The planet is warm and comfortable, with a short year. It is not particularly mineral rich, though it does possess several large deposits of precious metals and other natural resources.
The planet's biosphere was early in its life cycle, having only recently transitioned from a cold, ice-covered world as its star's surface temperature rose. Plant life had emerged within recent history, providing the planet with a breathable atmosphere, but having not yet given rise to large animal populations.
It seems likely that the original settlers were primarily interested in colonization rather than short-term exploitation of the planet.
