A group of mine-related stocks in Indonesia[Stock Investment]

I started trading Indonesian stocks at the end of last year, and I'm looking for various things to know more about stocks.
As a feature, there are still many mining stocks and coal mine stocks.
The number of stocks handled by SBI securities(Securities company in Japan) I use is as low as 73 (as of 2021/01).
I summarized mine stocks, which can be traded even in small numbers, for my own reference.
It is classified by the central commodity. The data is based on data from SBI Securities in 2021/01.
Financial indicators are also listed in only a portion.

Summary

Is it an impression that there are many mainly coal-related products? Copper and tin seem to be produced a lot in Indonesia as the production of minerals in the world.
However, in the SBI brand, only "Tima (TINS)" is treated as tin.
There are the following three mining stocks other than coal.
Aneka Tamban (ANTM)
"Vale Indonesia (INCO)"
"Tima (TINS)"
If you look into the homepage or in detail, you can see the minerals you are dealing with. Also, I will update it when I examine it.
