Cygnus Metals Limited (ASX: CY5; TSXV: CYG) (“Cygnus” or the
“Company”) is pleased to announce that it has made an outstanding
start to its exploration campaign at the Chibougamau Copper-Gold
Project in Quebec, Canada, with the first hole returning assays of
up to
2.5m @ 9.1% Copper.
Prior to the merger of Cygnus and Doré Copper
Mining Corp. closing, both teams executed a targeted exploration
program to test the immediate areas around the Corner Bay deposit,
looking for both additional structures and extensions to the
current resource.
The first drillhole from this program has
returned an intersection of 7.3m @ 4.2% Cu, 0.3g/t Au &
16.6g/t Ag, including 2.5m @ 9.1% Cu, 0.5g/t Au
& 31.4g/t Ag from a potential new lode ~250m east of
the existing resource in the footwall of the Corner Bay deposit.
Follow up downhole electromagnetics has since defined a significant
off hole electromagnetic anomaly (530m x 460m) to the north and
down dip of the intersection that has yet to be tested by
drilling.

About the Drilling and Geophysical
Results
The first hole of the program (CB-24-100)
targeting the footwall of the Corner Bay deposit has intersected a
potential new sub parallel lode with a high-grade drill result of
7.3m @ 4.2% Cu, 0.3g/t Au & 16.6g/t Ag from
317.8m, which includes 2.5m @ 9.1% Cu, 0.5g/t Au &
31.4g/t Ag.
The result highlights the potential for multiple
sub-parallel lodes at the Corner Bay deposit analogous to other
well-known deposits in the region. This new structure sits 250m to
the east of the Main Lode at Corner Bay in an area with very little
drilling. This presents an exciting target for follow up drilling
and an opportunity to add to the existing resources at Corner
Bay.
In addition, follow up electromagnetics (‘EM’)
completed on the recent drilling has defined a large (530m x 460m)
conductive plate offset to the north and down dip of drillhole
CB-24-100. EM is known to correspond well with the mineralisation
style at the Chibougamau mining camp, being primarily composed of
chalcopyrite with minor amounts of pyrite and pyrrhotite.
Historically, airborne EM has been used to make some of the
discoveries in the region, although ground and downhole EM has been
underutilised in more recent times. The large EM plate provides a
priority target for follow up exploration along this structure.

Ongoing Drilling
In line with the Company’s resource growth
strategy, drilling is underway with two diamond drill rigs. This
initial program will focus on resource growth opportunities
surrounding some of the existing deposits aiming to build upon the
existing high-grade resources. The Company looks forward to a high
volume of news flow during 2025 with ongoing drilling updates and
results.
About the Corner Bay
Deposit
Cygnus’ flagship Corner Bay deposit within the
Chibougamau Project is located 17km (straight line) south of the
Chibougamau processing facility. The deposit was discovered in the
1980s and has never been mined although ramp access was established
to 115m for the purpose of initial bulk sampling test work.
The deposit is the primary resource in the
combined Project resources, making up 79% of the total resource
with Indicated Mineral Resources of 2.7Mt @ 2.7% Cu & 0.3g/t Au
and Inferred Mineral Resources of 5.9Mt @ 3.4% Cu and 0.3g/t
Au.1
Mineralisation extends from surface and has been
defined over 1,000m of strike and to a depth of 1,350m with
mineralisation remaining open in all directions. The mineralisation
is structurally controlled and hosted as a north-south striking
quartz-carbonate vein with semi massive chalcopyrite and minor
pyrite mineralisation. The main lode has been crosscut and offset
by a large diabase dyke with an upper and lower portion of the lode
positioned either side of the dyke.
The Corner Bay deposit sits on the southern
flank of the Chibougamau pluton and has seen minimal exploration
compared to the north. The northern flank is host to 16 mined
deposits and has contributed a significant portion of the regions
historic production ~945,000t of copper and 3.5Moz of
gold.2 Corner Bay in the south shares comparable
lithological and structural characteristics to the northern
deposits, however, as the northern mines developed, multiple
sub-parallel lodes were subsequently discovered within the same
structural corridor. Due to the relatively early stage of defining
the Corner Bay deposit, potential parallel lodes and resource
extension have not yet been properly explored and the latest
intersection highlights the potential for additional sub-parallel
lodes within the immediate vicinity of the current resources.
About the Chibougamau Copper-Gold
Project
The Chibougamau copper-gold project
(“Chibougamau Project”) is located in central Quebec, Canada
approximately 480km due north of Montreal. The province of Quebec
has been recognised as a top ten global mining investment
jurisdiction in the 2023 Fraser Institute Annual Survey of Mining
Companies. The project has excellent infrastructure with a local
mining town, sealed highway, airport, regional rail infrastructure
and access to hydro power via installed powerlines.
The Chibougamau Project is centred on the
Chibougamau pluton with a district wide historic production of
53.5Mt @ 1.8% Cu and 2.1g/t Au2 with periodic mining between the
early 1900s and 2008. Over this long mining history, the district
has produced over 945,000t of copper and 3.5Moz of gold from 16
former producing mines.2
The Chibougamau Project has high-grade resources
including a Measured and Indicated Mineral Resources of 3.6Mt at
2.5% Cu & 0.6g/t Au and Inferred Mineral Resources of 7.2Mt at
3.0% Cu & 1.1g/t Au with significant potential to grow.1
The Company has a clear strategy to:
- Rapidly grow the
resource through brownfield exploration and investment in drilling;
and
-
Advance the project towards development through study work and
utilising existing infrastructure.
The Company sees a huge opportunity to create
shareholder value by an established high-grade resource with
opportunity for growth, excellent infrastructure, 900ktpa
processing facility and clear pathway to production, all within a
quality endowed mineral terrane that has seen minimal modern
exploration.

Section 1 Sampling Techniques and Data
Criteria |
JORC Code explanation |
Commentary |
Sampling techniques |
Nature and quality of sampling (eg cut channels, random chips, or
specific specialised industry standard measurement tools
appropriate to the minerals under investigation, such as down hole
gamma sondes, or handheld XRF instruments, etc). These examples
should not be taken as limiting the broad meaning of sampling. |
- All current drilling
conducted at the Chibougamau Project was completed under the
supervision of a registered professional geologist as a Qualified
Person (QP) who is responsible and accountable for the planning,
execution, and supervision of all exploration activity as well as
the implementation of quality assurance programs and
reporting.
- All drilling
reported is NQ2 (47.8 mm diameter)
|
Include reference to measures taken to ensure sample representivity
and the appropriate calibration of any measurement tools or systems
used. |
- All sample
collection, core logging, and specific gravity determinations were
completed by Cygnus Metals under the supervision of a
professionally qualified registered geologist.
- NQ core was marked
for splitting during logging and is sawn using a diamond core saw
with a mounted jig to assure the core is cut lengthwise into equal
halves.
- Half of the cut core
is placed in clean individual plastic bags with the appropriate
sample tag.
- QA/QC is done in
house by Cygnus Metals geologists with oversight from the Senior
Geologist. The check samples (blanks and standards – 4% of total
samples with another 2% of core duplicates taken on half split
core) that were inserted into the sample batches are verified
against their certified values and are deemed a pass if they are
within 3 standard deviations of the certified value. The duplicates
are evaluated against each other to determine mineralization
distribution (nugget). If there are large discrepancies in the
check samples, then the entire batch is requested to be re-assayed.
The samples are then placed in bags for shipment to the offsite
laboratory’s facility.
- The remaining half
of the core is retained and incorporated into Cygnus’s secure, core
library located on the property
|
Aspects of the determination of mineralisation that are Material to
the Public Report.In cases where ‘industry standard’ work has been
done this would be relatively simple (eg ‘reverse circulation
drilling was used to obtain 1 m samples from which 3 kg was
pulverised to produce a 30 g charge for fire assay’). In other
cases more explanation may be required, such as where there is
coarse gold that has inherent sampling problems. Unusual
commodities or mineralisation types (eg submarine nodules) may
warrant disclosure of detailed information. |
- Industry standard
sampling practices were used with sample lengths ranging from 0.3 m
to 1.0 m and respected geological contacts. Sample tags were placed
at the beginning of each sample interval and the tag numbers were
recorded in an MS Excel database.
- Sampling practice is
considered to be appropriate to the geology and style of
mineralisation
|
Drilling techniques |
Drill type (eg core, reverse circulation, open-hole hammer, rotary
air blast, auger, Bangka, sonic, etc) and details (eg core
diameter, triple or standard tube, depth of diamond tails,
face-sampling bit or other type, whether core is oriented and if
so, by what method, etc). |
- Diamond core was
drilled using surface diamond rigs with industry recognised
contractors Miikan Drilling. Miikan is a joint venture between
Chibougamau Diamond Drilling Ltd., the First Nations community of
Ouje-Bougoumou and the First Nations community of Mistissini both
located in the Eeyou Istchee territory.
- Drilling was
conducted using NQ core size
- Directional surveys
have been taken at 50m intervals
|
Drill sample recovery |
Method of recording and assessing core and chip sample recoveries
and results assessed.Measures taken to maximise sample recovery and
ensure representative nature of the samples.Whether a relationship
exists between sample recovery and grade and whether sample bias
may have occurred due to preferential loss/gain of fine/coarse
material. |
- Diamond core
recovery was measured for each run and calculated as a percentage
of the drilled interval.
- Overall, the core
recoveries are excellent in the Chibougamau area
|
Logging |
Whether core and chip samples have been geologically and
geotechnically logged to a level of detail to support appropriate
Mineral Resource estimation, mining studies and metallurgical
studies. |
- All core was
geologically and geotechnically logged. Lithology, veining,
alteration and mineralisation are recorded in multiple tables of
the drillhole database
|
Whether logging is qualitative or quantitative in nature. Core (or
costean, channel, etc) photography. |
- Geological logging
of core is qualitative and descriptive in nature.
|
The total length and percentage of the relevant intersections
logged. |
- 100% of the core has
been logged
|
Sub-sampling techniques and sample preparation |
If core, whether cut or sawn and whether quarter, half or all core
taken.If non-core, whether riffled, tube sampled, rotary split, etc
and whether sampled wet or dry.For all sample types, the nature,
quality and appropriateness of the sample preparation
technique.Quality control procedures adopted for all sub-sampling
stages to maximise representivity of samples.Measures taken to
ensure that the sampling is representative of the in-situ material
collected, including for instance results for field
duplicate/second-half sampling.Whether sample sizes are appropriate
to the grain size of the material being sampled. |
- The NQ2 diameter the
core was sawn in half following a sample cutting line determined by
geologists during logging and submitted for analysis on nominal 1m
intervals or defined by geological boundaries determined by the
logging geologist
- Each core sample is
assigned a tag with a unique identifying number. Sample lengths are
typically one metre but can be depending on zone mineralogy and
boundaries.
- This sampling
technique is industry standard and deemed appropriate.
|
Quality of assay data and laboratory tests |
The nature, quality and appropriateness of the assaying and
laboratory procedures used and whether the technique is considered
partial or total. |
- Sample (NQ size half
core) preparation and fire assay analysis were done at Bureau
Veritas Commodities Canada Ltd (“BV”) in Timmins, Ontario, and
ICP-ES multi-elements analysis was done at BV in Vancouver,
B.C.
- Samples were
weighed, dried, crushed to 70% passing 2 mm, split to
250 g, and pulverized to 85% passing 75 µm.
- Samples are fire
assayed for gold (Au) (30 g) and multi-acid digestion ICP-ES
finish, for 23 elements (including key elements Ag, Cu, Mo).
- Samples assaying
>10.0 g/t Au are re-analysed with a gravimetric finish using a
30 g charge. Samples assaying >10% Cu are re-analysed with a
sodium peroxide fusion with ICP-ES analysis using a 0.25 g
charge.
|
For geophysical tools, spectrometers, handheld XRF instruments,
etc, the parameters used in determining the analysis including
instrument make and model, reading times, calibrations factors
applied and their derivation, etc. |
|
Nature of quality control procedures adopted (eg standards, blanks,
duplicates, external laboratory checks) and whether acceptable
levels of accuracy (i.e. lack of bias) and precision have been
established. |
- Laboratory QC
procedures involve the use of internal certified reference material
as assay standards, along with blanks, duplicates and
replicates
|
Verification of sampling and assaying |
The verification of significant intersections by either independent
or alternative company personnel. |
- Verification of
sampling was made by Cygnus Metals and other professional
consultant geologists
|
The use of twinned holes. |
|
Documentation of primary data, data entry procedures, data
verification, data storage (physical and electronic)
protocols. |
- All logging data was
completed, core marked up, logging and sampling data was entered
directly into the database.
- The logged data is
stored on the site server directly.
|
Discuss any adjustment to assay data. |
- There was no
adjustment to the assay data
|
Location of data points |
Accuracy and quality of surveys used to locate drill holes (collar
and down-hole surveys), trenches, mine workings and other locations
used in Mineral Resource estimation. |
- The location of the
drillholes and the aiming points for the orientation of the
drillholes were indicated on the ground using identified stakes.
The stakes marking the location of the drillholes were set up and
located with a Garmin GPS model “GPSmap 62s” (4m accuracy)
- Surveys are
collected using a Reflex EZ-Shot® single-shot electronic instrument
with readings collected at intervals of approximately every 30 m
downhole plus a reading at the bottom of the hole
|
Specification of the grid system used. |
- The grid system used

|
Quality and adequacy of topographic control. |
- A Digital Terrane
Model (DTM) has been used to accurately plot the vertical position
of the holes
|
Data spacing and distribution |
Data spacing for reporting of Exploration Results. |
- The spacing is
considered appropriate for this type of exploration
|
Whether the data spacing and distribution is sufficient to
establish the degree of geological and grade continuity appropriate
for the Mineral Resource and Ore Reserve estimation procedure(s)
and classifications applied. |
- No resource
estimation is made
|
Whether sample compositing has been applied. |
- No sample
compositing has been applied
|
Orientation of data in relation to geological structure |
Whether the orientation of sampling achieves unbiased sampling of
possible structures and the extent to which this is known,
considering the deposit type. |
- Drilling is
orientated approximately at right angles to the currently
interpreted strike of the known interpreted mineralisation.
Reported intersections appear close to true width
|
If the relationship between the drilling orientation and the
orientation of key mineralised structures is considered to have
introduced a sampling bias, this should be assessed and reported if
material. |
- No bias is
considered to have been introduced by the existing sampling
orientation
|
Sample security |
The measures taken to ensure sample security. |
- Core was placed in
wooden core boxes close to the drill rig by the drilling
contractor. The core was collected daily by the drilling contractor
and delivered to the secure core logging facility. Access to the
core logging facility is limited to Cygnus employees or
designates
|

Geology |
Deposit type, geological setting and style of mineralisation. |
- Corner Bay and
Devlin are located at the northeastern extremity of the Abitibi
subprovince in the Superior province of the Canadian Shield and are
examples of Chibougamau-type copper-gold deposits. The Abitibi
subprovince is considered as one of the largest and best-preserved
greenstone belts in the world and hosts numerous gold and base
metal deposits.
- The Corner Bay
deposit is located on the southern flank of the Doré Lake Complex
(DLC). It is hosted by a N 15° trending shear zone more or less
continuous with a strong 75° to 85° dip towards the west. The host
anorthosite rock is sheared and sericitized over widths of 2 m to
25 m. The deposit is cut by a diabase dyke and is limited to the
north by a fault structure and to the south by the LaChib
deformation zone.
- The Corner Bay
deposit consists of three main mineralized lodes (subparallel Main
Lode 1 and Main Lode 2 above the dyke, and Main Lode below the dyke
that make up the bulk of the deposit. The Corner Bay deposit has
been traced over a strike length to over 1,100 m to a depth of
1,350 m and remains open at depth.
- The mineralization
is characterized by veins and/or lenses of massive to semi-massive
sulphides associated with a brecciated to locally massive
quartz-calcite material. The sulphide assemblage is composed of
chalcopyrite, pyrite, and pyrrhotite with lesser amounts of
molybdenite and sphalerite. Late remobilized
quartz-chalcopyrite-pyrite veins occur in a wide halo around the
main mineralization zones.
- Devlin is a
flat-lying, copper-rich lodes-hosted deposit in a polygenic igneous
breccia that is less than 100 m from the surface. The tabular
bodies have been modelled as four nearly horizontal lodes: a more
continuous lower zone and three smaller lodes comprising the upper
zone. Mineralization is reflected as a fracture zone often composed
of two or more sulphide-quartz lodes and stringers. Thickness of
the mineralized zones range from 0.5 m to 4.4 m. It has been
diluted during modelling to reflect a minimum mining height of 1.8
m.
- The Joe Mann deposit
is characterized by east-west striking shear hosted lodes that
extend beyond 1,000 m vertically with mineralization identified
over a 3 km strike length. These shear zones form part of the
Opawica-Guercheville deformation zone, a major deformation corridor
cutting the mafic volcanic rocks of the Obatogamau Formation in the
north part of the Caopatina Segment. The gabbro sill hosts the Main
Zone and the West Zone at the mine, while the South Zone is found
in the rhyolite. These three subvertical E-W (N275°/85°)
ductile-brittle shear zones are sub-parallel to stratigraphy and to
one another, with up to 140 m to 170 m of separation between them.
These shear zones are hosted within a stratigraphic package
composed of iron-magnesium (Fe-Mg) carbonate and sericite altered
gabbro sills, sheared basalts, and intermediate to felsic tuffs
intruded by various felsic intrusions. The Joe Mann gold
mineralization is hosted by decimetre scale quartz-carbonate lodes
(Dion and Guha 1988). The lodes are mineralized with pyrite,
pyrrhotite, and chalcopyrite disposed in lens and lodelets parallel
to schistosity, and occasionally visible gold. There are some other
minor, mineralized structures, e.g., North and South-South Zones,
with limited vertical and horizontal extensions.

Drill hole Information |
A summary of all information material to the understanding of the
exploration results including a tabulation of the following
information for all Material drill holes:
- easting and northing of the drill hole collar
- elevation or RL (Reduced Level – elevation above sea level in
metres) of the drill hole collar
- dip and azimuth of the hole
- down hole length and interception depth
- hole length.
If the exclusion of this information is justified on the basis that
the information is not Material and this exclusion does not detract
from the understanding of the report, the Competent Person should
clearly explain why this is the case. |
- All requisite
drillhole information is tabulated elsewhere in this release. Refer
Appendix A of the body text
|
Data aggregation methods |
In reporting Exploration Results, weighting averaging techniques,
maximum and/or minimum grade truncations (eg cutting of high
grades) and cut-off grades are usually Material and should be
stated. |
- All drill hole
intersections are reported above a lower cut-off grade of 0.5%
copper.
|
Where aggregate intercepts incorporate short lengths of high-grade
results and longer lengths of low-grade results, the procedure used
for such aggregation should be stated and some typical examples of
such aggregations should be shown in detail. |
- A maximum of 1m
internal waste was allowed
|
The assumptions used for any reporting of metal equivalent values
should be clearly stated. |
- No metal equivalents
reported
|
Relationship between mineralisation widths and intercept
lengths |
These relationships are particularly important in the reporting of
Exploration Results.If the geometry of the mineralisation with
respect to the drill hole angle is known, its nature should be
reported.If it is not known and only the down hole lengths are
reported, there should be a clear statement to this effect (eg
‘down hole length, true width not known’). |
- All intersections
reported in the body of this release are down hole.
- The majority of the
drill holes in the database are drilled as close to orthogonal to
the plane of the mineralized lodes as possible.
- Only down hole
lengths are reported.
|
Diagrams |
Appropriate maps and sections (with scales) and tabulations of
intercepts should be included for any significant discovery being
reported These should include, but not be limited to a plan view of
drill hole collar locations and appropriate sectional views. |
- Included elsewhere
in this release. Refer figures in the body text
|
Balanced reporting |
Where comprehensive reporting of all Exploration Results is not
practicable, representative reporting of both low and high grades
and/or widths should be practiced to avoid misleading reporting of
Exploration Results. |
- All results greater
than 0.5% Cu and 0.5g/t Au have been reported at greater than 1m
width
|
Other substantive exploration data |
Other exploration data, if meaningful and material, should be
reported including (but not limited to): geological observations;
geophysical survey results; geochemical survey results; bulk
samples – size and method of treatment; metallurgical test results;
bulk density, groundwater, geotechnical and rock characteristics;
potential deleterious or contaminating substances. |
- Appropriate plans
are included in the body of this release.
|
Further work |
The nature and scale of planned further work (eg tests for lateral
extensions or depth extensions or large-scale step-out
drilling).Diagrams clearly highlighting the areas of possible
extensions, including the main geological interpretations and
future drilling areas, provided this information is not
commercially sensitive. |
- The Company will be
conducting drill testing of additional mineralisation as well as
step out drilling of existing lodes to further enhance the
resources quoted in this release. More information is presented in
the body of this report.
- Diagrams in the main
body of this release show areas of possible resource extension on
existing lodes. The company continues to identify and assess
multiple other target areas within the property boundary for
additional resources.
