    Is the Market Missing Arkle’s Uranium Upside?

    Two Types of Uranium Mineralisation. One £10.2m Valuation. What’s the Market Missing?

    Dear Reader,

    Arkle Resources (LSE:ARK) has just confirmed two different styles of uranium mineralisation at its Erongo project in Namibia.

    It marks a substantial step forward in the company’s expanded strategy.

    And with Arkle currently valued at around £10.2m, the question now is whether the market is yet assigning enough value to that emerging uranium opportunity.

    We think there’s a case to suggest it isn’t.

    Part of that may simply reflect the weaker sentiment and volatility we’ve seen across the wider metals and mining space—something no junior explorer can completely escape.

    Even so, Arkle’s 21.38% interest in the Stonepark zinc-lead project in Ireland arguably provides substantial backing to the current valuation on its own, as we’ll explain.

    That makes Namibia increasingly important as a potential additional source of value.

    • And with another round of funded drilling approaching, Arkle now has the chance to build on these first results and show just how significant that opportunity could become.

    Namibia Starts to Deliver

    As a reminder, Arkle acquired an 85% interest in four licences covering 540km² in Namibia’s Erongo uranium provinceearlier this year.

    It’s an established uranium district, home to major deposits including Rössing and Trekkopje, with Arkle targeting two different styles of mineralisation across its ground.

    And over the past couple of weeks, maiden drilling has now confirmed both.

    The most encouraging results so far have come from theULG target, where uranium is hosted in leucogranite rocks.

    • Eight of nine holes intersected uranium above 100 parts per million (“ppm”) uranium oxide (“U₃O₈”) across an area roughly 1.4km long by 600m wide. You can see them in the map below:

    The standout, R069, returned 41m at 141ppm U₃O₈, including 4m at 240ppm, while three holes also ended in mineralisation—meaning the system remains open at depth.

    But what’s important here isn’t necessarily the grade.

    As Arkle’s CEO Rory Harding explained in our latest StockBox interview, deposits of this type in the region are typically bulk-tonnage, open-pit systems.

    So, the key questions are how much continuous mineralisation Arkle can define, how the thicker higher-grade zones connect and, ultimately, how much volume the system can build.

    A Second Uranium System

    Arkle has also confirmed a completely different style of uranium mineralisation at an area of its licences called Paleo East.

    Here, uranium occurs in shallow ancient river channels rather than within granite. Importantly, this is the same broad deposit style seen at the nearby Trekkopje project.

    • Drilling returned uranium across 2.9km of the channel, with all twelve mineralised intervals starting within just five metres of surface.

    The best result was 6m at 102ppm U₃O₈ from surface, including 4m at 136ppm.

    Again, this is more about potential scale than spectacular grades.
     
    Arkle has tested less than a quarter of the interpreted 12.7km channel, leaving plenty of ground to investigate if follow-up work continues to connect the mineralisation.

    • And when taken together, the two targets give Arkle more than one route to building value in Namibia.

    ULG has the potential to develop into a sizeable primary uranium system and remains open, while Paleo East provides a second, very shallow target with most of its interpreted strike still untested.

    What Comes Next?

    The potential scale here is what makes the next phase particularly important.

    Arkle is planning another fully funded drilling programme, expected to begin in November subject to contractor availability:

    1. At ULG, the focus will be on stepping out, drilling deeper and better understanding the continuity of the thicker mineralised sheets. The longer-term goal is to progress towards a maiden mineral resource estimate in 2027, an important milestone if Arkle can demonstrate enough continuity and volume.

    2. At Paleo East, further drilling will be combined with shallow trenching between existing holes, giving the company a relatively low-cost way to start filling the gaps across the channel.

    Meanwhile, Rory told us that further trenching, sampling and mapping are already underway, with similar ULG and paleochannel targets also being assessed elsewhere across the wider licence package.

    The Stonepark Opportunity

    There’s more, too.

    Namibia isn’t the only opportunity under the Arkle umbrella—there’s also Stonepark.

    The Irish project already hosts an inferred resource of 5.1Mt at 11.3% combined zinc and lead, with Arkle retaining a 21.38% interest alongside operator Group Eleven Resources.

    But recent drillinghas also opened up new ground, including 2.8m at 8.3% Zn+Pb from a new zone around 550m from the existing resource.

    Group Eleven has continued drilling at Stonepark, meaning there’s still potential for that existing resource story to grow while Arkle advances Namibia.

    Hannam & Partners has previously valued Arkle’s Stonepark interest at $21.7m.

    That’s an analyst valuation rather than cash in the bank, of course, and there’s no guarantee the market will ultimately value the asset the same way. But it’s still comfortably above Arkle’s entire current £10.2m market capitalisation.

    That suggests the market may currently be assigning relatively little value to the uranium opportunity emerging in Namibia.
    There’s still work to do.

    Arkle doesn’t yet have a uranium resource, and the next drilling needs to show that these first results can be extended into mineralisation with enough continuity, grade and scale to support one.

    But that’s also where the opportunity lies.

    If the next programme expands ULG, strengthens Paleo East and moves Arkle closer to a maiden resource, Namibia could start to command more value.

    Add that to an existing interest in Stonepark that continues to advance, and £10.2m starts to look like a pretty interesting valuation from which to be entering the next phase of work.
