Although the new version of Jaopca provides the support of custom materials, you only need to register the ore and ingot ingots to automatically load other content.

However, due to the issue of loading of Jaopca, the module mines written by their own writing cannot be correctly identified by Jaopca.

The solution is as follows:

The first solution: Install the additions module and customize ore and ingots. Since the Additions module can be loaded before Jaopca, it can be correctly identified.

After that, you can correctly register the items for mineral treatment.

The second solution: Install the Hammer Metal module and register the corresponding metal in the .json file, which can also be correctly identified.

[Knowing that the mines registered using modules such as COT are invalid, there is no solution for the time being]
