Sulliden Mining Capital Inc. (Smc: TSX) Announces 52.4 M at 1.14 G/T GOLD Equivalent Adjacent to Eldorado’S Triangle MINE ON Its 100% Owned East- Sullivan Formerly Producing Property

Drill Results

SULLIDEN MINING CAPITAL INC. (SMC: TSX) ANNOUNCES

52.4 M AT 1.14 G/T GOLD EQUIVALENT ADJACENT TO

ELDORADO’S TRIANGLE MINE ON ITS 100% OWNED EAST-

SULLIVAN FORMERLY PRODUCING PROPERTY

Press Release – February 24, 2021

Toronto, Ontario, Canada

Highlights include:

• 52.4 m at 0.45% Cu and 0.44g/t Au, or 1.14 g/t Au EQ

• 20.2 m at 0.66% Cu and 0.40 g/t Au, or 1.43 g/t Au EQ

• 9.0 m at 0.95% Cu and 0.14 g/t Au, or 1.62 g/t Au EQ

Sulliden Mining Capital Inc. (“Sulliden” or the “ Company”) (TSX: SMC) is pleased to announce

the results of its 2019 and 2020 drilling campaign s on its 100% owned East -Sullivan property

(the “Property”). The Property is located in the heart of one of the most prolific gold and copper

greenstone belts in the world, which is within the historical minin g camp of Val -d’Or, Quebec,

Canada. The Property is adjacent to and less than 2 km away from Eldorado Gold Corp. ’s

Lamaque mining operation (Triangle zone, Figure 1) . Note that Eldorado has entered into a

definitive arrangement agreement pursuant to which it is expected that Eldorado will acquire

100% of QMX Gold Corp. (“QMX”), which owns properties directly north of the Property (see

QMX’s press release dated January 21, 2021). QMX reports an indicated mineral resource of 397

KOz at an average grade of 1.67 g/t Au (see QMX’s press release dated December 2, 2020).

The Property also hosts the former East -Sullivan mine, a major producer that operated from

1949 to 1966. Ore was historically mined from a multi-lens, polymetallic base metal deposit (Cu,

Zn, Au, Ag, ±Pb) and past production amounted to 14,968,918 tonnes at an average of 1.05% Cu,

0.78% Zn, 0.38 g/t Au and 10.63 g/t Ag according to the compilation of yearly production figures

produced by the Department of Mines of the Province of Quebec.

Note the underground extension of the Triangle operation in dashed line.

Drilling on the Property was conducted in two phases:

1- In September 201 9, Sulliden completed drill holes SU-19-001 and SU -19-002 to tes t the

eastern extension of the East -Sullivan past producing mine. Both SU -19-001 and SU-19-

002 intersected mineralization. Highlights are 52.4 meters grading 0.45% Cu and 0.44

g/t Au for the first hole, and 20.2 meters grading 0.66% Cu and 0.4 g/t Au for the

second hole (Table 1).

2- In October 2020, drill holes SU -20-001 and SU-20-002 tested a magnetic anomaly at the

western contact of the East -Sullivan pluton and the western extension of the East-

Sullivan past producing mine, respectively. Drillhole SU -20-002 intersected 9 meters

averaging 0.95% Cu and 0.14 g/t Au (Table 1).

Drill hole coordinates and locations are shown in Table 2 and Figure 1.

A compilation of surface and underground dr ill data respecting the former East-Sullivan mine

was completed in 2020, which lead management to a better understanding of mineralization

trends and controls. The eastern extension of the mineralization straddle s the East -Sullivan

pluton contact oriented N50E, whereas the w estern extension is oriented east -west. The true

thickness of the mineralized drill intervals could thus be estimated and is reported in Table 1.

“The recent exploration campaign delivered positive results and ex citing news for Sulliden ,”

stated Stéphane Amireault, a consultant and member of the board of dire ctors of Sulliden. He

continued, “It confirms the potential of the Property and potential extensions around the past

producing East-Sullivan mine.”

“We are bullish o n the price of both copper and gold, and we believe recent market actio n

suggests that we may be i n for a strong market in precious and base metals. Many mines are

discovered in the “shadow” of existing mines, and this may be no exception. With excellent

infrastructure in place, we are optimistic that we could have an exciti ng project here. W e have

an excellent track record of discovering and developing mines, including the Shahuindo mine in

Peru (which is producing over 200,000 ounces of gold per year a nd was sold to Pan American

Silver Corp.) and the Troilus mine, now in an advanced developm ent stag e in Chibougamau,

Quebec,” said Stan Bharti, CEO of Sulliden.

National Instrument 43-101 – Standards of Disclosure for Mineral Projects.

Quality Assurance/Control

Sulliden operates its exploration programs according to industry best practices and employs

rigorous quality assurance and quality control pro cedures. All results are based on half -core

samples of NQ-size diamond drill c ore. In 2019, samples were prepared and assayed at AGAT

Laboratories in Val -d’Or. The assay results for Cu, Zn, Pb, and Ag are obtained from an Agua

Regia digestion and ICP-AAS finish. In 2020, samples were prepared and assayed at ALS Chemex

Laboratories in Val-d’Or. The assay results for Cu, Zn, Pb, and Ag are obtained from a four acid

digestion and ICP-MS finish. All Au assays for the 2019 and 2020 drill programs are based on fire

assay analysis of a 30 g charge followed by an atomic absorption finish. Certified standard

reference materials, field duplicate and blank samples were inserted regularly and were closely

monitored to ensure the quality of the data.

About the East-Sullivan Property:

The East -Sullivan property is located 5 kilometers to the southeast of the city of Val -d’Or. It

contains the former East -Sullivan polymetallic deposit that produced 14,968,918 tonnes of ore

at an average of 1.05% Cu, 0.78% Zn, 0.38 g/t Au and 10.63 g/t Ag from 24 lenses starting from

surface and extending to a vertical depth of 930 meters. Mineralization consists of sulphide

dissemination, sulphide stringers, as well as semi -massive and massive zones characterized by

chalcopyrite, sphale rite, py rrhotite, and pyrit e hosted in altered volcanic rock units. The

Property also hosts a structurally controlled gold zone, located 750 meters to the east of a

former mine . Historical drillholes revealed shear hosted quartz veining measuring up to 6

meters thick.
