The new plan approved by the FS says water for drilling at Dog Bone Ridge will now come from Beaver Creek rather than Coral Creek. The agency also said Excellon has added several monitoring sites associated with Dog Bone Ridge.
We walked around for hours in amazement like little kids that just got let loose in a toy store without adult supervision.

Fast forward to present day and the XRF has come of age. Pull the trigger on the hand-held device and you get a nearly instant assay of the surface of a rock.
After paying for the mine fleet, mill capital, supplies, fuel, power and labor, at today’s metal prices, does this mine make a profit?
The proposed mine would be built on state-owned land in the Bristol Bay region, near the world’s largest wild sockeye salmon fishery.
A few months later, a young, greenhorn lawyer agreed to pay to have it assayed, and the quartz turned out to be rich in both gold and silver.
They… create negligible fumes and much less fly rock than blasting. Below are some tips on maximizing your effectiveness with these tools.
…let’s dive in and take a closer look at these rich gold and silver-bearing minerals to find out what they are, where they form, and how to identify them.
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
One of the first things we did while looking at buying the equipment was figuring out how it would dovetail into the milling process we already had in mind.
Many miners know that lead is very commonly associated with silver values, but the truth is that it is also associated with gold values in many locations as well.
