Where To Find Plathinum & Ironyum in The Sims 4 Blast From the Past Event

Author : Jonathan Mar 04,2025

Unlocking the "Inventing the Past" quest in The Sims 4's Blast from the Past event requires locating Plathinum and Ironyum. This guide simplifies the process.

Finding Plathinum and Ironyum is straightforward: it uses the same method as finding the Special Time Capsule.

Locate an area with rocks and dirt mounds (parks are ideal). Pause the game to carefully scan the area. Once you spot a diggable spot, interact with it. It might take a few attempts, but you'll eventually unearth both Plathinum and Ironyum, progressing to the Time Travel Component creation quest.

If rocks and mounds are scarce, speeding up in-game time can hasten their appearance. However, avoid prolonged time acceleration to prevent missing digging opportunities.
