Graveyard Keeper 2 golden nuggets & gems
Golden nuggets are not a craft in the demo — they are a probabilistic by-product of the sluice box, and gems are an extra drop from copper veins once the Miner perk is in. This page keeps the two measured numbers: about 40% at the sluice box, 20–25% for gems, plus why the nugget line cannot be handed to zombies.
Golden nuggets come from two places, neither direct
The video sets the scope first: golden nuggets are tied to two places — the sluice box and the formulation bench — and at the sluice box it is not direct crafting, because a perk has to be unlocked first.
the sluice box has exactly one recipe (Tin → Tin + Golden nugget, 5 ticks), so the nugget is a by-product of that recipe rather than a recipe of its own.
In the mechanical branch of the inspiration tree you must take Miner before Gold Digger — the second is locked behind the first.
The perk text says gold starts appearing when sifting sand, which is exactly what the test confirms. Both the Miner and Gold Digger perks exist in the perk data in the game’s data.
The video queues 50 crafts at the sluice box and empties the inventory so the before/after is clean. The box also produces tin, so the nugget column is what matters.
It also runs a control: putting zombies on the sluice box to see whether they produce nuggets too.
The control is unambiguous: the zombies ran the box for more than a hundred attempts and produced nothing. The video’s conclusion is that they simply do not make nuggets.
That makes the sluice box one of the few lines you cannot automate — if you want nuggets, you stand there and press it yourself.
To measure the drop rate the video empties the inventory and mines a copper vein with a full energy bar: one full cycle is three hits = 3 energy, so 100 energy buys 33 cycles.
Thirty-three cycles produced 8 gems — 8 ÷ 33 ≈ 24%, and the video’s stated expectation is “20 to 25%, so about one in four or five”.
Side by side the planning is simple: nuggets ≈ 40% per craft and cannot be delegated; gems ≈ 20–25% per copper nugget.
So for nuggets the correct play is “take the perks, stock the material, sit down and craft”; for gems it is “mine copper veins whenever energy is full”.
Nuggets: manual, 40%
Gems: mining, 20–25%
Both share one perk line
Where this comes from
Recreational Suffering — golden nuggets and gems
The source video (published during the demo window). Its English captions were read in full (136 cues) and checked cue by cue.
the Sluice Box has exactly one recipe in the game’s recipe table (Tin → Tin + Golden nugget, 5 ticks), the nugget itself is in the item list, and both perks — Miner and Gold Digger — exist in the game data. The drop rates (40%, 20–25%) are the video’s measurements; the game’s data carry no probability fields.
Limits: small samples (50 crafts and 33 cycles); the video itself hedges to “20 to 25%”. Rates may move with perk level or patch. The video covers the demo build (1.002.4) and values may change in the full release (2026-09-22).
