Newcore Gold Drilling Intersects 1.59 g/t Gold over 15.5 Metres, Including 3.22 g/t Gold over 6.4 Metres, at the Enchi Gold Project, Ghana
Highlights from Diamond Drilling at the Sewum Gold Deposit at Enchi
- Drilling intersected wide zones of gold mineralization above the mineral resource grade and outside the limits of the pit that constrains the Mineral Resource Estimate.
- Diamond drill hole SWDD107 intersected 1.59 g/t Au over 15.5 m from 147.5 m, with a higher-grade interval of 3.22 g/t Au over 6.4 m from 152.9 m.
- Hole SWDD108 intersected 0.48 g/t Au over 41.0 m from 141.5 m, with a second interval of 0.82 g/t Au over 18.5 m from 189.5 m including a higher-grade interval of 2.26 g/t Au over 4.5 m from 199.5 m.
- Drilling targeted shallow mineralization within a vertical depth of 140 metres at the Ridge Zone at Sewum, the northernmost area of the deposit.
- Hole SWDD112 intersected wide zones of near surface oxidized mineralization including 1.00 g/t Au over 10.5 m from surface and 0.69 g/t Au over 41.0 m from 21.5 m.
- Hole SWDD113A intersected 0.81 g/t Au over 16.8 m from 75.9 m, with a higher-grade interval of 2.41 g/t Au over 4.4 m from 76.6 m.
- Drill results not included in most recent Mineral Resource Estimate, with results highlighting potential for future resource growth at Enchi.
- Sewum is the largest deposit currently identified at Enchi and remains open along strike and at depth.
- This drilling reached a maximum vertical depth of only 140 metres, representing the deepest intercepts drilled to date at Sewum. Average vertical depth of all holes drilled to date at Sewum is only down to 95 metres.
Greg Smith, VP Exploration of Newcore stated, "We are excited to continue to unlock the future resource growth potential at Enchi through the drill bit. Initial results from diamond drilling completed at Sewum have extended gold mineralization below the pit-constrained mineral resource estimate released in March of this year, while also confirming near-surface lateral continuity in the adjacent sub-parallel structures. Importantly, although this drilling represents the deepest drilling completed to date at Sewum, holes only reached a maximum vertical depth of 140 metres, with the mineralized zone open at depth. The drilling also returned grades exceeding the mineral resource estimate grade both at surface and below the pits. With drilling ongoing and focused on defining the resource growth potential at depth and along strike, we are excited to continue to advance the district scale exploration opportunity at our Enchi Gold Project in Ghana."
This release reports results for 8 DD holes totalling 1,685 m (SWDD107 to SWDD114) targeting the Sewum Gold Deposit, with all holes intersecting gold mineralization. A total of 34,805 m in 256 holes has been reported as part of the ongoing drill program at Enchi, with 98% of holes intersecting gold mineralization.

Diamond Drilling at the Sewum Gold Deposit
SWDD107 to SWDD114 (8 DD holes totalling 1,685 m) were completed at Sewum, targeting mineralization within the shallow oxide-transition and the upper fresh mineral horizon at the Ridge Zone, with a goal of expanding the mineralized footprint of the deposit. This drilling reached a maximum vertical depth of 140 metres, representing the deepest intercepts drilled to date at Sewum, with prior drilling completed at Sewum focused on shallow mineralization within the first 100 vertical metres. The holes reported in this news release include six holes testing four sections along a 500 metre strike length on the upper structures and another two holes testing two sections along a 100 metre strike length in the lower structures of the zone.
Three diamond drill holes totalling 733 m (SWDD107 to SWDD109) were drilled on the same section and used to define the dip of the main sub-parallel gold mineralized structures at depth. Hole SWDD107 intersected 1.59 g/t Au over 15.5 m from 147.5 m, including a higher-grade interval of 3.22 g/t Au over 6.4 m from 152.9 m. Hole SWDD108 intersected the main structure with 0.48 g/t Au over 41.0 m from 141.5 m, as well as a second mineralized zone that intersected 0.82 g/t Au over 18.5 m from 189.5 m including a higher-grade interval 2.26 g/t Au over 4.5 m from 199.5 m. Hole SWDD109 intersected 0.93 g/t Au over 11.05 m from 145.95 m including a higher-grade interval of 1.81 g/t Au over 4.0 m from 151.0 m.
Two diamond drill holes totalling 312 m (SWDD112 and SWDD113A) tested the western structures near the base of the Ridge Zone and intersected both near-surface oxidized mineralization as well as gold mineralization in the upper fresh mineralization. Hole SWDD112 intersected 0.69 g/t Au over 41.0 m from 21.5 m in the oxide mineralization including a higher-grade interval of 1.41 g/t Au over 4.0 m from 46.5 m and 2.08 g/t Au over 3.0 m from 57.5 m. This hole also intersected oxidized mineralization from surface with 1.00 g/t Au over 10.5 m as well as a third deeper zone within the fresh mineralization with 0.41 g/t Au over 25.2 m from 102.4 m. Hole SWDD113A, collared 100 metres to the north, intersected 0.81 g/t Au over
16.8 m from 75.9 m including a higher-grade interval of 2.41 g/t Au over 4.4 m from 76.6 m.
Diamond drill hole SWDD110, totalling 225 m and collared 50 metres north of hole SWDD109, intersected 0.60 g/t Au over 21.2 m from 185.8 m. Hole SWDD111, totalling 155.6 m and collared 50 metres north of hole SWDD114, intersected gold mineralization but was lost before reaching the primary target.
Diamond drilling completed at Sewum continues to confirm continuity along strike and down dip for the principal structures which comprise the Ridge Zone of the Sewum Gold Deposit.
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 phase 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.
Sewum Gold Deposit
Sewum is one of the five deposits which comprise the Mineral Resource Estimate at Enchi (Sewum has an Indicated Mineral Resource of 41.2 million tonnes grading 0.43 g/t Au containing 573,000 ounces and an Inferred Mineral Resource of 24.2 million tonnes grading 0.39 g/t Au containing 308,000 ounces). Sewum is located 15 kilometres south of the town of Enchi, with nearby roads and power and further access provided by a series of drill roads. Sewum is outlined on surface by a greater than six-kilometre-long and one-to-two-kilometre-wide gold-in-soil anomaly. An airborne geophysical anomaly coincident with the Sewum Gold Deposit defines a series of subparallel and intersecting structures. To date, approximately 45% of the gold-in-soil anomaly at Sewum is untested by drilling, with the average vertical depth of all holes drilled to date at Sewum only down to 95 metres.
