Calibre Mining Corp. (TSX: CXB; OTCQX: CXBMF) (the
"Company" or "Calibre") is pleased to announce the results of the
Company’s updated Mineral Resources (“Resources”) and Mineral
Reserves (“Reserves”) for its Nicaragua and Nevada properties as of
December 31, 2023. Reserves have grown in both jurisdictions net of
depletion since acquisition of each asset. As demonstrated by the
team’s track record, Calibre continues to efficiently make new
discoveries and convert discoveries into Reserves as evidenced at
the VTEM gold corridor within the Limon Mine Complex which has seen
year over year Reserve growth of 36%. The VTEM corridor now
contains 1.25 Mt averaging 8.25 g/t Au for 332 koz in Reserves with
multiple kilometres of strike potential and an ongoing 50,000 m
drill program.
Nicaragua Mineral
Reserves (December 31, 2023)
Highlights
- Nicaragua:
Increase in Reserves net of production depletion of 4% in 2023 to
1.13 Moz;
- Nevada: Increase
in Reserves net of production depletion of 12% in 2023 to 0.30
Moz;
- Company wide
significant mineral endowment of over 4.1 Moz of Reserves, 8.6 Moz
of Measured and Indicated Resources (inclusive of Reserves) and 3.6
Moz of Inferred Resources;
- Valentine Gold
Mine’s significant mineral endowment of 2.7 Moz of Reserves and
3.96 Moz of Measured and Indicated Resources (inclusive of
Reserves) and 1.10 Moz of Inferred Resources (further detailed in
the tables below) (see news release dated January 26, 2024);
and
- >130,000 m
Resource expansion and discovery drill programs underway across all
assets.
Darren Hall, President and Chief
Executive Officer of Calibre stated: “I am very pleased to
see another year of Reserve growth net of depletion in both
operating jurisdictions. We have crystalized a significant portion
of our Resources into Reserves for a record 1.42 Moz in Nicaragua
and Nevada, net of record 2023 production of 283,525 ounces.
Nicaragua continues to deliver with Reserves at 1.13 Moz providing
a robust base from which to deliver. With our recent acquisition of
the Valentine Gold Mine, our company wide consolidated Reserves
stand at 4.1 Moz, a more than 10-fold increase since Q4 2019 net of
825 koz of production. Importantly Reserves have grown more 36%
year over year at our emerging flagship project, the VTEM gold
corridor at Limon. In Nevada we’ve grown Reserves over 50% net of
production depletion since closing the acquisition in 2021.”

Link – Detailed 2023 Mineral Resource and
Mineral Reserve Tables
Quality Assurance/Quality Control
CanadaQA/QC protocols followed
at the Valentine Gold Mine include the insertion of blanks and
standards at regular intervals in each sample batch. Drill core is
cut in half with one half retained at site, the other half tagged
and sent to Eastern Analytical Limited in Springdale, NL. Eastern
Analytical is ISO 17025 accredited for Atomic Absorption
Spectroscopy for gold following fire assay preparation methods and
is independent of Calibre. All samples are analyzed for
Au by fire assay (30g) with AA finish. Samples that assayed greater
than or equal to 300 ppb gold were subjected to a total pulp
metallic sieve procedure. Samples that fall within mineralized
zones that are <300 ppb are also reanalyzed by screen metallics.
The analytical results are captured in an acQuire database, which
is programmed to utilize the screen metallic values over the
standard fire assays if data is available.
Nicaragua Calibre maintains a
Quality Assurance/Quality Control ("QA/QC") program for all its
exploration projects using industry best practices. Key elements of
the QA/QC program include verifiable chain of custody for samples,
regular insertion of certified reference standards and blanks, and
duplicate check assays. Drill core is halved and shipped in sealed
bags to Bureau Veritas in Managua, Nicaragua, an independent
analytical services provider with global certifications for Quality
Management Systems ISO 9001:2008, Environmental Management:
ISO14001 and Safety Management OH SAS 18001 and AS4801. Prior to
analysis, samples are prepared at Veritas' Managua facility and
then shipped to its analytical facilities in Vancouver, Canada.
Half core samples are also shipped in sealed bags to ALS’ prep
facility in Managua, Nicaragua. ALS has a global quality program
that includes internal and external inter-laboratory test programs
and regularly scheduled internal audits that meet all requirements
of ISO/IEC 17025:2017 and ISO 9001:2015. Prior to analysis samples
are prepared at ALS’ Managua facility then shipped to its
analytical facility in Lima, Peru. Gold analyses are routinely
performed via fire assay/AA finish methods. For greater precision
of high-grade material, samples assaying 10 g/t Au or higher
are re-assayed by fire assay with gravimetric finish. Analyses for
silver and other elements of interest are performed via Induction
Coupled Plasma (ICP).
NevadaKey elements of the QA/QC
program include the insertion of assay standards, blanks, and
duplicates in the sample stream to ensure the assay lab results are
within specified performance levels. Down hole deviation surveys
are provided by International Directional Services, utilizing a
surface recording gyroscope, and by trained drill crews operating a
north seeking gyroscope supplied by REFLEX. RC drilling was
performed by Boart Longyear of Salt Lake City, Utah and Alford
Drilling from Elko, Nevada. Assays were performed by ALS, Reno
where fire assays were determined on a 30-gram charge with an AAS
finish. An additional cyanide leach assay was also completed. ALS
carries ISO/IEC 17025:2017 certification.

model with mineralized zones defined by wireframed solids (HG=high
grade, LG= low grade, sap=saprolite).
- A base cutoff grade of 0.5 g/t
AuEq was used for reporting mineral resources.
- Gold Equivalent (AuEq) grades have
been calculated using $1300/oz Au for gold, $2.40/lb for Copper,
and $20.00/oz Ag for silver and metallurgical recoveries are
assumed to be equal for all metals.
- Resource Estimates for the
Primavera project are detailed in the NI 43-101 Technical Report
titled ‘Primavera Project ‘by Todd McCracken, dated January 31,
2017.
- The quantity and grade of reported
Inferred resources in this estimation are uncertain in nature and
there has been insufficient exploration to define these Inferred
resources as an indicated or measured resource. It is uncertain if
further exploration will result in upgrading them to indicated or
measure mineral resource category.
- Numbers may not add exactly due to
rounding.
- Mineral Resources that are not
mineral reserves do not have demonstrated economic viability.

and reported using a minimum internal gold cutoff grade of 0.003
oz/st Au (0.10 g/t Au).
- Measured and Indicated Mineral
Resources presented are inclusive of Mineral Reserves. Inferred
Mineral Resources are not included in Mineral Reserves.
- Mineral Resources are not Mineral
Reserves and do not have demonstrated economic viability. There has
been insufficient exploration to define the inferred resources
tabulated above as an indicated or measured mineral resource,
however, it is reasonably expected that the majority of the
Inferred Mineral Resources could be upgraded to Indicated Mineral
Resources with continued exploration. There is no certainty that
any part of the Mineral Resources estimated will be converted into
Mineral Reserves.
- Numbers in the table have been
rounded to reflect the accuracy of the estimate and may not sum due
to rounding.
- Mr. Benjamin Harwood, M.Sc., P.
Geo. of Calibre is responsible for reviewing and approving the Pan
mine open pit Mineral Resource Estimate. Mr. Harwood is a Qualified
Person (“QP”) as set out in NI 43-101.The Qualified Person (QP) is
not aware of any environmental, permitting, legal, title, taxation,
socioeconomic, marketing, political, or other relevant factors that
could materially affect the Mineral Resource estimate.
Note 9 – Gold Rock Mineral Resource Notes
- The effective date of the Mineral
Resource is Mar 31, 2020.
- Mineral Resources are not Mineral
Reserves and do not have demonstrated economic viability. There is
no certainty that any part of the Mineral Resources estimated will
be converted into Mineral Reserves.
- The preliminary economic assessment
for Gold Rock is preliminary in nature and includes Inferred
Mineral Resources that are too speculative geologically to have the
economic considerations applied to them that would enable them to
be categorized as Mineral Reserves, and there is no certainty that
the preliminary economic assessment will be realized.
- In the table above and subsequent
text, the abbreviation “st” denotes US short tons.
- Mineral resources stated as
contained within a constrained pit shell; pit optimization was
based on an assumed gold price of US$1,700/oz, an ore mining cost
of US$2.09/st, a waste mining cost of $1.97/st, an ore processing
and G&A cost of US$3.13/st, and pit slopes between 45-50
degrees.
- Mineral resources are reported
using an internal gold cut off grade of 0.003 oz/st Au for blocks
flagged as Argillic altered or as unaltered and a cutoff of 0.004
oz/st Au for blocks flagged as Silicic altered.
- Numbers in the table have been
rounded to reflect the accuracy of the estimate and may not sum due
to rounding.
Note 10 – Golden Eagle Mineral Resource
Notes
- The effective date of the Mineral
Resource is Mar 31, 2020.
- The Qualified Person for this
estimate is Terre Lane of GRE.
- Mineral Resources are not Mineral
Reserves and do not demonstrate economic viability.
- Numbers in the table have been
rounded to reflect accuracy of the estimate and may not sum due to
rounding.
- The Mineral Resource is based on
gold cutoff grade of 0.014 troy ounces per short ton (0.48 grams
per tonne) at an assumed gold price of $1,500/tr oz, assumed mining
cost of $1.06/st waste, assumed mining costs of $2.02/st
mineralized mineral, assumed processing case of $12.75/st
mineralized material, assumed G&A cost of $0.74/st mineralized
material, an assumed metallurgical recovery of 80% and pit slopes
of 45 degrees.
- The pit layback is not constrained
to Fiore controlled land. Additional land must be acquired or
otherwise made available for the pit layback, waste rock dumps,
tailings facilities, and other surface infrastructure.
Note 11 – Valentine Gold Mine Mineral Resource
Notes
- CIM (2014) definitions were
followed for mineral resources.
- The effective date for the
Leprechaun, Berry, and Marathon MREs is June 15, 2022. The
effective date for the Sprite and Victory MREs is November 20,
2020. The independent Qualified Person, as defined by NI 43-101, is
Mr. Roy Eccles, P.Geo. (PEGNL) of APEX Geoscience Ltd.
- Open pit mineral resources are
reported within a preliminary pit shell at a cut-off grade of 0.3
g/t Au. Underground mineral resources are reported outside the pit
shell at a cut-off grade of 1.36 g/t Au. Mineral resources are
reported inclusive of mineral reserves.
- Mineral resources are estimated
using a long-term gold price of US$1,800 per ounce, and an exchange
rate of 0.76 USD/CAD.
- Mineral resources reported
demonstrate reasonable prospect of eventual economic extraction, as
required under the CIM 2014 standards as MRMR.
- The mineral resources would not be
materially affected by environmental, permitting, legal, marketing,
and other relevant issues based on information currently
available.
- Numbers may not add or multiply
correctly due to rounding.
Note 12 – Valentine Gold Mine Mineral Reserve
Notes
- The mineral reserve estimates were
prepared by Marc Schulte, P.Eng. (who is also an independent
Qualified Person), reported using the 2014 CIM Definition
Standards, and have an effective date of November 30, 2022.
- Mineral reserves are mined tonnes
and grade; the reference point is the mill feed at the primary
crusher.
- Mineral reserves are reported at a
cut-off grade of 0.38 g/t Au.
- Cut-off grade assumes US$1,650/oz
Au at a currency exchange rate of US$0.78 per C$1.00; 99.8% payable
gold; US$5.00/oz off-site costs (refining and transport); and uses
an 87% metallurgical recovery. The cut-off grade covers processing
costs of $15.20/t, administrative (G&A) costs of $5.30/t, and a
stockpile rehandle cost of $1.85/t.
- Mined tonnes and grade are based on
a smallest mining unit (SMU) of 6 m x 6 m x 6 m, including
additional mining losses estimated for the removal of isolated
blocks (surrounded by waste) and low-grade (<0.5 g/t Au) blocks
bounded by waste on three sides.
- Numbers have been rounded as
required by reporting guidelines.
