Probably in common with many others here, who read all about GGP to try and educate themselves in topics that don't come naturally, I find myself frequently floundering. Understanding the risk within an investment is key to success - will a night parrot build a nest on the explosives store and halt tunelling immediately? If NC have to evacuate Cadia because of a structural weakness in a vent shaft how likely are similar issues in our soft Permian layer? Will a meteorite loom out of the infinite gloom of space and obliterate our precious core shed?

I leave you on your own to do further research on the nesting habits of rare Australian nocturnal birds; and to answer the question how sandy is sand - but I believe I can bring insight to the perennial "will a meteorite strike" worry.

Weekend education is never complete without a quick geology lesson.....

Despite Bamps' numerous attempts, now with illustrations courtesy of this board, the geology remains heavy going, or ">2.7" as I have learnt to more precisely describe it. Within the link above is a link to a second story about the Yarrabubba crater. Clicking on this link has led me to find an answer to "how do you age rocks?", such a basic beginners question I was too shy to ever ask, specially in a public forum such as this. The (partial) answer is that courtesy of the (geological) mess left in a distinctive impact crater you can tell what rock was the proverbial brick wall when the bit of space rock smacked into earth's surface; and the decay of uranium to lead gives the answer to when.

Trust me, the article explains it better.... And with pretty pictures.

Fortesque expansion at Solomon iron ore mine
“The area to be cleared includes six hectares of Brockman iron ore cracking clay, a threatened ecological community and a habitat used by the endangered northern quoll and Pilbara leaf-nosed bat and vulnerable Pilbara olive python.”

Alien Metals are up there at Brockman

Quolls have a taste for flesh

Pilbara Olive python

.....the northern quoll wins it hands down from that list. It's the cute wee furry critter that looks like it stood too close when you were painting the outside of the house.
