SOMA GOLD Extends Copper Soil Anomaly BY 2.5 Km, Bringing the Total Strike to 4.5KM
SOMA GOLD EXTENDS COPPER SOIL
ANOMALY BY 2.5 KM, BRINGING THE TOTAL
STRIKE TO 4.5KM
VANCOUVER, BC
,
Nov. 18, 2025
/CNW/ -
Soma Gold Corp.
(TSXV: SOMA) (WKN: A2P4DU)
(OTC: SMAGF) (the "
Company
" or "
Soma
") is pleased to provide an update on the ongoing soil
sampling program at its Psyche 2 target area within the Machuca Project in Antioquia,
Colombia
(Figure 1). Psyche 2 was initially identified through high-grade stream sediment samples and the
presence of informal, small-scale mines (see news release dated
October 24, 2024
). The Company
has since expanded the soil sampling program northward along a prominent, linear, north-south-
trending magnetic high that coincides with a recently identified copper-in-soil anomaly (see news
release dated
May 6, 2025
). This release presents results from an additional 510 soil samples.
Soil Sampling
An additional 510 samples, bringing the total to 1,394, were collected to extend the Psyche 2 soil
grid completed in early 2025. The samples were collected at
50 m
intervals along lines spaced
200
m
apart, covering the entire strike extent of a north-south trending magnetic anomaly. Fire assay
results and multi-element geochemistry have been received for 1,291 samples, with multi-element
results pending for the remaining 103. The previously discovered high copper-in-soil values extended
over the entire length of the magnetic anomaly, adding 2.5 km of strike length to the copper anomaly
for a total strike length of approximately 4.5 km (Figure 2). The average width of the anomaly is
325
m
.
Copper concentrations range from 2.5 ppm to 795 ppm. The 97.5
th
percentile values range from 336
ppm to 795 ppm, while the 95
th
and 90
th
percentile values are 291 ppm and 212 ppm, respectively.
Table 1 presents the 95
th
percentile copper values and highlights a relationship between weakly
anomalous gold and zinc values. Highly anomalous gold and zinc soil samples occur in clusters along
the trend of the magnetic anomaly.
Gold concentrations in the soil samples range from <5 ppb to 7,605 ppb (i.e., 7.6 g/t Au). The 97.5
th
percentile values, ranging from 90 ppb to 7,605 ppb, are considered strongly anomalous. The 95
th
and 90
th
percentile gold values are 55 ppb and 37 ppb, respectively. The 97.5
th
percentile values
commonly correlate spatially with known high-grade quartz veins in surface outcrop or informal mines
and are interpreted to reflect the presence of gold-bearing quartz veins. Lower, yet still elevated,
gold-in-soil values along the strike of the known quartz veins are interpreted as evidence of the
continuity of these gold-bearing structures. Table 2 presents the 97.5
th
percentile soil sample results
across the grid.
Chris Buchanan
, Soma's Vice President of Exploration, stated, "Discovering the continuation of the
copper anomaly to the north of the Rio Pocune is an important development for the Psyche 2 target.
Our team has been mapping and prospecting to determine the geological nature of this significant
soil anomaly. We are looking forward to initiating the maiden diamond drill program further to
investigate the underlying geology of the soil anomaly."

Figure 2 displays the copper-in-soil values superimposed on the first vertical derivative map of the
recently flown magnetic survey (see news release dated
February 6, 2025
). The 95
th
percentile
copper values are clustered along the western edge of the soil grid, forming a north-south trending
anomaly with a strike length of approximately 4.5 kilometres. This anomaly is located near the
Otú Fault and is interpreted to be controlled by associated higher-order structures. The anomalous
copper samples also coincide with a prominent magnetic high. The cause of the magnetic high is
currently unknown, and geological mapping is underway along the entire length of the anomaly to
determine the nature of the underlying bedrock. However, mapping is hampered by poor exposure
due to dense vegetation and thick saprolite cover.

Figure 3 displays the gold-in-soil values superimposed on the first vertical derivative map of the
magnetic survey. Solid and dashed red lines indicate the mapped and interpreted vein traces in the
area. All identified informal mines coincide with gold-in-soil anomalies. The strike length of these gold
anomalies and associated quartz veins ranges from 300 to 1,000 meters. These findings are
considered significant and warrant follow-up prospecting, infill soil sampling, and drilling near the
informal mines.

Figure 4 presents the zinc (Zn) values, which form a distinct trend that is coincident with the copper
and gold anomalies along the western edge of the soil grid. Figures 5 and 6 display the anomalous
values for nickel (Ni) and cobalt (Co), which are also coincident with the Cu and Zn anomalies along
the magnetic high. Additional elements commonly used as indicators of gold mineralization systems
are also present in the area, forming distinct trends associated with gold anomalies. On the eastern
side of the soil grid, several elements are strongly anomalous, including arsenic (As), molybdenum
(Mo), mercury (Hg), and antimony (Sb) (see figures 7-10). The most anomalous samples are
generally coincident with the gold anomalies and known high-grade gold-bearing quartz veins.
Soil sampling has successfully identified numerous gold anomalies at the Psyche 2 target. The extent
and tenor of the copper anomaly represent an exciting new exploration target in the region. A drilling
campaign in late 2025 will determine the geology of the host rocks and the style of potential copper
mineralization. The copper anomaly remains open to the north and south along portions of the
magnetic high that have not yet been soil sampled. Soma will continue expanding the soil grid to
define the full extent of the copper and gold anomalies. Drilling operations will also continue at the
high-grade gold targets near the Colossa Mine and the Aurum-Orion-Eros area while the Company
awaits approval of drilling permits for the copper anomaly.
The Psyche 2 gold target area is a 2.4 km long, northeast-southwest-striking trend of mineralized
quartz veins, with a width of approximately 300-
400 m
. The target is located east of the Otú Fault, in
a region predominantly underlain by undifferentiated upper-greenschist-facies metasedimentary
rocks (Figure 2). The rocks are strongly folded, exhibiting north-south-trending axial planes and
moderately northeast-plunging fold axes. However, the fold system is only exposed in a few small
creek outcrops and remains poorly constrained. The far eastern edge of the property is also poorly
exposed, but underlain by a strong regional magnetic signature like the magnetic signature of the
Segovia Batholith and is interpreted to demarcate the western contact of the batholith in this area.
Unlike other quartz veins and informal mines along the Otú Fault, these veins have an average
orientation of 240
o
/43
o
, forming a high angle relative to the northerly trending Otú Fault and are
similar to the orientation of Aris Mining's (TSX:ARIS) El Silencio vein in Segovia. The quartz vein
orientation also aligns with a regional lineament trend, suggesting the potential for additional quartz
vein-bearing structures along the same trend. Mapping within informal mines has identified two
additional sets of mineralized quartz vein orientations: east-northeast- and north-striking. In general,
the veins dip moderately to the northwest.
The Otú fault system ("Otú Fault") extends for over 100 km, from Segovia-Remedios in the south to
Nechi in the north, where it is buried beneath younger sedimentary overlap sequences. Soma's
tenements now cover more than 56 km of this strike length. High-grade gold deposits have been
identified along the entire length of the Otú Fault, hosted in brittle-ductile to brittle quartz veins
formed during later deformation stages. Throughout the district, quartz veins show orientation
patterns consistent with formation in conjugate faults associated with brittle faulting along the Otú
Fault. Notable mines along this trend include Segovia-Remedios, La Aurora, El Limon,
Le Ye
, Los
Mangos, and Cordero. The Machuca Property is located along a key segment of this regional fault
system and shows numerous signs of high-grade gold mineralization.
Soil sampling and QA/QC protocols
Soil samples are collected on a predetermined grid, typically with
50m
spacing along
200 m
-spaced
lines. The sampler digs a pit to expose the C-horizon of the local soil profile. A 2.0 kg sample is
extracted from the C-horizon and submitted to the laboratory for analysis. Additional information
regarding the stratigraphy of the soil profile, depth of the C-horizon, and a description of the
sampled material is recorded by the sampler.
All soil samples for Soma Gold are submitted to ActLabs Medellin for sample preparation and
analysis. All samples are dried and sieved prior to analysis at the lab. A 50-gram aliquot fire assay
with an atomic absorption finish determines gold and silver values. An aqua regia digestion and ICP-
MS analysis is used to determine the concentration of a 36-element package.
QA/QC is monitored using field duplicates, blank material, and certified standard material (CRM).
The CRM is purchased from OREAS.
