It is completed by talking to a research assistant and handing over the required components, after which the unlocks listed below become permanently available for the rest of the playthrough.

88 Mineral Excavation Efficiency Research is the final node on the brimstone / mining branch of the Gorthak Ironworks research tree. The research assistant is stationed just above the Zagen Tank Works site in Gorthak, in the same building used for Weapon Heat-Treatment Research and the machine parts chain.

1212 Mineral Excavation Efficiency requires the earlier Brimstone Research to be completed first, which itself sits behind smelting research. You will have full access to the Gorthak assistant at the end of Chapter 10: Counterattack and through Chapter 11: Truth and Reality. Like the other Gorthak nodes it costs silver plus a full day of research time.

1616 This is one of the few research nodes that benefits every playstyle. The mining bonus applies to any character who swings a pickaxe or uses the Mining Knuckledrill, and the cannonball cap bonus stacks on top of the earlier Brimstone increase, giving cannon-focused builds their final ammo buffer.

2121 This is rated as one of the highest-value research nodes at the Gorthak institute because the mining bonus benefits every build, not just cannon users. Refined crafting recipes in the late game consume large quantities of ore, and this research is the cheapest long-term way to keep up with demand. Prioritize it immediately after unlocking the brimstone node, and well before any of the weapon blueprint research that does not advance you toward the A.T.A.G. Laser.

The extra yield is multiplicative on top of base drops, so bad mining technique caps your real gains.Pair this research with the Electric Tool Design Research node at Dewhaven, which unlocks the hand drill dispatch for automated mining.Visit the Best Mining Locations and run laps once this is active; the percentage bonus is most obvious at dense ore clusters.If you plan to play Damiane or Unker, the cannonball cap bonus is essentially free ammo for the cannon build. See Replenishing Cannonballs for the full stack breakdown.
