As long as Mr. O is talking about treasures in Alaska, here is a newspaper article that will make a body drool! (you might have to open it and enlarge it, as the file size had to be shrunken down, it was too large.)
then you should see a view of the article clipping, which will probably still look too small - but if you click on it (the image) it should zoom in considerably. Alternatively, download the image and save it, then open it using your Paint program or a photo viewer, and use the enlarger in that program to read it. I hope this helps.
The exact area is not specified (naturally!) but was somewhere along the Tanana river.
You are probably correct amigo Army of 1, though you could use some deductive logic to help narrow down the area by the dates given, what areas around the Tanana river drainage were being actively prospected in that time period, and the mention of the Hudsons Bay Co men being there (rather strange considering) could help.
Good luck and good hunting amigok, I hope you find the treasures that you seek.
