Lode Loader - it loads lodes!
This modification provides you with a config file, that enables  any custom ore to be found and excavated by Immersive Engineering's  Core Sampler drill and Excavator. Below is an example config file and explanation of usage:

[
  {
    "unlocalized_name": "Anthracites",
    "mineralChance": 80,
    "failChance": 0.2,
    "ores": [
      "oreCoal",
      "oreDiamond"
    ],
    "chances": [
      0.99,
      0.01
    ],
    "localized_names": {
      "pl_PL": "Antracyty",
      "en_US": "Anthracites"
    }
  },
  {
    "unlocalized_name": "Phosphates",
    "mineralChance": 20,
    "failChance": 0.2,
    "ores": [
      "oreApatite",
      "oreSaltpeter"
    ],
    "chances": [
      0.7,
      0.3
    ],
    "localized_names": {
      "pl_PL": "Fosforyty",
      "en_US": "Phosphates"
    }
  }
]

"unlocalized_name" - default name of the added lode ("desc.ImmersiveEngineering.info.this") should be written as one word, no spaces, as short as possible.
"mineral_chance" > 0, each ore lode you add here redistributes the chance to find a chunk with them proportionally
"failChance" >= 0, when digging, this is the probability of an empty "spoon" in the excavator
"ores" and "chances" - ore dictionary names of ores and the respective chance that the current excavation gives you that ore "chances" have to total 1
"localized_names" - provides translation strings for the added lodes
