Quoting yourself:
Perusing your code 'cause I'm nosy, saw an issue:

I noticed on autoplace menu some icons are off (sulfur) and angels infinite ores show the dear auld icons, so....

In entity.ores.ores-updates.lua

--[[
local ores = {
-- Pure Bob's
"ground-water",
"lithia-water",
"lead-ore",
"rutile-ore",
"sulfur",
"thorium-ore",
"tin-ore",
"bauxite-ore",
"cobalt-ore",
"gold-ore",
"nickel-ore",
"quartz",
"silver-ore",
"tungsten-ore",
"zinc-ore",
}

for _, name in pairs(ores) do
-- Check for autoplace controls, skip if it does not exist
local control = data.raw["autoplace-control"][name]
local control_infinite = data.raw["autoplace-control"]["infinite-" .. name]
if not control then goto continue end
if not control_infinite then goto continue end

-- Setup rich text localized name
control.localised_name = {"", "[item=".. name .."] ", {"entity-name.".. name}}
if mods ["angelsinfiniteores"] then
    control_infinite.localised_name = {"", "[item=".. name .."] ", {"entity-name.".. "infinite-" .. name}}
end

-- Label to skip to next iteration
::continue::

end
--]]

Changing the source image for rich text from entity to item fixes the issue.
BTW these few lines of code helped me a lot in understanding how for loops work, thanks man

This is probably out of scope for this mod, and should be handled in reskins-angels, but the Angels dev branch already sets up these icons. I'll see what needs doing.

Not really, as you wrote in the comment "pure bob" many people plays pure bob plus infinite ores, i use the angel dev branch myself (0.9.9), though it uses the base bob low res icons

I actually need to do something different for this, I need to properly reskin Infinite Ores, lol.

LOL, how it comes? I did some testing and the icons on the autoplace menu look fair if the source is item rather than entity, also i didn't notice any difference in-game between finite and infinite entities tbh (nor that i even looked for any xD)

They're using Bob's sprites for the ores (and then have a really clumsy glow layer on top of it):

So technically speaking the icons are correct for what's there... :D

I'm thinking this will go in reskins-compatibility rather than reskins-angels.

LOL!!! That's messed up!
Yh i agree with you, compatibility would be sweet as it won't confuse non-angelbob users
