Hallo good people, I have about 10 acres of granite rock, is it wise to start a quarry business? How can one start on a small scale? Like with 700k

The laughter must be because you have already decided it is wise...

700k is kidogo coz a stone cutting machine goes for 7 million and you have to add generator costs, cables rails etc - What you can do is enter into a partnership with a machine owner and split the proceeds from the sale of stone - most machine owners do not own the quarries that they operate in and keep on moving to new quarries as soon as they exhaust one - once you exhaust the quarry you can put up buildings on it or reclaim it by dumping red or clay soil from construction sites

Ati hio ni pesa ya bill ya stima.
