I would tend to say copper, don't think bronze gets that blue green corrosion/patina. Don't know.

Here is an idea. What if its actually copper ore, meaning a natural rock with crystals of copper minerals in it.

The second photo does look like bits of copper are shining in it. Googling the ore photos, the green looks right on as well. But I'm not a rock expert.
 
Bronze can get a green patina, check older bronze statues.

Best is to file a notch to cut though the corrosion and see the base metals true color. Then you have a much better guess.
 
Good tips boys! I'll get a small drill bit and see what's inside

have you washed it more since the first photo? i am still going with the ore guess, be interested to see it clean before you start punching holes in it.
 
Hunk of Copper? Junk? Gold😜?

I cleaned and scraped the hunk of whatever I dug up. Now I'm even more intrigued. Please help me identify this object. It's approximately 1 in long by 3/4 width.
Thank you in advance.

Is the texture of it really like a rock or is it maybe a broken chunk of brass or something?

It would appear there was, in the early 1900's, a Bronze smelting operation in Meadville Pa. To me it looks like a piece of Bronze slag.
 
Brass and bronze both get the same patina as copper because they are both primarily made from copper..

Bronze will be slightly magnetic compared to brass or copper..
 
Bronze isn't smelted, it's an alloy of coper and tin..

The article I read referred to the combination of the copper and tin as smelting. I do understand the difference you refer to but apparently this process is still referred to as smelting.
Smelting bronze requires a forge. Allows the miner to smelt a tin bar and a copper bar together into two bronze bars. Smelting bronze requires a forge.

Google; smelting bronze.
