I'm using this with Expanded Materials - Metals, and when I add

<modExtensions>
<li Class="MinesAutomatedExtension.MineableSettings">
<researchPrerequisites>
<li>MinesAutomated_ResearchProjectDef_minecraft</li>
</researchPrerequisites>
<workOffset>200</workOffset>
<mineableYield>1</mineableYield>
</li>
</modExtensions>

from the this mod, to the chromium def it doesn't show up in the Mine recipe list.
I'm curious if there is something preventing it from working or if I'm missing something.
I've also posted this in the Materials Expanded - Metals mod comments as well. Any help at all would be appreciated.
