Screenshots of core rocks next to non-core rocks.

Been seeing several threads the last few days regarding how you tell which rock is worth using a prospector on. Took a couple screenshots while out mining today, maybe this'll help someone.

Void Opal core in front of a non-core rock:

Useful resource. Lots of people have a hard time recognising the most wanted rock in the verse. Here’s my paltry contribution:

Btw OP, you could have made more from that load.

Yeah but my Python was loaded down with rocks and I didn't feel like jumping twice as far for a 30,000 increase in payout. Thanks for the images, if anyone has any others to add, I'm sure people would appreciate the contributions.

Yeah for sure and nice job you’ve done here. Recognising the rocks is likely the biggest challenge to Core mining so having some reference images is really helpful.

The non-core rock on the right looks brighter yellow to me than the grandidirite core rock on the left, so this didn't help at all. I'll have to keep prospecting anything that looks even remotely yellowish.

It’s not that. The shape and size of the rock matters too. You need to discern which rock has a core that can be cracked from not only the specifics of how it glows, but also the shape and size of the rock. It’s really quite helpful to look carefully at the OPs images.

It's not the brightness you're looking for, it's the darkness. Notice the amount of black pixels on the core rock compared to the non-core rock. I should have gotten some long-range shots. I will try to do that tomorrow morning after work. At long range, the core rocks will appear brighter than a non-core but it can be hard to tell. As you get closer (repeating the pulse scan as you do so), you'll see that black "net" appear on the core rocks.

You need to keep at it using your own eyes and monitor and develop the experience to identify them. Don’t worry about other peoples images. I’ve seen cores that don’t match any of those. The only thing I started mining with was the FD training video and in a week of mining I can pick them out fine in icy and rocky. I still get false positives though. Sometimes the brightest one isn’t a core, just heavy in some mineral.

Cruise around, look for bright rocks. Get closer, are they still really bright? Any wierd pattern pop in when you scan it a few times? Shoot a prospector at it. Is it a core? If yes, then turn on your lights and get a look at the fissures. Note the appearance, use that as a visual later to not need a prospector.

I burnt a lot of prospectors starting out, but that’s a game learning curve. Every trip gives you that experience to get them. Keep at it.

I also notice that most rocks shift color shortly after the pulse scanner highlights the minable rocks. Core asteroids get brighter and more yellow on the color shift. Non core ones get dimmer. Core asteroids also have a granier texture with dark pixels on the initial highlight.

The core asteroids have a specific shape to them and are mid-sized. They are round and lumpy and appear to be a group of smaller rocks that have formed a mass. There are two oval shaped ones with a layered linear pattern. Those are a instant pass no matter what the pulse scanner shows.

I've had success by flying towards any round rocks that are highlighted at a distance by the pulse scanner. When it gets a little closer you can tell if it is a core or not by the intensity of the highlight and the more yellow hue.

That's why I'm asking folks to share screenshots of core rocks.

Everyone has their own suggestion for what you have to look for. Ideally, with a larger sample group, we can pick out exactly what distinguishes these rocks and get a better answer for people.

Exactly!

Thought I was getting the hang of this yesterday (after several hrs) but today, nada. Nothing I tag, however bright, bumpy or black netted (or not) is core.

Suspecting it's pure RNG.

Excellent OP, repped.

I thought I'd sussed out which rocks were cores, until I went to a metallic ring!

Personally I find metallics are harder to differentiate and the fractures are harder to spot. I'll try and get some screenshots later.

Nah you really do start to recognize them after a while but there are empty patches on the field with a lot of close but no cigar lookalikes. Hence this thread.
