Magna Mining announces high-grade intercepts near surface at Crean Hill

Global Mining Review,
Magna Mining Inc. has released initial assays from a series of short, near surface drillholes immediately beneath the surface exposure of the 109 Footwall (FW) Zone. The assay results reported wide, high- grade intercepts including 0.7% Ni, 0.6% Cu, and 8.7 g/t Pt + Pd + Au over 31 m in hole MCB-23-003, and 0.3% Ni, 0.8% Cu, and 9.0 g/t Pt + Pd + Au over 21 m in hole MCB-23-007. These high-grade intersections are not well represented in the current resource model. As a result of confirming high-grade mineralisation in this section of the 109 FW Zone, Magna is now planning a surface, advanced exploration bulk sample programme to better define the grade and continuity of mineralisation in this area. Results for 16 of 26 short drillholes completed have been received so far.
Highlights from the new assay results include:
- MCB-23-003: 0.7% Ni, 0.6 % Cu, 8.7 g/t Pt + Pd + Au over 31.0 m, including 5.9 % Ni, 2.0% Cu and 12.4 g/t Pt + Pd + Au over 3.2 m.
- MCB-23-007: 0.3% Ni, 0.8 % Cu, 9.0 g/t Pt + Pd + Au over 21.0 m including 1.9 % Ni, 1.5% Cu and 49.1 g/t Pt + Pd + Au over 1.9 m.
- MCB-23-012: 0.4% Ni, 0.6 % Cu, 18.9 g/t Pt + Pd + Au over 13.0 m including 0.8 % Ni, 1.1% Cu and 44.9 g/t Pt + Pd + Au over 4.9 m.
Jason Jessup, CEO of Magna stated, “The assay results reported today are part of a definition drilling programme to improve our understanding and modelling of the 109 FW Zone. The intersections received to date support our new thesis that there are, high grade, structurally controlled systems running through the 109 FW Zone. These high-grade trends are not well represented in the current Mineral Resource Estimate but will be incorporated into future resource updates. Magna is currently planning an advanced exploration bulk sampling programme at surface from this area of the 109 FW Zone. We are expecting to complete this bulk sample before the end of this year in advance of a possible underground advanced exploration programme in early 2024.”
The 109 FW Zone is considered a low sulphide, high-grade Pt + Pd + Au mineralised zone, hosted within a breccia system extending southwest from the historically mined Main Zone contact Ni-Cu orebody. Magna drilling in 2022 and early 2023 identified extremely high-grade, semi-massive to massive sulphide mineralisation within the overall low sulphide mineralised zone. A programme comprised of 26 short (15 – 50 m) drillholes has been completed, with the objective of defining the distribution and continuity of semi-massive to massive sulphides. At least two structurally controlled, high grade trends have been recognised within the 109 FW Zone, which will improve the geological modelling and will be incorporated into future resource estimates. These trends are not well exposed on surface and a surface advanced exploration bulk sampling programme is being planned to confirm and better define the interpreted high-grade trends, and to facilitate planning of future exploration to expand on the 109 FW Zone.
