The Bank showing is located 1 kilometre southwest of the confluence of Tenas Creek with Birkenhead River (Assessment Report 23595).
Regionally, the property lies in a northwest trending belt of Upper Triassic Cadwallader Group rocks, which represent a northwest trending, northeast dipping, calcalkaline, island arc, volcano- sedimentary assemblage intruded by granodiorite to quartz diorite of the Jurassic to Cretaceous Coast Plutonic Complex. The Cadwallader Group consists of andesitic breccias, tuffs, rhyolites, rhyolitic tuffs and agglomerates with phyllite, sandstone, minor limestone and conglomerates. The Yalakom fault zone is located approximately 50 kilometres to the northeast. The Harrison Lake fault is postulated to pass very close to the showing, to the southwest.
The majority of outcrops in the vicinity of the Bank showing consist of medium to dark grey lithic tuff with minor andesitic flows. Minor limestone was found near the site of some old workings. The dominant fabric strikes north and dips 58 to 83 degrees to the east. The major fracture pattern strikes east and dips 58 to 75 degrees south. A 5 centimetre wide shear was located in one lithic tuff outcrop. Varying degrees of silicification is evident in most outcrops. Weak to moderate argillic alteration is also present. Chloritization is strong at the old workings. At the old workings and 200 metres to the south-southeast, pyrite and chalcopyrite with minor arsenopyrite, sphalerite and galena were observed as disseminations. Malachite is present.
In 1994, the area was explored as a part of the Bank claims by Donegal Developments. Exploration work included prospecting, geological mapping, geochemical and geophysical surveys. The area was explored as the Tex property in 2002 with 243 metres of diamond drilling in four holes on the adjacent Texas occurrence (MINFILE 092JSE002). In 2007 through 2011, Homegold Resources completed various programs of geological mapping, geochemical sampling and prospecting.
Six rock samples were taken in 1994; two from the old workings and four from the outcrop to the southeast. Sample Bank 2 from the old workings yielded 0.13 per cent copper, 0.15 per cent zinc and 1.4 grams per tonne silver. Sample Bank 1, also from the old workings yielded 3.3 grams per tonne silver and 0.84 gram per tonne gold. Sample Bank 4, from the outcrop, yielded 0.66 per cent copper, 22.9 grams per tonne silver and 1.02 grams per tonne gold. Sample Bank 3 yielded 62.0 grams per tonne silver and 4.05 grams per tonne gold. Sample 523316 yielded 0.71 per cent copper, 8.5 grams per tonne silver and 0.62 gram per tonne gold. Sample 523317 yielded 0.52 per cent copper, 19.7 grams per tonne silver and 0.58 gram per tonne gold. Samples Bank 3 and 4 also yielded 0.20 and 0.13 per cent arsenic (Assessment Report 23595).
