The Vancouver-based company announced on March 20, 2026 that its 2026 exploration blueprint has been adjusted to incorporate two deep diamond drill holes within an up to 10,000-foot core drilling program. The holes are being sited using a blend of legacy datasets, fresh surface mapping and soil sampling, and outputs from ExploreTech A.I. — a collaboration intended to refine geological interpretation and prioritize targets at the Majuba Hill Copper-Silver-Gold Project in Pershing County, Nevada.
Giant Mining frames these additional deep holes as strategic tests for down-plunge continuity and potential source zones beneath old workings. The company emphasizes that the targets remain conceptual and that more drilling is required to define any mineral resource. The program builds on prior work done across 2026–2026 that identified multiple mineralized breccia bodies associated with hydrothermal-magmatic tourmaline breccias and breccia pipe margins.

Program overview and drilling phases
The 2026 plan is structured into two phases: an initial program of up to 5,000 feet of diamond drilling combined with underground mapping, sampling, and surface geochemical surveys, followed by a second phase that would add up to 5,000 feet more. The two newly announced deep holes are part of this Drill Program, intended to probe priority zones at depth. Management states the work is fully funded for the next phase and will be executed with modern drilling crews and logistical support in the field.
Targets and technical approach
One of the deep holes will target a recently mapped breccia body that emerged from late 2026 surface programs (see the company news release dated November 19, 2026). This target is considered prospective for the style of mineralization typically associated with hydrothermal breccia systems. The second hole is designed to test extensions beneath historical underground workings where limited contemporary drilling exists, aiming to locate potential feeder zones and continuations of known mineralized structures.
Integration of datasets and A.I.
Giant Mining says target selection relies on an integrated approach that includes historical drill logs (including work by previous operators such as Freeport Sulfur in the 1940’s and Mine Finders in the 1970’s), updated geological modelling, soil geochemistry, and emergent targets produced by ExploreTech A.I.. The company believes that coupling automated analytics with hands-on geological interpretation will sharpen the understanding of scale and continuity of mineralization at depth.
Project context, quality control and oversight
Majuba Hill is a large intrusive-related Cu-Ag-Au system with historical drilling totaling approximately 89,395 feet and a documented history of copper production. The property covers 9,684 acres and benefits from existing access and infrastructure — approximately 113 road kilometers (70 miles) southwest of Winnemucca and 251 kilometers (156 miles) northeast of Reno — which the company cites as a meaningful cost advantage compared with remote projects.
Data integrity and qualified oversight
Historical analytical work referenced by Giant Mining was completed by ALS USA Inc. in Elko, an ISO/IEC 17025 accredited prep laboratory, and industry-standard QA/QC protocols were used, including certified reference materials, blanks, and duplicates. The technical content has been reviewed by E.L. “Buster” Hunsaker III, CPG 8137, who is identified as the company’s Qualified Person under NI 43-101 standards.
Corporate and community engagement
Giant Mining also disclosed a marketing extension with Gold Standard Media (GSM) dated March 19, 2026, providing investor awareness services through to September 7, 2026 for fees up to US$450,000. In parallel, the company noted participation in the Ralph J. Roberts Center for Research in Economic Geology (CREG) meetings at the University of Nevada, Reno, citing academic collaboration — including research by Alex Holmwood and a 2026 Master of Science thesis that contributed to the project’s geologic framework.
Giant Mining cautions that forward-looking statements underpinning the program are subject to exploration, permitting, market and other risks, and that the targets remain conceptual until adequate exploration establishes a mineral resource. The company continues to advance systematic drilling and technical evaluation while positioning Majuba Hill to respond to long-term demand for critical metals driven by global energy transitions.
