Matrix2,
In a normal public company I would direct you to the SEC or SEDAR filings but in the case of Silverado there has been an filing in over two years. Link is in the intro to this page.
Also in the intro for this page there are links to the court pages, BLM and other sites. There is information there from time to time. As well we have included any contact numbers for the management that we find or are given, you can give that a try.
If you have time read some of the posts here, it will save you time searching all those sites or will direct you to the source documents, so that you may form your own opinion of the company.
P.S. If doesn't appear that the company sold the domain name. From what I could find online the company had let the domain registration payment fall into default and the name was open to sale. The site that sold it says "Premium Names" can be purchased for $495. But if you want Silverado.ca it can be purchased current for $30, then you would have the yearly registration fee.
Good Luck with you search.
