What would happen if you found gold in your backyard?

If I found gold in my backyards, I would be very happy to see that.
And I will have enough money to buy what I want to buy.
If I found gold in my backyards, I will save most of the golds in my bank account.
Also I will spend some of the gold to improve my daily life, and then donate some golds to poor families. I think in this world there are a lot of poor people that need help, but it is useless to just donate money to them. They will just spend out their money and then have nothing in the end.
So if I found gold in my backyards, then I will have a lot of money to do anything I want.
Therefore I can use my gold to help others, such as seting up a hospital to save patients or helping poor young guys to studying in school. If poor people can use my money to learn a working skills, then they can make money by themself not just depending my golds.
By the way, I can use my golds to invest, and I will get a lot of fortune. After get lots of fortunes, I can spend more money to help others.
So what would happen if you found gold in your backyards? My friends?
