How would you find ores? There are many steps to finding an ore deposit. Find a place with likely geology.Test the soil and rock for the ore mineral or others that are often found with the ore mineral. Drill to test deeper rock and soil. Then make a map and do the calculations. If the deposit is found to be profitable, you can begin mining.
