Giant Mining Continues Engagement of RESPEC Engineering to Incorporate 2024 and Spring 2025 Core Drilling Into Modeling at Majuba Hill Copper-Silver-Gold Project, Nevada
VANCOUVER, BRITISH COLUMBIA - June 9, 2025 (NEWMEDIAWIRE) - Giant Mining Corp. (CSE: BFG | OTC: BFGFF | FWB: YW5 | CSE: | CSE: ("Giant Mining" or the "Company") is pleased to announce that it is continuing its engagement with RESPEC Company LLC ("RESPEC") of Reno, Nevada. RESPEC will incorporate drilling data from the 2024 diamond core and from the 2025 spring diamond core drilling program (the "Core Program") at the Majuba Hill Porphyry Copper-Silver-Gold Project ("Majuba Hill") in Pershing County, Nevada, into the database used for the Technical Report for the Majuba Hill Copper Project, Pershing County, Nevada, USA. (the "Report").
The Report had an effective date of March 14, 2023, a Report Date of June 20, 2023, was amended on February 4, 2025, and was authored by Jeffrey M. Bickel C.P.G. RESPEC Company LLC and W. Joseph Schlitt, PhD, QP.
New assays and geologic data from the effective date of the Report will be compiled and incorporated to accommodate all of the observed geology and provide the best understanding for the mineralization at Majuba Hill.
"The 2025 drill season at Majuba Hill was our most ambitious and technically advanced to date. Strong early visual mineralization exceeded our expectations and led to the addition of a fifth hole - MHB-36 - guided by AI-assisted geophysical modeling. This AI-targeted hole intersected promising mineralization and marks a significant step-out from previously identified zones, indicating the potential for a new discovery. Meanwhile, core hole MHB-34 reached a depth of 1,963 feet and encountered native copper, reinforcing the scale and depth potential of the Majuba Hill Copper-Silver-Gold system. We're excited to continue advancing the project with RESPEC as we move forward with Majuba Hill."
About RESPEC
RESPEC is an International group that applies engineering, applied sciences and technology to natural resources and has extensive experience in the Mineral and Exploration industry throughout Nevada and the western United States. RESPEC was founded in 1969 with over 600 employees and over USD $112 Million in Revenue (2022).
2025 Phase 1 Drill Program
In 2024 and 2025 a total of seven drill holes, MHB-30 through MHB-36, have been completed for a combined 7,370.5 feet (2,246.53 meters) of core drilling. This brings the cumulative total of drilling at Majuba Hill to 89,395 feet (27,247.5 meters), which will significantly enhance the Company's geological model and understanding of the mineralization.
Table 1: Majuba Hill 2024 and 2025 Drill Program Collar Details
The primary objective of the 2025 Core Program was to step out from and expand the known zones of copper mineralization and advance the Majuba Hill Project toward completing a mineral resource estimate. All drill core was transported to Giant Mining's secure core facility in Elko, Nevada, where it was logged, sawn, and sampled by Company personnel. The samples were submitted to ALS Global Services ("ALS Labs") for geochemical analysis, with sample preparation completed at their Elko facility and final assaying conducted at their laboratory in Vancouver, British Columbia.
Key highlights include:
MHB-30 (September 24, 2024 news release)
High-grade copper was sampled from core hole MHB-30 ("MHB-30") that was clearly associated with magmatic-hydrothermal, copper-bearing breccia zone. The breccia zone assays returned:
218.0 feet of 1.35% Cu and 73.4 g/t Ag from 0 to 218 feet (0-66.4 m) including
74.0 feet (22.6 meters) at 2.6% Cu and 30.1 g/t Ag Table 2: MHB-32 Significant Assay Intervals for assays reported to date. (*True widths are unknown.)
MHB-32
MHB-32 intersected two significant copper mineralized zones within a broader interval of 379.5 feet (115.7 m) grading 0.33% Cu and 16.97 ppm Ag, from 510 to 889.5 feet (155.5 to 271.1 m). These results extend the known mineralization deeper and further north than previous drilling. The two key intervals, detailed in Table 2, are:
85 feet (25.9 m) at 0.64% Cu and 50.89 ppm Ag from 510 to 595 feet (155.5 to 181.4 m)
169.5 feet (51.7 m) at 0.41% Cu and 9.51 ppm Ag from 720 to 889.5 feet (219.5 to 271.1 m), including:
40 feet (12.2 m) at 1.36% Cu and 13.33 ppm Ag from 780 to 820 feet (237.7 to 249.9 m), containing a higher-grade section of:
10 feet (3.0 m) at 4.36% Cu and 35.65 ppm Ag from 805 to 815 feet (245.4 to 248.4 m)
Core Hole MHB-32 was completed to a total depth of 889.5 feet (271.1 meters). The hole intersected copper-bearing, magmatic-hydrothermal breccias with secondary copper minerals, including azurite, malachite, and chalcocite. These transitioned into strongly oxidized copper sulfides, along with primary, unoxidized chalcopyrite near the bottom of the early success confirmed the vertical continuity of the mineralized system and the presence of breccia-hosted copper 34 Native Copper Encounter
Core Hole MHB-34 was drilled to a total depth of 1,963 feet (598.3 meters). The hole encountered persistent native copper, cuprite, and chalcopyrite mineralization in the deeper sections, with native copper observed beyond 1,850 visual results indicate a robust enrichment zone related to a porphyry system at depth and suggest proximity to a primary copper sulfide source.
MHB 36 An A.I. Driven Step Out Discovery or Potential Deposit Extension
The fifth and final drill hole of the Core Program, MHB-36, was planned for a total depth of 1,000 feet (304.8 meters). This hole was designed by Exploration Technologies ("ExploreTech") using its proprietary AI-assisted geophysical modeling system to test a high-potential resistivity anomaly delineated in the southern sector of the Majuba Hill project area. The AI-driven targeting approach aimed to identify geologically favorable zones with potential for new copper mineralization beyond the existing mineralization to the intersection of the sulfides predicted by modeling the hole was extended to 1100 feet (335.28 meters). MHB-36 intersected disseminated and vein-hosted chalcopyrite mineralization within intrusive and magmatic hydrothermal breccias, beginning at a downhole depth of 650 feet (198 meters). Mineralization was observed intermittently beyond 905 feet (274.32 meters), confirming the accuracy of the AI model and highlighting the potential for further extensions of copper-bearing zones in this underexplored Hill's critically important characteristics are as follows:

Quality Assurance/Quality Control ("QA/QC") Measures, Chain of Custody
The Company utilizes a QA/QC program using best industry practices at the Majuba Hill Project. The samples are placed in cloth sample bags and are transported from the Giant Mining secure warehouse to the ALS Labs Sample Prep Facility in Elko, Nevada. ALS Labs then securely transports the prepared pulps to their analytical lab in North Vancouver, B.C.
Drill core samples are sawn in half lengthwise and one half is placed in labeled cloth sample bags. All samples are analyzed for copper, gold, silver, and 33 other elements. Gold is determined by ALS Labs method Au-AA23 which is a fire assay with an AAS finish on a 30-gram split. Copper, silver, and the remaining 31 elements are determined by ALS Labs method ME-ICP61 which is a four-acid digestion and ICP-AES assay. Approximately 5% of the submitted samples are drill duplicates and copper-gold-porphyry commercial standard reference material pulps. The remaining pulps will be retrieved from ALS Labs.
