NEWS RELEASE

Aldebaran Reports All Remaining Holes From 2021/2022 Altar Drill Program

VANCOUVER, CANADA ( September 7 , 2022 ) – Aldebaran Resources Inc. (“ Aldebaran” or the “Company ”)

(TSX-V: ALDE, OTCQX: ADBRF) is pleased to report the remaining drill holes from the 2021/2022 drill program

at the Altar copper gold project located in San Juan, Argentina. Holes QDM-22-47B, QDM-22-48B, QDM-22-49 and

QDM-22-50B were designed to test for extensions of porphyry mineralization and provide sufficient drill hole density

to support a maiden 43 -101 mineral resource calculation at the Radio Porphyry target . Drill holes QDM-22-45U,

QDM-22-45L and QDM-22-45D were designed to test the areas around the high-grade gold intercept from the QDM

Gold deposit intercepted in QDM-21-45 (see news release dated February 24, 2022). The holes drilled at the Radio

Porphyry successfully extended the mineralized footprint and indicated the system remains open in various directions.

The holes following up on the previously reported high -grade gold intercept hit mineralization but were unable to

reproduce the previous long runs of higher-grade. However, QDM-22-050B drilled through the western portion of the

QDM Gold deposit and intercepted another high-grade gold intercept, providing more evidence that the QDM Gold

deposit remains open in several directions and has the potential to host multiple high-grade mineralized structures.

John Black, Chief Executive Officer of Aldebaran, commented as follows: “The holes that were drilled into Radio

Porphyry continue to demonstrate the continuity of the system. With this information in hand, we will begin to evaluate

whether we have completed enough drilling to move to a resource update for Radio Porphyry or whether additional

drilling will be required. The holes that tested the QDM Gold deposit are encouraging as we now have multiple

occurrences of quite attractive grade gold mineralization throughout the deposit. We have yet to determine the

controls on mineralization, however, it appears the higher grades are structurally controlled. We have now reported

all the results from the 2021/2022 drilling campaign and are already preparing to return to the Altar project in the

coming months to begin the 2022/2023 drill campaign, which will largely be focused on testing the very large and

encouraging geophysical anomaly we have delineated at the Altar Central and Altar East deposits.”

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 project is an ea rly-stage

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

values are CuEq % = Cu % + Au g/t * 0.6805 + Ag g/t * 0.00875 + Mo ppm / 3000 and AuEq g/t = Au g/t + Ag g/t / 77.7778 + Cu % * 1.4694 +

Mo ppm / 2041.7092. TD = Total Depth.

Discussion of Results

QDM-22-045U / QDM-22-045D / QDM-22-045L

Holes QDM-22-045U (135 degrees azimuth / -63 degrees dip / 301.4m depth), QDM-22-045D (135 degrees azimuth

/ -75 degrees dip / 407.5m depth) and QDM-22-045L (119 degrees azimuth / -68.5 degrees dip / 373.3m depth) were

collared on the same drill pad as the previously released QDM-21-045.

The objective of this set of three shallow drillholes was to test the extension in all directions of the high-grade gold

interval intersected in hole QDM -22-045. All the drillholes intersected rocks with very similar characteristics. The

holes begin in intervals of multistage breccia units including a strongly altered magmatic breccia with in a dacite

porphyry matrix, which is crosscut by several pulses of rock milled matrix breccias. Alteration in the upper portion is

characterized by strong sericite- pyrite-sphalerite-quartz-tourmaline assem blages associated with high gold -zinc

mineralization that pervasively replac es the rock and is associated with the occurrence of veins within discrete

corridors where the alteration is intense and the sulphide content increases. The holes transition into the andesitic

volcanic-sedimentary host rock package of early Miocene age, crosscut by narrow dacite dykes. The intensity of

alteration is variable on the lower portion of these holes, with a notable increase in pyrite content associated with

intense quartz-tourmaline alteration.

QDM-22-047 / QDM-22-047B

Drillhole QDM-22-047 was lost prematurely at 172.4 m depth due to drilling-related operational problems. Twin hole

QDM-22-047B was collared a few meters away and drilled up to a depth of 1,241.5 m. Both holes were drilled at -75

degrees dip and 00 azimuth to test for the eastern extension of the higher-grade mineralization found in hole QDM-

21-043.

QDM-22-047B encountered a leached and oxidized zone up to 207 m depth, followed by a long run with moderate

grades of copper-gold mineralization associated with the occurrence of moderate “k feldspar-biotite-magnetite-quartz-

chalcopyrite-bornite” potassic alteration with weak quar tz-chalcopyrite-pyrite-magnetite veining, overprinted by

weak “green sericite- chlorite-chalcopyrite-pyrite / quartz -tourmaline-sericite” assemblages. Potassic alteration

increases to moderate-strong from 450 m depth and up to 1,177 m.

Potassic alteration progressively decreases from 1 ,177 m depth until the bottom of the hole, accompanied by the

occurrence of increasing quartz-anhydrite-molybdenite-chalcopyrite-pyrite veins.

QDM-22-048 / QDM-22-048B

Drillhole QDM-22-048 was lost prematurely at 165.5 m depth due to drilling-related operational problems. Twin hole

QDM-22-048B was collared a few meters away and drilled up to a depth of 1,449.3 m. Both holes were drilled at -70

degrees dip and 138 degrees azimuth. The purpose of these holes was to test for the vertical extension of higher-grade

mineralization found in QDM-21-034 and QDM-22-043.

The top third of drillhole QDM -22-048B cuts through a package of andesitic rocks . The upper 150 m of the hole

displays moderate to strong sericite -pyrite-tourmaline alteration, associated with gold mineralization typical of that

observed at the QDM Gold deposit. From 150 m to 565 m, the rocks display strong potassic alteration accompanied

by moderate vein stockworks of quartz-pyrite-chalcopyrite-magnetite / q uartz-green sericite -chalcopyrite-pyrite

±bornite / quartz-pyrite-molybdenite-chalcopyrite.

The hole intersected a late-mineral porphyry unit from 565 m to 865 m depth which displays weak to moderate potassic

alteration and weak quartz veining. It is believed this late porphyry unit has a sub- vertical geometry and is much

narrower than the intercepted width in the drill hole. At 917 m, the hole goes back into the andesite wall rocks where

mineralization continues associated with quartz-pyrite-molybdenite-chalcopyrite vein stockworks with moderate

potassic alteration.

QDM-22-049

Drillhole QDM-22-049 was collared on the southern edge of the QDM Gold Zone. The hole was drilled at -73 degrees

dip and 40 degrees azimuth, reaching a final depth of 1,086.8m. It was intended to drill perpendicular to holes QDM-

22-045 and QDM-22-048B infilling an area with no previous drilling. Ultimately the hole deviated over 100 m from

its original target due to operator issues.

QDM-22-049 intersected a dacite porphyry starting from surface down to 81 m depth, before entering a homogeneous

and thick sequence of andesitic fragmental and massive porphyritic rocks. From 902 m depth until the bottom of the

hole, several porphyry dykes were encountered. The top 130 m of the hole displays sericite alteration associated with

pyrite. Below 130 m depth, alteration increases progressively from weak to moderate potassic alteration associated

with weak to moderate quartz-chalcopyrite-pyrite-molybdenite veining. Mineralization increases around 700 m depth

and progressively increases towards the bottom of the hole.

QDM-22-050 / QDM-22-050B

Drillhole QDM-22-050 was lost prematurely at 306.1 m due to drilling-related operational problems. Twin hole QDM-

22-050B was collared a few meters away and drilled up to a depth of 898.4 m. The hole was drilled at -77 degrees dip

and 225 degrees azimuth. The main objective of these holes was to test for the northwestern extension of the Radio

Porphyry system and the western extension of the QDM Gold deposit. The hole ended prematurely due to heavy

snowfall that forced the shutdown of the 2021/2022 campaign.

Drillhole QDM-22-050B intersected a dacite porphyry unit from surface to 560 m depth which is crosscut by several

hydrothermal breccias containing attractive gold grades , and by minor late magmatic -hydrothermal breccias

displaying in most cases rock-milled matrix. From 560 m to the end of the hole, the hole was predominantly in andesite

volcanic wall rocks.

Very strong sericite alteration with associated pyrite and galena predominates in the top 560 m of the hole however,

below this the alteration weakens and there is very little mineralization until approximately 700 m depth when the

potassic alteration and mineralization increases until the end of the 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 Independent Mining Consultants Inc. and based on the drilling completed up to and

including 2020.

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 other 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.
