The Lizard showing is located on Birkenhead Creek west of the Mount Currie-D'Arcy road, 18 kilometres north-northeast of Pemberton.

The showing was first staked in 1982 as the Lizard claims. In 1990, the showing was restaked as the Later claims. Earlier work not recorded is evidenced on the property by an abandoned drillhole and drill core, and trenches.

The Lizard skarn showing occurs within a region underlain mainly by plutonic rocks of the Jurassic to Cretaceous Coast Plutonic Complex, which have intruded sedimentary and volcanic rocks of the Upper Triassic Cadwallader Group.

The showing occurs where a small plug of quartz diorite of probable Cretaceous age has intruded limestone of the Hurley Formation, Cadwallader Group. A sequence of alternating mafic volcanic tuffs, massive green andesite, limy volcanic sediments, large greenish calcsilicate beds, banded creamy white limestones and metamorphic equivalents comprise hostrocks of the Lizard showing. The hostrocks strike dominantly north with shallow (10 to 45 degrees) dips to the east.

The Lizard showing consists of several zones of skarn alteration. Two skarn mineral assemblages occur: i) a high grade garnet-diopside-epidote assemblage and ii) a lower grade tremolite- wollastonite-calcite assemblage. Scheelite, molybdenite and minor powellite are associated with the first assemblage. Wallrock alteration of the quartz diorite consists of a zone of silicification next to the skarn and potassium feldspar-quartz, quartz-sericite- pyrite and chlorite-epidote moving away from the skarn. The main skarn zone is up to 20 metres thick. A grab sample taken in 1981 from this zone contained 5.75 per cent tungsten trioxide (Assessment Report 10036).
