Laval, Webb, Gullwing-Tot Lithium Properties

The Laval (1042 hectares), Webb (3579 hectares) and Gullwing-Tot (645 hectares) properties are a lithium-REE exploration opportunity located 25-30 km northeast of Dryden, Ontario.

Grassroots prospecting at the Laval Property in October 2022 has confirmed the presence of pegmatites hosted within metasediments and metavolcanics surrounding the S-type, peraluminous Laval Lake Pluton. Further, metasediments and metavolcanics which pegmatites have intruded into were identified in areas previously mapped as granodiorite, illustrating the opportunity to reinterpret the geology of this underexplored area proximal to the Mavis Lake and Gullwing-Tot pegmatite fields.

Review of historic diamond drill logs by previous operators exploring for other commodities (gold) has confirmed that pegmatite dikes bearing indicator minerals (muscovite, garnet, tourmaline, green mica, greenish feldspar, graphic quartz intergrowth) are widespread throughout this area.

A mica sample (DAJ-86-32) collected as part of an industrial minerals study yielded highly anomalous lithium values of 1421 ppm. Subsequent sampling by the Ontario Geological Survey as part of the reconnaissance study (Operation Treasure Hunt) of peraluminous granites and associated rare-element pegmatites demonstrated modest fractioning of the pegmatites on the Laval Property (mean K/Rb = 102, range = 65-168).

The following recommendation for exploration was provided for this area, arising from the reconnaissance work completed by the Ontario Geological Survey during Operation Treasure Hunt:

Exploration is also warranted across the Minnitaki group in the Eagle Lake-Dryden-Hartman townships area since economically interesting tantalum levels occur in pegmatite dikes. Exploration should initially focus in the exocontact zones around fertile, peraluminous, parent granite masses, such as the Hughes Creek pluton, Zealand stock and Laval Lake pluton and east to northeast of the Ghost Lake batholith.
