The Lilypad Lakes occurrences are hosted within numerous pegmatite dikes ranging from several centimeters to tens of metres wide (Taylor et al., 2005). The majority of the dikes are reported to strike in an approximately east-west direction (i.e., 240 to 270). However, numerous dikes oriented in an approximately north-south direction are also present. Diamond drilling information indicates that the dikes are also typically continuous to a depth of at least 100m. A number of types of pegmatite dikes were identified by Breaks and Tindle (2004). These deposits belong to the rare-element class of the LCT (lithium-cesium-tantalum) geochemical family, and include albite-type, albite-spodumene type, and complex-type (spodumene and elbaite-subtypes) pegmatites. Details regarding the specific characteristics of the six occurrences/deposits listed above are provided below. Taylor et al. (2005) recognize evidence of two principal regional deformation events in the vicinity of these deposits. Both events have affected the pegmatite dikes and host rocks. The earliest deformation event is characterized by a strong to intense penetrative to locally-spaced cleavage in the metasedimentary and metavolcanic rocks. This fabric approximately parallels stratigraphy in the supracrustal rocks. This fabric is also weakly developed in the more competent pegmatite dikes, and has been noted in the northern portions of the Kawitos Lake batholith. This fabric is likely to have been related to a regional N-S compressional event, and is axial planar to isoclinal folds. A second later strain event is represented by crenulation folds that overprint the earlier fabric. With the esceprion of the Spodumene dike, most pegmatites show little evidence of having been impacted by the second deformation event. These deposits are likely to be genetically related to the Kawitos Lake batholith, which has been identified by Breaks and Tindle (2004) as a potential fertile S-type granite pluton similar to others that are located near the Uchi-English River Subprovince boundary.
