Aroland First Nation, Animbiiggo Zaagi'gan Anishinaabek and Ginoogaming First Nation Enters into Exploration Agreement with Tombill Mines

The Three First Nations mentioned hereto are the limited partners of Minodahmun Development Limited Partnership ("MDLP"). Minodahmun (meaning "clear path" in Ojibway) is a 100% community owned partnership between the Three First Nations. MDLP's goal is to ensure that benefits from sustainable mining projects are shared equitably with the Three First Nations and provide opportunities for community members.

The Exploration Agreement with the above Three First Nations contains measures to accommodate and address concerns including impacts to Indigenous rights, cultural values, and the environment prior to exploration activities. The Exploration Agreement will prevent and minimize impacts on the Three First Nations through a variety of mitigation measures and offsetting benefits. Tombill recognizes the significance of the affected lands to the Three First Nations. In return the Three First Nations have provided their consent for Tombill's Exploration activities.

Adam Horne, CEO, commented: "We are pleased to announce a mutually respectful and consent-based relationship with the Three First Nations and look forward to working with them over the years to come. Tombill are committed to developing positive relationships, which recognizes the need for each Party in the Agreement to mutually benefit and co-exist. We are happy to fully engage in the collaboration to ensure smooth operations as we advance our mineral claims in and around Geraldaton."

Joe Donio, President of MDLP, commented: "This is a major milestone for the Three First Nations and Tombill. It demonstrates the importance of seeking free, prior, and informed consent for exploration projects. The Exploration Agreement provides environmental oversight, regular consultation, employment, and contracting opportunities for the Three First Nations among other provisions. We look forward to working collaboratively with Tombill over the coming years as Greenstone develops into Canada's newest mining hub."

About Tombill

Founded 1935, by Newmont Mining and prospectors' 'Tom' and 'Bill' Johnson, Tombill owns 4 claim groups, of which 3 claim groups are situated in the Geraldton gold district of north-central Ontario (~225 km's NE of Thunder Bay). Geraldton houses superior installed infrastructure. Holdings comprise 74 royalty-free mining claims (60 fully owned patented claims, 5 leases, 9 mineral rights only). Of these, the 51-patented claim Main Group is in the centre of the Geraldton Gold Camp and straddles the Trans-Canada Highway; the 5-claim Ellis Group lies 4 km's south of the town of Geraldton; and the original Tombill Mine group of 6-patented claims sits 10 km's west-southwest of Geraldton. The Tombill gold mine, which produced 68,737 high-grade ounces between 1938 and 1942 is in the southeast corner of the claim group. The Talmora Longlac mine, in the Main Group was built in 1941, but saw only minor production before closing in 1942 (1,406 ounces gold). The Main Group borders on the property of the under-construction Greenstone Gold Mine, which will be one of Canada's largest gold mines with production aimed for 2024.

In 2021, Tombill completed two drilling campaigns:

• Tested the deep, western continuation of the F-Zone orebody that had been exploited to our east by Greenstone Gold Mine's past-producing MacLeod-Cockshutt and Mosher underground mines, and successful recent drill programs right up to our boarder. Drill-hole intersections of the F Zone by holes T21-5A and T21-5E, with intercepts of 6.23 grams/tonne Au over 13.3 meters, and 5.29 grams/tonne Au over 8.0 meters, respectively. (PR's: June 17, Sept 20, 2021)

• 3-hole program testing for low-grade mineralization around the former Talmora mine. Best intercept was TAL21-002, with 1.65 grams/tonne Au over 11.5 meters from 154.5 meters down-hole. (PR: November 15, 2021)
