VANCOUVER, BC

June 28, 2021

/CNW/ - Mineral Mountain Resources Ltd. ("

Mineral Mountain

"

or the "

Company

") (TSXV: MMV) (MNRLF: OTCQX) (FRANKFURT: M8M) is pleased to announce

that, following a successful mapping and sampling program conducted last month by the Company's

Chief Geologist,

Jeff Hrncir

, about 4.8 kilometers southwest of the Company's main gold target, the

Standby Mine, a 2.5 km long north-northwest trending band of well mineralized, metamorphosed and

folded chert-grunerite of the Rochford Formation recording some of the highest grade gold values

sampled in the

Rochford

District to date has recently been staked by Mineral Mountain. A total of 15

unpatented BLM claims totaling approximately 280 acres were staked to cover the 2.5 km length of

this mineralized trend which includes three historical high-grade gold producers; the

Black Eagle

situated at the southern end of this trend, and the

King of the West

and

Yellow Bird

Deposits

both

near the north end. This new mineralized trend in the district has seen little modern exploration

despite the significant potential to outline large volumes of high-grade mineralized iron formation

beginning at surface.

The

King of the West Mine

was discovered in 1900 and explored sporadically until 1936 through a

shaft

45 m

deep with

69 m

of drifts and numerous small open cuts and test pits. The mine reportedly

produced

1,547 ounces of gold

at an average recovered grade of

7.78 g/t Au (0.25 opt Au)

from

ores averaging from

10.89 g/t Au to 13.06 g/t Au

(

0.35 to 0.42 opt Au) head grade

. Gold

mineralization is hosted in sulfide-rich (pyrrhotite-pyrite-arsenopyrite) cummingtonite-facies iron

formation within a small parasitic fold hinge on a larger anticlinal fold structure. Channel sampling at

the bottom of the main open cut at the

King of the West Mine

by Homestake Mine geologists in

1926 (Geological Survey Bulletin 1332-A) recorded a value of

8.09 g/t Au across

9.10m

(

0.26 opt

Au across 29.85 ft.).

On the 75-foot (

23 m

) level two separate ore shoots graded

8.40 g/t Au over

4.88 m

and 29.85 g/t Au over

2.74 m

.

Shallow rotary holes drilled between 1978 and 1984 to

maximum depths of just

90 m

from surface intercepted significant gold grades including

5.88 g/t Au

over

6.10 m

, 8.02 g/t Au over

3.05 m

and 5.85 g/t Au over

9.14 m

.

The nearby

Yellow Bird Mine

is located

210 m

northwest of the King of the West. Its history is

poorly documented but the mine reportedly produced significant gold in the 1890's, at least 1,900

ounces, from a series of shallow open cuts in sulfide-rich ore. The structural setting of the mine is

unclear due to poor outcrop but is evidently located within a northeast-striking shear zone cutting the

east limb of a small anticline in the

Rochford

iron formation. The King of the West-Yellow Bird area

is marked by a strong arsenic soil anomaly extending for over

400 m

along strike containing values

greater than

3,500 ppm As

, reflecting the presence of highly oxidized arsenopyrite-rich

mineralization.

The

Black Eagle Mine

is located on the west limb of a significant synclinal fold in the

Rochford

iron

formation. The mine was developed historically through five shafts ranging from 23 to

37 m

deep, a

244-m adit and 120-

150 m

of drifts and crosscuts spread out over a strike length greater than

300

m

. Although ore was found in numerous places in these workings assaying from

10.85 to 18.66 g/t

Au

, the ores were unoxidized and very poor recovery of gold values from the sulfide-rich ores

curtailed production and further development. A shallow rotary hole drilled in 1978 at the Black Eagle

intercepted

11.82 g/t Au over

1.83m

(

0.38 opt Au over 6.00 ft.)

from 27.4 to

29.3 m

and

8.40 g/t

Au over

1.83m

(0.27 opt Au over 6.0 ft)

from 32.9 to

34.8 m

. Noranda explored the property from

1986-1988, producing a strong arsenic-in-soil anomaly measuring 150 by

230 m

across, with internal

gold anomalies. Trenching within this zone produced highly encouraging gold mineralization, including

4.45 g/t Au over

2.74m

(0.143 opt Au over 8.99 ft.)

and

4.73 g/t Au over

1.53m

(0.152 opt Au

over 5.02 ft.)

. A single reverse circulation (RC) hole, BC-89-6, intercepted more than

60 m

of

Rochford

iron formation with the structurally thickened hinge region of the Black Eagle syncline. A

cherty gossan associated with a felsic tuffaceous horizon above the

Rochford

iron formation is also

mineralized for at least

1,070 m

along strike a few hundred meters west of the Black Eagle trend.

Rock chip samples along this gossan contain values of 500 ppb to 1,000 ppb Au and this zone has

never been systematically explored or drilled.

Jeff Hrncir

, the Company's Chief Geologist commented: "

The newly staked Black Eagle-King of the

West trend further demonstrates the uniquely underexplored but highly prospective nature of the

Rochford

District. The recognition of the trend stems from ongoing technical studies of the

Rochford

District that highlighted the potential of this area for near-surface high-grade gold

mineralization, which has been confirmed through recent sampling and mapping efforts.

Exploration at the Black Eagle and King of the West-Yellow Bird Mines has been minimal to

maximum depths of just a few hundred meters, with almost no exploration outside the historic

mines, and

no previous company has cohesively explored this trend as a single exploration

target

. The 10 km stretch of Castle Creek downstream of the Black Eagle-King of the West belt of

mineralized Rochford Formation was one of the largest placer gold areas of the Black Hills

(estimated production of as much as several hundred thousand ounces) and supported the only

floating dredge in the region. Castle Creek gold is notably coarse and nuggety and may have been

derived from high-grade veins and shoots within the iron formation in the vicinity of the Black

Eagle-King of the West mines. Previous drilling has demonstrated that the Black Eagle, in

particular, has the potential to host extremely large volumes of mineralized

Rochford

iron

formation within the large-scale syncline structure."

About Mineral Mountain Resources and the Rochford Gold Project

Mineral Mountain Resources Ltd., through its wholly owned subsidiary Mineral Mountain Resources

(SD) Inc., with a strong technical and highly experienced team, is focused on the exploration and, if

warranted, development of its 100%-owned

Rochford Gold Project

physically situated 26

kilometers south of the world's richest and largest orogenic gold deposits, the Homestake Mine,

within the highly prospective

Homestake Gold Belt

in the Black Hills of

South Dakota, U.S.A.

With the staking of the Black Eagle-King of the West-Yellow Bird Trend, the Rochford Project now

covers

7,835 acres

, covering four major trends of 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.

Since 2013, the Company has continued to expand its land position in the

Rochford

gold district by

professional claim staking and by purchasing strategically located private properties that fall along

two of the major sub-parallel structural trends that host Ledge-type gold mineralization. The

Company now owns the largest land position in the

Rochford

greenstone belt and now possesses by

far the largest and most comprehensive database for the district in modern day exploration history!

The Rochford Project is vastly under-explored and has the potential to host several district scale

gold discoveries.
