Precious Metal Miners / Royalty / Streaming companies

Hello,
I am new to the Precious Metals space and have been looking into things that are a store of value.

I am interested in finding out a lot more about the subjects of:

1. Stock to Flow,
2. Physical v's Paper silver,
3. Royalty companies.

Any ideas where on the internet the best resources are for these?

Thank you.

Here are some I have found

 

1. Crux Investor
2. Stansberry Research
3. Kitco News
4. Real Vision
