I'm not sure exactly as I haven't read the story in full. But usually in a story about a silver mine, there might be a miner. Miners are often central characters as they are directly involved with the mine.
Perhaps there's a villainous character as well. This could be someone who wants to steal the silver from the mine, or who tries to take over the mine through underhanded means. Maybe it's a corrupt official who tries to extort money from the mine owner or the miners. On the other hand, there could be a heroic character, like a brave miner who stands up against the bad guys and protects the mine and his fellow miners.
Well, another possible theme could be the power struggle. When there's a valuable silver mine, different characters or groups may fight for control over it. This could involve political power, economic power, or just plain dominance within the story's setting. There might be characters who try to take over the mine, while others resist, and all these interactions can form a central theme of power struggle.
I'm not sure specifically as I haven't read the story in detail, but there could be a miner as one of the main characters. He might be the one who first discovers signs of the diamond mine.
There could be a villain - like a greedy person who wants to take the pieces of silver from others. Maybe there's an old wise character as well, like an elder in the community who gives advice on what to do with the pieces of silver. Without reading the story, it's hard to be certain, but these are common types of characters in stories centered around valuable items.

In the 'the girl is mine story', the main characters are likely to be the girl who is the object of the claim. There could be a protagonist among the ones who claim her, perhaps a more assertive male character who is very determined that she is his. And then there could be an antagonist, the other person who also says the girl is his. Their different personalities, motives and actions would drive the story forward, and there might be other characters in the background like neighbors or colleagues who add more complexity to the situation.
The main character is surely the boy. In addition, there could be two main female characters. One might be a long - time acquaintance or friend of the boy who has developed feelings for him over time and believes he is hers. The other could be a new person in the boy's life, maybe someone he met at school or work. These two female characters could be very different in personality. One could be shy and reserved but deeply in love, while the other could be more outgoing and assertive, and both are determined to have the boy for themselves.
