In 1998, Log House Construction completed Magnetometer and VLF surveys in the area and reported bedrock assays up to 13.84% and 16.65% Cu. In 2002, Log House Construction (report of work 475608) reported the results of prospecting and soil and rock sampling. A grab sample from the southeast corner of the property returned anomalous Cu (901 ppm) and Au (351.8 ppb).  In 2006, Log House Construction (report of work 476171) reported the results of prospecting: rock samples yielding up to 3657 ppm Cu and soil samples up to 4317 ppm Cu, 1273 ppm Pb, and 2371 ppm Zn. One soil sample returned > 1% Cu. Similar results were reported in 2007 and 2008 (reports of work 476467, 476665, 476666). The most impressive rock assay from the area (reported in 476666) returned 5.3% Cu, 8.9 g/t Ag, whereas another returned 2032 ppm Zn and 865 ppm Ni.

Mineralization consists of native copper occurring in tiny fractures and as disseminations in middle- Ordovician basalt. Immediately to the north, the basalts are overlain by unmineralized Silurian carbonate and clastic sedimentary rocks. However further north, Carboniferous clastic sedimentary rocks are disconformable on the Silurian sequence. It is likely that these Carboniferous rocks were, at one time, unconformable on the basalts hosting the native Cu but were subsequently eroded. It is postulated that the native Cu mineralization is related to oxidation-reduction reactions typical in sediment hosted Cu deposits, such as those hosted by Carboniferous rocks in southern New Brunswick.
