VANCOUVER, BC

June 29, 2021

/CNW/ -

Trillium Gold Mines Inc.

(TSXV:TGM) (OTCQX:TGLDF) (FRA:0702) ("Trillium Gold" or the "Company")

reports the results from three drillholes at the Rivard Property portion of the Newman Todd Project in

Red Lake, Ontario

. The Rivard Property consists of

one lease of six contiguous mineral claims encompassing 90 hectares, 26 km from Evolution Mining's Red Lake Operations. Visible bonanza-grade gold is

observed in quartz veins in drill holes and in outcrops/trenches across the property. Alteration and wide-spread gold mineralization occur extensively within

structurally and chemically favorable rocks. Historically, the Rivard Property contains both visible gold in narrow high-grade veins as well as in broader zones

of lower grade gold mineralization.

These are the first three holes (RV21-28 to RV21-30), in a series of drill holes targeting the Rivard high-grade gold veining, and are drilled parallel to each

other perpendicular to the strike of the gold bearing vein system (see Figure 2). The visible gold seen in RV21-29 (Figure 1) is the first bonanza intersection

received from the drilling to date.

"Drilling at the Rivard Property has continued to present us with some spectacular visible gold. Previous drilling only tested immediately below the existing

trenches where the veins and occurrences of VG was known. Our drilling has pushed the known gold in the veins to approximately two hundred metres

below the surface and each hole has yielded numerous occurrences of VG. As we add more holes to the project, we expect to be able to gain appreciable

proficiency to predict targets for higher grade mineralization within the vein system" commented

Bill Paterson

, head of exploration.

Russell Starr

, CEO of Trillium Gold commented, "This is a major new discovery for Trillium. Historically the Rivard family had produced enough gold off the

Rivard property to survive for three decades. While we knew there was gold in quartz veins, to encounter such high grade in our first drill program is an

exceptional outcome for both our technical team led by Bill as well as for our shareholders. This intersection further substantiates the tremendous potential

for Newman Todd to become the next mining operation in

Red Lake

running NE/SW on the Newman Todd property. (CNW Group/Trillium Gold Mines Inc.)

Interpretation of the veining and VG occurrences in the core is establishing that there is a series of corridors showing an increased frequency of gold

veining. These are oriented in the previously identified NW/SE trend. Subsequent interpretation of the assay results indicates that in reality, any assay over 1

g/t signifies that a corridor has been intersected.

Further drilling will be completed to test the limits as well as the horizontal and vertical extents of these corridors and determine their interaction with the NT

Zone to the southeast. There is also the possibility that there are other VG-bearing vein corridors further northeast on the property, to be determined with

further drilling.

RV21-28 targeted the down dip projection of gold veining on surface seen in the Long Pit and Sadler Pit trends. The hole primarily intersected narrow quartz

and quartz-feldspar porphyry sections, wider sections of altered ultramafic rocks and a few sections of mafic dykes. Visible gold was intersected at

20.42m

downhole and several specks of visible gold were seen in the section from

79.70m

downhole. Highlights from RV21-28 are listed below. All

significant assay intercepts are shown in Figure 3 and Table 1.

RV21-29 was collared back and

east of RV21-28 to intersect an additional vein trend east of the Long Pit trend, targeting under the south end of the

Long Pit trend. The hole was designed to also drill under the Sadler Pit trend

160m

to the west. The hole intersected a series of quartz and quartz feldspar

porphyry sections, alternating with six sections of altered ultramafic at the end of the hole. Visible gold was seen at

The Red Lake Camp is famously known for high grade gold mineralization at depth, with Evolution Mining's Red Lake Gold Mine currently reaching depths of

several thousand feet. Trillium continues to test various drill orientations in order to develop a comprehensive understanding of the mineralization and

structural controls and test the depth potential of the Newman

Todd Zone

and the Rivard Property vein system.

All drilling was supervised by

Paul Barc

, PGeo. The drilling was conducted by Rodren Drilling Ltd., of

West St. Paul, Manitoba

. Drill core was logged and

sampled in a secure core facility on site. Core samples from the program were cut in half, using a diamond cutting saw, and half cores were sent for

analysis to the SGS Laboratories in

Red Lake, ON

, and

Burnaby, BC

and Activation Laboratories Ltd. in

Dryden

and

Thunder Bay, ON

, all accredited

mineral analysis laboratories. All samples were analysed for gold using standard Fire Assay-AA techniques. Samples returning over 10.0 g/t gold were

analyzed utilizing standard Fire Assay-Gravimetric methods. Selected samples with results greater than one ounce per ton gold were also analyzed with a

standard 1 kg metallic screen fire assay. Certified gold reference standards, blanks and duplicates are routinely inserted into the sample stream, as part of

Trillium Gold's quality control/quality assurance program (QAQC) to monitor accuracy and precision. No QAQC issues were noted with the results reported

herein. All drill intercepts reported are down-hole core lengths, which does not necessarily represent true widths.

The technical information presented in this news release has been reviewed and approved by William Paterson QP, PGeo, VP of Exploration of Trillium

Gold Mines., as defined by NI 43-101.
