Dec 07, 2005 (A Wilson) - Elevated gold values are recovered from carbonatized shists and quartz-carbonate veins. The schist is composed of sheared komatiitic rocks. Several narrow quartz porphyry dikes were observed in the area. The schist has also been described as greenish in colour.

Feb 21, 2008 (D Draper) - Chip sampling by Comstate within a stripped area due east of the occurrence site (exact distance unknown, within 200m) returned an assay of 770ppb Au. (T-2961) PJV hole CP04-01, drilled 400m ENE of occurrence locn, returned 0.535 g/t Au over 1m @ 75.5m downhole. The sample was from a unit of mixed greywacke/argillite and ultramafics with 3% quartz-ankerite veining. (T-5085) Sample 58314, collected in 2004, returned 14.13 g/t Au. The sample site was in the NE corner of claim 3010181, within 50m of original Swanson occurrence. No sample description is provided in the report. (T-5196)
Feb 21, 2008 (A Wilson) - A chip sample taken across 2.7 ft of carbonated schist returned an assay of $3.20 Au in 1938. Grab samples collected by Sylvanite Gold Mines in 1940 returned a best assay of 1.60 dwt over 3 ft. (T-82) The average value of gold in 1938 was $35.20/oz. A value of $3.20 would be equivalent to 0.09 opt Au.
