  • Rapid After-tax payback period of 3.1 years from initial production with a 27 year mine life
  • One of the lowest capital intensities when compared to other current global copper development projects

The 2024 PEA is preliminary in nature. Current published resources for both of the Cañariaco Norte and Cañariaco Sur deposits (previously reported in News Release dated January 28, 2022) includes Inferred Mineral Resources along with a significant percentage of Measured and Indicated Resources. Inferred Mineral Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the 2024 PEA will be realized. Mineral resources that are not mineral reserves have not demonstrated economic viability.

An independent technical report for the 2024 PEA,prepared in accordance with NI 43-101,will be available under the Company's SEDAR+ profile and website on or before June 7, 2024.

For readers to fully understand the information in this news release, they should read the technical report in its entirety when it is available, including all qualifications, assumptions, exclusions and risks. The technical report is intended to be read in its entirety and sections should not be read or relied upon out of context.

An updated Corporate Presentation will be available on the Company's website at www.altacopper.com

Giulio T. Bonifacio, Executive Chair, commented "We are extremely pleased with our 2024 PEA which is well advanced as we have clearly benefited from several previous engineering studies and a wealth of experience from our external international engineering firms. This PEA will prove of great value as we advance Alta Copper to the next stage. The PEA shows that Cañariaco is clearly a Tier 1 asset that provides a long-life, large-scale copper project producing annual average copper of 158,000 tonnes per year in the first 10 years. The Cañariaco project is economically robust with considerable leverage to increasing copper prices while also possessing considerable upside through resource expansion drilling with numerous high priority drill targets identified to date at Norte, Sur and the undrilled Quebrada Verde porphyry target".

Project Description

The Cañariaco Project is situated within the Province of Ferreñafe, in the Department of Lambayeque, in northwestern Peru, approximately 700 km northwest of Lima, the capital of Peru, and approximately 102 km northeast of the city of Chiclayo. Current access from Chiclayo to the Cañariaco Project is 150 km along a paved road followed by secondary gravel roads.

The project area covers moderate elevations ranging from 2,200 to 3,600 metres ("m") above sea level. The copper deposits are situated on the eastern side of the continental divide and infrastructure will be on the top as well as both western and eastern sides of the divide. The topography varies from steep incised valleys at lower elevations to open grassy highlands at upper elevations. There is sufficient suitable land available within the concessions and close to the mining areas for the process plant, ancillary infrastructure and comingled waste rock and dry stack tailings facility.

The 2024 PEA contemplates that Cañariaco would be mined using conventional open pit mining equipment followed by crushing, SAG/ball mill grinding and flotation recovery of copper, gold and silver to a copper concentrate.

Cañariaco is estimated to have relatively low project capital and operating costs due to proximity to infrastructure and favourable natural setting with key features as follows:

  • Large scale mining and processing operation to process 120,000 tpd/43.8 million tpa with a currently planned 27 year mine life;
  • Conventional drill and blast mining, large scale electric shovels and haul trucks;
  • Conventional crushing, SAG and ball mill grinding followed by flotation recovery of copper, gold and silver to a copper concentrate;
  • Application of best practice process tailings management through comingled waste rock and filtered dry stack tailings storage;
  • Water resources available in project area exceed project requirements;
  • Low Strip Ratio life of mine of 1.33:1;
  • Power supply from existing Northern Peru power grid with connection point only 57 kms from the project; and
  • Project site located only 24 kms from existing paved highway connecting to the Pan American Highway on the west coast.

Low Capital Cost Intensity

Importantly, the Cañariaco project has low capital intensity when compared to several other global copper projects currently in the development stage. Key project attributes that reduce the capital cost include the following:

  • The mineralized material from Cañariaco Norte and Sur deposits are moderately competent with Axb of 53, and moderately soft rock with an average BWI 12.2 kWh/tonne, which enables high throughput utilizing a single comminution line consisting of one primary crusher, one large SAG mill and two ball mills whereas many projects with comparable throughput require two SAG mills and four ball mills;
  • The region receives significant annual rainfall and adequate fresh water is available at site eliminating the need for a desalination plant and pipeline from the coast;
  • Relatively close proximity to the national power grid reduces the capital intensity of power supply infrastructure;
  • Close proximity to an existing major transportation highway reduces access road construction cost and time;
  • Utilization of trucks to transport concentrate along existing highways to the loadout port eliminates the requirement for a concentrate pipeline;
  • The project site is in a sparsely populated area and there is no requirement for community relocation; and
  • Concentrate loadout through an existing port on the west coast of Peru eliminates need to construct a new loadout facility.

Source/Notes: Technical reports. Capital intensity equals total capex divided by average annual copper equivalent production. | (1) Copper equivalent production calculated using stated metal prices from each project's latest technical report.

Sustainable and Responsible Mining

The project development concept has utilized best practice technologies and will benefit from several existing external factors which will assist in making Cañariaco a very responsible, desirable and sustainable project.

The application of filtered dry stack tailings combined with comingled waste rock storage maximizes the recycling of process water and significantly reduces freshwater requirements. In addition, this technology eliminates the need for wet tailings storage and a major tailing retainment structure and reduces associated seismic risk.

Electrical power in Northern Peru is generated predominantly by hydro which is the preferred power source from ecological and carbon emissions perspectives.

Electric powered overland belt conveyors, rather than haul trucks, will transport most of the mill feed and waste rock from the mining areas to the plant as well as the comingled waste and dry stack tailings facility thereby reducing fuel consumption and CO2 emissions.

The project is located in a sparsely populated region and at elevations above major agricultural zones.

Capital, Sustaining and Operating Costs

The initial capital, expensed over the first four years of the Project, amounts to $2.2 billion. The sustaining capital over the remainder of LOM amounts to $526 million. Closure costs are estimated at $216 million. The project financial model incorporates a lease strategy for the purchase of the initial mining equipment whereby 20% of the mining fleet cost is capitalized and the remainder is carried as operating cost. Sustaining costs include construction of a crusher at the Sur deposit and related conveyor system to connect with the primary overland conveyor in year 16 prior to the start of mining operations at Sur.

Social &Environmental

Alta Copper has been active in the Cañariaco area since 2004 and since that time has developed and established a wide range of relationships with a corporate policy of respect, shared involvement and value, mutual benefit and transparency. Communications with the local communities and public authorities at all levels continues to ensure that key stakeholders are aware of the Cañariaco project status and plans, and that the Company responds to community concerns and requests.

Mining

The 2024 PEAis based on open pit mining methods with conventional drilling,blasting and material loading with large electric shovels for excavation and haulage to the primary crusher using large capacity haul trucks. Independent and dedicated high-capacity electric conveyor systems will transport plant feed from the primary crusher to the process plant and waste to the comingled waste and dry stack tailings facility.

Over the life of the Cañariaco mine, two separate deposits: Cañariaco Norte ("Norte") and Cañariaco Sur ("Sur") will be mined in separate pits, with the bulk of the plant feed coming from Norte. Mining will commence in the Norte pit which will provide 100% of the process plant feed until year 16 at which point mining operations will commence at Sur. Years 17 through 25 will see mining taking place in both Norte and Sur with variable mining rates while maintaining total annual production of 43.8 million tonnes. From year 26 through end of mine life all mining will take place in Sur.

The Cañariaco open pit mining operations will have a mine life of 27 years, operating 365 days a year with a life of mine strip ratio of 1.33:1 (including pre-stripping). The mine production plan is based on mining a total of 2.72 billion tonnes of material, comprised of 1.176 billion tonnes of plant feed and 1.548 billion tonnes of waste rock over the life of the mine. Mining operations will supply the process plant at 120,000 tonnes per day or 43.8 million tonnes per annum. During the life of mine operation, annual cash-flow will vary due to annual and forecast variations in head grade, strip ratio and metal recoveries.

The major mining equipment fleet will include nine (9) blast hole drills, five (5) 38 m3 electric shovels, two (2) 33 m3 front end loaders and thirty-eight (38) 290 tonne capacity haul trucks. A fleet of smaller loaders and trucks will be utilized for early mine access development and initial pre-stripping. Electric shovel major maintenance and mobile equipment replacement are carried in the mining costs. The moderate altitude of the Project avoids the need for de-rating of mine haul truck drive systems.

Whittle Consulting's Mine Plan Optimization

A key part of the mining plan development for this 2024 PEA included comprehensive mine plan optimization analysis by Whittle. This analysis includes a very detailed assessment of metal grades, metal prices, metal recoveries, mining and processing costs throughout the deposit, and by applying advanced computational analysis, including by the use of Whittle's proprietary Prober-E software, develops an optimized mining plan to maximize the net economic value of the mining operation. A key aspect of this mine planning strategy is that it brings forward cash flow and optimizes the net present value of the deposit. This approach involves advanced pit phasing techniques and takes advantage of variable mining cutoff grades, plant feed stockpiling and blending strategies during the life of the mine plan.

Metallurgy and Processing

The Cañariaco project comprises two copper-gold-silver porphyry deposits where the main copper species are primarily sulphides, predominantly chalcopyrite with lesser amounts of bornite and chalcocite. The Sur deposit also contains molybdenum however the levels did not warrant recovery for this 2024 PEA. Extensive metallurgical testwork programs on samples from Norte have been completed over previous years, providing an extensive metallurgical database for Norte. Resource development at Sur is at a much earlier stage than Norte and accordingly the metallurgical testwork completed for Sur is preliminary. However, the testwork results received to date from Sur are very good and comparable to the results for Norte confirming the amenability of conventional flotation recovery for both Norte and Sur.

The key metallurgical design parameters applied for process design in the 2024 PEA are as follows:

  • Mineralized material competency/hardness: Drop Weight Test Parameter Axb 53 (75th percentile), Bond Ball Mill Work Index 12.2 kWh/tonne (75th percentile), moderately competent and moderately soft
  • Grind size P80 for flotation feed: 200 microns
  • Metallurgical recoveries (life of mine): Copper 88.2 %, Gold 63%, Silver 53%
  • Copper concentrate: 26% Copper, 3.7 g/t Gold, 74 g/t Silver.

Mine haul trucks will transport plant feed material to the crushing station where they will dump the material directly into a large gyratory crusher. From the crusher, plant feed material will be conveyed to a live stockpile ahead of the grinding circuit. Plant feed will be drawn from the stockpile and fed to a single 12.8 m diameter by 8.2 m EGL (Effective Grinding Length) SAG mill. SAG mill discharge will be screened to remove oversize pebbles which will be crushed in pebble crushers and returned to the SAG mill feed. SAG mill screen undersize product will be fed to two parallel 8.5 m diameter by 11.4 m EGL ball mills operating in closed circuit with cyclones to produce floatation feed at 80% minus 200 microns. The floatation circuit will comprise of rougher and cleaner flotation stages, with rougher concentrate regrinding prior to cleaner flotation. Cleaner concentrate will be dewatered using a thickener and pressure filters, then conveyed to the concentrate storage building to await transportation to the port for loadout and shipping to offshore smelters.

Waste and Tailings Handling

The Cañariaco process flowsheet has included Comingled Dry Stack tailing technology for waste rock and tailings placement. This technology is considered as "Best Practice" and is seeing more application within the global mining industry. The technology offers three key benefits:

  • increases process water reclaim and recycling;
  • eliminates the requirement for wet tailings containment dams and eliminates related seismic risk,
  • reduces the size of tailing containment system footprint. Dry stack tailings treatment utilizes pressure filters to dewater process tailings to low moisture content with recovered water recycled to the process. The dry tailings filter cake produced are transported by belt conveyor to the tailings management facility where they can be placed or "stacked" with waste rock as a stable pile within the tailings facility. Combining the dry tailings sands with waste rock within the same pile enhances the overall stability of the pile and eliminates the need for two separate facilities.

Cautionary Note to US Investors

We advise U.S. investors that this news release uses terms defined in the 2014 edition of the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) "CIM Definition Standards on Mineral Resources and Mineral Reserves", as incorporated by reference in Canadian National Instrument 43-101 "Standards of Disclosure for Mineral Projects", for reporting of mineral resource estimates. These Canadian standards, including NI 43-101, differ from the requirements of the United States Securities and Exchange Commission (SEC) as set forth in the mining disclosure rules under Regulation S-K 1300. Regulation S-K 1300 uses the same terminology for mineral resources, but the definitions are not identical to NI 43-101 and CIM Definition Standards.
