“…4), and includes the producing world-class Kadjaran deposit (27.2 ± 0.1 to 26.43 ± 0.11 Ma), and the past producing Paragachay deposit (26.78 ± 0.11 Ma). According to K-Ar ages published by Bagdasaryan et al (1969), epithermal mineralization is associated with both Eocene and Oligocene magmatic activity, at 37.5 ± 0.5 and 38.0 ± 2.5 Ma at the Tey-Lichkvaz gold prospect, and at 24 ± 1 Ma at the Atkis polymetallic prospect near Kadjaran (Figs 3b and 4). On a world-wide comparison, the porphyry Cu-Mo deposits of the Zangezur-Ordubad region have modest metal contents, except the undated Eocene to Oligocene Misdag deposit and the 26-27 Ma-old Kadjaran deposit (Fig.…”

“…The composite Meghri-Ordubad and Bargushat plutons are also exceptional because they host within a small area several stages of Eocene to Miocene precious and base metal epithermal and porphyry Cu-Mo deposits (Bagdasaryan et al, 1969;Babazadeh et al, 1990; Melkonyan…”

“…The Tejsar area consists of igneous units that are predominantly mid-Eocene in age together with occurrences of Oligocene to Pliocene rocks (Bagdasaryan et al, 1969). These Cenozoic rocks are emplaced in a Neoproterozoic basement (Meliksetian, 1989(Meliksetian, , 1971.…”

“…One of the main outcrops of Precambrian metamorphic basement rocks in Armenia is located in the basin of Hrazdan. Predominately, however, the area is covered by Quaternary lithologies, including Pliocene lavas aged 5-10 Ma [22]. The area lies in the Arpa-Vorotan zone of uplifts and troughs, which correspond to a major Paleogene syncline.…”

This study presents an evaluation of arsenic and other trace metals in the Hrazdan Iron-Ore project in Armenia using a methodology typically associated with Geometallurgical characterization. The principal host of the trace elements is pyrite and oxidized equivalents. Pyrite is a mineral of elemental concern as it has the potential to generate acidic pH in water that it contacts and thus mobilize metals of concern. In the Hrazdan deposit, there is a general excess of neutralizing carbonate minerals that result in adequate buffering of generated acid and limiting the mobility of metal cations in solution. However, metalloids that form oxyanions species such as those of arsenic or chromium tend to be more mobile in neutral to alkaline mine drainage. From the geometallurgical assessment of the mine waste, the results of the geochemical testwork can be explained and the information used to assess potential issues with mine waste storage, timing of metal release and provide a baseline for mitigation strategies.
