Drilling at Middle Chief & Big Chief Prospects

Assay results returned from 20 holes, 3,581m (LCG-001-005, LCG-007-008, LCG009, LCG-009D1, LCG-009D2, LCG-010 and LCG-010D1) at the Chiefs Trend confirm the extensive high-grade mineralization highlighted by Gladiator's data compilation of historical drilling (refer to news release 16^th Nov 2023). Mineralization remains open in all directions with some holes finishing in high-grade copper and gold mineralization due to difficult ground conditions. Copper - gold mineralization highlighted from these assay returns includes:

• LCG-009: 11m @ 1.67% Cu and 0.63 g/t Au from 194m.

• LCG-009D1: 20.44m @ 2.17% Cu and 0.34 g/t Au from 221.6m to EOH.LCG-009D2: 8.7m @ 2.06% Cu and 0.13 g/t Au from 167m.

• LCG-009D2: 8.7m @ 2.06% Cu and 0.13 g/t Au from 167m.

In addition, significant exploration upside remains with extensive widths of anomalous copper intersected in initial 200m spaced step out drilling north of the known Middle Chief Mineralization. Drillhole LCG-010D1 intersected significant anomalous copper (Plus 40m > 0.1 Cu%, including 1m @ 1.28% Cu and 1.61 g/t Au) that is interpreted as being immediately distal to the mineralised trend. Gladiator plans to complete Down-Hole Electromagnetic (DHEM) prior to recommencing drilling targeting extensions to the known Middle Chief Mineralisation. These results confirm mineralization to be associated with magnetite alteration as indicated in the recently completed drone-borne magnetic survey where magnetic anomalism is reported over 500 meters at Middle Chief extending into Big Chief.

These results are in addition to analytical results reported on March 5, 2024, including:

• LCG-003: Recovered core @ 2.71% Cu and 1.39 g/t Au within a 13.75m mineralized zone from 256m to end of hole (approximately 270 m) that failed in 0.25m @ 2.76% Cu and 0.28 g/t Au.

• LCG-001D1: 22m @ 1.41% Cu and 0.28 g/t Au from 208m.

• LCG-001: 6m @ 1.56 % Cu and 1.06 g/t Au from 213m and 16m @ 1.29% Cu and 0.61 g/t Au from 249m.

• LCG-001D2: 10m @ 0.83% Cu and 0.19 g/t Au from 62m, 4m @ 1.03 Cu and 0.19 g/t Au from 84m and 10m @ 1.35% Cu and 0.51g/t Au from 196m.

Please refer to Table 1 below for a full listing of drill results:

 

Table 1: Chief's Trend Significant Intersections (Recent Drilling)

Copper Equivalent (CuEq) was based on the following assumed metal prices on the 21 April 2024 of $US 9.876 per tonne Cu, $2,390 per Ounce Au & US$28.69 per Ounce Ag. Mo was excluded from the calculation and recovery is assumed to be 100% as no metallurgical test work has been completed.

Drilling has now defined unmined, near surface magnetite-copper skarn mineralization over more than 600m's of strike north of the historical mining operations at Little Chief.

Historical drilling at the Chiefs Trend prospects was selectively sampled for copper only. Given the recent significant gold intervals returned from these initial assay results Gladiator intends to assay all future drilling and sampling for additional credits including gold, silver and molybdenum which were proven significant contributors to the economics of historic operations at Little Chief.

QA / QC and Data Verification

Drilling completed by Gladiator was irregularly spaced to test parts of the mineralized systems, holes were directionally surveyed utilising a North Seeking Gyro direction tool. Drill collars were or are to be subsequently surveyed utilising a high-accuracy RTK DGPS system.

Upon drilling of diamond core Gladiator undertakes geological logging, marking up of lineal length of the core, recording core recovery, Geotech measurements such as RQD's and undertakes core photographs.

Based on the geological logging, core is then marked up for sampling with a new sampling ticket that matches the submitted sample for analysis at the start of the sample interval, the drill core is then cut in half utilizing a core saw equipped with a diamond saw blade. The core samples are then sent for analysis and the remaining half core retained for future reference. Certified Reference Materials (CRMs) or known blank material is placed within the sampling sequence at a nominal sampling rate of 1 in 20 samples to monitor the Laboratory. Samples are submitted to the ALS Global Laboratory (Canada).

Samples subject to this release were crushed to 70% less than 2mm before pulverizing to better than 85% passing 75 microns. Samples were then analysed by ALS method ME-ICP61 (Aqua Regia with ICP-MS finish), with over limits for Cu analysed by method CU-OG62 (Aqua Regia with ICP-MS finish). As part of this process, Gladiator also captures the required sampling metadata to potentially utilize the core and analysis for any future requirements if deemed acceptable. The QA/QC meets the current required standards under reporting instruments, such as NI-43-101. At this point the Company regards the data collected from this exercise as reliable for the purposes of identifying mineralization and future exploration targets and may be used to inform future drilling and exploration campaigns.

For information regarding QA/ QC and Data verification for the Historically Reported Intercepts, please refer to the Company's release dated 18^th January, 2024 "Gladiator Commences Drilling at the Middle Chief Copper Prospect" or the Company's release dated 16^th November, 2023 "High-Grade Copper Mineralization Identified at Middle Chief & Class 1 Permit Extension Granted". Please note the Company believes that the historical drill results do not conform to the presently accepted industry standards.

The historical mineral resources discussed in this press release were calculated using mining industry standard practices for estimating Mineral Resource and Mineral Reserves prior to the implementation of the current CIM standards for mineral resource estimation (as defined by the CIM Definition Standard on Mineral Resources and Mineral Reserves dated May 10, 2014). The reader is cautioned not to treat them, or any part of them, as current mineral resources or reserves. An independent Qualified Person ('QP'), has not done sufficient work to classify the estimate discussed as current mineral resources or reserves and therefore the estimate should be treated as historical in nature and not current mineral resources or mineral reserves. The historical resources have been included simply to demonstrate the mineral potential of the Whitehorse Copper Project. A thorough review of all historical data performed by a QP, along with additional exploration work to confirm results, would be required in order to produce a current mineral resource estimate for each of the key prospects. For greater certainty, the Company confirms that it does not have a current mineral resource on any part of its Whitehorse Copper Project.

Where Copper Equivalents have been stated, Assumptions of the pricing are referenced in the tabulated results and recovery is assumed to be 100% as no metallurgical data is available. The following equation was used to calculate copper equivalence:

Copper Equivalent (CuEq) = ((Cu% * CuPrice 1% Per Tonne) + ((Au (g/t) x (AuPrice/31.105)) + ((Ag (g/t) x (AgPrice/31.105))) / CuPrice 1% Per Tonne

Molybdenum is excluded from the Little Chief Calculation as historically it has not been referenced.
