Currently at the back of a mining ship it shows a circle that slowly fills up as you mine.
Perhaps look at replacing a floating circle at the rear of a mining ship to some visual actually on the ship. For example mining barges have 4 segments (like containers) Suggest change the strip on the side to be a LED indicator, as each quarter fills up have default green as empty, yellow as half full red as each quarter fills up.
Venture has 3 components which again can have the outer edge to change colour as each 3rd fills up.
