Drilling on the Nyam Gold Deposit Continues to Encounter Multiple Wide Zones of Gold Mineralization, Including High-Grade Structures
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. Drilling at the Nyam Gold Deposit ("Nyam") at Enchi has intersected high-grade, oxide gold mineralization grading 2.04 grams per tonne gold ("g/t Au") over 35.0 metres ("m") from surface, including 4.89 g/t Au over 8.0 m from 8 m. Drilling at Nyam continues to encounter higher-grade gold mineralization from surface, with wide zones encountered in both the oxide and sulphide mineralization. These results also tested the southern extension at Nyam, increasing the drill tested strike extent at Nyam to three kilometres.
Highlights from Drilling at Nyam
- Drilling on the southern portion of Nyam encountered multiple wide zones of near surface gold mineralization, including high-grade cores.
- Hole NBRC075 intersected, from surface, an oxidized high-grade gold mineralized structure grading 2.04 g/t Au over 35.0 m, including 4.89 g/t Au over 8.0 m from 8 m.
- Hole NBRC073 intersected 0.78 g/t Au over 57.0 m from 74 m (sulphide zone).
- Hole NBRC076 intersected 0.85 g/t Au over 50.0 m from 1 m (oxide zone transitioning to sulphide zone), including 1.18 g/t Au over 13.0 m from 1 m and 2.10 g/t Au over 8.0 m from 31 m.
- Drilling on the central portion of Nyam tested oxide and sulphide mineralization and encountered multiple zones of shallow high-grade gold mineralization.
- Hole NBRC087 intersected a high-grade gold mineralized structure in the sulphide zone grading 2.14 g/t Au over 19.0 m from 84 m, including 4.14 g/t Au over 2.0 m from 92 m.
- Hole NBRC088 intersected 0.88 g/t Au over 28.0 m from 57 m, including 5.09 g/t Au over 2.0 m from 80 m (sulphide zone).
- Drilling targeting the oxide zone continued to return strong results, with hole NBRC085 intersecting 1.26 g/t Au over 18.0 m from surface and hole NBRC086 intersecting 1.24 g/t Au over 19.0 m from 17 m.
- Step out holes completed to test the southern extent of Nyam have extended the drill tested portion of the Nyam structure by 800 metres to the south.
- Hole NBRC066, drilled 800 metres south of the current resource pit, intersected 0.52 g/t Au over 15.0 m from 89 m (sulphide zone).
- Results from 59,559 metres of the total 90,000 metre drill program have been received and released. Drilling continues at Enchi with recent drilling testing Eradi and Sewum South, gold targets with no defined mineral resource.
Luke Alexander, President and CEO of Newcore stated, "Drilling at Nyam continues to deliver strong results, demonstrating the potential for resource growth across our Enchi Gold Project. We have increased the strike extent of drilled mineralization at Nyam with mineralization now intersected along more than three kilometres of strike length, remaining open along strike and at depth. We also continue to encounter shallow, higher-grade gold mineralization at Nyam with drilling intersecting wide zones of mineralization in both the oxides and sulphides. Given the success we have achieved to date with drilling at Nyam, we will continue to test the potential to grow the shallow oxide resource at this deposit while testing the potential for higher-grade mineralization at depth."
This news release reports results for 34 Reverse Circulation ("RC") holes totalling 5,245 m (NBRC056 to NBRC089) targeting the Nyam Gold Deposit, with 30 of the 34 holes intersecting gold mineralization.

A series of holes were also completed testing the southern extension of the structure 800 metres to the south. Step out holes to the south have extended the drill tested portion of the Nyam structure to three kilometres. Hole NBRC066 drilled 800 metres south of the existing pit constrained resource intersected 0.52 g/t Au over 15.0 m from 89 m (sulphide zone). Additional results from this step out drilling included hole NBRC059B which intersected 1.60 g/t Au over 10.0 m from 97 m (sulphide zone) and hole NBRC058 which intersected 1.11 g/t Au over 2.0 m from 17 m (oxide zone).
For the total planned 90,000 metre drill program, assay results have now been received and released for 350 holes representing 59,559 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 83 holes totalling 12,649 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.
