Astra Exploration Inc. TSXV: ASTR, OTCQX: ATEPF, Frankfurt: S3I
Introduction
Astra Exploration Inc. is a Canadian precious metals exploration company focused on discovering high grade gold and silver deposits in Argentina and Chile. Its principal asset is the La Manchuria Gold and Silver Project in Santa Cruz, Argentina, supported by two earlier stage exploration opportunities in northern Chile, Pampa Paciencia and Don Mario.
The company is primarily an exploration story rather than a development or production story. Its business model is to acquire prospective mineral properties, apply geological expertise and drilling to expand discoveries, and ultimately establish mineral resources large enough to attract development interest.
Astra’s main attraction is its exposure to high grade epithermal gold and silver systems in established mining districts.
La Manchuria sits within Argentina’s Deseado Massif, an important precious metals province that hosts producing mines such as Cerro Negro and Cerro Vanguardia. The project has a published mineral resource estimate from 2019, historical bonanza grade intercepts, and several more recent discoveries made through Astra’s drilling campaigns.
The company has demonstrated that mineralization extends beyond the original resource area. During 2025 and 2026, drilling produced multiple high grade gold and silver intercepts, including 80.54 g/t gold over 2 metres and 837 g/t silver with 3.32 g/t gold over 6.3 metres.
These results are encouraging because they suggest that La Manchuria may contain multiple mineralized structures rather than a single isolated deposit.
Astra has also expanded its La Manchuria claim package to approximately 39,000 hectares, creating considerably more regional exploration potential.
The investment thesis is built around three factors.
- First, the discovery potential of a high grade gold and silver system that remains open in several directions.
- Second, a technically experienced team with previous discoveries and direct experience working across Latin American mining districts.
- Third, a relatively small equity valuation compared with the scale of the geological opportunity the company is attempting to define.
However, this opportunity carries substantial uncertainty. Astra has not yet established a large modern mineral resource, completed a preliminary economic assessment or demonstrated that its deposits can support profitable mining operations.
Projects / Location / MRE / Grades
Project 1: La Manchuria Gold and Silver Project, Argentina (Flagship Exploration Asset)
La Manchuria is Astra’s most important project.
Located in Santa Cruz Province, southern Argentina, the property sits within the Deseado Massif, a region known for hosting substantial low sulphidation epithermal gold and silver deposits.
Several operating and historical mines are located within the surrounding district, including Cerro Negro, Cerro Vanguardia, Cap Oeste, COSE, Martha and Manantial Espejo.
The project is accessible by road and is located at approximately 650 to 700 metres above sea level, providing relatively favorable conditions for exploration compared with remote high altitude Andean projects.
In September 2026, Astra announced that it had expanded the La Manchuria claim package from approximately 5,600 hectares to 39,000 hectares through additional staking.
This larger land position is important because recent geological work has identified several regional targets beyond the original Manchuria Hill discovery.
Project ownership
Astra announced in August 2026 that it had earned an 80% interest in La Manchuria from Patagonia Gold after fulfilling more than US$3 million of exploration expenditure obligations.
The company retains an option to increase its ownership to 90% by paying US$5 million to Patagonia by August 11, 2028, subject to the terms of the agreement.
Patagonia’s retained interest is carried until publication of a qualifying resource totaling at least 1 million gold equivalent ounces in the indicated and inferred categories.
For valuation purposes, we use Astra’s existing 80% economic interest rather than assuming it completes the additional acquisition.
La Manchuria Mineral Resource Estimate
La Manchuria has a published NI 43-101 resource estimate dated September 27, 2019, originally prepared under Patagonia Gold.
This is an older resource estimate, based on an open pit concept, and does not include the full potential of Astra’s subsequent drilling campaigns.
| Resource category | Tonnes | Gold (oz) | Silver (oz) |
| Indicated | 474,000 | 39,500 | 1,969,000 |
| Inferred | 1,836,000 | 76,500 | 2,375,000 |
| Combined | 2,310,000 | 116,000 | 4,344,000 |
The original estimate reported approximately 146,300 gold equivalent ounces using its historical metal price and recovery assumptions.
The indicated portion grades approximately 2.59 g/t gold and 129 g/t silver.
The inferred portion grades approximately 1.30 g/t gold and 40 g/t silver.
The combined resource contains approximately 116,000 ounces of gold and 4.34 million ounces of silver.
This is not a particularly large resource in absolute terms, especially when compared with more advanced mining developers.
However, management believes that the original open pit resource model may not adequately represent the potential of the higher grade vein systems.
The original drilling concentrated on relatively shallow mineralization, with much of the historical drilling limited to approximately 100 to 150 metres below surface.
Astra’s current exploration strategy is focused on identifying mineralized feeder structures, testing extensions and expanding high grade zones beyond the historical resource boundaries.
Recent Drilling Results
Drilling during 2025 and 2026 has provided several significant results.
| Drill result | Gold grade | Silver grade | Interval |
| LMD 148 | 80.54 g/t | 44.5 g/t | 2.0m |
| LMD 143 | 26.23 g/t | 6.7 g/t | 2.0m |
| LMD 128 | 3.32 g/t | 837 g/t | 6.3m |
| LMD 137 | 1.46 g/t | 500 g/t | 2.3m |
| Basalto Zone, September 2026 | 4.34 g/t | 363.7 g/t | 3.0m |
| Eastern Zone, September 2026 | 3.12 g/t | 10.3 g/t | 8.0m |
These intercepts demonstrate the presence of locally exceptional precious metals grades.
The August 2026 results included 2 metres grading 80.54 g/t gold, one of the more impressive gold intercepts reported during the company’s recent drilling campaign.
At the Basalto Zone, Astra also intersected 6.3 metres grading 837 g/t silver and 3.32 g/t gold, including narrower intervals exceeding 3,000 g/t silver.
The significance is not merely the exceptional grade. The mineralized system appears to contain several parallel structures, increasing the possibility that future drilling could identify additional mineralized zones.
However, high grade drill intersections do not necessarily translate into a large resource or profitable mine.
Continuity between holes, true mining widths, dilution, metallurgy and total mineralized tonnage are equally important.
La Manchuria Grade Feel
La Manchuria has demonstrated high grade gold and silver mineralization, particularly within discrete vein structures.
The grade is one of the main attractions of this investment case.
Nevertheless, there is a meaningful difference between isolated high grade intercepts and the average grade of an economically mineable deposit.
The historical resource contains considerable lower grade disseminated mineralization. Future technical work will need to determine whether Astra can establish sufficient high grade continuity to support a selective mining operation, a larger bulk mining concept or some combination of the two.
Our assessment is that the exploration grade potential is strong, while the economically mineable grade remains unproven.
District Scale Exploration Potential
September 2026 exploration results identified several priority regional targets across an approximately 4 by 4 kilometre area.
These include La Pampa, Breccia, Floats, Solo and Creek.
La Pampa, located approximately 3 kilometres northeast of Manchuria Hill, returned surface samples grading up to 1.8 g/t gold.
The Breccia target contains a large area of hydrothermal alteration extending approximately 2 by 3 kilometres.
Several of these targets remain largely untested by drilling.
Management has outlined a follow up drilling campaign of approximately 10,000 to 20,000 metres, intended to test both extensions of the known mineralization and new regional targets.
This is where the largest exploration upside could develop.
If drilling confirms additional high grade mineralized structures across the wider district, Astra could potentially establish a substantially larger project than the one represented by the 2019 resource estimate.
At present, however, this remains exploration potential rather than established mineral inventory.
Project 2: Pampa Paciencia, Chile (Gold and Silver Exploration Optionality)
Pampa Paciencia is a wholly owned gold and silver exploration project located in northern Chile.
The property covers approximately 3,840 hectares within the Paleocene mineral belt, near established mining operations such as Spence, Sierra Gorda and El Peñón.
The district has extensive mining infrastructure, roads, power and an established mining workforce.
Astra’s exploration has identified low sulphidation epithermal veins containing attractive gold and silver grades.
Notable historical results include:
| Exploration result | Gold grade | Silver grade |
| Drill intercept, 16.3m | 2.30 g/t | 18.73 g/t |
| Including 3.75m | 7.71 g/t | 46.58 g/t |
| Surface sample | 93.3 g/t | 301 g/t |
These results demonstrate promising geological fertility.
The project also contains prospective vein structures that have received limited drilling.
Astra acquired full ownership of the project through transactions completed in 2021 and 2022.
Project assessment
Pampa Paciencia is an attractive additional exploration asset, particularly because it gives Astra direct exposure to Chile’s established mining industry.
However, the project is still at an early exploration stage.
There is no published mineral resource, feasibility study, AISC or production plan.
We consider Pampa Paciencia a source of potential future discovery value rather than a meaningful contributor to current resource based valuation.
Project 3: Don Mario, Chile (Large Gold Discovery Target)
Don Mario is a wholly owned high sulphidation epithermal gold exploration project in Chile’s Maricunga Gold Belt.
The project covers approximately 4,480 hectares and is located around 120 kilometres east of Copiapó.
The Maricunga Belt hosts several large gold and copper deposits, making it a favorable geological district for major mineral discoveries.
On October 6, 2026, Astra announced exploration results outlining a substantial gold and silver target.
The program identified a geochemical anomaly approximately 2 kilometres long and 1 kilometre wide, within a larger 2 by 2 kilometre alteration system.
Surface rock chip samples returned values up to 1.35 g/t gold, while historical drilling returned intervals of approximately 20 metres grading 0.41 g/t gold and 32 metres grading 0.38 g/t gold.
The previous drilling did not test the company’s newly identified priority targets and remains historical and unverified by Astra.
Geophysical work has also identified shallow and deeper resistivity anomalies, providing targets for a future drilling campaign.
Astra plans to undertake approximately 2,500 metres of drilling, currently targeted to commence in the first quarter of 2027.
The company owns the property subject to a 3% net smelter return royalty.
Project assessment
Don Mario provides exposure to a potentially large gold system in a district known for substantial deposits.
Its appeal comes from the scale of the alteration system and the relatively limited historical drilling.
However, the project remains speculative.
The surface geochemistry is encouraging but is not sufficient to demonstrate the existence of an economically significant deposit.
A successful maiden drilling campaign would be the first meaningful step toward establishing its commercial potential.

Risks / Catalysts / Timeline
Key Risks
| Risk | Why it matters |
| Exploration risk | High grade drill results may not translate into a sufficiently large or continuous mineral resource. |
| Resource size | The 2019 resource is relatively small, with only 116,000 oz gold and 4.34M oz silver. |
| Geological continuity | High grade epithermal veins can be narrow, irregular and difficult to model. |
| Economic uncertainty | There is no published PEA, reliable AISC, reserve estimate or economic mine plan. |
| Financing risk | Future drilling, studies and mine development may require additional funding. |
| Dilution risk | Further equity issuance could reduce existing shareholders’ ownership. |
| Country risk | Argentina and Chile have different regulatory, permitting and economic environments. |
| Project ownership | Astra owns 80% of La Manchuria, while acquiring another 10% requires an additional payment. |
| Metallurgical risk | Recoveries and commercial processing characteristics have not been sufficiently established for a development decision. |
| Commodity price risk | Lower gold and silver prices could reduce the attractiveness of future project economics. |
Catalysts
| Period | Potential milestone |
| Q4 2026 | Planned follow up drilling at La Manchuria |
| Q4 2026 | Targeting additional extensions of Manchuria Hill mineralization |
| Q4 2026 to 2027 | Potential assays from new exploration holes |
| 2027 | Regional drilling at La Pampa and other identified targets |
| Q1 2027 | Planned approximately 2,500m drilling program at Don Mario |
| 2027 onward | Continued resource expansion and geological modeling |
| Medium term | Potential updated La Manchuria mineral resource estimate |
| Medium term | Further metallurgical and technical studies, subject to exploration success |
| Longer term | Possible preliminary economic assessment if sufficient resources are defined |
The most important near term catalyst is drilling at La Manchuria.
Astra plans a substantial exploration program of approximately 10,000 to 20,000 metres, which would provide more information about the size, continuity and regional extent of the mineralized system.
Successful drilling could support a larger resource estimate and potentially improve the market’s assessment of the company.
Conversely, unsuccessful drilling or disappointing continuity could substantially weaken the investment thesis.
Expected Timeline to Full Production
There is currently no reliable published timeline for Astra to commence commercial mining or achieve full production.
The company remains focused on exploration.
| Period | Development stage | Assessment |
| 2026 | Exploration and discovery | Drilling, geological interpretation and regional target generation |
| 2027 | Planned exploration expansion | Additional drilling at La Manchuria and maiden drilling at Don Mario |
| 2028 onward | Potential technical advancement | Resource updates and economic studies, if exploration results justify them |
| Future | Mine development decision | Dependent on resources, studies, permits and financing |
| Full commercial production | Not established | No company supported production date available |
We do not believe it is appropriate to assign a specific production year without a mine development plan.
Before Astra could become a producer, it would need to demonstrate adequate mineral resources, potentially complete further economic studies, determine a suitable mining and processing method, secure regulatory approvals and obtain development financing.

All Projects Valuation Table
The following table applies FCF multiples to the hypothetical La Manchuria cash flow proxy and adds no speculative value for the other assets.
All per share values are in Canadian dollars, using 145.3 million fully diluted shares.
| FCF multiple | Gold US$6,000, Silver US$150 | Gold US$7,000, Silver US$200 |
| 10× | C$1.22 (307% upside) | C$1.52 (406% upside) |
| 15× | C$1.83 (511% upside) | C$2.28 (659% upside) |
| 20× | C$2.44 (715% upside) | C$3.04 (912% upside) |
Upside percentages are measured against the October, 2026 closing price of C$0.30.
These are theoretical, unrisked values. They must not be interpreted as achievable stock price targets.
The model assumes that the legacy resource becomes economically recoverable, that the hypothetical recoveries and cash margin can be achieved, and that no additional shareholder dilution or initial development funding adjustment is required.
None of those assumptions has been demonstrated by a technical study.
Furthermore, applying producer style FCF multiples to an exploration stage company can materially overstate current equity value because the company is not generating cash flow today.

RT Rating, Commentary
Astra Exploration deserves a place on our watchlist.
Our rating is 3 out of 5 stars.
The company has several qualities we normally look for in an early exploration investment.
It operates in established precious metals districts, has a technically experienced management team, controls attractive exploration properties and has demonstrated exceptional localized gold and silver grades.
The strongest reason to follow Astra is its people.
Diego Guido brings specialist knowledge of epithermal systems and previous discovery experience. Darcy Marud has been associated with the discoveries of El Peñón and Mercedes, while Charles Funk brings valuable experience from Vizsla Silver and Heliostar Metals.
Roberto Alarcon Bittner also provides extensive experience from Yamana, Meridian and Homestake, which is particularly useful when operating in Argentina and Chile.
This combination gives us greater confidence in the exploration strategy.
The La Manchuria project itself is interesting because the historical resource may represent only part of the broader mineralized system.
Astra has already intersected exceptionally high grades in several areas, while recent geological interpretation suggests that additional structures could remain undiscovered.
What excites us is the possibility that Manchuria Hill is only one part of a larger district.
If future drilling identifies multiple continuous high grade zones, the current resource could potentially increase substantially.
That would be the most meaningful development for shareholders.
However, there is an important distinction between a promising discovery and an investable mining development project.
Astra is still far from demonstrating a commercially viable mine.
The historical resource is relatively small, there is no detailed economic study and the company has not established a clear pathway toward production.
For this reason, we would not value Astra as if it were already a future producer.
The latest drilling results are encouraging, but we want to see more evidence of continuity, greater mineralized tonnage and an updated resource estimate that captures the potential of the new discoveries.
We also want management to preserve the relatively manageable share structure.
Exploration companies can generate substantial shareholder returns when discoveries grow faster than the share count. The opposite can happen when repeated financings dilute shareholders without creating comparable asset value.
In Astra’s case, the reported treasury and institutional support are positives, but continued drilling will inevitably consume capital.
We consider the company more attractive as a speculative discovery opportunity than as a high conviction development investment today.
The main investment threshold for us would be evidence that La Manchuria can grow into a considerably larger mineral resource with continuity, reasonable mining widths and promising economic characteristics.
A successful drilling campaign at Don Mario could also provide an additional value catalyst, although that remains a separate and earlier stage opportunity.
What it lacks is the resource scale and demonstrated economics required for a higher conviction rating.
For us, the opportunity is worth monitoring closely, particularly as the next major drill programs progress.
The question is whether Astra can convert high grade discoveries into a mineral inventory large enough to support a serious mining project.
If management can deliver that, the investment story could become much more compelling.
