Toronto, Ontario – (Newsfile Corp. – September 13, 2021) – Aurania Resources Ltd. (TSXV: ARU) (OTCQB: AUIAF) (FSE: 20Q) (âAuraniaâ or the âCompanyâ) reports on geophysical modeling that refined the shape of the Tatasham target, a feature that exhibits the characteristics of a porphyry, a type of deposit that contains more than half of the world’s copper resources. Tatasham is located near the western margin of the Company’s Lost Cities – Cutucu Project (âProjectâ) area in southeast Ecuador.
Aurania President and CEO Dr Keith Barron commented, âTatasham is the largest geophysical feature identified in the aerial magnetic survey we conducted over the entire concession area in 2017. We then covered the target area in the MobileMT survey conducted earlier this year. We believe that our geophysical inversion contractors have made a breakthrough in inverting MobileMT geophysical data acquired in mountainous areas like the project area. Inverted and 3D magnetic MobileMT data defines a magnetic core about 3 kilometers in diameter which could be the central part of a porphyry which is partially enclosed by a conductive zone which could be due to the presence of sulphides – it is there that most of the mineralization is located in the copper porphyries. Now that the shape of the target has been refined by reshaping the geophysical data, we are performing final field checks and preparing to drill Tatasham this year in the fourth quarter. ”

A first description of Tatasham’s target can be found in a video (from minute 1:10) on our website titled “Metron Probability Update Part III – Making Sense of Our Magnetic Data“.
Target of Tatasham
The heart of Tatasham’s target is a magnetic cylinder 3-4 km in diameter that is partially surrounded by a conductive zone derived from an entirely different data set – MobileMT (Figure 1). This geophysical model is consistent with a magnetic porphyry at the center with an adjacent sulphide conductive zone – where mineralization is generally located.
Drilling is scheduled for the fourth quarter of 2021. Details of the drilling, in terms of the planned footage and number of holes, will be announced in due course.
Details of geophysical modeling
Original processing of magnetic data from the 2017 geophysical survey showed that the Tatasham magnetic characteristic (negative pole reduction) had a diameter of over 10 km – the largest in the project area. The refined processing of the magnetic data by three-dimensional magnetic vector inversion has resulted in a smaller and better defined magnetic characteristic with a diameter of 3 to 4 km. In addition, the three-dimensional inversion of the MobileMT data has refined the location of conductive zones that are consistent with the geological data.
Magnetic and MobileMT data modeling was performed by Geotexera Inc. of St. John’s, Newfoundland, Canada.
