Résumé

The purpose of this report is to present the status of current geological information generated from the ongoing exploration program on the Poste Lemoyne Extension Property and to provide recommendations for future work. Based on the results of the fieldwork conducted in the summer of 2008, a 93.0-km line grid was cut for geophysics survey. From august to October 2009, the property was the focus of a geological reconnaissance program, of a soil and till sampling survey, and of a trenching program. Following surface work, an 18-hole drilling program was conducted from November 2009 to February 2010. The campaign targeted various anomalies on the new GE and PS grids. More than 50 grab samples collected during the geological reconnaissance program yielded gold grades above 1.0 g/t Au or with anomalous (>1%) base metal values. Based on these results, 5 new anomalous areas were defined. These anomalous outcrops exhibit different geological settings. In the North Contact and Road areas, the best anomalies occur in m-scale silicified and seriticized alteration zones, whereas in the North JUG area, gold occurs in quartz veins several meters wide, at the contact with ultramafic units. In the last two areas, no channel sampling follow-up was conducted. Several mineral showings are also present in the PS Grid and David Grid areas, also occurring in various settings. The main occurrences to date are associated with deformation zones and with rheologic contrasts between felsic intrusives and mafic lavas, but also with a felsic volcanic unit altered to biotite. In parallel with the reconnaissance program, a soil and till sampling program as well as a trenching campaign were completed. The latter was carried out using a small hydraulic excavator over specific geological, geophysical and geochemical anomalies defined during the 2008 and 2009 exploration programs. The 18-hole diamond drilling program totalling 3 331 metres was subsequently completed. The best gold-bearing intersections for the GE grid are: 0.51 gt Au / 53.0 m including 1.00 gt Au / 14.0 m, and 0.41 gt Au / 48.0 m including 2.23 gt Au / 1.0 m and 0.98 gt Au / 10.0 m. On the PS Grid, many anomalous gold intersections have been returned from the drill holes that investigated the EDY showing. High grade intersections obtained on the trench were not repeated in drilling. The best intersections are 1.61 gt Au / 1.0 m in a mylonite zone and 0.29 gt Au / 18 m including 1.61 and 1.10 gt Au / 1.0 m in a new granitic intrusive 130 metres north-east of EDY trench. Also, drill hole PLE10-146 intersected 7.30 gt Au / 1.0 m in a felsic dyke swarn located in the mafic lavas south of the mylonite zone. The results of the 2009 field campaign once again demonstrate the excellent gold potential of the Poste Lemoyne Extension Property. This property, which now extends over more than 70 km E-W by about 3.0 km N-S, has revealed many new potential areas of interest, uncovered either by the geological reconnaissance work or by soil and till sampling surveys. Some of these areas have been further investigated with trenching and drilling, but many of these have a great potential and yet have not been intensively explored to date.
