The Jones showing is located 1.5 kilometres east of the Killarney showing (093M 114) on the west side of the Rocher Deboule Range, 19 kilometres south of New Hazelton.

The showings are hosted in brecciated andesitic volcanic rocks of the Upper Cretaceous Brian Boru Formation (Kasalka Group). Potassium/argon dating of biotite gave a date of 70 million years (Geological Survey of Canada Open File 2322).

Mineralization consists of irregular veinlets of pyrite- magnetite, sphalerite, chalcopyrite and arsenopyrite. The veinlets are hosted in brecciated andesite just east of the contact with the underlying conglomerate member of the older, Lower Cretaceous Red Rose Formation, Skeena Group (Assessment Report 9587).

WORK HISTORY

In 1914, Jones and Bush developed several holes up to 3 metres depth on the Jones showing.

In 1980, 1981, 1984, Asarco Exploration established a grid on the Brian Boru/Killarney occurrence area and collected 156 soil samples. In 1981, IP, VLF-EM and Magnetic surveying was conducted in the Jones and Killarney areas (Assessment Report 9587). Later, mapping and 63 rock and 15 soil samples were collected. In 1985, Asarco, mapped and prospected the Killarney Grid, collecting 74 rock and talus samples; an extension of the soil survey grid was made and 341 samples were collected; silt sampling of creeks resulted in 17 samples.

In 2010, Dunham Gold Corp completed a 495 kilometre airborne geophysical survey on its Porphyry Creek property which covered numerous showings including the Jones occurrence area; the southern limit of the survey is in the Jones area (Assessment Report 31728).
