Blue Thunder Initiates 2021 Field Program to Investigate Encouraging 2020 Exploration Results

Toronto, May 26, 2021 - Blue Thunder Mining Inc. (TSXV: BLUE) ("Blue Thunder" or "the Company") is pleased to announce the commencement of its 2021 field program, including drilling, on the 100%-owned Muus Project, situated in the Chibougamau Gold District, Quebec. The program follows up on encouraging results reported in late 2020 (see January 21, 2021 news release).

"2021 promises to be a very exciting year for Blue Thunder: our exploration momentum has grown steadily since we aggregated, through staking and acquisition, our large and strategically situated land package of approximately 52,000 hectares (ha) (approximately 130,000 acres). This is the largest aggregate claim block in an extremely exciting area for mineral exploration. In late 2020 we released encouraging drilling results from both the Fancamp property and a new gold-mineralized zone (the "Discovery Zone") on the Muus property. Also, the recent addition of Mr. Jean Francois Metail to our team has sparked new thinking and energy into our efforts. We have many reasons to be optimistic that we will make a significant discovery in 2021," said Chad Williams, Executive Chairman and Interim CEO.

2021 HIGHLIGHTS

• 2,600 metres of diamond-drilling planned in Phase 1 program
• Till and soil sampling surveys underway both at the Muus and Fancamp properties
• Property-scale 3-D modeling and targeting work

2021 Till and Soil Geochemical Program

Blue Thunder has retained IOS Services Géoscientifiques Inc. ("IOS") to complete a till sampling program across the Company's Muus property. A total of 175 till samples will be collected and processed for gold grain content by IOS using their proprietary automated analysis technique. The IOS gold-in-till approach has been successfully deployed in other gold districts in the Abitibi region of Québec and other gold districts across Canada and it played an important role in numerous discoveries such as Kenorland Minerals Ltd's recent discovery in the Frotet-Evans Greenstone Belt located north of Muus. Results from the IOS till survey are expected by mid-summer.

The company has also commenced a soil sampling program at its Fancamp and Muus properties, on select target areas. The first phase of the soil-sampling program is designed to collect approximately 3,000 samples.

Ongoing 3-D Modeling and Target Generation

Results from the 2021 till- and soil-geochemical programs will be used to augment the ongoing property-scale 3-D modeling work being carried out for the Muus Project, in which multiple layers of data are being integrated to generate a property-wide structural and geological framework.

This 3-D model will be used to identify prospective zones associated with the key regional structures that transect the Muus Project, namely the Guercheville Deformation Zone, the Fancamp Deformation Zone and the Philibert-Joe Mann Deformation Zone.

These deformation zones are associated with many of the known gold deposits and occurrences in the District, including the recently discovered Nelligan^[1] and Monster^[2] Lake gold deposits, which occur on adjacent properties and on strike with Blue Thunder claims.

Vanstar Mining Resources Inc. recently announced that its joint-venture partner Iamgold Corporation ("Iamgold") (Iamgold 75%, Vanstar 25%) is expected to begin a 9,000 to 10,000 metre diamond-drilling campaign at Nelligan. Interestingly, approximately half of this drilling budget appears to be dedicated to step-outs to the west of the Nelligan deposit in the direction of the Muus Property.

2021 Drilling Program

The Company has budgeted 2,600 metres of Phase 1 diamond-drilling for the 2021 field program. A number of targets will be tested on the Muus property targeting "Nelligan-style" sedimentary-hosted gold mineralization, including extensions of hole MUUS20-01 in the Discovery Zone and Induced Polarization anomalies identified over the Tectonic Grid.

QAQC and Qualified Person

COVID-19

On February 22, 2021, the government of Québec down-graded the "Nord-du-Québec" region, in which the Company's Muus Project occurs, from Level 4 (Red) to Level 3 (Orange), which was recently followed by a further downgrade to Level 2 (Yellow) on March 26, 2021. The Company continues to monitor developments related to the COVID-19 pandemic very closely.

In conformity with guidelines proposed by the Québec government's "Commission des normes, de l'équité, de la santé et de la sécurité du travail" (CNESST) the Company has implemented a strict COVID-19 management plan that complies with provincial government directives and guidelines with the main objective to safeguard the health and safety of our workers, stakeholders and local community members in light of the COVID-19 pandemic.
