Tombill Mines to Kick-Off Phase 2A Drilling Program on Their Claims in Geraldton Gold Camp

Exploration Programs

Tombill Mines to Kick-Off Phase 2A Drilling

Program on Their Claims in Geraldton Gold

Camp

Toronto, Ontario and Geraldton, Ontario--(Newsfile Corp. - March 24, 2022) - Tombill Mines Limited

(TSXV: TBLL) (the "Company", "Tombill"), a gold exploration company which owns 4 properties,

including 2 past-producing mines, in the Geraldton gold mining district, north-central Ontario, Canada is

pleased to announce it will commence its Phase 2A Drilling Program in mid-April. Drilling company

Forage FTE Drilling ("FTE") has been contracted to complete approximately 3,000 meters of diamond

drilling that will probe multiple targets identified by the Company on two of its properties.

Key Aspects of the Planned 2A Program

Start mid-April

~3,000 meters drilling to test ~8 separate targets

Main Group-7 targets based on geological, historical, and airborne magnetometer data

Tombill Mine-1 target to be drilled on the 6-claim original past-producing property

Individual drill-holes between 275 to 350 meters in length

Initial results expected June 2022

Adam Horne, CEO, commented, "Our campaign is being directed by our experienced exploration team

with strong local understanding of the key controls on the Geraldton district's gold deposits. This

knowledge has been applied in the definition of the drill targets that we will be testing.

Our Main Group claims lie at the centre of the Geraldton district, a globally important gold producer, with

a little more that 3 million ounces of gold recovered from 10 mines (2 of which are Tombill's),

intermittently extracted between 1935 and 1970, and where a major open pit mine is currently being

constructed approximately 3km's east of our boundary.

Our Phase 2A Drilling Program has been designed to probe for new gold zones that would complement

the deep-lying gold mineralization identified by our 2021 drilling campaign which was primarily focused

on testing the western extension of the F Zone orebody."

Ron Burk, Strategic Advisor and Head of Exploration and Geology, commented; "The drill targets

identified on the Main Group and Tombill Mine claim groups are defined on geological structures which

elsewhere in the Geraldton district have been shown to control the formation of gold ore bodies. Shear

zones along iron formations and shallowly plunging fold closures developed in the sedimentary

sequences intruded by felsic porphyry bodies are viewed as being high-potential targets. Moreover, the

areas of our planned drilling have seen very little previous work mainly because of a lack of bedrock

exposure due to water or muskeg cover."

Quinton Hennigh, Geologic/Technical Director of Crescat Capital, a strategic Tombill shareholder,

offered: "Tombill holds a very strategic land position right in the heart of the Geraldton gold camp, soon

to be the site of the newest large gold mine in Canada, Equinox's Greenstone Gold Mine. The

similarities between geological settings found on Tombill's land and at the Greenstone project are

striking. It has been a delight to work with Ron Burk and the rest of Tombill's exploration team in putting

together a comprehensive drill test of the highest ranking drill targets across this property. We are very

eager to soon see the results from this critical drilling program."

Geraldton Gold Camp

The Camp, comprising 10 past-producing mines, is approximately 15 km in length over a defined

corridor housing multiple shallow and deep gold zones along the Trans-Canada Highway from the most

easterly Hardrock mine, now the site of the Greenstone Gold Mine, to the most westerly Jellicoe Mine.

Tombill's patented claims (Main Group, including Talmora Longlac Mine) are virtually in the middle of this

corridor, and Tombill Mine claims lie to the west.

The current defined and demonstrated past-production,

reserves and resources of this district comprise:

Approximately 3.1 Moz gold intermittently extracted from 10 past-producing mines

(1)

Greenstone Gold Mines Project

(2)

Encompasses 4 former underground mines; ~2 Moz past-production

7.1 Moz Measured & Indicated Resources (inclusive of 5.3 Moz Proven & Probable

Reserves)

3.1Moz Inferred Resources

Open pit mine under construction; aims to pour gold in 2024

Greenstone's Kailey/Little Long Lac + Key Lake low-grade resources of ~0.7 Moz gold

(2)

To date, no gold resources have been attributed to 4 other past-producing mines in the district,

including the Magnet, Bankfield, Tombill and Talmora Longlac mines

About FTE

Founded 1987, Forage FTE Drilling specializes in a variety of drilling services in Canada, Africa, and

South America. Renowned for the quality of its work, FTE Drilling ensures an unmatched response time

in a safe and environmentally friendly workplace.

They have recently drilled in the Geraldton district.

About Tombill

Founded 1935, by Newmont Mining and prospectors' 'Tom' and 'Bill' Johnson, Tombill owns 4 claim

groups, of which 3 are situated in the Geraldton gold district of north-central Ontario (about 225 km NE of

Thunder Bay).

Geraldton offers optimal and 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 south of the town of Geraldton; and the original Tombill Mine

group of 6-patented claims sits 10 km west-southwest of Geraldton. The Tombill Gold Mine produced

68,737 high-grade gold oz between 1938 and 1942 is in the southeast corner of the claim group. The

Talmora Longlac Mine, within the Main Group, was built in 1941, but saw only minor production before

closing in 1942 (1,406 gold oz). 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 which and been shown by deep drilling to extend up to our eastern property boundary.

Drill-

hole intersections of the F-Zone were made by holes TB21-5A and TB21-5E, 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 Longlac mine.

Best

intercept was made by TAL21-002, with 1.65 grams/tonne Au over 11.5 meters from 154.5 meters

down-hole. (PR:

November 15, 2021)
