Gold Mountain Provides Corporate Update

VANCOUVER, September 14, 2022 - Gold Mountain Mining Corp. ("Gold Mountain" or the "Company") (TSX:GMTN)(OTCQB:GMTNF)(FRA:5XFA) is pleased to report its second quarter FY2023 summary financial and operating results. The Company's interim financial statements and related management's discussion and analysis for the three and six months ended July 31, 2022, are available for download on SEDAR and on the Company's website. All amounts are expressed in Canadian dollars ("$"), unless otherwise noted.

"Since acquiring the project, Management has made a concerted effort to get the Elk back into production and into revenue generation. While we're proud of moving from permit to production in less than 18 months, the Operations team has experienced startup challenges," commented Chief Operating Officer Grant Carlson. "After our first producing quarter, our second quarter was focused on gaining an increased understanding of our resource model through the implementation of a number of initiatives."

"We completed a 3,700m in-fill drill program to tighten the in-pit spatial data. The program will define the grade control model for the next 6 to 12 months. The results to date have shown gold assays that align with the drill hole assays used to build the resource block model. In addition to the in-fill drilling, the Operations team has made an effort to improve ore control practices through drill and blast designs, extraction strategies and optimizing its pit design. The Company has also begun examining pre-concentration technologies such as Dense Media Separation which uses a heavy liquid bath to float low-density waste rock particles away from high-density gold-bearing particles. Initial test results have been encouraging and show the potential to increase the gold grade, reduce trucking costs and mitigate external dilution."

"We have also received positive results from our Phase III exploration program where we continued to hit high-grade intercepts and anticipate the results will have a positive impact on an updated resource estimate anticipated for the fourth quarter."

Highlights:

• The Company generated $968,860 of revenue in the reporting three months.
  • The reduction in revenue from Q1 was driven by the Company focusing on its in-fill drill program, improving ore control processes and optimizing its pit design.
• The Company completed its initial 3,700m in-fill drill campaign and is currently awaiting the final assay results from the lab. The in-fill drill program results to date have shown gold assays that align with the drill hole assays used to build the resource block model.
• The Company received all assay results from its Phase lll Drill Program (15,500m) which intersected significant high-grade intervals to extend the known mineralization in the Gold Creek and Siwash North zones.
  • Highlight intercepts include:
    • 65.37 g/t Au over 1.31 m including 276 g/t Au over 0.31 m
    • 48.38 g/t Au over 2.04 m including 258 g/t Au over 0.38 m
    • 59.54 g/t Au over 1.30 m Including 258 g/t Au over 0.30 m
    • 104.72 g/t Au over 0.79 m Including 167 g/t Au over 0.49 m
    • 32.32 g/t Au over 1.47 m Including 101 g/t Au over 0.47 m
    • 66.60 g/t Au over 0.95 m Including 102 g/t Au over 0.62 m
• The BC Environmental Assessment Office ruled that the Company would not need to obtain an Environmental Assessment for the proposed expansion in production at the Elk Gold Project.
  • As a result, the proposed expansion will require amendments to the Company's current permits.
  • Gold Mountain is aware and acknowledges each respective Indigenous Nation's decision-making process will continue independently from the Province of British Columbia's regulatory regime.

Mining

• During the quarter ending July 31, 2022, the Company mined 7,101 tonnes of ore and delivered 557 AuOz.
• Ore mining was slowed during the quarter primarily due to:
  • Completing the in-fill drill program (87 holes, 3,700m).
  • Evaluating improved ore blasting designs, and ore recovery practices.
  • The Company also removed 599,425 tonnes of waste on the 1605 and 1595 benches with the goal of increasing the minimum bench width in the pit bottom which allows for more efficient and selective ore mining.

Ore Mining Initiatives

• The Company has implemented a number of initiatives which have provided a better understanding of the ore body. These initiatives included implementing a robust in-fill drill program as well as a number of ore control practices.
• In-fill Drilling
  • The in-fill drill program results to date have shown gold assays that align with the drill hole assays used to build the resource block model. The Company intends to use the in-fill drill data to improve the accuracy of the Company's production forecasting.
  • A total of 87 in-fill holes were completed to better define the tonnes and grade of the mine plan over the next 12 months.
• Ore Control Practices
  • Optimized drill and blast design to fragment ore without causing additional dilution.
  • Implemented new ore extraction methodologies to efficiently separate ore from waste at the dig face.
• The Company anticipates continuing to implement the initiatives set out above to refine its existing grade control and sampling procedures.

DMS Evaluation

• Initial test results from pre-concentration technologies such as Dense Media Separation ("DMS"), which uses a heavy liquid bath to float low-density waste rock particles away from high-density gold-bearing particles, have yielded encouraging results and the Company is evaluating incorporating them into future mine plans.
• Preliminary DMS test work indicated the potential for increased waste rejection from the ore stream while maintaining gold recovery.
• The Company will continue to evaluate DMS as the initial test work indicates the potential to increase the gold grade in the ore, reduce trucking costs and mitigate any external dilution.

Exploration

Phase lll

• During the second quarter the Company completed its Phase lll exploration program which totaled 15,500 meters.
• The campaign successfully expanded several important areas of the vein model and continued to intercept high gold grades.
• Drilling on the 1300 vein extended its mineralization down-dip another 150m, reaching a depth of over 400m below the surface.
• Additional drilling successfully targeted areas of high-grade inferred resources in the current mineral resource estimate in order to increase the level of geological confidence in those zones.
• The strong results from the Phase III campaign are planned to be incorporated into an updated mineral resource estimate anticipated to be completed in Q4.
• Below is a table of selected core drill results from the Phase III drill program. A complete list of all drill results to date have been posted to the Company's website at www.Gold-Mountain.ca :

Phase IV

• Phase lV Drilling began in August 2022, targeting the Gold Creek, Lake, South and Elusive zones.
• The initial results from the Phase IV campaign are planned to be incorporated into the updated mineral resource estimate anticipated to be completed in Q4.
• The Company has put its Phase IV exploration drill program on hold to focus on in-fill drilling and the ore control practices discussed above. The Company anticipates restarting its Phase IV drill program in early 2023.

Expansion

• The Company has begun to lay the groundwork for the expansion contemplated in the Elk Gold Project's technical report which sees the Company scaling up to 324,000 tonnes/year and 65,000 oz/annum (the "Expansion")^[1].
• In August 2022, the Company received a decision from the Environmental Assessment Office ruling that the Company will not need to obtain an Environmental Assessment for the proposed Expansion.
• The Expansion will require amendments to the Company's current Mine Permits.
• Gold Mountain is aware and acknowledges each respective Indigenous Nation's decision-making process will continue independently from the Province of British Columbia's regulatory regime.
• Over the past 24 months, the Company has made a concerted effort to build strong relationships with communities that are affected by the development of the Elk Gold Project. Gold Mountain looks forward to continued collaboration with all Indigenous Nations that have interests in the Elk Gold mine. The Company also wishes to communicate that there is no time limit on direct engagement and consultation between the Company and each respective Indigenous Nation.

Mergers & Acquisitions

• The Company is actively evaluating M&A opportunities with a focus on assets with near-term production potential.
