The Titan workings are located on the "Upper Chum" claims, previously the Titan claims on the west slope of Mt. Welker, east of Fish Creek in southeastern Alaska. The claims were staked in 1917 and were being worked in 1925. Exxon Minerals explored the property in 1983.

Located in the Intermontane Belt, the area, bounded on the west by the Coast Crystalline Complex and on the east by the Bowser Basin, is part of the Stikinia Terrane.

Mineralization is hosted by the Upper Triassic to Lower Jurassic Hazelton Group Unuk River Formation metavolcanics. The Hazelton Group is a northwest trending steeply east dipping belt of folded andesitic lapilli tuffs, flows and breccia containing a thick se- quence of argillite and siltstone infolded along a synclinal axis. The sequence is intruded by the Early Jurassic Texas Creek plutonic suite of dacitic porphyry dykes and sills, Eocene granitic Hyder intrusives and lamprophyre dykes.

Open cuts expose a quartz vein in a northwest trending sheared and altered porphyry dyke. The dyke has been sericitized and sili- cified. The vein strikes 120 to 130 degrees, dips 45 degrees south and has been traced intermittently in outcrop for 230 metres with a vertical extent of 84 metres. At the southeast end of the open cut, 55 metres above this vein, a band of porphyry up to 1.5 metres wide contains pyrite and quartz stringers. These stringers, up to 10 centimetres wide, contain disseminated sphalerite, galena, pyrite and chalcopyrite. Sphalerite is the most abundant with total sulphide content up to 25 per cent.

Hand picked samples from mineralized surface exposures are re- ported to contain high gold and silver values, while underground assays were low. The showings in the Titan adit were resampled in 1983 by Exxon Minerals (results unavailable). A possible extension of the vein occurs 600 metres east of the camp at 1220 metres elevation with minor similar mineralization.
