Recently, there is a company approached us saying that there is iron ore in my land and offered me a 2-year contract for mining the iron ore.

However, before making any final decision, I would like to find out what can I do or what shall I do to protect my own interest as I have no clue whether I am in a fair deal and whether I shall find a company to explore what kind of mineral is there in my land and what's the valuation.

Can anyone give me some advice ? Thank you.
