• NT22-211 intersects 40.56 g/t Au over 4.18 meters including 136.0 g/t Au over 1.08 meters;

VANCOUVER, British Columbia, Sept. 26, 2022 (GLOBE NEWSWIRE) — Trillium Gold Mines Inc. (TSXV:TGM, OTCQX:TGLDF, FRA:0702) (“Trillium Gold” or the “Company”) is pleased to provide a update on the latest results from the Company’s exploration and drilling activities in the first half of 2022 at the Newman Todd complex in Red Lake, Ontario.

The two drill holes (NT22-211 and 212) were designed to test the deeper, southerly trending extensions of mineralization associated with the Main Zone Fault approximately 100 meters to 250 meters below all drill holes. previous ones, located in a space in the drilled part. of the NT area. Both holes significantly increase the depth of the mineralization to almost 600 meters in this area. Figures 1 and 2 show these boreholes in plan and in longitudinal section.

Russell Starr, President and CEO of Trillium Gold, said, “These exceptional results indicate the potential for a sizeable increase in Newman Todd’s resources and strongly support our thesis regarding the structural controls that drive high-grade occurrences in NT area. These occurrences trend southeast of the NT Zone in the hangingwall sequence. Historically, Newman Todd has not been drilled significantly below 400 meters depth, and we now see real high-grade potential with the east-west structures holding the key to discovering new gold mineralization outside the known NT zone.

Gold mineralization was also intersected in the hangingwall rock units beyond the contact of the NT Zone and Main Zone Fault, with visible gold¹ (VG) detected a 2 mm quartz vein at 614.2 m from NT22-212 (549 g/t Au over 0.3 m), in a section of banded chert formation and iron formation of the sequence of roof. This hangingwall gold showing, within the wider significant interval of 8.75 g/t Au over 20.4 metres, along with other historic hangingwall intersections indicate that mineralization gold bearing associated with the NT Zone and associated east-west shears (p. ), continues in the hangingwall rock units to the southeast of the NT Zone, thereby expanding the possible drill target areas and the envelope potential mining pit in the project area. Historical drilling in this area has generally stopped short of intersecting this mineralization when drilled from the toe wall. Very little reverse drilling has been done overall, leaving this mineralization undiscovered.

William Paterson, Vice President of Exploration for Trillium Gold, 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 high-grade Rivard veins. elevated and east-west structures. Our most significant previously reported high grade intersections – 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 successfully apply this established theory at depth, which remains completely open .

Since January 2022, a total of 17 drill holes over 7,665 meters have been drilled at the Newman Todd complex. The remaining analytical results will be published once all results have been interpreted and the larger structural framework can be quantified.

All drilling was supervised by Paul Barc, PGeo. The drilling was carried out by Rodren Drilling Ltd. of West St. Paul, Manitoba. Drill cores were logged and sampled in a secure on-site core drill. Core samples from the program were cut in half using a diamond saw, and the half cores were sent for analysis to Activation Laboratories Ltd. in Dryden, Ontario, an accredited mineral analysis laboratory. All samples were assayed for gold using standard Fire Assay-AA techniques. Samples returning greater than 10.0 g/t Au were assayed using standard fire assay and gravimetric methods. All samples with results greater than one ounce per tonne of gold were also assayed with a standard 1 kg metal screen fire assay unless there was insufficient remaining sample material. Reference standards, blanks and certified gold duplicates are regularly inserted into the sample stream, as part of Trillium Gold’s Quality Control/Quality Assurance (QAQC) program to monitor accuracy and precision . No QAQC issues were noted with the results reported here. All reported drill intersections are downhole core lengths, which do not necessarily represent actual widths.
