Abstract
This paper presents study of the chemical composition and forms of gold
aggregates that were found during schlich prospection along the Stara Reka and Lukar river
in the Kozuf volcanic area, which is associated with Tertiary magmatism in the R .
Macedonia. Study have shown that it is native gold characterized by high purity ranging from
892 to 994 with certain impurities. Silver concentrations range from 0.57 to 11.61 %Ag, other
impurities (Fe, Cu, Se, Te, Bi) are present under 1 % in total. Morphological forms of gold
usually with irregular-isometric shapes dominate, while it can be seen elongated and round
shapes too. The size of the gold aggregates ranges from 100 to 200 μm.
