Blueberry project - copper porphyry potential
Vizsla owns the Blueberry Project free and clear of any obligations, royalties, payments or expenditures. The 20,265-hectare Blueberry Project lies in a prolific copper-porphyry trend and is adjacent and immediately south of the Stars project owned by ML Gold Corporation (“ML Gold”). The project area has a significant mining heritage with past production at nearby mines such as Equity Silver, Bell Copper, Endako and the very recently closed Huckleberry mine. The Blueberry Project was assembled by the NorthBase team with extensive experience in copper exploration and development, including the mine geology at the Huckleberry open pit copper mine.
Recent drilling on the adjacent Stars project has resulted in a new discovery in the area. Highlighted drill results from the Stars project include: 204 metres at 0.5% copper equivalent grade (“CuEq”) including 40.2 metres at 1.02% CuEq (ML Gold Press Release 2018-02-28) and 405.38 metres at 0.26% CuEq (ML Gold Press Release 2018-11-8).
Figure 1: Blueberry Exploration Targets:
Importantly, property geology is believed to extend southward into the Blueberry Project area based on interpretations of regional geophysical datasets. The Blueberry property is approximately ten times larger than the Stars project and is underlain by prospective geology with numerous magnetic high anomalies in an under-explored till covered plain. Most importantly, recent detailed stream sediment survey results on the Blueberry Project are encouraging, with several anomalies highlighting large till covered drainages with associated magnetic high anomalies that may contain new, hidden porphyry copper deposits.
About the Blueberry Project:
The Blueberry property is located ~60 kilometres southwest of the town of Houston, British Columbia. The property falls within the jurisdiction of the Omineca Mining Division. The property benefits from ample access through a network of resource roads on the property.
Geological information on the Blueberry project is limited due to a lack of historical geological data. However, given the proximity of the adjacent Stars property, which has detailed information on record, and interpretations of regional geophysical datasets, the geology of the Blueberry is likely similar. At the Stars property (from Lane, 2008): “The main lithological units present within this area consist of volcanic flows and tuffs of the Lower Jurassic Telkwa Formation and sandstones, shales and siltstones of the Lower Cretaceous Skeena Group (Desjardins et al., 1990). The northern portion of the property is bounded by plugs of the Early Jurassic Topley Suite (Robertson, 1999). A granodiorite (Gray, 2002) to quartz monzonite (Robertson, 1999) stock largely covers the central portion of the property. This stock is thought to resemble members of the Bulkley Intrusive Suite; a suite which includes regionally intrusive rocks commonly found associated with mineral showings.
2018 Exploration on the Blueberry Project:
Longford Exploration Services Ltd. executed a fall 2018 stream sediment sampling program on the Project. The twenty-two-day program collected 182 stream sediment samples. This phase of the project was used as a primary pass analysis to vector in future exploration for potential copper porphyry mineralization.
Numerous zones of interest have been identified that correlate to anomalous copper, zinc, lead, silver and gold in the stream sediments collected. Additional airborne and groundwork is required to check on these anomalous zones of metal mineralization. Areas above/upstream of the samples with high geochemical results will be checked for visual mineralization, mapped and sampled. The zones of interest correlate significantly with highs on the residual total magnetic field regional geophysics demonstrating that doing higher resolution airborne geophysics would be helpful in targeting metal mineralization on this property.
 Disclosure: Mineralization hosted any adjacent properties is not necessarily representative or indicative of mineralization hosted on the Blueberry Project.
