The Herb claim is located about 4.5 kilometres north-west of the confluence of the Turnagain and Cassiar rivers, about 110 kilometres east-northeast of Dease Lake, British Columbia.
The following quote is from B.C. Government site “Minfile”- Minfile No. 104I 031, current to 2020:
“The area of the showing is mapped as undivided sediments and metasediments of the Upper Proterozoic Stelkuz Formation (Ingenika Group) and Lower Cambrian Boya Formation (Ingenika Group). Rocks may include sandstone, siltstone, shale, slate, limestone, phyllite, quartzite and schist. The Turnagain pluton, of the Early Cretaceous Cretaceous batholith, consists of biotite granite and intrudes this package in the showing area.
Nearby, rocks of the Upper Proterozoic Ingenika Group including the Espee, Swannell and Tsaydiz formations occur. The Espee Formation consists of crystalline limestone, sandy limestone and dolostone. Undivided strata of the Swannell and Tsaydiz formations consisting of phyllite, schist, phyllitic limestone, siltstone, quartzite and conglomerate covers significant areas. A few kilometres to the south of the showing area, the Cassiar batholith intrudes the country rock. The batholith consists of granite, quartz monzonite and granodiorite.
Galena and sphalerite occur as veins in highly kaolinized granite. Silver is also reported (Geology and Exploration in British Columbia 1972, page 544). Limonite and manganese staining is widespread.”
More details regarding the regional geology can be found in Gabrielse (1998).
Comments by Giles Peatfield regarding one of the minerals reported:
‘potosíite’: This was originally identified in specimens from the Herb claim by Kissin and Owens (1986). The mineral has since been discredited (Moëlo, et al. 2008), and is now regarded as a variety of franckeite.
