Darren Hall, President and Chief Executive Officer of Calibre, stated: “Calibre delivered a record Q4 consolidated gold production of 76,269 ounces, and full year 2024 production of 242,487 ounces, surpassing the revised 2024 annual production guidance. As of February 15, 2025, the year is off to a strong start with consolidated production trending 15% higher than budget and cash increased to $161 million, a 23% increase over December 31, 2024.

2025 is set to be a transformative year for Calibre, with the Valentine Gold Mine on track for first gold during the second quarter. We hired a high quality, experienced operating team through 2024 and are working with Reliable Controls Corporation to conduct pre-commissioning and commissioning to ensure operational readiness. In addition, all necessary equipment and resources for timely production are on site. Based on the 2022 Feasibility Study*, Valentine’s life-of-mine average production is expected to be approximately 195,000 ounces per year, with the process plant expected to reach 2.5 Mpta by the end of 2025.

Article content

The exploration potential at Valentine is incredibly exciting. We have seen continued success since the discovery made southwest of the Leprechaun deposit in late 2024 with initial drill results returning grades more than 40% above Mineral Reserve grade. As we progress during 2025, we are preparing for the largest pure exploration program in Valentine’s history. With tens of kilometres of the Valentine Lake Shear Zone and the Parallel Northwest Contact still untested, we remain optimistic about the significant upside potential as we advance efforts to establish this district as a new gold camp.

With strong gold prices, consistent operating performance, successful exploration results and Valentine on track to enhance diversification and growth, I am confident that we will continue delivering superior value for our shareholders.”

2025 GUIDANCE

Article content

The 2025 guidance currently covers gold production, TCC, AISC, and growth capital for operations in Nicaragua and Nevada. The consolidated exploration guidance includes drilling activities at the Valentine gold mine. Guidance for Valentine, including production, TCC, AISC, growth and full-year consolidated details, will be provided after first gold is produced from Valentine, expected during Q2 this year.

Calibre is nearing completion of construction at its Valentine Gold Mine in Newfoundland & Labrador, which is set to become Atlantic Canada’s largest gold mine. This milestone marks a significant transformation for the Company from a junior gold miner to a diversified, mid-tier gold producer.

Calibre will continue to reinvest in exploration and growth, with approximately 200,000 metres of drilling planned and the development of new satellite deposits across its asset portfolio.

Exploration activities in 2025 include multi-rig diamond, RC and RAB drilling in Newfoundland, Nevada and Nicaragua alongside several geoscience initiatives. Growth capital investments include underground and open pit mine development, waste stripping and strategic land acquisitions.

Notes

* Refer to the “Valentine Gold Project NI 43-101 Technical Report and Feasibility Study, Newfoundland & Labrador, Canada” dated November 30, 2022 and found on the Calibre website at www.calibremining.com and on SEDAR+ at www.sedarplus.ca.

(1) NON-IFRS
FINANCIAL
MEASURES

Calibre has included certain non-IFRS measures as discussed below. The Company believes that these measures, in addition to conventional measures prepared in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. These non-IFRS measures 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
IFRS.
These measures
do
not
have
any
standardized
meaning
prescribed
under
IFRS,
and
therefore may not be comparable to other issuers.

TCC per Ounce of Gold: TCC include production costs, royalties, production taxes, refinery charges, and transportation charges. Production costs consist of mine site operating costs such as mining, processing, local administrative costs (including stock-based compensation related to mine operations) and current inventory write-downs, if any. Production costs are exclusive of depreciation and depletion, reclamation, capital and exploration costs. TCC are net of by-product silver sales and are divided by gold ounces sold to arrive at a per ounce figure.

Article content

AISC per Ounce of Gold:
AISC is a performance measure that reflects the total expenditures that are required to produce an ounce of gold from current operations. While there is no standardized meaning of the measure across the industry, the Company’s definition is derived from the definition as set out by the World Gold Council in its guidance dated June 27, 2013, and November 16, 2018, respectively. The World Gold
Council
is
a
non-regulatory,
non-profit
organization
established
in
1987
whose
members
include
global senior mining companies. The Company believes that this measure is useful to external users in assessing operating performance and the ability to generate free cash flow from operations.

Calibre
defines
AISC
as
the
sum
of
TCC,
corporate
general
and
administrative
expenses
(excluding
one-time charges), reclamation accretion related to current operations and amortization of asset retirement obligations (“ARO”), sustaining capital (capital required to maintain current operations at existing production levels), lease repayments, and exploration expenditures designed to increase resource confidence at
producing mines. AISC
excludes
capital
expenditures
for significant improvements
at existing operations deemed to be expansionary in nature, exploration and evaluation related to resource growth, rehabilitation
accretion
not
related
to
current
operations,
financing
costs,
debt
repayments,
and
taxes.
Total AISC is divided by gold ounces sold to arrive at a per ounce figure

Article content

Average Realized Price per Ounce Sold:
Average Realized Gold Price Per Ounce Sold is intended to enable management
to
understand
the
average
realized
price
of
gold
sold
in
each
reporting
period
after
removing the impact of non-gold revenues and by-produce credits, which in the Company’s case are not significant, and to
enable
investors
to understand the Company’s
financial performance based
on
the average realized proceeds
of
selling
gold
production
in
the
reporting
period.
Average
Realized
Gold
Price
Per
Ounce
Sold
is
a common performance measure that does not have any standardized meaning.
The most directly comparable measure prepared in accordance with IFRS is revenue from gold sales.

Adjusted
Net
Earnings:
Adjusted
Net
Earnings
and
Adjusted
Net
Earnings
Per
Share
–
Basic
exclude
a
number of temporary or one-time items considered exceptional in nature and not related to the Company’s core operation
of
mining
assets
or
reflective
of
recurring
operating
performance.
Management
believes
Adjusted Net Earnings may assist investors and analysts to better understand the current and future operating performance of
the
Company’s
core mining
business.
Adjusted Net
Earnings
and
Adjusted
Net
Earnings
Per Share do not have a standard meaning under IFRS. They should not be considered in isolation, or as a substitute
for
measures
of
performance
prepared
in
accordance
with
IFRS
and
are
not
necessarily
indicative of earnings from mine operations, earnings, or cash flow from operations as determined under IFRS.

Cash
From
Operating
Activities
Before
Changes
in
Working
Capital:
Cash
from
Operating
Activities
before Changes
in
Working
Capital
is
a
non-IFRS
measure
with
no
standard
meaning
under
IFRS,
which
is
calculated by
the
Company
as
net
cash
from
operating
activities
less
working
capital
items.
The
Company
believes
that Net
Cash
from
Operating
Activities
before
Changes
in
Working
Capital,
which
excludes
these
non-cash
items, provides
investors
with
the
ability
to
better
evaluate
the
operating
cash
flow
performance
of
the
Company.

Net
Debt
and
Adjusted
Net
Debt:
The
Company
believes
that
in
addition
to
conventional
measures
prepared in accordance with IFRS, the Company and certain investors and analysts use net debt to evaluate the Company’s performance. Net debt does not have any standardized meaning prescribed under IFRS, and therefore it may not be comparable to similar measures employed by other companies. This measure is intended to provide additional information and should not be considered in isolation or as a substitute for measures
of
performances
prepared
in
accordance
with
IFRS.
Net
debt
is
calculated
as
the
sum
of
the
current and non-current portions of loans and borrowings, net of the cash and cash equivalent balance as at the balance sheet date. Adjusted Net Debt is calculated as Net Debt less fair value and other non-cash adjustments
that
will
not
result
in
a
cash
outflow
to
the
Company. The
Company
believes
that
Adjusted
Net Debt provides a better understanding of the Company’s liquidity.

Article content

EBITDA
and
Adjusted
EBITDA:
The
Company
believes
that
certain
investors
use
the
EBITDA
and
the
adjusted EBITDA (“Adjusted EBITDA”) measures to evaluate the Company’s performance and ability to generate operating
cash
flows
to
service
debt
and
fund
capital
expenditures.
EBITDA
and
Adjusted
EBITDA
do
not have a standardized meaning as prescribed under IFRS and should not be considered in isolation or as a substitute
for
measures
of
performance
prepared
in
accordance
with
IFRS.
The
Company
calculates
EBITDA as earnings or loss before taxes for the period excluding depreciation and depletion and finance costs. EBITDA excludes the impact of cash costs of financing activities and taxes and the effects of changes in working capital balances and therefore is not necessarily indicative of operating profit or cash flow from operations as determined under IFRS. Adjusted EBITDA is calculated by excluding one-off costs or credits relating
to
non-routine
transactions
from
EBITDA
that
are
not
indicative
of
recurring
operating
performance. Management believes this additional information is useful to investors in understanding the Company’s ability
to
generate
operating
cash
flow
by
excluding
from
the
calculation
these
non-cash
and
cash
amounts that are not indicative of
the recurring performance of
the underlying operations
for
the reporting periods.

Article content

Adjusted Net Debt to Adjusted EBITDA: The Adjusted Net Debt to Adjusted EBITDA measures provide investors
and
analysts
with
additional
transparency
about
the
Company’s
liquidity
position,
specifically,
the Company’s
ability
to
generate
sufficient
operating
cash
flows
to
meet
its
mandatory
interest
obligations
and pay down its outstanding debt balance in full at maturity. This measure is a Non-IFRS measure and it is intended to provide additional information and should not be considered in isolation or as a substitute for measures
of
performance prepared in accordance with IFRS.
