# Grid Metals’ atomic-clock cesium resource in Manitoba ranks second globally Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/grid-metals-atomic-clock-cesium-resource-in-manitoba-ranks-second-globally--2be620dc-4449-4ae0-8597-73f0d09b73b7 Original source: https://www.northernminer.com/news/grid-metals-atomic-clock-cesium-resource-in-manitoba-ranks-second-globally/1003895367/ Publisher: northernminer Original announcement: 2026-10-01T14:05:10.000Z Analysis by Minestarters Atlas Atlas analysis published: 2026-10-01T18:48:46.260Z Atlas analysis updated: 2026-10-01T18:48:46.260Z - Company: Grid Metals - Ticker: GRDM - Exchange: Unavailable - Region: Manitoba - Primary commodity: Cesium - Secondary commodities: Lithium - Document categories: Resource update - Extracted: 2026-10-01 18:48:47 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Grid Metals has outlined an initial measured resource for its Lucy South deposit at the Falcon West property in Manitoba. The resource contains 51,500 tonnes grading 2.58% Cs2O and 1.47% Li2O, including a high-grade pollucite zone. Reasoning: The announcement of an initial measured resource for the Lucy South deposit represents a major de-risking milestone for Grid Metals. - Positive factor: High-grade pollucite zone reported - Positive factor: Resource is entirely classified as measured - Positive factor: Significant scale for an early-stage developer - Positive factor: Proximity to infrastructure and power grid Facts used in scoring: 4 ## Classification and evidence **Measured Resource** Polarity: positive Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves. Why it applies: The entire Lucy South resource is classified as measured. Evidence · text > Lucy South’s entire resource is classified as measured **QP/CP Signed** Polarity: positive Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience. Why it applies: The document mentions the resource is based on drilling but does not explicitly name a signing QP/CP in the text provided. Evidence · text > The resource is based on drilling completed between 2012 and 2026. ## Extracted facts Stored fact records: 4.

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.
