Stara Planina Local Geology
The Stara Planina Exploration Permit covers an inlier of Palaeozoic gabbros intruded by Permo-Carboniferous graniodiorite. The permit contains known vein-type bismuth copper-gold-antimony mineralization in the Gradiste area at the Aljin do mine, associated with altered (chlorite and sericite) gabbro, and which was abandoned after World War II.
In addition, the project contains a number of poly-metallic mineral occurrences. On the basis of the proximity of these occurrences to the margins of the felsic intrusions, the geological setting and the element associations, Raiden believes that a number of these occurrences are related to intrusion activity.
Prior to the mining during World War II, what exploration or mineral exploitation activities are unknown. After World War II and the termination of mining, the Stara Planina area was reportedly explored for uranium by former-Yugos lav state agencies which undertook limited exploration.
In the period 2003-2004 previous explorers performed minor copper exploration in the area. Although limited, this exploration activity was the first to document porphyry style potential of the area, on the Gradiste anomaly. Further work was also performed by Reservoir Capital Corp.
Stara Planina hosts a number of different styles of mineralisation. Below left – high grade mineralisation is associated with the now closed Aljin Do Cu-Au-Bi mine; Below centre – Cu-Au mineralisation is associated with the Granodiorite intrusive; Below right – Au mineralisation is associated with the structural deformation.
