Drones provide the ability to map the ground with a single set of boots on the the ground, accurately, easily and completely non invasive. Not a single drill hole, or even shovel full of samples taken. The Forest Service has confirmed Homeland's statement last week that they have received permits to use drones to map Cleopatra (18 miles SW of O'Brien), and Red Flat (15 miles inland of Gold Beach) with magnetometers and lidar drones. Likely a 3rd party survey company will be hired, the FS has confirmed that they are not providing the surveys.
Magnetometers have been used by geologists and surveyors for a long time, mounted on backpacks and helicopters, and more recently mounted on drones. Magnetometers measure the amount of magnetic or ferrous material compared to the surrounding area. The maps on the top row of the picture shows 3D models of deposits in an area, warm colors representing deposits, cooler colors show less or no metallic material. This allows volumes of minerals/metals to be calculated accurately, and pinpoint where deposits are located. Information is gps tagged and easily overlaid onto a base map of the area.
Lidar has been around for years, and is available on a variety of sites to explore bare earth topography. ( Images in lower right corner) There are lots of layers to fiddle with the shading, trees, etc. In Oregon, my go to site is : https://gis.dogami.oregon.gov/maps/lidarviewer/
The details that a drone with a lidar camera can capture is so much more- including heights of the trees/structures, depth of canyons, with color 3D model capabilities.
As prospecting is ever evolving, there are a plethora of companies and startups that are providing drone services for the miners, both for the small scale independent miner to full industrial scale world mining market. From mapping claim boundaries, discovering old workings not found on foot, or even poking in tunnels to make safety assessments, drones are becoming indispensable. If you use a drone on your claim, what do you find most useful?
