Newcore Gold Ltd. (TSX-V: NCAU) (OTCQX: NCAUF) is pleased to announce additional drill results from the 80,000-metre drill program underway at the Company’s Enchi Gold Project in Ghana. Diamond Drilling at the Nyam Gold Deposit encountered high-grade gold mineralization in the upper fresh mineralization, below the limits of the pits that constrain the Mineral Reserves. Hole NBDD086 intersected 3.51 grams per tonne gold over 21.0 metres from 245 m, including 5.91 g/t Au over 9.0 m from 251 m. Drilling continues to demonstrate the continuity of gold mineralization and potential for resource growth at Enchi. Results from drilling completed in 2026, including drilling targeting higher-grade mineralization at depth, are expected to be incorporated into future project economic studies and may support further mine plan optimization.

Highlights from Diamond Drilling at the Nyam Gold Deposit at Enchi

• Drilling intersected high-grade gold mineralization above the mineral reserve grade and below the limits of the pits that constrain the Mineral Reserves.
  • Diamond drill hole NBDD086 intersected 3.51 g/t Au over 21.0 m from 245 m, with a higher-grade interval of 5.91 g/t Au over 9.0 m from 251 m.
  • Hole NBDD085 intersected 1.61 g/t Au over 14.0 m from 278 m, with a higher-grade interval of 2.94 g/t Au over 7.0 m from 284 m.

• Diamond drilling tested the down dip and lateral extensions to high-grade gold mineralization previously identified at Nyam.
  • Hole NBDD080 intersected 1.40 g/t Au over 21.0 m from 317 m, including 2.08 g/t Au over 11.0 m from 319 m.
  • Hole NBDD081 intersected 0.98 g/t Au over 28.0 m from 254 m, including 1.61 g/t Au over 8.0 m from 258 m and 2.19 g/t Au over 5.0 m from 277 m.
• Drill results not included in Mineral Resource Estimate and Pre-Feasibility Study, with drilling continuing to highlight Enchi’s longer-term prospectivity.
  • Drilling reported in this news release targeted mineralization to depth and reached a maximum vertical depth of 300 metres. The average vertical depth of all holes drilled to date at Nyam is only down to 100 metres.
  • All deposits at Enchi remain open for expansion along strike and to depth.

Greg Smith, VP Exploration of Newcore stated, “Results from drilling at Nyam continue to demonstrate the potential for high-grade gold and continuity of gold mineralization to depth. These holes successfully intersected gold mineralization below the reserve pits and in areas that have historically seen limited drilling. As the third largest deposit currently defined at Enchi, Nyam remains open along strike and at depth, with this drilling continuing to support our interpretation that the mineralized system continues at depth. With four drill rigs active at site, we look forward to continuing to define the opportunity to add higher-grade gold into the early years of the mine plan in future economic studies, while concurrently expanding the mineralized footprint and proving out the higher-grade potential at Enchi.”

This release reports results for 11 DD holes totalling 4,123 m (NBDD070 to NBDD072B, NBDD079A to NBDD086) targeting the Nyam Gold Deposit, with all holes intersecting gold mineralization. A total of 44,651 m in 283 holes has been reported to date as part of the ongoing drill program at Enchi, with 99% of holes intersecting gold mineralization.

Diamond Drilling at the Nyam Gold Deposit

NBDD070 to NBDD072B and NBDD079A to NBDD086 (11 DD holes totalling 4,123 m) were completed at Nyam, targeting high-grade mineralization within the fresh mineral horizon. The goal of this drilling was to continue to expand high-grade mineralization at depth. The 11 holes tested multiple high-grade shoots at depth which were previously identified through drilling. This drilling included some of the deepest holes completed to date at Nyam, reaching a maximum vertical depth of 300 metres, intersecting mineralization below prior intercepts and defining the continuity of gold mineralization to depth. The holes reported in this news release were distributed across 9 separate sections spread along a 1.2 km strike length.

Four diamond drill holes totalling 1,573 m (NBDD080, NBDD081, NBDD085, NBDD086) targeted extensions to a southern high-grade shoot identified at Nyam. Hole NBDD086 intersected 3.51 g/t Au over 21.0 m from 245 m, with a higher-grade interval of 5.91 g/t Au over 9.0 m from 251 m. Hole NBDD085, drilled on the same section, intersected 1.61 g/t Au over 14.0 m from 278 m, with a higher-grade interval of 2.94 g/t Au over 7.0 m from 284 m. Hole NBDD080 intersected several gold zones including a broad high-grade gold mineralized structure with 1.40 g/t Au over 21.0 m from 317 m, including 2.08 g/t Au over 11.0 m from 319 m, and a second zone with 2.18 g/t Au over 6.0 m from 354 m. Hole NBDD081, collared 200 metres south of NBDD080, intersected 0.98 g/t Au over 28.0 m from 254 m, including 1.61 g/t Au over 8.0 m from 258 m and 2.19 g/t Au over 5.0 m from 277 m.

Five diamond drill holes totalling 2,031 m (NBDD070 to NBDD072B, NBDD079A, NBDD082) targeted a central high-grade shoot identified at Nyam, with drilling intersecting mineralization above the current resource grade. Hole NBDD071 intersected multiple gold mineralized structures including 0.50 g/t Au over 37.5 m from 224 m, including a higher-grade interval of 1.18 g/t Au over 3.0 m from 226 m; a second interval of 0.79 g/t Au over 11.0 m from 283 m, with a higher-grade interval of 1.51 g/t Au over 2.0 m from 283 m; and a third interval of 0.96 g/t Au over 11.0 m from 327 m, with a higher-grade interval of 1.67 g/t Au over 5.0 m from 327 m. Hole NBDD070, collared 100 metres north of NBDD071, intersected 0.46 g/t Au over 23.0 m from 284.5 m, including a higher-grade interval of 1.77 g/t Au over 1.0 m from 292 m and 1.37 g/t Au over 2.0 m from 299 m. Hole NBDD079A, collared 80 metres north of NBDD071, intersected 0.68 g/t Au over 10.8 m from 299.6 m, with a higher-grade interval of 1.47 g/t Au over 2.0 m from 304.9 m. Hole NBDD072B, collared 140 metres north of NBDD071, intersected multiple gold mineralized zones including 0.82 g/t Au over 5.0 m from 172 m, including a higher-grade interval of 3.14 g/t Au over 1.0 m from 176 m; a second zone of 0.55 g/t Au over 5.0 m from 239 m; and a third zone of 1.23 g/t Au over 2.0 m from 280 m.

Two diamond drill holes totalling 520 m (NBDD083, NBDD084) targeted a prospective area at Nyam where an additional high-grade shoot has potentially been identified to the north. Hole NBDD084 is one of the first deeper holes completed in that area and returned a higher-grade interval of 1.20 g/t Au over 3.0 m from 120 m.

Diamond drilling completed at Nyam continues to intersect mineralization above the resource grade and continues to confirm continuity along strike and down dip, extending the principal structures which comprise the Nyam Gold Deposit.

Enchi Work Program

An 80,000 metre drill program is underway at Enchi. The drill program is focused on resource conversion, resource growth and discovery. Reverse Circulation drilling is targeting near-surface mineralization (oxide, transition, and shallow fresh mineralization) focused on resource conversion and continuing to define the potential for reserve and resource growth along strike at existing deposits. Diamond drilling is targeting the high-grade potential at depth. The completed first phase of the drill program was infill drilling for resource conversion, with only the first 28,000 metres of the drill program incorporated into an updated Mineral Resource Estimate announced on March 18, 2026 that formed the basis for a Pre-Feasibility Study. All deposit areas and pre-resource targets at Enchi remain open along strike and at depth, providing for future resource growth across the district-scale property.

Development work continues at Enchi, in support of project advancement, including metallurgical testwork, hydrogeological testing, geotechnical work, and environmental work. A Pre-Feasibility Study was completed in June 2026 (see news release dated June 24, 2026), outlining a base case assessment of developing an open pit, standard milling and carbon-in-leach operation using contract mining and processing 5.5 Mtpa. Recent drilling completed at Enchi has highlighted potential for resource growth, with high-grade encountered at depth and mineralization delineated below the pits that constrain the current Mineral Reserve and Mineral Resource Estimates. Drill results reported in 2026 have not been included in the Mineral Resource Estimate and PFS.

Nyam Gold Deposit

Nyam is one of the five deposits which comprise the Mineral Resource Estimate at Enchi (Nyam has an Indicated Mineral Resource of 13.5 million tonnes grading 0.66 g/t Au containing 287,000 ounces and an Inferred Mineral Resource of 5.5 million tonnes grading 0.68 g/t Au containing 120,000 ounces). Nyam is located 15 kilometres east of the town of Enchi, with nearby roads and power and further access provided by a series of drill roads. An airborne geophysical anomaly coincident with the Nyam Gold Deposit defines a complex series of linear high conductivity trends, reflective of the multiple sub-parallel gold-bearing structures. To date, approximately 30% of the gold-in-soil anomaly at Nyam is untested by drilling, with the average vertical depth of all holes drilled to date at Nyam only down to 100 metres.
