Ann: Drone magnetic survey at Mongoose completed, page-6

Application of drones to upgrade aeromagnetic anomalies

This intense aeromagnetic methodology was just applied at Mongoose prospect area at 30 metres height.

Selected slides from the CSIRO presentation:




Improved magnetic map detail of the survey by flying at smaller line spacings - regional 400 metre line spacing (left) versus 80 metre line spacing (right).




A comparison of the regional survey data (left) versus the detailed survey data (right image - higher resolution) for the "black boxed area" marked on the previous image above. The improved resolution can identify new mineral anomalies.



Inversion model of the 80-metre line spacing data (below) - illustrates the example anomaly is 39 metres below surface, average depth is 205 metres, vertical extent is 176 metres with an estimated volume of 5.3 x 10^6 cubic metres.



Therefore, I look forward to the data interpretation & modelling of the drone intense magnetic survey over the prospect.

This will better focus the drilling program of the Mongoose IOCG system planned for late September.
