GREAT REPUBLIC MINING CORP. COMPLETES GEOPHYSICS PROGRAM AT PORCHER ISLAND VANADIUM-TITANIUM-IRON PROPERTY SAMPLES UP TO 0.17% VANADIUM (0.303% V2O5)

Great Republic Mining Corp. has released the results of the 2023 prospecting, sampling and ground geophysics program on company's Porcher Island vanadium-titanium-iron property in British Columbia, Canada. The field program expanded Vanadium mineralization discoveries on the Porcher Island property located on tidewater, 40 kilometres from the deepwater, all-season port of Prince Rupert.

Chief executive officer of Great Republic Mining, Fred Davidson, comments: "The company recognizes the importance of vanadium for industrial uses as well as the emerging vanadium battery technologies. Our project is advantageously located on the Pacific Coast. Our field program has demonstrated both the presence of significant vanadium values in the context of encouraging, large-scale magnetic anomalies over an area of several square kilometres."

2023 program

The multidisciplinary program consisted of sampling a plus a reconnaissance ground magnetic survey over the central portion of the complex to augment earlier airborne magnetics, where the target geology is anomalously magnetic.

• 30 rock samples were taken with values ranging with the highest being 0.17 per cent V which is equivalent to 0.303 per cent V205;
• 2019 airborne magnetic geophysics was utilized, and ground truthing confirmed a number of distinct high magnetic anomalies;
• Five line kilometres of ground magnetics were conducted in a core area, highlighting numerous localized magnetic highs for future exploration;
• The 2023 field program confirmed the potential for mineralization of a large-scale stratified vanadium-iron-titanium mineralized system on the company's Porcher Island property;
• Historic airborne magnetics survey highlighted two other areas, 2.5 by 4.5 kilometres and two by three km which were sampled, returning anomalous vanadium which will be followed up.

Geology and mineralization

Great Republic's Porcher Island property contains strongly magnetic units of interbedded, coarse to fine gabbros and pyroxenite that intrude into fine-grained volcanics. Mafic units are composed of interbanded hornblende gabbro, anorthositic gabbro and pyroxenite. Vanadium mineralization is found within seams of titaniferous magnetite and ilmenite in the gabbro and pyroxenite units. Clustered mineralized seams identified to date, individually of up to half a metre thick, run north to south and at a moderate dip primarily along ridges on the property.

Vanadium mineralized units strongly correlate within strongly magnetic signatures trending north to south throughout the Porcher Island property. A previous 2019 exploration program highlighted numerous seams associated with magnetic highs with values ranging from 0.04 per cent V2O5 to 0.42 per cent V2O5. The 2023 field exploration program continued to focus on mapping and sampling of mineralized areas highlighted in the 2019 field program. Values ranging from below detection to 0.17 per cent V validating previous work and highlighting new potential seams. Five line km at 100-metre spacing of ground magnetics were conducted over a core area of known vanadium mineralization and airborne magnetic highs to validate the technique for future exploration campaigns. This 2023 ground magnetics survey highlighted numerous localized magnetic highs for future mapping and sampling as well as provided a higher resolution survey to help build a structural model of the Porcher Island property. The 2019 airborne magnetic survey produced two large 2.5 by 4.5 km and two by three km anomalies leaving ample room for further ground magnetics and prospecting in future, more comprehensive campaigns.

Outcropping grab rock sampling returned a sample with 0.17 per cent vanadium, which is equivalent to 0.303 per cent vanadium pentoxide. Assay values encountered at Porcher Island compare favourably to mineral resources of global peer projects like Tivan Ltd. Speedwah in Australia which hosts that shown in the attached table.

The qualified person has not verified the information on the Speedwah project and the information disclosed is not necessarily indicative of mineralization on the Porcher Island property.

Sampling and laboratory methodology

Samples were taken using rock hammers and placed in poly sample bags with a location point taken using a GPS. The samples were then taken to the ALS prep sample lab in Terrace, B.C. Samples were prepared using PREP-31. Samples were then shipped to ALS Vancouver (an accredited laboratory) and analytical methods ME_XRF21n and ME-ICP61 were utilized run. ME_XRF21n is a lithium borate fusion and XRF finish to for the vanadium, iron and titanium potential. ME-ICP61 is a four-acid digest to provide a strong geochemical data set for results.

Vanadium

The commercial equivalent vanadium oxide (V2O5) trades at market price of $5.80 (U.S.) per pound ($12,970 (U.S.)/tonne) and converts to a factor of 1.7852 to one unit of vanadium. Vanadium demand is growing in new battery technology applications such as stationary redox energy storage facilities supplementing the demand in traditional steel alloys.
