Eloro Resources Ltd. (TSX: ELO; OTCQX: ELRRF; FSE:
P2QM) (“Eloro”, or the “Company”) is pleased to announce
the final assay results for the last six (6) diamond drill holes in
its
eleven (11) hole
5,267.7m
definition drill program on the Iska Iska silver-tin polymetallic
project in the Potosi Department of southwestern Bolivia.
Tom Larsen, CEO of Eloro commented: “I am very
pleased with the continuation of significantly higher-grade silver
equivalent results from the latest definition drilling program,
compared to the initial mineral resource estimate (“MRE”) starter
pit area model as previously reported (see Eloro press release
dated Oct 17, 2023). These new results highlight the potential to
upgrade and expand the higher-grade resource in the Santa Barbara
starter pit area."
Larsen continued: "Tin is proving to be an
important metal contributor to these upgraded silver equivalent
results. This can enhance NSR values and increase tonnage in future
MRE studies. As an example, Hole DSB-63 located in the Northeast
section of the Santa Barbara starter pit area, recognized more as a
Polymetallic (Ag-Zn-Pb) Domain, returned 0.51% tin over a
23.02-meter drill intercept with a total silver equivalent
value of 205.57 g/t.
There is more and more evidence of high
temperature sulphidation centres being identified as feeders within
the open pit area resulting in upgraded tin and silver values.
Higher density definition drilling in the initial Santa Barbara
open pit envelope is consistently proving up higher grades as drill
density is improved."
Dr. Osvaldo Arce, P.Geo. General Manager of
Eloro’s Bolivian subsidiary Minera Tupiza S.R.L. and an expert on
Bolivian mineral deposits said: “The definition drilling is
confirming a strong high-grade Ag-Sn association, which is common
in the southern Bolivian Tin Belt, including in large systems at
Cerro Rico de Potosi, Animas-Siete Suyos-Chocaya and Tatasi
deposits that occur along NW-SE striking structural corridors, the
same geological environment that is present at Iska Iska.”
Dr. Arce continued: “Recent drilling results
have outlined upgraded tin and silver values from near surface down
to at least 500m in vertical extent, principally in the sulphide
zone. Geophysical information and deep drilling indicate that
tin-silver mineralization may extend to depths of 1km or more. Tin
mineralization in these zones has been remobilized and redeposited
throughout the deposit by brecciation in favorable rock types,
especially medium grained porphyritic dacite and intrusion breccia
which are the most widespread lithologies at Iska Iska. Moreover,
tin-polymetallic mineralization can be locally extensive/continuous
as occurs in hole DSB-67, where 477m of the 500m drilled averages
about 0.1% Sn, with almost no waste material. This high-grade
continuous polymetallic mineralization forms commonly subhorizontal
vein-parallel banding along north-northwest trending shear zones,
indicating multiple episodes of fracture opening and mineral
precipitation.”
DEFINITION DRILL PROGRAM
Table 1 below lists significant results for the
six drill holes reported. Figure 1 shows locations of all the
definition drill holes completed with the holes reported in this
release highlighted. Silver equivalent (g Ag/t) has been calculated
using 3-year average metal prices and preliminary metallurgical
recoveries (see note below Table 1 for more information). Table 2
lists the coordinates of the definition drill holes reported in
this release.
The definition diamond drill program focussed on
upgrading and expanding the higher-grade Polymetallic (Ag-Zn-Pb)
Domain Type inferred mineral resource, which as previously reported
(see Eloro press release dated October 17, 2023) contains an
inferred mineral resource of 132 million tonnes at 24.3 g Ag/t,
1.11% Zn and 0.50% Pb (72.06 g Ag eq/t) at an NSR cutoff of
$US25/t. The net NSR value of this higher-grade resource is
US$34.40/t which is 3.75 times the estimated operating cost of
US$9.20/t. Several of these holes also tested the adjacent Tin
(Sn-Ag-Pb) Domain where high values of silver (Ag) have previously
also been obtained in addition to tin (Sn).
Drill hole locations were planned to fill-in
major gaps in the block model as well as upgrade and expand the
higher-grade zone both along and across strike in the general area
of the potential starter pit. As noted by Micon International
Limited (“Micon”), authors of the National Instrument 43-101 (“NI
43-101”) Technical Report detailing the initial Iska Iska MRE (see
Eloro press release dated October 17, 2023), the highest-grade
areas are also the best drilled. As drill density in the deposit is
improved, it is expected that grade will increase due to better
sample density. Results previously reported (see Eloro press
released dated December 18, 2023) and results reported herein
confirm that this is likely the case.
Figures 2 and 3 are west-east sections showing
the distribution of tin and silver, respectively, incorporating
definition drill results along with distribution of mineral
resource blocks with an NSR value greater than US$25 per tonne from
the Micon mineral resource model. These sections highlight how the
definition drill program has expanded both the higher-grade Sn and
Ag zones especially to the west where there has been very little
previous drilling.
These new data highlight the potential for
expanding the mineral resource particularly outlining a significant
higher-grade Sn resource to include for consideration in the PEA.
As noted in the Eloro press release of November 1, 2023, the PEA
was planned to focus solely on the higher-grade Polymetallic
(Ag-Zn-Pb) with Sn being a major exploration target. The results of
the definition drill program highlight the potential to
significantly expand the higher-grade Sn resource to the west of
the current potential pit and to incorporate this new potential
resource area into consideration for the PEA.
The following is a summary of significant
diamond drill results from the six holes:
Hole DSB-66 intersected several
long well mineralized intervals as follows:
- 57.62g
Ag/t, 1.26% Zn, 0.94% Pb and 0.12% Sn (139.94g Ag eq/t) over
136.11m from 137.75m to 273.86m including:
- 136.81g
Ag/t, 2.00% Zn, 1.38% Pb and 0.17% Sn (255.19g Ag eq/t) over
34.77m from 187.64m to 222.41m
- 24.67g
Ag/t, 1.08% Zn, 0.83% Pb and 0.08% Sn (94.46g Ag eq/t) over
86.39m from 288.92m to 375.31m including:
- 69.37g
Ag/t, 0.41g Au/t, 1.88% Zn, 3.68% Pb and 0.32% Sn
(272.27g Ag eq/t) over 6.08m from 307.15m to 313.23m,
- 23.59g
Ag/t, 2.14% Zn, 1.57% Pb and 0.15% Sn (159.64g Ag
eq/t) over 6.15m from 328.23m to 334.38m, and
- 99.40g
Ag/t, 1.60% Zn, 1.06% Pb and 0.10% Sn (187.52g Ag eq/t) over
12.24m from 360.02m to 372.26m
- 7.46g
Ag/t, 2.51% Zn, 1.02% Pb and 0.06% Sn (129.90g Ag
eq/t) over 74.85m from 415.85m to 490.70m
- 10.80g
Ag/t, 0.12 g Au/t, 4.96% Zn, 1.49% Pb and 0.06% Sn (229.62g Ag
eq/t) over 16.86m from 430.99m to 447.85m
- 13.86g
Ag/t, 4.20% Zn, 2.35% Pb and 0.34% Sn(277.75g Ag eq/t) over
7.76m from 457.31m to 465.07m
Hole DSB-65 collared 100m west
of hole DSB-66 intersected the highest-grade silver sample
intersected thus far at Iska Iska in an 80+m wide well mineralized
zone as follows:
- 118.86g
Ag/t, 0.35% Zn, 0.35% Pb and 0.15% Sn (152.29g Ag eq/t) over
81.28m from 353.49m to 434.77m including:
- 5,080g
Ag/t, 0.12 g Au/t, 0.26% Zn, 1.34% Pb, 1.53% Cu and 1.27% Sn
(4,746.46g Ag eq/t) over 1.46m from 362.53m to
363.99m
- Cutting of this
very high Ag sample to 1,000g Ag/t based on a statistical
probability plot yields a still high average for the 81.28m
interval of 45.58 g Ag/t with an overall grade of
87.80 g Ag eq/t
- This very
high-grade sample highlights the potential for Iska Iska to host
extraordinary grades within the overall extensive mineralized
system.
Hole DSB-67 collared 200m
south-southwest of DSB-66 intersected a wide zone of mineralization
grading 8.17 g Ag/t, 1.40% Zn, 0.48% Pb and 0.06% Sn
(79.08g Ag eq/t) over 236.13m from 240.04m to 476.17m
including higher grade zones of:
- 2.17g
Ag/t, 0.16 g Au/t, 2.65% Zn, 0.52% Pb and 0.06% Sn (118.18g Ag
eq/t) over 9.03m from 249.09m to 258.12m and
- 28.10g
Ag/t, 4.25% Zn, 1.67% Pb and 0.17% Sn (245.05g Ag eq/t) over
19.45m from 434.06m to 453.51m
Hole DSB-60 intersected a
158.58m long zone of lower grade mineralization
with higher-grade zones as follows:
- 16g
Ag/t, 0.66% Zn, 0.41% Pb and 0.09% Sn (63.23g Ag eq/t) over
158.58m from 15.33m to 173.91m including:
- 23.31g
Ag/t, 1.18% Zn, 0.56% Pb and 0.16%Sn (105.56 g Ag eq/t) over
6.16m from 34.99m to 41.15m and
- 115.54g
Ag/t, 1.45% Zn and 1.67% Pb (201.17g Ag eq/t) over 4.54m
from 139.32m to 143.86m
Hole DSB-63, the eastern most
hole in the definition drill program, intersected a significant Sn
intersection of 23.37 g Ag/t, 1.77% Zn. 1.22% Pb and 0.51%
Sn (205.57g Ag eq/t) over 23.02m from 446.10m to 469.12m.
This area is in the Polymetallic (Ag-Zn-Pb) Domain where Sn values
have typically been low. This suggests potential to extend the
higher-grade Sn zone further east.
Hole DSB-64, the southwestern
most hole in the definition drill program, intersected
113.33g Ag/t and 0.12 g Au/t (110.97 g Ag eq/t) over
22.91m from 35.22m to 58.13m and 172.37 g Ag/t and
0.17% Pb% (161.78g Ag eq/t) over 13.46m from 135.83m to
149.29m. This hole was terminated at 240m due to faulting short of
its planned depth of 500m.

Note: True width is approximately 80% of core length. Silver
equivalent (Ag eq) grades are calculated using 3-year average metal
prices of Ag = US$22.52/oz, Zn = US$1.33/lb , Pb = 0.95/lb
and Sn = US$12.20/lb, and preliminary metallurgical
recoveries of Ag = 88%, Zn = 87%, Pb= 80% and Sn =
50%. Au and Cu assay results are provided as they are of
potential economic interest however these values are not included
in the Ag eq calculation as metallurgical recovery has not yet been
established for these elements. In selecting intervals, a cutoff
grade of 30 g Ag eq/t has been used. Lower grade material may be
included in intersections where geological continuity is
warranted.

Qualified Person (“QP”)
The inaugural MRE for Iska Iska outlined in the
NI 43-101 Technical Report (see Eloro press release dated October
17, 2023) has been prepared by Micon International Limited.
Independent QPs for the Technical Report are Charley Murahwi,
P.Geo., FAusIMM, Richard Gowans, P.Eng., Ing. Alan J. San Martin,
MAusIMM (CP) and Abdul Aziz, Drame, P.Eng., all of whom are
independent QP’s as defined by NI 43-101. Mr. Murahwi completed
site visits in January 2020 and November 2022.
Dr. Bill Pearson, P.Geo., Vice President
Exploration, Eloro and a QP as defined by NI 43-101 has reviewed
and approved the technical content of this news release. Dr.
Pearson who has more than 48 years of worldwide mining exploration,
development and production experience, including extensive work in
South America, manages the overall technical program, working
closely with Dr. Osvaldo Arce, P.Geo. General Manager of Eloro’s
Bolivian subsidiary, Minera Tupiza S.R.L., and a Qualified Person
in the context of NI 43-101, who has supervised all field work
carried out at Iska Iska.
Eloro utilized both ALS and AHK for drill core
analyses, both of whom are major international accredited
laboratories. Drill samples sent to ALS were prepared in both
ALS Bolivia Ltda’s preparation facility in Oruro, Bolivia and
the preparation facility operated by AHK in Tupiza with pulps sent
to the main ALS Global laboratory in Lima for analysis. Eloro
employs an industry standard QA/QC program with standards, blanks
and duplicates inserted into each batch of samples analyzed with
selected check samples sent to a separate accredited
laboratory.
Drill core samples sent to AHK Laboratories were
prepared in a preparation facility installed and managed by AHK in
Tupiza with pulps sent to the AHK laboratory in Lima, Peru. Check
samples between ALS and AHK are regularly done as a QA/QC check.
AHK is followed the same analytical protocols used as with ALS and
with the same QA/QC protocols.
About Iska Iska
Iska Iska silver-tin polymetallic project is a
road accessible, royalty-free property, wholly controlled by the
Title Holder, Empresa Minera Villegas S.R.L. and is located 48 km
north of Tupiza city, in the Sud Chichas Province of the Department
of Potosi in southern Bolivia. Eloro has an option to earn a 100%
interest in Iska Iska.
Iska Iska is a major silver-tin polymetallic
porphyry-epithermal complex associated with a Miocene possibly
collapsed/resurgent caldera, emplaced on Ordovician age rocks with
major breccia pipes, dacitic domes and hydrothermal breccias. The
caldera is 1.6km by 1.8km in dimension with a vertical extent of at
least 1km. Mineralization age is similar to Cerro Rico de Potosí
and other major deposits such as San Vicente, Chorolque, Tasna and
Tatasi located in the same geological trend.
Eloro began underground diamond drilling from
the Huayra Kasa underground workings at Iska Iska on September 13,
2020. On November 18, 2020, Eloro announced the discovery of a
significant breccia pipe with extensive silver polymetallic
mineralization just east of the Huayra Kasa underground workings
and a high-grade gold-bismuth zone in the underground workings. On
November 24, 2020, Eloro announced the discovery of the SBBP
approximately 150m southwest of the Huayra Kasa underground
workings.
Subsequently, on January 26, 2021, Eloro
announced significant results from the first drilling at the SBBP
including the discovery hole from 0.0m to 257.5m. Subsequent
drilling has confirmed significant values of Ag-Sn polymetallic
mineralization in the SBBP and the adjacent CBP. A substantive
mineralized envelope which is open along strike and down-dip
extends around both major breccia pipes. Continuous channel
sampling of the Santa Barbara Adit located to the east of SBBP
returned 164.96 g Ag/t, 0.46%Sn, 3.46% Pb and 0.14% Cu over 166m
including 446 g Ag/t, 9.03% Pb and 1.16% Sn over 56.19m. The west
end of the adit intersects the end of the SBBP.
Since the initial discovery hole DHK-15 which
returned 29.53g Ag/t, 0.078g Au/t, 1.45%Zn, 0.59%Pb, 0.080%Cu and
0.056%Sn over 257.5m, Eloro has released a number of significant
drill results in the SBBP and the surrounding mineralized envelope
which along with geophysical data has defined an extensive target
zone. On October 17, 2023, Eloro filed the NI 43-101 Technical
Report outlining the initial inferred MRE for Iska Iska, prepared
by Micon International Limited. The MRE was reported in two
domains, the Polymetallic (Ag-Zn-Pb) Domain which is primarily in
the east and south of the Santa Barbara deposit and the Tin
(Sn-Ag-Pb) Domain which is primarily in the west and north. The
Polymetallic Domain is estimated to contain 560Mt at 13.8 g Ag/t,
0.73% Zn & 0.28% Pb at an NSR cutoff of US$9.20 for potential
open pit and an NSR cutoff of US$34.40 for potential underground.
The majority of the mineral resource is contained in the
constraining pit which has a stripping ratio of 1:1.
The Polymetallic Domain contains a higher-grade
mineral resource at a NSR cutoff of $US25/t of 132 million tonnes
at 1.11% Zn, 0.50% Pb and 24.3 g Ag/t which has a net NSR value of
US$34.40/t which is 3.75 the estimated operating cost of US$9.20/t.
The Tin Domain which is adjacent the Polymetallic Domain and does
not overlap, is estimated to contain a mineral resource of 110Mt at
0.12% Sn, 14.2 g Ag/t and 0.14% Pb but is very under drilled.
The Company has completed a 5,267.7m definition
drill program to upgrade and expand the higher-grade mineral
resource in the Polymetallic Domain and has commenced a preliminary
economic evaluation (PEA) led by Lycopodium.
