High-grade graphite mineralization
The Lac Guinécourt graphite property consists of 74 map-designated mining claims covering a total of 4,012 hectares and is held 100% by Focus Graphite.
The property, acquired in August 2011, is located in the South Manicouagan Reservoir area of northeastern Quebec, 17 kilometres to the south of Mason Graphite’s Lac Guéret graphite deposit which hosts National Instrument (NI) 43-101 compliant Measured and Indicated mineral resources of 7.6 Mt grading 20.40% Cgr (Source: Roche, 2012: Technical Report on the Lac Guéret Graphite Project; available at www.sedar.com under Mason Graphite Inc.).
Focus announced on May 22, 2013 that the final assay results from the summer 2012 reconnaissance exploration program at Lac Guinécourt returned high-grade graphite mineralization. A total of 32 grab samples were collected from historical and new graphite-bearing outcrops related to the Graphi-Centre showing area. Twenty-one of the samples returned high-grade graphitic carbon (defined as greater than 5% Cgr), with assays ranging from 6.36 per cent to a high of 45.90 per cent Cgr.
The Lac Guinécourt property is located in the Grenville geological Province. Metamorphism associated with the Grenvillian orogeny has resulted in the formation of high-grade concentrations of graphite dominated by value-enhanced large flakes. Fine to coarse graphite flakes and associated sulphides make up 10 per cent to 40 per cent of the rocks, with up to 40 per cent in strongly mineralized zones.
The portion of the property surveyed in 2012 holds the historical Graphi-Centre graphite showing discovered by SOQUEM Inc. and Quinto Technology Inc. (now Cliffs Natural Resources) in 2002 while exploring the geological corridor hosting the Lac Guéret deposit.
Results of an electromagnetic (HLEM) ground geophysical survey carried out in November 2012 over the central part of the Lac Guinécourt property in the Graphi-Centre showing area outlined the presence of nine electromagnetic conductors. This was followed up in July 2013 with a comprehensive exploration program over the best HLEM anomalies delineated from the ground survey, in order to delineate the thickness of the two-km long conductor associated with the historical Graphi-Centre showing.
