Comparison Google Earth Vs Drone Imagery

Below: Identify ground disturbance, bags left on pad, access routes as well as incorrect GPS hole locations. Red circle indicates where the hole was drilled however the recorded GPS location (red dot) is showing the hole 25m further away in the wrong location. This is a common occurrence and something that is not often picked up on by many exploration companies.

Case Examples

1. Identifying Untested Quartz Veining
   High-resolution drone imagery revealed linear parallel quartz veining outcropping in an area that had not yet been rock chipped. A follow-up field excursion confirmed this discovery, returning some of the highest anomalous results seen in the program.

2. Correcting Drill Hole Coordinates
   Collar files, survey data, and geology were entered into Leapfrog, identifying a shear zone. However, georeferenced aerial mapping revealed that several drill hole coordinates were incorrect, as their plotted locations did not align with cleared pads. These corrections adjusted the shear zone's dipping angle, ultimately refining infill hole locations and planned drill depths.

3. Avoiding Inaccessible Terrain for Drilling
   A drill program with 50m spaced holes was designed from your Perth based office. Preliminary high-resolution drone mapping showed that many planned holes were located in steep, inaccessible terrain. Adjustments were made to optimize drill locations, saving time in the field. Later, when a gap in the drill data was noticed, a quick review of aerial imagery confirmed the location was inaccessible, leading to a new, feasible drill site.

4. Identifying Historical Work
   Your area has been previously explored and drilled. Accurate up to date imagery can identify existing tracks which can be beneficial for any PoW application. A lot of drilling occurred when GPS was poor or non-existent, however their ground disturbance remains to this day. A high-resolution map can help locate these old holes which can be important when drilling due to the potential of old hole activation.

5. Enhancing Investor Engagement
   Show investors a clear and compelling view of your project area using high-resolution imagery. A combination of flyover videos and geological snapshots can generate greater interest in your project.

6. Structural Interpretation for Mineralization
   Numerous faults and an unconformity run throughout your project, potentially acting as key structural controls for mineralization. High-resolution mapping helps accurately identify these critical geological features.

7. Minimizing Environmental Impact
   When working in environmentally sensitive areas, precise mapping enables track planning that avoids major bushlands and trees. A follow-up survey along the same flight paths can then document the actual impact, providing a valuable assessment of environmental impact

8. Field Navigation & Pegging with Georeferenced Imagery
   Clearing tracks and pegging drill holes can be streamlined using high resolution drone imagery. These maps can be uploaded into Avenza Maps, allowing field teams to navigate efficiently to areas of interest.
