NEW INVERSION DATA REVEALS SIX ANOMALIES AT AURANIA'S AWACHA TARGET

Reprocessing mobile magnetotellurics (MobileMT) data from Aurania Resources Ltd.'s Awacha porphyry copper target in Ecuador using the latest 2-D inversion technology has revealed six highly conductive anomalies.

In 2021, Aurania contracted Expert Geophysics Surveys Inc. to conduct a MobileMT airborne survey over the Awacha porphyry copper target area. At that time, electromagnetic (EM) data inversion was performed using a one-dimensional (1-D) algorithm. In recent years, EM inversion technology has significantly improved, particularly for areas with rugged terrain. As a result, Aurania recommissioned Expert Geophysics Surveys to reprocess the existing MobileMT data using the latest 2-D inversion technology. The 2.5-D code applied is more objective and comprehensive than the previous 1-D technology as it takes into account the actual topography of the area being investigated, yielding robust lateral and vertical resolution, resulting in more accurate mapping of the subsurface conductivity.

The new inversion data have confirmed the presence of six high-conductivity anomalies. These conductive anomalies typically begin 250 metres from the surface and exhibit deep roots. These anomalies are significant since zones of elevated conductivity often correlate with porphyry copper deposits due to the presence of electrically conductive sulphide minerals (pyrite, chalcopyrite and bornite) and porphyry-related alteration (phyllic and argillic zones).

The new MobileMT 2.5-D inversion results will be integrated with data and field observations from the Anaconda mapping program that was completed at Awacha in 2024. Aurania has engaged porphyry copper expert Dr. Steve Garwin, a senior technical adviser (see press release dated April 19, 2022), to review the Anaconda mapping data to identify the most promising porphyry targets at the Awacha area. Dr. Garwin's report and recommendations are expected in the coming weeks.
