I'm new to ED and gaming for that matter. I've been playing for about a week now and I have started to mine. Yesterday I made about 26mil CR mining with a Cobra III, small payload forces you to leave before NPC Pirated get interested. But I was wondering, the hot spot I'm in it seems I have to search and search for the core deposits I'm after. So it got me wondering if an area gets mined out? I tend to find a core deposit of VO, LTD, etc typically in 30-45 mins of searching. Is this normal, or is my deposit about mined out?
