An American company, Cyprus Mining, developed and mined those deposits until the Greek - Turkey dust up. Cyprus Mining finally went away when PD bought it and finally Freeport ended up with the whole thing - not the mine in Cyprus, however. I don’t thing there is any activity there now.
Cyprus is one of the most fascinating places in the world geologically. The rocks there don't normally belong anywhere near sea level. It's discussed in John McPhee's book Assembling California.
