GlobeStar's Moblan project covers a group of pegmatite sills and dykes in Archean-age greenstone north of Chibougamau, Quebec, Canada that are characterized by high lithium (Li) values in the mineral, spodumene, a lithium aluminum silicate. The project is divided into two areas, West and East. The Moblan West property hosts the Main Sill pegmatite body.
The Moblan West property comprises 14 contiguous staked claims covering 235 hectares in which GlobeStar earned an interest of 60% from SOQUEM in November 2008, having exceeding the required initial earn-in of US$150,000. A Technical Report prepared for GlobeStar on the Moblan West property was completed in December 2008. It provided Indicated mineral resources for the Main Sill in the Moblan West property of 5.34 million tonnes at an average grade of 1.51% Li2O and a cut-off grade of 0.43% Li2O.. In the higher grade eastern half of the Moblan West property, Indicated mineral resources were estimated at 2.09 million tonnes at an average grade of 1.85% Li2O, and at the same cut-off grade. The Moblan East property is less advanced than Moblan West and is made up of 11 contiguous staked claims covering 163 hectares owned 100% by GlobeStar.
The Moblan property is located 112 kilometers north of Chibougamau and is accessible from Chibougamau via Route du Nord, an all-weather gravel road, to Kilometre 112.5 where a 2-kilometer winter trail runs south to the centre of the Moblan West property. At Kilometre 105 on the Route du Nord, a logging road and winter diamond drill trail provides access to the Moblan East property.
The Moblan property is located in the eastern segment of the Frotet-Evans greenstone belt of Archean age in the Opatica Sub-Province of the Canadian Superior Province. The greenstone belt is enclosed by a granitic-gneissic complex and has itself been intruded by post-tectonic granodiorite to tonalite plutons. The volcanic and sedimentary package is composed of tholeiitic basalts, ferrotholeiites, transitional basaltic flows, calc-alkaline pyroclastic units and sedimentary rocks. Numerous sills and feeder dykes of ultramafic to granophyric composition intruded the sequence and these are very abundant in parts of the belt. Calc-alkaline porphyritic dykes are thought to be the feeders for, or contemporaneous intrusions with, the felsic pyroclastic deposits.
The Frotet anticline divides the greenstone belt into two structural domains. The northern part is characterized by prominent northeast to north-northeast regional schistosity truncated by southeast-trending reverse faults and east-northeast to east-west strike-slip dextral faults. In the southern branch of the anticline, features are oriented east-southeast to southeast where regional-scale reverse faulting interferes with large synclines. Regional metamorphism is greenschist facies in the core of the greenstone belt, increasing to lower amphibolite facies at the margins and around felsic intrusions. The Moblan pegmatite swarm is localized in the nose of the Frotet anticline where confining pressures and readily deformed, impermeable basic volcanic and mafic rocks provided the conditions for containment and crystallisation of the elements, such as lithium, tantalum and niobium that characterize a so-called rare metal pegmatite suite.
A 12-hole diamond drilling program totalling 1,245 meters was completed in December 2007 on the Moblan West part of the property. The principal objective of the drilling program was to test the continuity, geometry and structural control of the pegmatite bodies. Preliminary metallurgical testing by SGS Lakefield produced a spodumene concentrate containing 7.4% Li2O and which exceeds the industry standard specification of 7.25% Li2O for ceramics and glass applications. A lower grade, 5% Li2O, concentrate suitable for the glass industry was also recovered.
The independent Technical Report completed in December 2008 incorporates the results of the 2007 drilling program and metallurgical work, and provides an estimate of mineral resources and a preliminary assessment (scoping study).
The main conclusions of the Technical Report, which focused on the Main Sill pegmatite body, are summarized below:
The preliminary assessment for the Moblan West project, envisioned mining at a rate of 135,000 tonnes per year and the capital cost for mining and processing was estimated at C$22 million. Results of the study determined a net present value of almost C$21 million at a discount rate of 8% per year, for a 10-year operation and an internal rate of return of 26.28%.
As part of the preliminary assessment, an initial analysis was undertaken of potential markets for spodumene, and sodium and potassium feldspar concentrates. Tantalum, rubidium and cesium concentrates, garnet, mica and silica may also be recoverable from the Moblan property, although these were not considered in the preliminary assessment.
The Moblan West pegmatite project is well-placed due to the proximity of a rail line which provides access to potential markets, principally in North America and Europe. The results of the preliminary economic analysis support undertaking a more detailed pre-feasibility study for this deposit, which would include, among other steps:
