Vizsla Copper Corp.

Woodjam Copper-Gold Project

Overview

The 90,163 hectare property Woodjam Project is a large, well-endowed copper-gold porphyry exploration and development project located in elephant country in the prolific Quesnel terrane in South-Central British Columbia. Historical mineral resource estimates for three deposits on the Project lands total approximately 1.7B lbs of copper and just under 1M ounces of gold in the Southeast, Deerhorn and Takom deposits. 

Located 50 kilometers east of the community of Williams Lake in an area characterized by a low elevation, gently undulating landscape, the project is easily accessed year-round by a network of logging and forest service roads.  Geologically, the Woodjam Project is located within the highly prospective Quesnel Terrane – a large regional depositional belt commonly dominated by alkalic volcanic units and related volcaniclastic lithologies. The Quesnel terrane hosts both alkaline and calc-alkaline porphyry copper+/-gold+/-molybdenum deposits, including the Copper Mountain, New Afton, Highland Valley, Gibraltar, Mount Polley, Mount Milligan and Kemess mines.

Phase I Exploration

In 2023 Vizsla Copper completed a total of 7,599 metres in 18 holes, successfully extending the Deerhorn and Takom deposits while also intersecting the strongest mineralization to date at the Megaton zone. Click here for phase I results.

Historical Work

To date, six zones of porphyry mineralization (Megabuck, Deerhorn, Takom, Three Firs, Southeast, and Megaton) have been identified at the Woodjam Project by drilling (95,092 meters in 281 holes since 2009 and a further 114 holes, 30,092 meters predominantly from 1998). These six mineralized zones form a cluster approximately 5 kilometers in diameter. The Megabuck and Takom Zones were occurrences documented previous to 1998 but largely untested until after 2003 while the larger Southeast Zone and Deerhorn Zone were discovered in 2007 and 2008, respectively. In 2012, the Three Firs Zone was discovered and in 2012 the Megaton Zone was discovered. Historical mineral resource estimates are summarized in the table below.

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.  Only a limited amount of drilling has been completed since that time, but the most recent results from 2020 and 2021 are spectacular.  Highlights are summarized in the table below.

  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.
