MAS Gold Corp. and Comstock Metals Ltd. Sign Letter of Intent for MAS Gold to Acquire 100% of Comstock's Preview SW Gold Project La Ronge

Comstock's 843 hectare Preview SW Property is contiguous with MAS Gold's Preview-North Property in the La Ronge Gold Belt of northeastern Saskatchewan (see Figure 1). The Preview SW Property and portions of the Preview-North properties are located within the Mineral Exploration Zone of Lac La Ronge Provincial Park.

The addition of the Preview SW Property is synergistic with MAS Gold's deposits, significantly expanding MAS Gold's mineral asset base in the La Ronge Gold Belt.

The Preview SW Property's gold deposit hosts historical resources, at a 0.50 gram/tonne gold (g/t Au) cut-off grade (Technical Report, Simpson 2016 ¹):

• An historical Indicated Mineral Resource containing 158,300 ounces of gold (2.61 million tonnes grading 1.89 g/t Au); and
• An historical Inferred Mineral Resource containing 270,800 ounces of gold (5.70 million tonnes grading 1.48 g/t Au).

Upon the closing of the Proposed Transaction Comstock will have the right to appoint one director for a minimum of two years. Comstock will also provide additional funding in the amount of $200,000, to be spent in Q1 2022 in conjunction with input from MAS Gold, exploring its Preview SW Property prior to closing of the Proposed Transaction. A definitive agreement will be signed prior to January 15th,2022 and closing is anticipated in March, 2022 after both companies' AGM and shareholder vote anticipated to take place in late February, 2022.

Jim Engdahl, MAS Gold's President and CEO remarked, "We are very excited with the friendly acquisition of the Preview SW Property's gold deposit located within 10 kilometres of MAS Gold's North Lake gold deposit, the recently acquired former Contact Lake gold mine and Point gold deposit. Upon completion of the Proposed Transaction this high-quality asset combined with MAS Gold's mineral portfolio, which includes the recently updated North Lake and Greywacke North mineral resources announced December 6, 2021 and December 9, 2021, respectively, MAS Gold will become one of Saskatchewan's biggest gold developers."

Jim added, "Under the terms of the Proposed Transaction Steven Goldman, the President and CEO of Comstock will join the MAS Gold. We look forward to working with him."

Mr. Goldman, President commented, "On behalf of Comstock, I believe the Proposed Transaction will be highly advantageous and synergistic for both Comstock's and MAS Gold's shareholders. We are delighted to have the opportunity to pass Comstock's Preview SW gold project to MAS Gold where we believe the combination of gold resources, MAS Gold's experienced management team, and technical mining talent, will quickly accelerate the creation of a significant gold deposit in the La Ronge Gold Belt. Ultimately we believe that the Proposed Transaction will help create significant shareholder value in the years to come for both Comstock's and MAS Gold's shareholders."

For the purposes of this News Release and MAS Gold, the 2016 Simpson Technical Report is treated as historical. A Qualified Person has not done sufficient work to classify the historical estimate as a current mineral resource and MAS gold is not treating this historical estimate as current mineral resources.

MAS Gold and Comstock consider the Preview SW historical mineral resource estimate to be relevant and reliable. The Preview SW estimate was constrained by 3D wireframes representing zones of high shear intensity and grade continuity. The drill database comprised 162 core holes totaling 26,250 m drilled between 1985 and 2013. Drill hole data was composited on 1 metre intervals and composites were capped at 50 g/t Au. Final gold grades were estimated using the inverse distance method to the 3rd power (ID3). Bulk density values were assigned to blocks according to lithology based on specific gravity field measurements. A block model was created in Gemcom-Surpac Vision© software using a block size 5 x 5 x 5 metres. Mineral resources amenable to open pit mining methods were constrained using a Lerchs-Grossmann optimized pit. Assumptions include US$1,300/oz Au, 90% Au recovery, US$2.50/tonne mining cost, US$15.50/tonne process, and G&A cost. No allowances have been made for mining losses and dilution. Pit slope angle of 45°.

The Preview SW estimate was classified using the definitions set out in CIM Definition Standards for Mineral Resources and Mineral Reserves (2010), which was superseded by CIM (2014). Similarly, the Preview SW estimate predates CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines (2019). To verify the historical estimate as a current mineral resource a Qualified Person would need to prepare an updated mineral resource estimate and NI 43-101 technical report with respect to the Preview SW Property that incorporates additional drilling completed since the since 2013, which includes 24 holes totaling 4,700 metres targeting the Preview North zone and Preview SW during 2017 and 2018 (7 holes totalling 1,850 m at the Preview SW).

About MAS Gold Corp.

MAS Gold Corp. is a Canadian mineral exploration company focused on gold exploration projects in the prospective La Ronge Gold Belt of Saskatchewan. In the belt, MAS Gold operates four properties including the Preview-North, Greywacke Lake, Elizabeth Lake and Henry Lake Properties that extend along segments totaling roughly 60 kilometres of the geologically prospective La Ronge, Kisseynew and Glennie Domains that make up the La Ronge Gold Belt (see Figure 1).

MAS Gold's holdings include the North Lake, Greywacke North, Bakos (Contact Lake) and Point gold deposits and the historically defined Elizabeth Lake copper-gold volcanic-hosted massive sulphide deposit within four properties totalling 34,703.4 hectares (85,753.8 acres).

The North Lake deposit located at the Preview-North Property is estimated to contain an Inferred Mineral Resource of 18,100,000 t grading 0.85 g/t Au, hence 494,000 contained ounces of gold. The Technical Report about the updated Mineral Resource estimate will be filed in January, 2022 (see MAS Gold news release dated December 9, 2021).

The Greywacke North deposit, which hosts multiple known stratabound, high-grade gold-bearing zones, has an updated, combined openpit and underground Indicated Mineral Resource of 645,000 t averaging 4.90 g/t Au for 101,000 insitu ounces of gold (600,000 t at 4.89 g/t Au, and 45,000t at 5.03 g/t Au, respectively), plus a combined openpit and underground Inferred Mineral Resource of 410,000 t averaging 4.12 g/t Au for 55,000 insitu ounces of gold (35,000 t at 1.97 g/t Au, and 375,000 t at 4.33 g/t Au, respectively). The Indicated and Inferred Mineral Resources were estimated using openpit and underground cut-off grades of 0.65 g/t Au and 1.75 g/t Au, respectively. The Technical Report about the updated Mineral Resource estimate will be filed in January, 2022 (see MAS Gold news release dated December 6, 2021).

The Bakos deposit, located on the former Contact Lake Mine holding, was first identified by Saskatchewan Mining Development Corporation (SMDC; later Cameco Corporation) exploration field crews in 1984. Operations were conducted from December 1994 until closure in December 1998. Historical production and recovery values for the entire operation included 188,185 ounces gold produced from 1,006,673 tonnes processed with a head grade of 6.16 g/t Au at a recovery rate o 95% (Leniuk, G., B. Bharadwaj, G. Alderman & R. Wyka: Cameco Corporation Contact Lake Operation, Final Report, January, 1999). The mine was shut down during low metals prices, reportedly leaving undeveloped material in place.(see MAS Gold news release dated September 13, 2021).

The Point deposit has been the subject of multiple drill campaigns dating to the 1980's when Saskatchewan Mining and Development Corporation (SMDC; later Cameco) drilled 43 core holes. MAS gold completed 13 additional holes in 2019, intersecting multiple high-grade intercepts including 7.0 metres grading 14.99 g/t Au from 20.0 to 27.0 metres (see MAS Gold news release dated June 25, 2019).

About Comstock Metals Ltd.

Comstock Metals has been advancing the Preview SW Gold Project, a resource-stage gold project in the La Ronge district of Saskatchewan (see Figure 1).
