Harvest numbers and XP

Normal veins yield 2–3 ore. Clean strikes reduce the work and increase XP without adding ore. A glint hit counts for two strike points; swings must be at least 0.45 s apart.

Node tier	Strike points	Swings if all are clean
1–2	4	2
3–4	5	3
5–6	7	4

Ore	Tier	Rank	Base XP	Clean XP	Quarter XP from rank
Iron	1	0	15	22	40
Tin	1	0	15	22	40
Copper	1	0	15	22	40
Lead	1	0	15	22	40
Sulphur	1	0	15	22	40
Lodestone	2	10	30	45	55
Mercury	2	10	30	45	55
Silver	3	25	45	67	70
Gold	4	40	60	90	90
Platinum	5	55	75	112	Never
Moonstone Ore	4	40	60	90	90
Dwarven Scrap	4	40	60	90	90
Mithril Ore	5	55	75	112	Never
Adamantium Ore	6	70	90	135	Never
Ebony Ore	6	70	90	135	Never
Orichalcum Ore	6	70	90	135	Never

Quarrying uses tier-1 XP:

Mining rank	Base XP	Clean XP
Below 40	15	22
40 or higher	3	5

Rule	Conversion	Condition
Quarrying a boulder	2 Rough Stone per Cut Stone	Clean act or Surveyor
Mason’s bench with Quarryman	1 Rough Stone per Cut Stone	Bench perk only

A boulder normally yields 3–5 Rough Stone. Quarrying converts that yield rather than adding 50% more stone; fractional Cut Stone is rolled as a chance.

Gem rolls require witnessed ground or a dungeon. A vein gives at most one gem.

Perk	Gem chance per glint hit
None	3%
Prospector	3.3%

A clean tier-1 or tier-2 vein has two separate rolls. Region and climate determine the gem type; dungeon gems are Diamonds.
