Torr Metals Delineates 2700 Metre Geophysical Anomaly Aligned with Kilometre-Scale Copper and Gold Dalvenie Trend
March 21, 2023
Vancouver, British Columbia (BC) -- (March 21, 2023) – Torr Metals Inc. (“Torr” or the "Company") (TSX-V: TMET.V) is pleased to announce the results and preliminary interpretations from a ~6.4 square kilometre (km2) induced polarization (IP) geophysical survey conducted in late 2022 over the Dalvenie Zone (Figures 1A, 1B), at the Company’s 100% owned 689 km2 Latham Project within the prolific Golden Triangle of northern British Columbia. The Dalvenie Zone is ~8 km south of the Company’s Gnat Pass Copper-Gold Porphyry deposit and is road-accessible via a 2-kilometre (km) gravel road from Highway 37.
Results from the IP survey has confirmed the general north-south trend within the Dalvenie Zone and detected multiple geophysical anomalies to a depth of 250 vertical metres (m) below the surface, that remain open, with anomalous moderate to high resistivity and chargeability signatures corresponding to at-surface copper-gold mineralization and measuring up to 500 m in width (Figures 2A, 2B). Additionally, the moderate to high chargeability and resistivity signatures are continuous along the previously defined, ~1500 metre-long, north-south striking trend of known high-grade mineralization at-surface and indicate potential for up to 1200 metres of extension to the shear structures that host gold and copper mineralization. This potential extension has been tested by extensive soil sampling in 2022 with results pending.
Malcolm Dorsey, President and CEO, commented, “We are very pleased with these results that provide invaluable geological context to identifying potential subsurface extensions to previously identified zones of at-surface high-grade copper-gold mineralization within the Dalvenie Zone. This geophysical data indicates substantial width and kilometre-scale strike-length to these anomalies that also remain open at-depth beyond 250 m, providing very compelling targets that have never been drilled. We look forward to sharing more results as we continue to uncover the significant discovery potential of the Dalvenie Zone.”
- Newly acquired 2022 IP data extend the total potential strike-length of shear structures hosting copper and gold mineralization at the Dalvenie Zone to over 2.7 km (Figures 1A, 1B).
- High to moderate resistivity and chargeability anomalies are spatially associated with multiple styles of mineralization present at surface. Historical and surface rock grab outcrop sample highlights include:
- 14.15 grams per tonne (g/t) gold (Au), 4.31% copper (Cu), and 63.1 g/t silver (Ag) (see February 9, 2023 news release) from the central Dalvenie Zone (Figure 2A).
- 2.97 g/t Au from a historical rock grab sample within the west Dalvenie Zone that contained arsenopyrite in vuggy quartz veins (Figure 2B).
- Chargeability and resistivity signatures indicate an apparent potential convergence of the central and west Dalvenie Zones, widening from a minimum ~250 metres in the south to ~500 metres in the north.
- Anomalies remail open beyond 250 metres vertical depth (Figures 2A, 2B).
- The Dalvenie Zone has never been tested by systematic drilling; Torr is well positioned to follow up on a robust set of pre-existing and newly identified targets.

Within the Dalvenie Zone the geophysical footprint is consistent over 2.7 km, providing an essential tool for understanding the subsurface geometry of the potential controls to the identified copper-gold system (Figures 1A, 1B). Rock grab samples that returned high grade copper and gold from within north-northeast trending shear structures and hydrothermal breccias are spatially coincident with linear trends of moderate to high resistivity and marginal zones of moderate to high chargeability (Figures 1A, 1B). Based on surface mapping the linear trend to resistivity anomalies is likely the result of increased silica content within shear structures and breccias that host mineralization. Areas of high chargeability are attributed to elevated sulphide content in host lithologies and bedding-parallel shear structures that dip moderately to the east. Within the northern section of the 2022 IP survey (Figure 2B) the west Dalvenie Zone contains vuggy quartz rock grab samples with elevated values in gold, arsenic, and antimony relative to copper, suggestive of a potential higher-level exposure of an epithermal system. Within this northern section the moderate to high resistivity and chargeability anomalies associated with the west and central Dalvenie Zones appear to converge, widening and deepening with a moderate plunge to the north that provides a substantial near-surface target that remains open along-strike and at-depth.
