=====Ore Security Class=====
{{:eve:industry:mining:asteroid.jpg?300|}}
----
=====Overview=====
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 can't find out
a system's security class directly in-game, but the value is present in the Eve database dumps.
In 0.0, 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.
----
=====Ores in 0.0=====
The security class is most useful in [[training:game_mechanics:system_security#null_security_space|0.0]] regions, since the whole region will have the same letter code, and the following number is then determined by the truesec of the system.
----
====Security Class Letter====
The following table shows the security class letter used for 0.0 regions:
^Class letter^Region^
^F|[[eve:region:Detorid]], [[eve:region:Cache]], [[eve:region:Insmother]], [[eve:region:Impass]], [[eve:region:Feythabolis]], [[eve:region:Tenerifis]], [[eve:region:Omist]]|
^G|[[eve:region:Stain]], [[eve:region:Esoteria]], [[eve:region:Querious]], [[eve:region:Paragon Soul]], [[eve:region:Delve]], [[eve:region:Period Basis]]|
^H|[[eve:region:Vale of the Silent]], [[eve:region:Tribute]], [[eve:region:Venal]], [[eve:region:Geminate]], [[eve:region:Deklein]], [[eve:region:Tenal]], [[eve:region:Branch]]|
^I|[[eve:region:Wicked Creek]], [[eve:region:Scalding Pass]], [[eve:region:Great Wildlands]], [[eve:region:Curse]], [[eve:region:Catch]], [[eve:region:Immensea]], [[eve:region:Providence]]|
^J|[[eve:region:Pure Blind]], [[eve:region:Syndicate]], [[eve:region:Fade]], [[eve:region:Cloud Ring]], [[eve:region:Outer Ring]], [[eve:region:Fountain]]|
^K|[[eve:region:Cobalt_Edge]], [[eve:region:Perrigen Falls]], [[eve:region:Malpais]], [[eve:region:Oasa]], [[eve:region:The Kalevala Expanse]], [[eve:region:Outer Passage]], [[eve:region:Etherium Reach]], [[eve:region:The Spire]]|

====Security Class Number====
And this table shows the relation between the truesec and the security class number:
^Class number^Truesec range^
^None| 0.00 — -0.25|
^1| -0.35 — -0.25|
^2| -0.45 — -0.35|
^3| -0.55 — -0.45|
^4| -0.65 — -0.55|
^5| -0.75 — -0.65|
^6| -0.85 — -0.75|
^7| -1.00 — -0.85|
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".

====Ore Class Letter====
This table shows the abbreviation used for Ore
^Ore Letter^Ore^
^V|Veldpsar|
^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|

====Ore Spawn Location====
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|
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.

=====Ores in Empire=====
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.
====Empire Security Letters====
The range of values found in the game are:
^Security class^Truesec range^Ores present^
^A|0.95 - 1.00|V, Sc|
^B|0.75 - 0.95|V, Sc, Py|
^B*|0.75 - 0.95|V. Sc, Pl|
^B1|0.45 - 0.75|V, Sc, Py, K|
^B2|0.25 - 0.45|V, Sc, Py, K, J|
^B3|0.00 - 0.25|V, Sc, Py, K, J, Hm|
^C|0.45 - 0.75|V, Sc, Pl, Py|
^C1|0.25 - 0.45|V, Sc, Pl, Py, K|
^C2|0.00 - 0.25|V, Sc, Pl, Py, K, Hd|
^D|0.75 - 0.95|V, Sc, Pl|
^D1|0.45 - 0.75|V, Sc, Pl, O|
^D2|0.25 - 0.45|V, Sc, Pl, O, J|
^D3|0.00 - 0.25|V, Sc, Pl, O, J, Hm|
^E|0.25 - 0.45|V, Sc, Pl, O, K|
^E1|0.00 - 0.25|V, Sc, Pl, O, K, Hd|
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.
