[{"type":"text","content":"VICTORIA, BC (FSCwire) - Great Thunder Gold Corp. (TSXV: GTG) is pleased to provide a technical overview of its recently optioned Chubb and Bouvier lithium properties located in the Preissac-Lacorne plutonic complex of the Abitibi Greenstone Belt near Val d’Or, Quebec. The Chubb Property The Chubb lithium property is situated within the Preissac-Lacorne plutonic complex of the Abitibi Greenstone Belt – the complex forming one of the best prospective areas for lithium mineralization. The plutonic complex generated the Quebec Lithium mine for which Canada Lithium reported measured and indicated resources of 29.3 Mt grading 1.19% Li2O and 20.9 Mt of inferred resources grading 1.15% Li2O, respectively, according to a technical report by Canada Lithium filed on SEDAR June 8, 2011. The Chubb property lies 32 kilometres north of Val d’Or and consists of 35 contiguous recorded mineral claims with a total area of 1,509 hectares. The property’s geology is dominated by quartz monzodiorite and metasomatized quartz diorite (tonalite). A swarm of spodumene-rich granitic pegmatite dykes intrude fractures and small faults within the plutonic rocks. The pegmatite dykes are 1 to 6 m thick, oriented 345° – 350° and vary in length from 25 to 250 m. They are crudely zoned, some having quartz cores and border zones of aplite. The granitic pegmatites are composed of quartz, albite and/or cleavelandite, K-feldspar, muscovite, with 5 to 25% spodumene. There are three important granitic pegmatite dykes containing spodumene mineralization (Dyke #1, #2 and Main Dyke). Exploration of the Chubb property persists since the early 1950s and has consisted mainly of mapping, trenching, geophysical surveys and diamond drilling. The best drilling intersections were obtained in 1994 by Abitibi Lithium Corp., producing intervals of 3.72 m @1.78 wt. % Li2O, 2.75 m @1.00 wt. % Li2O and 2.38 m @1.25 wt. % Li2O. In 2010, Mineral Hill Industries Ltd. carried out magnetic and IP geophysical surveys, mapping, channel sampling and grab sampling in the area surrounding the three principal spodumene-bearing dykes. The main dyke – which is 300 m long – was shown to have Li2O concentration of 1.00 wt. % (n=41). The Bouvier Property The Bouvier property is located within the Preissac-Lacorne plutonic complex of the Abitibi Greenstone Belt, in the Saint-Mathieu Municipality of Fig...
