The Eagle occurrence is located on the west side of Lillooet Lake to the southeast of Mount Currie and approximately 250 metres north- north west of the Lake Adit (MINFILE 092JSE009) occurrence. The Lake Adit and Eagle occurrences were historically worked as one property, referred to as the Lake Adit property.
Regionally, the area is situated on the southwest flank of the Jurassic to Cretaceous Coast Crystalline Belt, which is composed of granite, granodiorite, quartz monzonite and quartz diorite.
Locally, the is primarily underlain by a roof pendant composed of metamorphosed volcanics, sediments and intrusions of the Upper Triassic Cadwallader Group and greenschist metamorphic rocks of the Cretaceous to Tertiary Slollicum Schist. The Cadwallader Group consists mainly of andesitic greenstone, tuffs and flows; rhyolitic tuffs and flows with minor limestone lenses; argillite, phyllite, conglomerate and chert. Contact metamorphism is evident along or adjacent to limestone-volcanic contacts, indicated by the development of skarn.
Bands of massive sulphide mineralization up to 2.4 metres wide are associated with a northwest- striking fault within altered andesite adjacent to the andesite-rhyolite contact. The sulphide mineralization consists mainly of pyrite, pyrrhotite, chalcopyrite and sphalerite. Magnetite, epidote, and garnet also occur. The mineralization occurs as skarn lenses in limestone interbedded within the volcanic rocks.
In 1980, a 1-metre wide channel sample assayed 1.8 per cent copper, 0.21 gram per tonne gold, 10.97 grams per tonne silver and minor amounts of lead and zinc (Assessment Report 9003).
In 1994, a chip sample (FR-14) across 50 centimetres of massive sulphides yielded 0.08 gram per tonne gold, 6.4 grams per tonne silver, 0.5 per cent copper and 0.1 per cent zinc (Assessment Report 23366).
Considerable work has been done on the property by a number of companies, and has been concentrated on two areas: the Lake Adit and Eagle (North Eagle, MINFILE 092JSE008) occurrences. A single adit was originally driven on each occurrence between 1915 and 1923. Open-cuts, shallow pits and several copper showings were excavated between the two adits. Regional mapping by Cairnes in 1924 revealed the Lake Adit prospect was hosted within a regional mineralized zone 5.6 kilometres long and 200 metres wide. In 1929, Howe Sound Company drilled three diamond- drill holes beneath the Lake Adit prospect. In 1969, the Lake Adit prospect and surrounding area were explored by Cerro Mining Company of Canada Ltd. In 1980, H. Kim, consulting for Regulus Resources Inc., channel sampled the Lake and Eagle adits. In 1985, Lawrence Mining examined the property. During 1986 through 1988, Green Lake Resources Ltd. completed a detailed exploration programs, including rock and soil sampling, geological mapping, geophysical surveys and diamond drilling on the area as the Lill claims. In 1990, British Columbia Geological Survey geologists mapped a new roadcut along Lillooet Lake and near the Lake Adit prospect. In 1992, A. Kikauka conducted an exploration program in the vicinity of the Lake Adit prospect. In 1994, Guardian Resources Corp. requested Ashworth Exploration conduct exploration on the Lake Adit prospect.
