MAGMATIC SULFIDE MINERALIZATION IDENTIFIED IN THE FOOTWALL OF THE SHAKESPEARE DEPOSIT AT BIRD’S BANE: ASSAYS HIGHLIGHT THE POTENTIAL FOR A NEW MINERAL ZONE BENEATH THE FOOTWALL MEGABRECCIA UNIT
Sudbury, Ontario, February 4, 2020 – Magna Mining Corporation (“Magna Mining” or the “Company”) reports 2.21 gpt TPM including 1.07 gpt Pd over 1.22m channel samples at the Bird’s Bane occurrence up-dip from mineralization at depth.
The new results are from a trenching program carried out as follow up to an anomalous surface sample 355561 which carried 0.04% Ni, 0.32% Cu, 0.62 gpt Pt, & 1.24 gpt Pd. Channel samples were taken from a >5m wide mineralized zone but early snowfall prevented additional follow-up in 2019.
Geological relationships
The footwall rocks of the Deposit comprise a megabreccia of >1m diameter blocks of unmineralized Nipissing Gabbro within a matrix of melanocratic gabbro containing magmatic Ni-Cu-Co-PGE sulfide mineralization. The Bird’s Bane trench is situated to the south of this unit in the footwall of the Deposit, and the assays record a style of mineralization with slightly higher Pd/Pt than the Deposit. Minimal exploration has been completed in the footwall of the Shakespeare Deposit, but a combination of geological and geophysical observations indicate potential for the discovery of mineralization in dense mafic rocks that correlate with a gravity feature.
Mineralization
In June 2019 a grab sample in the Bird’s Bane area returned 0.04% Ni, 0.32% Cu, & 2.21gpt TPM (0.62 gpt Pt, 1.24gpt Pd, & 0.35gpt Au). Surface trenching in Oct 2019 uncovered a zone of disseminated sulfide mineralization extending over >5m at surface. A 1.22m channel sample collected immediately before the onset of snow yielded 0.18% Ni, 0.85% Cu, and 1.94 gpt TPM (0.5 gpt Pt, 1.07 gpt Pd, & 0.37 gpt Au). This zone appears to connect with the melagabbro of the Eastern Zone where the blebby mineralization in the trench resembles that found at depth in the resource envelope. Further work is planned in the spring of 2020 as soon as the area is free of snow.
A further >5m long zone of mineralized gabbro which has uncertain relationship to Bird’s Bane may be within the footwall megabbrecia. Grab samples confirm the presence of anomalous Cu (0.2-0.4%) and TPM (0.16-0.48gpt).

The Bird’s Bane mineralization and associated trench samples provide important evidence that the footwall of the Shakespeare Intrusion is very prospective for the discovery of new zones of magmatic sulfide mineralization. Re- interpretation of data from the footwall of the Deposit shows strong evidence for the development of mineralization beneath the previously recognized intrusion, not only at surface, but in drill cores that penetrate into the footwall beneath the west and east mineral zones. The possibility of a significant body of mafic rock with mineralization in the footwall is supported by lithogeochemical data which indicate that the gabbros from the footwall of the Shakespeare Intrusion are unusually mafic and Cr-rich which is a feature of the deposit. Immediately to the south, interpretation of a regional airborne gravity data has identified an anomaly which is likely due to dense mafic rocks that are not mapped at surface.
The work at Brid’s Bane offers potential to grow the scale of mineralization towards surface in the east deposit, and also develop new shallow targets in the footwall. The potential for higher grade mineralization at depth in association with the gravity feature will be evaluated with surface electromagnetic survey work in 2020.
Peter Lightfoot, Vice-President of Exploration at Magna Mining Corporation stated: “The new data gathered from the footwall of the Shakespeare Deposit encourage careful exploration beneath the western and eastern Deposits. The elevated Ni, Cu, Co and precious metal tenors of the sulfides (i.e. metal abundances in 100% sulfide) require only a small increase in the amount of sulfide in the rock to generate significant grades that can impact the mine development plan”.
