Company to Focus on Expanding Fenelon Gold System

Toronto, Ontario – September 14, 2020 – Wallbridge Mining Company Limited (TSX:WM) ("Wallbridge" or the "Company") today announced that it has entered into a non-binding term sheet (the "Term Sheet") with respect to a joint venture of its Detour East gold property ("Detour East" or the "Property") with Kirkland Lake Gold Ltd. (TSX:KL) ("Kirkland"). Under terms of this joint venture, Kirkland can earn a 75% interest in Detour East by making expenditures totalling $35 million on the Property, as described below.

"This Term Sheet, and ultimate joint venture agreement, is strategic for Wallbridge as it allows the Company to focus on fully-defining the size potential of our 100% owned Fenelon Gold property ("Fenelon") while at the same time advancing exploration on Detour East located at the far west end of the very large land position Wallbridge acquired through its acquisition of Balmoral Resources Ltd. ("Balmoral")," stated Marz Kord, President & CEO of Wallbridge. "The acquisition of Balmoral was primarily motivated by our belief that the Fenelon Gold system was larger than had been defined at that time, and that it extended onto Balmoral's ground immediately adjacent to our original Fenelon Gold property. This belief has now been confirmed by our initial drill results west and south of Fenelon (see press release dated September 8, 2020) and will be our immediate exploration focus.  In addition, numerous other high priority targets on other areas of the recently acquired Balmoral ground, including the area around the Martinière deposit, also deserve exploration which Wallbridge will evaluate over the coming months. Entering into a joint venture with Kirkland on the Detour East will allow us to focus on the Fenelon gold system, and will bring us a high-quality partner with excellent knowledge of the regional geology through its Detour Lake operations, located adjacent to Detour East."

Under the terms of the Term Sheet, Wallbridge will grant Kirkland the option to acquire up to an undivided 50% interest in the Property by funding phase 1 expenditures of $7.5 million over five (5) years (the "Phase 1 Expenditures") with a minimum commitment of $2.0 million in the first two years ($0.5 million by the first anniversary and $1.5 million by the second anniversary of entering into a definitive joint venture agreement) (the "Option"). During the Option period, Kirkland shall have the right to act as Operator of the Property.

Upon satisfaction of the Option, Wallbridge and Kirkland shall have formed a joint venture (the "Joint Venture") on Detour East with Kirkland acting as the operator of the Joint Venture (the "Operator") to carry on operations with respect to the Property.

Upon the formation of the Joint Venture, Kirkland will hold the right to acquire an additional 25% interest in the Property by incurring additional expenditures of $27.5 million within the first five (5) years of the formation of the Joint Venture ("Second Stage Option Period").

Upon Kirkland having incurred additional expenditures of $27.5 million during the Second Stage Option Period, Kirkland shall have earned an undivided 75% interest in the Property. The deemed expenditures on the property shall be Kirkland ($35,000,000) and Wallbridge ($11,666,667). Following the completion of the Second Stage Option Period, any additional funds required will be contributed by the Joint Venture parties based on their then proportional joint venture interests.  Should either Wallbridge or Kirkland (each a "Party" and collectively the "Parties") elect not to fund a program, its Joint Venture interest will be diluted pro-rata. If a Party commits to fund a program, and fails to contribute its share of the funding, that Party's Joint Venture interest will be diluted at three times the pro-rata rate.

If either Party's Joint Venture interest is reduced to 5% or less, that Party's Joint Venture interest shall be automatically converted to a 1% net smelter return royalty (the "NSR") and the Joint Venture shall be automatically terminated.  The surviving Party shall have a right of first offer with respect to the purchase or sale of the NSR by the non-surviving party.

Prior to September 30, 2020, the Parties shall diligently and in good faith negotiate and enter into a definitive option agreement including customary representations, warranties and conditions. In addition to the entering into of definitive agreements, completion of the transaction is conditional upon receipt of all required consents and regulatory approvals including the approval of the respective Board of Directors of each party.

About Wallbridge Mining

Wallbridge is establishing a pipeline of projects that will support sustainable 100,000 ounce-plus annual gold production as well as organic growth through exploration and scalability.

Wallbridge is currently advancing the exploration and development of its 100%-owned Fenelon Gold Property, which is located along the Detour-Fenelon Gold Trend, an emerging gold belt in northwestern Québec with an ongoing, fully funded 100,000-metre exploration drill program in 2020.

As announced on May 22, 2020, Wallbridge has completed the Plan of Arrangement whereby Wallbridge acquired all of the issued and outstanding shares of Balmoral, in an all-stock transaction. The Balmoral transaction secures for Wallbridge a buffer of several kilometres surrounding its rapidly expanding Fenelon discovery providing room for growth, as well as future mine development flexibility. The transaction, along with a recent option agreement signed with Midland Exploration, also significantly expands Wallbridge's land holdings in Québec along the Detour-Fenelon Gold Trend (from 10.5 km² to over 900.0 km²), improving Wallbridge's potential for further discoveries in this under-explored belt.

Wallbridge is also pursuing additional advanced-stage projects which would add to Wallbridge's near-term project pipeline. Wallbridge is also the operator of, and a 17.8% shareholder in, Lonmin Canada Inc., a privately-held company with a large portfolio of nickel, copper, and platinum-group metals (PGM) projects in Ontario's Sudbury Basin.
