# Corvus Gold Intersects Gold-Silver System in Initial East Bullfrog Scout Holes and Soil Survey, North Bullfrog Project, Nevada Canonical Atlas analysis: https://atlas-staging.minestarters.com/news/corvus-gold-intersects-gold-silver-system-in-initial-east-bullfrog-scout-holes-a--bb0d1b7b-bc37-4213-95f4-26c80f070859 Original source: https://money.tmx.com/en/quote/KOR/news/67310106/corvus-gold-intersects-gold-silver-system-in-initial-east-bullfrog-scout-holes-a Publisher: tmx Original announcement: 2015-09-16T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Corvus Gold Inc. - Ticker: KOR - Exchange: TSX - Region: Nevada - Primary commodity: Gold - Secondary commodities: Silver - Document categories: Drill results, Resource update - Extracted: 2026-08-23 20:20:44 UTC Narrative sentiment: 0.40 · Bullish ## Minestarters Atlas summary Corvus Gold has reported positive initial scout drilling results from the Alunite Hill target within the North Bullfrog Project in Nevada. The results confirm the presence of a gold-silver system in a large, previously untested area, supported by encouraging soil survey anomalies. Reasoning: Initial scout drilling confirms the presence of a gold-silver system in a previously untested zone, providing a significant exploration vector. - Positive factor: First confirmation of gold-silver systems in a large untested target area - Positive factor: Presence of mineralization at depth - Positive factor: Soil survey anomalies correlate with structural zones - Negative factor: Intercepts are low-grade - Negative factor: Reported drill intercepts are not true widths Facts used in scoring: 22 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: Initial scout drilling into the previously untested Eastern Steam-heated Zone. Evidence · text > initial two scout drill holes in the new and previously untested Eastern Steam-heated Zone **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: Release details laboratory \(ALS Chemex\), use of standards, blanks, and duplicates. Evidence · text > Quality control is monitored by the insertion of blind certified standard reference materials and blanks **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: Significant portion of the reported resource is in the Inferred category. Evidence · text > an inferred resource of 1.48 Mt ## Extracted facts Stored fact records: 22.

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.
