Proven Porphyry District
Situated within a prolific copper-gold district that hosts major mines and deposits, including Mount Polley, Gibraltar, Mount Milligan and Kemess.
Strong Regional Access
Located approximately 55 km from Williams Lake with access to existing infrastructure and exploration corridors.
Well-Serviced Access in a Proven Mining District
Highway Access
Located approximately 55 km from Williams Lake via a paved provincial highway.
Established Road Network
Low-relief terrain and an established logging-road network provide reliable access.
Regional Infrastructure
Proximity to Williams Lake supports exploration logistics, personnel and services.
Historical Estimates
Across Three Deposits
Woodjam adds a large, tangible estimate base to Vizsla Copper's district-scale B.C. copper portfolio. Of the multiple mineralized zones identified across the property to date, only three - Southeast, Deerhorn and Takom - carry a historical estimate, prepared in 2013 using data collected through modern drilling and sampling methods. Because that work predates current CIM resource classification standards, it cannot be treated as a current mineral resource. Vizsla Copper nonetheless considers the underlying data reliable, and it continues to inform how the company evaluates and prioritizes the broader Woodjam district today.

Much of the drilling and other exploration work on the property was completed by Gold Fields Ltd. under Joint Venture agreements with the historical property owners until Gold Fields sold their interest to Woodjam Consolidated Copper Corp. in 2015.
Multiple Targets Across
One Copper-Gold System
To date, six zones of porphyry-related mineralization have been identified by drilling at Woodjam: Megabuck, Deerhorn, Takom, Three Firs, Southeast and Megaton. These zones form a cluster approximately 5 km in diameter.
Beyond the known mineralized zones, ongoing geophysical work has identified additional discovery opportunities, including the Great Plains target, where a broad 2 km by 2 km chargeability anomaly is being drill-tested in 2026.
The Megabuck and Takom zones were occurrences documented previous to 1998, but largely untested until after 2003, while the larger Southeast and Deerhorn zones were discovered in 2007 and 2008, respectively. In 2012, the Three Firs and Megaton zones were discovered.
Reported drill intervals are downhole core lengths. True widths are unknown unless otherwise stated.
HISTORICAL ESTIMATE
SOUTHEAST
Southeast is the largest of the Woodjam deposits with a historical estimate. Drilling completed in 2024 intersected broad intervals of copper-gold mineralization within the Southeast zone.
HISTORICAL ESTIMATE
DEERHORN
Deerhorn is a gold-copper mineralized zone with a historical estimate. Current drilling is designed to evaluate potential extensions to the southwest.
HISTORICAL ESTIMATE
TAKOM
A copper-gold deposit within the Woodjam mineralized cluster, with 2023 drilling successfully extending mineralization along its eastern side.
EXPLORATION TARGET
GREAT PLAINS
A previously untested 2km by 2km chargeability anomaly located 4 km south of the Southeast deposit and interpreted to share a similar geological setting.
DRILL-DEFINED MINERALIZED ZONE
THREE FIRS
A near-surface copper-gold zone where 2024 drilling intersected a new mineralized breccia, providing a potential vector toward another porphyry centre.
DRILL-DEFINED MINERALIZED ZONE
MEGATON
Previous drilling identified broad porphyry-related copper mineralization, including the strongest results reported from the zone to date during the 2023 program.
DRILL-DEFINED MINERALIZED ZONE
MEGABUCK
An established copper-gold porphyry zone within Woodjam’s cluster of six drill-defined mineralized systems, with additional geophysical and geological targets identified for follow-up.

4. The Historical Estimates are considered historical in nature and as such are based on prior data and reports prepared by previous property owners. The reader is cautioned not to treat them, or any part of them, as current mineral resources or reserves. The Company has determined the Historical Estimates are reliable given that they are based on data collected with modern drilling and sampling methods and were completed the Former JV Partner, and relevant to be included here in that they simply demonstrate the mineral potential of the Woodjam Project. A qualified person has not done sufficient work to classify the Historical Estimates as current resources and Vizsla Copper is not treating the Historical Estimates as current resources. Significant data compilation, re-drilling, re-sampling, data verification and a site visit may be required by a qualified person before the Historical Estimates can be classified as a current resource. There can be no assurance that any of the historical mineral resources, in whole or in part, will ever become economically viable. In addition, mineral resources are not mineral reserves and do not have demonstrated economic viability. Even if classified as a current resource, there is no certainty as to whether further exploration will result in any inferred mineral resources being upgraded to an indicated or measured mineral resource category. The Historical Estimates relating to inferred mineral resources were calculated using prior mining industry standard definitions and practices for estimating mineral resource and mineral reserves. Such prior definitions and practices were utilized prior to the implementation of the current standards of the Canadian Institute of Mining for mineral resource estimation, and have a lower level of confidence.
