Trillium Gold Reports 8.75 g/t Au over 20.4 metres including 549.0 g/t Au over 0.3 metres and Discovers New Deep Mineralization Outside Newman Todd Zone

Vancouver, BC, Canada – September 26, 2022 – Trillium Gold Mines Inc. (TSXV:TGM, OTCQX:TGLDF, FRA:0702) (“Trillium Gold” or the “Company” - https://www.commodity-tv.com/ondemand/companies/profil/trillium-gold-mines-inc/) is pleased to provide an update on the latest results from the Company’s first half 2022 exploration and drilling activities at the Newman Todd Complex in Red Lake, Ontario.

The two drill holes (NT22-211 and 212) were designed to test the southward-trending and deeper extensions of the Main Zone Fault-associated mineralization about 100 metres to 250 metres below all previous drill holes, situated in a gap in the drilled portion of the NT Zone. Both holes considerably expand the depth of mineralization down to almost 600 metres in this area. Figures 1 and 2 show these drill holes in plan and long section.

Russell Starr, President & CEO of Trillium Gold stated, “These exceptional results indicate the potential for an appreciable increase in the Newman Todd resource, and strongly support our thesis regarding the structural controls that determine high-grade occurrences within the NT Zone. These occurrences trend southeast of the NT Zone into the hanging wall sequence. Historically, Newman Todd has not been meaningfully drilled below 400 metres depth, and we are now seeing real high-grade potential with the east-west structures holding the key to discovering new gold mineralization outside of the known NT Zone.”

Gold mineralization was also intersected in the hanging wall rock units past the NT Zone contact and Main Zone Fault, with visible gold¹ (VG) logged in a 2mm quartz vein at 614.2m of NT22-212 (549 g/t Au over 0.3m), within a banded chert and iron formation section of the hanging wall sequence. This hanging wall gold occurrence, within the broader significant interval of 8.75 g/t Au over 20.4 metres, as well as other historical hanging wall intercepts indicate that gold mineralization associated with the NT Zone and associated east-west shears (eg. Main Zone Fault), continues into the hanging wall rock units southeast of the NT zone, thus expanding the possible drill target areas and potential mining pit shell within the project area. The historical drilling in this region generally stopped prior to intersecting this mineralization when drilled from the foot wall. Very little drilling in the opposite direction was carried out overall, leaving this mineralization undiscovered.

William Paterson, Trillium Gold’s Vice President of Exploration added, “These results are the most significant received to date at this depth at Newman Todd and signal the potential for additional resources associated with intersections between the bonanza-grade Rivard veining and east-west structures. Our more meaningful high-grade intersections previously reported - holes NT20-169 [7.05m at 15.41 g/t Au including 4.3m at 23.88 g/t Au and 1.12m at 69.85 g/t Au], and NT21-194 [9m at 19.73g/t Au including 1.55m at 102.16 g/t Au] on the Camp Fault, and now holes NT22-211 and -212 on the Main Zone Fault, have all occurred at these intersections and we believe we will be able to apply this established theory successfully at depth, which remains completely open.” [See Trillium Gold’s news releases at www.trilliumgold.com or its filings on www.sedar.com]
