From the Official Docs
“Mining requires strength and endurance to excel at the art. It is hard manual labor, but that labor pays off. Visit the JEWEL mines to find JEWELs that were locked under the surface, or pay a visit to the gold mine if it pleases. Increasing a Hero’s Mining skill increases the yields that Hero will receive and allows the Hero to mine longer without a rest.
Mining is a passive activity that you send Heroes to do. A group of six Heroes can visit the mines at any time. Heroes gather rewards for every 12 minutes of Mining, as indicated on the Quest screen. Heroes with Mining as their main profession gather these rewards every 10 minutes instead, if the entire group are made up of miners. When the player stops the Hero’s Mining action, they will receive rewards based on how many full 12-minute (or 10-minute with Mining skill) periods were spent. Along with JEWELs or Gold, some have been known to find rarer treasures in these mines…”DFK Docs – https://docs.defikingdoms.com/learn/gameplay/professions

How Mining Works
Unlike other quest types, you can choose to send you hero to mine for Gold, or mine for Jewel.
When you mine for Gold, you’re effectively ‘creating’ gold tokens to add to the game. The factors that affect how much gold you get include profession gene, profession score and associated stats. For a nifty calculator to see how much your hero (or prospective hero if you’re scouring the Tavern) see here. It’s a long-assed formula and there’s no real need to know it if you can just type your hero ID into that nifty tool made by CryptoMeme and have the answers presented to you.
When you mine for Jewel, you’re unlocking locked Jewel that you already own (that you’ve claimed from the Gardens). Again, there’s a butt-tonne of maths involved but for Jewel, the optimal amount of locked Jewel to make mining for Jewel worthwhile is 3,333 LJ. There’s a great post written by Samichpunch here – there’s no point duplicating effort and writing it all out again. Or pretending like I understood any of it.
What You Need to Know
Any hero can be sent on the Level 0 Mining quest. But, like all profession quests, some heroes are better at it than others.
For instance, the most obvious advantage is to send a hero with the Mining gene:
For this quest, having the Mining gene means that your hero only takes 10 minutes on a quest per stamina spent. Heroes without the Mining gene take 12 minutes per stamina spent. So a new hero with the Mining Gene takes four hours and ten minutes to empty a stamina bar compared to five hours for a hero without the gene.
As mentioned in the general post about the Profession Quests, the Profession Score accounts for 2/3rds of the effectiveness of heroes at questing, with the correlating stats making up the other 1/3rd. For Mining, the two key stats are Strength and Endurance:
A hero with a blue stat in either Str or End means that the hero has an added chance of boosting those stats at each level, but if you have a hero that’s naturally got high Str/End then the blue/green/purple genes aren’t vital. They help, but there are heroes that are naturally better at some quests over others as their main primary stats coincide with specific professions:
As the Docs say, you can send heroes in groups of up to six at a time. With Mining, the duration of the time spent questing will always fall to the lowest common denominator. So, if 5 heroes have 25 stamina and one has 19, the group will only quest for 19 stamina. And if one of the heroes in the group doesn’t have the mining gene, it means the whole group will take 12 minutes per stamina spent rather than just 10.
You can also queue multiple groups that will start their quests automatically as soon as the previous group has finished.
For Jewel Mining, groups work a little differently. I’ll let the Docs explain:
“JEWEL mining quests require the player to select a lead miner. The maximum amount of JEWEL that can be unlocked in the quest is determined by the stats of the lead miner: the Hero’s STR and END scores, mining skill, and whether they have mining as their main profession all impact the max amount that can be unlocked. When a lead miner is selected, the maximum unlockable JEWEL for the party and the amount of JEWEL that can be unlocked by the lead miner alone will be displayed.
Up to five further Heroes can be added to the mining party to assist the lead miner. Their contribution to the party will be based on their STR and END scores, mining score and on whether the Hero has mining as their main profession. As individual Heroes are added to the party, the total amount of JEWEL that the party can unlock will update. Once the group’s total unlockable amount reaches the maximum unlockable amount, adding further Heroes will not increase JEWEL rewards further, although those Heroes can still receive Gaia’s Tears, Shvās runes, and Yellow Eggs.”https://docs.defikingdoms.com/learn/gameplay/professions/jewel-mining
Here’s an infographic detailing the loot available for each of the Level 0 Profession quests along with the chances of these items dropping in a quest. The Gaia’s Tears and and Shvas Runes have a ranged drop rate – the higher drop rates are for heroes with the right profession gene and the lower rates are for heroes without.
For Jewel Mining
“Additionally, for every 15 Stamina spent by the lead miner, there is a 10% chance to receive bonus JEWEL. The maximum bonus is 10 JEWEL, if the wallet has at least 5,000 locked JEWEL. The bonus scales down linearly if the wallet has less than 5,000 locked JEWEL. This bonus is halved if the lead miner does not having mining as their main skill.”https://docs.defikingdoms.com/learn/gameplay/professions/jewel-mining
We now have the XP formula for Mining:
Experience gained = 4*ticCount + 8*floor(ticCount/5) + 10*SuccessfulTearRolls + 30*RunesFound + 100*EggsFound
So effectively you get XP just for questing before you find any loot items (Tears, Runes, Eggs etc), but then you can get more XP based on what items you loot as well. Here are the loot items again with the amount of XP you get listed below:
