People are always interested in men, especially in successful men. This is the case with "Ike" Guker, the discoverer of the celebrated "Great Northern" mine in Grant County. He is a miner of considerable experience, having gained it in Colorado, Idaho and Oregon. March 28th, 1800, he began in this county, and just six months later he discovered his present property, which bids fair to make him famous. It is a placer property, although he has since located three permanent quartz ledges. His daily returns amount to $220,000 on an average.
