The Jessie showing is adjacent to the Kettle Valley Railway on the north bank of Trout Creek, 350 metres east of Thirsk Siding and 2.5 kilometres east-northeast of the east end of Thirsk Lake.

A steeply dipping quartz vein, striking north-northeast, cuts orthoclase porphyritic granodiorite of the Middle Jurassic Osprey Lake batholith. The vein is 5 to 20 centimetres wide and has been followed along strike for 34 metres and downdip for 23 metres. Some faulting of the vein is evident in underground workings.

Mineralization consists of sphalerite and galena and minor pyrite and chalcopyrite.

A sample of high-grade vein material from the lower of two tunnels assayed 19.2 grams per tonne gold, 24.0 grams per tonne silver, 0.30 per cent copper and 54 per cent zinc (Minister of Mines Annual Report 1928, page 264). A more representative sample from the lower tunnel assayed trace gold, 41.1 grams per tonne silver and 1.8 per cent copper (Minister of Mines Annual Report 1928, page 264).

In 2011, a chip sample (B-01) assayed 0.103 per cent copper and 0.321 per cent zinc over 0.6 metre (Kerr, J.R. (2018-04-04): Technical Report on the Kathleen Mountain Property).

Work History

Two adits, 3 and 24 metres long, were excavated adjacent to and immediately below the railway tracks by E. Hales and D. McDonald in 1928. B.R. Mowry conducted an electromagnetic survey over the deposit in 1990. In 2011, the area was examined and sampled. In 2018, Vizsla Capital Corp. completed a program of 310 line-kilometre airborne geophysical survey on the area as the Kathleen Mountain property.
