Class 1 Nickel and Technologies Ltd. announced progress of the Phase 1 drilling program at Dundonald South Deposit, on the Alexo-Dundonald Nickel Sulphide Property, 45 km northeast of the City of Timmins, Ontario (Canada). The objective of the program is to drill test targets in the vicinity of the known Dundonald South mineralized zones. The Phase 1 program was designed from three-dimensional modelling and interpretation of extensive historical drilling and BHEM survey databases. The Company is delighted to report that the Phase 1 drilling intersected massive sulphide mineralization at Dundonald South. The Phase 1 program at Dundonald South is focused on drill testing parallel and extensional BHEM targets near known mineralization. Massive sulphide mineralization was intersected in two of the first three holes drilled: hole DS-21-006 and hole DS-21-005. The sulphide mineralization is indicated to be nickeliferous by hand-held XRF analysis. The third drill hole, DS-21-008, intersected semi-massive nickel sulfides near-surface. The Phase 2 drilling at Dundonald South will follow the same priorities as previously to the northeast at Alexo North and South: 1) expanding the Mineral Resources by following-up on drill intersections and BHEM-generated targets from the Phase 1 drilling; 2) infill drilling to advance Inferred Mineral Resources to Indicated Mineral Resources; and 3) testing new and under-tested, priority geophysically-generated targets on the Alexo-Dundonald Property. Phase 2 will commence in late summer 2021 and is fully funded by the Company treasury.
