VANCOUVER, BC — June 20, 2025 — TheNewswire - Giant Mining Corp. (CSE: BFG | OTC: BFGFF | FWB: YW5 | CSE: BFG.WT.A | CSE: BFG.WT.B) (“Giant Mining” or the “Company”) is pleased to announce the expansion of its baseline exploration program at the Majuba Hill Porphyry Copper-Silver-Gold Project (“Majuba Hill”), located in Pershing County, Nevada. This decision follows encouraging high-grade copper results from the Company’s 2024–2025 core drilling campaign.
Recent drilling has confirmed significant high-grade copper mineralization, with core holes MHB-30 and MHB-32 yielding particularly promising intercepts. These results, combined with detailed geological studies of porphyry-related magmatic hydrothermal breccias and ExploreTech’s AI-driven geophysical modeling, have led the Company to accelerate and expand its exploration initiatives at Majuba Hill.
David Greenway, CEO of Giant Mining, commented: “The 2025 drill program at Majuba Hill has been our most ambitious and technically advanced to date. The consistency and predictability of results from our focused drilling campaigns have strengthened the technical team's confidence in advancing Majuba as the next significant copper discovery in Nevada, with the potential to support a future mineral resource estimate.
While assays are still pending from Phase 1 2025, visual core logging and detailed analysis of the 2024 core have already provided a solid foundation for planning Phase 2 in Q3 or Q4 2025.”
Both holes intersected high-grade copper within porphyry-related, tourmaline-matrix breccia zones (see Table 1), reinforcing the potential for a robust mineralized system at depth and laterally across the project area.
Giant Mining has compiled extensive surface geology and geophysical datasets at Majuba Hill, which have now been fully integrated into an AI-driven modeling system developed by ExploreTech. Building on the success of this approach, the Company is initiating Phase 2 evaluation, combining advanced machine-learning insights with a targeted, boots-on-the-ground breccia mapping and sampling program in the Northern Zone Breccia Corridor (see Figure 2).
The Northern Zone hosts porphyry-related, magmatic-hydrothermal breccias that exhibit many of the same geological features encountered in the Company’s 2024 and 2025 drill campaigns. Historical surface geochemical data from this area reveals extensive anomalies in copper, silver, molybdenum, and tin, further supporting its potential as a high-priority exploration target (see Figure 3).

High-Grade Copper Intersected in 2024–2025 Drilling
During 2024 and 2025, seven core drill holes (MHB-30 through MHB-36) were completed, totaling 7,370.5 feet (2,246.53 meters) of drilling. With this addition, cumulative drilling at the Majuba Hill Project now stands at 89,395 feet (27,247.5 meters), significantly refining the geological model and enhancing the Company’s understanding of the mineralization system.
The primary objective of the 2024–2025 core drilling program was to conduct step-out drilling from known copper-bearing zones, expanding the mineralized footprint and advancing the project toward the completion of a maiden mineral resource estimate.
Key highlights include:
Hole MHB-30

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),containing10 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 hole.

Hole MHB 36 – An AI-Driven Step Out Discovery or Potential Deposit Extension
Due to the intersection of the sulfides predicted by modeling the hole was drilled to 1100 feet (335.28 meters). MHB-36 intersected disseminated and vein-hosted chalcopyrite mineralization within porphyry-related 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 ExploreTech’s AI prediction.

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.
