At Mining IV you will be able to use the Miner II module instead of the Miner I. The next step is to train the Mining skill to level IV. Given the role bonus of the Venture and the fact that you can use two mining lasers, you should have doubled or quadrupled your ore mining yield. This means that a Venture can fit and use two mining lasers at once. The Venture has three high slots of which two of those can fit a turret. When that is trained you can fly to the next station that sells a Venture and buy it. To be able to fly the Venture you only need to have the skill trained to level I. If you don’t have it already in your skills section you can buy the skill books necessary from the market and inject to start training the skill. To be able to fly the Venture you need to have the Mining Frigate skill and Spaceship Command skill trained to level I. It’s not expensive compared to other frigate class ships and will vastly improve your mining yield, both ore yield, and gas cloud harvesting yield. The Venture is a specialized mining ship made by the ORE corporation in Eve Online. The first ship you should buy for your newfound mining career is the Venture.
If you intend to do some more mining you should next upgrade your ship. Once there you need to target an asteroid, fly within 10 km and then press the Miner I icon on your HUD. You are now mining ore if everything was done correctly and should see it appear after a minute in your cargo hold or ore hold if you have it on your ship. When everything is ready you can fit the Miner I module to your ship through the fitting screen, undock and fly to an asteroid belt in your current system. You can use your starting ship or any frigate you are currently flying but you need to train the skill Mining to level I before you can use the Miner I module. To be able to mine at the very beginning of the game you need access to a ship and a Miner I module.
