Second New Gold Discovery Mineral Mountain Records Multiple High Grade Grab Samples Up to 138 GPT Au Along a Mineralized BIF 3.7 km Long

VANCOUVER, Feb. 8, 2023 - Mineral Mountain Resources Ltd. ("Mineral Mountain" or the "Company") (TSV: MMV) (OTCQB: MNRLF) (FRANKFURT: M8M) is pleased to announce its second new important discovery with the impressive assay results of up to 138 g/t Au (4.27 opt Au) from a grab sampling program performed last fall from historical workings along the 3.7 km long King of the West-Yellow Bird-Black Eagle Mines Trend collectively referred to as the "King of the West Trend" in the Company's News Release dated June 28, 2021 and located in the southwestern portion of the Rochford Mining District. The King of the West Mine is located 8 km southwest of Mineral Mountain's new high-grade Standard Mine Trend discovery announced on February 2, 2023.These samples confirm the outstanding nature of surface mineralization over a large area around the King of the West Mine (Fig 1).

Assay results from grab samples collected around the historical King of the West and Yellow Bird Mines included:

* It should be noted that grab samples are not representative of the actual tenor of the mineral occurrence and are only used to measure and identify distribution of the precious minerals present along this trend.

These grab samples are in line with results of previous underground channel samples collected while the shallow mine workings were still accessible in the early 20^th Century that are known to MMV, such as 9.1 m @ 8.15 g/t Au, 15 m @ 16.0 g/t Au, and 2.44 m @ 13.2 g/t Au across the King of the West mineralized structure at depths of less than 20 m below surface and vertical channel samples of 10.67 m @ 13.33 g/t Au and 15.2 m @ 15.55 g/t Au collected in the Yellow Bird shaft.

Grab samples were collected from dumps of the three historic shafts at the Yellow Bird and King of the West Mines, a collapsed overhand stope at the Yellow Bird, and surrounding exploratory open cuts over an area of 400 x 300 m. Several grab samples contained multiple grains of visible gold (Fig 2). Outcrop is generally poor in the low-relief topography around the mines, although the Rochford iron formation can be followed through ferruginous cherty float, quartz veining and deep yellow-orange gossaniferous soils. The iron formation can be mapped through several fold structures along a prominent NE-striking fault-shear zone for at least 1,200 m and is up to 20 m wide at the King of the West Mine. As a result of mapping, the length of the King of the West Trend has more than doubled to 3.7 km along strike, within which over 1,200 shallow prospect pits, trenches and open cuts, 78 larger open cuts or shafts, and 24 tunnels have been mapped. An area measuring nearly 1 km by 1 km around the King of the West Mine contains more than half of these surveyed workings, making it one of the most heavily prospected areas known in the Rochford District.

The King of the West and Yellow Bird Mines were discovered in 1897 and 1898 respectively and worked through numerous shallow open cuts. Approximately 2,000 tons of ore were mined from the King of the West at a grade of 20 g/t Au, while close to 1,850 ounces were produced at the Yellow Bird. In 1902, both mines were consolidated by the Golden West Company and developed by additional open cuts and 275 meters of underground workings. Fifteen diamond holes were drilled, with a few reportedly encountering excellent mineralization up to 38 g/t Au over unknown widths.

From 1934 to 1936, the King of the West Syndicate was organized to explore the property. Exploration consisted of 289 m of drifting off a shaft that reached an ultimate depth of just 49 m and 1,049 m of diamond drilling. An extensive surface sampling campaign consisting of 2,500 grab, trench and channel samples encountered additional ore zones containing up to 124 g/t Au. Two ore shoots found at the King of the West Mine on the 23-m level were found to average 4.88 m @ 8.3 g/t Au and 2.74 m @ 10.6 g/t Au. Very limited short-range diamond drilling down-dip of one of three ore shoots targeted by the Syndicate encountered multiple intercepts in the range of 9-15 g/t Au with the best surviving intercept of 1.52 m @ 78.4 g/t Au. The ore zone has never been explored more than 50 m below surface. In 1936, the Syndicate milled 6,990 tons of ore with a head grade of 6.9 g/t Au but recovered just a fraction of the expected gold due to milling complications and ceased activity on the property.

From 1978-1984 Bobcat Properties and Minerals Management drilled sixteen shallow rotary holes at King of the West, all to depths of <100 m. Noranda leased the property in 1986 and a map of the prior drilling made available to Noranda included six holes with significant intercepts >0.10 oz/ton Au. Three of these holes contained 6.10 m @ 5.88 g/t Au, 3.05 m @ 8.02 g/t Au and 9.14 m @ 5.85 g/t Au.

*The preceding disclosure is based on information that is historical in nature and can not be treated as NI-43-101 compliant verified by a qualified person. The historical estimates should not be relied upon and there can be no assurance that any of the mineralization, in whole or part, will ever become economically viable.

Nelson Baker, President and CEO commented: "Mineral Mountain's recent advances in studying the geology and history of the Rochford District have greatly enhanced the exploration potential of the company's district-scale land holdings and led to the identification of numerous very high-quality drill targets. The last serious mapping was performed over 60 years ago without the aid of geophysical tools and without the benefit of an understanding of iron formation-hosted gold deposits in general. A new structural synthesis and mapping approach developed by Mineral Mountain's technical team has highlighted the unique potential of the King of the West Trend for near-surface high-grade gold mineralization over a large area. This has been confirmed by the presence of excellent gold values in multiple targets separated by hundreds of meters along strike. Sampling to date has focused on the northern part of the King of the West Trend, however four other historic mines, including the Black Eagle, further south have yet to be examined in any detail. We are planning an aggressive summer field program to further refine these high-quality drill targets in advance of an anticipated drill program later this year, which is in the permitting stage."

The technical information in this news release has been prepared in accordance with Canadian regulatory requirements set out in National Instrument 43-101 and reviewed and approved by Nelson W. Baker, BSc Geological Engineering, the President and CEO of Mineral Mountain Resources Ltd. and a Qualified Person for this project. All exploration activities at the Standby Mine and at the Company's other activities in the Rochford District are carried out under the strict supervision of Kevin Leonard, P.Geo., also a Qualified Person for this project.

Mineral Mountain Resources Ltd., through its wholly owned subsidiary Mineral Mountain Resources (SD) Inc., began exploring in the Black Hills of South Dakota, USA in July 2012. The Company recognized that the Homestake Gold Trend was not well explored using modern technology and the potential of discovering another similar Homestake-style gold deposit with scale was above average. Since 2012, the Company has expended over $13 million USD in systematic, "state of the art" exploration with a strong technical and highly experienced team largely focused on its 100%-owned Rochford Gold Project physically situated 26 kilometers south of the world's richest and largest orogenic gold deposits, the Homestake Mine.

With the recent staking of the 3.7 kilometer long trend linking the Black Eagle-King of the West-Yellow Bird Trend, the Rochford Gold Project now covers over 8,224 acres, covering at least four large magnetic bodies that are considered to be structurally thickened auriferous iron formation comparable to the ledge-type gold mineralization developed at the Homestake Mine. The Standby Mine Target, the Company's flagship project is the most advanced gold exploration target within the Rochford Gold Project is believed to possess the requisite volume of altered and gold-mineralized iron formation needed to contain a large, economic gold resource. Financing is in progress to drill 9,000 m at the Standby Mine.
