EMDF: Expert assessment of the manganese deposit
Azikan/Jazibasi No. 200807985
3.1 Deposit analysis
The deposit is a classic mountain slope deposit, on the surface of which minerals are visible, probably originating from lenses. The deposit is still undisturbed.
A detailed statement regarding the underground and the ore expansions depends on the results of future supportive mirror investigations and exploratory drillings.
The deposit was examined by EMCP AG on three different dates, the GPS coordinates of
sites of mineral finds were mapped, handpieces collected, and composite samples prepared for further laboratory investigations. The location of those sites within the limits of the authorization field is documented in Annex 5. Representatives of ACEM were present during all three surveys (see photos in Annex 6).
The size of the deposit was mapped based on optically recognizable expansions of raw materials deposits and the expansion verified and calculated using a CAD system (see Annex 7).
The minerals found are mountain-integrated manganese ores and in one find iron ores.
These rocks and ore samples were geochemically assessed as a mixture consisting primarily of silicates associated with carbonates, showing clear signs of hydrothermal-metasomatic overprint. The high ratios of Si/Al and Mn/Fe and the average non-ferrous metal values correspond to the occurrences of hydrothermal manganese deposits from Cayirli [Öztürk, 1997]. The deposits are likely to include multiple lens-like ore bodies of small size with a depth difficult to estimate, which formed in hydrothermal discharge and circulation areas. Consequently there is a high risk premium associated with the determination of the deposit content.
In 1997 Öztürk classified the Anatolian hydrothermal manganese deposits as hydrogenetic and rare diagenetic manganese deposits. They come in the form of lenses and smaller ore deposits in ophiolite melanges of suture girdles and are usually associated with radiolarian pebble rocks. This description corresponds with the picture emerging for the deposits analyzed here.
