Windarra Minerals Ltd. (the "Company") (TSX VENTURE:WRA) -
-Up to 2.29 g/t over 12.4 m in new zone, and 1.03 g/t Au over 20.1 m at KK zone
-Located less than 3 km from Wesdome's Magnacon mill
Windarra Minerals Ltd. is pleased to announce the results of a diamond drill
program conducted between February and April at its 100% owned Mishi Leases
property. The property is located approximately 50 km west of Wawa and is
accessible by an all-weather road leading to Wesdome's Mishi-Magnacon milling
complex, which largely processes ore from Wesdome's nearby Eagle River mine, and
from the Mishi Open Pit, which is less than one km east of the Mishi Leases
property boundary.
The drilling, totaling 3111 meters in 25 holes, intersected bulk tonnage-style
gold mineralization similar to that at the Mishi Pit (see Table I and Figures 1
to 3 for significant intersections). Two of the more significant intercepts are
32.0 m averaging 1.03 g/t Au, which includes 12.4 m at 2.29 g/t Au (hole
M11-13), and 20.1 m averaging 1.03 g/t Au (hole M11-18). These intersections
were from widely separate zones, with the former representing a new discovery,
and the latter from the KK Zone, which has yielded a considerable number of
significant intersections from previous drilling and channel sampling, and has
excellent potential for developing a sizeable tonnage of mineralized material.
Drill targets for the 2011 program were located in four areas within the 3 km
long Mishi Leases property. The targets were based in part on encouraging
results returned from geophysical and soil geochemical surveys completed in late
2010 (see News Release dated Feb. 9, 2011). Other targets were outlined from a
compilation of exploration results, largely from the 1980's and 1990's, in which
approximately 40 holes were drilled across the property. The earlier programs
returned very encouraging results, including drill intercepts and trench channel
samples of both narrower high-grade mineralization and broad lower-grade
"bulk-mineable"-style mineralized material.
The most encouraging results from the 2011 drilling were from holes M11-18 to
25, which targeted mineralization in the KK Zone on the western part of the
property (see Figures 1 and 2). The KK Zone had been drilled previously and this
year's drilling was designed to test continuity of mineralization along trend
and down-dip. All eight holes intersected multiple zones of gold mineralization,
with the most significant intervals being: 1.03 g/t Au over 20.1 m (hole
M11-18), 0.77 g/t Au over 12.0 m (hole M11-20), 0.54 g/t Au over 20.9 m (hole
M11-22), and 0.61 g/t Au over 20.6 m (hole M11-25). The results of drilling at
the KK zone demonstrate that mineralization is continuous across broad widths
and they have confirmed the near surface bulk-tonnage potential of the zone,
which remains open both down-dip and along strike.
Drilling in the central part of the property yielded significant assays in hole
M11-17 (Figure 1), which returned 2.96 g/t Au across 5.8 m from a zone that
correlates well with a previous drill intersection averaging 2.49 g/t Au across
10.4 m 50 m to the northeast. Farther east, hole M11-13 was drilled beneath a
trench across mineralization, intersecting a zone that averaged 1.03 g/t Au over
an impressive 32.0 m and containing a higher grade section that assayed 2.29 g/t
Au over 12.4 m. This new zone remains open in both directions along trend as
well as down-dip.
Gold mineralization on the Mishi Leases is found in stacked, foliation-parallel,
alteration zones of silica and sericite that host centimeter- to decimeter-scale
quartz veins with small amounts of pyrite, pyrrhotite and rare arsenopyrite. The
predominant host rocks are schistose and locally sheared metasedimentary rocks
and mafic to intermediate tuff Rocks are metamorphosed to greenschist facies and
are locally cut by post-mineral diabase dykes.
Future Work
The Company is planning further work at the Mishi Leases property. Detailed
geological mapping and potential stripping and trenching are being considered in
the vicinity of the KK zone, and infill soil geochemical sampling may be
undertaken to help trace known mineralized zones and define new targets.
Following these efforts, the Company intends to conduct further drilling, to
test any new targets and to expand the known zones.
