Turmalina Awarded Drill Permit for Chanape Project

• Preparations underway for drilling program targeting multiple high-grade Cu-Au-Ag breccia pipes.
• Breccias clustered around mineralised intrusions that have the potential to host large-tonnage Cu-Mo systems.

VANCOUVER, British Columbia, May 24, 2022 (GLOBE NEWSWIRE) -- Turmalina Metals Corp. (“Turmalina”, or the “Company”; TBX-TSXV, TBXXF-OTCQX) is pleased to announce that Company’s Peruvian subsidiary Aurora Copper Perú S.A.C. has received its Ficha Técnica Ambiental (‘FTA’) permit for the Chanape Project (“Chanape” or the “Project”), located in Lima Province, Peru. The FTA permit provides approval for drilling and is granted by Peru’s Ministry of Energy and Mines. Together with a recent agreement with the local community of Checa, the granting of the FTA is a major milestone for any exploration project in Peru.

Preparations for drilling at the Project are well underway, with drill pads already planned and final quotations received for camp facilities. Drilling contractors have visited site with the final drilling contractor to be selected in the next few weeks. The Company has applied for a water permit, which is the final permit required prior for drilling, that is expected to be granted in June.

The Chanape project contains several strongly mineralised tourmaline breccia pipes that are clustered around a large copper-molybdenum mineralised intrusion. Drilling by the previous owners of the Project intersected broad zones of high-grade Cu-Au-Ag breccia mineralisation on the margins of the intrusions that were not followed up. These intersections include:

• Clint Breccia: 71m at 1.92 % Cu, 0.81 g/t Au & 41 g/t Ag (sulphide, CHDDH013)
• Clint Breccia: 55m @ 2.25 % Cu, 0.57 g/t Au & 42 g/t Ag (sulphide, CHDDH012)
• Breccia 8: 108m @ 1.98 g/t Au & 41 g/t Ag (Cu-leached oxide zone, CHDDH001)
• Breccia 8: 64m @ 0.87 g/t Au and 25 g/t Ag (Cu-leached oxide zone, CHDDH012)
• Breccia 11: 150m at 0.47 g/t Au & 4 g/t Ag (Cu-leached oxide zone, CHDDH002)
• Breccia 11: 62m at 0.61 g/t Au & 5 g/t Ag (Cu-leached oxide zone, CHDDH003).

High-grade mineralisation in all these breccias remains open along strike and at depth. Two historic holes drilled into the ~1.5 km by 0.75 km wide mineralised intrusive body (the “Chanape Igneous Complex”) in the centre of the Chanape breccia cluster intersected broad zones of moderate copper-molybdenum mineralisation with grades typical of primary (‘hypogene’) porphyry mineralisation in Peru (i.e. Chanape Porphyry: 284m @ 0.32% Cu and 83 ppm Mo; CHDDH011). With only limited drilling into this intrusive complex there remains strong potential for similar mineralised intrusions.
