Recording date: 5th March 2026

Astra Exploration (TSXV: ASTR) is a junior precious metals company with a focused two-country portfolio in Chile and Argentina, and a clear near-term strategy centred on its La Manchuria gold-silver project in Santa Cruz province. Following a strong PDAC 2026, the company is well positioned heading into what could be a transformational period of exploration.

La Manchuria is a low sulphidation epithermal system with a dual-target structure. Near surface, the company has confirmed an expanding bulk disseminated gold-silver system — one that has grown with every drill programme conducted to date. Deeper in the system lies the primary prize: a potential high-grade feeder zone, the kind of structure that drives the most significant epithermal discoveries in Patagonia. Astra has been methodically building toward testing that target, beginning with near-surface drilling to establish scale and validate the geological model before committing capital to deeper holes.

Two programmes have now been completed, totalling 7,500 metres across 36 holes. Of the 25 holes drilled in the second programme, 13 have been released with results. Twelve remain pending from the laboratory and are expected to be published by the end of March 2026. These represent a near-term, defined news pipeline that does not require the company to raise capital or commence new fieldwork to deliver.

The third programme — another 5,000 metres — is set to begin within approximately one month. Astra holds roughly $4 million in cash, sufficient to fund this programme in full. The budget was structured at the time of the company's $6.2 million raise to ensure exactly this kind of operational continuity. The third programme will begin to shift focus toward deeper targets, moving the company closer to the high-grade feeder discovery scenario that underpins its long-term investment case.

Argentina's operating environment has also improved significantly. Under President Milei's administration, permitting has accelerated and foreign investment capital is flowing into the country at a pace not seen in recent years. Santa Cruz province permits year-round drilling, removing the seasonal constraints that limit many other jurisdictions and enabling a consistent cadence of results throughout 2026.

Beyond Argentina, Astra holds two Chilean projects — Pampa Paciencia, adjacent to two operating copper mines, and a high sulphidation target in the active Maricunga belt — that provide strategic optionality without requiring meaningful near-term capital. Pre-drill work is planned at Cerobio in Chile in the coming weeks, with the potential to unlock value through partnership or joint venture as the belt attracts renewed attention following Chile's improved political backdrop.

For investors, the proposition is straightforward: a funded explorer with an expanding near-surface discovery, a high-grade feeder thesis yet to be tested at depth, a defined catalyst schedule across the next 60 to 90 days, and a macro tailwind from both gold prices and an improving Argentine investment climate. Astra enters the next phase of its programme with momentum, capital, and a story that is only beginning to register with the wider market.
