Point Location Description: Trench on north side of Goudreau Road on claim SSM4101
Location Method: Based on Assessment
Access Description: Access to the area is via an 18 km long gravel road (new Goudreau Road) that exits off of the Dubreuilville road (highway 519) in northern Finan Township. From the intersection of the old and new Goudreau Roads, the occurrence is located approximately 1 km east. A bush road leads to a large stripped area on the lake shore.
1997-2000: Patricia Mining Corp. - trenching, stripping, sampling, mapping.

Dec 07, 2005 (A Wilson) - The showing straddles the boundaries between the Northern and Southern Domains of the Goudreau Lake Deformation Zone. The GLDZ is up to 4.5 km in width and strikes in a gentle sigmoid-form for at least 30 km, subparallel to the stratigraphy and the regional foliation. In the immediate Goudreau-Lochalsh area, the GLDZ is coincident with a major contact between Cycle 2 and Cycle 3 volcanics. There is a strong structural control of the gold-bearing quartz veins systems within each of the 070-075 striking high-strain zones within the deformation zone. The deposit is hosted by the same shear zone hosting the Magino Deposit. The Southern Domain is composed on an 70 degree striking, ductile-brittle zone of subparallel, dextral oblique-slip, high strain zones developed within strongly altered and deformed felsic to intermediate metavolcanic rocks. The southern domain is approximately 8 km long by 2 km wide.

Dec 07, 2005 (A Wilson) - A grab sample from the vicinity of the Hilltop Trench returned an assay of 1.77g/t Au. Repeat analyses of the same sample returned 1.47 g/t Au and 1.54 g/t Au. Grab amples of quartz veins collected from within the porphyry in 1997 returned values up to 16.6 g/t Au.
