Diamond Drilling at the Boin Gold Deposit Intersects Gold Mineralization in the Fresh Mineralization, Below the Limits of the Pits that Constrain the Mineral Resource Estimate

Newcore Gold Ltd. (TSX-V: NCAU) (OTCQX: NCAUF) is pleased to announce additional drill results from the 60,000-metre drill program underway at the Company’s Enchi Gold Project in Ghana. Diamond Drilling at the Boin Gold Deposit encountered wide zones of gold mineralization in the fresh mineral horizon, below the limits of the pits that constrain the Mineral Resource Estimate. Hole KBDD107 intersected 1.23 grams per tonne gold over 33.0 metres from 337.0 m, including 2.16 g/t Au over 13.0 m from 357.0 m. Hole KBDD111 also intersected a wide zone of gold mineralization including 1.38 g/t Au over 15.0 m from 193.0 m, with a high-grade interval of 5.99 g/t Au over 3.0 m from 204.0 m. This news release reports results for diamond drilling com pleted at Boin. Drilling continues to demonstrate the continuity of gold mineralization and potential for resource growth at Enchi.

  • Hole KBDD109 intersected 1.56 g/t Au over 11.1 m from 252.9 m, including 2.84 g/t Au over 4.0 m from 25 9.0 m.

• Drill results not included in most recent Mineral Resource Estimate, with drilling continuing to prove out the potential for future resource growth at Enchi.
  • Boin is the second largest deposit currently identified at Enchi and remains open along strike and at depth.
  • This drilling reached a maximum vertical depth of 375 metres, the deepest intercepts drilled to date at Boin. The average vertical depth of all holes drilled to date at Boin is only down to 100 metres.

Greg Smith, VP Exploration of Newcore stated, “Drilling at our Enchi Gold Project in Ghana continues to highlight the potential for future resource growth, with recent diamond drilling at Boin successfully extending high-grade gold mineralizat ion below the current pit constrained Mineral Resource Estimate. These results support further drilling at depth as we advance our understanding of the Project’s scale, continuity and longer-term district scale potential.”

This release reports results for 10 DD holes totalling 3,654 m (KBDD106 to KBDD115A) targeting the Boin Gold Deposit, with all holes intersecting gold mineralization. A total of 38,458 m in 266 holes has been reported as part of the ongoing drill program at Enchi, with 98% of holes intersecting gold mineralization.

Diamond Drilling at the Boin Gold Deposit

KBDD106 to KBDD115A (10 DD holes totalling 3,654 m) were completed at Boin, targeting mineralization below the limits of the pits that constrain the Mineral Resource Estimate. This drilling also targeted mineral ization within the fresh mineral horizon at Boin with the goal of continuing to expand high-grade mineralization at depth. The 10 holes tested three high-grade shoots at depth which were previously identified through drilling, each approximately 400 to 500 metres in length. The drilling extended these high-grade shoots along strike and down dip, reaching a maximum vertical depth of 375 metres. This is the deepest drilling completed to date at Boin, intersecting mineralization below prior intercepts and defining the continuity of gold mineralization to depth. The holes reported in this news release were distributed across nine separate sections spread along a 1.7 kms strike length.

Five diamond drill holes totalling 1,689 m (KBDD106, KBDD107, KBDD109, KBDD110, KBDD114A) tested the central high-grade shoot at Boin. Hole KBDD107 targeted gold mineralization below the level of the pit which constrains the Mineral Resource Estimate. The hole extended gold minerali zation 100 metres down dip from the previous drilling completed on the section and intersected the main gold mineralized structure at an approximate vertical depth of 270 metres below surface. KBDD107 intersected multiple gold mineralized structures highlighted by 1.23 g/t Au over 33.0 m from 337.0 m, including 2.16 g/t Au over 13.0 m from 357.0 m. Hole KBDD109, collared 300 metres south of KBDD107, intersected 1.56 g/t Au over 11.1 m from 252.9 m, including 2.84 g/t Au over 4.0 m from 259.0 m.

Three diamond drill holes totaling 1,154 m (KBDD111 to KBDD113) tested the northern high-grade shoot at Boin. Hole KBDD111, drilled approximately one kilometre north of KBDD107, intersected 1.38 g/t Au over 15.0 m from 193.0 m, with a high-grade interval of 5.99 g/t Au over 3.0 m from 204.0 m. Hole KBDD113, drilled 150 metres north of KBDD111, intersected 0.64 g/t Au over 24.0 m from 353.0 m, including 1.39 g/t Au over 5.5 m from 354.0 m and a second structure of 0.45 g/t Au over 21.0 m from 381.0 m including 1.38 g/t Au over 2.0 m from 400.0 m.

Two diamond drill holes totaling 811 m (KBDD108 and KBDD115A) tested the southern high-grade shoot at Boin. Hole KBDD115A, drilled approximately one kilometre south of KBDD107, intersected 1.21 g/t Au over 9.0 m from 316.0 m, with a higher-grade sub-interval of 2.30 g/t Au over 3.3 m from 316.0 m.

Diamond drilling completed at Boin continues to confirm continuity down dip for the principal structures which comprise the central portion of the Boin Gold Deposit. The width and gold grades within these drill results are consistent with prior drilling completed in this area.

Enchi Work Program

The 60,000 metre drill program underway at Enchi commenced August 2024, targeting near-surface oxide and transition mineralization along with shallow fresh mineralization. The drill program is in its second ph ase and is focused on discovery and resource growth, including drilling targeting the potential for resource growth along strike at existing deposits along with diamond drilling targeting the higher-grade potential at depth. The primary goal of the completed first phase of the drill program was Reverse Circulation (“RC”) infill drilling for resource conversion to improve the confidence level of the existing Mineral Resource Estimate, with most of the first phase of the drill program allocated to the two largest deposits at Enchi, Boin and Sewum. 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.

In addition to drilling, a Pre-Feasibility Study (“PFS”) is underway and targeted for completion by the end of June 2026 (see news release dated February 5, 2026), alongside on-going development work in support of project advancement at Enchi which includes metallurgical testwork, hydrogeological testing, geotechnical work, and environmental work.

Boin Gold Deposit

Boin is one of the five deposits which comprise the Mineral Resource Estimate at Enchi (Boin has an Indicated Mineral Resource of 23.5 million tonnes grading 0.73 g/t Au containing 550,000 ounces and an Inferred Mineral Resource of 9.2 million tonnes grading 0.60 g/t Au containing 178,000 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.
