NexGen Energy Ltd (TSX: NXE) (ASX: NXG) has confirmed the discovery of a uranium mineralised zone below the known Arrow Deposit and at Camp East with drill assays from 2021.
- Below Arrow – multiple intersections of uranium mineralisation were made significantly below Arrow, including 0.10% U3O8 over 7.0 m in AR-21-268 from 1128 m to 1135 m down hole;
- Camp East – uranium concentration of 0.10% U3O8 in RK-21-140 from 166 m to 167 m down hole in association with brittle structure and hydrothermal alteration.
The company also confirmed has commenced 2022 drilling focused on regional exploration targets at the 100% owned Rook I project and an extensive geophysical programme over high priority areas of NexGen’s mineral tenure in the southwest Athabasca Basin, Saskatchewan.
“The intersection of mineralidation below the known Arrow Deposit and along trend at Camp East highlights the extent and potential for additional significant discoveries at Rook I,” CEO, Leigh Curyer, said.
“The geology team led by Grant Greenwood are well positioned for the 2022 drilling season which incorporates an extensive regional geophysical survey as a foundation for drilling in 2023 and beyond.”
Vice President, Exploration, Grant Greenwood, said the 2021 exploration drilling successfully intersected uranium mineralisation.
“In addition to mineralisation, these encouraging 2021 exploration results share alteration and structural similarities to those intersected in the discovery hole at Arrow (AR-14-01 or RK-14-21).
“NexGen is poised to advance high priority targets on the Rook I property in a systematic fashion from Arrow proximal outwards. The geophysical survey plans are strategic initiatives in developing highly prospective conductors in greenfield areas of the well situated NexGen mineral tenure in the emerging southwest Athabasca Basin uranium district.”
2022 Drilling
The Rook I project – home to the Arrow Deposit – hosts numerous, underexplored electromagnetic conductors (conductors) and structural corridors. While development of the Arrow Deposit is progressing optimally, NexGen’s 2022 exploration programme will focus on these underexplored targets towards making additional material discoveries. The programme will target high priority areas and build off the positive 2021 drilling results that intersected brittle structural disturbance and hydrothermal alteration on multiple conductors.
This drill programme – testing six conductive trends – is designed to evaluate prospective targets systematically with aggressive step-outs along high priority conductors.
Drilling targets areas (from West to East):
- Patterson Corridor (PLC) – Systematic testing along trend of Arrow, as well as at Camp East where 2021 drilling intersected anomalous radioactivity. This fertile trend has a strike length of approximately nine km on the Rook I property and remains highly prospective for further investigation.
- Mirror – Testing location with conductive response variation along the edge of a gravity low. The Mirror conductor is parallel immediately to the east of the Arrow conductor and of high priority.
- PLC East – Tests of segmented conductive responses on edges of gravity lows. PLC East is located proximal to the Arrow conductor with similar geometry.
- Derkson West – Follow-up of positive results from 2021 by testing along strike in both directions. Similar geometry to the PLC with a northeast-southwest trending conductor along magnetic gradient, coincident with local gravity lows.
- Derkson – Systematic drilling along prospective conductors in gravity lows. This high priority portion of the Derkson corridor for testing in 2022 contains discrete and strong conductive responses with interpreted structural disruptions.
- Derkson East – Targeting significant flexure of an underexplored conductor within a gravity low interpreted as localized structural disruption.
All target areas exhibit similar geophysical characteristics to Arrow, including strong conductive signatures with numerous off-sets coincident with discrete gravity lows and steep magnetic gradients.
