Vancouver, BC – Newcore Gold Ltd. ("Newcore" or the "Company") (TSX-V: NCAU, OTCQX: NCAUF) is pleased to announce additional drill results from the 90,000 metre drill program underway at the Company’s 100% owned Enchi Gold Project ("Enchi" or the "Project") in Ghana. Diamond drilling at the Nyam Gold Deposit ("Nyam") at Enchi has intersected high-grade gold mineralization at depth grading 4.51 grams per tonne gold ("g/t Au") over 13.0 metres ("m") from 236 m and 3.21 g/t Au over 15.0 m from 321 m.
Highlights from Diamond Drilling at Nyam
- Deeper diamond drilling on the southern extent of Nyam in the sulphide zone encountered high-grade gold mineralization in down dip, step out holes, including:
- Hole NBDD048 intersected 4.51 g/t Au over 13.0 m from 236 m, including 7.40 g/t Au over 7.7 m from 237.5 m.
- Hole NBDD056 intersected 1.62 g/t Au over 24.8 m from 248.7 m, including 3.17 g/t Au over 9.0 m from 248.7 m.
- Hole NBDD055 intersected 1.57 g/t Au over 8.0 m from 276 m, including 2.64 g/t Au over 2.2 m from 279 m.
- Hole NBDD051 intersected 4.57 g/t Au over 2.0 m from 274 m.
- Drilling on the central portion of Nyam, targeting sulphide mineralization, also encountered high-grade gold mineralization in down dip, step out holes, including.
- Hole NBDD052 intersected a high-grade gold mineralized structure grading 5.57 g/t Au over 8.0 m from 322 m, within a broader zone of 3.21 g/t Au over 15.0 m from 321 m.
- Hole NBDD053 intersected 1.54 g/t Au over 8.9 m from 291.2 m, including 3.78 g/t Au over 1.8 m from 291.2 m and 4.20 g/t Au over 1.0 m from 297 m.
- To date, deeper drilling at Nyam has defined two northerly plunging high-grade zones with strike lengths of up to 500 m and extending to depths of up to 300 m that remain open for further expansion.
- The Nyam Gold Deposit, one of four gold deposits defined to date at Enchi, has been outlined by drilling for over 1.8 kms and remains open along strike and at depth.
Luke Alexander, President and CEO of Newcore stated, "We are extremely pleased with the continued success from our ongoing 90,000 metre drill program, with these latest results from Nyam continuing to demonstrate the potential for higher-grade mineralization at depth. Drilling continues to intersect high-grade structures at all the defined deposits at Enchi, with all deposits remaining open along strike and at depth. We look forward to continuing to advance our understanding of the potential at Enchi through the drill bit, an asset that is located in a prolific and well-known district that hosts multi-million-ounce gold mines."

Hole NBDD048, drilled on the southern end of the current resource pit at Nyam, intersected 4.51 g/t Au over 13.0 m from 236 m, including 7.40 g/t Au over 7.7m from 237.5 m. This hole was drilled below the section where RC hole NBRC017 intersected shallow oxide mineralization of 1.38 g/t Au over 45 m from 8 m, including 6.25 g/t Au over 6 m from 47 m. Additional holes on the same section include previously released holes NBRC024 (1.34 g/t Au over 27 m from 57 m and 3.45 g/t Au over 9 m from 93 m) and NBRC027 (2.83 g/t Au over 6 m from 3 m). Hole NBDD056 collared 75 metres north of NBDD048 and approximately 10 metres downdip of NBDD048 intersected 1.62 g/t Au over 24.8 m from 248.7 m, including 3.17 g/t Au over 9 m from 248.7 m and a second interval of 0.67 g/t Au over 13 m from 278 m.
Hole NBDD055 collared 75 metres north of NBDD056 intersected 1.57 g/t Au over 8 m from 276 m, including 2.64 g/t Au over 2.2 m from 279 m. Hole NBDD051, drilled 100 metres south of hole NBDD048 and beyond the southern limit of the current pit constrained resource at Nyam, intersected 4.57 g/t Au over 2.0 m from 274 m and 0.65 g/t Au over 12 m from 254 m, extending the drill tested extent of the gold mineralization by 175 metres to depth below the resource pit.
Hole NBDD052, which intersected 3.21 g/t Au over 15 m from 321 m including 5.57 g/t Au over 8 m from 322 m, was drilled 150 metres north of NBRC047 (previously released results contained high-grade gold mineralization of 1.94 g/t Au over 25 m from 222 m, including 5.78 g/t Au over 7 m from 227 m). This hole represented a 100 metre step out and a down dip extension of the gold structure at Nyam. Hole NBDD053 was drilled 75 metres south of NBDD052 and tested an up-dip portion of the structure. NBDD053 intersected 1.54 g/t Au over 8.9 m from 291.2m, including 3.78 g/t Au over 1.8 m from 291.2m, confirming the continuity of the high-grade gold mineralization.
The deeper diamond drilling at Nyam has defined two northerly plunging higher-grade zones within the Nyam gold zone. The southern high-grade zone which is defined along 350 metres of strike length, and to a depth of 250 metres vertically, includes near surface intercepts in RC holes NBRC017, NBRC024, and NBRC027 and deeper mineralized intervals in diamond drill holes NBDD048, NBDD055, and NBDD056. The central high-grade zone, which is defined along 500 metres of strike length and to a vertical depth of 300 metres, includes previous intercepts in numerous shallow RC holes: down dip RC holes NBRC045 and NBRC047, and deeper mineralized intervals in diamond drill holes NBDD052, NBDD053, and NBDD054. Additional drilling is planned at Nyam to follow-up on these results.
For the total planned 90,000 metre drill program, assay results have now been received and released for 359 holes representing 62,870 metres.
Enchi Gold Project Mineral Resource Estimate
The Enchi Gold Project hosts a pit constrained Inferred Mineral Resource of 70.4 million tonnes grading 0.62 g/t Au containing 1.41 million ounces gold (see Newcore news release dated June 8, 2021). 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 was prepared by independent qualified person Todd McCracken, P. Geo. of BBA E&C Inc. The technical report, titled "Preliminary Economic Assessment for the Enchi Gold Project, Enchi, Ghana" has an effective date of June 8, 2021, and is available under the Company’s profile on SEDAR at www.sedar.com.
2020 - 2021 Enchi Drilling Program
A 90,000 metre discovery and resource expansion drilling program is underway at Enchi. The program includes both RC and diamond drilling and will include the first deeper drilling planned on the Project. This drill program includes testing extensions of the existing resource areas while also testing a number of high priority exploration targets outside of the Inferred Mineral Resource. Drilling is focused on step out extensions and exploration drilling at the Sewum, Boin, Nyam and Kwakyekrom Deposits. Additional drilling is planned at previously drilled zones that are outside of the resource area (Kojina Hill and Eradi), along with first pass drilling to test a series of kilometre-scale gold-in-soil anomalous zones with no prior drilling (Nkwanta, Sewum South and other anomalies). All zones represent high priority targets based on geological, geochemical and geophysical surface work and previous trenching and drilling.
Nyam Gold Zone
The Nyam Gold Deposit is one of the four deposits which comprise the pit constrained Inferred Mineral Resource Estimate at Enchi (4.9 million tonnes grading 0.82 g/t Au containing 129,000 ounces). Nyam 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. An airborne geophysical anomaly coincident with the Nyam Gold Deposit shows a complex series of linear high conductivity trends, reflective of the multiple sub-parallel gold-bearing structures. As part of the 2020 - 2021 drill program, a total of 101 holes totalling 17,120 metres have been completed at Nyam.

(2) Notes for Inferred Mineral Resource Estimate:
- CIM definition standards were followed for the resource estimate.
- The 2021 resource models used ordinary kriging (OK) grade estimation within a three-dimensional block model with mineralized zones defined by wireframed solids and constrained by pits shell for Sewum, Boin and Nyam. Kwakyekrom used Inverse Distance squared (ID2).
- A base cut-off grade of 0.2 g/t Au was used with a capping of gold grades varied by deposit and zone.
- A US$1,650/ounce gold price, open pit with heap leach operation was used to determine the cut-off grade of 0.2 g/t Au. Mining costs of US$1.40 for oxide, US$2.10 for transition, and US$2.60 for fresh rock per mined tonne and G&A and milling costs of US$6.83/milled tonne. The Inferred Mineral Resource Estimate is pit constrained.
- Metallurgical recoveries have been applied to four individual deposits and in each case three material types (oxide, transition, and fresh rock) with average recoveries of 77% for Sewum, 79% for Boin, 60% for Nyam and 72% for Kwakyekrom.
- A density of 2.20 g/cm3 for oxide, 2.45 g/cm3 for transition, and 2.70 g/cm3 for fresh rock was applied.
- Optimization pit slope angles varied based on the rock types.
- Mineral Resources that are not mineral reserves do not have economic viability. Numbers may not add due to rounding.
