Need a Materia guide for Miners

So listen guys, I'm a Lv50 Miner, just made it last Friday. I worked hard in them mines and saved enough to buy all my new gear, Miner's set and the best accessories, and all in HQ. Now I'm moving on to Materia. Can anyone give me a guide, or just tell me what Materia I need in what item as to maximize my mining. I don't quite understand caps or the Materia mechanices as I've not really used it. Thanks, and here is the gear I have. As stated, all but Mammon is HQ.
