Access Description: Jessie Lake is located 80 m east of a point on Hwy 599 approximately 7 km south of the Sturgeon Rapids bridge. A short (3 chain) portage east from Hwy. 599 leads to an arm of the lake. The showing is located 2.4 km south of the portage.
1946: A quartz vein was found by prospectors working for Northern Canada Gold Mines on the shoreline of Don Dick Lake, now called Jessie Lake. 1987: Prospector A. Best cleaned out the old trenches and sampled the showing. 1989: Sometime after staking of the claims in 1989, prospectors S.C. Johnson, S. Johnson and W.C. Read examined and sampled the Jessie Lake property. 2009: Aur Lake Exploration carried out prospecting and sampling. 2014: Tasca Resources carried out prospecting, mapping, and sampling.

04/14/2020 (T Pettigrew) - Metavolcanics are predominant in the area of the Fourbay claims but greywackes and siltstones are also common. Country rock units generally strike at 85-95°. Mafic pillows and flows are very common in the Jessie Lake area (Assessment report 20000014549).

01/27/2000 (R Tuomi) - The showing occurs in a sequence of metabasalts which trend from east to southeast and dip to the south. A quartz-carbonate vein is hosted in a mineralized sericite-biotite shear zone which strikes east. Very little of the vein is exposed in the lake shore. The vein is exposed for 4.9 m on a small shoreline outcrop surrounded by water and swamp. A sample of the vein taken across 3.05 m assayed 0.50 ounce gold per ton.
04/14/2020 (T Pettigrew) - Samples collected in 1989 from the historic pit returned assays ranging from 0.055 oz/t Au (1.89 g/t Au) up to 0.22 opt Au (7.5 g/t Au) (Assessment report 52J02SW0001). The historic pit shows the shear feature, which is roughly 2 m thick, strikes 120 degrees with a vertical dip, is strongly silicified throughout, and carries about 1% fine-medium grained pyrite. A channel sample taken in 2014 returned 2.86 g/t Au over 1.9 m, and a grab sample returned 1.67 g/t Au (Assessment report 20000014549).
