Rothenbergstollen (Rotenbergstollen), Goppenstein, Ferden, Bezirk Westlich Raron, Wallis, Schweiz
Group of adits of the Goppenstein lead mine opened along the Rothenberg (Rotenberg). The lower workings are located between 1310 and 1425 m a.s.l., i.e. Tiebel adit (1310) and levels I (1345), II (1360), III (1380), IV (1400), and V (1425); the upper workings between 1690 and 1970 m a.s.l., which include numerous adits (levels 1-10) opened before the 20th century and partly reworked during the five years ending in 1905 (when the mine was operated by the company "Bergwerks-Aktiengesellschaft Helvetia") and in the period 1939-1945. However, the most important adits, located at 1820 m and 1860 m, were opened around 1949 when the mine was operated by Joseph Dionisotti.
The Ag-bearing lode at 1820 m ranges from ca. 5 to 10 cm in width. It consists of sericite schist with a first thicker vein of extremely fine-grained galena intimately admixed with brown sphalerite, enclosing quartz grains and sometimes grains of almost pure sphalerite; a second thinner black vein, embedded in a quartz-baryte gangue, is made of abundant acanthite, scarce galena, sphalerite, and pyrite, and rare inclusions of native silver up to 3 mm in size. A 3-m-long and 2-m-wide area of mineralised fissures at the margin of the main ore body has been recently discovered and studied (Rüegg & Klemm, 2002; Rüegg, 2005). The ore minerals in decreasing order of abundance are black sphalerite, galena, pyrite, marcasite, arsenopyrite, pyrargyrite, argentopyrite, and stephanite. Pyragyrite crystal aggregates, up to 4 mm in size, are always overgrown on other sulfides, preferentially marcasite. Associated crystallised minerals in the fissures in decreasing order of abundance are quartz, calcite, chlorite, rutile, gypsum, anatase, and brookite.
