GSilver is not treating these estimates as current mineral resources as a qualified person on

behalf of GSilver has not done sufficient work to classify these estimates as current mineral

resources. (2)

Ramon Davila, President and Director of GSilver said, “This acquisition will prove instantly accretive; the Topia

Mine is currently producing and will immediately lift GSilver’s production profile. Within the Guanajuato mining

district, the San Ignacio and Valenciana mines were put on care and maintenance less than eight months ago

only due to a lack of available tailings facilities; GSilver plans to swiftly re-start production from these mines and

process the mineralised material using the excess capacity at our nearby El Cubo production facilities (“ El

Cubo”). This acquisition keeps us on course to expeditiously establish GSilver as a mid -tier precious metals

producer in Mexico.”

Purchase of the Great Panther MMR Assets:

The Company has signed a binding definitive agreement with Great Panther (the "GP Agreement ") to acquire

100% of the shares of Great Panther’s Mexican subsidiary , MMR. MMR’s combined Mexican assets include

three mines, two floatation processing facilities, substantial historical measured, indicated, and inferred

resources(2), and 25,000 hectares of mineral claims as more particularly described below.

The GP Agreement:

Chairman and CEO James Anderson said: "We are delighted to have come to this agreement with Great Panther,

and we welcome them becoming a significant shareholder of our Company. The Great Panther Mexican assets

fit well into our plan to expand precious metals production in central Mexico . The MMR Acquisition further

demonstrates our commitment to consolidat ing the Guanajuato m ining district, which has an established 480-

year mining history of precious metals production. The immediate availability of mineralised material from the

San Ignacio and Valenciana mines will allow GSilver to fill our El Cubo mill’s excess capacity in Guanajuato .

Together with ongoing production from the Topia Mine in Durango, our production expansion will be immediate

and substantial. Additionally, the integration of the GSilver mining claims with the claims of Great Panther will

open new exploration possibilities in the district that were not possible before this transaction. We thank our

European resource lender “OCIM” and our offtake partners “Ocean Partners (UK) Ltd.” for providing important

lead financing orders for this transaction.”

On closing of the MMR Acquisition GSilver will pay, subject to certain closing adjustments, US$14.7M to Great

Panther as follows:

• US$8.0M in cash, subject to adjustments.

3

• US$6.7M in GSilver common shares at a deemed price of C$0.335 per share, for a total of 25,787,200

GSilver shares (the “Consideration Shares”).

GSilver has also agreed to pay Great Panther up to an additional US$2.0M in contingent payments based on the

following:

 US$500,000 upon GSilver producing 2,500,000 ounces of silver from the purchased MMR

assets.

 US$750,000 if the price of silver closes at or above US$27.50 per ounce for 30 consecutive

days within two years after closing.

 US$750,000 if the price of silver closes at or above US$30.00 per ounce for 30 consecutive

days within three years after closing.

Closing of the GP Agreement is subject to satisfaction of certain closing conditions including receipt of all

requisite third party approvals and the acceptance of the TSX Venture Exchange (the “TSXV”).

Financing for the MMR Acquisition:

US$5.0M Credit Facility:

GSilver is pleased to announce that it has signed a concentrate pre- payment facility term sheet (the “ OP

Facility”) with Ocean Partners (UK), a metals off- take and trading firm , to provide US$5.0 M of financing to be

used as a portion of GSilver’s acquisition price for MMR. The OP Facility will be for a term of 24-months, secured

by a share pledge over MMR, which holds the purchased assets , and repayable over a period of 21 -months

following a three-month grace period. Interest on the loan will be calculated at 12-month libor + 7.5%.

GSilver will also grant Ocean Partners 2,500,000 warrants on the same terms as offered to the purchasers of

subscription receipts in the proposed equity financing below. In conjunction with the OP Facility, the Company

has agreed to sell 100% of the concentrate produced from MMR’s Guanajuato mines including Valenciana and

San Ignacio to Ocean Partners for a minimum of 24 months, subject to minimum of 6,000 wet metric tonne s,

and 100% of all zinc concentrate produced from the Topia mine for the same period once Topia’s existing zinc

concentrate off-take agreement expires within the next month or so. The OP F acility is subject to customary

closing conditions including execution of definitive off-take pre-payment and security documentation, and TSXV

acceptance.

US$9.0M (C$11.55M) Equity Financing:

GSilver has received expressions of interest from insiders and “President’s List” investors for an equity financing

of approximately US$6.9M including a lead order from a n affiliate of Paris and Geneva based resource lender

OCIM. OCIM is currently GSilver’s senior lender, having advanced a US$7.5M debt facility in May, 2022.

GSilver has entered into an agreement with Research Capital Corporation and Canaccord Genuity Corp. as co-

lead agents and joint bookrunners, and on behalf of a syndicate of agents, including Echelon Wealth Partners

Inc. and Roth Capital Partners LLC (collectively the “Agents”), pursuant to which the Agents will undertake, on a

best-efforts basis, a “part -and-parcel” brokered private placement offering of 35,000,000 subscription

receipts of GSilver (the “Subscription Receipts”) at a price of C$0.33 (equivalent to approximately US$0.257) per

Subscription Receipt, to raise gross proceeds of up to C$11.55 million (equivalent to approximately US$9.0

million) (the “Equity Financing”). GSilver has also granted the Agents an option to increase the size of the Equity

Financing by up to an additional 15% of the Equity Financing or 5,250,000 Subscription Receipts (C$1,1732,500),

exercisable in whole or in part at any time up to 48 hours prior to closing of the Equity Financing.

4

The gross proceeds of the Equity Financing, less 50% of the Agents’ cash commission and expenses (see below),

will be deposited in escrow (the “ Escrowed Funds”) pending satisfaction of certain subscription receipt release

conditions (the “ SR Conditions ”) including the concurrent closing of the GP Agreement and receipt of all

necessary regulatory approvals including acceptance of the TSXV.

Upon closing of the GP Agreement, each Subscription Receipt will automatically convert , without payment of

any additional consideration or further action on the part of the holder thereof , into one unit of GSilver

consisting of one common share ( a “GSilver Share") and one common share purchase warrant (a " GSilver

Warrant") of GSilver and the Escrowed Funds and any accrued interest thereon (less the balance of the Agent’s

cash commission and expenses) will be released to the Company. Each GSilver Warrant will be exercisable for

one GSilver Share at a price of C$0.50 for a period of 36 months following closing of the GP Agreement. If the SR

Conditions are not satisfied within 90 days following closing of the Equity Financing (or such other date as the

Company and the Agents may agree), the Escrowed Funds and any interest accrued thereon will be returned to

the purchasers of Subscription Receipts and the Subscription Receipts will be cancelled.

In consideration for the ir services in connection with the Equity Financing, the Ag ents will receive a cash

commission of 6% of the gross proceeds raised , and brokers’ warrants (the “ Brokers’ Warrants”) of 6% of the

total number of Subscription Receipts sold, under the Equity Financing (subject to reduced cash commission and

Brokers’ Warrants on sales of Subscription Receipts to purchasers on the Company’s Presidents List). Each

Broker’s Warrant will entitle the holder thereof to purchase one GSilver Share for a period of 36 months

following closing of the GP Agreement at a price equal to the issue price of the Subscription Receipts. The Agents

will also be reimbursed for their reasonable expenses incurred in connection with the Equity Financing including

legal fees.

The net proceeds of the Equity Financing will be used to, among other things, finance the purchase price for the

MMR Acquisition, fund ongoing mining operations and for general corporate and working capital purposes.

The Equity Financing is scheduled to close on or about the week of July 27, 2022, or such other date as agreed

upon between the Company and the Agents and is subject to certain conditions including, but not limited to, the

receipt of all necessary approvals including the acceptance of the TSXV.

It is anticipated that certain directors, officers and other insiders of GSilver (collectively “ Insiders”) will

participate in the Equity Financing for up to a maximum of 10 % of the financing. S uch portion of the Equity

Financing with Insiders will constit ute a “related party transaction” for the purposes of Multilateral Instrument

61-101, Protection of Minority Security Holders in Special Transactions (“MI 61-101”), and GSilver intends to rely

upon exemptions from the requirement to obtain a formal valuation and seek minority shareholder approval for

the Equity Financing on the basis that the fair market value of the participation by such Insiders in the Equity

Financing will be less than 25% of GSilver’s current market capitalization. It is anticipated that the material

change report of GSilver to be filed in connection with this announcement of the MMR Acquisition, the OP

Financing and the Equity Financing will be filed less than 21 days in advance of the closing of the Equity

Financing, which GSilver considers reasonable within the context of current market conditions and to ensure

that the net proceeds of the Equity Financing are available to GSilver to fund the purchase price for MMR upon

closing of the GP Agreement.

All securities issuable in connection with the MMR Acquisition , the OP Facility and the Equity Financing will be

subject to a statutory hold period of 4 months and one day from the date of issue. In addition, Great Panther

has agreed to certain additional voluntary hold period s on 50% of the Consideration Shares to be release d in

stages up to 12 months following closing of the GP Agreement.

Assets Being Purchased:

Valenciana-Cata:

Under Great Panther, the mines situated near the centre of Guanajuato were known as t he “Guanajuato Mine

Complex” or “GMC”; s ituated along the highly productive Ve ta Madre (‘Mother Vein’). F rom north to south,

these mines are called Guanajuatito, Valenciana, Cata, Los Posos, and Promontorio . Henceforth, GSilver will

refer to these mines collectively as “Valenciana” and to the accompanying process ing plant , which has

nameplate capacity of 1200 tonnes per day, as “Cata”.

Mined since the 1500s, and encompassing a strike length of 4.2km, this mine became one of the premier silver

mines in the world and, for a time, accounted for up to one-third of global annual silver production.

Historical in-situ measured and indicated resources at Valenciana (GMC), as reported by Great Panther (effective

date: July 31, 2021) totalled 251,666 tonnes grading 250 gpt Ag and 1.76 gpt Au (400 gpt AgEq) for 3.23M AgEq

ounces, with inferred resources of 220,760 tonnes grading 225 gpt Ag and 1.95 gpt Au (391 gpt AgEq) for 2.77M

AgEq ounces. See the mineral resources table for Valenciana (GMC) under “Highlights” above. (2)

The Cata processing plant remains in good working condition and has a nameplate capacity of 1200 tonnes per

day (36,000 tonnes/month). The plant is a traditional crushing, grinding and floatation system that produces a

high-grade silver-gold concentrate.

Valenciana was put on care and maintenance by Great Panther in November 2021 because of a lack of tailings

space.

San Ignacio:

The San Ignacio Mine is located approximately 20km by road west of the city of Guanajuato and 38km from

GSilver’s El Cubo mill. Mineralization exists within an epithermal quartz vein system called ‘La Luz’, which is a

large regional tectonic structure that also hosts Endeavour Silver’s Bolanitos Mine.

San Ignacio has operated for 10 years, with high grade silver and gold material continually trucked to Great

Panther’s Cata mill for processing. GSilver intends to transport material from San Ignacio to El Cubo for

processing.

Historical in-situ measured and indicated resources at San Ignacio as reported by Great Panth er (effective date:

July 31, 2021) totalled 267,828 tonnes grading 145 gpt Ag and 2. 80 gpt Au ( 384 gpt AgEq) for 3.30M AgEq

ounces, with inferred resources of 445,217 tonnes grading 178 gpt Ag and 2.65 gpt Au (404 gpt AgEq) for 5.78M

AgEq ounces. See the mineral resources table for San Ignacio under “Highlights” above. (2)

San Ignacio was put on care and maintenance by Great Panther in January 2022 due to a lack of tailings capacity.

Topia Mine and Mill, Durango, Mexico.

Great Panther has operated the Topia Mine in north -eastern Durango since 2004 ; the mine includes a 260

tonnes per day flotation processing plant that is currently operating at close to full capacity. The mineral

deposits at Topia are different than t hose seen at Valenciana and San Ignacio , which exclusively produce

precious metals . Mineralization at Topia exists as polymetallic epithermal veins that contain high-grade

concentrations of silver, zinc, lead and gold. The Topia veins consist mainly of massive galena, sphalerite, and

tetrahedrite in a gangue of quartz, barite, and calcite.

6

Historical in -situ measured and indicated resources at Topia as reported by Great Panther (effective date:

March 31, 2021) total led 331,800 tonnes grading 609 gpt Ag, 1.84 gpt Au, 4.4%Pb and 4.5%Zn ( 1,041 gpt AgEq)

for 11.10M AgEq ounces, with inferred resources of 274 ,600 tonnes grading 592 gpt Ag, 1.44 gpt Au, 3.35% Pb

and 3.6 3%Zn (93 2 gpt AgEq) for 8.22M AgEq ounces. See the mineral resources table for Topia under

“Highlights” above. (2)

Topia is currently in operation ; the mine produces a lead -silver-gold concentrate an d a separate zinc

concentrate.

Closing of the MMR Acquisition is subject to a number of conditions including acceptance of the TSXV. There are

no assurances that the MMR Acquisition, the OP Facility and the Equity Financing will be completed on the

proposed terms or at all.

1 Extracted from Great Panther’s news release dated January 19, 2022. Silver equivalent ounces for 2021 were calculated

using an 85:1 Ag:Au ratio.

2 These estimates have been extracted from the following National Instrument 43-101 technical reports filed by Great

Panther under its profile on SEDAR at www.sedar.com and use the definitions of “Mineral Resource” set forth in the

CIM Definition Standards, adopted May 10, 2014, by the Canadian Institute of Mining, Metallurgy and Petroleum:

(a) NI 43-101 report on the Guanajuato Mine Complex dated February 28, 2022 (effective date July 31, 2021) prepared

on behalf of Great Panther by Robert F. Brown, P. Eng, and Mohammad Nourpour, P. Geo., (together the “ GP

Qualified Persons”) and titled “ NI 43-101 Mineral Resource Update Technical Report on the Guanajuato Mine

Complex, Guanajuato and San Ignacio Operations, Guanajuato State, Mexico” (the “Guanajuato Report”); and

(b) NI 43-101 report on the Topia Mine dated February 11, 2022 (effective date March 31, 2021) prepared on behalf of

Great Panther by the GP Qualified Persons and titled “ NI 43-101 Report on the Topia Mine Mineral Resource

Estimates as of March 31, 2021” (the “Topia Report”),

Such estimates are subject to certain assumptions regarding grade, metal prices, currency exchange rates, costs, metals

production rates, schedule of development, labour, consumables and other material costs, markets and market prices as

more particularly set out in the reports. AgEq oz were calculated using 85:1 Ag:Au ratio. AgEq gpt and AgEq oz figures

reported for Topia have been extracted from Great Panther’s news release dated February 11, 2022.

The G uanajuato resources were estimated from six area-specific block models at Guanajuato, and eighteen block models

at San Ignacio. A set of 44 wireframes representing the mineralized zones served to constrain the block models and data

8

subsequently used in Inverse Distance Cubed (ID3) Au and Ag grade interpolation. The geological interpretation was

provided by Great Panther. Wireframe modelling was completed using MICROMINE and Leapfrog 3D geological

modelling software and grade estimation and geological modelling completed using by MICROMINE software. See the

Guanajuato Report for further details of the key assumptions, parameters, and methods used to prepare the resource

estimate.

The Topia resources were estimated from 10 mine area-specific block models. A set of 60 wireframes representing the

mineralized zones (veins) served to constrain both the block models and data subsequently used in Inverse Distance

Cubed (ID3) gold, silver, lead, and zinc grade interpolations. Each block residing at least partly within one of 60

wireframes received a grade estimate. The full operational cost cut-off value as calculated by Great Panther’s mine

operating staff ranges from US$202 to US$345/tonne for different areas based on full mine operating costs (mining,

milling, administration). Block model silver, gold, lead, and zinc grades have been converted to an US$ NSR value using

an NSR “calculator” which takes into effect metal prices (long term projected to be US$20.00/oz silver, US$1,650/oz

gold, US$0.85/lb lead, and US$1.20/lb zinc), plant metallurgical recoveries of 92.4% for Ag, 55.4% for Au, 94.3% for

Pb, and 90.5% for Zn, concentrate shipping charges, and proprietary smelter terms. Blocks with an NSR value equal to or

greater than the operations full cut -off costs were tabulated into the m ineral resource estimate for each zone. The cut -off

value was applied to each block estimated in the resource block model. Mineral Resource blocks are only considered

Measured or Indicated if they are within 10m or 20m of underground channel sampling associated with mine

development. See the Topia Report for further details of the key assumptions, parameters, and methods use to prepare the

resource estimate.

GSilver is not treating th ese estimates as current mineral resources as a “qualified person” on behalf of GSilver has not

done sufficient work to classify the estimates as current mineral resources and therefore such estimates should not be

relied upon. A thorough review by GSilver’s “qualified person” of all historic data, along with additional exploration and

validation work to confirm results and estimation parameters, would be required in order to produce a current mineral

resource estimate for the Valenciana and San Ignacio mines and Topia.
