The Treaty East occurrence area is underlain by massive green and grey andesitic to dacitic tuff, lapilli tuff, tuff breccia and minor flows of the Lower Jurassic Betty Creek Formation, Hazelton Group (Open File 1988-4). The beginning of a large gossanous area, known as the Treaty Gossan (104B 078), occurs within a few hundred metres to the southwest of the occurrence.

A grab sample of andesite containing 10 per cent disseminated pyrite and minor quartz veinlets assayed 2.36 grams per tonne gold and 3.3 grams per tonne silver (Assessment Report 16841). The veinlets are up to 1 millimetre wide and have no visible sulphides. The sample was taken from the dump pile of an old trench.

In 1984 Teuton Resources Corp. carried out prospecting in the region. During 1985 and 1986, Teuton Resources Corp. continued exploring the Treaty area with programs consisting of mapping, prospecting and silt sampling. In 1987 persistence was rewarded with the discovery of the Konkin zone (104B 171) on the West Nunatak. This discovery enabled Teuton to carry out blast trenching, rock sampling, grid-controlled soil sampling and diamond drilling, on the West Nunatak, during 1987 and 1988.

In 1989 the property was optioned by Tantalus Resources. From 1989 to 1992 Tantalus carried out mapping, trenching, diamond drilling, sampling and geophysics on the West Nunatak, Treaty Nunatak and Orpiment zones. These efforts culminated in the discovery of the AW-Ridge and Goat Trail zones (104B 172) on the West Nunatak and the Mama Susu zone (104B 370-375) on the GR-2 claims. Between 1987 and 1992 a total of 1437 m were drilled in 18 diamond drill holes on the Konkin, AW, Goat Trail and GR-2 zones. In 1993 the Eureka zone was discovered on the Treaty Nunatak.

Prime Resources Group Inc. optioned the Treaty Creek property in June, 1994 and completed a two-stage program of 15,000 and 1:2,500 scale geological mapping, 90 metres of blast trenching in 11 trenches and 8 diamond drill holes totalling 866.42 metres.

Drilling at Bonsai (104B 383) in 2003 intersected significant low-grade gold/silver mineralization in pyritic rhyolite breccia, beneath the main gossan outcrop. The mineralized zone remained open at depth and to the south providing an excellent target for future exploration. One additional hole was added in 2004. This hole was located 69 meters south (along strike) from drill hole BZ 03-08.

Heritage Explorations Ltd., becoming active in the Treaty Creak area in 2001, became the operating company to explore a 2200-unit claim consolidation in the Iskut district. St. Andrew Goldfields Ltd. and Zebrex Holdings Inc. held a controlling interest in Heritage. The property largely surrounds the Eskay Creek holdings of Barrick Gold Corp. and covers favourable folded stratigraphy from the McKay syncline eastward to the McTag anticlinorium, including the Treaty Creek and Bonsai prospects optioned from Teuton Resources Corp. Heritage undertook an ambitious digital compilation to build a comprehensive topographic, geological, geochemical and geophysical model to explore for Eskay Creek-type precious metal mineralization.

In 2003, Heritage completed three drill holes on the Bonsai prospect (104B 383) optioned from Teuton Resources Corp. and were active on other parts of their large property holdings.

In 2004, Heritage Explorations Ltd. continued exploration of its extensive mineral claim holdings surrounding the Eskay Creek mine with a large geophysical survey and two drill holes (674.5 metres). One of the drill holes was located about 600 metres south of the Treaty East showing and about 1 kilometre east of Treaty Gossan (104B 078). It explored a porphyry system but did not encounter significant mineralization. The other drill hole was on the Bonsai prospect.

In 2020, Tudor Gold Corp. completed 52 diamond drill holes, totalling 45 517 metres, on the Goldstorm (MINFILE 104B 704) and Perfect Storm zones of the Treaty Creek Gold property.
