The Emerald occurrence is located approximately 2.9 kilometres northwest of the south end of Alleyne Lake and 2.2 kilometres northeast of the south end of Kidd Lake.

Regionally, the area is underlain by the Upper Triassic Nicola Group, which regionally consists of alkalic and calc-alkalic volcanics and intrusions of island arc origin, and which is the principal component of the Quesnel terrane in southern British Columbia (Geological Survey of Canada Maps 41-1989, 1713A). The area lies in the Central Belt or facies of the Nicola Group (after Preto, Bulletin 69). This belt of rocks mainly consists of subaerial and submarine, red or purple to green augite plagioclase porphyritic andesitic and basaltic flows, volcanic breccia and tuff, and minor argillites and limestone. The volcanics are intruded by bodies of comagmatic Upper Triassic to Lower Jurassic diorite to monzonite. The area is characterized by long-lived, primarily north-striking faults and related fracturing, which originally controlled intrusion emplacement. East-striking faults are subordinate, and commonly offset intrusive contacts.

Locally, a shaft exposes chalcopyrite mineralization in augite basalt porphyry of the Upper Triassic Nicola Group (Central Belt, Bulletin 69).

In 1971, a grab sample (32613) from a dump assayed 0.10 per cent copper (Property File - M.K. Lorimer, 1971, page 4).

Work History

A historic shaft, likely dating to the early 1900s, was developed on the occurrence.

In 1971, the occurrence area was held by Dancan Explorations Ltd. In 1972, Krancor Oil & Gas Ltd. completed a program of soil sampling and a 20.0-line-kilometre ground magnetic survey on the area as the Emerald claims. During 1978 through 1980, Cal Dynamics Energy Corporation completed soil and geophysical surveys over the area as the AK claims.

In 1990, MineQuest Exploration Associates Ltd. rock sampled the area as the Ley 1-3, Al 1-2 and Ken claims. In 1992, Pacific Copper Fields Inc. and MineQuest Exploration Associates Ltd. completed a program of geological mapping and rock sampling on the claims.

In 2008, Christopher James Gold Corp. completed a 1113.5 line-kilometre airborne magnetic-radiometric survey on the area as the Big Kidd property.

In 2011 and 2012, Xstrata Copper Canada Corp., on the behalf of Jiulian Resources Ltd., completed programs of prospecting, geochemical (rock and soil) sampling and a 56.8-line-kilometre induced polarization survey on the Big Kidd property.
