Pretty simple going off the title, a PC of mine has acquired the deeds to a planet which he suspects should yield considerable mineral deposits.

Naturally being a work shy PC he has elected to rent out the planet to more determined NPCs and I was wondering what people felt was a good figure to put on something like this. As it stands I've proposed an initial estimate of 42k a year over 25 years, something he isn't too enthused about, or a quick sell for 250k.

As I'm fairly certain I know what he'll spend the money on I'm not too worried about how much he gets, I was more just looking to see if people thought it was reasonable/unreasonable.

Specific monetary figures are pretty much unique to each table imo and if you're comfortable with the purchasing power and likelihoods then sounds like you are all set.

Did you mean to post this in the Rogue Trader forum?

But lets see according to wikipedia... Newmont Mining has a revenue of 9.5 billion, with profits in the several millions annually and has bought single mines in the 10 million range. Mark that up to a planet's worth of mines (lets say 100 good mining locations) and you're looking at 1 billion credits, undeveloped. Although if it's considerable miniral deposits by Star Wars standards, that could easily go up by another factor of 10 or 100.

250,000 now, and another 80 Million upon confirmation of claim and appraisal by our scouts.

BTW, don't leave town until the confirmation goes through... and if it doesn't, we'll want that initial down payment back.

Then the miners move in and the locals kick them out, showing the claims were hundreds of years too late.

Then they come back with corporate mercs and Imperial lackeys and the locals start a full time rebellion. And then search out the original claimant to Make Him Pay.
