The *Sims 4* Blast from the Past event is back, sending players on a nostalgic scavenger hunt to unlock exciting new rewards. This time around, the challenge leads Sims deep into the world of retro-futuristic resources—Plathinum and Ironyum. While tracking them down might sound tricky, there's a reliable method to find these rare materials quickly and efficiently. Here’s everything you need to know about locating Plathinum and Ironyum in *The Sims 4* during the Blast from the Past event.
How to Find Plathinum and Ironyum in The Sims 4
Once you’ve progressed through the “Echoes of Time” portion of Week 2, you’ll unlock the next quest line: “Inventing the Past.” This phase tasks you with gathering two unique resources—Plathinum and Ironyum—for Emit. Unlike previous hunts that felt like guessing games, this one follows a predictable pattern, making it much easier to complete.
The key to finding both Plathinum and Ironyum lies in the same mechanic used to locate the Special Time Capsule. Simply head to any community lot with natural terrain features—parks are ideal spots. Look for areas with visible rocks or dirt mounds scattered across the ground. Once you spot one, pause the game to scan the environment carefully. Approach the mound and select the “Dig Here” interaction. It might take a few attempts, but eventually, your Sim will unearth either Plathinum or Ironyum.
If resources aren’t spawning fast enough, you can speed up the in-game time to encourage new mounds to form. Just be cautious not to skip too far ahead—you don’t want to miss the digging window and lose your chance to collect the materials. Once both items are secured, you’ll unlock the next objective: building the Time Travel Component.
