Western Gold's MT Survey Confirms Depth
Potential for Mineralised Copper-Gold
Porphyries in Lorne, Scotland
North Berwick, Scotland--(Newsfile Corp. - November 4, 2024) -
WESTERN GOLD EXPLORATION
LTD. (TSXV: WGLD)
(the "
Company
") is pleased to announce the results of its 779-line km helicopter
magnetotelluric (MT) geophysics survey within the Lorne Porphyry District, Argyll, Scotland. The survey
demonstrated strong depth and near-surface potential at both Lagalochan and Ardlochan prospects and
identified other possible porphyry-related centres across the Company's Crown Mines Royal License.
This is the first time worldclass MT technology with depth penetration up to 1.5km has been used within
the United Kingdom.
"We are excited by the results which clearly demonstrate an association between known porphyry
mineralisation and geophysical anomalies, confirming scope to extend to depth and along strike. The
survey indicates a developing porphyry district with numerous untested anomalies,"
commented Harry
Dobson, Chairman.
Results
Lagalochan
Existing drilling (totalling 11,090m over 56 holes, which includes LD13-01A: 537m @ 0.18% Cu,
0.1 g/t Au from 2m) shows mineralisation follows a conductivity-resistivity anomaly and extends
significantly along a northwest-trending zone, suggesting porphyry mineralisation is more
widespread than previously tested (
see Figure 1 and
N1 43-101 Technical Report on
Lagalochan
on the company's website).
Conductivity increases below the depth of existing drilling, potentially indicating that porphyry
sulphide mineralisation is also strengthening at greater depths.
The Company's 2023-2024 drilling campaign intersected a sulphidic breccia which appears highly
conductive in the survey (
see Figure 2
), indicating a second breccia/skarn target type parallelling
the main porphyry zone has yet to be explored.
Ardlochan
A 'classic porphyry' ring structure has been identified at Ardlochan (
see Figures 1 & 3
),
characterised by a conductive ring centred on a resistive core.
Recent shallow drilling that intersected porphyry style copper gold mineralisation appears to
have been sited above and marginal to the conductive ring structure (
see Figure 3
), adding
significance to the geophysical anomaly.
A magnetic-high overlaps central sections of the ring structure and is situated near previous drilling
(c. 125m horizontal), which identified primary bornite-magnetite mineralisation and represents a
hypogene porphyry core target zone.
Possible New Porphyry Centre Identified
A new target zone consisting of a circular resistivity high concealed beneath c.200m of cover has
been identified several kilometers NW Lagalochan (
Figure 1
).

Lagalochan
The primary goal at Lagalochan was to explore below current drilling, examining the potential for
porphyry mineralisation at depth. Lagalochan is marked by a strong phyllic alteration assemblage which
overprints primary potassic alteration to depths of c. -400m.

system at depths below historic drilling. The high-conductivity skarn-breccia target has been
intersected near-surface during 2023-2024 drilling. The Main Porphyry target follows the resistivity-
conductivity gradient that extends NW-SE.

A resistivity-slice taken -400m RL, below the level of copper-destructive phyllic alteration is displayed in
Figure 2
.
The main North Hill mineralisation lies on the margins of a resistive lobe, along a resistivity-
conductivity gradient that covers the northern extent of the Red Feldspar Porphyry (RFP) that is host to
the North Hill porphyry mineralisation (
Figure 1 & 2
). The resistivity-conductivity gradient itself trends
NW-SE (
Figure 2
) beyond the margins of historic drilling, suggesting mineralisation could significantly
extend beyond the previously recognised North Hill zone.
By -500m RL (
Figure 1 & 2
), which is beyond the deepest drillhole, conductivity increases markedly,
suggesting that fluid flow, alteration and mineralisation is increasing marginal to North Hill porphyry
mineralisation and thus the primary mineralisation in the contact with the resistive horizon is likely to have
concomitantly increased. The anomaly continues strongly to at least -700m RL (around 1km below
surface) where the survey starts to lose definition, but the anomaly continues.
The high conductivity zone was encountered during the Company's 2023-2024 drilling as:
1)
a bleached,
argillically altered breccia pipe with extensive pyrite matrix and
2)
an epidote-Kspar-pyrite bearing skarn,
both of which contained zones of anomalous gold (0.1-1.5 g/t Au) enrichment (see company press
release dated 2
nd
May 2024) and are strongly depleted in copper. Given the copper depth zonation
observed within many porphyry-breccia systems, this adds another target type to the exploration
potential of Lagalochan.

A 'classic porphyry' ring structure has been identified at Ardlochan, characterised by a highly conductive
ring centred on a resistive core (
Figure 3
). The ring structure sits beneath a resistive cap and begins to
develop at +100m RL only 250m below surface and is spatially coincident with a magnetic-high anomaly
(
Figure 3
). The Company's winter 2023-2024 drilling drilled above the southern margins of the ring
structure and did not reach the level where the conductive ring starts to develop (
Figure 3
) but did
encounter porphyry style mineralisation from surface (see company press release dated 2
nd
May 2024).
By analogy to Lagalochan, core potassic porphyry mineralisation should be inboard of this conductive
ring zone, remains undrilled, and represents a strong drill target at relatively shallow levels.
Magnetite and bornite mineralisation were noted for the first time together in drill core at Ardlochan,
strengthening the idea that the combined magnetic resistivity zone could represent hypogene porphyry
mineralisation, hidden beneath a shallow intrusive cap.
Survey Details
The MT survey was conducted by Expert Geophysics (EGL), a Canadian specialist contractor, between
the 16
th
- 23
rd
of August 2024 using a low flying helicopter with full permission of the Civil Aviation
Authority.
The survey covered 779 line-km over a 96km
2
area of the Company's Inverliever Crown Lease area
(Figure 1).
Lines were at 200m spacing with 100m infill lines over areas of known mineralisation at an
orientation of N 22° E. This orientation was chosen to negate the effects of the highly magnetic late
tertiary dykes which mask the weaker magnetic signatures of the Dalradian country rocks and the
Silurian Lorne intrusive complex which hosts the porphyry mineralisation.
The electromagnetic (EM) system utilised was enclosed within a blimp-like casing and suspended from
a tow-wire, alongside a separate magnetometer unit. The average terrain clearance of the EM blimp
was 81m above land-surface.
