Trillium Gold Mines Inc. (Trillium Gold or the Company) provided an update from the lithogeochemistry, structural and stratigraphic studies over its approximate 570 sq km Confederation Belt project in Red Lake, Ontario. The project encompasses one of the largest contiguous land positions ever assembled in the Red Lake mining district, bound by the same geological trends that have defined the Red Lake Mining District as a world-class mining jurisdiction. The results from the Company's field work strongly suggest structural, stratigraphic, and litho- geochemical similarities along or adjacent to the eastern extensions of both the LP Fault, associated with Kinross Gold's Great Bear project, and the Cochenour-Gullrock Fault, associated with Evolution Mining's Red Lake Mine.

To the southeast on the Panama Lake property, trace element lithogeochemistry has identified strong similarities between the metavolcanic rocks from the Panama Zone with the Felsic Domain of the Great Bear project. The mafic volcanic rocks also show a strong similarity to high-Fe basaltic rocks from the Great Bear project's Mafic Domain. Primitive-mantle normalized trace element plots illustrate similarities between the Great Bear project and the Panama Lake property, suggesting high potential for gold discovery.

Trillium's re-logging of historical core of the Panama Zone from mid-2022 through to early 2023 shows remarkable textural similarities to core seen at the Great Bear project. The Panama Zone historical gold mineralization (e.g., 1.58 g/t Au over 7.6 m, and 13.33 g/t Au grab sample) occurs within similar rock types and stratigraphic horizon along the Panama Fault North Trend, a potential eastern extension or splay of the LP Fault. An airborne electromagnetic lineament coincident with the gold-bearing Panama Zone shows the Panama Zone and Panama Fault North Trend continuing to the northeast where recently completed enzyme leach soil surveys identified multiple overlapping anomalies for arsenic, nickel, zinc, silver, and chromium.

Arsenic in soil is a strong pathfinder candidate for gold mineralization based on historical geochemistry work performed on drill holes completed by Benton Resources in 2019 and a baseline soil line completed over the Panama Zone by Trillium in 2022. In the central part of the Confederation Belt project along the Cochenour-Gullrock (Red Lake Mine) Trend, trace element analyses in mafic volcanics and associated rocks from historical drill core have identified similarities between Red Lake-associated Balmer assemblage volcanic rocks. This newly discovered spatial relationship of Balmer affinity rocks adjacent to Confederation assemblage rocks suggests that the Cochenour-Gullrock Trend and associated unconformity continues from Red Lake across the northern portion of Trillium's Confederation Belt project.

Gold results of up to 0.99 g/t in recently analyzed historical core, and up to 1.56 g/t from historic assays, occur proximal to the Cochenour-Gullrock Trend and to the unconformity over several kilometres as reported in Trillium's news release of February 7, 2023.
