Aurania Refines Tatasham Target in Preparation for Drilling

Toronto, Ontario--(Newsfile Corp. - September 13, 2021) - Aurania Resources Ltd. (TSXV: ARU) (OTCQB: AUIAF) (FSE: 20Q) ("Aurania" or the "Company") reports on geophysical modelling that has refined the shape of the Tatasham target, a feature that has characteristics of a porphyry, a deposit type that contains over half of the world's copper resources. Tatasham is located near the western margin of the Company's Lost Cities - Cutucu Project area ("Project") in southeastern Ecuador.

Aurania's Chairman & CEO, Dr. Keith Barron commented, "Tatasham is the largest geophysical feature identified in the airborne magnetic survey that we carried out over the whole concession area in 2017. We subsequently covered the target area in the MobileMT survey completed earlier this year. We believe that our geophysical inversion contractors have made a breakthrough in the inversion of MobileMT geophysical data acquired in mountainous areas like the Project area. The 3D inverted MobileMT and magnetic data define a magnetic core that is approximately 3 kilometres in diameter that could be the central part of a porphyry which is partially enclosed by a conductive zone that could be due to the presence of sulphides - which is where most of the mineralization is located in copper porphyries. Now that the target shape has been refined by remodelling of the geophysical data, we're doing some final field-checking and are preparing to drill Tatasham this year in Q4."

Tatasham Target

The core of the Tatasham target is a magnetic cylinder 3km-4km in diameter that is partially enclosed by a conductive zone derived from a totally different dataset - MobileMT (Figure 1). This geophysical model is consistent with a magnetic porphyry at the centre with an adjacent sulphide-bearing conductive zone - where mineralization is typically located.

Drilling is planned for Q4, 2021. Details of the drilling, in terms of metreage and number of planned holes, will be announced in due course.

Details of the Geophysical Modelling

Original processing of magnetic data from the 2017 geophysical survey showed the Tatasham magnetic feature (negative reduction to the pole) having a diameter of over 10km - the largest in the Project area. Refined processing of the magnetic data by three-dimensional magnetic vector inversion has resulted in a better-defined, smaller magnetic feature that is 3km-4km in diameter. In addition, three-dimensional inversion of MobileMT data has refined the location of conductive areas that are consistent with geological data.

Modelling of the magnetic and MobileMT data was carried out by Geotexera Inc. of St. John's, Newfoundland, Canada.

Risks, uncertainties and other factors involved with forward-looking information could cause actual events, results, performance, prospects and opportunities to differ materially from those expressed or implied by such forward-looking information. Forward looking information in this news release includes, but is not limited to Aurania's objectives, goals or future plans, statements, exploration results, potential mineralization, the corporation's portfolio, treasury, management team and enhanced capital markets profile, the estimation of mineral resources, exploration, timing of the commencement of operations and estimates of market conditions. Factors that could cause actual results to differ materially from such forward-looking information include, but are not limited to, failure to identify mineral resources, failure to convert estimated mineral resources to reserves, the inability to complete a feasibility study which recommends a production decision, the preliminary nature of metallurgical test results, delays in obtaining or failures to obtain required governmental, regulatory, environmental or other project approvals, political risks, inability to fulfill the duty to accommodate indigenous peoples, uncertainties relating to the availability and costs of financing needed in the future, changes in equity markets, inflation, changes in exchange rates, fluctuations in commodity prices, delays in the development of projects, capital and operating costs varying significantly from estimates and the other risks involved in the mineral exploration and development industry, the effects of COVID-19 on the business of the Company including but not limited to the effects of COVID-19 on the price of commodities, capital market conditions, restrictions on labour and international travel and supply chains, and those risks set out in Aurania's public documents filed on SEDAR.
