Appia Rare hires Quantec for MT survey at Otherside

Executive Summary

• Appia Rare Earths & Uranium Corp. has engaged Quantec Geoscience Ltd. to conduct a Spartan magnetotelluric (MT) survey on its 100%-owned Otherside uranium property in Saskatchewan's Athabasca basin during Q1 2026.
• The survey will integrate with existing 2024 airborne gravity and magnetic data to map subsurface resistivity, highlight density contrasts, and outline lithological variations, ultimately defining high-confidence drill targets along a 49 km EM conductor trend.
• This MT survey represents the final major data set required to advance planning toward the next phase of drilling on the property.

Key Details

• Survey Contractor: Quantec Geoscience Ltd.
• Survey Type: Spartan magnetotelluric (MT) survey
• Timing: Q1 2026
• Location: Otherside uranium property, ~28 km south of Fond-du-Lac, Saskatchewan (Athabasca basin)
• Property Size: 10,422 hectares (100% owned by Appia)
• Target Feature: 49 km long, faulted electromagnetic (EM) conductor trend potentially prospective for Athabasca-style uranium mineralization
• Survey Objectives: Map subsurface resistivity to identify key faults and conductive zones; highlight density contrasts indicative of alteration and structure; outline lithological variations and basement trends
• Data Integration: Combined with 2024 airborne gravity and magnetic data and other datasets
• Survey Logistics: 84 MT stations spaced 200 metres apart; approximately 17 days of fieldwork; daily progress reports including preliminary 2-D inversion sections
• Strategic Context: Conductor trend comparable to features associated with NexGen Energy's Arrow deposit; property shares geological signatures with Uranium Energy Corp.'s Shea Creek and Cameco's Millenium deposits

Notable Quotes

• Tom Drivas, President: "The MT survey will provide the final major data set needed to define high-confidence drill targets along this extensive 49 km long conductor, advancing our planning toward the next phase of drilling."
