Bug - Deposits & Mine

[GRB3396]

In Sector 1 - 1 Marble Deposit
In Sector 5 - 1 Stone Deposit and 1 Iron Ore Mine

My map shows depleted deposit or mine but geologist fails to find them

Any ideas?

yep, you can only have a certain number of these in operation at a time.
Both of the deposits you listed are an either/or, although it looks like two of them exist, only 1 can be found at a time.
