Build raw material industries
This setting will enable you to purchase and either prospect or place industries which create raw materials.
Normally, you are only allowed to purchase industries which process materials, e.g. Factories, Sawmills, etc. When this setting is enabled you are also allowed to build raw-material producing industries such as coal mines, iron mines, etc.
When the prospecting construction method is selected, you will be able to purchase a new industry of the selected type, but the industry will appear in a random location on the map.
This does not affect which types of "naturally occurring" industries which show up, just which ones you are able to purchase.
Construction of primary industries is disabled by default. When enabled, the list of industries you can purchase will include industries which produce the raw materials, with appropriate pricing. You can enable this setting through the Advanced Settings -> Economy -> Industries -> Manual primary industry construction method window or use the following syntax in openttd.cfg:
[construction] raw_industry_construction = 2
0 = none, 1 = as other industries, 2 = prospecting
Valid options: [ 0 | 1 | 2 ]
It can also be set in the console using the command (single player games only):
set raw_industry_construction <value>
List of fundable Primary Industries
|Name||Cost without inflation||Notes|
