On March 27, 2026, Giant Mining Corp. announced an engagement with Unmanned Aerial Services Inc. (UAS Inc.) to perform a detailed underground LiDAR survey at the Majuba Hill Copper-Silver-Gold project in Pershing County, Nevada. The field team, operating from Montana, has scheduled work to be completed during the first two weeks of April 2026. The program is positioned as a technical step to convert legacy underground development into a modern spatial dataset that supports geological models, structural interpretation, and upcoming drill planning.
The primary aim is to digitize accessible portions of historical mine workings, including drifts, adits and stopes created by earlier operators such as Freeport Sulphur Company. Giant Mining’s leadership expects the new spatial information to be integrated with existing maps, historical drill data and geophysical results to sharpen the focus of a planned up to 10,000-foot core drilling program. Management has emphasized that the LiDAR dataset will inform, but not replace, conventional geological interpretation in the search for deeper mineralized zones.

LiDAR scope and technical objectives
The survey will target a mix of accessible openings: roughly 3,000 feet of drifting in the Middle Adit, about 169 feet of development in the Upper Adit, a primary stope suitable for scanning and a series of adits and narrow stopes. Typical adit dimensions are noted at 6 to 8 feet in height while some stope openings average 30 to 40 inches in width; several raises and winzes under 50 feet are also expected to be mapped where safe access permits. Certain deeper or obstructed winzes may remain inaccessible, which will limit complete coverage.
Expected deliverables and limitations
UAS Inc. intends to produce a high-resolution digital twin of the mapped workings that can be used for structural interpretation, orientation analysis of historic mining, and correlation with surface geology and drill holes. The Company is also evaluating future photogrammetry campaigns to complement LiDAR. Users should note the inherent constraints: underground scanning is impacted by line-of-sight issues, physical access restrictions and potential data gaps. Importantly, LiDAR yields geometric information only and does not directly measure mineralization, so results must be combined with geochemical and drilling data for exploration targeting.
Integration with drilling plans and historical context
Majuba Hill contains extensive historic development and past production with drilling completed by previous operators including Freeport Sulphur Company in the 1940s. Giant Mining plans to use the LiDAR-derived geometry to better target zones beneath and adjacent to these workings, supporting deep holes designed to test newly identified breccia-hosted and intrusive-related targets. The broader 2026 exploration strategy comprises drill testing, surface work and AI-assisted targeting that is being applied as a supplementary data tool rather than a substitute for conventional geological evaluation.
Drill program specifics and expectations
The announced drill program contemplates up to 10,000 feet of diamond drilling focused on extensions of known mineralization and deeper targets beneath historical underground development. Integration of the LiDAR models with existing geophysical and geological datasets aims to refine collar locations and reduce uncertainty in target definition. Giant Mining reiterates there is currently no mineral resource estimate for Majuba Hill and that further exploration is required to determine any resource potential.
Project attributes, QA/QC and UAS Inc. profile
Majuba Hill covers approximately 9,684 acres and sits about 113 road kilometers southwest of Winnemucca and 251 kilometers northeast of Reno, accessible via maintained county roads. The property benefits from nearby roads, power and water infrastructure that management says offers logistical advantages. Historically, roughly 89,395 feet of drilling have been completed at Majuba Hill with an estimated replacement value of about USD $12.1 million. The system shows open-ended potential, and the Company states it is fully financed for the next phase of drilling.
Quality control and technical oversight
Historical analytical work referenced was completed by ALS USA Inc., an ISO/IEC 17025 accredited lab, and earlier programs included insertion of certified standards, blanks and duplicates. These historical QA/QC records were reviewed by the Company’s Qualified Person, E.L. “Buster” Hunsaker III, CPG 8137, who is a non-independent consulting geologist under NI 43-101 standards. Readers should be aware that historical data may carry limitations and that LiDAR outputs will require geological interpretation before they can be used for definitive exploration decisions.
About UAS Inc. and closing perspective
Unmanned Aerial Services Inc. is a Canadian firm headquartered in Sudbury, Ontario, that specializes in advanced geospatial acquisition and remote inspections within challenging underground environments. Its service suite includes drone-enabled mapping, LiDAR and robotic scanning for raise bores, stopes, subsidence monitoring and infrastructure inspection, plus data processing, training and technical support. Giant Mining views this work as a safety-enhancing and data-rich precursor to its 2026 drill campaign and a means to modernize interpretations of historical workings while advancing systematic exploration.
