Appia Initiates High-Resolution Ground

Gravity Survey at Alces Lake to Refine High-

Priority Drill Targets

Toronto, Ontario--(Newsfile Corp. - September 15, 2025) - Appia Rare Earths & Uranium Corp.

(CSE:

API) (OTCQB: APAAF) (FSE: A0I0) (MUN: A0I0) (BER: A0I0)

(the "

Company

" or "Appia") is

pleased to announce they have begun a high-resolution ground gravity survey on September 2nd, 2025,

at the Company's Alces Lake Rare Earth Elements (REE) project in northern Saskatchewan. This

geophysical program marks the next step in Appia's phased exploration strategy, building upon the

results of the 2024 Airborne Gravity Gradiometer (AGG) survey to refine multiple high-priority drill targets

at depth.

MWH Geo-Surveys Ltd. is currently conducting this high-resolution ground gravity survey, which aims to

refine a series of priority gravity anomalies originally identified during the 2024 Airborne Gravity

Gradiometer (AGG) survey conducted by Xcalibur Smart Mapping. These large-scale subsurface

features were processed and interpreted through 3D inversion modeling and are believed to represent

potential sources of monazite-hosted REE mineralization. The ground-based survey will provide

increased resolution and accuracy to assist in drill targeting for Appia's upcoming diamond drilling

campaigns.

Tom Drivas, President of Appia

, commented:

"This ground gravity survey is an essential step in our ongoing work to systematically refine and

prioritize our exploration drill targets at depth. By applying this high-resolution ground technique over

the strongest Airborne Gravity Gradiometer anomalies, we aim to maximize the efficiency and

precision of our planned drill campaign."

The high-resolution ground gravity survey at the Alces Lake Rare Earth Element (REE) property is

covering multiple gravity features (Figures 1 and 2) distributed along the regional fold and structural

corridor that hosts surface REE showings such as the high-grade WRCB zone, displaying such as 16.1

wt% TREO over 15.6 m including 49.17% wt% TREO over 3.7m in drill core (

refer to the 2019 press

release here

), and large Magnet Ridge zone, with mineralization open at depth. The program is

designed to better constrain the shape, depth, and density contrast of each target area, enabling Appia's

technical team to optimize drill collar placement and depth projections for their upcoming diamond

drilling campaign.
