I work for us, a group of tin mines is between 1G-2G, but a group can choose 4 times RP, and 3-6 green agates can produce better!
You can also find a friend who knows jewelry to help you beneficiate. The content of green agate in tin ore is relatively high. Topaz may also be produced when tin ore is selected, and the probability of producing shadow stone and moonstone is very high. Look at RP!
