Atlas PLS26-782 42.1m 12.5m @ 1.8% (inc. within 26.4m @ 0.7%) Record GT: 43.0 %.m
Atlas PLS26-762A 13.0m 4.1m @ 3.0%, inc. 2.6m @ 4.7% 3.0% / 4.7%
Atlas PLS26-773 21.6m 3.3m @ 1.2% and 4.5m @ 1.1% 1.2% / 1.1%
R1515W PLS26-779 12.7m 3.4m @ 0.7% (~100m east of current resource) 0.7%
Saloon East PLS26-729 19.7m 8.7m @ 0.1% 0.1%

What is equivalent U₃O₈ and why does it matter for exploration investors?

Equivalent U₃O₈ (eU₃O₈) is a uranium grade estimate derived from calibrated downhole gamma probe measurements, not from laboratory chemical assay. A gamma probe records the natural radioactivity of the rock as it is lowered down a drillhole, and that radiation response is converted into a uranium grade estimate using project-specific calibration factors.

This method is widely used in early-stage uranium drilling because it delivers rapid, real-time grade indications during active campaigns. Drillers can make faster follow-up decisions without waiting weeks for laboratory results. The trade-off is that eU₃O₈ values are preliminary estimates, not confirmed grades. Chemical assay verification occurs subsequently and may confirm, adjust, or refine the reported figures, so investors should treat these results as indicative rather than final.

Grade-thickness (GT), expressed as %.m, is calculated by multiplying the average grade of an interval by its length in metres. It gives a single metric for comparing the overall economic significance of different intersections. A higher GT means more uranium contained within a given intercept. The 43.0 eU₃O₈ %.m GT result from PLS26-782 is the highest recorded at Atlas to date, which is precisely why this hole stands out from the broader campaign.

Anatomy of the Record Drill Hit: PLS26-782

PLS Project strategy — building toward a Tier-1 development outcome

Paladin’s exploration strategy at PLS has three distinct objectives: resource extension drilling within the Triple R uranium zones, prospect delineation drilling converting discoveries like Atlas and Saloon East into future development targets, and regional exploration to identify entirely new discoveries.

All three zones drilled in this campaign sit in close proximity to the Triple R deposit, supporting the potential for resource consolidation and life-of-mine extension as the programme matures. The company describes PLS as a Tier-1, high-grade, shallow project in northern Saskatchewan’s Athabasca Basin. Paladin also holds a 75% ownership of the Langer Heinrich Mine in Namibia, which is currently producing and supplying uranium to major nuclear utilities.

Drilling continues with stated objectives to upgrade resource confidence at Triple R, expand the overall resource, extend the life of mine at PLS, and identify additional near-project discoveries. No specific timelines or production targets have been disclosed in the source announcement.

Frequently Asked Questions

What is equivalent U₃O₈ (eU₃O₈) and how reliable is it?

Equivalent U₃O₈ (eU₃O₈) is a uranium grade estimate derived from calibrated downhole gamma probe measurements rather than laboratory chemical assays — it provides rapid, real-time grade indications during active drilling campaigns but should be treated as preliminary until chemical assay verification is completed, which may confirm or adjust the reported figures.

What is grade-thickness (GT) in uranium drilling and why does it matter?

Grade-thickness (GT), expressed as %.m, is calculated by multiplying the average grade of a drill intercept by its length in metres, giving a single metric to compare the economic significance of different intersections — a higher GT means more uranium contained within a given intercept, which is why the record 43.0 eU₃O₈ %.m result from hole PLS26-782 at Atlas is the standout result in this announcement.

Where is Paladin Energy's Patterson Lake South project located?

Patterson Lake South (PLS) is located in Saskatchewan, Canada, within the Athabasca Basin — one of the world's premier uranium districts — with the Atlas and Saloon East discoveries sitting approximately 3.5km south of the Triple R deposit along the Saloon Trend.

What does it mean that mineralisation is "open" at Atlas, Saloon East, and R1515W?

When mineralisation is described as "open," it means drilling has not yet reached the boundary of the mineralised zone — the uranium-bearing rock continues beyond the last drillhole, indicating the deposit could be larger than currently defined and that further drilling may expand the resource footprint.

How does the Atlas discovery relate to Paladin's existing Triple R resource at PLS?

Atlas sits approximately 3.5km south of the Triple R deposit along the Saloon Trend and is one of several new discoveries Paladin is advancing as part of a strategy to expand the overall PLS resource base, extend the project's life of mine, and potentially consolidate multiple zones into a single Tier-1 development outcome.
