Native Gold of the Borovik Ore Field, Republic of Macedonia (FYROM)

Mineralogical and geochemical study has shown that native gold from the Borovik ore field, Republic of Macedonia (FYROM) is homogeneous in composition, high in fineness, and contains apprecia�ble admixtures of Fe and Cu. The chemical composition of native gold does not depend on the morphology of gold grains that indicates closeness of primary source. The results are similar to previous data on gold geochemistry from the Borov Dol porphyry copper and the Plavica high sulfidation epithermal deposits. Electrum was found in placer gold neither in the Borovik ore field nor at the adjacent Plavica deposit. Pan sampling within porphyry copper and silver–gold high sulfidation epithermal deposits and ore fields allows identification and detailed study of the chemical composition and morphological features of native gold from deposits of these types. This procedure is recommended to be applied at prospect and prospect�and�evalua�tion works. The composition of native gold and morphology of gold grains predict high sulfidation epithermal mineralization in the Borovik ore field
