Drilling at the Boin Gold Deposit

KBRC347B and KBRC357 to KBRC366 (11 RC holes totalling 2,042 m) were completed at Boin, targeting the north-central and central portions of the deposit. Drilling targeted near-surface oxidized, transition as well as shallow sulphide mineralization with a goal of infill drilling for resource conversion to improve the confidence level as well as grow the existing Mineral Resource Estimate. RC drilling at Boin consisted of 50-metre spaced sections with drill holes spaced every 25 metres along the sections. The holes reported in this news release are distributed across 3 separate sections spanning 200 metres of strike length in the north-central area of Boin and 5 separate sections spanning 1.3 kilometres of strike length in the central area of Boin.

5 RC holes totalling 929 m (KBRC357 to KBRC361) were drilled on the north-central portion of the structure at Boin. KBRC357 intersected 4.41 g/t Au over 24.0 m from 126 m within the upper sulphide mineralization, including a higher-grade interval in the central portion of the structure of 9.08 g/t Au over 10.0 m from 132 m. KBRC357 also intersected a second interval of 1.07 g/t Au over 8.0 m from 113 m within the transition and upper sulphide horizon. Hole KBRC360, drilled 200 metres north of KBRC357, intersected 1.58 g/t Au over 52.0 m from 75 m, including a higher-grade interval of 3.04 g/t Au over 16.0 m from 96 m within the transitional mineralization. Within this hole, a second structure was encountered within the sulphide mineralization of 0.62 g/t Au over 22.0 m from 155 m, with KBRC360 ending in mineralization and the majority of this second interval encountered below the limits of the pit that constrains the current Mineral Resource Estimate at Boin. Additional drilling in the north-central area of Boin encountered wide zones of gold mineralization with above average grade gold mineralization, including KBRC359, drilled 25 metres to the east of KBRC360 on the same section, with 0.87 g/t gold over 34.0 m from 110 m intersected within the transitional and upper sulphide horizon. KBRC361, drilled 150 metres to the east of KBRC359 and directed back toward the west, intersected multiple zones within the sulphide mineralization including 2.13 g/t Au over 13.0 m from 157 m.

6 RC holes totalling 1,113 m (KBRC347B, KBRC362 to KBRC366) were drilled on the central portion of the structure at Boin, approximately one kilometre to the south of the north-central area. KBRC347B intersected 1.05 g/t Au over 38.0 m from 134 m within the sulphide horizon, with a second interval of 0.58 g/t over 17.0 m from 42 m in the near surface oxide mineralization. KBRC366, drilled 50 m to the east on the same section as KBRC347B, intersected a higher-grade zone in the sulphides with 2.01 g/t Au over 11.0 m from 192 m. KBRC362, drilled 300 m to the south of KBRC347B, intersected 0.66 g/t Au over 52.0 m from 158 m in the sulphide horizon, with the hole ending in mineralization and the entirety of this interval occurring below the limits of the pit that constrains the current Mineral Resource Estimate at Boin.

This drilling continues to confirm continuity along strike and down dip for the principal structures which comprise the Boin Gold Deposit. The width and gold grades within these drill results are consistent with prior wider-spaced drilling completed at Boin. The Company anticipates that these results, along with drill results previously released from the 2024 - 2025 drill program, should improve the confidence level of the existing Mineral Resource Estimate. This recent drilling was drilled in areas where the previous pit constrained Mineral Resource Estimate was classified as Inferred. The results of this recent drilling should allow for conversion of a substantial portion of mineralization within these areas to the Indicated category.

2024 - 2025 Enchi Work Program

A 35,000-metre drill program is underway at Enchi, targeting near-surface oxide and shallow sulphide mineralization with a primary goal of infill drilling for resource conversion to improve the confidence level of the existing Mineral Resource Estimate. Most of the infill drilling is allocated to the two largest deposits at Enchi, Boin and Sewum. Improving the confidence level of the Mineral Resource Estimate at Enchi is a key component of the development work required to be completed in advance of commissioning a Pre-Feasibility Study for the Project. A subset of the drill program will also focus on outlining resource growth, with all deposit areas and pre-resource targets at Enchi remaining open along strike and at depth, providing for future resource growth across the district-scale property.

Additional exploration and development work is on-going at Enchi, including metallurgical testwork, trenching, hydrogeological testing, geotechnical work, environmental work and soil sampling. Drone topographic surveys have been completed, expanding on previously completed work, at the Kwakyekrom and Tokosea deposit areas to provide detailed topographic information required to improve the confidence level of each deposit’s Mineral Resource Estimate. Additionally, the drone survey was completed across the proposed heap leach facility area to contribute additional data for future detailed engineering studies. An airborne magnetic survey tested grass roots targets related to a series of gold-in-soil anomalies and gold mineralization identified in trenching. Soil sampling is also currently being completed on the Omanpe and Abotia licenses with a goal of further defining early-stage targets across Enchi for future trenching and drilling.

Boin Gold Zone

Boin is one of the five deposits which comprise the Mineral Resource Estimate at Enchi (Boin has an Indicated Mineral Resource of 13.0 million tonnes grading 0.62 g/t Au containing 258,200 ounces and Inferred Mineral Resource of 15.9 million tonnes grading 0.68 g/t Au containing 349,600 ounces). Boin is located 10 kilometres south of the town of Enchi, with nearby roads and power and further access provided by a series of drill roads. Boin is outlined on surface by a greater than six-kilometre-long by up to one-kilometre-wide gold in soil anomaly. An airborne geophysical anomaly coincident with the Boin structure extends for a further kilometre north and three kilometres south beyond the limits of current drilling. To date, approximately 40% of the gold-in-soil anomaly at Boin is untested by drilling, with the average vertical depth of all holes drilled to date at Boin only down to 100 metres.

Enchi Gold Project Mineral Resource Estimate

The Enchi Gold Project hosts an Indicated Mineral Resource of 41.7 million tonnes grading 0.55 g/t Au containing 743,500 ounces gold and an Inferred Mineral Resource of 46.6 million tonnes grading 0.65 g/t Au containing 972,000 ounces. Mineral resource estimation practices are in accordance with CIM Estimation of Mineral Resource and Mineral Reserve Best Practice Guidelines (November 29, 2019) and follow CIM Definition Standards for Mineral Resources and Mineral Reserves (May 10, 2014), that are incorporated by reference into National Instrument 43-101 ("NI 43-101"). The Mineral Resource Estimate is from the technical report titled "NI 43-101 Technical Report, Preliminary Economic Assessment on the Enchi Gold Project" dated June 7, 2024, with an effective date of April 24, 2024, prepared for Newcore by Preetham Nayak, P.Eng., Ryda Peung, P.Eng., and Zunedbhai Shaikh, P.Eng., of Lycopodium Minerals Canada Ltd.; Kerrine Azougarh, P.Eng., of Micon International Limited; and Simon Meadows Smith, P.Eng. / P.Geo., of SEMS Exploration in accordance with NI 43-101, and is available under the Company’s profile on SEDAR+ at www.sedarplus.ca.
