I am a geology student with a focus in mineralogy. It's impossible to know for sure what your particular mineral is, but it looks like galena, hematite, or bornite. The lighting in the pictures makes it look like it has colors so it's hard to identify it from the pictures.

If it's galena, it will be pretty heavy and super shiny.

Most hematites specimens I have in my collection are very smooth with no particular shape, but do not have any holes or dent-like markings.

If it's bornite, then it will will shimmer when you turn it in certain lights (like sunlight). It will have specks of blue, green, purple, and gold. It is nicknamed "peacock ore" because it reminds you of the color on the tail of a peacock and have those same flourescing colors.

The best I can tell from your pics that's rainbow Bornite, like someone else suggests.
Super lustrous and colourful? Only natural light captures the color?
Nice natural piece, glad it found you

I did a google image search and it looks nothing like any of the images for bornite.
