The survey delineated a large high-resistivity batholith interpreted as a potential porphyry system, providing a vector for follow-up drilling at the Gnome and Semlin targets. Reasoning: The ZTEM geophysical survey successfully identified a large intrusive body that provides a structural and geological framework for a potential porphyry system, corroborating existing geochemical anomalies. - Positive factor: Successful delineation of a large high-resistivity batholith - Positive factor: Strong geophysical, geochemical, and geological convergence - Positive factor: Identification of district-scale porphyry potential - Positive factor: Presence of multi-element soil anomalies - Negative factor: Targets are currently underexplored and require deeper drilling Facts used in scoring: 7 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The survey identifies new geophysical targets \(Gnome and Semlin\) to guide future exploration. Evidence · text > designed to refine geological understanding and guide targeting for Phase 2 **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The project is located in the Quesnel terrane, a major copper-producing belt with nearby Tier 1 mines. Evidence · text > located in the Quesnel terrane, British Columbia's primary copper-producing belt, which hosts Teck Resources' Highland Valley Mine ## Extracted facts Stored fact records: 7.
