The Crowberry prospect is hosted within a package of metavolcanic rocks with compositions ranging from basalt to andesite. The prospect is offset into four main zones by a series of late brittle EW trending faults. From north to south these are: the Main Gossan, Middle Gossan, South Gossan, and Garnet’s End. Massive garnetite/garnet pyroxenite is present over ~800 metres of strike length and forms as a replacement of metabasaltic protolith. Lenses of massive sulfide, predominantly pyrrhotite with minor pyrite and chalcopyrite, are present over ~1.6 km strike, and their apparent thickness appears to correlate with the thickness of adjacent garnetite bodies. Massive sulfide is typically in contact with deeply weathered garnet biotite schist and appears with mineralized pyroxenite where alteration is the strongest (main gossan, middle gossan, and south gossan zones). Malachite staining is present on some massive pyrrhotite and garnetite.

The Cranberry prospect occurs at the boundary between the lower and upper Crowberry sequence in the West Crowberry area. Here the upper Crowberry sequence is in fault contact with the Coastal Migmatite Domain and is only about 250 m thick. Mineralization at Cranberry occurs within metabasalt and paragneiss. There is a domain of rusty-weathering paragneiss and intercalated metabasalt orthogneiss about 200 m long and 50 m wide that appears stratabound and is associated with locally crosscutting veins and sills of tonalite. It extends for several hundred metres north and south as several layers of rusty-weathering exhalite or iron formation. A small occurrence of garnetite or garnet-rich pyroxenite associated with semi-massive sulfide < 1 m wide occurs on a small ridge north of the main showing. However much of the Cranberry prospect area is under overburden.

The Blueberry prospect occurs in an F-1 fold refolded by F-2 about 8 km NNE of Crowberry. The lower Crowberry sequence appears within the core of a large syncline. The interior of the fold structure is composed of gossanous metabasalt that is variably altered to garnetite, garnet-rich pyroxenite, and garnet-biotite schist all of which are strongly mineralized with pyrite and/or pyrrhotite. The mineralized zone is approximately 300 m x 300 m in extent. There are increasing amounts of paragneiss towards the boundary with the upper Crowberry sequence as shown on the map. The Blueberry prospect resembles a more proximal expression of a Crowberry-like mineralizing system.

Main Cloudberry Showing

The main occurrence in the Cloudberry prospect area is a zone about 200 m x 200 m of pyritic metabasalt, pyroxenite, and garnetite within the typical Crowberry orthogneiss-paragneiss sequence. There are several occurrences of quartz-rich exhalative material and a ridge of coarse-grained garnetite closely resembling that at Crowberry. Much of the mineralization occurs in pyroxenite along with semi-massive sulfide lenses. It appears that here the upper part of the Crowberry sequence has been removed by faulting, and the sequence faces up to the SW into Eastern Paragneiss Domain across that fault. This occurrence resembles a proximal equivalent of the main Crowberry garnetite and pyroxenite. It is flanked by iron formation and exhalative rocks over strike lengths of several km.

Cloudberry South and East

The Cloudberry South and Cloudberry East prospect areas are located along the (folded) trend of iron formation and/or exhalite that extend southward and thence northeastward around a fold nose displaying several significant gossans. Whereas typical iron formation or exhalite horizons in the project area, like the ones flanking Crowberry, are about 5 to 20 m thick, the ones along strike with Cloudberry range from 25 to 100 m in thickness. Where they include larger amounts of sulfide and especially where steep topographic relief has encouraged mass wasting and rapid weathering, these units generate strikingly large gossans with dimensions in the hundreds of metres.
