Aldebaran Corrects August 18th, 2022 News Release

VANCOUVER, CANADA ( August 19 , 2022 ) – In a release issued yesterday, August 18, 2022, for Aldebaran

Resources Inc. (“Aldebaran” or the “Company”) (TSX-V: ALDE, OTCQX: ADBRF), please note that the length

of the upper zone in drillhole ALD- 22-221 was 89.0 m rather than 64 .0 m and started at 240.0 m depth rather than

22.0 m depth. The grades were reported correctly. Also, the lower zone of ALD-22-221 started at 428.0 m depth rather

than 228.0 m depth. The length and grades were reported correctly. The corrected release follows:

Aldebaran is pleased to report results from drill holes ALD-22-220 and ALD-22-221. The goal of both holes was to

test for extensions of mineralization of the Altar Central and Altar East deposits. Hole ALD-22-220 tested for a south-

western extension of Altar Central, while A LD-22-221 tested for mineralization in between Altar Central and Altar

East in an area previously not drilled. In addition, ALD -22-221 also tested the northern edge of the very large 3D

IP/MT geophysical anomaly recently reported by the Company (see news release dated June 13, 2022) however, the

hole was started before the final geophysical data was received so it did not test the centre of the anomaly. Both holes

successfully intercepted mineralization ; ALD-22-221 intercepted a long run of mineralization indicating that the

geophysical anomaly correlates well with mineralization, which opens a very large new area for additional exploration.

Highlights

ALD-22-221

● 89.00 m of 0.38% CuEq from 240 m depth (secondary copper sulphide zone)

● 1,059.50 m of 0.40% CuEq from 428 m depth (primary copper sulphide zone)

o Including 50.00m of 0.72% CuEq from 660 m depth

o And 95.05m of 0.64% CuEq from 832 m depth

● Hole ALD-22-221 tested the northern edge of a very large 3D IP/MT geophysical anomaly; the results of

this hole indicate that the geophysics correlate well with known mineralization (see Figure 3)

● The hole ended in mineralization

ALD-22-220

● 284.00 m of 0.41% CuEq from 462 m depth

o Including 100.00 m of 0.55% CuEq from 462 m depth

● 135.00 m of 0.23% CuEq from 809 m depth

John Black, Chief Executive Officer of Aldebaran, commented as follows: “Hole 221 is very encouraging as it

returned over a kilometer of mineralization in an area previously thought to be barren. Also, this hole provides a

strong proof of concept that the 3D IP/MT geophysical targets correlate well with mineralization. Although this hole

was started prior to receiving the geophysical data and didn’t centre punch the anomaly, it still provides confidence

that where we drill the geophysical anomaly, we are likely to hit mineralization. Based on the size of the anomaly, this

deposit has the potential to become much larger. Hole 220 also successfully expanded the footprint of Altar Central

to the southwest and will require additional drilling to test the full extent of the mineralization. We look forward to

getting back on site in the second half of 2022 to start drilling this sizeable geophysical anomaly from more strategic

locations.”

Dr. Kevin B. Heather, Chief Geological Officer of Aldebaran, commented as follows: “Drill holes 220 and 221

confirm our long-held belief that the Altar system is much bigger tha n previously thought . The new 3D IP/MT

geophysical anomaly correlates extremely well with the known mineralization that makes up the 2021 in-pit resource

at both Altar Central and Altar East and also with mineralized drill holes that extend below and laterally away from

that conceptual pit resource. Of particular interest, mineralization in 221 is hosted entirely within both favourable

and historically less favourable wall rock units, suggesting the mineralizing source is nearby. Altar has the potential

to become extremely large and we look forward to drilling additional holes into the untested portions of the

geophysical anomaly.”

The grades are uncut. CuEq values were calculated using copper, gold, silver and molybdenum. Metal prices utilized for the calculations are Cu

= US$3.00/lb, Au = US$1,400/oz, Ag = US$18/oz, and Mo = US$10/lb. No adjustments were made for recovery as the pr oject is an early -stage

exploration project and metallurgical data to allow for estimation of recoveries is not yet available. The formulas utilized to calculate equivalent

values is CuEq % = Cu % + Au g/t * 0.6805 + Ag g/t * 0.00875 + Mo ppm / 3000 .

Discussion of Results:

ALD-22-220

Drillhole ALD-22-220 was drilled at -70 degree dip and an azimuth of 50 degrees to a final depth of 1,186.50 m. The

purpose of the hole was to test for the extension of mineralization with a strong, multi-element geochemical anomaly

with a NW-SE trend related to the Altar Central porphyry center. The hole intersected a mixed sequence of massive

to fragmental andesitic volcanic rocks and, from 0 to 155 m depth and from 155 m to 480 m depth, a thick sequence

of massive to fragmental rhyolitic volcanic rocks with possible crosscutting hypabyssal rhyolitic porphyry intrusions.

From 480 m to 770 m, the hole once again encountered a mixed sequence of massive to fragmental andesitic volcanic

rocks before entering a heterolithic magmatic-hydrothermal breccia from 770 m to 814 m. From 814 m until the end

of the hole (1,186.50 m), the hole continued in the mixed sequence of massive to fragmental andesitic volcanic rocks.

This drillhole encountered strong epidote -chlorite-magnetite-hematite-pyrite alteration (i.e., propylitic assemblage)

over the upper 155 m before entering a long run of strong sericite-pyrite-tourmaline-quartz-chalcopyrite alteration,

associated with the occurrence of moderate copper mineralization. Starting at 815 m depth until the end of the hole,

ALD-22-220 intersected moderate biotite-magnetite-potassium-feldspar alteration associated with weak quartz

veining containing chalcopyrite and molybdenite. The alteration and mineralization encountered in this drill hole

suggest that we have drilled into the outer portion of the system in the upper portion of the hole and progressively

drilled back in towards the central portion of the Altar Central system.

ALD-22-221

Drillhole ALD-22-221 was drilled at a -80 degrees dip and an azimuth of 265 degrees to a final depth of 1487.50 m.

The hole was drilled into a previously untested area located in between the known mineralization at Altar Central and

Altar East. The only hole within a 200 m radius is ALD-07-024, which was drilled only to 445.8 m depth. Hole ALD-

22-221 was collared and started before the receipt of the final 3D IP/MT geophysical survey results however, the hole

does test the northern margin of a very large (4 km x 3.5 km x 2 km), coincident DCIP -Resistivity and 3DMT -

Resistivity, conductive anomaly. Hole ALD-22-221 cut through a quartz diorite intrusion with strong stockwork quartz

veining from surface to 302 m depth, before passing into a thick sequenc e of massive porphyritic and fragmental

rhyolites to a depth of 674 m. From 674 m to 973 m, the hole encountered a sequence of massive to fragmental

andesitic volcanic rocks and then, from 973 m until 1,181 m, a massive porphyritic rhyolite unit. From 1,181 m until

the end of the hole at a depth of 1,487.50 m, the hole encountered the andesitic volcanic rocks again. The fragmental

rhyolites are interpreted to be part of the regional ~20 Ma aged volcanic stratigraphy, whereas some of the porphyritic

rhyolites may be cross-cutting intrusive dykes related to a younger mineralizing porphyry event, but further geological

work, along with Re-Os molybdenite and U-Pb zircon age-dating, is being done to address this as part of an ongoing

doctoral research study being completed on the project.

Drillhole ALD-22-221 encountered a strongly oxidized and leached zone to 240 m depth, followed by an 89 m thick

horizon of moderately developed secondary copper sulphide enrichment consisting of chalcocite on pyrite. This zone

of enrichment is in an area within the 2021 conceptual pit shell, that is currently classified as waste material ; hence

this and any follow- up drilling will add to the currently known secondary copper resource. Hole ALD -22-221 also

shows a strong lithological control on both favourable alteration and the better mineralization.

The rhyolite intervals display strong (a) quartz – sericite – pyrite - chalcopyrite, (b) quartz – tourmaline - pyrite, and

(c) quartz – pyrite - enargite assemblages with low to modera te copper values and elevated arsenic contents.

Historically the rhyolitic rocks at the Altar project have been poor and somewhat unreceptive host rocks for

mineralization however, moderately mineralized rhyolites in hole ALD- 22-221 suggest that the system is getting

stronger such that even these less favourable host rocks are being mineralized , whereas the andesitic rocks display

moderate to strong biotite and potassium -feldspar (i.e., potassic alteration) that increases towards the bottom of the

hole. This potassic alteration is overprinted by an assemblage of moderate intensity green sericite-pyrite-chalcopyrite

± bornite which are associated to moderate and continuous copper grades with low arsenic contents. The entire hole

is strongly anomalous in molybdenum, increasing considerably from 530 m depth with the occurrence of quartz -

chalcopyrite-molybdenite veins and becoming very strong over the last 500 m of the drill hole.

About Aldebaran Resources Inc.

Aldebaran is a mineral exploration company that was spun out of Regulus Resources Inc. in 2018 and has the same

core management team. Aldebaran acquired the Rio Grande copper-gold project located in Salta Province, Argentina

from Regulus along with several other early-stage projects in Argentina. Aldebaran also has the right to earn up to an

80% interest in the Altar copper-gold project in San Juan Province, Argentina from Sibanye Stillwater Limited. The

Altar project hosts multiple porphyry copper-gold deposits with potential for additional discoveries. Altar forms part

of a cluster of world-class porphyry copper deposits which includes Los Pelambres (Antofagasta Minerals), El Pachón

(Glencore), and Los Azules (McEwen Copper). In March 2021 the Company announced an updated mineral resource

estimate for Altar, prepared by Indepe ndent Mining Consultants Inc. and based on the drilling completed up to and

including 2020. Aldebaran’s primary focus is the Altar project with a view to discovering new zones with higher -

grade mineralization.

Sampling and Analytical Procedures

Altar follows systematic and rigorous sampling and analytical protocols which meet and exceed industry standards.

These protocols are summarized below and are available on the Aldebaran website at www.aldebaranresources.com.

All drill holes are diamond core holes with PQ, HQ or NQ core diameters. Drill core is collected at the drill site where

recovery and RQD (Rock Quality Designation) measurements are taken before the core is boxed and transported to

the Altar camp facilities, a short distance away, where the whole core is photographed under more optimum lighting

conditions and geological quick log is produced. The whole-core is then marked and sampled into geological defined,

systematic 1- to 2-metre sample intervals, unless the geologist determines the presence of an important geological

contact, which should not be crossed. The whole -core is then cut -in-half with a diamond saw blade, with half the

sample retained in the core box for future reference and the o ther half placed into a pre -labelled plastic bag, sealed

with a two plastic security zip ties, and labeled with a unique sample number. The bagged samples are then placed

into larger plastic sacks and those sacks are sealed with another plastic security zip tie and labelled for shipment. The

sacks are then placed onto wooden pallets and wrapped in plastic shrink -wrap and stored in a secure area pending

shipment to a certified ALS laboratory sample preparation facility located in Mendoza, Argentina, where the samples

are dried, crushed, and pulverized. The resulting sample pulps are sent by batch to the ALS laboratory in Lima for

geochemical assay analysis, including a 30g fire assay with an atomic absorption (AA) finish analysis for gold and a

full multi -acid digestion (4 -acid) with ICP -AES analysis for other elements. Samples with results that exceed

maximum detection values for gold are re -analyzed by fire assay with a gravimetric finish and other elements of

interest are re-analyzed using precise ore-grade ICP analytical techniques. Aldebaran independently inserts certified

control standards (Super Certified Reference Materials (SCRM’s), coarse field blanks, and duplicates into the sample

stream to monitor data quality. These standards are inserted “blindly” to the laboratory in the sample sequence prior

to departure from the Aldebaran facilities.
