Have I Found A Solid Block Of Silver?

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.

Not yet, no news yet.
