Trillium Gold Mines Inc. provided results of extensive compilation of historical data and core sampling activities in the second half of 2022 over its approximate 55,000 hectare Confederation Belt project in Red Lake, Ontario. The project encompasses one of the largest contiguous land positions ever assembled along the same geological trends as the Red Lake Operations [Evolution Mining] and the LP Fault Zone of the `Dixie' discovery [Kinross Gold] in this world-class mining jurisdiction predominantly known for its VMS base metal mineralization. Trillium's program of re-logging historical core commenced in mid-2022 and continued until just prior to year end with over 10,000 metres of equivalent drilling completed.

Selection of the holes was based upon several gold related criteria, chiefly but not limited to, their proximity to high-potential structures, position on-trend of known gold mineralization and proximity to gold showings in historical or field sampling by Trillium. Trillium's geologists found that very little of the core had been sampled previously, with the limited sampling focused mainly on massive sulphides or EM conductors. Over 3,400 samples have been collected from the historical core - both from logged holes and grab sampled from old core caches that, despite being weathered and degraded, were identifiable as to drill hole numbering.

Approximately 20% of these remain pending. All the information gleaned from this comprehensive exercise, whether assay, lithology revisions, gold-associated alteration or unlogged veining, has been valuable in identifying priority target areas for either immediate drilling or focused enhancement through follow-up field work. In addition, the Company received seven (7) Early Exploration Permits that it had applied for beginning in April which will allow flexibility in drilling locations and timing throughout the Confederation Belt land package.

Shows the significant gold enhancement throughout Trillium's land package that has been unlocked through the 2021 and 2022 exploration work. This was derived through research and digitization of gold information from historical drill logs and assessment reports, as well as data collected by Trillium geologists during field programs. Working through more than 250 potential gold targets, the Trillium team is finalizing an initial drill program to test the best of these in an up-coming drilling program. During their work in 2022, Trillium's geologists recognized the significant potential for critical minerals throughout the property.

Both on and immediately adjacent to the property, occurrences of molybdenum, nickel and potentially cobalt have been identified. Lithium may also potentially be found both along the far eastern margins of the property and on the Karas Lake trend where the Confederation greenstones intrude southwesterly into the English River sub-province. The only NI43-101 level resource in the area (Pegasus Resources' Arrow Zone ­ see Tribute Minerals Technical Report on Garnet Lake Property, 2007) also indicates significant indium and gallium in the drill results.

Given that these metals are associated with copper and zinc mineralization, the large number of known Cu/Zn showings and occurrences throughout the Confederation property will need to be properly assessed for critical minerals. All these remain untested and will be a priority focus of the upcoming field season. To knowledge, little to no analysis was performed for these critical mineral-associated elements in the historical work.
