Asteroid Prospecting and Mining - rule book, supplement, whatever?

[KjetilKverndokken]

I looked through my M-Traveller pdf's and found that i have beltstrike, and it seems to give a very good job of describing what is needed in this thread. the only thing is to find out how to convert the M-Traveller credits to gurps Dollar, is it one for one or what?

Example was

1 tonne of radioactive materials was worth 1.000.000 creds
1 tonne ice was worth 75 creds
1 tonne Crystals 20,000 creds
1 tonne Dense metals 50,000 creds
1 tonne Carbonaceous material 75 creds
1 tonne Nickel Iron ore 1,000 creds
1 tonne Nickel Iron planetoids 400 creds
1 tonne Uncommon Ore 5,000 creds

The book also had a table for how many % of the total weight of the asteroid was valuable to be mined. Hard and fast descriptions of type of minerals, prospecting tables and the lot, everything could be converted to be used in Gurps, but the only thing is calculating Traveller creds to gurps dollar.
