Highlights

  • The PCE high-grade subdomain expanded vertically by 94 metres, or 17%, to 644 metres.
  • Hole RK-26-290c1 recorded 19.5 cumulative metres above 10,000 counts per second.
  • A fifth drill rig was added to the Patterson Corridor East programme.

NexGen Energy Ltd (ASX:NXG) operates in the energy and resources sector and disclosed a series of operational and financial developments in its latest ASX release. Its shares were quoted at AUD 12.56 and increased 4.23% on 28 October 2026. The company’s announcement sets out the reported results for its stated financial or operating period, with information on Business activity, operational indicators and management’s disclosed next steps. The update covers separately reported operational, financial and project measures for the periods identified by the company.

Extension of the High-Grade Domain

NexGen Energy announced additional 2026 drilling results from Patterson Corridor East in Saskatchewan, Canada, expanding the interpreted vertical extent of its high-grade subdomain from 550 metres to 644 metres. Hole RK-26-293 extended mineralisation to a depth of 930 metres and returned a cumulative 4.7 metres above 10,000 counts per second, including 0.1 metre above 61,000 counts per second. The interpreted mineralised strike length remained around 210 metres because recent drilling focused principally on deeper extensions and the continuity of previously identified high-grade zones. Radiometric counts indicate instrument readings, not laboratory-assayed uranium grades.

Intersections and Geological Programme

Hole RK-26-290c1 intersected stacked uranium veins across a 40-metre section of the high-grade domain. It returned a cumulative 19.5 metres above 10,000 counts per second, including 5.2 metres above 61,000 counts per second. Hole RK-26-294 returned 6.9 cumulative metres above 10,000 counts per second, including 3.1 metres above 61,000 counts per second, near a previously reported drill intersection. Hole RK-26-296 expanded a shallower part of the interpreted mineralisation by 50 metres and recorded cumulative 3.5 metres above 10,000 counts per second, including 0.4 metre above 61,000 counts per second.

Drilling Schedule and Reporting Basis

NexGen said drilling at Patterson Corridor East resumed on 28 May 2026, with 20,138.7 metres completed to date toward a planned 42,000-metre programme. Eleven summer drillholes totalled 7,425.2 metres at the time of the update, and the company added a fifth drill rig. NexGen reported that samples were being submitted to the Saskatchewan Research Council Geoanalytical Laboratory for independent analysis and that assay results would follow. The announcement also referred to ongoing construction at the Rook I project. The disclosure was an exploration and project update, not a quarterly financial results release, and it did not provide Revenue or profit figures.

The reported figures and operational updates were provided by NexGen Energy Ltd (ASX:NXG) for the period identified in its filing. Forecasts, targets, proposed transactions and commissioning schedules are company statements rather than completed outcomes. Where the announcement describes conditions, dependencies or approvals, those qualifications remain part of the disclosed position. Financial measures and operating units are retained separately to avoid presenting different measures as interchangeable.

The 2026 exploration programme included radiometric readings obtained with a handheld spectrometer. The release reported that hole RK-26-294 was positioned near earlier high-grade intersections and that the recent results informed the updated interpreted mineralisation model. NexGen described the high-grade subdomain as still open in several directions and planned additional tests along the parallel trend at Patterson Corridor East. The company reported that mineralisation in the high-grade subdomain was, in its interpretation, generally about 70 metres shallower than the A2 High-Grade Zone. These findings concern geological exploration and require laboratory analyses before any chemical uranium-grade claims can be made.
