SARAMA RESOURCES OUTLINES EXTENSIVE
GOLD TRENDS AT COSMO GOLD PROJECT
Kilometre-Scale Gold Trends Delineated by Large-Scale Soil Geochemistry Program
Highlights
PERTH, AUSTRALIA / VANCOUVER, CANADA . Sarama Resources Ltd (“ Sarama” or the “ Company”) (ASX:SRR, TSX-
V:SWA) is pleased to announce that several large trends of gold anomalism have been delineated by the recently
completed regional soil geochemistry survey at its Cosmo Gold Project (the “Project”)(1,2) in the Laverton Gold District
of Western Australia (refer Figure 1).
The results are the product of the first significant and systematic exploration program conducted on the belt -scale
project and the Company is encouraged by the scale of the anomalism and strength of targets delineated . The
anomalous trends , which extend in aggregate for approximately 45km with individual strike lengths up to
approximately 7km, are located in a range of litho-structural settings, illustrating the geological diversity of the Project
and its potential to host multiple styles of gold mineralisation .
Sarama’s Executive Chairman, Andrew Dinning commented:
“We are very encouraged by these early results, which represent a strong start to our exploration at the Cosmo Gold
Project. The scale and number of gold anomalies highlight the Project’s potential and aligns well with our broader
strategy to unlock value across our 1,000km² (1,2,3) landholding in the highly prospective Laverton Gold District. These
results help refine our exploration focus and provide a solid foundation for prioritising key targets and planning the
next phase of work, including targeted geochemistry and reconnaissance drilling .”

Extensive Gold-in-Soil Anomalism Delineated
The regional soil geochemistry program has successfully delineated numerous zones of extensive gold -in-soil
anomalism that provide an immediate focus for future exploration within the Project’s large 580km² footprint. These
gold-in-soil trends are noteworthy given their continuity, coherence and strike extent.
At a high level, several clusters of elevated gold zones can be identified within the global raw assay data (refer Figure
2). These clusters can be interpreted to lie at the intersection of 4 belt-scale lineaments, presumed to be faults or
other structural features , generally trending in approximately orthogonal orientations . The north -western trends
broadly align with the regionally significant Sefton Shear Zone ; these spatial associations are encouraging and give
insight into controls on gold-bearing fluid flow and emplacement throughout the greater Project.
Interpretations of anomalous zones at a prospect level have successfully identified 8 key prospect areas featuring
extensive gold-in-soil anomalism which provide an immediate focus for exploration work (refer Figure 3). Delineation
of anomalous trends considered the continuity of grouped sample values and interpreted geological, structural and
topographical features . T he statistical significance of the gold assays in the context of regolith domains was also
considered and in general, a 90th percentile gold value threshold was adopted.

Ironbar Prospect
The Ironbar Prospect hosts two trends of kilometre-scale anomalism that intersect in the immediate vicinity of the
Sefton Shear Zone (refer Figure 4). These trends are broadly defined by +5ppb Au soil sample values (corresponding
to the 90th percentile) and are interpreted to extend for strike lengths of 3.8km and 2. 0km in orientations of north -
north-east (“NNE”) and north-west (“NW”) respectively. The intersection area of the trends contains elevated gold -
in-soil values (+10ppb Au) covering a footprint of approximately 600m x 600m with a peak sample value of 20ppb Au.
The high tenor anomalous zone was sampled in sand y cover material and interpretations suggest the intersection of
the 2 anomalous trends lies over the contact of an ultramafic unit with a mixed mafic volcanic unit to the east.
Airborne magnetic imagery shows a number of subtle magnetic disturbances underlying the Ironbar Prospect,
suggestive of NE-trending faults and a small-scale intrusion.

Warrior-Rockatansky-Pappagallo Prospects
The combined Warrior-Rockatansky-Pappagallo Prospects host several NW-trending anomalous zones within a trend
strike length of approximately 7km (refer Figure 5). The zones are broadly defined by the 90th percentile gold values
within covered and sub-crop domains and are coincident with interpreted mafic and ultramafic volcanic units, which
are bounded by a regional granite-gneiss terrane to the west and the late- stage Cosmo Mesogranite unit to the east.
Importantly, the NW trend of mineralisation is spatially associated with the belt -scale, NW -trending Sef ton Shear
Zone.
In the central and southern part of the anomalous trend , several higher tenor zones (+10ppb Au) are present with
continuity traced for approximately 4. 5km. These potentially reflect bedrock gold mineralisation and Sarama is
particularly encouraged by their spatial association with the volcanic/intrusive contact and anomalous magnetic
features. Extensive anomalism is also observed in areas overlain by cover, which is significant given the prevalence of
sandplain material over the Project. The anomalous trend includes the Project’s peak gold value of 94ppb Au .

Cheedo-Humungus-Zanetti Prospects
The combined Cheedo-Humungus-Zanetti Prospects host extensive gold -in-soil anomalism in cover and sub- crop
material along two main trends defined by 90th percentile values (refer Figure 6).
A north-east (“NE”) trend extends for approximately 7km and has a footprint up to 1.8km in width with gold values
up to 80ppb Au. The broad trend is hosted in a complex regolith setting and some mechanical dispersion of gold from
historical small-scale workings has likely occurred in the area and been the subject of shallow ( generally <5m) stab
holes in rotary -air-blast (“RAB”) drilling. T he trend is coincident with disrupt ed features in magnetic imaging which
suggests an association with a structural feature transgressing the volcanic and intrusive units in the immediate area
of the anomalism. Ground truthing and further analysis will assist in refining the interpretation and target definition.
A secondary NW -trending anomalous gold zone within the Cheedo Prospect has been interpreted to extend for a
strike length of 2.8km in an extensive sandplain area with a peak gold value of 12ppb Au. The anomalous zone is co -
incident with the contact of interpreted mafic volcanic and ultramafic rocks in the vicinity of the regionally extensive
Sefton Shear Zone. The primary 7km-long NE-trending zone is proximal to this secondary zone and the associated
disruptions to magnetic features are also present.

Toecutter Prospect
The Toecutter Prospect hosts two broad anomalous zones extending up to 2.6km in length and 1.4km in width (refer
Figure 7) . The anomalism occurs largely within sandplain material and contains a peak value of 21ppb Au . The
anomalism is located on the northern edge of the interpreted Cosmo Mesogranite unit which may play an integral
role in the emplacement of gold mineralisation. This broad contact zone of the granitic unit and the adjacent volcanic
rocks is considered a prospective area for gold mineralisation and it is encouraging that this type of target has been
identified by the recent survey given the regolith setting and complex sampling medium.

Next Steps
Sarama is encouraged with early-stage exploration on the Project to date , particularly with the continuity and extent
of the key areas of gold -in-soil anomalism and their general correlation with underlying interpreted geology and
structural features.
The soil geochemistry program has highlighted extensive areas of elevated gold -in-soil anomalism that the Company
intends to ground truth and plan further infill soil grids around. In addition, planning will commence for
reconnaissance drilling in the high-priority areas for which existing soil geochemistry sample density is sufficient for
drill targeting.
The recent survey also highlight s anomalous zones in unexpected areas that require follow -up including further
fieldwork, desktop investigation and potential re -sampling, all of which will be undertaken in parallel with work on
the primary targets.
Soil Sample Collection and Analytical Methodology
The majority of the soil geochemistry program was conducted during Q4 2024 - Q1 2025 and was designed to cover
broad areas of the 580km² project area as a foundational stage in drill target generation (refer Figure 8). Grids of 400-
800m x 100m oriented east -west were employed for the bulk of the program with sampling of high priority areas
conducted on 200m x 100m spacing. In total, samples were taken from approximately 5,000 sites within target areas
generated from geophysical surveys and historical ad-hoc exploration works.
Samples were collected at depths of 10 -20cm across the P roject using a shovel and sieved in the field to produce a
minus 0.9mm sub-sample. LabWest’s Ultrafine+TM process was used to further sub-sample this material to produce a
final minus 2 micron fraction for multi-element grade determination using aqua regia digest and spectral analysis. For
each sample, a total of either 65 or 53 element values were reported, depending on commodities targeted by
exploration.
