An anonymous reader writes "In the 60s and 70s Sweden, Russia and Finland were the foremost players in the game of ore dogs, using dogs to sniff out ore deposits for mining. The technique was forgotten in the last century, but this article shows they're now being used again to discover ore deposits. From the article: 'The keen noses of sniffer dogs are proving so successful at locating ore that even the mining giants are sitting up and taking notice.
