Trillium Gold Provides Update on Newman Todd and Gold Centre Projects

NEWS RELEASE

Trillium Gold Provides Update on Newman Todd and Gold

Centre Projects

Vancouver, BC, Canada – August 11, 202 2 – Trillium Gold Mines Inc. (TSXV:TGM ,

OTCQX:TGLDF, FRA:0702) (“Trillium Gold” or the “Company”) is pleased to provide an update on

the Company’s first half 2022 exploration and drilling activities at its two projects in Red Lake,

Ontario. These projects offer significant exposure to gold mineralization in a world-class mining

jurisdiction.

The on-going time delay between drilling and receipt of assays continues to be a significant hurdle

for Trillium Gold and many others in the advancement of informed targeted drilling. As a result, the

Company believes it prudent to suspend drilling at its Newman Todd and Gold Centre projects to

allow for all pending results to be received and compiled. Once the entirety of assay results ha s

been received and reviewed, subsequent drilling may resume on targets using up -to-date

information. In the meantime, the focus of active exploration activities is bein g directed at the

Company’s Confederation belt projects where re -logging of historic drill core presents compelling

prospects as Early Exploration permits are awaiting receipt. (See news release date d August 9,

2022.)

Newman Todd Complex – advancing open-pit scenario

Since January 2022, a total of 17 drillholes, for 7,665 metres, have been drilled at the Newman

Todd Complex. Currently over 2,100 assay results remain pending. (See Figure 1 for all holes

drilled on the Newman Todd Complex from January to June 2022).

Drilling at the 100% -owned Newman Todd-Rivard properties located some 26 km from Evolution

Mining’s Red Lake Operations, continues to validate the team’s interpretation that gold deposition

at the NT Zone is correlated with east-west structural corridors, and that several other structures

displaying significant widths of mineralization can be found by stepping out of the Main Zone. The

project has yet to be meaningfully drill ed beyond 400 metres from surface and continues to

demonstrate merit as a viable open-pit scenario with further informed drilling.

Surface channel sampling and mapping on the Rivard Property area continued into early summer

2022, although all 146 sample results remain pending. Alteration and wide -spread gold

mineralization occur s extensively within structurally and chemically favo urable rocks on the

property. Historically, the Rivard Property is known to contain both visible gold in narrow high-grade

veins, as well as in broader zones of lower grade gold mineralization ranging from <1 g/t Au to over

560 g/t Au (see news release dated June 29, 2021 – New Discovery Hole at Rivard Confirms High-

Grade Visible Gold with 129.79 g/t over 1.30 metres).

Previous channel sampling results have shown that the significant gold values are not confined to

small areas within the veins but occur over significant strike lengths , and at considerable grades,

along the veins following structural plunges.

Understanding the controls and geometry of the high -grade mineralization seen on surface and

intersected in drilling on Rivard is important to the expansion of the overall system. Trillium’s

geological team has shown that this vein system is influenced by the east-west structures evident

in the NT Zone which will increase the success in delineating high-grade shoots that can favourably

impact Newman Todd’s economic prospects.

Gold Centre Property – targeting Red Lake mine stratigraphy

Since January 2022, a total of 4,950 metres in five holes were drilled, including GC22 -10 which

contained eight wedges. Over 450 assay results remain pending.

The Gold Centre property encompass es 253 hectares and is located immediately adjacent to

Evolution Mining’s Red Lake Operation, which to date has produced more than 25 million ounces

of gold at an average grade of 15 grams per tonne. Trillium’s 2021 drill program focused on the

north end of the property, with eight drill holes targeting Red Lake Mine stratigraphy above 900

metres of vertical depth. The winter-spring 2022 program aimed at testing deeper in the stratigraphy

while targeting the modeled up-plunge projection of the deep mineralization at the Red Lake

Operation, at around 1,400 metres depth.

Proving the continuity with the Red Lake Operations is, first and foremost, hinged on identifying the

Balmer host rocks at depth which Trillium has achieved from the start . The results to date have

been positive with good evidence that correlates with the high-grade gold mineralization believed

to be present on the property. The Balmer assemblage rocks are typical of those observed at the

Red Lake Mine, both in lithology and veining and are generally moderately to strongly foliated,

veined moderate-heavily by quartz-calcite (±carbonate).

All the key components that are ubiquitous to the gold mineralization immediately to the west have

been observed and the alteration is seen generally increasing westward over the property, being

largely confined to the Huston -Balmer assemblage contact in the east to increasing intensity

westward. Biotite alteration, intimately associated with gold mineralization at the Red Lake Mine,

is more abundant towards the west side of the Gold Centre Property and is brown to reddish-brown

in colour.

Trillium Gold’s expansion strategy across Red Lake’s major crustal faults

Over the last few months, the Company has made significant strides in consolidating its strategic

land position across the major fault structures attributed to Red Lake’s reputation as a world -

class mining jurisdiction . Along the Confederation and Birch -Uchi greenstone belts , the

completion of a series of acquisitions directly and through option agreements , has brought

Trillium’s land assemblage to 60,080 hectares. The Eastern Vision projects alone, which closed

in late June, created a contiguous land package over more than 100 km of favourable structures

on trend with Kinross Gold’s Dixie Project and Evolution Mining’s Red Lake Operation.

Most recently, the Wenasaga property located 35 km to the west of and on strike with Kinross

Gold’s Dixie Project, and the Panama Lake properties aggregating over 11,500 hectares and 80

km from Dixie, have extended Trillium Gold’s dominant contiguous foothold in the belt where

major structures that transect the propert ies appear to be splays from, or are the eastern

extension of the LP Fault structure. Multiple gold and VMS -style mineralization occurrences

have been identified on the se properties and field program s have already been designed to

expand on and evaluate the lateral continuity of these mineralized trends.

Earlier in April, the Uchi Gold and Satterly Lake Gold agreements extended Trillium’s holdings

to the northeast in proximity to First Mining’s Springpole Project.

All these acquisitions present Trillium with an unprecedented opportunity to explore for further

LP Fault analogues, other Red Lake -style gold mineralization , and critical minerals along a

structure that is many times larger, and equally as prospective as the Great Bear Project.

All Newman Todd Complex 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. All Gold Centre drilling was supervised by Richard Kowalski and

Samuel Lewis, PGeo.

Core samples from these programs were cut in half, using a diamond cutting saw, and half cores

were sent for analysis to Activation Laboratories Ltd. in Dryden , ON, an accredited mineral

analysis laborator y. All sam ples were analy zed for gold using standard Fire Assay -AA

techniques. Samples returning over 10.0 g/t gold were analyzed utilizing standard Fire Assay -

Gravimetric methods. Any 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.

References to visible gold (VG) are factual observations and should not be construed as

quantifiable grade.

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.
