How to Get Building Materials in Mr. Mine

1. Treasure Chests

Regular chests and gold chests present players with opportunities to obtain Building Materials.

Getting Building Materials from Chests

Regular chests yield one, while gold chests grant a substantial haul of 20 to 50 Building Materials.

2. Scientists

Scientists in Mr. Mine also contribute to the acquisition of BMs in Mr. Mine.

Building Materials from excavations

Depending on your progress, scientists can provide 10 Building Materials before reaching 600 kilometers and 2 thereafter.

3. Caves

As players venture deeper into the mineshaft (after 45km), caves randomly appear, presenting multiple treasure spots filled with Building Materials.

Each cave in Mr. Mine has multiple treasure spots, which may randomly contain 10 BMs. And multiple caves can spawn simultaneously. So, caves stand as the primary and most efficient source of BMs.

Besides, use your drones wisely to explore caves and gather BMs efficiently. Monitor their fuel and health, ensuring optimal performance.

Furthermore, exploring caves brings additional rewards such as buffs, monetary gains, and even chests.

Frequently Asked Questions

Building Materials hold significant importance in the game progression of MrMine. And it is no surprise that many players frequently ask questions about how to obtain these valuable resources.

Let’s address some common questions!

How Can I Make Building Materials?

You can’t actually make BMs in Mr. Mine. You have to obtain it through chests, caves, and scientists.

How Do I Get a Lot of Build Materials?

There are no strategy or game guides for this. Instead, you can find BMs in chests, caves, and from scientists. Moreover, the Book of Ingenuity relics can help a lot since it can increase the chance of finding BMs in basic chests by 6/12/16%.

Is the Manager a Good Way to Spend My Only Building Materials?

It isn’t wise to upgrade the Manager but once. Instead, you should focus on other important structures, such as the Oil Rigs.

Without Relics, What is the Best Way to Get a Lot of Building Materials?

In clicker and incremental games, the best way to get more resources (BMs, in this case) without relics is just to play more. Like basically everything else, they just accumulate over time.


Building Materials are integral to the progression and enjoyment of Mr. Mine. Acquiring them through chests, scientists, and cave exploration will pave the way for a rewarding gaming experience.

That said, you can always check out Mr. Mine game community and other socials, such as TikTok, to learn more about the game.

Embrace the challenge, strategize your actions, and unlock the vast potential hidden within the depths of Mr. Mine – a game about mining!
