Dotted Lake: Technical
Update, Inversion & Drill Targets
Panther Metals PLC (LSE:PALM) the
company focused on mineral exploration in Canada, is pleased to
provide an exciting update with regards to geophysical
three-dimensional ("3D") inversion modelling and predictive Centre
for Exploration Targeting grid analysis in support of drill
targeting at the Dotted Lake Project ("Dotted Lake" or the
"Project"), on the north limb of the Schreiber-Hemlo Greenstone
Belt in Ontario, Canada.
Highlights
·
Abitibi Geophysics have completed geophysical
modelling and interpretation of Panther's airborne geophysical
survey datasets to assist in drill targeting of nickel, cobalt,
copper, gold and platinum group element ("PGE") bearing sulphide
mineralisation associated with the mafic-ultramafic intrusive
complex in the north-east of the Dotted Lake Project
area.
·
Centre for Exploration Targeting ("CET") grid
analysis has identified target zones of significant structural
complexity that present preferential sites for the development of
mineral deposits.
·
Ultramafic intrusive complex modelled in 3D from
magnetic susceptibility inversion processing (Figure 1).
·
Electromagnetic ("EM") conductor 3D plate
modelling has identified two parallel conductors, situated on the
northern flank of the ultramafic intrusive complex.
o Longer of the two EM conductors (A) has a 500m strike length,
with its eastern end interpreted to plunge to depth below the limit
of the current survey data (Figure 1 & 2).
·
Abitibi have identified a total of twenty-one
prioritised drilling targets based on the CET and EM conductor
plate modelling. The Abitibi targets are based on geophysical data
processing alone.
·
Abitibi targets show a very strong correlation
with Panther's soil geochemical anomalies and highly anomalous
985ppm copper and REEs in lake sediments (Figure
3).
·
Highest priority Abitibi CET and EM targets are
located directly below or in close lateral proximity to very
anomalous Ni, Co, Cu and Au soil results, reinforcing and
prioritising the associated drilling targets.
·
Exploration strategies involving drill targeting
of geophysical modelled ultramafic intrusive feeder dykes
coincident with soil anomalies have led to multiple discoveries of
high-grade nickel and copper and PGE, to the east of Dotted Lake by
GT Resources Inc. Preliminary interpretation suggests that the
Dotted Lake ultramafic intrusive complex is part of the same
mineralising system.
Nick O'Reilly,
professional geologist and Panther Chairman,
commented:
"The 3D inversion modelling and conductive
plate modelling of Panther's airborne geophysical survey data has
reinforced and supplemented the base metal, PGE and gold anomalies
identified by the Company's soil geochemical survey and prospecting
work.
The delineation of a 500m plus long,
plunging conductor located on the northern flank of an ultramafic
intrusive body located directly below highly anomalous nickel,
cobalt and copper in soil geochemical survey points presents a very
compelling target, as do the numerous CET targets which are also
coincident with strong soil anomalies and which are adjacent to one
of the region's highest copper-in-lake sediment copper results
(985ppm Cu), in the north of the Project area at Lampson
Lake."
Darren
Hazelwood, CEO commented:
"The Dotted Lake Project is located
in a largely unexplored area on a wider greenstone belt and region
that's a prolific host of numerous mines and known
deposits.
With each additional work stream our
confidence in the Project increases, both as the geological
framework of the area becomes better understood and as we continue
to monitor the exploration successes made by others
nearby.
We've witnessed multiple levels of
interest in the Project and seen Glencore invest in a neighbouring
project whose geology correlates encouragingly with our own
understanding of Dotted Lake. The independent inversion modelling
we've announced today has already had a very positive impact on the
Project, and the final pieces are coming into place to make a
significant advancement.
It's without doubt that the Dotted
Lake Project contains all the required discovery ingredients, both
geologically and corporately. We'll continue wider discussions on
the Project but in the meantime, we are focused on drill pad
locations and putting the required logistics in place.
Panther owns Dotted Lake 100%
outright, unusual for Canada there are with no underlying financial
instruments attached, and we look forward to our strategy of
maintaining that structure and delivering for the Company and our
shareholders."

Geophysical Modelling
Panther retained Abitibi Geophysics
Inc ("Abitibi") to conduct geophysical modelling and interpretation
of the ProspecTEM airborne geophysical survey datasets previously
obtained by Panther, to assist in drill targeting of nickel,
cobalt, copper, gold and platinum group element ("PGE") bearing
sulphide mineralisation targeted in association with the
mafic-ultramafic intrusive complex in the north-eastern sector of
the Dotted Lake Project area.
The Project was covered by Panther's
818 line-km airborne magnetic ("MAG") and time-domain
electromagnetic ("TDEM") geophysical survey in 2020 with the data
acquired on survey lines spaced 50 metres apart. The Abitibi
follow-up recommendations are focused on a 5.6 km by 2.0 km in the
north-eastern part of the Project area.
The MAG survey data identified
large-scale magnetic formations as well as numerous dykes and
sills. The magnetic response is primarily proportional to the iron
content of the mafic rocks, the first vertical derivative of the
magnetic field identified the local variations facilitating the
interpretation of faults, shear zones, and dykes.
The southern portion of the Project
area is mostly non-magnetic granites which are intruded by magnetic
sills and dykes. The northern and southwestern portions of the
Project area display a moderately magnetic east-west trending
package of mafic volcanic rocks, whilst in the east of the Project,
just south of the mafic volcanics, a strongly magnetic ultramafic
intrusive complex is clearly identified, with two additional
ultramafic intrusions interpreted to its west. These additional
ultramafic bodies appear to be related to the complex but
disconnected by major structural features.
Inversion Modelling
A 3D inversion of the magnetic data
was commissioned to characterise the delineated magnetic features
and therefore estimate their magnetic susceptibility and 3D
geometry.
An unconstrained 3D magnetic
inversion was performed on the residual grid using Seequent's
Magnetisation Vector Inversion ("MVI") as well as a conventional
magnetic inversion. Since remanent magnetisation is suspected in
some magnetic anomalies, the MVI algorithm was utilised to
calculate the magnetic susceptibility model for the study grid
rather than the conventional inversion.
The final inversion result of the
ultramafic intrusive complex is illustrated in Figure 1, as a 3D voxel of the MVI
magnetic susceptibility. To estimate the depth extension and dip of
the detected magnetic sources, as well as to locate possible deep
shears, 6 horizontal slices were extracted from the MVI magnetic
susceptibility model at different elevations.
Centre for Exploration Targeting Grid
Analysis
A structural and predictive
targeting analysis was conducted using the Centre for Exploration
Targeting ("CET") grid analysis method on the TMI-RTP (total
magnetic intensity - reduced to pole) grid.
Mineralisation often occurs in the
regions of structural complexity adjacent to shear zones which act
as conduits for mineralising fluids.
The CET grid analysis method
identifies the discontinuities that correspond to both lithological
boundaries and shear zones by using texture analysis and symmetry
feature detection techniques. It uses fractal analysis to find
zones of structural complexity.
The most prospective areas are those
where inferred structural complexity occurs adjacent to the regions
of magnetic discontinuity. This method then analyses structural
associations to locate their intersections, as well as to find
variations in the orientation of neighbouring structures. Finally,
it generates an orientation entropy heat map that highlights the
areas that are prospective.
The Dotted Lake CET analysis has
identified target zones of significant structural complexity that
are prospective for hosting base metal, PGE and gold deposits in
the Project. The CET results are presented on Figures 2 & 3.
Electromagnetic Interpretation
Electromagnetic geophysical methods
are used to measure sub-surface electrical conductivity. In mineral
exploration these techniques can be applied to identify finite
conductive features that may be related to conductive massive
sulphide lenses and mineralised bodies.
The Dotted Lake survey displays weak
subvertical TDEM conductors in the ultramafic intrusive complex.
As the TDEM data appears to be buried in noise apart from a
small conductive area, a filter was applied to help identify
broader conductive trends. An upward continuation (to 100m) was
used to show large scale conductivity features. Some subtle broad
conductive trends can be identified which appears to be related to
large scale shears/faults.
The primary conductive trend (A) is
approximately 500 metres in width. The trend displays a slight
arcuate shape along strike as well as along its depth-to-top. It is
modelled using 5 plates to account for its geometry and the trend
appears to plunge to depth at its eastern end.
The shape of the conductor generally
agrees with the shape of the magnetic ultramafic intrusion
associated with it. A second localised anomaly (B) located about
240 metres south has a similar EM response and is likely related to
the same source/composition as the A trend.
Based on the survey data alone, no
clear conclusion can be made regarding the depth extent of the
conductive lenses.
Abitibi have recommended drilling of
the A trend, commencing where the conductivity is highest, where it
is probably nearer to the surface, with further drilling centred on
either side targeting the deeper modelled depth-to-top. Drill
testing of the B trend would follow-on dependant on the information
gleaned from the preceding holes.
Findings
Based on the geophysical data
processing alone, not Panther's highly prospective soil sampling
dataset, Abitibi have identified a total of twenty-one prioritised
drilling targets based on the CET and EM conductor plate modelling,
in the focused interest area in the north and northeast of the
Dotted Lake project.
A subsequent analysis of Abitibi
targeting shows a very strong correlation with Panther's targets
identified from soil geochemical sampling. The highest
priority Abitibi CET and EM targets are located directly below or
in close lateral proximity to very anomalous base metal, PGE and Au
in soil results, reinforcing and prioritising the associated
drilling targets (Figure 3).
Five of the CET targets coincide
with an ultramafic intrusive body modelled directly below Lampson
Lake. Significantly, government regional lake sediment sampling
work was shown that Lampson Lake contains highly anomalous 985 ppm
copper together with anomalous Cd, Co, Sn ,W, Y and heavy rare
earth elements ("REEs"). The presence of anomalous REEs in the lake
sediment is favourable and may be indicative of hydrothermal
alteration. Anomalous levels of REEs in lake sediment are spatially
associated with the hydrothermally altered rocks near the Winston
Lake Cu--Zn deposit in the Schreiber greenstone belt.
The airborne electromagnetic and
magnetic data alone leaves a level of uncertainty as to the
position of possible sulphide lenses. The presence of anomalous
nickel, cobalt and base metals in the soils may also be related to
disseminated sulphides that do not produce a significant EM
response in which case drill testing results will provide support
to follow-up survey work such as deep-targeted induced polarisation
ground geophysics to detect massive or disseminated sulphides at
depth.
Due east of the Dotted Lake project,
on a neighbouring property, GT Resources Inc. have drill
targeted ultramafic feeder dykes coincident with soil anomalies,
leading to multiple discoveries of high-grade nickel and copper and
PGE. Preliminary interpretation suggests that the Dotted Lake
ultramafic intrusive complex is part of the same mineralising
system.
Geological
Setting
The Dotted Lake project is located
upon the north-eastern end, constituting the northern limb, of the
Schreiber-Hemlo Greenstone Belt (the "Belt"), in the Abitibi-Wawa
sub-province of the Superior province of the Canadian Shield. All
rocks are of Archaean age (2.7 billion years old), except for the
Proterozoic diorite dykes.
The primary rock type of the Belt is
mafic volcanics, felsic and intermediate volcanic rocks and
clastics overlie these mafic volcanics and the belt is intruded by
numerous felsic granitoids. The south-eastern sector of the Project
area is bounded to the south by a biotite leucogranodiorite
intrusive body constituting the Dotted Lake batholith. These
intrusive rocks are pink in colour, foliated and medium grained,
and appear to intrude both the metavolcanics and mafic/ultramafic
rocks.
Several stages of regional folding
have occurred in the Belt, the latest stage is the most pervasive
and occurred contemporaneous to, or predated, the intrusion of the
Dotted Lake batholith.
The predominant rock type in the
centre and south-western quadrant of the Project area is foliated,
fine grained, dark green, amphibole rich metavolcanic rock. Medium
and coarse grained amphibolites are less common and occasional
remnant pillow textures have been observed indicating a submarine
depositional environment. Small sills and dykes of granitoid rocks
are common in the volcanic rocks.
The Project area displays NW-SE
oriented faults and Matachewan mafic dykes, N-S oriented Marathon /
Kapuskasing dykes, and NE-SW oriented faults/shear
zones.
The north-eastern portion of the
Project area contains a mafic and ultramafic intrusive complex of
gabbro, peridotite and serpentinised peridotite intruded along the
southern flank of the mafic volcanics. This ultramafic intrusive
complex presents a significant target area for nickel, cobalt,
copper and PGE sulphide deposits, which constitute an important
source of critical minerals.
The Project is also prospective for
lode-gold mineralisation particularly in zones of structural
complexity (where faults, shears, deformation, and feeder dykes may
be present) and in the deformed zones peripheral to the Dotted Lake
batholith.

Notes to Editors
Panther Metals PLC is an exploration
company listed on the main market of the London Stock Exchange.
Panther is focussed on the discovery of commercially viable mineral
deposits. The Company's operational focus is on established mining
jurisdictions with the capacity for project scalability. Drill
targets are assessed rapidly utilising a combination of advanced
technologies and extensive geological data to decipher potential
commercial viability and act accordingly. Panther's current
geological portfolio comprises of three highly prospective
properties in Ontario, Canada while the developing investment wing
focuses on the targeting of nickel and gold in
Australia.
Obonga Project
Panther Metals acquired the Obonga
Greenstone Belt in July 2021 and have already identified five
prospective primary targets: Wishbone, Awkward, Survey, Ottertooth
and Silver Rim. A successful Phase 1 drilling campaign at Wishbone
in Autumn 2021 revealed the presence of significant VMS-style
mineralised systems on the property - the first such discovery
across the entire greenstone belt. Intercepts include 27.3m of
massive sulphide in hole one, and 51m of sulphide-dominated
mineralisation in hole two. Both drill holes contained multiple
lenses. Anomalous high-grade copper in lake sediment close to the
target area has also been identified, increasing confidence in the
prospectivity of the location.
Awkward is a highly anomalous
magnetic target, interpreted to be a layered mafic intrusion and
magmatic conduit based on mapped geology and airborne geophysics.
Historic sampling in the area returned anomalous platinum and
palladium (Pt, Pd) values, while historic drilling on the periphery
of the target intersected non-assayed massive sulphide and copper
(assumed to be chalcopyrite), non-assayed disseminated pyrite and
chalcopyrite in coarse gabbro, and non-assayed 'marble cake' gabbro
(matching the description of the Lac des Iles Mine varitexture
gabbro ore zone).
Two additional named targets, Survey
and Ottertooth, both displays further coincident magnetic and
electromagnetic anomalies and are adjacent to the contact between
intrusive and extrusive mafic rocks. Historic drilling at Survey
intersected several meters of massive sulphides in multiple
intersections (main parts of the anomaly remain untested) while
Ottertooth remains untested in its entirety.
Dotted Lake Project
Panther Metals acquired the Dotted
Lake Project in July 2020, it is situated approximately 16km from
Barrick Gold's renowned Hemlo Gold Mine. An extensive soil
programme conducted in 2021 identified numerous gold and base metal
targets, all within the same geological footprint. Following the
installation of a new trail providing direct access to the target
location, an initial drilling programme in Autumn 2021 confirmed
the presence of gold mineralisation within this system with
anomalous gold continuing along strike and present within the
surrounding area.
Fulcrum Metals Plc
Fulcrum Metals PLC (LON: FMET) is an
AIM listed exploration company which finances and manages
exploration projects focused on Canada, widely recognised as a top
mining jurisdiction.
FMET currently holds a beneficial
100% interest in highly prospective gold and base metals projects
in Ontario and Uranium projects in Saskatchewan.
Fulcrum's strategy is to focus on
discovery and commercialisation of its Projects through targeted
exploration programmes. The primary focus is to make an economic
discovery on the flagship Schreiber-Hemlo Properties and
establishing the prospectivity of its wider Ontario and
Saskatchewan portfolio with a view to securing potential joint
venture and/or acquisition interest.
Panther Metals Plc own 15% of the
issued share capital of Fulcrum Metals Plc and a 2% NSR on the Big
Bear project.
Panther Metals Australia
Following the listing of Panther
Metals' Australian assets on the Australian Securities Exchange
("ASX") in December 2021. The ASX listing has provided the
Australian projects with the necessary capital to advance
drill-ready targets focused on nickel and gold (within the Tier 1
Mining Districts of Laverton WA and in the NT). Through this
spin-out Panther holds an attractive investment prospect, without
any disruption to the Company's capital structure and without any
financial obligations.
Conclusion
Panther Metals understand that the
commercial realities of building an exploration company requires
expertise in geology, finance, and the markets within which they
operate. The Company's extensive network of industry leaders allows
it to meet these objectives. Ultimately however, drilling success
is the only route to discovery: the fundamental objective of any
exploration company. Once Panther's world-class geological team
identify the anomalies, they work hard to get drilling. The drill
hole is the only place where substantial and sustained capital
growth originates and it's with that operational focus Panther
Metals will continue to advance.
