The JJ showing is situated approximately 30 kilometres west of Castlegar, north of Highway 3.

Regionally, the property is underlain by Middle Jurassic Nelson intrusions, which are themselves intruded by the Middle Eocene Coryell batholith and numerous tertiary mafic dikes. The Nelson intrusions consist of porphyritic granite, granodiorite, quartz monzonite, monzonite and tonalite with minor diorite. The Coryell intrusions consist of coarse-grained porphyritic syenite and lesser granite, diorite and monzonite.

The JJ showing is hosted by Middle Jurassic pale, equigranular, coarse-grained plutonic rocks of granodiorite-quartz diorite composition. Quartz stockworks, vein breccias, and ladder and sheeted veins occur within a shear zone approximately 25 metres in width. Individual veins exposed on surface range from 0.5 to 30 centimetres in width. The vein stockworks contain pyrite plus or minus traces of arsenopyrite and galena. The shear zone, which is accompanied by quartz-clay-sericite alteration, has been traced or projected in outcrop and float along a strike length of 2 kilometres. Assays from grab samples of quartz veins within the zone ranged up to 19 grams per tonne gold; values in the 2 grams per tonne gold range are common (Technical Report, November 10, 2003 [www.sedar.com]). Coryell age syenite dikes with significant k-feldspar phenocrysts but lacking quartz cut the intrusive and trend 350 to 020 degrees in a north-south oriented fault. Irregularly oriented lamprophyric and basaltic hypabyssal mafic dikes have also been identified.

The JJ gold showing was discovered by Kootenay Gold Corp. in 2003. In 2003, an exploration program found an anomalous float sample yielding 43 grams per tonne gold located approximately 9 kilometres south of JJ Main associated with a gold soil anomaly named Big Sheep (Turner, A. (2008-03-27): Technical Report on 2007 Exploration at the Jumping Josephine Property).

In 2004, Kootenay Gold Inc. conducted geological mapping and petrographic analysis. Quartz±pyrite±arsenopyrite±galena veinlets were observed in northeast-trending shear zones within granodiorite (Assessment Report 27877).

In 2006, Astral Mining Corporation conducted 1330.55 metres of airborne electromagnetic and magnetometer survey (Assessment Report 28477). Astral Mining Corporation conducted a program of soil sampling (551 samples), an airborne electromagnetic and magnetometer survey and 17 trenches, totalling 775 metres, on the area of the JJ Property. Sampling of the trenches yielded values of up to 133.91 grams per tonne gold over 1 metre, although nugget mineralization led to reanalysis and rejection of the samples, while sampling of trench 3 averaged 7.38 grams per tonne gold over 8 metres (Brittliffe, D., Terry, D. (2007-02-28): 43-101 Report on Exploration at the Jumping Josephine Property, Southeastern British Columbia). The highest gold concentrations were observed to occur within 1 to 2 meters of the hanging/footwall contact of the main silicified zone.

In 2007, Astral Mining conducted diamond drilling totalling 6530.56 metres across 58 holes. Significant intercepts include 8 metres of 12.44 grams per tonne gold in drillhole 07JD049 (Assessment Report 29747). In the 2007 exploration program by Astral Mining Corporation, samples from trenches exposing the JJ main quartz stockwork zone were collected for analysis, and a two-phase drilling program was conducted. Of the three trenches dug, only one returned significant gold grades at 0.40 grams per tonne over 3 metres with a maximum of 0.63 grams per tonne over one metre (Turner, A. (2008-03-27): Technical Report on 2007 Exploration at the Jumping Josephine Property). The drilling program successfully traced the mineralized stockwork zone from the surface outcrop along strike for 700 metres to where it diminished at 225 metres depth. In phase one, drilling encountered significant mineralized zones. Highlights of drilling included 42.61 grams per tonne gold over 2 metres in hole 07JD001, 16.91 grams per tonne gold over 1 metre in hole 07JD007, and 16.42 grams per tonne of gold over 5 metres in hole 07JD013 (Turner, A.J. (2008-03-27): Technical Report on 2007 Exploration at the Jumping Josephine Property). In phase two, drilling was conducted to extended exploration of mineralization discovered in phase one. Significant mineralization was intercepted. Highlights of the drilling were 56.4 grams per tonne gold over 1 metre in hole 07JD032, 12.44 grams per tonne gold over 8 metres in hole 07JD048, and 26.9 grams per tonne gold over 3 metres in hole 07JD048 (Turner, A.J. (2008-03-27): Technical Report on 2007 Exploration at the Jumping Josephine Property).

In 2008, Astral Mining Corporation conducted trenching, geochemical sampling, prospecting, 34 diamond drill holes totalling 5074.86 metres and a 53.8 kilometre induced polarization survey. Significant drill results include 17 metres of 1.5 grams per tonne gold in drillhole 08JD077 (Assessment Report 31042).

In 2009, Astral Mining Corporation conducted soil and stream geochemical sampling, trenching and channel sampling; a 2941 line kilometre aerial geophysical survey complimented previously flown areas. Soil gold anomalies were often weak, even over known mineralization, but correlated well with arsenic, suggesting that coincident anomalies are a better indication of buried mineralization on the property (Assessment Report 31673).

In 2010, Astral conducted a drill program of 5,557.7 metres between 36 drill holes on the JJ Main area (Turner, A.J. (2011-06-24): Technical Report on an Initial Resource Estimate for the Jumping Josephine). The results were not reported in the technical report.

In 2011, Astral Mining Corporation released indicated resources of 363,000 tonnes at 2.95 grams per tonne gold and inferred resources of 448,000 tonnes at 2.08 grams per tonne gold, both at a 0.5 gram per tonne cut-off grade (Turner et al 2011).

In 2013, Astral Mining Corporation Ltd. undertook a detailed interpretation of past geophysical survey results, suggesting deep-rooted and extensive structural controls on geophysical anomalies and known mineralization (Assessment Report 33652).

After earning a 100 per cent stake in the Jumping Josephine property in 2014, Orex Minerals Ltd. conducted a prospecting, trenching, and drill program across the property, including work
