Electric Royalties Ltd. (TSX-V: ELEC) (OTCQB: ELECF) is pleased to announce the signing of a binding letter agreement with World Copper Ltd. (TSXV: WCU) (OTCQB: WCUFF) (FRA: 7LY0) to acquire a 0.5% gross revenue royalty on the wholly owned Zonia Copper Oxide Project in Arizona, US in exchange for C$1,550,000 cash and 2,000,000 common shares of the Company. The Company will also have the right , for a period of 15 months after closing of the Transaction, to acquire a further 0.5% GRR on the Zonia Project for C$3,000,000 cash consideration. In addition, the Company will have an option, to acquire a 1% GRR on the Zonia Norte deposit, adjacent to the Zonia Project, for C$3,000,000 cash, at any time during a period of 24 months from the date that World Copper publishes an initial technical report in respect of the Zonia Norte deposit which is prepared in accordance with National Instrument 43-101 and which contains an estimate of Inferred Mineral Resources.
The 2,000,000 common shares will be subject to voluntary escrow which provides that the common shares will be subject to a hold period of 6 months. The Transaction noted herein is subject to completion of due diligence, approval of the TSX Venture Exchange and other customary conditions.
Brendan Yurik, CEO of Electric Royalties commented, “As a royalty company, we seek to acquire development assets that that have a clear path to production. The Zonia Copper Oxide Project is a near-term copper oxide development project in an attractive mining jurisdiction, Arizona, with a clear path to production.
“Zonia has had an extensive amount of drilling and a significant resource estimate of over 500 million pounds of copper with potential for further resource growth. At recent and forecast long-term copper prices, the Zonia Project has robust economics, a compelling case to bring it to production, and a team experienced in project delivery. As the project sits entirely on private patented land in Arizona, there is potential for a permitting and start of operations timeline of under four years. Due to the extensive amount of work already carried out on the project, World Copper’s management estimates that C$5 million is sufficient to advance the project to feasibility stage within the next two years. As the world transitions toward a net-zero economy, the clean energy technologies enabling this shift will be metal intensive. Copper demand is projected to exceed supply by five to eight million metric tons by the end of the decade1. We’re very excited to partner with World Copper’s management team and believe that Zonia is well positioned to meet this demand.”
Zonia Project Royalty Acquisition Highlights
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.
Zonia Project Overview
History
The Zonia Copper Oxide Project in central Arizona has been held under private ownership for almost 100 years and has undergone extensive historical exploration, metallurgical studies and mine development planning. Much of the mineralized area was pre-stripped during previous open-pit mining operations in 1966, at which time, 17 million tons were mined with 7 million tons stacked on heap leach pads, producing cement copper until 1975. The property has been drill-tested with almost 700 drill holes (60,000 metres (m)). This high-density drilling covers 30% of the property and defines the current resource estimate, reducing technical risk on the deposit. Mineralization is mostly open to the northeast, providing considerable opportunity to grow the resource.
Geology
The Zonia deposit is a highly oxidized, supergene enriched, porphyry deposit, located at surface. Oxidation of the original chalcopyrite mineralization and younger secondary supergene chalcocite has been pervasive and deep, extending down over 250 m in the central part of the deposit. The original pyrite-chalcopyrite sulphide mineralization underwent oxidation and remobilization which resulted in development of chalcocite-rich lenses. This supergene mineralization was subsequently oxidized and partly remobilized due to uplift, erosion, and lowering of the water table, resulting in a large deposit of in-situ and transported copper oxide mineralization. Oxide copper deposits such as Zonia are particularly suitable to low-cost heap leaching extraction methods, and also offer the potential to generate pure copper cathode on site, without the need for costly transportation of concentrate to smelters.
Mining and Processing
The Zonia project would employ open pit mining with a conventional copper acid heap leach system. The mineralized material would be crushed in a three-stage crushing circuit to a nominal P80 size of 25 millimetres (mm). The crushed material would be agglomerated with acid containing solutions using either raffinate or fresh sulphuric acid, and then be delivered to the heap via conveyors then stacked in 10-m lifts with a radial stacker. The heap is designed to contain up to 10 lifts for a maximum height of 100 m, each with an interlift liner.
The SX circuit consists of two extraction stages and one stripping stage using a conventional mixer/settler arrangement. The electrowinning (EW) circuit consists of two parallel banks of 50 poly-cement cells with 1 m2 cathodes. The plated copper cathodes are stripped using a mechanized stripping system after being washed. Copper cathodes are then sampled and bundled for shipment.
Good copper extractions were achieved from the majority of the metallurgical samples at Zonia, and range from 59% to 81% in a 91-day locked cycle column leach test (excluding the high sulphide and low grade samples). The copper extraction from the master composite sample, with a nominal P80 size of 25 mm, was 77.8%. The overall copper extraction based on the total copper assay (% TCu) for the deposit is estimated to be between 71% and 75%. For pit optimization, copper recovery has been assigned based on mineral type with copper oxide minerals at 73%, secondary copper sulphides at 70% and primary copper sulphides at 0%.
Exploration
There is ample opportunity to increase the mine life through successful exploration. There is a compelling target to the northeast of the deposit location. The Zonia Norte target is defined by surface rock sampling and forms a copper-molybdenum anomaly approximately 1,500 m x 2,500 m.

About Electric Royalties Ltd.
Electric Royalties is a royalty company established to take advantage of the demand for a wide range of commodities (lithium, vanadium, manganese, tin, graphite, cobalt, nickel, zinc and copper) that will benefit from the drive toward electrification of a variety of consumer products: cars, rechargeable batteries, large scale energy storage, renewable energy generation and other applications.
Electric vehicle sales, battery production capacity and renewable energy generation are slated to increase significantly over the next several years and with it, the demand for these targeted commodities. This creates a unique opportunity to invest in and acquire royalties over the mines and projects that will supply the materials needed to fuel the electric revolution.
Electric Royalties has a growing portfolio of 19 royalties, including one royalty that currently generates revenue. The Company is focused predominantly on acquiring royalties on advanced stage and operating projects to build a diversified portfolio located in jurisdictions with low geopolitical risk, which offers investors exposure to the clean energy transition via the underlying commodities required to rebuild the global infrastructure over the next several decades towards a decarbonized global economy.
