WCE–Falcon Metals JV Reports
12m @ 2.8g/t Gold at Errabiddy
• Falcon Metals Limited (ASX: FAL) reports 12m @ 2.8g/t gold (downhole) from
surface, including 4m @ 4.7g/t gold, in its first reverse circulation drill hole
(OWRC0001) at Olsen Well1
.
• Olsen Well is within WCE-owned Exploration Licence E09/2457. Falcon holds
a right to earn a 70% interest in that tenement (excluding graphite rights);
WCE is free-carried for Falcon’s exploration expenditure under the current
earn-in arrangement2
.
• The result is from the first of five holes assayed. Four widely spaced holes to
the west returned no significant intersections; follow-up drilling is required
to determine the orientation and continuity of mineralisation.
• Falcon has expanded drilling to 7,000m. At 19 October 2026, 35 holes for
4,556m had been completed, with assays pending for the remaining 30 holes.
• WCE retains exposure to the Errabiddy Gold Project and separately holds
100% of the prospective Parrot Bore (E09/2602) and Parrot Bore East
(E09/2652) tenements, which have previously identified gold geochemical
anomalism3
.
• The encouraging Olsen Well result supports further evaluation of the broader
area's gold prospectivity, including WCE's Parrot Bore and Parrot Bore East
tenements.
West Coast Silver Limited (ASX: WCE) ('West Coast Silver' or the 'Company') is pleased to report
encouraging initial gold drilling results announced by farm-in and joint venture partner Falcon Metals
Limited (ASX: FAL) (“Falcon”) at the Olsen Well prospect, located within WCE's wholly owned
Exploration Licence E09/2457, part of the broader Errabiddy Gold Project in Western Australia.
Commenting on FAL’s Results at Olsen Well, CEO Sergei Smolonogov said:
“We congratulate our JV partner, Falcon Metals on an encouraging start to its maiden drilling campaign
at Olsen Well. The initial results highlight the benefits of our farm-in partnership, providing West Coast

The results also reinforce our confidence in the broader Errabiddy Project, where WCE retains 100%
ownership of the prospective Parrot Bore tenements E09/2602 and E09/2652. Historical exploration
identified gold and copper soil anomalism across the area, including a 600m × 600m copper–gold
anomaly at Parrot Bore within E09/2602.4
.
We look forward to Falcon's ongoing drilling results and will continue evaluating opportunities to
advance exploration across our 100% owned Errabiddy tenements.”
FALCON DRILLING RESULTS
Falcon reported that its first drill hole at Olsen Well, OWRC0001, returned 12m @ 2.8g/t Au from 0m,
including 4m @ 4.7g/t Au from 0m. The mineralised interval was reported from four-metre composite
samples. One-metre primary samples that make up the composites are planned for individual re-assay.
This was the first drill testing of the 5.8km-long gold-in-soil anomaly at Olsen Well.
Assays have been received for five holes. Four wide-spaced holes located approximately 200–400m
west of OWRC0001, returned low-level gold anomalism but no significant assay values for gold. The
orientation, extent and continuity of the gold mineralisation remain to be established.
As reported by Falcon on 19 October 20265
, 35 reverse circulation holes totalling 4,556m had been
drilled. Assays are pending for a further 30 holes. Falcon has expanded its program to 7,000m to test the
mineralised zone along strike and at depth.
WCE / FALCON JV – PROJECT OVERVIEW
The WCE / Falcon JV is located approximately 200 km northwest of Meekatharra in Western Australia.
The Errabiddy area is a structurally complex setting at the north-western margin of the Yilgarn Craton.
The wider exploration strategy targets orogenic gold and intrusive-hosted nickel–copper mineralisation
through geological mapping, geophysics and targeted drilling6

WCE OWNERSHIP AND EARN-IN EXPOSURE
West Coast Silver owns 100% of Exploration Licence E09/2457, which hosts the Olsen Well prospect.
Under the farm-in and joint venture agreement announced on 27 November 2024, Falcon has the right
to earn up to a 70% interest in the tenement, excluding graphite rights, which remain 100% owned by
WCE. Falcon is funding exploration activities as part of its earn-in obligations at no cost to WCE,
providing theCompany with exposure to explorationsuccess without directly funding thecurrent drilling
program.
WCE retains 100% ownership of the adjoining Parrot Bore and Parrot Bore East tenements, which form
part of its broader Errabiddy exploration portfolio and have previously identified gold geochemical
anomalism. Falcon's encouraging initial drilling results at Olsen Well provide further evidence of the
regional gold prospectivity and support continued assessment of underexplored WCE-owned
tenements, which have yet to be drill tested.
NEXT STEPS
Falcon is undertaking follow-up drilling around OWRC0001, with further assay results pending. WCE
will review these results as they become available and assess their relevance to its broader Errabiddy
tenement portfolio. In light of Falcon's encouraging initial results, WCE is re-examining the historical
Au-Cu soil anomalism at Parrot Bore to assess opportunities for targeted follow-up exploration and the
potential identification of drill-ready targets.

ASX / Media Announcement
19 October 2026
First Hole at Errabiddy Hits 12m @ 2.8g/t Gold from Surface
• Assays received for the first five RC drill holes completed at Olsen Well at the Errabiddy
Gold Project, with the first hole intersecting:
OWRC0001 12 metres @ 2.8g/t gold from surface; including
• 4 metres @ 4.7g/t gold from surface
• Confirms a high-grade bedrock source to the previously defined extensive soil and rock-
chip gold anomaly, which extends over 5.8 kilometres of strike
• The remaining four holes, which tested the broader soil anomaly 200-400m west of
OWRC0001, returned low-level anomalism, with additional drilling planned to adequately
test this area
• Olsen Well prospect is ~35 kilometres southeast of Benz Mining’s (ASX: BNZ) Glenburgh
Gold Project
• Drilling is currently focused on defining the extent of the mineralised structure with the
program expanded to 7,000 metres
• Assays are pending for a further 30 completed holes
Falcon Metals Limited (ASX: FAL) (“Falcon” or “the Company”) advises it has received assay results for
the first five reverse circulation (RC) drill holes at Olsen Well, a large greenfield craton-margin gold
prospect within the Errabiddy Gold Project in Western Australia. The Project is approximately 35
kilometres southeast of the Benz Mining (ASX: BNZ) Glenburgh Gold Project (see Figure 1).
This program is the first-ever drill testing of Olsen Well which is a 5.8km long gold-in-soil anomaly.
Drilling is focused on the central 2.5km-long zone of >25ppb gold-in-soil anomaly within the broader
5.8km-long >10ppb anomaly. The central area of the anomaly includes soil values of greater than 1g/t
gold.
The first drill hole, OWRC0001, drilling into the highest-grade part of the soil anomaly, returned
12 metres @ 2.8g/t gold from surface, including 4 metres @ 4.7g/t gold from surface. Samples were
taken as 4 metre composites, with the 1 metre splits from this interval to be submitted for assaying.
Four additional wide-spaced holes 200-400 metres west of OWRC0001 returned low-level anomalous
results, however additional drilling is planned to further evaluate this target area, as at this stage,
nothing is known about possible orientations and structural controls on the gold mineralisation.
Follow-up drilling is also underway to better define the extent of the zone intersected in OWRC0001,
targeting extensions along strike and at depth. The program has been expanded to 7,000 metres.
Assays are currently pending for a further 30 completed drill holes.
Falcon Metals’ Managing Director Tim Markwell said:
"Intersecting 12 metres at 2.8g/t gold from surface in the first hole drilled at Olsen Well is an exciting
start to the program at Errabiddy. The result confirms that the strong surface geochemical anomaly
reflects bedrock gold mineralisation and provides confidence in the prospectivity of the target. We
have immediately expanded the program to 7,000 metres to test the extent of this mineralisation.
With drilling continuing and additional assays pending for a further 30 holes at this stage, we are now
focused on understanding the geometry of the mineralisation and evaluating its broader scale
potential."

DRILLING RESULTS
The maiden EIS co-funded drilling program at Olsen Well is progressing, with 35 holes completed for
4,556 metres (see Figure 2). The initial assay submission from the first five holes was prioritised to
assess bedrock mineralisation while the drill rig remained on site.
The first hole, OWRC0001, intersected 12 metres @ 2.8g/t gold from surface, within joint-oxidised
biotite-quartz-feldspar gneiss with minor quartz veining (see Figure 3 for cross section of OWRC0001
and Figure 4 for the chip tray with grades).
This hole was collared at the peak of the Falcon defined soil anomaly, coincident with a 30-metre-wide
zone of anomalous bedrock where four rock chip samples returned >1g/t gold, including a peak of
6.4g/t gold (See ASX Announcement dated 27 July 2026 ‘Green Light for Drilling at Errabiddy Gold
Project’). Low-level gold anomalism continues below the mineralised interval, averaging 44ppb gold
from 12–68 metres, providing a broader geochemical footprint that will be assessed as drilling
progresses. Follow-up drilling at this site was deferred to allow additional earthworks, including the
construction of larger sumps to manage higher-than-expected groundwater inflows.
The four subsequent holes with assay results were testing the western and southern margins of the
>50ppb gold-in-soil anomaly, 200-400m west of OWRC0001, and returned no significant intercepts,
although zones with low-level gold anomalism were identified, with a zone of 33ppb gold from 80-108
metres in OWRC0003. Additional drilling to test the remainder of the soil anomaly between these
holes and OWRC0001 is planned to determine the dip, strike and continuity of the mineralisation.

The geological logging of the Olsen Well prospect has identified highly deformed gneissic and
amphibolitic rocks, including felsic orthogneiss and biotite-to-white-mica-rich paragneiss, with local
pegmatitic segregations and less deformed dolerite dykes and gabbros. Quartz veining, silicification
and variable pyrite have also been observed, although their relationship to gold mineralisation
remains to be established once further assay results are received.

NEXT STEPS
Following the encouraging initial result, the program has been expanded to 7,000 metres. This will
allow Falcon to complete the original planned drilling of the Olsen Well prospect as well as additional
drilling around OWRC0001 to improve the understanding of the orientation and scale of the high-
grade zone that has already been confirmed.
Falcon will also submit 1-metre splits from any significant intercepts returned, as initial assays are
taken as 4-metre composite samples.

About the Errabiddy Gold Project
The Errabiddy Gold Project is centred on the Errabiddy Shear Zone, a major crustal-scale structure
marking the boundary between the Yilgarn Craton and the Glenburgh Terrane of the Capricorn Orogen.
Craton margins are recognised as highly prospective locations for major gold deposits, including
Tropicana on the eastern margin of the Yilgarn Craton and the 2.6Moz Karlawinda Gold Project1
on
the southern margin of the Pilbara Craton (see Figure 5).
The Errabiddy Shear Zone contains known gold mineralisation, including the Big Sky Prospect
discovered by Lodestar Minerals in 20152
less than 3km from Falcon's tenure. The nearby Glenburgh
Gold Project (owned by Benz Mining ASX:BNZ) is located approximately 35km northwest of Olsen Well,
and is also interpreted to be associated with a craton-margin setting.
Falcon identified the Errabiddy Shear Zone as a highly prospective target for large-scale gold
mineralisation, with historical stream sediment anomalism highlighting the Olsen Well area. Since
securing an option over the project, Falcon has completed multiple phases of surface geochemical
sampling that have expanded the Olsen Well anomaly to 5.8km of strike at greater than 10ppb gold in
soils and confirmed anomalous gold in bedrock. These results have increased confidence in the
potential for a significant mineralised system and led to the current drilling program.
Falcon can earn a 70% interest in Exploration Licence E09/2457 (excluding graphite rights) from ASX-
listed West Coast Silver Limited (ASX: WCE). The adjoining E09/2984 is 100%-owned.
This announcement has been approved for release by the Board of Falcon Metals.

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.
• Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.
• 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.
• The RC samples were collected in 1m calico bags that were
split on a riffle splitter.
• 4m composite samples were collected using a scoop from
the sample pile that was placed on a cleared area.
• The 4m composite samples from the entire hole were
submitted for 50g fire assay for gold and 4 acid digest for
pathfinder elements.
• 1m samples will be submitted from geological zones of
interest for 50g fire assay.
• All samples were pulverised to nominal 80% passing 75
microns to produce a 50g charge for fire assay.
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).
• The RC drilling was completed by Bostech Drilling Australia.
Tungsten-carbide button hammer face sampling bits were
used.
• A face sampling bit with a diameter of 104mm is used at the
commencement of the hole. If the penetration rate slows, a
face sampling bit with a diameter of 100mm is used to
complete the hole.
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.
• The sample recovery was estimated by the size and weight
of the material in each sample pile and recorded as a
percentage, with contamination recorded if evidence of this
was identified.
• Sample condition was recorded during logging
(wet/moderate/dry)
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.
• Whether logging is qualitative or quantitative
in nature. Core (or costean, channel, etc)
photography.
• The total length and percentage of the
relevant intersections logged.
• The RC chips were geologically logged in 1m intervals. This
included weathering, regolith, lithology, texture, alteration
and mineralisation.
• Logging is considered quantitative in nature.
• The RC chips were logged and sampled at the rig with the
entire hole being logged.
