I'm very interested to see what XRF results will show.

Oh that I was where I would be,
Then I would be where I am not,
Here I am where I must be,
Go where I would, I can not.

This quite educational....I had look up Babbitt metals

variants: or less commonly babbit metal
Definition of babbitt metal
: either of two alloys used for lining bearings:
a: a tin-base alloy
especially : one containing 2 to 8 percent copper and 5 to 15 percent antimony
b: a lead-base alloy containing 1 to 10 percent tin and 10 to 15 percent antimony with or without some arsenic

do you have a Geiger counter, I doubt it radio active but that if you want to be sure, does look like some sort of metal mostly likely a 8.5-8.95 g/cm3
Copper Nickel Alloy Properties (Theoretical).

had a quick search and it seems that Monel (Copper Nickel) it probably the most likely, since it looks to be refined metal and not just ore, usually made to resist sea water

where as tin 50% & lead 50% used in electronic Solder Alloy

Being a meteorite collector I can say 100% it's not a meteorite.

Looks like a chunk of Haematite to me.

The principal ore of silver is arcanthite, which doesn't look much like the ore sample pictured.
Pure arcanthite has a specific gravity of 7.3 but is normally found in association with other minerals.

Another ore that silver is found in, and commonly mined, is galena, which is a leas/zinc/silver combination. This ore has a cubic metallic appearance, so is does not appear that particular ore.

This is the link to a silver test solution that will also tell you what base metal it is if it is a base metal.

That's really an interesting find. It looks like a human made metal to me, but on the off chance it is a mineral, have you thought of performing a streak test or a hardness test?

Traditionally they use a piece of unglazed porcelain tile to scrape the mineral on, and note the color of the streak. Galena, I think is a gray streak, hematite is reddish or reddish brown. Sometimes you can just rub the specimen on a concrete slab or block.

For hardness, for example, can you scratch it with a fingernail? (probably not!) If not, can you scratch with a copper penny? (pre 1982) If not, with a penknife, a piece of glass, a piece of quartz, etc? That might tell you something.

Do you plan to go back and look for more?

The testing solution helped me identify a spoon that I always thought was silver (metal detecting find) to be made of nickel and lead.

Will be taking it to find out soon, had an incredibly busy few weeks. I will update when I have, I'm sure it won't be that exciting but you never know.
