The Tiger claim was Crown-granted in 1893 and considerable work, including hundreds of metres of underground exploration, was done before 1912. A small shipment of ore (22 tonnes) was made from the claim by T.B. Hansen in 1928 and 5785 grams of silver, 31 grams of gold, 4211 kilograms of lead and 2335 kilograms of zinc were recovered. There is no record of other work on the claim. The old workings are presently obscured by undergrowth. A diagram of the workings can be seen in Figure 30, Bulletin 53 (page 113).

Rocks on the claims are grey knotted schist, with narrow interlayers of fine-grained grey limestone, of the Mississippian to Lower Permian Milford Group. A relatively thick layer of limestone continues northward from the Star property (082FNE026), and thin disontinuous layers found east of it contain the Tiger mineralization. The rocks dip to the west at moderate angles.

The mineralization is associated with two small faults striking northwest and dipping 60 to 70 degrees to the southwest. Veins along the fault contain galena, sphalerite, pyrite and minor chalcopyrite associated with quartz and siderite. Rusty-weathering siderite extends irregularly out from the veins into the limestone and locally carries sulphides. The veins and rusty siderite together form mineralized zones up to 1.2 metres thick. The zone in No. 1 adit is 6 metres long and the one near No. 3 adit is 30 metres long. Lenses with appreciable sulphides are generally less than 60 centimetres thick and follow the veins.
