Jeffery Well consists of a single exploration licence application for 82.6km² and lies 43km north of the Cue Township.

The tenement is underlain by stratigraphy belonging to the Meekatharra-Wydgee greenstone belt. Basalts, dolerites and intermediate volcanics predominate with lesser felsic volcanic and volcaniclastic sediments. Minor ultramafic and banded iron formation is intercalated with the mafic sequences. The Chunderloo Shear Zone, locally referred to as the Big Bell Shear Zone, a kilometre-scale, north-easterly trending structure, runs centrally through the tenement. A major NE trending deformation zone, comprising the Cuddingwarra and Weebacarry Shear Zones, marks the eastern contact of the project and the greenstone belt which is intruded by a circular, post-folding, internal granitoid. The Cuddingwarra Shear Zone hosts the Cuddingwarra group of open pit mines developed by Harmony Gold to the south west. Numerous minor cross-cutting faults offset the geology. A variably thick, complex regolith mantles more than 80% of the prospective greenstone stratigraphy, which is exposed mainly in the southwest and southeast parts of the property. The thick regolith has hindered past explorers whom have concentrated efforts on areas of exposed bedrock.

Intensive exploration has concentrated on the exposed bedrock and shallow cover areas in the project; otherwise it remains largely untouched by modern exploration. Several gold-copper soil anomalies, including a 600m long anomaly has been inconclusively drill tested by interface vacuum and RAB drilling. Numerous historical gold workings are known at the “Stringer” prospect, which forms an obvious exploration target. Other targets include jogs and truncations in the stratigraphy in the strain shadow on the western margin of the granitoid body.

Outcrop is sparse over the tenement and limited to mainly Basalt in the Southwestern part of the property and minor occurrences in the southeast corner.  The remainder of the tenement is covered with transported material ranging from 5m to 50m in thickness.
