The Finding Jackson occurrence is located just south of Lewis Creek, approximately 26 kilometres northeast of Kimberley. The area is underlain by rocks of the Helikian Fort Steele Formation, Purcell Supergroup, consisting primarily of quartzite and siltstone. Mesoproterozoic gabbro dikes and sills intrude the stratigraphy.

Finding Jackson showings occur along the surface projection of the Lewis Creek Fault. The Lewis Creek Fault was drill-tested in 2007 by Ruby Red Resources; they encountered anomalous gold over a 2-meter interval (Assessment Report 29808). (Refer to Lazy 19, 082GNW059). Surface gold showings occur in north-south trending quartz veins within a multiphase mafic body and in sulphide rich quartz veins within Fort Steele Formation quartzites. Quartz-sulphide-oxide veins hosting principally copper, pyrite, hematite, and magnetite carry gold up to 10.61 grams per tonne gold, 8.8 grams per tonne silver, and 0.051 per cent copper (sample CK11-1001, Assessment Report 32868). The veins are associated with north-south shearing and occur along the projection of the Lewis Creek Fault. Gold up to 5.5 grams per tonne is hosted in crushed and brecciated Fort Steele quartzites and is related to a wider fracture-controlled copper halo (Assessment Report 32868). Large zones of quartz-carbonate-listwanite stockworks are developed along the fault but appear to only host weakly anomalous gold unless narrow sulphide rich veins are sampled.

In 2010 the property was optioned from Spirit Gold Inc (formerly Ruby Red Resources) by PJX Resources who proceeded to fly an airborne mag-em survey over the south-western portion of the Jacleg property. The survey produced a series of magnetic anomalies which appear to be aligned in a northerly trend. Some of these magnetic anomalies were spatially associated with known gold mineralization in outcrop and may be associated with buried Cretaceous felsic intrusions, a feature common in the region. Follow up prospecting by PJX discovered a series of ‘new’ gold showings, some with previously unknown workings, associated with the magnetic anomalies. At the Finding Jackson showing gold up to 10 grams per tonne was returned from magnetite bearing quartz veins near where a gabbro is terminated by a north-northwest trending fault (as reported in Assessment Report 33700).

In 2002, a float sample (JL-02-4) collected in the Finding Jackson vicinity consisted of limonitic and vuggy quartz vein within a gabbro hostrock. The quartz contained medium-grained galena. The sample assayed 21.35 grams per tonne gold, 157.7 grams per tonne silver, 2.69 per cent lead, and 0.098 per cent copper (Assessment Report 26905).

In 2016 to 2019, PJX Resources Inc. conducted geological mapping and rock geochemistry sampling on the Dewdney Trail Property, including the Jackleg area (Assessment Reports 36649, 38859).
