Province: Superior
Subprovince: Sachigo
Terrane: North Caribou
Geological Age: Archean
Aug 23, 2010 (N Bennett) - The Sachigo Subprovince represents the northernmost extent of exposed Archean basement rocks of the Superior Province. To the west, the Sachigo is bounded by the ~1.8 Ga Trans-Hudson-Orogen (“THO”), while to the northwest the subprovince is in contact with granitoid and mafic/ultramafic rocks of the Thompson Belt, a collisional zone formed during the THO. To the east, the Sachigo is delimited by the Winisk River Fault, which separates the Superior Province from rocks of the THO Fox River Belt, while the southern limit of the Sachigo Subprovince is defined by the Berens River Subprovince, a granite-greenstone terrane (Thurston et al., 1991). Much less is known about the Sachigo Subprovince than the more accessible granite-greenstone belts to the south, with most work concentrating on the handful of isolated greenstone belts found enclosed within the granitic and gneissic units (e.g. Bennett and Riley, 1969; Ayres, 1974; Card and Ciesielski, 1986; Thurston et al., 1991). However, a number of differences can be noted between the greenstone belts of the Sachigo Subprovince and younger greenstone terranes to the south. The Sachigo Subprovince includes some of the oldest ages for greenstones in the Superior Province at 2.9-3.0 Ga (Corfu and Wood, 1986; Thurston et al., 1991) and includes an unusual sequence of quartz-rich metasedimentary rocks within a sequence of mafic and felsic volcanic rocks (Thurston et al., 1991). The Berens River granite-greenstone subprovince, immediately to the south of the Sachigo, is interpreted to represent a deeply eroded arc or micro continental core, while rocks of the Sachigo Subprovince are considered remnants of widespread, early (3.0 Ga) sialic crust (Thurston et al., 1991). Geological similarities between the Sachigo, Berens River, and the Uchi Subprovince, situated to the south of the Berens River Subprovince, have prompted some researchers to define an Uchi-Sachigo-Berens River superterrane (Card and Ciesielski, 1986; Thurston et al., 1991). Granitic rocks represent the dominant lithologies in the Sachigo subprovince and include, from oldest to youngest: gneissic tonalites; foliated tonalites; a muscovite granodiorite-granite series; and a diorite-monzonite-granodiorite suite (Thurston et al., 1991). Pre-tectonic mafic intrusive rocks in the Sachigo subprovince are considered to be synvolcanic by Thurston et al. (1991), and comprise predominantly mafic to ultramafic sills. Post-tectonic magmatism in the northwestern Superior Province includes three diabase dike swarms, comprising the 2171 Ma Marathon Dike Swarm, the 1888 Ma Molson Dike Swarm and the 1267 Ma MacKenzie Dike Swarm. The Big Trout Lake Intrusive Complex represents the largest known exposed mafic-ultramafic intrusion in the general area and consists of a folded 5,000 m thick sill containing a 500 m thick lower ultramafic sequence of dunite, chromite and chromiterich layers overlain by homogeneous peridotite. Two batches of tholeiitic magma are indicated in the formation of the sill (Borthwick and Naldrett, 1984).

Jul 29, 2014 (N Bennett) - DDH TME-08-02: From 147.24 m-147.73 m the section contains massive pyrite with trace amount of fine grained sphalerite, also from 148.05-148.48m semi massive pyrite with trace amount of sphalerite, one tiny blep of sphalerite occuring right at 148.30m which is about 1cm across. Assay results show that from 146.23m to 149.56m Zn ranges from 564ppm to 26,700 ppm (2.67%). Also from 161m-162m Zn measured 1450ppm.
