Dec 07, 2005 (A Wilson) - The occurrence lies within the western domain of the Goudreau Lake Deformation Zone (GLDZ). The GLDZ consists of a series of brittle and brittle-ductile high-strain zones displaying dextral oblique-slip displacement. The host rocks are the mafic to intermediate metavolcanic rocks of the third volcanic cycle. Gledhill reported a series of quartz-feldspar porphyry dikes in the vicinity of the mineralized veins.
| Rock Type | Rank | Composition | Texture | Relationship | Vein | 1 | Quartz | Host |
|---|---|---|---|---|
| Mafic lava flow-unsubdivided | 2 | Pillowed, Massive | Near | |
| Quartz-Feldspar Porphyry | 3 | Quartz-Feldspar | Near |
Dec 07, 2005 (A Wilson) - Quartz veins are hosted within massive to pillowed mafic metavolcanic rocks that display weak to moderate deformation. Gledhill describes the quartz veining to occupy an area of shearing. Several quartz-feldspar porphyry sills or dikes have also been reported in the area.
