The National's rich early history was vividly captured by Nancy B. Schreier in Highrade: The Mining Story of National, Nevada. It's a really fun read.
The National includes the 6 patented Walker claims on which the original National Mine is sited, as well as the 8 famed patented Gliko claims that abut the Walker claims (and are historically significant producers in their own right). We have further added 14 lode and 2 placer claims to appropriate all of the nearby lands and historic dump piles that are of interest to us.
The cache of information our professionals have assembled on The National is downright astonishing. Here's a smattering of our historical, primary-source information that might interest you:
