World Copper Provides Exploration and Development Update on the Zonia Copper Oxide Project, Central Arizona

FOR IMMEDIATE RELEASE…Vancouver, British Columbia: World Copper Ltd. (“World Copper” or the “Company“; TSXV: WCU, OTCQX: WCUFF, FRA:7LY0) announces that it has completed an internal technical review of the exploration and development potential of the Zonia Copper Oxide Project (“Zonia” or the “Zonia Project“), located in the Walnut Grove Mining District, Yavapai County, Arizona, United States.  The Company acquired Zonia in January 2022; a decision made in part based on Zonia’s strong 2018 preliminary economic assessment (the “PEA“).

Key Highlights

An internal technical review confirms three significant potential growth drivers for the Zonia Project:

  • Resource expansion targets adjoining the existing Zonia resource provide an opportunity to enlarge the outlined mineralization through step-out drill programs.
  • A significant porphyry exploration target, “Zonia Norte”, to the northeast of the main resource, previously undrilled, represents potential for discovery of a new deposit separate from the main resource, potentially similar in size, but within the overall Zonia land package.
  • An update of the most recent Preliminary Economic Assessment, to include mineralized material that was excluded from the last concept, and to enlarge the project and assess Zonia’s development potential under current market conditions.

Nolan Peterson, CEO and President of World Copper Ltd commented “With the Zonia Project in Arizona and our flagship Escalones project in Central Chile, World Copper now controls two significantly de-risked copper oxide resources that set us apart from most junior copper exploration companies.  The Zonia Project in particular has established itself as a near-term project with a strong development case and timelines that synergize well with our overall strategy.  Since acquiring Zonia our team has focused in on understanding its potential to build upon its already robust economics.  We will be restarting exploration and development at Zonia in the coming months, and I look forward to providing updates as our work progresses.”

World Copper has assessed Zonia’s potential to host significantly more copper mineralization and is currently working on exploration drilling targets along the southwest to northeast long-axis of the Zonia deposit and below the existing resource (Figure 1) as well as a compelling surface rock sample copper and molybdenum geochemical anomaly coincident with a manganese low anomaly located approximately two kilometres north-northeast of the established resource (Zonia Norte, Figure 2).  In addition to the exploration targets identified, World Copper intends to update the  PEA, which is dated April 17, 2018, with an effective date of March 22, 2018, and was prepared by Global Resource Engineering Ltd. for Cardero Resource Corp., which reported mining methods and an economic base case based on USD $3.00/lb copper (a copy of the  technical report with respect to the PEA is available on the Cardero Resource Corp. SEDAR profile at www.sedar.com).  The mineral resource statement used for the PEA will also be updated as part of this process, to reflect recent copper prices.

Zonia Project Resource Expansion Potential

World Copper has compiled and evaluated historical surface and subsurface geological, geochemical, and geophysical data currently available for the main Zonia deposit.  Previous explorers focused on the near-term production potential of the Zonia deposit and constrained the mine plan model to a scale that would allow all mine infrastructure to be on private patented land claims, where the mine permit process is comparatively shorter.  Historical surface exploration data and subsurface drilling data support significant potential to expand the existing resource through infill and step out drilling within and adjacent to the current resource. 

The Zonia deposit is outlined by an IP chargeability high and has an associated surface copper-molybdenum rock geochemical high with a coincident manganese low (Figures 1 and 2).  This anomalism extends beyond the current drill footprint and warrants step out drilling on all sides.  Furthermore, additional drilling is necessary at depth below the current pit to (i) infill widely spaced mineralized intercepts and (ii) identify additional mineralization capable of pulling the pit to greater depths.

A review of the geology and existing block model will be made to evaluate areas of additional mineralization internal to the existing model and to identify specific targets for expanding resources with follow-up drilling.

Zonia Norte Exploration Potential

The largest potential for a new discovery at Zonia is to the north-northeast of the current open pit and resource, where a large (2.5 x 1.5 kilometres) coincident copper-molybdenum-manganese geochemical anomaly has been identified (Zonia Norte; Figure 2).  Historical surface rock geochemical sampling has delineated a copper-molybdenum anomaly that is spatially coincident and similar in size/shape with a broad zone of manganese depletion consistent with typical porphyry-copper mineralization.  This anomaly is situated 1.5 kilometres to the north-northeast of the Zonia deposit, which exhibits the same pattern of geochemical anomalism and is comparable in size to the northeast target.  It is significant that the anomaly is open to the north where outcrops are covered by post-mineral cover.  This large geochemical footprint is interpreted to represent a second porphyry centre.  Nearby historical drill holes indicate the area is deeply weathered and copper-oxide mineralization is present. 

Zonia Exploration Plans

Exploration efforts are ongoing at Zonia.  Additional mapping and detailed sampling is required to understand controls on mineralization at the northeast end of the Zonia open pit, where several high-grade historical copper showings need to be fully understood.  The showings lie on a trend that links the main deposit to the new drill target to the northeast.  The Zonia Norte porphyry target was fully permitted by the previous operator and is drill-ready once the permitting process is re-started.  The drill programme comprises 18 shallow near-surface oxide targeting holes totaling over 5,000m (18,000 feet).  Further mapping over the target and adjacent areas are planned.  High-grade historical copper occurrences (Copper Crown and others) along the north and east edges of the Zonia Norte anomaly will be mapped and sampled as part of the ongoing target delineation exploration program at Zonia.  These occurrences of high-grade copper have geological similarities to volcanogenic massive sulphide and/or replacement-type deposits.

Zonia Project Development Program

World Copper plans to update the PEA in order to: (i) have it reflect current market conditions; (ii) include the full extent of the available resource; (iii) explore different sizes and concepts as part of a strategic review of the asset; and (iv) incorporate additional drill and geological data, as warranted.  The PEA used USD $3.00/lb copper for a base case scenario producing 92.6 million tons of leachable material over an 8.6-year mine life.  At a copper price of $3.00/lb, the Zonia Project shows an after-tax NPV@6% of $225 million, an NPV@8% of $192 million, an NPV@10% of $163 million, and an IRR of 29.0%; the payback period is 2.89 years.  The PEA concluded the Zonia Project is most sensitive to copper price which is an important consideration for improving the economics.  The updated PEA will be part of a broad strategic review of the Zonia Project and is a low-cost and high-reward study that is expected to positively impact Zonia’s development outlook.  

The PEA is considered preliminary in nature, contains numerous assumptions and includes Inferred Mineral Resources that are considered too speculative, geologically, to have the economic considerations applied that would enable them to be classified as Mineral Reserves.  There is no certainty that the results of the PEA (or any update thereto) will be realized.  No Mineral Reserves have been estimated for Zonia.  Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.  Inferred Mineral Resources are that part of the Mineral Resource for which quantity and grade, or quality are estimated based on limited geologic evidence and sampling, which is sufficient to imply but not verify grade or quality continuity.  Inferred Mineral Resources may not be converted to Mineral Reserves.  It is reasonably expected, though not guaranteed, that most Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.  Mineral Resources are captured within an optimized pit shell and meet the test of reasonable prospects for economic extraction.  All dollar amounts in the preceding paragraph are reported in US dollars unless otherwise noted.

Cautionary Note to United States Investors

World Copper prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of U.S. securities laws.  Terms relating to mineral resources in this news release are defined in accordance with NI 43-101 under the guidelines set out in CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the Canadian Institute of Mining, Metallurgy and Petroleum Council on May 19, 2014, as amended (“CIM Standards”).  The U.S. Securities and Exchange Commission (the “SEC”) has adopted amendments effective February 25, 2019 (the “SEC Modernization Rules”) to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934.

As a result of the adoption of the SEC Modernization Rules, the SEC will now recognize estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources”, which are defined in substantially similar terms to the corresponding CIM Standards.  In addition, the SEC has amended its definitions of “proven mineral reserves” and “probable mineral reserves” to be substantially similar to the corresponding CIM Standards.

U.S. investors are cautioned that while the foregoing terms are “substantially similar” to corresponding definitions under the CIM Standards, there are differences in the definitions under the SEC Modernization Rules and the CIM Standards.  Accordingly, there is no assurance any mineral resources that World Copper may report as “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had World Copper prepared the resource estimates under the standards adopted under the SEC Modernization Rules.

In accordance with Canadian securities laws, estimates of “inferred mineral resources” cannot form the basis of feasibility or other economic studies, except in limited circumstances where permitted under NI 43‑101.
