All the Gold Ever Mined...
If you have been prospecting for any length of time, then you have probably heard something like, “All the gold ever mined would equal a cube 60 feet on each side.”
Our Readers Say

Gold Placers of the Kenai Peninsula, Alaska
The biggest obstacle is that like many streams on the Kenai Peninsula, high water during the summer months from snow melt and rain can make dredging nearly impossible. The best dredging is in the colder months of the year.
What Are Those Rocks In My Pan?
The placer mineral identification key is designed to answer this question. It attempts to recognize all the minerals in your gold pan concentrates.
Northwestern Alaska Mineral Resources
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
Understanding and Prospecting Benches
The most obvious benches are usually near the valley floor, but they can be thousands of feet above the valley floor. Since benches were made by streams, they can contain placer deposits.
Conrey Dredge No. 4—Part II
These were the men who periodically picked up the gold amalgam from the tables and sluices in the dredge, processed it, and transported the gold ingots to the railroad express office in Alder. Their trustworthiness must have commanded a prominent wage.
