Dec 07, 2005 (B Schnieders) - Schnieders et al., (1996) describes the Sunrise vein as a 18 m wide vein in the Highway 17 roadcut. The vein strikes northeast and dips vertically. The vein contains barite and fluorite, and very little amethys. Up to 23.11 CaF2 over 3 m.
Dec 07, 2005 (R Degagne) - The Sunrise Vein is 18 m wide in the Highway 17 roadcut. It strikes approximately northeast-southwest and dips vertically with very sharp contacts. Detailed mapping has not been successful in tracing this fluorite-bearing zone along strike. To the northeast it is covered by alder swamp and glacial till. To the southwest there is no outcrop along the strike of the vein. The Midday vein is about 5.8 m wide, strikes 74 degrees and dips 68 degrees northwest. It is located to the west of the Sunrise vein, within the same roadcut. It runs into a swampy area to the west and pinches out 61 m east of the road-cut. It has a possible maximum strike length of 305 m. (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay).

Apr 29, 2019 (Therese Pettigrew) - The granite is a fine- to medium-grained pink rock which ranges in composition from a granite to a granodiorite. The granite is cut by numerous narrow pegmatite veins comprised of quartz and coarse-grained feldspar. The veins vary in width from a few inches to 2-3 feet and strike N70E across the property. There are numerous fluorite occurrences on the property. The majority of these are found on surfaces of joint planes, as films of purple fluorite cubes. Three major fluorite-bearing veins and a few minor ones have been located. They contain large granitic fragments cemented together by quartz, barite, and fluorite. The quartz is usually a milky variety although some cavities are lined with amethyst crystals. The breccia fragments contain epidote, giving the breccia zones a greenish-yellow colouration on fresh surfaces (Assessment file 42D13NE0008).

Dec 07, 2005 (R Degagne) - Both the Sunrise Vein and Midday Vein contain barite and fluorite, but very little amethyst. Brecciation is not as apparent as in the Sunset Vein although epidotization is very strong, giving the zones a greenish-yellow colour on fresh surfaces. The fluorite and barite occur as narrow veinlets along irregular fractures within these zones. Assay values are erratic due to the irregular nature of the mineralization. (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay) CHEMICAL ANALYSES: One section assayed up to 23.11% CaF2 over 3 m across the veins. (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay) The following assays were obtained by Asarco on the Sunrise Vein: Sample No. 7136: Assay Width: 3 m (10') 0.31% CaF2, Location: N side highway. Sample No. 7137: Assay Width: 3 m (10') <0.10% CaF2, Location: N side highway. Sample No. 7138: Assay Width: 3 m (10') <0.10% CaF2, Location: N side highway. Sample No. 7139: Assay Width: 3 m (10') 7.03% CaF2, Location: N side highway. Sample No. 7140: Assay Width: 3 m (10') 0.99% CaF2, Location: N side highway. Sample No. 7141: Assay Width: 3 m (10') 23.11% CaF2, Location: N side highway. Sample No. 7145: Assay Width: 3 m (10') 3.55% CaF2, Location: S side highway. Sample No. 7146: Assay Width: 3 m (10') 0.97 % CaF2, Location: S side highway. Sample No. 7147: Assay Width: 3 m (10') 5.00% CaF2, Location: S side highway. Sample No. 7148: Assay Width: 3 m (10') 0.32% CaF2, Location: S side highway. Sample No. 7149: Assay Width: 3 m (10') 10.64% CaF2, Location: S side highway. Sample No. 7150: Assay Width: 3 m (10') 16.13% CaF2, Location: S side highway. (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay). The following assays were obtained by Asarco on the Midday Vein: Sample No. Sample Width % CaF2 7135 5.8 m (19') 10.44 7143 3 m (10') 13.54 7144 2.7 m ( 9') 5.32 (Resident Geologist's Files, Schreiber-Hemlo District, Thunder Bay).

Geologist: R Degagne
Notes: Visited in July, 1991 by P. Hinz | R. M. Landry (OGS OFR 5889, 1994). COMMENTS/RECOMMENDATIONS: The Sunrise and Sunset Veins are narrow and contain erratic fluorite values. For these reasons, the veins will probably only be of interest to rock hounds and mineral collectors.
