12/18/2020 (T Pettigrew) - The fluorite mineralization occurs along with barite and amethyst in veins and vuggy breccia zones that have been traced in low outcrops of blocky medium grained granite for approximately 150 m along Lakeshore Road. Fluorite cubes vary from less than 1 mm to 2 mm with numerous cubes lining small vugs that are less than 5 cm in length. The colour varies from very dark to medium purple. Some crystals of fluorite are glassy in appearance. Barite crystals occur as small cream to pink coloured blades up to 2 cm in length. Some skeletal barite crystals appear within a fluorite groundmass. Quartz varies in colour from clear through white, yellow and purple (S. O’Brien and M. O’Brien personal communication, 2020).
