Global Announces High Grade Silver Intercepts at Strieborná
Highlights include 500 g/t Ag, 1.85% Cu and 1.45% Sb over 13 m in hole GMB-04
VANCOUVER,June 13, 2011/CNW/ - Global Minerals Ltd.(CTG : TSX-V)is pleased to announce positive drill results from a six hole 1,703 m surface drilling program on its 100% owned Roznava project in easternSlovakia.

* Ag grades top-cut to 2000 g/t including 1 sample in GMB-02 and 2 samples in GMB-04 * Cu and Sb grades top-cut to 5% including 1 sample in GMB-02 and 2 samples in GMB-04 Holes GMB-01, GMC-01 and GMC-02 did not hit any mineralization True widths are estimated to be 50-60% of the interval lengths |
The Company believes that this is the first time the Strieborná 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, saidWilliam Bond, VP 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 ReleaseMay 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 km² of exploration licenses 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 Strieborná vein. The data collected will be used to define and prioritize possible new surface drill targets. About Strieborná The Strieborná vein is a high-grade silver-copper-antimony deposit with a defined resource. The project is part of an historic mining district near the town of Roznava in eastern Slovakia. The current resource occurs within a mineralized structure 1.2 km long, 600 m deep and an average thickness of 3.4 m. The resource has been defined by previous drilling and a series of four horizontal underground drifts totaling 3,000 m. 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. Global Minerals Ltd. is a Canadian exploration and development company focused on developing its high-grade silver, copper, antimony Strieborná deposit in Slovakia. Global is 35% owned by Esperanza Resources Corp. (EPZ.V) whose principles were previously familiar with the Roznava Project and are now involved in supervising the technical programs and future development. QUALIFIED PERSON: William Bond, M.Sc., Geol. and VP Exploration for Global is the Qualified Person (QP) under NI 43-101 responsible for the Strieborná exploration program. He has verified the drill results and other data disclosed in this news release, including sampling, analytical and test data. Field work has been conducted under his supervision. All samples were submitted to ALS Chemex laboratories for analysis in Rosia Montana, Romaniaand 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. Over range Silver, Copper, and Antimony is analyzed by induction coupled plasma - 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.
