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

Toronto, Ontario, June 27, 2025 – Aurania Resources Ltd. (TSXV: ARU; OTCQB: AUIAF;

Frankfurt: 20Q) (“Aurania” or the “Company”) reports that reprocessing Mobile MagnetoTellurics

(MobileMT) data from the Company’s Awacha porphyry copper target in Ecuador using the latest 2D

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 (1D) algorithm. In recent years, EM inversion technology has significantly

improved, particularly for areas with rugged terrain. As a result, Aurania recommissioned Expert

Geophysics Surveys Inc. to reprocess the existing MobileMT data using the latest 2D inversion technology.

The 2.5D code applied is more objective and comprehensive than the previous 1D 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 has confirmed the presence of six high-conductivity anomalies as shown in Figure

1. These conductive anomalies typically begin 250 metres from the surface and exhibit deep roots as seen

in Figure 2. These anomalies are significant since zones of e levated 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 2.5D 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 Advisor (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.

Forward-Looking Statements

This news release contains forward -looking information as such term is defined in applicable securities

laws, which relate to future events or future performance and reflect management’s current expectations

and assumptions. The forward- looking information includes Aurania’s objectives, goals or future plans,

statements, exploration results, potential mineralization, the tonnage and grade of mineralization which has

the potential for economic extraction and processing, the merits and effectiveness of known process and

recovery methods, the corporation’s portfolio, treasury, management team and enhanced capital markets

profile, the estimation of mineral resources, exploration, timing of the commencement of operations, the

commencement of any drill program and estimates of market conditions. Such forward-looking statements

reflect management’s current beliefs and are based on assumptions made by and information currently

available to Aurania, including the assumption that, there will be no material adverse change in metal prices,

all necessary consents, licenses, permits and approvals will be obtained, including various local government

licenses and the market. Investors are cautioned that these forward-looking statements are neither promises

nor guarantees and are subject to risks and uncertainties that may cause future results to differ materially

from those expected. Risk factors that could cause actual results to differ materially from the results

expressed or implied by the forward- looking information include, among other things: 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; the inability to recover and process mineralization using known mining methods; the presence of

deleterious mineralization or the inability to process mineralization in an environmentally acceptable

manner; commodity prices, supply chain disruptions, restrictions on labour and workplace attendance and

local and international travel; a failure to obtain or delays in obtaining the required regulatory licenses,

permits, approvals and consents; an inability to access financing as needed; a general economic downturn,

a volatile stock price, labour strikes, political unrest, changes in the mining regulatory regime governing

Aurania; a failure to comply with environmental regulations; a weakening of market and industry reliance

on precious metals and base metals; and those risks set out in the Company’s public documents filed on

SEDAR+. Aurania cautions the reader that the abo ve list of risk factors is not exhaustive. Although the

Company believes that the assumptions and factors used in preparing the forward -looking information in

this news release are reasonable, undue reliance should not be placed on such information, which only

applies as of the date of this news release, and no assurance can be given that such events will occur in the
