An old mining exploration technique from the 1960s involving sniffer dogs is being used by a Swedish geologist.
Peter Bergman uses a dog’s sense of smell to locate minerals such as diamonds, gold, copper and zinc.
His company Oredog AB was started four-and-a-half-years ago and aims to persuade mining companies to use dogs to “sniff” out mineral deposits.
The technique is already being used in Finland, Sweden, Canada and Russia.
Bergman is in South Africa, accompanied by his most experienced sniffer dog, Rex, on a fact-finding mission in the diamond mine industry in Kimberley and at the gold mines in Gauteng.
