Phase Two Program At The La Manchuria Project

VANCOUVER – Astra Exploration Inc. reported on 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.
CEO, Brian Miller, said, “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 that 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.
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.”
A total of 25 drill holes were completed in late 2025 totaling 5,119 metres. 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.
The six drill holes focused primarily on the Main Zone area, each of which intersected at least one noteworthy gold and/or silver interval. The regular occurrence of both gold and silver grade demonstrates the fertility of the system even at shallow system depths. 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. 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 which is a common host to high-grade veins. This revelation adds new potential for high-grade veins at depth.
LMD-118 intersected several quartz-adularia-sulphide banded veins and veinlets hosted within pyroclastic rocks and an andesitic sill located in an upthrown structural block west of the Main Zone. 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. 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.
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. 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.
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.
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.
