Giant Mining Corp. Submits Core For Assay From 1,963 Foot Hole Mhb-34 At Majuba Hill Copper Project- Advancing Critical Minerals

Giant Mining Corp. (CSE: BFG | OTC: BFGFF | FWB: YW5) (CSE:BFG.WT.A) (“Giant Mining” or the “Company”) is pleased to announce that all core from hole MHB-34, which was drilled to a total depth of 1,963 feet (598.3 metres), has been sampled and submitted to ALS Global Services (ALS Labs) for analysis from the 5,484.5 Ft (1,671.68 meters) Spring 2025 Drill Program (“Core Program”) at the Majuba Hill Porphyry Copper-Silver-Gold Project (“Majuba Hill”), located in Pershing County, Nevada.

MHB-34 was the third hole of the five hole program. Results from MHB-32, the first hole, were recently announced highlighting the expansion of mineralization at Majuba Hill most notably: 169.5 ft of 0.41% Cu Including 40 ft of 1.36% Cu and 10 ft at 4.36% Cu. See Press release here.

About Hole MHB-34

- Visible native copper observed beyond 1,850 feet signals scale and strength at Majuba Hill.

- Strong presence of native copper, cuprite, and chalcopyrite suggests proximity to a primary copper sulfide zone.

- Majuba Hill positioned as a homegrown U.S. critical minerals project with Tier 1 infrastructure advantages.

As shown in the accompanying images (Figure 2-5), native copper, cuprite, and chalcopyrite was persistent in the deeper part of MHB-34.

Majuba Hill’s critically important characteristics are as follows:

Location:
Nevada, USA — a globally top-ranked mining jurisdiction, ranked #1 in the Fraser Institute’s 2022 Annual Survey of Mining Companies.

Project Size:
9,684 Acres

Infrastructure:
The Majuba Hill property is 113 road km (70 miles) southwest of Winnemucca, Nevada, and 251 km (156 miles) northeast of Reno. Access is by well-maintained county roads from the Imlay, Nevada exit on U.S. Interstate 80, and traveling westward 23 miles. People, Roads, Power, and Water are the basic elements when considering infrastructure and Majuba Hill already has a solid infrastructure foundation for building a large facility which will provide significant savings compared to more remote projects.

History:
Historical Producer

Drilling:
Approximately 89395 feet of drilling to date. Rough replacement value of drilling USD $12.1 Million using current costs.

Mineralization:
The project shows indications of a potentially large Cu – Ag ± Au mineralized body with many features in common with both large porphyry copper, silver, and gold projects.

Expandability:
The IP survey, deep drilling, and step-out drilling indicate significant expansion potential, with mineralization open in all directions.

Fully Financed: Secured funding for 2025 Drilling Campaign


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. Drill core samples are sawn in half lengthwise and one half is placed in labeled cloth sample bags. Sample bags 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.

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.
