Duval Mining Corporation? (research)

I had to change this from the original posting as I found new information. Appearantly Duval mining corporation did the core drilling I was asking about.
Weird thing is though they hold two patented claim in skamania county and are supposed to be an important mining company having some historical association with pennzoil I cannot find a single listing for them on google, like maybe the company has been scrubbed from the internet.

Can anyone help on that one? Duval corp contact information?

looks like your on the right path, looking at historical documents they sometimes go by colorful names of the prospects or patents like "last hope" or "Dixie queen"
sometimes you have to open a lot of the old historical mine records and look for TRS or old maps
