The J1 occurrence is situated between Keithley, Weaver and Snowshoe creeks, approximately 21 kilometres north of Likely. Access to the J1 property is via the all-weather, two-wheel-drive Keithley Creek logging road from Likely. At the old settlement of Keithley Creek, a logging road on the east side of Keithley Creek leads to the property.

The property is underlain by interbedded quartzite and phyllite of the Hadrynian Ramos succession within the Barkerville terrane. The main regional structure is the Keithley Creek thrust fault. Units dominantly trend northwest, though they might be displaced by northeast-trending faults.

Mineralization occurs as pyrite and pyrrhotite associated with chloritic and graphitic lamellae and shear planes, quartz-carbonate veins, and as disseminations and microfracture fill.

In November 1995, Noble Metal Group Inc. drilled three diamond drill holes totalling 206.43 metres. Several weakly pyritized and pyrrhotized quartz veinlets with trace chalcopyrite were encountered, but base and precious metal values were low overall (Assessment Report 24335).

In June 1996, an induced polarization and resistivity survey was carried out over part of the J1 and NMG claims on behalf of Nobel Metal Group Incorporated. Several anomalous induced polarization zones were delineated, as well as numerous crosscutting faults (Assessment Report 24851).

In June to October 1996, Noble Metal Group Incorporated drilled four diamond drill holes (96-1 to 96-4) totalling 923 metres to test highly anomalous induced polarization values with lower than normal resistivity. All four drillholes intersected variable thicknesses of interbedded quartzites and green to black phyllites intruded by occasional dioritic dikes, quartz feldspar porphyry and altered ultramafic sections. Numerous intersections of weak to strong sulphide enrichment were intersected throughout the drillcore. Sulphides consist of pyrrhotite and pyrite on chloritic and graphitic lamella and shear planes and disseminations. Pyrite-filled microfractures crosscut the quartzites and phyllites in many sections of the core. Sulphides also occur in quartz veins and veinlets. Sections of altered ultramafic rocks were intersected in holes 1 to 4 with thicknesses varying from approximately 0.5 to 7 metres. Anomalous chromium, nickel, strontium and vanadium assay values were present as well as trace to anomalous platinum group elements. The altered ultramafics for the most part have been completely metamorphosed to an apple green, fine-grained matrix with black augen-like ellipsoidal fine-grained black phenocrysts at varying aligned orientations that become mylonatized in parts. A drillcore sample from hole 96-2 analysed 17 grams per tonne gold (Assessment Report 24825).

In 2009, Noble Metal Group Incorporated completed magnetometer and very low-frequency electromagnetic surveys, which found high-amplitude magnetic anomalies and northeast-trending conductors suggestive of faults and coincident with geochemical anomalies (Assessment Report 31109).

In 2011, Noble Metal Group Incorporated collected soil samples extending eastward toward Weaver Creek. Anomalous gold values up to 20 parts per billion were encountered (Assessment Report 32512).

In 2012, Noble Metal Group Incorporated collected 251 soil samples, finding gold anomalies up to 80 parts per billion (Assessment Report 33495).
