If you want to be part of Ship Miner’s Steam Playtest, you can join by pressing the button at https://store.steampowered.com/app/3113690/Ship_Miner/ that looks like this:

I will add more and more testers overtime. If you request access and get the chance to be part of this Playtest, please also join Discord and/or fill the Feedback Form from within the game, your opinion means a lot, and will help me making the best possible game I can.

By the way, if you join the Discord and write to me I could also give you a Playtest key directly to be sure you have access to the game.
