Vancouver, British Columbia – June 25, 2025 – Astra Exploration Inc. (TSX-V: ASTR, OTCQB:
ATEPF, FSE: S3I) (“Astra Exploration” or the “Company”) is pleased to announce additional
results from the Company’s maiden drill program at the La Manchuria Project, located in the
prolific Deseado Massif of Santa Cruz, Argentina.
Astra’s CEO, Brian Miller commented:
“Astra’s first drilling program at La Manchuria indicates a much larger vein system than previously
recognized. Significantly, it has many intervals of high gold and silver grades with exceptional
grades of up to 199.3g/t gold (LM-107A) and 8,356g/t silver (LM-108A – see June 10, 2025 news
release). The drill program also confirmed the Company’s geologic model, and that mineralization
extends to depth and to the southeast, northwest, and southwest. Particularly noteworthy is the
extension of high-grade veins of the Main Zone to the southeast beneath the post-mineral cover.
We are currently finalizing plans for a fully-funded follow-up drill program that will look to continue
growing the La Manchuria district.”
Drilling Program
A total of 11 diamond drill holes (DDH), totaling 2,468 meters were completed in the Phase I drill
program at La Manchuria . The drilling tested four different target zones identified by the As tra
exploration team (see May 21, 2025 news release ). The results reported herein are from seven
drill holes completed to the southeast and northwest of the Main Zone and from the Eastern Zone
(Figure 1 and Table 1).

Gold and silver results are in grams per tonne (g/t).

Drilling Results and Discussion
Southeast of Main Zone
Drill holes LMD-107A, LMD-110, LMD-111 and LMD-115 were designed to test the south-eastern
extension of the Main Zone . Previous drilling had intercepted mostly post-mineral cover rocks
without intersecting any epithermal veining. The Astra geologic model correctly predicted that the
post mineral cover required deeper drilling. Drill hole LMD-107A successfully intersected the Main
zone high-grade veins approximately 75 meters southeast of any previous intersections and hole

LMD-110 indicates that the post mineral cover thins to the southeast.
Drill hole LMD -107A (Figure 2) tested the strike extension of previously intersected epithermal
veins below 110 m eters of the post-mineral breccia cover unit. The hole returned one of the
highest gold grade intercepts to date on the project, with 0.6 m of a banded quartz and black
sulphides vein (Photo 1) grading 199.3 g/t Au and 228 g/t Ag at a downhole depth of 189.5 meters.
This vein is part of a wider zone of precious metal-rich veins and veinlets within a 7.5-meter-wide
zone of sub parallel veins and veinlets (see Figures 1 & 2).
Drill holes LMD-110 and LMD-115 intersected veining in the andesitic rocks, which returned no
significant assay results. Hole LMD-111 returned two intervals (3.0 meters grading 0.9 g/t Au and
11 g/t Ag at 106 meters downhole, and 3.0 meters grading 0.37 g/t Au and 59 g/t Ag at 185 meters
downhole).
The current drilling demonstrates the structural complexity of the southeast extension and the
control of lithology on grade distribution. Additional drilling is planned for this area to better define
the distribution and variation of high-grade mineralization.

Northwest of Main Zone
Drill hole LMD-113 was designed to explore for new veins to the northwest of the Main Zone. The
hole successfully intersected a group of four mineralized structures that could represent either
the northwestern projection of the Main Zone or new parallel veins to the west of the Main Zone.
The drilling intersected shallow veins with several high-grade mineralized interval s that remain
open at depth and along strike:
• 12 m with 0.78 g/t Au and 97 g/t Ag at 8 m downhole depth that represents the upper flaring
portion of a continuous veinlet structure previously defined by four earlier drill holes ( see
Figure 3), and open at depth
• 1.0 m with 6.2 g/t Au and 11 g/t Ag at 35 m downhole depth
• 1.4 m with 1.1 g/t Au and 306 g/t Ag at 57 m downhole depth, and
• 1.3 m with 17.3 g/t Au and 61 g/t Ag at 63.8 m downhole depth
The style of veining in the last two intercepts suggest they may represent two branches of a single,
continuous structure, which remains open along strike and to depth. The branches may merge
into a thicker, more cohesive zone that will be followed up by future drilling.

reported LMD-109) drill results.
Eastern Zone
Drill holes LMD-112 and LMD-114 tested the Eastern Zone.
LMD-112 was drilled 40 meters to the west of LM-099-D (which returned 3.95 meters @ 16.0 g/t
Au and 42 g/t Ag) with the objective of testing the depth extent of this mineralization. LMD-112
intersected several new mineralized veins, breccias and veinlets that together returned 4.0 meters
of 7.6 g/t Au and 0.5 g/t Ag at 30 meters down hole and also intersected (in the andesitic rocks
the down dip extension of mineralization intersected in LM -099-D) 3.0 meters of 3.8 g/t Au and
25 g/t Ag at a drill depth of 99.0 meters.
LMD-114 intersected some veining in andesitic rocks with no significant assay results. The
Eastern Zone has been tested with only five holes and has returned intervals of > 5g/t AuEq in
four of these. The Eastern Zone requires significant additional drilling to fully define the limits
and extents of mineralization.
Next Steps
With the success of the initial drill program that extended known high -grade mineralization and
discovered new sub parallel high-grade veins, the Company is finalizing plans to follow up with a
Phase II drill program. With a current treasury of approximately $2 million Astra is well-funded to
continue to grow the La Manchuria epithermal vein system.
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) and gold (>100 g/t) over-limits
were analyzed by gravity method (AuAg4A-50). 48 Blanks and 58 Standards (3 different Au and
Ag grades) were used as QAQC for the group of 1,146 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, 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.
