Question about deep core mining yields.

[TheOofertaffy]

Whenever i'm mining, i go and put the sismec charge on the fissures. Once i get it into the blue PERFECTLY. no red what so ever. once i detonate it, at the 1-2 second before detonation, the yield goes into the red and says i got poor yield. Why does this happen. am i doing something wrong?

There is more to getting a good yield than getting the charges to register in the Blue Zone. The seismic charges work best when kept to a minimum number of overall charges as well, and over-charging them (ie. using a High Charge on a Low fissure) tends to give the results you mention.

So, here's the rules of thumb I've been working with:

(1) The absolute minimum number of charges that will commonly bust a Core rock open is Two. They will most likely be set inside of two Low Strength fissures, and you'll have to overcharge them.

(2) Using more than four or five charges will give the same results as in #1, but chances are you'll be adding Low Strength charges to push the indicator into the Blue.

(3) "Low Yield Forecast" doesn't always impact the actual yield. The absolute Best Case scenario for a Core rock is more than 16 tons (I've seen up to 20 tons from one rock); anything under 12 is the result of the explosion destroying the highest value fragments which are pushed out and around the chunks of rock, not the high value Surface deposits on the inside of the rock.

In short, then -- stacking too many charges or using too many High charges will likely start to destroy the fragments, and that's what the indicator is warning you about.

Ya i usually overcharge the explosives using 2 high on 2 lows and if i need 1 low on a high/average to nudge it into the blue. still get the low yield forecast.

The real question I'd have for you is, how many tons are you collecting after each Core you bust open? If it is less than 16, the indicator isn't only warning you of a probability of failure, but if you are getting 16-20, then it's probably a "false positive" warning.

You can also get the same result by "under-charging" a rock, by setting the charges at too low power. Then, the explosion doesn't bust the Core (perhaps a fragment or two will be spit out) but you'll be able to bust the Core with only a single charge afterwards, and the indicator will warn you that the yield forecast will be bad.... but it won't actually be. Count the tons you get, and use that as your metric.

o7 and happy busting, Commander!

OP it just happens sometimes: the only time you get "perfect yield" atm, is when it is maximum chunks. -been core mining for a while and got a bit confused abt it too.

It turns out that getting 12-14 chunks instead of 15+ is what triggers the "not optimal" msg.

i never actually gotten more then 15 surface deposits on the asteroid, however i believe some get actually blown out of the asteroid when you blow it up, but the hud tells me around 9-15 mostly 12-13 seems to be consistent for me. but if i count all of them together i'd say the most i get is 19 or so.

Count the actual tons you're getting in the Cargo Hold. The Fragments which get ejected are a Percentage of a Ton, and the same goes for the Surface deposits. When they've been processed, then you know exactly how much you've gotten.

In my experience, there are usually as many Surface deposits as fragments blown out of the rock (perhaps 11-12 of each) and that's why I know there's potentially 16-20 tons in total.

Totally aside -- Subsurface deposits are also super sensitive to explosives going off around them, so be careful when launching displacement missiles near fragments which are floating nearby. And, the best case scenario for a Laser rock (66.7% Platinum in a Metallic ring) is also an average of about 20 tons.

Old display bug, I get it on every pop even when I get 15 tons. Don't go by forecast, go by actual results. It's a dumb, confusing system that has gotten everyone at least once.

Good fortunes, potato hunter o7

TIL - jesus i've been getting this wrong for years, i've always put low charge on low strength, high charge on high strength.
