ONTARIO – The diamonds of the Leadbetter and Leadbetter Extension properties near Wawa, Ont., may be more than 2.6 billion years old, making them the oldest known diamonds found anywhere. The news comes from Val dOr, Que.-based DIANOR RESOURCES, which is earning majority interests in both properties.
Dianor issued a press release saying, Dr. John Ayers of the Ontario Geological Survey and Dr. Mike Hamilton of the University of Toronto have dated a felsic tuff interbedded within the Leadbetter Conglomerate as being 2.697 billion years old. Similar tuffs intersected in drill holes are diamond bearing. This dating makes the deposit the oldest in the world, pre-dating the previous oldest diamond rocks, also in the Wawa area, by 20 million years. It is also a unique diamond deposit in that in addition to diamonds, it contains gold, sapphires and rubies. Numerous diamond indicator minerals are also present in the Leadbetter Conglomerate and the morphology of the grains indicates proximity to primary source rocks. The diamond bearing Conglomerate outcropping on the Mori/Metallex/Dianor joint venture property is the eastern extension of the Leadbetter conglomerate and is believed to be the same age.
