South Arrow

The Rook I project hosts the South Arrow Discovery located 400 m South of the Arrow Deposit, discovered in July 2017.


Aggressive step out drilling at the recently discovered South Arrow has intersected significant high-grade mineralization in multiple holes, and has extended the strike length and vertical extent of high-grade mineralization to 290 m and 185 m, respectively. High-grade uranium mineralization occurs as accumulations of semi-massive to massive pitchblende similar to that seen in the High-Grade Domains of the Arrow Deposit.

  • AR-17-166c1 (250 m up-dip and southwest of discovery hole AR-17-151c1) intersected 20.5 m at 1.19% U3O8 (182.0 to 202.5 m) including 3.5 m at 6.21% U3O8 (191.5 to 195.0 m) and an additional 24.5 m at 1.46% U3O8 (212.5 to 237.0 m) including 5.0 m at 4.21% U3O8 (221.0 to 226.0 m) and 4.0 m at 3.33% U3O8 (229.5 to 233.5 m).
  • AR-17-160c1 (203 m up-dip and southwest of discovery hole AR-17-151c1) intersected 13.0 m at 2.18% U3O8 (221.5 to 234.5m) including 4.0 m at 6.79% U3O8 (227.0 to 231.0 m) and an additional 19.5 m at 0.34% U3O8 (191.5 to 211.0 m) including 4.0 m at 1.01% U3O8 (201.5 to 205.5 m).
  • AR-17-163c1 (190 m up-dip and southwest of discovery hole AR-17-151c1) intersected  22.5 m at 1.07% U3O8 (241.0 to 263.5m) including 3.9 m at 5.56% U3O8 (256.4 to 260.3 m).
  • AR-17-178c1 intersected 11.0 m at 2.17% U3O8 (149.0 to 160.0 m) including 3.5 m at 6.73% U3O8 (150.5 to 154.0 m) only 142 m below surface.
