The Gold Mine is one of the main resource buildings in Last War: Survival. It produces Coins used for building upgrades, especially after your base reaches the middle and later stages of progression.
Upgrading the Gold Mine at the right time helps you avoid Coin shortages while improving your overall base power. This guide explains Gold Mine levels, upgrade requirements, production rates, and the best ways to increase your Coin income.
Why the Gold Mine Is Important
The Gold Mine is your primary source of automatically produced Coins. These Coins become increasingly important because many building upgrades from level 9 onward require them alongside Food and Iron.
A neglected Gold Mine can slow down your Headquarters, research facilities, troop buildings, and other important upgrades. Therefore, it should develop alongside your other resource buildings rather than being left several levels behind.
Players planning their wider base progression should also review the Last War Headquarters upgrade guide. Headquarters requirements often determine which supporting buildings and resources you need to prioritize next.
Gold Mine Upgrade Costs and Production by Level
Each Gold Mine upgrade increases the number of Coins produced per hour. However, the required Food, Iron, Coins, and construction time also increase considerably at higher levels.
Use the table below to estimate your upcoming resource requirements and decide whether you should upgrade immediately or save resources for another priority building.
Keep the following details in mind when using the table:
- The listed requirements are base values, so research, buffs, and other bonuses may reduce the final costs or upgrade time.
- The Training Base has similar upgrade costs, construction times, and power increases.
- The maximum Gold Mine level is 30, with a base output of 21,600 Coins per hour.
- Actual Coin production can change depending on research bonuses and the survivors assigned to the building.
- You should plan Food and Iron production alongside Coin production because all three resources are required for many later upgrades.
For balanced resource development, compare these requirements with the Last War Iron Mine guide. This can help you prevent one resource from becoming a bottleneck while preparing for expensive building upgrades.
How to Increase Gold Mine Coin Production
Upgrading the building is the most direct way to increase production, but it is not the only factor that affects your total Coin income. Several systems can improve output or help you complete Gold Mine upgrades faster.
- Improve relevant research: Prioritize research that increases resource production, construction speed, or economic efficiency.
- Assign suitable survivors: Place higher-level survivors with useful production bonuses in the Gold Mine whenever possible.
- Use production boosts carefully: Activate boosts when you expect to remain active or when you need additional Coins for a planned upgrade.
- Request alliance assistance: Alliance help can reduce construction time and allow you to complete building upgrades sooner.
- Collect resources regularly: Avoid leaving produced Coins uncollected for long periods, particularly if the building has limited storage capacity.
When Should You Upgrade the Gold Mine?
You do not always need to upgrade the Gold Mine as soon as a new level becomes available. The correct timing depends on your current Coin balance, Headquarters requirements, event objectives, and construction queue.
Prioritize the Gold Mine when:
- Coin shortages are delaying important building upgrades.
- Your Gold Mine is significantly lower than your other resource buildings.
- You are preparing for several expensive upgrades.
- An event rewards building power or construction activity.
- You have enough Food and Iron to complete the upgrade without disrupting another priority.
You may delay it temporarily when your Headquarters, Tech Center, hospital, troop buildings, or another required structure is more important to your immediate progression.
Common Gold Mine Upgrade Mistakes
One common mistake is focusing only on the Gold Mine while ignoring Food and Iron production. Coins may become important at higher levels, but building upgrades usually require a combination of several resources.
Another mistake is beginning a long upgrade without checking upcoming Headquarters requirements or event schedules. A construction queue occupied at the wrong time can prevent you from completing a more valuable upgrade.
Finally, avoid spending every available Coin immediately. Maintaining a reserve gives you more flexibility when an important building, research project, or event objective becomes available.
Frequently Asked Questions
What is the Gold Mine used for in Last War: Survival?
The Gold Mine automatically produces Coins. Coins are used for many building upgrades, particularly after your base reaches level 9 and above.
How do I increase Gold Mine production?
Upgrade the Gold Mine, improve relevant research, assign suitable survivors, and use production boosts when they provide meaningful value.
What is the maximum Gold Mine level?
The maximum level is 30. At level 30, its listed base production is 21,600 Coins per hour before additional bonuses.
Does alliance help work on Gold Mine upgrades?
Yes. Alliance members can provide assistance that reduces the remaining construction time.
Are the upgrade costs in the table exact?
They represent base values. Research, construction bonuses, survivor effects, buffs, and game updates may change the final requirements shown on your account.
Should beginners prioritize the Gold Mine?
Beginners should keep it developing alongside other important resource buildings. However, it should not automatically take priority over the Headquarters or structures required for immediate progression.
Why am I running out of Coins?
Coin shortages usually happen when several high-level buildings are upgraded close together, the Gold Mine is underleveled, or economic research and survivor assignments have been neglected.
Conclusion
The Gold Mine supports long-term base development by providing the Coins required for increasingly expensive upgrades. Keep it reasonably close to your overall base level, improve economic research, assign suitable survivors, and coordinate Coin production with your Food and Iron supply.
Planning upgrades in advance is especially important at higher levels, where construction requirements and waiting times increase sharply. A balanced economy will help you progress more consistently without allowing one resource to delay your entire upgrade plan.
