# Astra Makes New Discovery, Hitting 6.3 Metres of 837 g/t Silver and 3.32 g/t Gold at La Manchuria Project, Argentina Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/astra-makes-new-discovery-hitting-6-3-metres-of-837-g-t-silver-and-3-32-g-t-gold--85aa261a-cb2b-448a-9488-51f2fc86f493 Original source: https://money.tmx.com/en/quote/ASTR/news/5350533045524023/astra-makes-new-discovery-hitting-6-3-metres-of-837-g-t-silver-and-3-32-g-t-gold Publisher: tmx Original announcement: 2026-03-02T11:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Astra Exploration Inc. - Ticker: ASTR - Exchange: TSX - Region: Santa Cruz, Argentina - Primary commodity: Silver - Secondary commodities: Gold - Document categories: Drill results, Other - Extracted: 2026-09-17 11:09:27 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Astra Exploration has announced a new discovery at the La Manchuria Project in Argentina, intersecting high-grade silver and gold in the newly identified Basalto Zone. Notable intercepts include 6.3m at 837 g/t Ag and 3.32 g/t Au, with a bonanza 1m sub-interval of 3,309 g/t Ag and 11.45 g/t Au. The results expand the project's footprint via a new parallel vein system. Reasoning: The announcement reports a significant new discovery in the Basalto Zone with exceptional silver grades \(837 g/t over 6.3m\) and high-grade sub-intervals, expanding the known vein field at La Manchuria. - Positive factor: High-grade silver and gold intercepts in a new zone \(Basalto\) - Positive factor: Discovery of a new parallel vein system \(Basalto Zone\) expanding the footprint - Positive factor: Structural indications of converging feeder systems at depth - Positive factor: QA/QC protocols and QP sign-off disclosed - Negative factor: Some veinlets are oriented sub-parallel to the drill core axis, potentially overstating width Facts used in scoring: 6 ## Classification and evidence **Bonanza Intercept** Polarity: positive Definition: Exceptionally high-grade zone, well above the deposit-type norm. Why it applies: The 1m interval of 3,309 g/t silver and 11.45 g/t gold is exceptionally high grade for an epithermal system. Evidence · text > 1 metre grading 3,309 g/t silver and 11.45 g/t gold **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The Basalto Zone is described as an unexplored parallel vein system 200-300m from the Main Zone, expanding the footprint. Evidence · text > unexplored parallel vein system approximately 200 to 300 metres southwest of the Main Zone, significantly increasing the size of the vein field **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release details the use of blanks, standards, and specific assay methods at Alex Stewart International. Evidence · text > A total of 131 Blanks and 154 standards \(4 different Au and Ag grades\) were used as QAQC **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The document notes that some veinlets in LMD-128 are oriented sub-parallel to the drill core axis. Evidence · text > Some of the veinlets intersected in LMD-128 are oriented subparallel to the drill core axis. ## Extracted facts Stored fact records: 6.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
