Still - I would love to see the formula for the gold payback, including character level and mine level.
I'll try my best ..

CC = constraction costs
LM = lost mining
DAV = daily addad value
AP = amortization period

LM = gold/h * 24 * 15d
CC = 10,000,000 + LM

Since the gold pit produces one percent of the city guard yield for one hour per stage and hour, the daily added value after expansion corresponds to one percent of the hourly city guard yield times 24, or 1/15 of the previous yield, since our gold pit had already had stage 15 before expansion.

DAV = gold/h * 24 / 15stages

AP = CC / DAV + 15days

CC = 254,500.16 * 24 * 15d = 91,620,057.6 + 10,000,000 = 101,620,057.6

DAV = 254,500.16 * 24 / 15s = 407,200.25

AP = 101,620,057.6 / 407,200.25 = 249,55 days

For each further expansion stage, 15 days of construction time are added up only.
Every level up of the char will shorten the amortization period.
Anything else is speculation. We don't know yet if there is a limited capacity of the gold pit.
