NEWS RELEASE

Astra Intersects 1,286 g/t Silver and 9.0 g/t Gold Over 3.1 Metres; Extends

High-Grade at Depth and Along Strike at La Manchuria Project, Argentina

Highlights:

• Hole LMD-121: 3.1metres grading 1,286 g/t silver and 9.0 g/t gold including

o 0.9metres grading 3,102 g/t silver and 25.1 g/t gold

• Hole LMD-118: 1.4metres grading 16.4 g/t gold and 81g/t silver including

o 0.6metres grading 34.7 g/t gold and 180 g/t silver

• Confirmation of high-grade mineralization in the northwest extension of the West Feeder

Zone – five additional step-out holes pending along northwest strike

• Confirmation of high-grade veins hosted in andesitic sills, previously interpreted to be a

barren host rock

Vancouver, British Columbia – February 10, 2026 – Astra Exploration Inc. (TSX -V: ASTR,

OTCQB: ATEPF, FSE: S3I) (“Astra” or the “Company”) is pleased to announce the first batch of

assays consisting of six DDH holes from the Phase II drill program at the La Manchuria Gold and

Silver Project in Santa Cruz, Argentina. Assays remain pending for 19 holes.

Astra’s CEO, Brian Miller commented:

“New sources of high-grade veins continue to emerge at La Manchuria. Drilling has revealed the

system is open along strike in both directions, at depth below previous drilling, laterally in new

parallel structures, and now we can definitively add additional host rock units to th at list. We’ve

proven that high-grade gold and silver exist beyond nearly every previously interpreted constraint,

which bolsters our original thesis that La Manchuria has the potential to host a multi-million-ounce

high-grade deposit.”

Miller continues:

“It is important to keep in mind that these results are from a small portion of the property, which

itself now has unconstrained potential – and there are numerous regional targets which show

potential for expansion, all centralized within a large project area of spectacular fertility. We are

eager to commence with the fully -funded second half of Phase II to further expand the system.

Applying the knowledge we’ve gained by opening the system locally will improve our odds of

success and reduce dilution as we grow the system regionally.”

Program Details

A total of 25 drill holes were completed in late 2025 totaling 5,119 metres (see Dec 1, 2025 news

release, “Astra Provides Progress Update on Phase II Drill Program at La Manchuria Gold and

Silver Project, Argentina”). The drill program focused on expanding the near-surface footprint of

the system with shallow (<200m vertical depth) drill holes . The Company plans to commence

geophysical surveys in February and commence with the second half of Phase II (~5,000 metres)

in March 2026.

Drill Results and Discussion

The six drill holes reported herein were focused primarily on the Main Zone area (Figure 1), each

of which intersected at least one noteworthy gold and/or silver interval (Table 1). The regular

occurrence of both gold and silver grade demonstrates the fertility of the system even at shallow

system depths.

shows approximate location of long section in Figure 2.

West Feeder at Main Zone

The West Feeder contains some of the thickest veins and highest grades currently known at La

Manchuria. LMD-121 and LMD-118 extended the high-grade vein at depth and along strike to the

northwest, respectively (Figure 2). LMD-121 returned a significant mineralized interval, beginning

at 224.4m downhole (~170m vertically below surface) of 3.1 metres grading 9.04 g/t Au and 1,286

g/t Ag, including a higher-grade sub-interval of 0.9 metres grading 25.14 g/t Au and 3,102 g/t Ag.

The interval is comprised of two, banded, quartz–adularia–sulphide veins hosted within an

andesitic sill. This interval is of particular importance, being the first intercept of vein hosted, high

grade gold and silver intersected within andesitic host rocks. The andesitic sill is approximately

25 metres thick and is underlaid by a pyroclastic sequence (Figure 3) which is a common host to

high-grade veins. This revelation adds new potential for high-grade veins at depth.

results are in grams per tonne (g/t). Photo is the sample with 0.9m grading 25.14 g/t Au & 3,101.7 g/t Ag. Hole LMD-

121 deviated upwards and intersected the vein approximately 25m above the targeted depth.

LMD-118 intersected several quartz–adularia–sulphide banded veins and veinlets hosted within

pyroclastic rocks and an andesitic sill (Figure 4) located in an upthrown structural block west of

the Main Zone (Figure 2). The most significant interval was hosted in an andesitic sill underlain

by pyroclastic sequence (similar to LMD-121) and returned 1.4 metres grading 16.44 g/t Au and

81 g/t Ag, including a higher-grade interval of 0.6 metres grading 34.67 g/t Au and 180 g/t Ag

within a quartz–adularia–amethyst banded vein (see Figure 4 photograph). This structure

represents a 60 metre down dip step out of mineralization intersected in LMD-113 which

returned 1.3 metres grading 17.3 g/t Au and 61 g/t Ag.

results are in grams per tonne (g/t). Photo is the sample with 0.6m grading 34.67 g/t Au & 180.30 g/t Ag.

East Feeder at Main Zone

LMD-119, LMD-120 and LMD-116 were designed to test, from north to south, the eastern

portion of the Main Zone, referred to as the East Feeder, which is now interpreted to dip toward

the southwest. All holes intersected low-sulphidation epithermal (LSE) veins and veinlets,

returning multiple gold and silver intervals along their lengths (Figure 1 and Table 1). These

results further support and refine the shallow bulk disseminated mineralization model for the

Main Zone.

LMD-120 and LMD-119 tested the northern extension of the East Feeder beneath post mineral

cover and intersected at least three zones of shallow LSE-style mineralization with anomalous

precious metal values (>1 g/t AuEq). These results indicate that the mineralized system remains

open to the north within a downthrown structural block and warrants further drill testing at depth,

particularly within underlying pyroclastic host rocks.

LMD-116 intersected multiple massive to banded quartz–chalcedony–sulphide veins and

veinlets between 7 metres and 211 metres downhole, all hosted within rhyolitic tuffs. The most

significant intersection of 1.1 metres grading 2.77 g/t Au and 41.9 g/t Ag corresponds to the

down-dip projection of the Argentum vein at approximately 150 metre vertical depth. LMD-116

demonstrates that shallow disseminated mineralization within the East Feeder remains open in

all directions.

Basalto Zone

LMD-117 was the first drill hole of the current program to test the structurally complex Basalto

Zone and was designed to evaluate mineralization below Phase I drill hole LMD-105. LMD-117

intersected two zones of mineralization associated with shallow-level banded quartz–

chalcedony–amethyst veins and veinlets hosted within an andesitic sill. Anomalous grades

within the andesitic sills are encouraging, giving the possibility for higher grades in the

underlying pyroclastic host rocks.

Sampling Procedures

Drill samples consisted of HQ core which were split in half, sampled, bagged, and tagged by

Astra´s geological team and then delivered to the Alex Stewart International Argentina

laboratory in Mendoza. Drill samples were prepared with P5 code and then analyzed with fire

assay for gold (Au4-50) and multi-elements by ICP (ICP-AR 39). Silver (>200 g/t) over-limits

were analyzed by gravity method (Ag4A-50). A total of 131 Blanks and 154 standards (4

different Au and Ag grades) were used as QAQC for the group of 2,831 samples.

About the Company

Astra Exploration Inc. is a precious metals exploration company based out of Vancouver, BC that

is actively building a portfolio of high -quality projects in some of the most important mining

jurisdictions in Latin America.

The La Manchuria gold -silver project in Santa Cruz, Argentina , over which Astra has an

option to acquire 90% interest from the owner, Patagonia Gold Corp , is a high -grade gold and

silver low sulphidation epithermal (LSE) deposit located in the prolific Deseado Massif which hosts

multiple world-class LSE precious metals deposits including Cerro Vanguardia and Cerro Negro,

Santa Cruz, Argentina.

The 100% owned Pampa Paciencia gold and silver project in northern Chile is located in the

Paleocene mineral province in proximity to such major operating mines as Spence and Sierra

Gorda. The project shares several important geological similarities to other Paleocene LSE gold-

silver deposits including Faride and El Peñón.

The 100% owned Cerro Bayo project in northern Chile is located in the Maricunga belt

approximately 20 km from the Refugio Mine. The project hosts a high sulphidation epithermal

(HSE) +/- porphyry gold system with similarities to the Salares Norte deposit to the north in the

same belt. The Maricunga belt is one of the most en dowed regions in the world for gold and

copper deposits.
