Metalworking in a blind society

In my first major post about my all-blind society, I talked about possibilities for metalworking, and decided that bronzeworking seemed plausible but ironworking didn't really. For that, though, I was only really thinking about the last stage of the metallurgy process - how you turn bronze or iron into a finished object. To really make use of metal, you need more than that - you have to get the metal in the first place.

( Native metal vs. ore )

So, considerations of potential metals for use:
Iron:
Ore is abundant, but possibly hard to identify.
Blacksmithing iron is probably not plausible without vision - requires precise aim at objects too hot to touch.
Needs extremely hot temperatures for casting - likely not plausible.
Meteoric iron is easily findable if you're lucky enough to have a good large meteorite around.
Meteoric iron can to some degree be worked cold. Hitting cold objects that you can feel ahead of time to get a spatial model seems more plausible than blacksmithing.

Copper:
Ore is reasonably common, but possibly hard to identify.
Native copper does occur, and is probably easy to recognize, but possibly hard to find.
Can be cast at reasonably accessible temperatures - a technique that seems plausible without vision.
Can also be worked cold, through hammering and annealing.
Not very strong when not alloyed to make bronze, but still strong enough to be useful for tool-making.

Bronze:
Needs tin (or some other metals, but tin is preferable) as well as copper.
Tin ore is not very common, and also may be hard to identify.
Stronger than copper.

Gold, silver, electrum:
May be around in native format, but what would you use them for if you weren't using them for their appearance in decorative objects?

Lead:
I'm kind of ignoring it, but maybe I shouldn't. It needs ore identification, though, since it doesn't often occur native. It's relatively easy to extract. It melts at a rather low temperature, which is convenient. Of course it creates health issues, which may not be recognized.

I think I am going to say that they do not have access to tin, and therefore do not have bronze. And I don't think they make use of ores. However, I think I will say that they have a large iron meteorite, which they use for cold-worked tools. And there is native copper around, if they can find it; they probably find at least some of it, though I'm not sure in how great of quantities. They likely cast copper as well as cold-work it. But they likely still use stone tools as well.

It may be that this is only in the early period of their society, and that at some point they do figure out how to identify and smelt ores. I think they still won't have access to tin, though.
