MORE than a billion years ago two tectonic plates collided and fused to form a continent.

They also formed a mountain range whose worn-down remnants stretch across most of southern Western Australia.
Gold and nickel has been found at one end of the former mountain range, and a small company has bought leases near the other extremity in the hope of finding payable nickel and copper.

According to Bloomberg the Managing Director left the company soon after this interview.
I was lucky enough to interview one of the scientists who have a new take on Bunbury’s weird black rocks.

They were formed when India broke away from the West Australian coast 137 million years ago.
What we see in Bunbury and Capel is part of a huge lava flow almost as large as Western Australia itself that comes from Gondwana breaking up.
Most of it is now under the waters of the Indian Ocean.

A scientist says West Australians have no need to worry about new oil exploration wells in the Great Australian Bight.

A company wishes to explore for oil, and there have been fears a potential oil spill from the wells would drift westwards to Albany and beyond.
Oil spills expert Monique Gagnon says the heavy crude oil the explorers are seeking would degrade and sink before it had a chance to reach WA shores.

Gold refineries may soon be able to quit using toxic cyanide to process ore.
This chemical is dangerous to work with and without careful disposal, bad for the environment.
Instead, a scientists says they can try an organic chemical that is one of life’s “building blocks” – the amino acid glycine.
It is cheaper than cyanide and can be re-used.
Glycine can also be used to extract copper.

While most of the easy-to-find iron ore has been pegged out in the Kimberley, scientists say there should be plenty more in the Yilgarn goldfields.
The Kalgoorlie Miner 3 May 2014 p 21
In the dim and distant past the region was largely submerged under shallow seas, where layers of iron oxide and silica formed banded ironstone. Later, tremendously hot washes of water and carbon dioxide rose up from the bowls of the earth, turning it into what we call iron ore.
Most of this is now buried under layers of soil and other sediment, but outcrops here and there have similar chemical signatures that scientists can now detect with hand-held devices or even from satellites.

Scientists have been seriously examining an old prospectors’ trick.

Termites and ants can be used to detect base metals and gold to a depth of 1.4 metres.
What was part of Goldfields folklore since the 1920s is now scientific fact.

In the first, a consulting archaeologist and a KLC heavyweight say it is getting easier to destroy archaeological sites in Western Australia.
In the second, the National Native Title Council CEO weighs in along with the WA Aboriginal Affairs minister and another consulting archaeologist.
