Several Exploration Targets Defined From Drone Magnetic Survey At Madison Copper-Gold Project

VANCOUVER - American Pacific Mining Corp announced a recently completed Unmanned Aerial Vehicle (UAV) Drone magnetic survey over the Madison Property. A total of 344 line-kilometers (km) of UAV magnetic data was compiled at a line spacing of 25 meters (m) and 50m over an area of approximately 11.34 km². Prior to the magnetic survey, a UAV orthophoto survey was used to create a digital elevation model to guide the subsequent magnetic survey. Drone surveys are recent innovations that provide extremely detailed data not available from the more traditional helicopter or fixed-wing aircraft surveys.

President, Eric Saderholm, said, “We are very pleased with the results of this exceptional quality magnetic survey and the expanding exploration targets that are developing at Madison as a result. The newly defined magnetic high anomalies are much more pronounced than expected and are interpreted by American Pacific geologists as the late-stage intrusions that are essential to any copper-gold porphyry and skarn system. These anomalies are often responsible for the strongest gold and copper mineralization in these types of systems and the number of untested targets generated by this survey is suggestive of property-wide exploration upsides remaining at Madison.”

The strength of the magnetic highs (pink shapes highlighted in Figure 1 below) highlight additional exploration targets located well to the west and southwest of the current drilling programs. The blue shaded anomaly on the flanks of the northern magnetic high is also of interest, and American Pacific geologists interpret this as alteration associated with a potential intrusive body hidden under cover. The presence of this not yet drill-tested magnetic low is highly encouraging and provides an additional exploration target to consider testing in subsequent drill campaigns. The pronounced band of pink magnetic highs to the south suggests structurally controlled intrusions or dikes that may be associated with visible gold found in samples collected by Kennecott Exploration (KEX) geologists earlier in 2021.

The orthophoto survey was conducted with a Wingtra One PPK VTOL mapping drone. Ground control targets were laid out and the positions surveyed before the photo mapping.

The MWH-UAV magnetic system uses a Geometrics MagArrow Cesium Magnetometer operated in conjunction with a Watts Innovation Prism X8 axial quadcopter. The MagArrow sensor takes 1000 readings per second and is flown at a maximum speed of 12 m/second. The sensor is suspended on a 2.5m lanyard to remove it from the electromagnetic noise of the UAV. Data is down sampled after collection to 10Hz. The MagArrow readings are diurnally corrected via a Geometrics G858 base mag, cycling at 10 readings per second.
