The Rea occurrence is located 1.5 kilometres south of the south shore of Tahtsa Lake approximately 113 kilometres southwest of the community of Houston.

The showing area is underlain by Lower Jurassic Telkwa Formation (Hazelton Group) pyroclastics, argillites, and cherts that have been intruded by at least two small felsic stocks possibly related to the Late Cretaceous Bulkley Plutonic Suite. The rocks are strongly pyritized locally and contain minor chalcopyrite, molybdenite, and silver mineralization.

Outcrop is not abundant on the property and is confined almost exclusively to creek valleys except in the southeasternmost corner of the claim block (ca. 1971) where topography is steep and outcrop may be found between creek valleys. The main lithologies in the vicinity of the property are a series of argillites, cherts and volcanic rocks (mainly pyroclastic with minor extrusive flows). The two small stocks or plugs are intrusive into the Hazelton Group rocks. Dark grey argillite is exposed along several creeks in the southwestern and central regions of the property. Chert and argillaceous chert outcrop in the southeastern area of the claim block and fragmental volcanic rocks have been found in the east-central, north and west regions of the property. The central portion of the claim block consists mainly of a silicified and pyritized felsic pyroclastic rock and a leucocratic quartz porphyry stock.

Bedding attitudes in argillite in the southwest and central part of the property have a northeast trend (020 to 045 degrees) with dips of 45 to 70 degrees to the southeast. Bedding in chert in the southeast corner of the property strikes approximately 025 degrees and dips 30 to 50 degrees to the northwest.These attitudes indicate the presence of a northeast trending syncline in the southeastern region of the claim block.The larger of the two intrusive bodies is a fine to medium grained, leucocratic quartz-eye porphyry which is exposed in several creek beds in the south central part of the property. This stock is approximately 152 to 762 metres, elongate along a northeast-southwest axis.The other intrusive body is a fine grained equigranular monzonite which is exposed over an area of 15 by 61 metres in the southern part of the property, approximately 762 metres south of the larger intrusion.

In 1969, reconnaissance and detailed soil and stream sediment sampling programs were conducted over the TL and Rea group of claims on behalf of owner Bethlehem Copper Corporation Ltd. In 1971, a detailed geochemical survey was conducted by Bethlehem Copper Corporation Ltd. and comprised line cutting, chaining and sampling.
