Pyrite Lode

Every glittering nugget that rolls off your conveyor could be real gold or
worthless pyrite, and they look nearly identical. Drag each ore across your
unglazed porcelain plate: real gold leaves a golden streak, fool's gold turns
greenish black. Judge fast, swipe left to bank gold or right to scrap it.

Later waves bring bigger ores that need longer strokes, plus brittle sulfides
that shatter under a heavy hand. Wrong calls cost reputation. Score = accuracy
x banked gold grams. Upgrade your bench with 6 working tools: a bigger plate,
a slower belt, an assayer magnifier, a steady glove, a reputation charm and a
master apron skin. How long can your assay office stay trusted?
