# Production
In the game, you'll find 5 production buildings - 4 of them are in the **Base** and 1 in the **Fight** tab.
We'll briefly describe them all in one place, since they have a very similar interface.
* **Mine**: Here, you can extract metal ores.
* **Steelworks**: In this facility, you can smelt ores obtained from the mine into Steel, Copper, and Uranium.
* **Farm**: On the farm, you can plant seeds to harvest hallucinogenic flowers.
* **Laboratory**: Here, you can create drugs in the form of crystals by combining two different flowers obtained from the Farm.
* **Shipyard**: This is where you create units that will serve to attack and defend your territories.
Each of the resources produced in the above buildings (except for crystals) can be bought/sold on the Market. Therefore, nothing stops you from simply buying Iron Ore and smelting it into Steel, instead of expanding your own mine.
Everything depends on your strategy, which will be somewhat influenced by **Global Events**, as we mentioned earlier.
## **Mine**
Let's describe the **mine building** as an example.
When entering the building, you need to choose which resource you would like to extract.
Suppose you decided to mine Copper Ore. Thus, you select the **Copper** tab, then **"Develop Mine"** to expand the mine.
As you see, the expansion of the first mine costs **10 Steel and 10 Copper**, but subsequent buildings cost more respectively.
By clicking the **“Develop”** button, you expand the Copper mine and can start production.
In all the production buildings, the setup looks very similar. At the top, you see the production costs, and at the bottom, you can set the amount you want to produce.
In this case, to extract **100 units of Copper Ore**, we need to pay **17 units of Uranium**. Below, we see that our maximum production per turn is **100 units of Copper Ore.**
By clicking the **“Upgrade”** button, you can enhance the Copper mine at any time, increasing its production per turn and reducing production costs.
Since it's the first turn, we don't really have resources for upgrades, so we simply click on the **“Max”** button to produce the maximum amount, and then **"Mine"**.
The extracted Copper Ore can be sold on the Market at any time if you currently don't need it and could use some Amero for other actions.
