Note that Dreads are immune to ECM when in siege mode, making it possible to force Dreads to use siege mode against even medium towers with well set-up ECM and guns. Ideally, Caldari towers are used here for the ECM cycle speed bonus.

The next step is to increase the cost of their siege. Now that they are using Dreadnoughts, they will consume strontium clathrates to maintain siege mode. This means that the longer the siege continues, the longer they will be expending strontium and the more ISK they burn. This can be increased by running shield-hardening arrays to increase the POS' shield resistances. Also, the Caldari tower has the most shield hit points, at fifty million.

Every minute that the enemy has a Dreadnought fielded is a minute they risk losing a ship worth several billion ISK to a well-planned counter-attack. The key is to keep enemy Dreadnoughts engaged for as long as possible as you plan a co-ordinated counter-attack.

DEFENCE - HITTING THE PAUSE BUTTON
Your primary line of defense will not be your guns. In fact, if someone resolves to destroy your POS, has the resources to hand and can field Dreadnoughts in siege mode, your guns will not help unless you turn up during the siege. Your primary line of defense is strontium clathrates - it's ironic that the same thing the Dreadnoughts will be using to tear your POS down will help to keep it up.

This acts as a sort of 'pause button' to give you time to react. Your POS fuel tank can hold strontium clathrates. Should the shield be reduced to 25%, it will go into reinforced mode and start consuming the strontium. In reinforced mode, your POS is invulnerable but it cannot regenerate shield, and no modules which require CPU will work. Guns which only require powergrid will work fine. Despite the official word that they consume fuel at an accelerated rate in reinforced mode, they actually only consume the strontium clathrates.

The purpose of strontium is to give you some time to get a force together. If the enemy comes back once your POS comes out of reinforced mode, you should be ready for him. If he doesn't, the shield will regenerate. You can also use remote shield boosters once out of reinforced mode.

IN SUMMARY
From the smallest corps right up to the huge corporate monsters and alliances, moon mining can be a very profitable industry that, unlike other things in EVE, can make you plenty of ISK while you sleep. If you follow the advice in this guide, you too can join the long line of corporations with their very own automatic ISK printing machine.
