Walaalo, you know there is a lot of tension between Turkey and Greece, and also the Syrian War, and the treasure you mentioned is said in the hadiths to be found in the Euphrates River, and another end times signs in hadiths is that river drying out
1) Turkey have a dam in that river, and its weird cos last year 50 tonnes of gold was taken forcibly away from Daesh in the east of the Euphrates to the US army,
2)The river is drying up fast and has been due dams from Turkey but also from Syria and Iran
I am imagine it would dry up to such an extent that gold was or will be detected.
Allahu Alam/Allah knows best, I may be wrong
