GLOBAL ANNOUNCES HIGH GRADE SILVER INTERCEPTS AT STRIEBORNA
Global Minerals Ltd. has released positive drill results from a six-hole 1,703-metre
surface drilling program on its 100-per-cent-owned Roznava project in eastern
Slovakia.
HIGHLIGHTS OF THE HOLES THAT INTERCEPTED THE STRIEBORNA VEIN
Hole ID From To Length Grade Au Grade Ag Grade Cu Grade Sb
(m) (m) (m) (g/t) (g/t) (%) (%)
GMB-02* 234.70 241.70 7.00 0.147 345.0 1.31 1.01

Notes
* Ag grades top cut to 2,000 grams per tonne (g/t) including one sample
in GMB-02 and two samples in GMB-04.
* Cu and Sb grades top cut to 5 per cent including one sample in GMB-02
and two samples in GMB-04.
Holes GMB-01, GMC-01 and GMC-02 did not hit any mineralization.
True widths are estimated to be 50 per cent to 60 per cent of the
interval lengths
The company believes that this is the first time the Strieborna vein has
been analyzed for gold. The presence of gold may provide an additional
credit if recovered in concentrates and will now be considered in
future economic assessments.
"The drill results are promising and support the current resource model
and respective grades," said William Bond, vice-president, exploration, for Global.
"The drill program was designed to evaluate the upper northeast portion
of the vein where previous drilling was limited. The reported grades
are consistent with previous underground sample data and resource
estimates in the vicinity of the drill holes intersections. We
anticipate that we will continue to add or upgrade our resource base as
drilling continues in this area." This phase of surface drilling has
been completed, and additional drilling will be completed from
underground once access has been re-established later this year.
Permitting is well advanced for the mine dewatering and treatment
facilities. A manager of mining activities and a hydrogeology engineer
have been added to the project team (news release from May 31, 2011). Their
responsibilities will cover all aspects of permitting, inspecting and
re-establishing access to the underground workings.
Global commissioned the compilation of existing regional data which is
now complete. Preliminary results are encouraging, and, as a result, an
additional 120 square kilometres of exploration licences have been applied for.
Initial reconnaissance of newly identified targets will be undertaken
during the summer field season.
A mercury spectrometry survey and CSAMT (resistivity) geophysical survey
have been commissioned to further examine new exploration areas in
close proximity to the Strieborna vein. The data collected will be
used to define and prioritize possible new surface drill targets.
About Strieborna
The Strieborna vein is a high-grade silver-copper-antimony deposit with
a defined resource. The project is part of a historic mining district
near the town of Roznava in eastern Slovakia. The current resource
occurs within a mineralized structure 1.2 kilometres long, 600 metres deep and with an
average thickness of 3.4 metres. The resource has been defined by previous
drilling and a series of four horizontal underground drifts totalling
3,000 metres. The mineralization is open in various directions along the
vein structure. Other similar structures have been identified within
the mining and exploration leases, and these will also be tested for
metal potential in subsequent drill programs.
Besides the upside exploration potential and the high-grade nature of
the polymetallic mineralization, the project has excellent
infrastructure, including sufficient electrical power, railway access,
paved highways and a work force experienced with underground
operations. Underground access is available via old mine workings.
Qualified person
Mr. Bond, MSc, Geol, and vice-president, exploration, for
Global, is the qualified person (QP) under National Instrument 43-101 responsible for the
Strieborna exploration program. He has verified the drill results and
other data disclosed in this news release, including sampling,
analytical and test data. Fieldwork has been conducted under his
supervision. All samples were submitted to ALS Chemex laboratories for
analysis in Rosia, Mont., Romania and Vancouver, Canada. Gold samples
were analyzed by fire assay and atomic absorption spectroscopy with a
30-gram nominal sample weight. Initial silver values were determined by
fire assay with a 30-gram nominal sample weight and gravimetric
finish. Overrange silver, copper and antimony are analyzed by
induction coupled plasma and atomic emission spectroscopy (ICP-AES) using
four-acid digestion methods. Quality control and quality assurance
protocols were incorporated with the submitted samples which included
standards, blanks and duplicate analysis.
We seek Safe Harbor.
