Small Mining Operations
Who is a Qualified Person?
January 2012 by Thom Seal, PhD, PE
So you think you have an ore deposit? The work has been long and hard, but there are a few drill holes, lots of samples and assays. The data is in a reliable computer and there may be a mine at the end of the tunnel. What is the likelihood of a profitable operation? Can you raise capital for development or exploration?The Basics of Froth Flotation
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
Hard Work Pays Off On Hard Rock
They worked their plan, bit by bit, and sure enough, after the blast, gold was detected… Over two pounds of beautiful crystalline gold was recovered in that stretch!
Why Assaying Placer Gold Deposits Doesn't Work
Let’s set up a thought experiment: Suppose you had some material that ran one ounce per ton gold, which is generally considered high grade to fantastic grade depending on the circumstances.
Refractory Gold Processing
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.
Practical Advice for Milling Hard Rock Ores
The problem is that extracting gold from hard rock is often a lot more difficult than processing placer gravels. Still, there is some very high-grade ore out there in many old mining areas.
Reminder: Annual Claim Filings Due
Mining claimants who wish to retain their mining claims on Bureau of Land Management and Forest Service lands through the 2021 assessment year must pay a maintenance fee or file a maintenance fee waiver certificate on or before September 1…
Time to Stake Your Own Mining Claim
So let’s dive in and see what I can do to convince you that this is the year you should be out staking your own claims.
