The Bayonne Mine is located between 1830 and 2137 metres elevation on the west side of John Bull Mountain (see Google Earth) in the Summit Creek watershed, approximately 24 kilometres east-southeast of Salmo, Nelson Mining Division.
The official principal (B.C. Minfile) name for this occurrence is BAYONNE (L 5083), which is one of several claims listed on the Minfile page for this property.
The following quote is from the B.C. Government site “Minfile”- Minfile No. 082FSE030:
“The area is underlain by Late Precambrian Horsethief Creek series green argillaceous quartzite, limestone and coarse sediments. The Horsethief Creek series is intruded by Mesozoic fine to medium-grained granodiorite. The showing occurs near the southwest end of the Bayonne Batholith, a northeast-trending, elongate, 60-kilometre-long granodiorite body. The Bayonne Batholith is often gneissic in nature, varies in composition from granite to calcic granodiorite and contains various phases including coarse-grained, fine-grained, porphyritic and nonporphyritic.
The Bayonne occurrence is immediately underlain by the Mine Stock, an intrusive body believed to be older and separate from the Bayonne Batholith. Mineralization consists of quartz-filled fissure veins striking northeast and dipping vertically. The veins vary in width from a few centimetres to a maximum of 3 metres, with an average width of 0.5 metre. Gold and silver are intimately associated with pyrite, galena, sphalerite and chalcopyrite.
The Bayonne mine is a small historic producer (80 903 tonnes averaging 16.1 grams per tonne gold and 38.4 grams per tonne silver) from small (0.1 to 0.5 metre) quartz-filled fissure veins. The veins occur in biotite hornblende granodiorite of the Bayonne Batholith, which is altered to a talc-carbonate rock for 0.5 to 1 metre on either side of the fissure. The fissure contains one or more quartz veins with mineralization in well-defined shoots. An oxidized zone extends down the veins for 137 metres, where it is abruptly truncated by unoxidized primary sulphides. Mineralization consists of pyrite, galena, sphalerite, chalcopyrite, tetrahedrite with minor free gold, hessite and petzite.”
Comments by Giles Peatfield regarding minerals reported:
Anglesite: This mineral was reported by Davis (1937) based on polished section examination. Given the comment below for cerussite, it should be regarded as tentative.
Cerussite: This mineral was reported by Hall (1941) based on polished section examination. Given the comment above for anglesite, it should be regarded as tentative.
Covellite: This mineral was reported by Hall (1941) based on polished section examination.
Hessite: This mineral was reported by Warren, et al. (1938). Unfortunately I cannot find this paper, and Rice (1941) has a cautionary comment, viz. “. . . Warren (1938, pages 30, 31) reports that hessite (silver telluride) and petzite (gold-silver telluride) may occur [my emphasis].” I can find no further analytical data for hessite at Bayonne, and its occurrence here must be regarded as tentative.
Petzite: See comment above re hessite.
