Barra Resources gold find: More than 10kg/tonne

PERTH: Shares in Barra Resources Ltd soared last Friday after the explorer said it has made a massive gold discovery at the Burbanks underground mine near Coolgardie in Western Australia.
But mining experts said while the find was the largest they had ever heard of, further drilling was needed to ensure the result was not a one-off.
Barra hit a gold intersection yielding a very high 10,300g of gold per tonne– or over 10kg per tonne.
The company believes it is one of the most spectacular gold discoveries in Australian resources history.
“I have been drilling for two decades in and around the Kambalda-Kalgoorlie gold province and cannot recall any intersection of this magnitude,” managing director Dean Goodwin said.
Barra shares soared 25% to A$0.375 before ending up 22.8%, or A$0.065, at A$0.35, on solid turnover of 2.38 million shares.
Goodwin told AAP the next largest intersection he had seen – graded at 4,400g per tonne – was found when he was working for Western Mining at the Intrepid deposit under the Lake Lefroy project, close to Kalgoorlie.
“I think Western Mining still holds the record for the highest intersection,” he said.
“This 10,300g per tonne just blew me away – it just eclipses anything that I’ve ever seen.”
The more than 0.21m intersection was part of a longer 4.69m intersection that graded a huge 462.1g per tonne gold in a hole that was the deepest ever drilled on the field.
Barra now plans to intensify its drilling around the discovery, which is not near Burbanks’ previous historical underground workings and is well below current mine development.
Goodwin said the intersection was the first of six holes planned in the current drilling programme.
The hole in question “remains wide open”, he said, so the full extent of the mineralisation system is unknown.
Drilling had been halted for the Christmas break but will recommence in the second week of January. – AAP
