Significant increase in mineral resources
at two principal assets
TORONTO, March 30,
2023 /CNW/ - Argonaut Gold Inc. (TSX: AR) (the
"Company", "Argonaut Gold" or "Argonaut"), is pleased to announce
today a significant increase in Mineral Resources for the Company's
two principal assets: the Magino Project, in the final stages of
construction, located in Ontario,
Canada, and the Florida Canyon Mine located in Nevada, USA. Measured and Indicated
Mineral Resources at the Company's two principal assets increased
by 14% to 5.7 million gold ounces, while Inferred Mineral Resources
more than quadrupled to 3.0 million gold ounces. On a consolidated
basis, Measured and Indicated Mineral Resources total 11.3 million
gold ounces, Inferred Mineral Resources total 3.5 million gold
ounces, and Proven and Probable Mineral Reserves total 5.6 million
gold ounces effective December 31,
2022.
"This updated resource statement underpins our belief that the
combination of Magino and a redevelopment of Florida Canyon can
provide the foundation for Argonaut's transition into a low-cost
mid-tier gold producer in North
America," stated Richard
Young, President and Chief Executive Officer.

The M&I Mineral
Resources and Inferred Mineral Resources for the Cerro del Gallo
Project set out in the table above were taken from the
technical report titled "Pre-Feasibility Study NI 43-101
Technical Report Cerro del Gallo Heap Leach Project Guanajuato,
Mexico", dated January 31, 2020 (effective date of October 24, 2019
(the "Cerro del Gallo Technical Report"). The
Mineral Resources were estimated at a gold price of $1,600 per
ounce and a silver price of $20.00 per ounce. Cut-off grades range
from 0.25 g/t AuEQ to 0.30 g/t AuEQ depending on ore
type.
|
(12)
|
The M&I Mineral
Resources and Inferred Mineral Resources for the San Antonio
Project set out in the table above were taken from the technical
report titled "NI 43-101 Technical Report on Resources, San Antonio
Project", dated October 10, 2012 (effective date of September 1,
2012), prepared by Leah Mach, M.Sc. Geology, CPG and Mark Willow,
M.Sc., C.E.M. of SRK Consulting (U.S.) Inc., Richard Rhoades, P.E.,
and Carl Defilippi, M.Sc. C.E.M., SME of Kappes Cassiday &
Associates (the "San Antonio Technical Report"). The
Mineral Resources were estimated at a gold price of $1,500 per
ounce using a cut-off grade of 0.11 g/t Au for oxide and transition
and 0.15 g/t Au for sulphide. On December 5, 2022, Argonaut entered
into an Option Agreement whereby Heliostar Metals Limited has been
granted the option to acquire a 100% interest in and to San
Antonio.
|
(13)
|
The Company
completed the sale of the Ana Paula Project to Heliostar Metals
Limited in March 2023 as per the purchase agreement, therefore
Mineral Resource and Reserve estimates prepared for this property
are not included in these tables.
|
Magino Project
At Magino, nearly all of the Measured, Indicated and Inferred
Mineral resources fall into a larger open pit cone, as the deeper
high-grade drill results from the 2022 exploration program
targeting underground potential ended up floating into a deeper
open pit cone. Magino's Mineral Reserve estimate remains
largely unchanged from the prior year at 2.4 million gold ounces.
Prior year reserves were estimated using a long-term gold price of
$1,600 per ounce, while this year the
Company is reporting Mineral Reserves using $1,350 per ounce, removing 66,000 ounces of
low-grade material from reserves as a result.
"Magino is a large high-quality asset with significant growth
and expansion potential. This year, we expect to begin a program to
convert resources to reserves within the open pit, and target the
high-grade potential at depth," stated Marc
Leduc, Chief Operating Officer. "We believe Magino will grow
in size and quality to become Argonaut's cornerstone asset and one
of the largest, lowest-cost gold mines in Canada."
Magino is expected to achieve commercial production in the third
quarter of 2023.
Florida Canyon Mine
At Florida Canyon, Inferred Mineral Resources increased to 2.1
million gold ounces from 20,000 gold ounces last year, in part due
to the inclusion of 28,956 metres of drilling, and initial
inclusion of sulfide mineralization. The inclusion of 700,000
ounces of sulfide mineralization helped pull an additional 1.35
million ounces of oxide mineralization into a large economic pit.
The Mineral Reserve estimate for Florida Canyon remains largely
unchanged at 930,000 gold ounces, as additional drilling offset
depletion and loss from higher costs.
"Our Florida Canyon mine has significant growth potential as it
resembles many gold deposits in Nevada where large sulfide deposits exist
below oxide mineralization. Florida Canyon has produced 2.8 million
ounces of gold since it opened in 1986, demonstrating a geological
system that created significant gold mineralization. Last year, we
drilled FCM-0124 that had a mineralized interval of 73 metres at
8.8 grams per tonne gold, which demonstrates the high-grade nature
in some of the sulfide zones. The focus this year will be on
updating the geologic model for the property and beginning a
proof-of-concept drilling program on the sulfides to demonstrate
the growth opportunity of this asset," added Mr. Leduc.
La Colorada Complex
At La Colorada Complex, the Mineral Reserve Estimate increased
by 13% to 512,000 gold ounces based on 14,450 metres of drilling,
which added 115,000 ounces or 56,000 ounces net of depletion, with
approximately 75% contained within the El Creston pit. Measured and
Indicated Resources decreased due to the removal of the Gran
Central deposit from the resource model. The deep drilling at
El Creston had a significant positive impact on the overall grade
of the La Colorada Complex, which increased more than 20% to 0.83
grams per tonne as higher-grade material was encountered at
depth.
San Agustin Mine
At San Agustin, both Mineral
Reserves and Resource estimates declined materially. Reserves
declined by 57% to 145,000 gold ounces from 336,000 gold ounces.
Measured and Indicated Resources and Inferred resources declined by
approximately 60% and 70%, respectively. The decline in reserves
and resources was largely due to depletion, the impact of a higher
cost structure, and modeling changes.

Cautionary Note on Mineral
Resource and Reserve Estimates
The Mineral Resources and Mineral Reserves tables above are as
at December 31, 2022. Mineral
Resources are not Mineral Reserves and do not have demonstrated
economic viability. Mineral Resources hold intrinsic economic
interest, which has been identified and estimated through
exploration and sampling and within which Mineral Reserves may
subsequently be defined. There is no certainty that all or any part
of the Mineral Resources will be converted into Mineral Reserves.
Measured and Indicated Mineral Resources listed above are inclusive
of Mineral Reserves.
Cautionary Note Regarding
Forward-looking Statements
This press release contains certain "forward-looking statements"
and "forward-looking information" under applicable Canadian
securities laws concerning the business, operations and financial
performance and condition of Argonaut Gold. Forward-looking
statements and forward-looking information include, but are not
limited to statements with respect to: the availability and change
in terms of financing, the Magino construction capital estimate;
the ability to finance additional construction costs on terms
acceptable to Argonaut; risks related to meeting the Magino
construction project schedule; the realization of mineral reserve
estimates; the timing and amount of estimated future production;
the impact of inflation on costs of exploration, development and
production; estimated production and mine life of the various
mineral projects of Argonaut; risk of employee and/or contractor
strike actions; timing of approval for modifications to existing
permits; permitting and legal processes in relation to mining
permitting and approval; the benefits of the development potential
of the properties of Argonaut; the future price of gold, copper,
and silver; the estimation of mineral reserves and resources;
success of exploration activities;; and currency exchange rate
fluctuations. Except for statements of historical fact relating to
Argonaut, certain information contained herein constitutes
forward-looking statements. Forward-looking statements are
frequently characterized by words such as "plan," "expect,"
"project," "intend," "believe," "anticipate", "estimate" and other
similar words, or statements that certain events or conditions
"may", "should" or "will" occur. Forward-looking statements are
based on the opinions and estimates of management at the date the
statements are made, and are based on a number of assumptions and
subject to a variety of risks and uncertainties and other factors
that could cause actual events or results to differ materially from
those projected in the forward-looking statements. Many of these
assumptions are based on factors and events that are not within the
control of Argonaut and while Argonaut believes that the
assumptions reflected in those forward-looking statements are
reasonable, there is no assurance they will prove to be correct.
Argonaut cautions that the foregoing list of important factors is
not exhaustive. Investors and others who base themselves on
forward-looking statements should carefully consider the above
factors as well as the uncertainties they represent and the risk
they entail. Argonaut believes that the expectations reflected in
those forward-looking statements are reasonable, but no assurance
can be given that these expectations will prove to be correct.
These factors are discussed in greater detail in Argonaut's most
recent Annual Information Form dated March
31, 2023 (the "AIF") and in the most recent Management's
Discussion and Analysis filed on SEDAR, which also provide
additional general assumptions in connection with these statements.
We encourage all investors to review the Risk Factors section
of our AIF in detail prior to making an investment decision in
Argonaut.
Although Argonaut has attempted to identify important factors
that could cause actual actions, events or results to differ
materially from those described in forward-looking statements,
there may be other factors that cause actions, events or results
not to be anticipated, estimated or intended. There can be no
assurance that forward-looking statements will prove to be
accurate, as actual results and future events could differ
materially from those anticipated in such statements. Argonaut
undertakes no obligation to update forward-looking statements if
circumstances or management's estimates or opinions should change
except as required by applicable securities laws. The reader is
cautioned not to place undue reliance on forward-looking
statements. Statements concerning mineral reserve and resource
estimates may also be deemed to constitute forward-looking
statements to the extent they involve estimates of the
mineralization that will be encountered if the property is
developed. Comparative market information is as of a date prior to
the date of this document.
