Arizona Breccia Pipe Uranium Exploration Update
VANE Minerals Plc ('VANE' or 'the Company') is pleased to provide an update on
its breccia pipe uranium exploration activities in northern Arizona, operating
as VANE Minerals (US) LLC, its wholly-owned uranium subsidiary.
The schedule of the drilling programme for the Miller, Big Red, and Red Dike
Pipes has been modified in order to complete the work obligations required by
the State of Arizona within the stated time constraints of the exploration
permits. Exploration programmes are required to be completed within one year of
approval. Due to limited rig availability,and adverse weather one of the three
drill holes planned for the Miller Pipe was completed and the rig was then moved
on to Big Red, followed by Red Dike, in order to satisfy those work commitments.
DRILLING PROJECTS
Miller Pipe Project
Hole 691-1 was completed to a depth of 1445 feet (441m). The hole was designed
to offset, 60 feet (18m) to the northeast, the mineralised zones encountered in
holes 1640-3 and 1640-5 drilled by Energy Fuels Nuclear, Inc in the 1980's. Hole
691-1 deviated 44 feet (13m) northeast from the collar and out of the pipe and
was barren of uranium mineralisation. The geological results indicate the
high-grade mineralisation encountered in the old holes is contained in the
annular ring fractures of the pipe and that hole 691-1 is outside the annular
rings. Further exploration drilling will focus on the annular rings as well as
the pipe interior and the next hole is planned for the inferred western portion
of the pipe, which has not yet been tested. Annular ring mineralisation
accounted for substantial uranium tonnage in other pipes in the district,
particularly the Orphan Mine, which historically produced 5 million pounds of
uranium oxide ('U3O8'), in addition to mineralisation in the pipe cores.
Drilling will resume at Miller when the rig is released from the other VANE
projects..
Big Red Pipe Project
Hole 696-1 was completed to a depth of 1144 feet (349m). The hole was located in
the inferred centre of the pipe based on historic drilling data. The hole
intersected the pipe from the collar to some point above the Coconino Sandstone
formation (above 600 feet (183m)) and from there remained outside the pipe to
its completed depth. The log showed weak anomalous gamma radioactivity.
Favourable alteration was observed in core and drill cuttings in the formation
at and below the expected level of uranium deposition. Both the gamma log and
alteration are highly encouraging indications that the pipe has undergone a
mineralising event and could contain a uranium deposit. Based on results, the
pipe centre is estimated to be located north of hole 696-1.
The rig was moved to the Red Dike project to satisfy the permit agreement work
requirements, as stated above, and a second campaign of drilling on the Big Red
Pipe is now planned.
Red Dike Pipe Project
Drilling on hole 698-1 is in progress. Drilling production on this hole has
been slow due to difficult drilling conditions encountered in the upper part of
the hole. This zone is at present being cased and drilling will resume on
completion.
Matthew Idiens, Director of Corporate Development commented 'The potential
mineralised ore zone of a pipe is, as a result of the high grades found,
relatively small and therefore it can take a few drill holes to intersect the
zone properly. As an example, 3m lbs U3O8 at a grade of 0.7% could be contained
in approximately 255,000 tonnes. Therefore we are encouraged by the results
obtained so far, none of which diminish our view of the favourability or
potential of any of the targets drilled. Since the 1980's, VANE is only the
second company to drill on the south rim for breccia pipes and the third company
to initiate drilling in the breccia pipe district. With this in mind we aim to
use the experience and expertise gained in this region to continue to expedite
the programme further and we are excited about the prospects of additional
drilling on these targets.'
