McVicar Lake Area
The McVicar Lake Property is located in the Patricia Mining Division approximately 370 km north-northwest of Thunder Bay, 150 km east of Red Lake and 80 km west of Pickle Lake, Ontario.
- The Bear Head Fault Zone is a significant crustal scale structure that has localized gold mineralization in the McVicar Lake Property and extends southeast 30 km where it is closely associated with the Golden Patricia Mine (past producer).
- The Golden Patricia mine contained 0.87 million tonnes grading 19.9 g/t Au (0.58 oz/T Au, and is in a similar structural setting as the lower McVicar Lake area (Chellow Vein). The shear-hosted quartz vein deposit model would be applicable.
- Surface channel sampling of the Chellow Vein indicated high grade gold values in the western trenches resulting in weighted average grades (uncut) of 85.61 g/t Au over 30 metre length (Trench 1), and 85.82 g/t Au over 10 metre length (Trench 2). (an approximate 1 m sample width is estimated)
- Five drill holes intersected the Chellow Vein up to a depth of 150 m, and contained anomalous gold values; the vein is primarily shear-hosted and does not increase from the average width of 20 cm.
- The lack of gold mineralization in drill holes was considered to be likely due to the nugget effect commonly encountered in quartz vein hosted deposits (Waldie, 1993); thin wall BQ drill holes were used.
- There is excellent continuity of the Chellow Vein and structure along strike and down- dip. Within the immediate area of the Chellow Vein are altered shear zones contain quartz with significant gold values on surface. The the pinch and swell nature of the quartz vein may indicate a plunging system.
