The interpretation of the results from the 2019-2020 drill programme strengthens the Company's vision to extend mine life and demonstrate the continuity of underground ore deposits. Minto is now working on a National Instrument 43-101 Preliminary Economic Assessment Report (PEA), which will incorporate the results from the 2019 - 2020 drilling campaign. The report is expected to be released in Q2 2021. Minto is planning an exploration drill programme for 2021 with the objective of further expanding resources and advancing numerous high-priority near-mine and regional targets in the Minto Copper Belt.
Minto North II
The Minto North II deposit is located southeast from the Minto North open pit. The Minto North ore body is the highest-grade deposit on the property and was mined out by open-pit in 2016, which made the Minto North II drill target a high-priority. The main purpose of the drill programme was to confirm the location of the ore body and its extent as there were only 10 historic drill holes drilled prior to the 2020 programme. The 2020 drill programme was completed on 25m to 30m drill spacing totalling 5,609 meters with 31 drill holes with NQ diameter.
The phase I drill programme focused on the central portion of the ore body. Results of the phase I programme indicated that the Minto North II ore body is a flat-lying, shallow lens that lies about 175 metres below surface and approximately 90 metres to the east from the Minto North ore body. Due to the successful results of the phase I programme, the second phase was targeting the extension and definition of the ore body to the south and to the east based on information obtained from a high-resolution MAGTM drone survey in combination with a 3D inverted Titan 24 DC-IP geophysical survey. The phase II drilling results indicate that the Minto North II ore body extends to the south and is cut off by a major NNW-trending fault to the east.

Copper Keel South
The Copper Keel South lens is located southwest from the Copper Keel Main mining area. The Copper Keel South deposit was drilled to test its extension towards the southwest due to its proximity to the Copper Keel Main lens, which accounts for most of the current production stopes at the mine. Surface drilling consisted of 15 drill holes in NQ diameter, totaling 3,816 metres.
The 2020 drill programme confirmed that the Copper Keel South deposit is a northwest trending ore body that consists of multiple stacked lenses. The largest and upper most lens gently dips towards the east and extends back to the Copper Keel Main mining area, therefore it likely represents the upward western continuation of the Copper Keel Main ore body.

Copper Keel West
The Copper Keel West lens lies west of the Copper Keel Main production area. A total of 5 NQ drill holes, totaling 2,211 metres were drilled targeting gaps of coverage in the ore lens. Five drill holes with a total of 2,211 metres were drilled. Due to difficult ground conditions and overburden this surface programme was shortened and substituted with an underground drilling programme which consisted of 2,618 metres and 12 diamond drill holes with NQ diameter to fill the gaps of coverage caused by the difficult drilling conditions on surface. An additional 2 condemnation drill holes (156m) were also completed from underground.

Copper Keel North
The Copper Keel North deposit is located north of the Copper Keel Main mining area. A total of 11 drill holes, 4,848 metres of surface drilling was conducted on the Copper Keel North area with the aim to define and expand the lens towards the north. Due to the promising results of the surface programme, the focus of the underground drilling was to test the extension of the deposit to the north and to infill the gaps in the central portion of the lens. The programme consisted of 6 NQ drill holes, totalling 1,161 metres.
While the underground assays are currently pending and will be communicated in a future news release, the results of the surface programme indicate that the Copper Keel North deposit lies to the north approximately 100 to 150 metres below the Copper Keel Main area. The Copper Keel North deposit is open to the north where we have a highly prospective area that coincides with the right geophysical anomalies and will be tested during the 2021 drill programme.

Assays from the Copper Keel North underground drill programme are currently pending.
Gati Al-Jebouri, Chief Executive Officer and Chairman of the Board said:
"The extensive drilling programme was carried out during a difficult period with significant limitations due to the Covid 19 pandemic. The Minto team have done an excellent job to complete the 2019/20 drilling programme on budget and with a limited delay that was mainly due to the challenges of getting core samples to laboratories for testing and assay production. I am grateful to the Minto team and in particular to the geologists for executing this task efficiently. The initial results, that Minto is continuing to process, and I trust will enable them to produce a PEA by Q2 encourage me to believe that the Minto project has significant potential for mine life extension and value creation. I am looking forward to reviewing the PEA, which should show the true value of Minto."
