1940-41: 3 pegmatic dykes identified by V.K. Prest while mapping. 1956: Standard Lithium Corporation Ltd. - staked claims, drilled 12 ddh totalling 968 m, trenching and channel sampling undertaken. 1962: Robert Campbell acquired the property and drilled 4 ddh totalling 141 m. 1979-82: The Tantalum Mining Corp. of Canada Ltd. (Tanco) – performed lithogeochemistry, e.m., mag., and 52 ddh totalling 5367 m. At least 11 separate anomalies were outlined, with subsequent detailed mapping of several of these. Tanco let the claims lapse in 1985. 1986: Gold Fields Canadian Mining Ltd. – staked the claims and undertook prospecting, channel sampling, mapping, biogeochemcal sampling which assayed for arsenic, assay previously drilled core (1545 samples from 27 drill holes). Airborne magnetic and EM surveys were flown over the west half of the property. No new DDH were drilled by Gold Fields. 1988: All leased claims were cancelled. 1994: Placer Dome Canada Ltd. staked a large series of contiguous claim blocks over the area. 1999-2001: Avalon Ventures staked claims and carried out an exploration program consisting of geophysical surveys (gravity and magnetic), prospecting, geological mapping, a bedrock lithogeochemical survey, diamond drilling and assaying. 1 DDH was drilled on the Spodumene dyke, totalling 115 m. 2000-2001: Joint venture between Avalon and Global Canada. JV terminated following the 2001 program. The project has been inactive since 2001 awaiting a recovery in tantalum prices or new demand for cesium minerals. 2009: Avalon Ventures changed name to Avalon Rare Metals.

Sep 29, 2006 (Mark Puumala) - 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.

Oct 24, 2011 (Mark Puumala) - The spodumene dike occurrence is described by Rees (2001) as a series of east-west trending dikes and stringers extending over a strike length of approximately 240 m. Most of the dikes range in width from 1.5 to 7.5 m and strike parallel to stratigraphy, with evidence of folding and structural modification. The pegmatites are described by Wallace (1978) as intruding a mafic metavolcanic dominated sequence. Breaks and Tindle (2004) describe the dikes as crudely zoned albite-spodumene-type pegmatites composed of muscovite-green spodumene-potassium feldspar-quartz-albite pegmatite and sodic aplite assemblages. Accessory minerals include red-brown garnet, blue apatite, black tourmaline and oxide minerals. Wallace (1978) reported that grab samples collected from this occurrence assayed up to 4.07% LiO2 and that a diamond drill intersection of 10.4 m contained 1.07% LiO2. Rees (2001) reported Ta2O5, Rb2O and Cs2O values of up to 0.014%, 0.306% and 0.038% respectively from samples of drill core collected by Avalon Ventures in 2000. The relatively low Ta, Rb and Cs values are interpreted by Breaks and Tindle (2004) to indicate a relatively primitive geochemical signature. These dikes are also indicated by Rees (2001) to have undergone more deformation than most pegmatites on the property. This observation, combined with the less evolved geochemical signature is consistent with an earlier time of emplacement than for the other mineralized pegmatite occurrences in this area.
Aug 05, 2014 (Therese Pettigrew) - Avalon drilled a single hole (LSP00-06) into the Spodumene Dyke to test the vertical extent of dykes previously mapped by Standard Lithium. They found four separate dykes ranging from 1.15 -7.4 m core lengths (<1-6 m true thickness). The dykes are pink-orange in colour, generally highly albitic with local coarse partially assimilated orange K-feldspark. Fine to coarse green spodumene aggregates occur locally. Albite is generally aplitic with local sections of coarser grained cleavelandite. Generally, tantalum values were negligible and cesium and rubidium values were low, although there was a 2.1 m interval of 0.014% Ta2O5. Avalon reported 0.003% Ta2O5, 0.005% Cs2O and 0.058% Rb2O over 7.4 m, from 65.7-73.1 m.
