Drill Results from Step Out Drilling on the Boin Gold Deposit and Positive Metallurgical Results from Bottle Roll Tests on the Boin and Sewum Gold Deposits
Vancouver, BC – Newcore Gold Ltd. ("Newcore" or the "Company") (TSX-V: NCAU) is pleased to provide an update on the work program underway at the Company’s 100% owned Enchi Gold Project ("Enchi" or the "Project") in Ghana, including additional results from the ongoing 58,000 metre drill program and results of metallurgical testwork. Drilling has intersected 1.27 grams per tonne gold ("g/t Au") over 27.0 metres ("m") from 27 m at the Boin Gold Deposit ("Boin") at Enchi, with results extending Boin along strike. Newcore is also pleased to announce positive metallurgical results from bottle roll tests completed on the Boin and Sewum Gold Deposits, with samples achieving an average gold recovery of 89.4%.
•Drill results from the additional holes drilled at Boin include: ?Hole KBRC163 intersected 1.27 g/t Au over 27.0 m from 27 m to 54 m (oxide zone).
?Hole KBRC169 intersected 1.41 g/t Au over 14.0 m from 55 m to 69 m, including 2.86 g/t Au over 6.0 m from 62 m to 68 m (oxide zone).
?Hole KBRC175 intersected 0.65 g/t Au over 22.0 m from 67 m to 89 m (oxide zone).
•Metallurgical testing returned an average gold recovery of 89.4%. Bottle roll testing completed on material from the Boin and Sewum Gold Deposits.
•Drilling on the Project continues with three rigs currently on site, and an additional two rigs anticipated to be on-site by the end of January.
Luke Alexander, President & CEO of Newcore stated, "We continue to have strong results from the drilling that is underway at our Enchi Gold Project in Ghana. These results followed-up on the initial positive results we released in 2020 from Boin and continue to extend the deposit along strike, reinforcing the potential for resource growth at our existing deposits at Enchi. To date we have released results for less than 25% of the total planned 58,000 metre program that is underway, and as such we look forward to continuing to prove out the potential of our district-scale Project."
Greg Smith, Vice President of Exploration of Newcore stated, "Drilling at the Boin Gold Deposit at Enchi continues to extend the strike length of the deposit, with further drilling on this area planned in 2021 as we accelerate the pace of our drill program. The results of the metallurgical testwork continue to confirm the excellent characteristics of the oxide material with an average recovery of 89.4% achieved from 24-hour bottle roll tests completed on 49 samples taken from our two primary resource areas at Enchi, the Boin and Sewum Gold Deposits."
This news release highlights 25 holes targeting the Boin Gold Deposit. The 25 holes (3,950 m) drilled at Boin extended the zone along strike intersecting both wide gold mineralized zones and multiple sub-parallel structures. Additional drilling is planned at Boin in 2021 to follow-up on these results.
A total of 18,149 metres in 113 holes have been completed as part of the ongoing 2020 - 2021 drill program at Enchi. For the total planned 58,000 metre drill program, assay results have now been received and released for 88 holes representing 13,722 metres (25 holes totalling 3,950 metres reported in this news release in addition to previously released results – 19 holes on December 15, 2020, 8 holes on November 26, 2020, 10 holes on November 10, 2020, 13 holes on October 21, 2020 and 13 holes on September 28, 2020).

Enchi hosts a pit constrained National Instrument 43-101 ("NI 43-101") Inferred Mineral Resource of 52.9 million tonnes grading 0.72 g/t Au containing 1.22 million ounces gold (see Newcore news release dated September 14, 2020). The Company filed a NI 43-101 compliant technical report in support of the updated mineral resource estimate on October 28, 2020.
The 2020 metallurgical testwork for the Enchi Gold Project consisted of a series of bottle roll tests completed by Intertek Minerals Limited on 49 representative oxide samples from the ongoing drill program. These samples focused on Boin (20 samples) and Sewum (29 samples), the two gold deposits on the Project that currently represent the majority of the NI 43-101 Inferred Mineral Resource.
An average gold recovery of 89.4% was achieved from 24-hour bottle roll tests, with 43 of the 49 samples achieving a recovery greater than 75%. The samples from Boin had an average recovery of 91.4% (17 of the 20 samples had a recovery greater than 75%), and the samples from Sewum had an average recovery of 88.8% (26 of the 29 samples had a recovery greater than 75%).
Samples were selected from the 2020 drilling to include a range of gold grades, weathering intensities (closely related to depth), as well as different areas of each deposit. Most of the samples (38 of 49) were selected from the moderately and highly weather categories which represent the largest component of the weathered profile at Enchi, with those samples achieving an average recovery rate of 91.5% (34 of the 38 samples had a recovery greater than 80%). No significant relationship was noted between the recovery rate and the sample grade or sample depth. Further metallurgical testing is ongoing as part of the current work program at Enchi.
2020 - 2021 Enchi Drilling Program
A 58,000 metre discovery and resource expansion drilling program is underway at Enchi. The program includes both RC and diamond drilling and will include the first deep 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 Boin, Sewum, and Nyam Deposits. Additional drilling is planned at previously drilled zones that are outside of the resource area (Kojina Hill, Kwakyekrom 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.
Boin Gold Zone
The Boin Gold Deposit is one of the primary deposits currently included in the NI 43-101 Inferred Mineral Resource Estimate at Enchi. Boin 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. Boin is outlined on surface by a five-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 two kilometres north and five kilometres south beyond the limits of current drilling.
