Midnight Sun Mining Corp. released the initial results from drilling conducted on its Solwezi Licences during 2022. The Solwezi Licences are located immediately southwest of First Quantum's Kansanshi Copper Mine, the larger copper mining complex in Zambia.

Midnight Sun's 2022 exploration program was designed to validate and confirm new structural control models for upgraded stratabound copper mineralization in different areas of known mineralization on the Solwezi Licences. The new structural control models were developed in-house following a review and re-interpretation of past exploration work and new high-resolution geophysical data over the project area. During the 2022 Solwezi field season, Midnight Sun has completed 12 drill holes totaling 2,639 metres of core with two additional drill holes currently in progress.

Drilling has been on the Mitu Trend and on the Crunch Zone Prospect. The Company intends to continue field work as long as weather conditions permit. For the balance of the 2022 field season, the Company's work will focus on gaining a better understanding of the newly identified Kansanshi-style mineralization on the Mitu Trend.

The Mitu Trend targets were developed based on the interpretation of airborne magnetic data which highlighted a corridor of intense deformation, about 8 ­ 10 kilometres wide, that includes numerous northeast-trending structures which are also key to mineralization at the Kansanshi Mine. Five widely spaced diamond drill holes were completed on the Mitu Trend targeting northeast-trending mineralization settings at two localities within the wider Mitu Trend. Drill holes MTDD-044 and MTDD-045 are located approximately 500 metres apart and intersected structurally controlled Cu-Co mineralization including: 4.15m @ 2.28% Cu eq (1.29% Cu & 0.13% Co & 0.09% Ni) from 113.5m, in MTDD-044; 5.80m @ 2.41% Cu eq (1.86% Cu & 0.07% Co & 0.02% Ni) from 119.2m, in MTDD-044; and 7.30m @ 0.79% Cu eq (0.58% Cu & 0.02% Co & 0.02% Ni) from 149.0m, in MTDD-045.

Holes drilled to test the continuity of the historic intercept in hole MDD-17-15 which measured 4.23% CuEq over 11.6m achieved a technical success, encountering sulphide minerals in fault breccia and the associated alteration zones broadly within the target depth interval. A detailed assessment is underway to assess the complexity of the setting in which this discovery was made. Crunch Zone: The Crunch Zone exploration target is situated between the Kazhiba Dome in the northwest and the Solwezi Dome in the southeast.

Based on geophysical data, it appears a northeast trending wedge of Copperbelt strata is `crunched' between the domes showing interference fold patterns that abruptly terminate against the domal structures. An analysis of the VTEM electromagnetic survey suggest mineralized fluids may have migrated along major faults or thrusts which occurred where the Copperbelt strata encountered the dome structures. An initial drill program consisting of several drill traverses to test for mineralization as well as determining the rock succession in the contact zones is underway at the Crunch Zone with seven holes completed.

No assays from these holes have been received yet.
