Hunting Tips and Safety

When hunting at the mine sites, you can be more productive by working in pairs—one person with a regular metal detector and the second person with the pinpointer—taking turns using the different devices.

We also suggest that you have a rock hammer and chisel for breaking off large chunks of rock so that you have less to carry, a water spray bottle and small wire brush to clean off your finds, a magnifying glass to inspect the specimens, and a backpack or bucket.

If you don’t have a metal detector, the green oxidization that occurs with copper is a great visual cue, as is a bright glow of orange. Hunting in sunlight will help you spot these variations.

The most critical safety concern is walking or climbing on mine-waste piles. These piles are prone to rockslides with sharp, jagged rocks that can cascade down and cause serious injuries. Hunting on old mine-waste piles also requires significant stamina, coordination, and even some upper-body strength for moving large stones. You’ll be carefully moving and tossing things aside or down the pile, either to allow your metal detector to send signals deeper into the pile or in response to a signal. You’ll also be kneeling on hard, rocky ground while hammering on rocks to break them and expose the copper inside.

Additionally, if you’re hunting with others, you’ll need to keep a safe distance when people are using picks and hammers, to avoid getting hit by flying rock shards or the tools themselves. A good pair of safety glasses is critical anytime you are breaking rock or are near others who are.

Additional safety considerations include wildlife (such as bears, mosquitoes, and biting flies) and staying hydrated and nourished.
