[{"type":"text","content":"Magna Terra Intersects Broad Zones of Alteration at Rattling Brook, Great Northern Project, NewfoundlandTORONTO, ON / ACCESSWIRE / November 22, 2021 / Magna Terra Minerals Inc. (the \"Company\" or \"Magna Terra\") (TSX-V:MTT) is pleased to announce that it has intersected broad zones (up to 95 metres true thickness) of sulfide (pyrite (‘Py\") and arsenopyrite (\"Aspy\")) mineralization and alteration within and adjacent to the Apsy Zone of the Rattling Brook Deposit (the \"Deposit\") on its 100% owned Great Northern Project (\"Great Northern\"), located in western Newfoundland. The Apsy Zone and adjacent Apsy Feeder Zone were tested as part of a recently completed 10 drill hole (JA-21-124 to 133), 1,253 metre diamond drilling program designed to better define and expand upon the existing mineral resource at the Deposit (the \"Drill Program\"). Sulfide mineralization and intense alteration of host granitic rocks are intimately associated with gold mineralization at the Deposit (Exhibit A and B) and have been intersected 150 metres northwest of the Deposit within a fault referred to as the Apsy Feeder Zone.Assays are pending for all 950 drill core samples submitted for analysis, however, intersecting sulfide mineralization and associated alteration compare favourably to gold-bearing intervals from drilling within the mineral resource. Based on these key indicators the drill program was upsized to 1,250 metres and has successfully demonstrated the discovery potential at Great Northern where the Deposit remains open along strike and along fault systems like the Apsy Feeder Zone (Exhibit C).Key drilling sulfide and alteration intersections include:1% Py and Aspy (up to 10% locally) over 62.3 metres (3.1 to 65.4 metres; estimated true thickness (\"TT\") 65 metres) in diamond drill hole JA-21-124;1 to 2% Py and Aspy (up to 8% locally) over 191.5 metres (1.5 to 193.0 metres; TT 50 metres) in diamond drill hole JA-21-129;1 to 2% Py and Aspy (up to 10% over 1 metre) over 188.5 metres (1.5 to 190 metres; TT 50 metres) in diamond drill hole JA-21-131; and1% Py and Aspy (up to 5% in local zones) over 105.5 metres (1.5 to 107 metres; TT 95 metres) in diamond drill hole JA-21-133.Previous (1986 to 2007) select drill intercepts (core length) that partly define the Apsy Zone adjacent to the area of the Drill Program include:1.77 g/t grams...
