Patronus Resources Limited confirms high-grade uranium at its Thunderball Project in the Northern Territory. Re-assay results reveal standout intervals (e.g., 10m at 2.5% U3O8), prompting a new diamond drill program to expand the deposit—an exciting development for unlocking further district-scale value.
Patronus Resources has confirmed extensive high-grade uranium mineralisation at its Thunderball Project in the Northern Territory’s Pine Creek region. A comprehensive re-assay program, undertaken as part of a broader technical review by SRK Consulting, attested to the deposit’s exceptional grade and continuity. Highlighted results include a 10‐meter intersection recording 2.5% U₃O₈ from 145 meters depth—with a standout 1‐meter segment at 16.7% U₃O₈—as well as additional intercepts of 10 meters at 1.2% U₃O₈ (featuring 1 meter at 17.2% U₃O₈) and 13 meters at 0.7% U₃O₈ (including 0.5 meter at 14.7% U₃O₈). These figures reinforce the view that Thunderball holds significant potential as a major asset for Australia’s uranium sector.
The re-assay is part of an ongoing effort to upgrade the deposit’s classification to JORC 2012 standards, building on the original 2004 resource estimate of 1.69 million pounds of U₃O₈ at an average grade of 924ppm. An initial extensional six-hole diamond drill program has now commenced, targeting both the Main Lode and the upper mineralised zone with planned depths ranging between 150 and 350 meters. The deposit, hosted within a sub-unit of the Gerowie Tuff and structurally controlled by northwest-dipping lodes, is set within a region already noted for its proximity to several world-class uranium deposits, enhancing the overall district-scale opportunity in Pine Creek.
The technical work behind the re-assay involved detailed re-logging, density measurements from 20 diamond holes, and umpire re-assays from 34 holes, leading to an improved geological and structural model. The comprehensive data not only underscores the strength of Thunderball’s current intercepts but also lays the groundwork for future resource expansion. The company is poised to update its Mineral Resource Estimate once the current drill program concludes in the next four to six weeks.
From a market sentiment perspective, the news lends itself to a bullish outlook. The confirmation of high-grade, continuous mineralisation alongside the initiation of an extensional drill program suggests a strong potential for resource expansion and enhanced project value. However, there are factors that may temper optimism. The deposit remains in the exploration phase, and the forthcoming updated resource estimate will be essential in validating these early favorable indications. Additionally, the broader uranium market and any potential volatility in commodity prices might influence investor sentiment.
Overall, the technical milestones achieved at Thunderball signal promising growth for Patronus Resources while acknowledging the inherent uncertainties linked to early-stage exploration and market fluctuations.
