Feb 12, 2020 (Therese Pettigrew) - The Surprise Lake Occurrence is associated with an esker outwash delta complex. The marl in the vicinity of the swamp area north of the CNR tracks is creamy white, very fine grained and dense. Two holes tested by a soil probe indicated the thickness varied from 90-127 cm (40 to 50 in). Although hard when dry, the marl appears thixotropic in the wet state. A black humus layer up to 15 cm (6 in) thick overlies the marl bed. The upper 25 cm (10 in) of marl are penetrated by tree roots. The lower part of the bed is very clean and white. Where the deposit was penetrated by augering, black silty sand was found underlying the marl bed. No bedding was noted in the central part of the deposit but interbedded sand and peat occur at the edges. Clam and snail shells are present throughout the deposit. Reconnaissance of Surprise Lake revealed that a large portion of the south part of the lake is underlain by marl. Only one area in the northern part of the lake in the large bay on the west side is known to be underlain by marl. Most of the northern part of the lake is underlain by sand and gravelly sand, probably derived from the esker delta complex. (Mason et al., 1985). The Surprise Lake marl deposit occurs as an extensive sediment layer on the bottom of the south part of Surprise Lake and in a low wet area north of the railroad tracks. The marl is composed of a calcium carbonate silt and variable amounts of organics and silica sand. The marl bed varies greatly in thickness, up to 3 m, and typically overlays sand and minor gravel. An organic layer, up to 0.5 m in thickness, locally overlays the marl. Water depth is 1.0 to 3.0 m (Assessment report 52G11NW0002). Assays ranged up to 91.91% CaCO3 and 1.85% MgCO3 (Assessment report 52G11NW0003).
