Rose Uranium Breccia Pipe Project Update, Northern Arizona

VANE today announces a drilling update on the Rose uranium breccia pipe project (the "Rose Project") on which the exploration is carried out by its wholly-owned subsidiary, VANE Minerals (US) LLC in an agreement with Uranium One Exploration U.S.A. Inc. (“U1”).

Highlights

  • Three deep holes completed with the following main mineralised intercepts:
    • Hole 11-R-1; 1295.5 – 1394.5ft (99.0ft) averaging 0.06% eU3O8
    • Hole 11-R-2; 1436.5 – 1439.5ft (3.0ft) averaging 16.45% eU3O8
    • Hole 11-R-3; 1429.5 – 1439.0ft (9.5ft) averaging 0.64% eU3O8
  • Mineralisation in excess of +1% eU3O8 has been encountered on the project over a horizontal distance of 100ft and vertical extent of 250ft
  • Vertical extent of known mineralisation of 0.05% eU3O8 or greater expanded to 700ft

David Newton, CEO of VANE Minerals said "We are encouraged by these drilling results and the mineralisation that has been encountered. Further drilling will continue at Rose with the aim of establishing an NI 43-101 compliant resource, which will add to our existing resource of 1.118m pounds at our Wate project."

Background

The Company has completed three deep holes on the project indicating very encouraging results. Two of the three holes completed encountered +1% grade uranium mineralisation confirming previous historic drilling results at those grades. However, Hole 11-R-2 encountered an interval with a radiometric grade average of 16.45% eU3O8 with a maximum of 47.88% eU3O8, which is a substantially higher radiometric grade than had previously been encountered on any of the VANE breccia pipe projects.

The drill hole results, combined with data from previous drilling indicates that the pipe centre is easterly from all holes drilled to date. The +1% eU3O8 intervals in holes 11-R-2 and 11-R-3 are at the same depth (±1435ft) and approximately 60ft apart horizontally. Additionally, the current drilling verifies +1% eU3O8 mineralisation over a horizontal distance of 100ft and a vertical extent of 250ft when incorporating historic drilling. The vertical extent of mineralisation at grades 0.05% eU3O8 and higher has been increased to over 700ft. The mineralised intervals have been encountered over significant distances that, if continuous, would be sufficient to develop economic resources. Additional drilling is required to prove the continuity of the ore-grade mineralisation to establish NI43-101 compliant resources. The drilling programme is continuing with a view to establishing a resource.

The following details the mineralised intercepts of 0.05% eU3O8 or higher in the three holes drilled:

Hole 11-R-1
1295.5-1394.5ft – 99.0ft – 0.06% eU3O8 (max. 0.19% eU3O8)

Hole 11-R-2
1240.0-1247.5ft – 7.5ft – 0.15% eU3O8
1417.5-1421.0ft – 3.5ft – 0.46% eU3O8 (max. 0.88%)
1436.5-1439.5ft – 3.0ft – 16.44% eU3O8 (max. 47.88% eU3O8)
1445.5-1448.0ft – 2.5ft – 0.09% eU3O8
1457.0-1458.0ft – 1.0ft – 0.09% eU3O8

Hole 11-R-3
1072.0-1076.5ft – 4.5ft – 0.08% eU3O8
1099.0-1104.0ft – 5.0ft – 0.07% eU3O8
1172.0-1175.5ft – 3.5ft – 0.11% eU3O8
1429.5-1439.0ft – 9.5ft – 0.64% (max. 4.28% eU3O8)
1457.0-1458.5ft – 1.5ft – 0.08% eU3O8
1468.5-1470.0ft – 1.5ft – 0.09% eU3O8
1490.0-1491.0ft – 1.0ft – 0.12% eU3O8

Under the terms of the agreement with U1, VANE will manage the exploration of the Rose project and all expenditures will be shared equally with U1. Upon outlining a 1.0 million pounds eU3O8 NI43-101-compliant resource, VANE will make a cash payment of US$250,000 to U1. U1 will then assume management of the project and upon securing a mineral lease from the State of Arizona, VANE will make a final payment of US$250,000 to U1 in order to acquire a 50% interest in the Rose Project. The Rose Project is operated separately from the existing VANE-U1 joint venture.
