Great Basin Gold Continues to Encounter Bonanza Gold Grades at Hollister Propertyadmin
Mining and Exploration company Great Basin Gold Ltd. announces further high-grade exploration drilling results at its Hollister property in Nevada for the quarter ending March 31, 2009. An exceptional result was achieved with underground borehole HDB-274 which intersected 50.11 oz per short ton (“opt”) over 0.7 ft (1,718 g/t Au over 0.23 m) on the western strike extension of the Central Clementine vein. This is 1 of 25 vein intersections during the quarter in excess of 1 opt Au (34.28 g/t Au).
During the quarter, underground evaluation and exploration drilling for other mineralised structures totaled 13,503 ft (4,092 m). Surface drilling totaled 1,449 ft (439 m). The programs continue to encounter high-grade intersections on the Clementine and Gwenivere vein systems (see below), disseminated mineralisation in the overlying Tertiary volcanics, as well as further encouraging intersections from the Hatter Graben Veins to the east of the Hollister development. Geological modeling and mineral resource estimation of these mineral systems is currently underway.
The underground drilling is providing more information about the strike (3,000 ft/ 980 m) and vertical (1,300 ft/ 396 m) continuity of the vein systems. The Hollister mineral system currently comprises 24 discrete east-west striking subvertical veins, which constitute the Clementine and Gwenivere groups. The system is still open along strike, at depth, and in areas up to and above the Ordovician/Tertiary Unconformity. Twenty-six (26) underground boreholes were completed, of which fifteen (15) were for exploration, seven (7) targeted the Gwenivere system and four (4) tested the Clementine system.
Recent results from underground exploration, underground delineation and surface drilling are summarised below. A complete tabulation of the Hollister drilling results is available on the Great Basin Gold website www.grtbasin.com.
