Magna Mining Intersects 3.8% Nickel, 1.8% Copper, & 0.5 g/t PT+PD+AU over 10.8 Metres, Including 6.0% Nickel, 0.3% Copper, & 0.7 g/t Pt+PD+AU over 5.8 Metres
Sudbury, Ontario–(Newsfile Corp. – December 12, 2022) – Magna Mining Inc. (TSXV: NICU) (“Magna” or the “Company”) is pleased to announce that first assays have been received from the recent drilling at Crean Hill. Drillhole MCR-22-003 intersected massive sulphide mineralization (see news release dated November 17th, titled “Magna Mining Provides Update on Activities at Crean Hill), grading 6.0 % Ni, 0.3 % Cu, 0.7 g/t Pt+Pd+Au over 5.8 metres. The Company has completed 10 drillholes to date and expects to resume diamond drilling in early January, 2023.
Drillhole MCR-22-003, intersected 3.8% Nickel, 1.8% Copper, & 0.5 g/t Pt+Pd+Au over 10.8 metres, including 3.2% Ni, 8.3% Cu, & 0.5 g/t Pt+Pd+Au over 1.7 metres, and 6.0% Ni, 0.3% Cu, 0.7 g/t Pt+Pd+Au over 5.8 metres in the 101 FW Zone
101 FW Zone mineralization hosted within an approximately 70 metre wide footwall breccia package which remains open for exploration
2,022 metres completed to date in 10 drillholes on the Crean Hill property. All drillholes have intersected significant mineralization as expected
Jason Jessup, Chief Executive Officer for Magna, commented, “We are excited to announce initial assay results from our current drilling at Crean Hill. Drillhole MCR-22-003 was our first drillhole testing the 101 FW Zone mineralization, and demonstrates the quality and grade of the resources remaining at Crean Hill. Additional assay results are expected in early January and will be announced shortly thereafter.”
The initial drilling program consisted of 10 drillholes, totaling 2022 metres, and was targeting areas that will be considered for advanced exploration and potential bulk sampling within the current Mineral Resources (Figures 1 and 2). Assay results received to date are summarized in Table 1.
Four drillholes, MCR-22-003 to MCR-22-006, targeted the 101 zone below historical mining. This area was not a focus of previous Lonmin Canada Inc. (“Loncan”) drilling as it is not considered a low-sulphide, high PGE system. The 101 FW Zone consists of disseminated to locally massive sulphide, hosted within a footwall breccia system, extending southwest into the footwall of the Intermediate Zone (Figure 3 and 4). Sudbury footwall orebodies are commonly hosted within breccia systems, and often are elevated in Ni, Cu and PGE mineralization, relative to typical SIC contact mineralization. Drillhole MCR-22-003 was targeting below and adjacent to historically mined stopes and confirms the mineralization continues down-dip and along strike to the southwest. The drillhole intersected approximately 70 m of footwall breccia, with local disseminated to stringer mineralization throughout. Significant assay results received to date include 3.8% Ni, 1.8% Cu, 0.5 g/t Pt+Pd+Au over 10.8 metres. The 101 FW Zone breccia system remains open for exploration and expansion to the southwest and down-dip of the historical mining. In addition to the 101 FW Zone, Drillhole MCR-22-003 intersected 0.7% Ni, 0.4% Cu, 0.6 g/t Pt+Pd+Au over 30.2 metres, including 1.1% Ni, 0.6% Cu, 1.4 g/t Pt+Pd+Au over 10.5 metres within the Intermediate Zone at the base of the Sudbury Igneous Contact (“SIC“).
Five drillholes, MCR-22-001, MXR-22-002 and MCR-22-007-009, were completed on the near surface portion of the Intermediate Zone, within the current open pit resource (Figure 2). The Intermediate Zone is a zone of contact Ni-Cu mineralization at the base of the SIC and hosted within Sublayer Norite. Assays are pending.
One hole, MCR-22-010 targeted the 109 FW Zone. The 109 FW Zone is a zone of disseminated to semi-massive sulphide, hosted within footwall breccia, extending into the footwall of the Main Zone (Figure 2 and 3). The 109 FW Zone was defined near surface by Loncan, and is considered a low-sulphide, high PGE Footwall zone. This style of mineralization can have very high Pt+Pd+Au grades over significant widths, as demonstrated by historical Loncan drillhole LM05060, which intersected 0.6 % Cu, 0.3% Ni, 2.5 g/t Pt, 20.1 g/t Pd, 10.2 g/t Au (33.5 g/t TPM) over 18.5 metres and drillhole LM03061, which intersected 0.4 % Cu, 0.9% Ni, 31.1 g/t Pt, 4.5 g/t Pd, 1.8 g/t Au (37.5 g/t TPM) over 17.4 metres. The 109 FW Zone has been defined to approximately 750 ft level below surface, and wide spaced drilling below this elevation suggest the high grade PGE Footwall mineralization continues to depth extending into the footwall from the Main Zone.
