Dec 07, 2005 (B Schnieders) - Hinz and Landry (1994).
Dec 07, 2005 (R Degagne) - The area in which the occurrence is found has not been mapped. Extrapolating from mapping conducted by Carter (1989) to the east, the occurrence is underlain by the Archean age Whitesand Lake Batholith. Carter (1989) stated that the batholith, 'extends in an east-west direction for 16 km - and in a north-south direction for about 8 km but extends westwards and southwards beyond the limits of the map-area'. The batholith is comprised of medium - to coarse-grained alkali-feldspar granites with a grey phase ranging in modal composition from monzodiorite to quartz monzonite.

Dec 07, 2005 (R Degagne) - The Halonen occurrence consist of a series of veins and breccia zones which host amethyst, barite, fluorite and epidote mineralization. In some places the amethyst occurs in vugs and displays pale to dark purple colours with some red. The crystals are drusy to palisade with well developed pyramidal crystal terminations. Barite is pink in colour with bladed to sheaf-like crystal form. Some epidote is seen within the vein material as a dark lime green mineral.
Apr 29, 2019 (Therese Pettigrew) - The vein strikes east-west and dips approximately 80S. It is 0.6-1.5 m wide and has an exposed surface length of 8 m. The east end of the vein is barite-rich while the west end is fluorite-rich. Amethystine quartz is mainly pale purple in colour; fluorite varies from deep purple to greenish yellow. One large vug, 23 cm high, 30 cm wide and 100 cm deep is exposed. A grab sample from the west end of the vein assayed 8.31% total barium, 26.4% total calcium, and 25.5% total fluoride; a sample from the east end assayed 41.7% total barium (Fenwick and Scott, 1977).
Dec 07, 2005 (R Degagne) - Epidote alteration is pervasive within the brecciated host rock and wallrock. Some epidote is seen within the vein material as a dark lime green mineral.
