Exhibit 99.1

McEwen Generates Strong Q1 Results &
Advances Multi-Asset Growth Strategy
Net Income $33.4M ($0.56 per Share) vs. Net
Loss $6.3M ($0.12 per Share) in Q1 2025
Internally Funding Key Projects to Double Production
by 2030
TORONTO, May 6, 2026 - McEwen Inc. (NYSE/TSX:
MUX) (“McEwen” or the “Company”) today announced its first quarter financial results for the period ended
March 31, 2026 (Q1), along with an update on its development projects, including an updated Mineral Resource Estimate and strong
exploration results across all sites as the Company is advancing its plan to increase production to 250,000 - 300,000 GEOs by 2030.
Based on current gold and silver prices, McEwen
believes that if mine operations meet guidance, the Company can self-fund its future production growth with limited share dilution. This
will be a key driver behind growing our share price.
Strong Gold Prices Continue to Support Advancement
of Key Projects:
Canada
In Canada, McEwen is advancing growth projects
to increase production from 16,000 - 19,000 GEOs in 2026 to 105,000 - 120,000 GEOs by 2030. The
Company will be developing these projects in a phased approach that is focused on initial capital requirements, IRR and the ability
to execute successfully while prioritizing future growth through continued exploration success.
| · | Stock Mine (Fox Complex, Timmins, Ontario)
- Development continued on time and within budget during Q1. We invested $9.9 million into Stock during Q1 and $39.4 million since the
start of underground development last year. Stock is expected to begin initial production in H2 2026, with commercial production set for
2027. This is expected to result in lower-cost gold production at the Fox Complex compared to current operations, due to a lower
royalty burden, shorter haulage distances to the mill, and the benefits of processing softer material. Based on the current Mineral
Resource Estimate, McEwen projects a six-year life at Stock, which is expected to increase as underground drilling advances to enhance
resources throughout coming years. |
| · | Grey Fox (Fox Complex, Timmins, Ontario) -
Work is now being finalized on the Pre-Feasibility Study (“PFS”) that will be released in the coming months. The PFS will
highlight the Company’s ability to materially extend mine life at the Fox Complex, while using existing infrastructure. McEwen is
targeting combined annual production from Grey Fox and Stock of 75,000 - 90,000 GEOs by 2030. |
| · | Tartan Mine Project (Flin Flon, Manitoba)- During Q1 the Company delivered a Mineral Resource Estimate with underground Indicated Resources totalling 308,900 gold
ounces (2,619,000 tonnes at 3.67 gpt Au) and Inferred Resources totalling 302,700 gold ounces (2,832,900 tonnes at 3.32
gpt Au). The Company is reviewing existing environmental licenses, planning additional metallurgical testing, beginning underground mine
designs, and potential equipment purchases as part of its plan to restart production within the existing permits. McEwen expects initial
annual production at Tartan to average approximately 30,000 GEOs, with the potential to expand output through future permit
modifications. The Company believes doubling the throughput from 500 tonnes per day (tpd) to 1,000 tpd could see production grow
to 45,000 - 55,000 GEOs per year. |

USA
In Nevada, McEwen is forecasting that production
will more than double from 39,000 - 43,000 GEOs in 2026 to 90,000 - 110,000 GEOs by 2030, driven by production from Lookout
Mountain, Windfall and Trinity Ridge. All three deposits are located within the Gold Bar Mine Complex and management will look to leverage
the current infrastructure at site.
| · | Windfall, Lookout Mountain and Trinity Ridge
(Gold Bar Mine Complex) - Gold Bar’s transformation into a long-life mine with increased production reached another milestone
with the publication of the Windfall Mineral Resource Estimate. Windfall shows open-pit Indicated Resources of 227,500 gold
ounces (9,402,800 tonnes at 0.75 gpt Au) and Inferred Resources of 127,800 gold ounces (2,596,400 tonnes at 1.53
gpt Au). Currently, 100% of the Mineral Resource Estimate is oxide gold mineralization that could potentially be processed
using the same heap leaching methods being used at the Gold Bar Mine. |
|
|
The global Resources and Reserves for the Gold Bar Mine Complex are the combined Mineral Resources and Reserves for Gold Bar Mine, Lookout
Mountain and Windfall, which now total Indicated Resources of 792,000 gold ounces (38,602,800 tonnes @ 0.64 gpt Au) and
Inferred Resources of 281,000 gold ounces (11,256,200 tonnes @ 0.78 gpt Au). This is in addition to Probable Reserves
of 168,000 gold ounces (8,624,000 tonnes at 0.61 gpt Au). |
|
|
Trinity Ridge is the next deposit where a Mineral Resource Estimate is set to be published within the Gold Bar Mine Complex and
will look at merging the smaller existing Gold Bar Mine open pits into one enlarged pit that will capture a meaningful amount of gold
mineralization that has not been included in the current Mineral Resource Estimate. Currently, 60% of the planned drilling at Trinity
Ridge has been completed and a Mineral Resource update is expected by early 2027. |
| · | McEwen has completed its acquisition of Golden
Lake Resources Inc. Golden Lake’s Jewel Ridge and Jewel Ridge West projects adjoin McEwen’s Windfall deposit to the north
and have encouraging historical drill results, which highlight the potential to further grow our resources at the Gold Bar Mine Complex
and to increase mine life. |
Mexico
In Mexico, McEwen is forecasting 20,000 GEOs
production per year starting mid-2027.
| · | El Gallo - The Company continues to target
Phase 1 production starting mid-2027. Detailed engineering is well advanced, with construction of the mill expected to begin in early
Q3. Phase 1 is expected to operate for at least 10 years, producing approximately 20,000 GEOs annually once commercial production
is achieved. The Company is exploring opportunities within its land package that would require minimal capital to see the life of Phase
1 extended. Permit approval for Phase 2 (El Gallo Silver) would materially extend the mine life and increase production to approximately
40,000 - 50,000 GEOs (based on 77:1 silver to gold ratio) due to higher grades being processed. The Company is currently updating
the Mineral Resource Estimate to include all resources around the proposed mill site, which will be released in Q3. |

Argentina
| · | San José Mine - The operation is
benefiting from the recently completed process plant expansion and higher mining rates, resulting in increased production and lower costs.
At current gold and silver prices, San José is expected to be an important source of capital that the Company will use to expand
production at its other sites. Production attributable to McEwen’s 49% interest is targeted at 60,000 - 70,000 GEOs per year
(based on a 77:1 silver-to-gold ratio). The Company anticipates receiving $40 - $50M from San José in 2026. |
|
|
McEwen owns a 46.3% equity stake in McEwen Copper and a 1.25% NSR royalty on McEwen Copper’s Los Azules copper project. The royalty
is projected to generate pre-tax $520.5 million at recent copper spot price of $5.80/lb and $389.5 million at the feasibility
study's base-case copper price of $4.35/lb over the 22-year mine life. There is potential to extend the life of Los Azules by an additional
33 years. |
|
|
Los Azules advanced significantly in 2025, completing two foundational milestones: approval of its application under Argentina’s
RIGI (Large Investment Incentive Regime), securing 30 years of legal, fiscal, and customs stability; and publication of a Feasibility
Study confirming robust project economics, with initial 5-year average production of 205 ktpa of copper cathodes at $1.71/lb C1 cash
cost over a 22-year mine life and identified upside potential to extend mine life for an additional 33 years adding an average of 141ktpa
Cu per annum. |
|
|
Following the Feasibility Study, project costs began to be capitalized in late Q3 2025 under U.S. GAAP. The 2026 objective is to advance
the project toward a Final Investment Decision targeted for year-end 2026, with construction targeted to commence in early 2027, and
production in 2030, subject to project financing and customary approvals. |
Highlights of Q1
2026
Abbreviations used are defined in the Glossary
at the end of this press release.
| Revenue |
Q1 2026 revenue increased by 107% to $74.0M from the sale of 15,752 GEOs, vs revenue of $35.7M from the sale of 13,036 GEOs in Q1 2025. The average realized gold sale price per GEO was $4,792 in Q1, 71% higher than $2,803 in Q1 2025. Our 49% ownership in the San José mine is excluded from our revenue numbers due to accounting policies under U.S. GAAP. |
| |
|
| Profitability |
Q1 2026 gross profit was $31.5M, compared with $10.1M in Q1 2025. Gross margins were positively impacted by increased production and higher gold prices. Q1 2026 net income was $33.4M or $0.56 per share, compared with a net loss of $6.3M or $0.12 per share in Q1 2025. |
| |
|
| Adjusted EBITDA |
Q1 2026 adjusted EBITDA increased to $44.8M
or $0.76 per share, compared with $8.7M or $0.16 per share in Q1 2025.
Adjusted EBITDA is calculated by adding back
our portion of McEwen Copper's results to our consolidated income or loss before financing costs, depreciation, and income and mining
taxes. We use adjusted EBITDA to evaluate our operating performance and ability to generate cash flow from our gold operations in production,
including the San José Mine. |

|
Liquidity & Capital Resources at March 31, 2026
|
Cash and equivalents increased to $56.5M,
compared with $51.0M at December 31, 2025.
The value of marketable securities decreased to
$13.5M, compared with $21.1M at December 31, 2025. The main reason for the decrease is due to McEwen having acquired 100%
of Canadian Gold Corp., which had a market value of $5.6M at December 31, 2025.
On December 9, 2025, the Company acquired
a 27.3% interest in Paragon Advanced Labs, at a cost basis of $13.7M. As of March 31, 2026, the fair value of the
investment was $20.4M.
As of March 31, 2026, McEwen has loaned $13.6M
to McEwen Copper.
The most recent financing of McEwen Copper at
$30 per share on October 24, 2024 implies a full market value of $987.5M. Based on this valuation, McEwen’s 46.3%
ownership of McEwen Copper has an implied market value of $457M or $7.65 per MUX share (based on McEwen’s shares outstanding
as of the date of this press release). Since that financing, the project has seen significant development and derisking with the RIGI
approval, the completion of the feasibility study, and is now preparing for a Final Investment Decision.
Debt principal outstanding remained unchanged
at $130.0M ($110.0M in convertible notes due 2030 and $20.0M under our term loan facility). The reported total debt of $126.4M
reflects the debt principal of $130.0M, less debt issuance costs of $3.6M, which are amortized over the life of the debt, in accordance
with U.S. GAAP.
McEwen had 59.2M shares outstanding on March 31,
2026, compared with 55.5M shares on December 31, 2025, mainly due to the shares issued in connection with the acquisition of Canadian
Gold Corp. |

|
|
San José Mine Performance
|
14,582 GEOs were produced in Q1 and were
33% higher than in Q1 2025. Strong production continued from Q4 2025 and was the result of increased plant capacity and mining rates.
Given the strong production in Q1, production
costs per GEO sold were $2,365 for cash costs and $2,704 for AISC, a decrease of 8% and 11%, respectively, compared with
Q1 2025.
In February, McEwen received an $8.8 M
dividend from the San José Mine. Gowing forward, San José intends to pay out 90% of the mine’s cash flow to the partners.
At March 31, 2026, the San José
Mine held a cash balance of $217.1M versus $151.8M on December 31, 2025, on a 100% basis. At current gold and silver prices, the
Company anticipates receiving $40-$50M in dividend payments from San José in 2026. |

| Gold Bar Performance |
7,884 GEOs were produced from the Gold
Bar Complex in Q1. Costs were higher than Q1 2025 due to 1) lower mined grades, and 2) increased mining of non-mineralized material.
Both factors were anticipated and incorporated into our 2026 planning, and Gold Bar is on track to meet 2026 production and cost
guidance.
Costs per GEO sold in Q1 were $2,460 for
cash costs and $2,705 for AISC.
|
| Fox Complex Performance |
5,784 GEOs were produced in Q1. Costs per GEO sold in Q1 were $2,365 for cash costs and $3,148 for AISC. AISC costs were higher compared to prior quarters due to development work completed on the lower levels of Froome West to create access to new mining areas later in the year. This accounted for $778 of the AISC per ounce during the quarter. These costs are expected to trend down through 2026 as required development is completed.
|
| Exploration & Development |
$5.5M was invested during Q1 in exploration,
compared with $3.7M in Q1 2025. For the full year, the Company is planning to invest $22.2M across its portfolio. Recent exploration
highlights are detailed in their respective sections in this news release.
$16.5M was invested by McEwen Copper in
the Los Azules copper project in Q1, representing our 46.3% share of costs to advance detailed engineering in preparation of a
final investment decision, compared with $18.5M in Q1 2025. As a Mineral Reserve statement with an effective date of September 3,
2025 was published, eligible development costs are now capitalized and will no longer be included in McEwen’s income statement
under U.S. GAAP.
|
| Health & Safety |
On April 3, a contractor working for McEwen
Copper at the Los Azules project in Argentina died during road construction when their bulldozer overturned. A full investigation at Los Azules
is underway. A second fatality occurred on April 6, at the Gold Bar Mine, where a contractor passed away due to natural causes.
The Company is deeply saddened by these events
and extends sincere condolences to the families, friends and colleagues affected by these losses.
|
| 2026 Production & Unit Costs Outlook |
Full-year 2026 production guidance remains between
114,000 - 126,000 GEOs, including our attributable production from our 49%-owned San José mine and assuming a 77:1 silver-to-gold
ratio. Our production guidance does not include early pre-commercial production from the Stock mine.
Cost per ounce guidance range remains unchanged,
at $2,100 to $2,300 for cash costs, and $2,400 to $2,600 for AISC. |

Mineral Resource &
Exploration Update
Gold Bar Mine Complex, Nevada (100% owned)
Update to Mineral Resource Estimate at Gold
Bar
The Company is advancing three key areas at its
Gold Bar Mine Complex to increase resources, extend mine life and boost annual production: 1) Lookout Mountain, 2) Windfall, and 3) Trinity
Ridge, which envisions merging and enlarging several of the current open pits to access gold mineralization outside the current mine plan.
McEwen believes that integrating these areas has the potential to transform the Gold Bar Mine Complex into a long-life asset. The Company
released a Mineral Resource Estimate for Lookout Mountain with the 2025 year-end financial statements and is now pleased to release a
Mineral Resource Estimate for the Windfall deposit located approximately 3 miles (5 km) NE of Lookout Mountain. The Windfall MRE is shown
below:

A Mineral
Resource Estimate for Trinity Ridge will be completed separately and released early 2027. Notably, Trinity Ridge lies within the current
Plan of Operations for mining activities at the Gold Bar Mine Complex and Windfall is located on private land, which should allow for
an accelerated permitting process.
Exploration at Gold Bar
Over the
past nine months, drilling at the northern end of the Windfall deposit has been returning good gold grades over long widths. The results
highlighted below were received after the effective cut-off date for the Windfall Mineral Resource Estimate. It is also important to note
that the results from Windfall continue to show oxide mineralization that could potentially be processed using the same heap leaching
technology currently used at the Gold Bar Mine, with McEwen looking to utilize the existing mine infrastructure where possible. Our focus
is on return on capital and how efficiently these new ounces can be developed and produced.

Trinity Ridge
At Trinity Ridge, located within the current limits
of Gold Bar Mine, the Company is at the early stages of evaluating the potential to expand and merge three existing open pits into one
larger pit.
Recent drill results continue to support the Company’s
development plans for the area, with highlights shown below:
| - | 1.2 gpt gold over 18.3 meters (RCW) in drillhole PK 105 |
| - | 1.1 gpt gold over 15.2 meters (RCW) in drillhole PK 107 |
| - | 1.0 gpt gold over 35.1 meters (RCW) in drillhole PK 110 |
| - | 1.9 gpt gold over 41.1 meters (RCW) in drillhole PK 115 |
| - | 1.7 gpt gold over 21.3 meters (RCW) in drillhole RG053 |

Fox Complex Mine, Ontario (100% owned)
Exploration at Grey Fox (Fig.
3, Fig. 4 and Fig. 5)
Early in 2026, drilling at Grey Fox focused on
the Gibson and Whiskey Jack Zones, where the team at McEwen believes mining can be accelerated due
to their location near existing underground infrastructure.
These new
drill results support additional resource growth beyond the pending PFS:
| - | 6.1 gpt gold over 7.3 meters (TW) in drillhole 25GF-1675 |
(Infill hole that has demonstrated good
continuity with higher grades)
| - | 5.3 gpt gold over 7.3 meters (TW) in drillhole 25GF-1611 |
(Expansion zone hole located 135 meters
north of the Gibson Zone)
| - | 254.2 gpt gold over 0.8 meters (TW)
in drillhole 25GF-1655 |
(Located 180 meters from existing Gibson
Ramp infrastructure and remains open for expansion)
| - | 11.9 gpt gold over 5.7 meters (TW)
in drillhole 26GF-1698 |
(Expanded the zone by 85 meters vertically
or by 30% and remains open for expansion)

Fig. 4. Whiskey Jack Cross Section

In 2025, McEwen also completed a 6,500-meter drill
program at the Stroud deposit that was acquired in 2024. Stroud is located 1,500-meters southwest of the current Grey Fox Mineral Resource
area (Fig. 5). The drill program was designed to confirm the historical drilling in order to update the Mineral Resource Estimate, which
is set to be released with the Grey Fox PFS.
Drill highlights are shown below:
| - | 12.6 gpt gold over 5.9 meters

Tartan Mine Project, Manitoba (100% Owned)
Exploration at Tartan (Fig. 6)
On March 23, 2026, the Company released a
Mineral Resource Estimate for the Tartan Mine Project that will serve as the foundation for a potential restart of the mine. The underground
Mineral Resource Estimate outlined 308,900 gold ounces Indicated (2,619,000 tonnes @ 3.67 gpt gold) and 302,700 gold ounces
Inferred (2,832,900 tonnes @ 3.32 gpt gold) with the mineralization open for expansion. New drill results that have been received after
the effective cut-off date for the Mineral Resource Estimate highlight further growth potential and are shown below (Fig. 6):

Notes to Table 3:
| 1. | Cash gross profit, cash costs per ounce, and all-in sustaining costs (AISC) per ounce, adjusted
earnings before interest, taxes, depreciation, and amortization (adjusted EBITDA) and adjusted EBITDA per share are non-GAAP
financial performance measures with no standardized definition under U.S. GAAP. For definitions of these non-GAAP measures, refer to the
“Non-GAAP Financial Measures” section in this press release. For reconciliations to the closest U.S. GAAP measures, see the
Management Discussion and Analysis for the quarter ended March 31, 2026, filed on EDGAR and SEDAR Plus. |
| 2. | Gold Equivalent Ounces (GEOs) are calculated using gold-to-silver price ratio of 58:1
for Q1 2026 and 90:1 for Q1 2025. 2026 production guidance is calculated based on 77:1 gold to silver price ratio. |
| 3. | El Gallo contributed 2,220 GEOs of production in Q1 2026. |
| 4. | San José Mine figures represent the portion attributable to McEwen from its 49%
interest in the San José Mine. |

CAUTIONARY NOTE
REGARDING NON-GAAP MEASURES
We have included in this report certain non-GAAP
performance measures as detailed below. In the gold mining industry, these are common performance measures but do not have any standardized
meaning and are considered non-GAAP measures. We use these measures to evaluate our business on an ongoing basis and believe that, in
addition to conventional measures prepared in accordance with GAAP, certain investors use such non-GAAP measures to evaluate our performance
and ability to generate cash flow. We also report these measures to provide investors and analysts with useful information about our underlying
costs of operations and clarity over our ability to finance operations. Accordingly, they are intended to provide additional information
and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. There are limitations
associated with the use of such non-GAAP measures. We compensate for these limitations by relying primarily on our U.S. GAAP results and
using the non-GAAP measures supplementally.
The non-GAAP measures are presented for our wholly
owned mines and our interest in the San José mine. The amounts in the reconciliation tables labeled “49% basis” were
derived by applying to each financial statement line item the ownership percentage interest used to arrive at our share of net income
or loss during the period when applying the equity method of accounting. We do not control the interest in or operations of MSC and the
presentations of assets and liabilities and revenues and expenses of MSC do not represent our legal claim to such items. The amount of
cash we receive is based upon specific provisions of the Option and Joint Venture Agreement (“OJVA”) and varies depending
on factors including the profitability of the operations.
The presentation of these measures, including
the minority interest in the San José, has limitations as an analytical tool. Some of these limitations include:
| · | The amounts shown on the individual line items
were derived by applying our overall economic ownership interest percentage determined when applying the equity method of accounting and
do not represent our legal claim to the assets and liabilities, or the revenues and expenses; and |
| · | Other companies in our industry may calculate
their cash costs, cash cost per ounce, all-in sustaining costs, all-in sustaining costs per ounce, adjusted EBITDA, and average realized
price per ounce differently than we do, limiting the usefulness as a comparative measure. |
Cash Costs and All-In Sustaining Costs
The terms cash costs, cash cost per ounce, all-in
sustaining costs (“AISC”), and all-in sustaining cost per ounce used in this report are non-GAAP financial measures. We report
these measures to provide additional information regarding operational efficiencies on an individual mine basis, and believe these measures
provide investors and analysts with useful information about our underlying costs of operations.
Cash costs consist of mining, processing, on-site
general and administrative expenses, community and permitting costs related to current operations, royalty costs, refining and treatment
charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs, but exclude depreciation
and amortization (non-cash items). The sum of these costs is divided by the corresponding gold equivalent ounces sold to
determine a per ounce amount.
All-in sustaining costs consist of cash costs
(as described above), plus accretion of retirement obligations and amortization of the asset retirement costs related to operating sites,
environmental rehabilitation costs for mines with no reserves, sustaining exploration and development costs, sustaining capital expenditures
and sustaining lease payments. Our all-in sustaining costs exclude the allocation of corporate general and administrative costs. The following
is additional information regarding our all-in sustaining costs:
| · | Sustaining operating costs represent expenditures
incurred at current operations that are considered necessary to maintain current annual production at the mine site and include mine development
costs and ongoing replacement of mine equipment and other capital facilities. Sustaining capital costs do not include costs of expanding
the project that would result in improved productivity of the existing asset, increased existing capacity or extended useful life. |
| · | Sustaining exploration and development costs
include expenditures incurred to sustain current operations and to replace reserves and/or resources extracted as part of the ongoing
production. Exploration activities performed near-mine (brownfield) or new exploration projects (greenfield) are classified as non-sustaining. |
The sum of all-in sustaining costs is divided
by the corresponding gold equivalent ounces sold to determine a per ounce amount.
Costs excluded from cash costs and all-in sustaining
costs, in addition to depreciation and depletion, are income and mining tax expenses, all corporate financing charges, costs related to
business combinations, asset acquisitions and asset disposal, and any items that are deducted for the purpose of normalizing items.

The following tables reconcile these non-GAAP
measures to the most directly comparable GAAP measure, production costs applicable to sales:
