The Hornträsk deposit is a Volcanic Massive Sulfide (VMS) type deposit located in the Kristineberg area, Skellefte district, Sweden. A geological investigation was done to analyze the geology, stratigraphy and lithogeochemistry regarding alterations of this deposit. The results of the observations are compared to the deposits of Rävliden and Rävlidmyran. The investigation included seven drill cores within the area. From those cores 50 geochemical samples and 24 petrographical samples were taken. Lithological observations of the drill cores and thin sections indicate similar stratigraphies and structures compared to Rävlidmyran. Those observations are further supported by the geochemical results showing strong similarities between these deposits regarding the geochemistry. The results in general are further supporting the conclusion that Hornträsk is located on the same ore horizon as Rävlidmyran. This is especially based on the occurrence of the sulfide mineralization in the contact zone between the Skellefte and Vargfors Groups which is in a spatial relationship with a carbonate-rich layer.
