Okay, I had another mining run this morning trying to concentrate a bit more on being efficient at money making and targeting more valuable metals/minerals.
I wrote down a lot of data while mining to try to get a feel for how lucrative each type of rock was and the estimated credits/hour when done. Here is a quick log that I hand wrote that may be helpful for others (17.6 ly from Orcus, Bhare system, A3 planet at a normal extraction site this time):
8:07am Dropped in at site from supercruise
8:08am found an Indite/Silver + Osmium rock. Passed on it.
8:09am found a Bertrandite/Gold rock. send in prospector to mine it. 28.88% Gold, 19.33% Bertrandite.
8:12am rock depleted and all fragments collected. Total of 6 Gold, 4 Bertrandite.
8:13 to 8:15am found rocks of Gallite, Silver/Bertrandite, Bertrandite/Gallite.
8:15am found a Painite/Bertrandite rock.
8:16am prospector sent, 34.97% Painite, 12.66% Indite, 6.16% Bertrandite.
8:19am rock depleted
8:20am all fragments collected and processed. Total of 10 Painite, 1 Bertrandite, 2 Indite
8:22am found a Painite/Gallite rock.
8:22am prospector sent, 43.48% Painite, 10.55% Gallite
8:25am rock depleted
8:26am all fragments collected and procesed. Total of 13 Painite, 3 Gallite.
8:27 to 8:30am spent time looking up items and deleting limpets and low cost items to make room (running 76 total cargo in an Asp).
8:30 to 8:31am two low quality rocks.
8:32am found an NPC miner and checked out what they were mining. Only <6% each of Gallite/Silver/Gold. No thanks!
8:33am found another Painite rock, Painite only this time.
8:34am prospector sent, 46.36% Painite.
8:38am rock depleted.
8:39am all fragments collected and procesed. Total of 15 Painite.
8:41am Head for home to Tombaugh Station in Orcus. This is one jump at 17.6ly. I upgraded to the B FSD so I can get to a 20 jump range while fully laden. Otherwise, pretty much using conVurt’s build just above and comes in around 11.7 million total.
8:46am Docked at Tombaugh.
My total haul was:
6 Gold
38 Painite
1 Bertrandite
1 Gallite
(I destroyed the Indite and extra Bertrandite and Gallite)
I turned in one Painite for a mission for somewhere around 100k. I sold the 37 remaining Painite for 1,310,873 and a total of 1,375,110 including the Gold and the rest. While this may have been fortunate to find those nice rich Painite rocks, this was a return on 39 minutes of time from arriving at the field to returning home to station. I could easily see averaging 1-2 million in a nice fit Asp like this and a good metal rich field.
Heck, the one rich Painite rock that I depleted in 4 minutes netted me 460,577 alone so there is quite a bit of potential there. I am wondering if there is a different appearance to the rocks with different metals/materials in them. Here are a couple shots of the good Painite ones I found:
Painite rock 1
Painite rock 2
Some other observations:
Left with 35 limpets and only used maybe 10 on the trip. 20 is probably plenty to fill a cargo hold for a trip.
With 2 med lasers, you only use them maybe 25% of the time. Most of the time I wait for my limpets to go collect so could probably get away with 1 med laser although it may take slightly longer to knock off that first chunk to test the rock and to knock off the first couple chunks. After that, I did a lot of waiting and not firing.
