[{"type":"text","content":"Great Thunder Gold Corp. (TSX.V: GTG) is pleased to announce that it has engaged SGS Metallurgical Laboratory to conduct mineralogical and chemical analyses on lithium-rich rock samples collected from Great Thunder’s Chubb and Bouvier properties located in the Preissac-Lacorne area of the Abitibi Greenstone Belt, Quebec. The analyses will include scanning electron microscopy, particle mineral analysis, electron microprobe and x-ray diffraction to characterize and quantify the spodumene and other lithium-bearing minerals for the purpose of future ore beneficiation. In addition, Mr. Joel Simard, a geophysicist from Quebec, has been hired to undertake in-depth processing and interpretation of data acquired in the 2010 ground-based magnetic and induced polarization surveys. The processing will include 3-D mag and IP inversions that will help define precise future drilling targets. The Chubb Property The Chubb property is located in northern Québec in the Abitibi-East County, Lacorne municipality, NTS map sheet 32C05. The lithium claims are situated within the Preissac-Lacorne plutonic complex of the Abitibi Greenstone Belt. The complex forms one of the best prospective areas for lithium mineralization, including 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 kilometers north of Val d’Or and consists of 35 contiguous recorded mineral claims for a total area of 1,509 hectares or 15.1 square kilometers. The property 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 meters thick, oriented 345° – 350° and vary in length from 25 to 250 meters. 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 ...
