anagram

polybasite

Ye Pabst oil.

i'd say the first person was right...

Hi Blondeboy,

I'd definitely go with Rhymer's answer- it is an anagram of your letters and matches the description you need.

Polybasite- grey to black mineral that occurs in veins of silver ore.

Good luck in your competition!

Thanks for that answer, it is definately one of the more obscure veins in silver ore, but having read a bit more about it, going for that. I had tried various anagram webs and they hadn't come up with that, so well done.

just glad to demonstrate your own motto!

Yes it's a good one isn't it, and very true!!
