Gold Rush Practice Exam 2026 – Complete Test Prep Guide

The idea being tested is how the mining process uses water flow to separate materials and reveal hidden clues. In a sluice box, water carries lighter gravel away while heavier particles, including any small items embedded in the pay dirt, are left behind. The tool from the locked box is used to start or control that flow, so when water is pumped into the sluice box, the wash proceeds and the compass that’s been buried or hidden becomes uncovered. This fits the scenario where progress depends on activating the sluice to reveal the next clue.

Unlocking a lunchbox, mapping the mine directly, or heating minerals don’t align with how a sluice box works or with uncovering a compass during processing.
