Giant Mining to complete lidar survey at Majuba Hill

Executive Summary

• Giant Mining Corp. has contracted UAS Inc. to conduct a high-resolution underground lidar survey at its Majuba Hill copper-silver-gold project in Nevada.
• The survey, scheduled for completion in the first two weeks of April 2026, will map accessible historical underground workings to generate a 3-D digital twin for enhanced geological modeling and drill targeting.
• Results will directly support the company's previously announced up-to-10,000-foot core drilling program planned for 2026, focusing on testing deeper mineralized zones and areas beneath historical workings.

Key Details

• Contractor & Timeline: UAS Inc. (US-based team operating out of Montana) conducting fieldwork for completion during the first two weeks of April 2026.
• Survey Scope: ~3,000 feet of drifting in the Middle adit; ~169 feet of development in the Upper adit; network of historical stopes (one primary accessible); adits typically 6-8 feet high; narrow stopes averaging 30-40 inches wide; historical raises and winzes generally <50 feet high.
• Accessibility Limitations: Deeper winzes and potentially unstable/obstructed zones are currently inaccessible; lidar data requires integration with geological, geochemical, and drilling data and does not directly measure mineralization.
• Deliverables & Purpose: High-resolution 3-D digital twin to support structural interpretation, identification of historical mining orientations/controls, correlation with surface geology, and enhanced targeting beneath/adjacent to historical workings.
• 2026 Drill Program Integration: Lidar-derived 3-D models will refine drill collar locations for an up-to-10,000-foot diamond drill program targeting breccia-hosted and intrusive-related Cu-Ag-Au mineralization, extensions at depth, and zones beneath historical underground workings.
• Exploration Strategy: Parallel 2026 strategy includes AI-assisted geological targeting (supplementary only), integration of historical data, and surface exploration.
• Historical Context & QA/QC: Past operations by Freeport Sulphur Company (1940s); historical drilling QA/QC reviewed by Qualified Person E.L. (Buster) Hunsaker III, CPG 8137; no current mineral resource estimate exists and future resource delineation is uncertain.

Notable Quotes

• David Greenway, President & CEO: "The engagement of UAS Inc. to complete an underground lidar survey is intended to support the company's ongoing evaluation of the Majuba Hill project. The digitization of accessible historical underground workings, including areas explored by previous operators, is expected to provide additional spatial data to inform geological interpretation and exploration planning."
