Geology Comments

11/08/2000 (A Wilson) - The deposit lies within the Eastern Domain of the Goudreau Lake Deformation Zone. The GLDZ is up to 4.5 km in width and strikes in a gentle sigmoid-form for at least 30 km, subparallel to the stratigraphy and the regional foliation. In the immediate Goudreau-Lochalsh area, the GLDZ is coincident with a major contact between Cycle 2 and Cycle 3 volcanics. There is a strong structural control of the gold-bearing quartz veins systms within each of the 070-075 striking high-strain zones within the deformation zone. The Eastern Domain of the GLDZ is 9 km long and 2 km wide and contains narrow brittle and brittle-ductile high-strain zones displaying dextral, oblique slip displacement. Mineral lineations at the Cline Lake area have a consistent shallow plunge to the east and become moderately to steeply plunging in the Godin Lake area. Within the eastern domain, high-strain zones (as well as laminated, quartz-tourmaline and/or quartz-Fe-carbonate veins, fractures and flesic porphyry dikes) are dominantly parallel or at low angles to the east-striking regional foliation. The eastern domain is truncated on the west by the NW-trending Maskinonge Lake Fault.

Lithology Comments

11/08/2000 (A Wilson) - The deposit is hosted by a series of high-strain zone hosted quartz veins that cross-cut all of the local rock types. The most prominent rock type present is a near vertical, oval shaped granodiorite stock in the immediate Cline Lake Mine workings. The granodiorite is characterized by the presence of blue opalescent quartz eyes. The stock plunges moderately to steeply to the east. Many felsic to intermediate dikes also occur in the vicinity of the mine. They have been mapped as: intermediate dikes (oldest), aphanitic felsic dikes, quartz-porphyry dikes and feldspar porphyry dikes. The mafic metavolcanic rocks in the vicinity of the mine are strongly foliated. In other locations on the property, the mafic metavolcanic rocks are massive to pillowed flows. Minor chert-magnetite iron formation has been observed intercalated within the flows. Early mappers (Bruce 1942) had mapped a series of rhyolite flows interbedded with the mafic metavolcanic rocks. More recently these units have been interpreted as synvolcanic intrusions.

Mineralization Comments

11/08/2000 (A Wilson) - Mineralization consists of auriferous quartz veins and schistose rocks hosted within brittle-ductile high-strain zones. Gold mineralization can occure with, or without, quartz in thin shears accompanied by carbonate, pyrite, and biotite or sericite. Individual veins nearly always carry anomalous gold, but gold values are generally highly erratic. Visible gold is common locally. The quartz in the gold-bearing veins typically has a sugary texture. Gold is usually found in fine particles in or near lenses or grains of fine-grained pyrite. However, gold has also been observed as irregular grains completely surrounded by quartz, as grains moulded onto pyrite grains, as fillings of fractures in pyrite, as small blebs in unfractured pyrite, filling fractures in quartz near pyrite grains and along the margins of galena grains.

Alteration Comments

11/08/2000 (A Wilson) - Alteration is confined to zones of shearing and does not affect large volumes of rock. Underground at the mine, Bruce observed that the wall rocks had not undergone extensive alteration. Alteration consists of variable amounts of Fe-carbonatization, sericitization, pyritization and minor siclicification. The mafic metavolcanics display chlorite, Fe-carbonate, calcite and minor pyrite and quartz alteration. The felsic units display sericite, quartz, pyrite and Fe-carbonate. Fe-carbonatization is the most abundant alteration type associated with the auriferous quartz veins.

Geologist : A Wilson

Notes: A 15 metre wide ductile high-strain zone, known as the Cline-Edwards high-strain zone, lies a short distanct south of the No. 3 adit and the main No. 4 production shaft. This zone crosscuts both the mafic and felsic rocks. Quartz, Fe-carbonate, sericite and chlorite are commonly observed in this zone. Large, milky white quartz veins are common within the Cline-Edwards high strain zone but they are generally non-auriferous. Bruce reported that no ore of any consequence was found within this high-strain zone. This point was supported by the Noranda diamond drilling programme. Bruce indicates that this high-strain zone passes into the granodiorite stock between the 3rd and 4th levels of the underground workings. The productive part of the workings was in the hanging wall rocks of the Cline-Edwards high-strain zone. The most promininent subsidiary feature at the mine is the A fault. It trends 110-115 and occupies a nearly vertical brittel-ductile high-strain zone. Subsidiary structures splay off of the A fault, as well as the Cline-Edwards shear. The most important ore body was the A vein, which lay along the hanging wall side of the A fault. Numerous subsidiary viens branch off the hanging wall side of the A vein and are reportedly localized along the contacts of felsic dikes. No ore was found in the foot wall of the Cline-Edwards shear but mineralization is found in the footwall rocks on the adjoining Edwards property. Little mineralization was found below the 5th level of th mine workings. This appears to be because with increasing depth, the Cline-Edwards high-strain zone progressively encroaches on the near vertical dipping, eastward plunging vein system, and eventually truncates it.
