The Thomlinson Creek copper-molybdenum occurrence is located 11 kilometres east of Mount Thomlinson, about 42 kilometres north-northeast of Hazelton.

The claims are underlain by carbonaceous sandstone, siltstone, shale and conglomerate of the Middle Jurassic to Lower Cretaceous Bowser Lake Group intruded by a small multi-phase intrusive body of the Eocene Babine Intrusions which include granodiorite, quartz monzonite and biotite hornblende quartz diorite.

The intrusive body is 600 metres wide and at least 4 kilometres long. It is extensively fractured and mineralized with pyrrhotite, pyrite and chalcopyrite as well as less common molybdenite and scheelite. Mineralization also extends into the hornfels which is up to 300 metres in width adjacent to the intrusion. Biotite feldspar porphyry and quartz porphyry dike rocks intrude the hornfels and quartz diorite. Silicification, together with later kaolinitic, chloritic and sericitic alteration, are characteristic of the property.

In 1970, the Thomlinson Creek property was originally staked by Granby Mining Corporation to cover a prominent Geological Survey of Canada airborne magnetic anomaly related to a Babine intrusive body. Ground soil geochemical, induced polarization (IP) and magnetic surveys were underundertaken by Granby and by Noranda Exploration Company who optioned the property from Granby. This work defined a large chargeability anomaly with coincident copper and molybdenum soil anomalies. Prospecting located low to moderate grade copper and molybdenum mineralization in outcrop and float.

In 1980-81, Noranda completed 1024 metres of diamond drilling in ten holes with discouraging results. The claims were subsequently allowed to lapse.

In 2004, the property was restaked by R.H. McMillan and R.R. Blusson and then optioned to Dentonia Resources Ltd. In 2005, work done by Dentonia on the Thomlinson Creek property focussed on prospecting, silt geochemical sampling and evaluation of potential drill sites. A total of 12 rock samples were collected, all of which were from the area north of Thomlinson Creek. A total of 30 silt samples were collected from creeks draining into Thomlinson Creek. In addition, Dentonia engaged Graff Engineering of Smithers, British Columbia to conduct an evaluation of proposed drill trails and drill sites north and south of Thomlinson Creek.

In October 2006, Dentonia drilled three NQ diamond-drill holes totalling 830.9 metres. Two of these holes intersected low grade copper and molybdenum mineralization. Hole TC06-3 was the best hole and averaged 0.022 per cent molybdenum, 0.09 per cent copper and 0.013 per cent tungsten over 250 metres. The best intersection within this interval was 2 metres averaging 0.146 per cent molybdenum, 0.114 per cent copper and 0.038 per cent tungsten. Mineralization in hole 3 is comprised of disseminated and fracture-controlled molybdenite and chalcopyrite in a variably altered granodiorite intrusion.
