1 Introduction

Svartliden is an open pit that has produced gold since 2005 and has produced about 210 902 onces (Dragon Mining AB). Svartliden is located in northern Sweden is in the vicinity of Skellefte mining district, (fig 1). It is located in a “gold line” that is a tectonic zone that con-tains a large gold occurrences. This was discovered in geochemical anomaly maps. Other elements associated with Au are present and these are As, Sb and Te (Bark et al 2005). The pit is owned by Dragon Mining AB, an Australian based company.
The Svartliden pit is located in the Palaeoproterozoic of the Baltic Shield (Grahn et al 2002).
The gold deposit is hosted in metagreywackes and amphibolite and the metamorphic grade of the deposit is mid to upper amphibolite facies (Grahn et al 2002). The Svartliden deposit is similar to the Archean Yilgarn Craton in Western Australia, which is one of the larger lode-vein gold deposits in the world. The Yilgarn Craton deposits are found in amphibolite and granulite facies terrains (Ridley, 1997).

1.1 Aim of Study:
• To determine the alteration mineralogy that is typical for this type of deposit.
• To describe the chemical composition and zoning of the deposit.
The methods used are optical and scanning electron microscopy (SEM) together with Energy Dispersive X-ray analyses (EDS) on drill cores.
