The Lower Jack zone was discovered in 1999 during prospecting along a newly constructed logging road in a steep, overburden-covered area. A number of large, lead-zinc bearing, hydrothermally altered, angular tourmalinite and Aldridge Formation fragmental float boulders occur in a 300 by 300 metre area. The float boulders are well mineralized with galena, sphalerite, arsenopyrite and pyrrhotite. The Upper Jack zone (082FNE115) was also discovered by prospecting in the area and is located 2500 metres northwest of the Lower Jack zone. A third discovery, the Sinclair zone, is 2000 metres north-northeast of the Upper Jack zone. The Pakk property includes the Horn, Burn, Pit and Pakk claim groups.
At the Sinclair showing, thin bedded lead-zinc mineralization occurs in a mudstone unit 60 metres thick which has been traced on surface for 600 metres. Chapleau Resources Ltd. completed two short diamond drill-holes on the showing in 1999. The first hole intersected a fault zone and did not find the mineralized zone. The second hole intersected the stratiform sphalerite mineralization 90 metres downdip from the surface showing. The hole cut forty, thin, bedding-parallel bands of disseminated sphalerite and pyrrhotite ranging in thickness from 1 to 10 centimetres. The sulphide-rich bands are scattered throughout the 150-metre section of thin-bedded argillite and silty argillite of the Helikian Aldridge Formation (Purcell Supergroup).
Super Group Holdings Ltd. is directing the exploration and Chapleau Resources Ltd. is performing the work on the property.
