[ExI] Space Mining

[Keith Henson]

I think I have mentioned this before https://htyp.org/Mining_Asteroids

"This article provides a rough analysis of mining an asteroid for gold
and other high-value elements (platinum group metals) for return to an
Earth market. Given serious bootstrapping at an asteroid and the
development of low-cost transport to GEO in the context of a power
satellite or similar very large operations in space, it appears an
asteroid-mining project could make money beyond the wildest dreams of
avarice."

12 years ago.

I should update it.
