VANCOUVER (miningweekly.com) – Uranium explorer and development company Denison Mines has extended the new high-grade unconformity-hosted mineralisation up-dip and about 250 m along strike to the north-east of the Gryphon deposit, which is part of the 60%-owned Wheeler River uranium project, in the Athabasca basin of Northern Saskatchewan.
The Toronto-based company said it has completed a 30-hole drilling campaign over the summer months totalling 12 466 m, which has returned preliminary radiometric equivalent grades (eU3O8) from drill hole WR-670D2 of 4.3% over an interval of 4.3 m, from mineralisation occurring immediately above the sub-Athabasca unconformity.
The new zone of E series unconformity mineralisation now extends about 80 m horizontally along the unconformity and remains open along strike to the north-east and south-west.
This result adds to previous unconformity mineralised intercepts, which include 5% eU3O8 over 4.7 m in drill hole WR-689D3 and 1.2% eU3O8 over 1.4 m in drill hole WR-690D3.
Denison said it plans to use the data in an upcoming resource update for the Gryphon deposit.
Wheeler River is a joint venture of Denison (60%), Cameco (30%), and JCU (Canada) Exploration (10%).
