Update On Drill Program At Rivard Property Southwest Of Newman Todd

VANCOUVER - Trillium Gold Mines Inc. reported an update on the drill program underway on the 100%-owned Rivard property, located at the southwest portion of the Newman Todd project. The Newman Todd Zone (NT Zone) is currently a 2.2 km long and up to 200 meter wide structural target which is situated in the Red Lake Gold Camp. Seven holes have so far been completed for 3,484 meters since the start of the drilling in early 2021.

The drilling on the Rivard property is expected to expand the understanding of the continuity of the high-grade veining both along strike and at depth on Rivard and into the Newman Todd Structure, where previous shallow trenching revealed spectacular visible gold (VG) and the structural influence on higher-grade intersections in the NT Zone.

Three holes tested the southwest extension of the NT Zone while four holes began testing the lateral and depth continuity of the high-grade veining as seen on surface and in the historical trenches. With the early onset of thawing spring temperatures, combined with a backlog in analyses, results from only two holes have been received to date.

Holes RV21-25 to RV21-27 were drilled in the southeast corner of the Rivard property to test the southwest extents of the NT Zone where it crosses through the corner of the Rivard lease. Breccias of the NT Zone were intersected in both holes with the desired sulphidized and magnetite-bearing sub-units prevalent.

RV21-25 was drilled at the far southwestern extension of the NT Zone but did not hit the NT Zone breccias as historically mapped on surface 200-300m to the northeast. The interpretation is that the NT Zone does not continue to depth in this area or there is a structural offset to the south. The rocks encountered in the hole were mainly massive to weakly foliated felsic tuffs with minor carbonate veining up to 20cm. The best assay was 0.45m @ 2.75 g/t Au.

Hole RV21-26 collared in NT Zone breccia and drilled through 137.8 meters of this with a second NT Zone horizon encountered from 342.6 to 484.7 meters. The upper NT Zone unit was a previously unknown horizon.

Hole RV21-27 was located 50 meters back to obtain a full intersection of this new northern band of the NT Zone. It intersected this horizon from 160.5 meters to 435.4 meters. The southern band was intersected from 459.3 to 481.4 meters. Both NT Zone horizons contained varying sub-units of silicified, sulphidized and magnetite-bearing breccias. Closer inspection of the bottom of RV21-27 revealed sulphidized and brecciated sections in the felsic tuffs warranting continuation of this hole at a later date.

Four holes (RV21-24, RV21-28 to RV21-30) have been completed, testing the orientation and continuity of the high-grade veining in the central portion of the Rivard property. All the holes were designed to test under and along strike of the historical trenching. Lithology units encountered comprised mainly of quartz- and quartz-feldspar porphyry with varying amounts of altered ultramafic rocks. Numerous occurrences of VG have been noted in the logging with specks and blebs of VG mineralization contained in 0.5 to 5cm quartz veins intruding all lithological units.

Bill Paterson, Head of Exploration, said, "Our first few holes on the Rivard property testing both the southwest extension of the NT Zone and under the historical trenches with the high-grade veining have already been a success. Even with most assays yet to be received, we have seen VG in a number of quartz veins associated with the trenches and have intersected a possible parallel or structural enhancement to the NT Zone in the southwest.”

Prior drilling on the NT Zone from 2013 and earlier had mostly focused on testing the Zone by targeting the footwall with drilling toward the southeast, now known to be sub-parallel to gold mineralized veining and structures, potentially missing high-grade intersections or undercutting much of the targeted zone. Newman Todd is a highly prospective target with 41% of the 165 historic drill holes having intervals of greater than 20 g/t gold over various lengths. In addition, nearly all drilling has been conducted to depths of less than 400 meters.
