The surveys aim to refine the CST target area in preparation for a winter 2024 diamond drill program. The announcement also restates the 2018 NI 43-101 mineral resource estimate for the Brabant-McKenzie Deposit. Reasoning: The company is initiating geophysical surveys to target a prospective copper zone near an existing VMS deposit, though the primary resource data provided is a restatement of a 2018 estimate. - Positive factor: commencement of geophysical surveys to target new copper stockwork - Positive factor: proximity of CST target to existing BMK deposit - Positive factor: existing high-grade VMS resource - Negative factor: resource estimate is historical \(2018\) Facts used in scoring: 23 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document restates the 2018 NI 43-101 resource estimate for the BMK Deposit. Evidence · text > current NI 43-101 resource estimate of 2.1 Mt indicated at 0.69% Cu, 7.08% Zn, 0.49% Pb, 39.6 g/t Ag, 0.23 g/t Au and 7.6 Mt of inferred at 0.57% Cu, 4.46% Zn, 0.19% Pb, 18.42 g/t Ag, and 0.1 g/t Au ## Extracted facts Stored fact records: 23.

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.
