The Tenas Creek showing is located on Tenas Creek, approximately 1.5 kilometres west of its junction with the Birkenhead River.

The area is underlain by north striking, steeply dipping Upper Triassic Pioneer Formation (Cadwallader Group) andesites, volcanic breccia, argillite, pyritic quartzite, rhyolites and limestone. The Jurassic to Tertiary Coast Plutonic Complex (granodiorites) intrudes the volcanic package to the west.

Highly gossanous andesites and rhyolites are exposed which show argillic and/or propylitic alteration and contain up to 15 per cent pyrite. A blasted pit on the south side of Tenas Creek revealed minor sphalerite and chalcopyrite in a layered chlorite and epidote rich skarn zone. North of the creek an adit was driven to explore this mineralization.

In 1994, the area was explored as part of the Bank claims of 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.
