HIGH-GRADE TIN & COPPER DISCOVERY AT MONTEZUMA
Returning Grades of 7.3% Tin, 6.8% Copper, 863 g/t Silver, 1.8g/t Gold,
2.1% Antimony & 4.0% Lead
Highlights
• New high-grade discovery adds a fourth commodity suite to Montezuma: Assays from the
newly identified Sn-Cu-Ag-Sb-Au-Pb lode in MZS43 returned a high-grade 0.5m @ 7.3% Sn,
6.8% Cu, 863g/t Ag, 1.8g/t Au, 2.1% Sb & 4.0% Pb, thereby expanding Montezuma's known
Ag-Sb endowment into high grade tin and copper.
• Further assay news flow expected: Results are pending for the other three mineralised
intercepts in MZS43, including 2.2m and 15.4m of Maestries base metal replacement
mineralisation.
• System proven larger than currently modelled: MZS43, the first hole drilled from the
hanging wall (eastern) side of the Montezuma Resource, intersected four separate mineralised
lodes in a single hole:
o Sn-Cu-Ag-Sb-Au-Pb Moores Lode (new, hanging wall)
o Ag-Sb Montezuma Lode
o Two Pb-Zn-Ag replacement lodes (Maestries footwall dolomitic conglomerate)24
• New target style validated: Follow-up to MZS42 (6.40m @ 6.2% Zn, 1.5% Pb, 0.1% Sb, 43g/t
Ag & 0.1g/t Au) confirms a new replacement-style silver-zinc target in the Maestries
conglomerate24
, a second mineralisation style now open for follow-up.
• Drilling underway to convert targets into resource: Current holes are testing the Maestries
base metal system further west, extending Montezuma's Ag-Sb mineralisation, and following
up the new hanging-wall Sn-Cu-Ag Moores Lode.
• Regional pipeline building: Exploration continues at the Fahlore, Silver Cliffs and Persic high-
grade silver-antimony prospects — viewed as potential satellite deposits to Montezuma.
• Growth thesis reinforced, next catalyst already underway: With multiple new drill targets
defined at Montezuma and across Lode's wider Tasmanian West Coast portfolio, the Company
is increasingly confident of growing its maiden 8.2Moz AgEq resource (announced 14 April
22). Follow-up hole MZS44 (designed to test directly below MZS43) is already in progress.

Lode’s Managing Director Keith Mayes said: “The first assays from this highly mineralised lode have
provided us with Montezuma’s highest tin and copper grades to date. Together with extensions to the
Montezuma Lode and the two replacement lodes, this drilling further demonstrates the substantial
mineral endowment of the Montezuma project. We have now identified multiple new zones of
mineralisation since the initial resource estimate and these have the potential to materially enhance size
and overall project economics. We look forward to reporting the remaining assay results for drill hole
MZS43 and the follow-up hole MZS44, designed to test below MZS43 that is in progress”.

west of the Montezuma Lode. The replacement style mineralisation is hosted in
dolomitic sediments of the Maestries Conglomerate approximately 50-80m west of the Montezuma
Fault (see Figures 2 and 3). Mineralisation is associated with carboniferous granitic intrusions
responsible for tin-tungsten and silver-lead-zinc-antimony mineralisation in the highly mineralised West
Coast region of Western Tasmania.
Lode’s tenements EL7/2019 and 2M/2023 host a mineralised system associated with carboniferous
granite intrusions. Sulphide mineralisation includes multiple commodities including Ag-Pb-Zn fissure
lodes with critical mineral associations of Sb, Bi, Sn and W. This polymetallic character is a key attribute
of the project which is evolving with ongoing exploration.
The Montezuma deposit is hosted within fissure veins along the north-south trending Montezuma fault
and associated splay structures. The Fault dips steeply east, with drill defined mineralisation
extending over 250m strike length and 200m down dip, remaining open in all directions. An
inaugural 8.2 Moz AgEq resource was announced on 14 April 22
.
A new hanging wall lode (Moores Lode), very similar to the Montezuma Lode has been identified in
Drillhole MZS43 consisting of a fissure vein of pyrite-chalcopyrite-jamesonite-galena-arsenopyrite (see
Figures 1, 2 and 3). Early results for the hanging wall lode include:

Drillhole MZS43 was designed to test the southern extension of the Montezuma Silver-Antimony Lode
and the replacement Maestries Silver-Zinc-Lead mineralisation, identifying significant sulphide
mineralisation in both target areas.
MZS43 was the first hole drilled by Lode Resources from the hanging wall side of the Montezuma Lode,
providing improved drilling angles and coverage of both mineralised targets on the southern end of the
prospect (Figure 2). Additional drill holes are planned from this collar position testing the southern
extension of the Montezuma Lode and the Maestries replacement lodes. Drill hole MZS44 is currently
in progress.
LDR are pleased to announce that significant sulphide mineralisation was intercepted in the Montezuma
Lode and the Maestries replacement lode in MZS4326
. In addition, a new Sn-Cu-Ag lode (Moores Lode)
was identified 60m in the hanging wall of the Montezuma lode (see Figure 3).
Drill core for the lower three mineralised zones is currently being assayed with samples delivered to
ALS laboratories in Burnie on Wednesday 19th
August 2026. Assay results are anticipated
approximately 1 month from drop off.

A new hanging wall fissure lode (Moores Lode) hosting very similar mineralisation to the
Montezuma Lode was intersected at 133.5 - 134.5m for 1.0m down hole. The intercept consisted
of massive banded jamesonite (Pb4FeSb6S14) - pyrite (FeS2) – chalcopyrite (CuFeS2) - arsenopyrite
(FeAsS) - tetrahedrite ((Cu,Fe,Ag)12(Sb,As)4S13) vein (Figure 4). Assay results received average 1m
downhole width of 437g/tAg, 3.4% Cu, 2.4% Pb, 1.2% Sb, 1.2g/t Au and 3.7% Sn (Table 1).

Intercepts for drill hole MZS43 where assays remain outstanding are described below:
Two intercepts of the Montezuma Lode were intersected. The first at 220.4 to 221.5m, consisting of
0.4m of massive chalcopyrite (CuFeS2) and 0.7m of massive pyrite-arsenopyrite-tetrahedrite
mineralisation (Figure 5).

Several intercepts of massive base metal sulphide mineralisation were intercepted within the Maestries
conglomerate-dolomite. The first consisted of 2.2m downhole of coarse-grained sphalerite (Zn,FeS) –
galena (PbS) – pyrite – arsenopyrite - tetrahedrite vein mineralisation between 370.5 and 372.7m depth
(Figure 7).

The second replacement lode within the Maestries dolomites included a broad 15.4m intersection of
replacement sphalerite-galena-pyrite between 411.8m and 427.2m (Figures 8 – 12). Included in the
zone were two massive sphalerite-galena lodes at 413.8 – 414.3m (0.7m downhole) and 420.6 –
426.3m (5.7m downhole). The surrounding mineralisation consisted of lower grade disseminated
sphalerite, pyrite-arsenopyrite.

Montezuma Silver & Antimony Metal Equivalent Grades
LDR is reporting both silver & antimony equivalent grade figures due to interchanging dominance of these two
metals from intercept to intercept. Metal equivalent grade figures are a method of demonstrating overall metal
endowment for all significant metal grades in a single grade figure for each intercept and thus allowing a
simpler comparison between intercepts. Montezuma’s reported silver & antimony equivalent figures are based
on conversion factors as follows:
AgEq(g/t) = Ag(g/t) + 357*Sb(%) + 20*Pb(%) + 91*Cu(%)
Metal equivalent conversion factors were calculated using 30 December 2024 metal prices of US$34,747/t
antimony, US$29.1/oz silver, US$1,912/t lead and US$8,705/t copper. The antimony price was calculated as
an average of several antimony products in several markets including:
antimony concentrate delivered China
antimony ingot FOB China
antimony trioxide FOB China
antimony trioxide in warehouse Baltimore
antimony ingot in warehouse Baltimore
antimony trioxide in warehouse Baltimore
antimony trioxide in warehouse Rotterdam
Metal equivalent conversion factors were calculated using a preliminary flotation test carried out by ALS
Metallurgy (Burnie) in March 2026, where recoveries achieved were 88.4% antimony, 93.0% silver, 88.4%
lead and 91.5% copper. It is Lode’s opinion that all the elements included in the metal equivalents
calculation have a reasonable potential to be recovered and sold.
Figure 13. Antimony prices for various markets

Tin and Gold Assays
Tin and Gold assay figures are not included in equivalent figures as gold was not assayed in an early flotation
test. ALS Metallurgy has been commissioned to complete further comprehensive flotation tests on Montezuma
Silver & Antimony mineralisation including the recovery of tin and gold. This includes Quantitative X-ray
Diffraction (QXRD) analysis to determine overall mineralogy.
The Montezuma Silver & Antimony Project
The Montezuma Silver & Antimony Project includes a high-grade silver & antimony resource of 8.2Moz
AgEq1,22
at 533g/tAgEq1
using 200g/tAgEq cutoff with initial development, advanced metallurgical test work
and considerable beneficiation infrastructure. Access is via the Zeehan township located 13km to the west.
The Montezuma Silver & Antimony Project (2M-2023, EL7-2019) is located between well-known mining
centres such as:
US$34747/t antimony price assumption

Antimony - One of the World’s most critical metals
Antimony is classified as a critical metal by both the Australian Federal Government and the Tasmanian State
Government, as well as almost every advanced western nation. Antimony markets tightened further when
China announced a ban on antimony exports specifically to the United States on 3 December 2024*. This
curb strengthened the enforcement of existing limits on critical minerals exported announcement by China in
the prior year and the more specific ban on certain antimony product exports early in 2024, all due to national
security concerns.
In November 2025, China agreed to suspend its export controls on rare earths and other critical minerals,
including antimony, following a new trade and economic deal with the United States. This doesn’t change
China’s strong dominance of the global antimony market, nor the mercurial nature of both countries’ trading
policies. Europe remains outside the agreement.
The Tasmanian Government recently outlined a Critical Minerals Strategy which includes the objective of
growing exploration for critical minerals and supporting critical minerals projects. Montezuma, 100% owned
by Lode, is Tasmania’s only antimony project**.

standard’ work has been done this would
be relatively simple (e.g. ‘reverse
circulation drilling was used to obtain 1m
samples from which 3kg was pulverized to
produce 30g 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 sampling types

techniques were used at the Montezuma Silver &
Antimony Project to obtain NQ2 (50.7mm diameter)
diamond core.
• An underground Atlas Copco Diamec drill rig was
used to drill MZS43 in steep topography. Drilling
orientation was designed to intercept the
mineralisation at a high angle to ensure
representivity.

distribution is sufficient to establish the
degree of geological and grade continuity
appropriate for the Mineral Resource and
Ore Reserve estimation procedure(s) and
classifications applied.
• Whether sample compositing has been
applied.
• Drill holes were designed to provide a 25 x 25 to 50
x 50m drilling pattern.
• Drilling is designed to extend the Montezuma
resource and test the Maestries Replacement Lode.
• The data spacing, distribution and geological
understanding is considered to be sufficient for the
estimation of mineral resource estimation within
close spaced drilling pattern.
• No sample compositing has been applied.
Orientation of
data in relation to
geological
structure
• Whether the orientation of sampling
achieves unbiased sampling of possible
structures and the extent to which this is
known, considering the deposit type.
• If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to
have introduced a sampling bias, this
should be assessed and reported if
material.
• Drill holes were designed to intersect the
mineralised lodes approximately perpendicular to
the strike and dip and are considered close to true
width.
• An underground drill rig was used to allow multiple
high angle holes from the same drill pad.
• Drill hole orientation is not considered to have
introduced any bias.
Sample security • The measures taken to ensure sample
security.
• Samples were bagged and sealed on site and
transported to ALS Burnie by LDR staff.
Audits or reviews • The results of any audits or reviews of
sampling techniques and data.
• No audits or reviews have been carried out at this
point.
