Mining

The types of ore that can be found in a system's asteroid belts are determined by a code called the security class of the system. You cannot find out a system's security class directly in-game, but the value is present in the Eve database dumps. In null security space, you can deduce a system's security class from the region it is in, and the truesec of the system.

The security class is a letter from A to J, optionally followed by a number from 1 to 7. For example, Jita is a class "A" system, and S-U8A4 is class "J2". Generally, the higher the number, the better the ore. All security classes are viewable on dotlan via the filters on the region maps.

Ores in empire space

Security class letters A-E are used in empire regions, and systems in the same region may have different letter classes, which makes them less useful. The range of values found in the game are:

Security class	Truesec range	Ores present
A	0.95 to 1.00	V, Sc
B	0.75 to 0.949	V, Sc, Py
B*	0.75 to 0.949	V, Sc, Pl
B1	0.45 to 0.749	V, Sc, Py, K
B2	0.25 to 0.449	V, Sc, Py, K, J
B3	0.00 to 0.249	V, Sc, Py, K, J, Hm
C	0.45 to 0.749	V, Sc, Pl, Py
C1	0.25 to 0.449	V, Sc, Pl, Py, K
C2	0.00 to 0.249	V, Sc, Pl, Py, K, Hd
D	0.75 to 0.949	V, Sc, Pl
D1	0.45 to 0.749	V, Sc, Pl, O
D2	0.25 to 0.449	V, Sc, Pl, O, J
D3	0.00 to 0.249	V, Sc, Pl, O, J, Hm
E	0.25 to 0.449	V, Sc, Pl, O, K
E1	0.00 to 0.249	V, Sc, Pl, O, K, Hd

V = Veldspar, Sc = Scordite, Py = Pyroxeres, Pl = Plagioclase, J = Jaspet, K = Kernite, O = Omber, Hm = Hemorphite, Hd = Hedbergite.

• Note: "B" class systems in Gallente space (shown as "B*" here) have Plagioclase, instead of Pyroxeres. They should probably be flagged as "D" class, but aren't shown this way in the database.

This table shows the system security classes present in each empire region:

Region	Security Class
Tash-Murkon, Domain, Kor-Azor, Genesis	A, B-B3
Derelik, Devoid, The Bleak Lands, Khanid, Kador, Aridia	B-B3
The Forge, Lonetrek	A, B, C-C2
The Citadel	A, B, C, C1
Sinq Laison, Everyshore, Essence, Verge Vendor	A, B*, D1-D3
Solitude, Placid	B*, D1-D3
Heimatar, Metropolis	A, D, D1, E, E1
Molden Heath	D, D1, E, E1

Ores in null security space

The security class is most useful in null security regions, since the whole region will have the same letter code, and the following number is then determined by the truesec of the system.

The following table shows the security class letter used for null security regions:

Class Letter	Region
F	Detorid, Cache, Insmother, Impass, Feythabolis, Tenerifis, Omist
G	Stain, Esoteria, Querious, Paragon Soul, Delve, Period Basis
H	Vale of the Silent, Tribute, Venal, Geminate, Deklein, Tenal, Branch
I	Wicked Creek, Scalding Pass, Great Wildlands, Curse, Catch, Immensea, Providence
J	Pure Blind, Syndicate, Fade, Cloud Ring, Outer Ring, Fountain
K	Cobalt Edge, Perrigen Falls, Malpais, Oasa, Kalevala Expanse, Outer Passage, Etherium Reach, The Spire

And this table shows the relation between the truesec and the security class number:

Class number	Truesec range
None	0.00 to -0.249
1	-0.25 to -0.349
2	-0.35 to -0.449
3	-0.45 to -0.549
4	-0.55 to -0.649
5	-0.65 to -0.749
6	-0.75 to -0.849
7	-0.85 to -1.00

For instance, Syndicate has a security class letter of "J", and S-U8A4, with a truesec of -0.446, thus has a security class of "J2".

The actual ores which will spawn are given by this table:

Security Class	F	G	H	I	J	K
Base	V, Sc, Hd, Hm, O	V, Sc, Pl, O, K	V, Sc, Py, Hm, J	V, Sc, Hd, Hm, O	V, Sc, Py, Pl, J	V, Sc, Hd, Hm, O
1	Sp	G	Hd	J	DO	DO
2	G	Py	DO	Sp	C	Sp
3	B	Sp	K	G	B	C
4	A	B	C	DO	Hm	B
5	Py	C	Sp	A	Hd	A
6	M	M	M	M	M	M
7	Pl	DO	B	K	A	G

V = Veldspar, Sc = Scordite, Py = Pyroxeres, Pl = Plagioclase, J = Jaspet, G = Gneiss, K = Kernite, O = Omber, DO = Dark Ochre, C = Crokite, B = Bistot, M = Mercoxit, A = Arkonor, Sp = Spodumain, Hm = Hemorphite, Hd = Hedbergite.

• Note that, going down each column, all ores present in the class above also spawn. For instance, "J" systems spawn Veldspar, Scordite, Pyroxeres, Plagioclase, and Jaspet. "J1" systems have all of those, plus Dark Ochre. "J2" systems have everything in "J1" systems, plus Crokite, and so on.
