HIGHLIGHTS FOR HASSAI SOUTH (TARGET 1):
Results for the first 40 holes drilled appear to confirm the 2009
resource Copper intercepts in the pit walls suggest that the
resource may extend beyond the current boundaries New gold and
copper intercepts suggest the presence of scattered higher grade
pockets throughout the orebody The drilling program remains on
track to fully delineate the first two targets by the end of
2011
BEST INTERSECTIONS INCLUDE:
25.7 m at 2.27 g/t Au, 1.46% Cu from 360 m, including 2.0 m at 8.91
g/t Au and 1.30% Cu
11.5 m at 2.05 g/t Au and 3.03% Cu
55.0 m at 0.15 g/t Au and 0.88% Cu from the wall rock
La Mancha is pleased to report that the first round of drill
results for the Hassaï volcanogenic massive sulphide (VMS)
structure appear to confirm the 2009 resource estimate. The Hassaï
South structure was the first of two VMS structures tested by La
Mancha at its Hassaï property in northeastern Sudan in 2007 and
2008. The resulting inferred resource was used in the preparation
of a scoping study released in the fall of 2010.
Moreover, the discovery of new mineralization in the south wall of
the Hassaï South pit, as well as high-grade intercepts at depth,
suggest the potential to improve the resource, both in terms of
size and grade. These preliminary drill results, which are part of
the 100,000-metre VMS drilling program started in October 2010,
brings more confidence with respect to the low geological risk
associated with both converting the resource currently in the
Inferred category to the Measured and Indicated category and
significantly growing the resource.
Dominique Delorme, President and CEO of La Mancha, commented that
"We are pleased with these initial results as they provide more
evidence of our project's strong potential while underscoring the
conservative approach of our positive Preliminary Economic
Assessment ("PEA"). The high-grade drill results obtained recently
from outside the supergene zone indicate that the deposit grades
may be above those used in our PEA. Furthermore, the discovery of
new mineralization in the south wall of the Hassaï South pit,
previously thought to be waste material, is very exciting, as it
suggests that the underground mining assumption used in our PEA may
have been conservative as an eventual resource in Hassaï South's
pit walls could further improve the economics of the project."
Figures 1 and 2 show that mineralization was found outside the main
lenses in the south wall rocks in the western part of the Hassaï
South pit, with a 55-metre intersection at 0.88% Cu.
Moreover, it is important to highlight that the high-grade
deep-hole intercept (2.0 m at 8.90 g/t Au and 1.30% Cu in the D235
at 375m) suggests the presence of locally-enriched gold and copper
zones outside the supergene zone in the primary zone. Furthermore,
the shallow, high-grade intercepts (6.4 m at 1.73 g/t Au and 3.49%
Cu, and 5.0 m at 3.23 g/t Au and 1.30 % Cu) obtained at the lower
limit of the supergene zone reconfirm its existence.
To date, the VMS resource delineated on the Hassaï property
includes an Inferred resource of 51.4MT (20.6MT attributable to La
Mancha) at 1.31 g/t Au and 1.23% Cu. This Inferred resource has
been delineated in the VMS lenses found under the first two of six
visually-identified VMS targets, the Hassaï South and Hadal Awatib
pits. Following the publication of a positive PEA on September 7,
2010, a 12-month, 100,000-metre drilling program was launched with
the intent of upgrading the Inferred resource to the Measured and
Indicated category, increasing the current resource at the first
two targets, and testing the potential of the VMS structure
identified at the third target. As of January 31, a total of 17,837
metres had been drilled, with five rigs in operation. The pace is
expected to accelerate as two more rigs are scheduled to begin
drilling during February 2011. Preliminary drill results for the
Hassaï South target, representing 20 diamond drill holes and 20 RC
precollars, are presented in Table 1 in the appendix.
NEXT STEPS
The VMS exploration program will continue as planned, with results
disclosed as they become available. The Hadal Awatib (target #2)
drilling campaign started in mid-December 2010, and the Hadayamet
(target #3) drilling campaign is scheduled to begin in the coming
weeks. At Hassaï South, exploration of the extensions at depth
which started in January will continue as described in Figure 3.
The Company expects to complete all the drilling in September 2011,
and to use the last months of the year to compile the results and
update the resource model.
Meanwhile, the feasibility study for Hassaï's CIL project is
progressing according to schedule and should be released by the end
of the first quarter.
In accordance with the development plan presented in the PEA in
September 2010, La Mancha intends to develop Hassaï in two phases:
1) the upgrade of the current heap leaching facility to a CIL plant
by 2013 and 2) the construction of a flotation plant to address the
mine's VMS potential from 2015 onwards.
