ASTRA DRILLS 2,371 G/T SILVER AND 11.09 G/T GOLD OVER 0.5M - EXTENDS EAST FEEDER ALONG STRIKE AT LA MANCHURIA PROJECT, ARGENTINA

Astra Exploration Inc. has released the third batch of assays consisting of seven diamond drill holes from the phase II drill program at the La Manchuria gold and silver project in Santa Cruz, Argentina. Assays remain pending for five holes.

Highlights:

• East feeder of Main zone:
  • LMD-130: 0.5 metre grading 2,371 grams per tonne silver and 11.09 g/t gold:
    • And 0.5 metre grading 521.7 g/t silver and 2.94 g/t gold;
• West feeder of Main zone:
  • LMD-131: 0.5 metre grading 469.4 g/t silver and 6.61 g/t gold;
  • LMD-132: 0.6 metre grading 255.3 g/t silver and 5.96 g/t gold:
    • And 0.5 metre grading 612 g/t silver and 1.48 g/t gold;
  • LMD-129: 1.5 metres grading 16.4 g/t silver and 9.17 g/t gold:
    • Including 0.5 metre grading 28.6 g/t silver and 18.32 g/t gold;
• Multiple high-grade veins of key importance have been extended along strike and remain open in all directions;
• Confirmation of a continuous vein in the Eastern zone, consistently mineralized with gold and silver at a shallow vertical depth;
• The company is fully financed for a minimum of 5,000 metres expected to commence in the coming weeks.

Astra's chief executive officer, Brian Miller, commented: "The mineralized vein system at La Manchuria continues to rapidly expand in all directions with several new intercepts of high-grade silver and gold. And, because drilling has repeatedly shown that narrow veinlets near surface converge into thicker veins with depth, often with higher grades, the elevated grades encountered at these shallow depths below surface are very encouraging.

"With this set of holes, the west feeder of the Main zone has been extended along strike in both directions, and the east feeder has been extended along strike to the southeast. These veins are key high-grade structures of the Main zone, which appear to be converging with depth, forming compelling feeder zone targets. Importantly, the highest-grade intercept in LMD-130 is interpreted to be a possible extension of the Argentum vein, 220 metres along strike to the southeast of hole LMD-108A, which returned 1.4 metres grading 35 g/t gold and 8,356 g/t silver in Astra's phase I drill program."

Program details

A total of 25 drill holes were completed in late 2025 totalling 5,119 metres (see March 2, 2026, news release). The drill program focused on expanding the near-surface footprint of the system with shallow (less than 200 metres vertical depth) drill holes.

The seven drill holes reported herein were focused on the Main zone, the Eastern zone and the Basalto zone areas, each of which intersected at least one noteworthy gold and/or silver interval (Table 1).

Field crews are currently completing geophysical surveys to extend the 3-D resistivity model to the south and west beneath postmineral cover. This will provide additional drill targets for the coming 5,000-metre (minimum) program expected to commence in April.

East feeder at Main zone

Drill hole LMD-130 was designed to test the south extension of the East feeder in an unexplored area around 70 metres east of the postmineral E fault. The hole intersected several intervals of gold and silver mineralization, including a possible extension of the Argentum vein approximately 220 metres along strike to the southeast of hole LMD-108A (see June 10, 2025, news release). This interval returned 0.5 metre grading 11.09 g/t Au and 2,371 g/t Ag within andesite host rocks at a depth of 150 metres below surface. This interval is further confirmation that the andesitic sills, which were previously thought to be barren, can host high-grade gold and silver. The structure remains open in all directions.

West feeder at Main zone

The West feeder, currently 750 metres in strike length, contains some of the thickest veins and highest grades currently known at La Manchuria and is open in all directions.

Holes LMD-131 and LMD-132 were designed to test the northwestern extension of the West feeder beyond the postmineral A fault in a downthrown block, as defined by geophysics beneath the shallow cover. LMD-131 intersected West feeder mineralization between approximately 30 and 80 metres below surface within a continuous group of veins and veinlets hosted in the pyroclastic sequence, a host rock which regularly contains high-grade veins. The thickest vein returned the highest grades, with 0.5 metre grading 6.61 g/t gold and 469.4 g/t silver.

Hole LMD-132 intersected West Feeder mineralization beneath LMD-126 at about 70 metres below surface. The hole intersected several veins and veinlets containing sulphide-rich bands with visible silver sulphosalts from approximately 20 to 70 metres beneath surface. Two notable intervals include 0.6 metre grading 255.3 g/t silver and 5.96 g/t gold and 0.5 metre grading 612 g/t silver and 1.48 g/t gold. Silver and gold grades are present at the hangingwall of the West feeder vein that is steeply dipping to the southwest in this block.

The results from holes LMD-131 and LMD-132 confirm the shallow system elevation and suggest strong potential to extend mineralization at depth.

Hole LMD-129 was completed in a deeper area of the southeastern portion of the vein system below the postmineral breccia and close to LMD-107A (Table 1). Hole LMD-129 intersected West feeder mineralization at approximately 180 metres below surface after crosscutting veins from the Basalto zone near the top of the hole. The interval of 0.5 metre grading 18.32 g/t gold and 28.6 g/t silver within a banded quartz vein, is hosted in the pyroclastic sequence between andesitic sills.

Eastern zone

Three of the four holes drilled in the minimally explored Eastern zone are reported herein. These three holes were designed to test the most continuous vein outcropping at surface at this shallowly exposed vein system.

All three holes crosscut the southwest-dipping primary vein composed by a banded quartz-adularia vein associated with fault breccia, together with several veins and veinlets in the hangingwall. All of these holes reported multiple gold and silver intervals and are hosted in rhyolitic tuffs and andesitic sills (Table 1). Results at the Eastern zone increase the potential of this area to host disseminated mineralization and increase the possibility of a large structure continuing at depth.

Basalto zone

LMD-128 (previously released results) at Basalto zone revealed shallow silver-rich mineralization hosted in veins and veinlets near the surface. Hole LMD-129 confirms this vein system strikes west-northwest and dips east, with some veinlets oriented subparallel to the drill core axis.

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 multielements by ICP (ICP-AR 39). Silver (less than 200 g/t) overlimits were analyzed by gravity method (Ag4A-50). A total of 131 blanks and 154 standards (four different Au and Ag grades) were used as quality assurance/quality control for the group of 2,831 samples.

About Astra Exploration Inc.

Astra Exploration is a precious metals exploration company based out of Vancouver, B.C., 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-per-cent 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-per-cent-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 Penon.

The 100-per-cent-owned Cerro Bayo project in northern Chile is located in the Maricunga belt approximately 20 kilometres from the Refugio mine. The project hosts a high-sulphidation epithermal (HSE) plus or minus 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 endowed regions in the world for gold and copper deposits.
