A “preliminary economic assessment” or PEA means a study, other than a pre-feasibility or feasibility study, that includes an economic analysis of the potential viability of mineral resources. The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. A technical report for the PEA will be filed at www.sedar.com within 45 days of this news release, as required by National Instrument 43-101.
Key aspects and findings from this concept level study are summarized below.

Cornerstone CEO, Brooke Macdonald, said: “The PEA indicates a very financially robust project achievable with industry standard mining and metallurgical technology and benefiting from the well-established regional infrastructure. The implied value of Cornerstone’s 22.8% direct and indirect stake is between US$935M and US$1.26B depending on which of the four mine production cases is selected.”
SUMMARY:
The PEA was prepared by independent consultants Wood plc in the role of Lead Consultants with direct responsibility for the Minerals Processing, Materials Handling and Project Infrastructure components of the study, and the participation of SRK Exploration (Geology and Resource Estimation), Mining Plus (Geotechnical, Hydrogeology and Mine Planning), Knight Píesold (Environmental and Community), and Ernst and Young (Economic Analysis).
The PEA addresses findings based on the updated mineral resource (MRE # 2) announced November 2018 of 8.4 Mt Cu and 19.4 Moz Au in the Indicated category & 2.5 Mt Cu and 3.8 Moz Au in the Inferred category with the MRE across both Indicated and Inferred classifications equating to a current 2.95 Bt @ 0.52% CuEq (15.4 Mt CuEq) containing 10.9 Mt Cu and 23.2 Moz Au at 0.2% CuEq cut-off, 79% of which is in the Indicated category (by gold and copper metal content).

Additional drilling since the data cut off has not yet been modeled for MRE#3 and exploration activities on site with 10 drill rigs continues to define extensions to the mineralized envelope at Alpala, especially to the north towards Trivinio, Moran and Alpala north west at depth.
An additional MRE#3 is expected to form (along with further metallurgy, geotechnical and materials handling and storage studies) the basis for the PFS by the end of December 2019.
Ongoing work is currently focusing on exploration, geotechnical drilling, metallurgy, and materials handling & storage options, and will form the basis for the PFS.

Mine Production Scenarios
Concept level assessment of mining methods carried out as part of the PEA suggests that mining at Alpala should be conducted using low-cost underground mass mining methods such as Block Caving or Panel Caving for higher grade sections of the orebody.
Based on the November 2018 MRE #2 resource base, geological characteristics of the Alpala orebody, grade distribution, geotechnical and hydrogeological characterisation, size of the mining footprint, and other technical and economic considerations, several Block Cave mine production cases were pre-selected and assessed as part of the PEA.
These scenarios attempt to provide environmentally sound project development options aimed at optimizing the economics of the project while maximising extraction of the Alpala resource.
- Case 1 – 40 Mtpa mine production rate (life-of-mine 66 years)
- Case 2a – 50 Mtpa, staged ramp-up (life-of-mine 57 years)
- Case 2b – 50 Mtpa, fast production ramp-up (life-of-mine 55 years) – Base Case
- Case 3 – 60 Mtpa (life-of-mine 49 years)
Based on MRE #2 and as reported above in this news release, the Indicated resource at the 0.2% CuEq cut-off grade is approximately 2,050Mt averaging 0.60% CuEq, and the Inferred resource is approx. 900Mt @ 0.35% CuEq. Accordingly, the resources scheduled in the PEA block cave designs correspond to ~89% of the Indicated Mineral Resource and ~61% of the Inferred Mineral Resource.
Mineral Processing
The dominant copper mineral at Alpala is chalcopyrite (33% copper content), with lesser amounts of bornite (63% copper content). In most cases the gold is included as a particulate form in chalcopyrite, bornite or pyrite.
Metallurgical test work for the PEA was conducted based on 20 samples averaging 53kg per sample, obtained from 480m of NQ sized half core from five drill holes representing the major geological domain groups from preliminary geometallurgical models.
The testwork program for the PEA was conducted at ALS Metallurgical Laboratories in Kamloops, Canada. The laboratory program consisted of sample preparation and composite formation, comminution tests including SMC, Bond Ball Mill Work Index (BWI) and Bond Abrasion Index (AI), flotation optimization and locked cycle tests on specified composites and rougher concentrate kinetic tests.
The copper concentrator and gold recovery circuit proposed for Alpala is based on two parallel lines with one line built for Phase 1 (ramp up to 50% nameplate capacity) and a second line to reach 100% nameplate capacity in the case of the 40 and 50Mtpa mine production scenarios. Three parallel modules are considered for the 60Mtpa scenario.
Metallurgical recoveries to the chalcopyrite copper concentrate for the first 30 years of operation are estimated to range between 93.9% and 87.1% for copper and between 85.4% (high grade) and 49.4% (low grade) for gold (50Mtpa staged ramp-up) depending on mill feed grades.
Further investigations are underway to further increase copper and gold recoveries to the copper concentrate and improve gold recoveries from the pyrite concentrate.
Infrastructure
The Alpala deposit is favourably located at low altitude (600-1,800masl), with easy access via a sealed highway from the regional capital (Ibarra) some 90km by road to the south, and in proximity to water and HV power supply sources. The deep-water port at Esmeraldas is located some 180 km to the west of the project site.
Unlike some other Tier 1 porphyry copper-gold deposits which are located in the high Andes in remote locations and at very high altitude, the low elevation and mild climate year-round in the Alpala area allows exploration activities and mining operations to be conducted throughout the year.
Benefiting from these natural advantages the infrastructure requirements at Alpala are significantly reduced in comparison to many of its peers.
The likely infrastructure (on-site and off-site) requirements considered in the PEA study, include the following:
- Roads and logistics
- Concentrate pipeline from the process plant to Esmeraldas port and water return pipeline
- Tailings storage facilities options and associated infrastructure
- Surface facilities
- Underground mine infrastructure facilities
- Concentrate shipping facilities at the Esmeraldas port
- Water supply system
- Power supply system
- Communications, process control and instrumentation system
- Other Services
Marketing
Metallurgical testwork carried out to date indicates that the main product from the Cascabel project will be a high-quality copper-gold-silver concentrate with no penalty impurities and medium to high copper and gold grades plus additional silver credits, making it a desirable product for copper smelters worldwide.
Average concentrate grades over the life-of-mine are currently estimated at 26% copper, 13.2g/t gold and 49.2g/t silver. Average figures over the first 15 years of the operation are estimated at 28.2% copper, 22.1g/t gold and 65.7g/t silver. The relatively high valuable metal contents and low deleterious elements such as arsenic is expected to attract premium sales values and keep treatment and refining charges low.
Environmental and community
SolGold has conducted environmental studies in the project area using qualified practitioners for a number of years, which contributes to a defensible baseline data set. An experienced project team is leading meaningful social engagement programs to support appropriate Corporate Social Responsibility programs as part of future studies and any proposed development plans.
Current exploration activity is fully permitted and in good standing. Mine development will require the successful conclusion of an Environmental Impact Assessment and permitting from the Ministry of Environment. This is a recognized process with successful precedent in Ecuador. There are no known environmental issues that could materially impact the ability of SolGold to extract the mineral resources at the Cascabel Project. Base line environmental data has been collected at Alpala for approximately four years.
Capital and Operating Cost Estimate
Capital cost estimates for the cases assessed during the PEA range from US$2.4B to US$2.8B for pre-production Capex and from US$7.5B to US$7.8B for post-implementation and sustaining Capex.
The operating cost over the life of the project is estimated at between US$25.5B and US$25.9B depending on the production scenario. Unit C1* operating cost over the life of the project is estimated at US$0.90/lb copper after gold and silver credits (50Mtpa – Fast ramp-up base case). C1* Production Cost (average for the first 25 years, 50Mtpa – Fast ramp-up base case) – Estimated at US$0.23 per payable pound of Cu after gold and silver credits.
The capital cost estimate has been developed in accordance with Wood’s capital cost estimating procedure (PRJ-340-05) for a Conceptual study to meet the requirements of National Instrument 43-101 for a PEA and is consistent with “AACE International” cost estimating guidelines for a Class 5 estimate for the Process Industries.
The estimate accuracy range of -/+ 35% for cost inputs is defined by the level of project definition. The accuracy of the total cost estimate has been assessed to comply with the above guidelines.
Due to the long mine life, it is not expected that significant salvage values at the end of the ultimate mining resource life will be gained.
Note: * C1 Includes all site operating costs, concentrate shipping costs, smelting and refining charges, etc, but excludes royalty payments, taxes and profit share.
Economic Analysis
A discounted cash flow model was developed by Ernst & Young to evaluate the economics for the Project on a 100% project ownership basis.
The economic modeling was done on a post-tax basis and the results indicate an after-tax NPV from US$4.1B to US$4.5B based on a copper price of US$3.30 /lb and a gold price of US$1300 /lb at an 8% discount rate for the four scheduled cases. The project’s Internal Rate of Return (IRR) is estimated at between 24.8% and 26.5%, with payback periods after production commencement from 3.5 to 3.8 years.
See Figure 2 for the annual and cumulative cashflows for Case 2b: 50 Mtpa Fast ramp-up.
Sensitivity analysis was conducted on the copper and gold prices as outlined in the range in the NPV output.
The model assumes a corporate tax rate of 25% (current Ecuadorian corporate tax rate), a profit share (Labour Tax) of 15% on earnings before tax (12% government, 3% employee), a government royalty of 5% to 8% depending on the type of mineral, and a straight-line depreciation rate of 10%.
The model also includes a sovereign adjustment levy where project contributions to government (royalties, income tax, government profit share) fall below 50% of cumulative economic project benefits. Under the scenarios considered, no sovereign adjustments are required.
The basis for the Economic Analysis is from the commencement date of the project, and therefore, it does not include sunk costs which will have been incurred prior to approval to proceed to project implementation.
Risks and opportunities
Project risks and opportunities identified by the consulting team at this PEA stage of the Cascabel project include:
- SRK is not aware of any significant risks and uncertainties that could be expected to affect the reliability or confidence in the exploration information and Mineral Resource discussed herein.
As with all mineral projects, there is an inherent risk associated with mineral exploration. As such, there is no guarantee that additional drilling will grow the model or improve confidence in the model. SRK are confident the Mineral Resource can be further upgraded in confidence with more drilling and that there is some potential to grow the deposit model further.
- Mining Plus has identified that typical risks for a large block caving project (including seismicity, mud rush and cave performance) exist in this project. However, based on the available data, it is expected that these can be managed to acceptable levels through further study and operation strategies, which would be typical for a large block caving project of this nature.
Mining Plus has identified several opportunities to improve the project that should be studied in more detail in a pre-feasibility study. These include:
- Campaign mining and stockpiling to expedite further the processing of higher grade ore
- Mechanical ore sorting to remove uneconomic material from the mill feed
- Production design optimization
- Footprint layout design optimization
- Materials handling optimization
- From a mineral processing prospective Wood anticipate no obstacles being present to hinder the progressing of the project to the next phase. Recoveries and concentrate grades are representative of a copper-gold porphyry deposit of this nature with no deleterious elements reporting to the copper-gold concentrate. Wood see the following mineral processing opportunities for the project:
- Production of a gold rich pyrite concentrate that may be sold or processed on site to produce gold bullion, enhancing gold and to a lesser extent copper recovery.
- Implementation of ore sorting technology to upgrade the mill feed grade.
- The potential for the generation of additional revenue from the Cascabel Project. To determine what additional revenue may be generated, Wood recommended to investigate the following areas in the next phase of the project:
- Flotation test work: Work to date has indicated that it is possible to produce a gold rich pyrite concentrate from the first cleaner scavenger tailings stream, which could be amenable to hydrometallurgical processing to produce gold in the form of dore and to a lesser extent copper in the form of cathode copper. Initial testwork on pyrite concentrate using the Albion Process is currently underway.
- Other metallurgical testwork: That needed to assess the potential for commercial production of molybdenum concentrate from some parts of the Alpala deposit, the potential for economic recovery of magnetite ore, and the likelihood of generating revenue (or credits) from the production of sulphuric acid during the normal smelting process.
- From an infrastructure prospective, Wood anticipate no obstacles being present to hinder the progressing of the project to the next phase. During the subsequent phases there are infrastructure opportunities in areas such as TSF design where more detailed work will be required to optimize storage and reduce capital costs associated with this area.
- Knight Piesold comments indicate that there are no known environmental issues that could materially impact the ability of SolGold to extract the mineral resources at the Cascabel project as currently proposed. Mine development will require the successful conclusion of an Environmental Impact Assessment and permitting from the Ministry of Environment.
- Ernst & Young have stated that the results of the analysis show the Cascabel project to be potentially viable, warranting further study.
Conclusion and Recommendations
Based on the current mineral resource base (MRE #2) and other geological, mining, metallurgical, environmental, logistical, and financial information available for the study, this preliminary economic assessment (PEA) suggests that the Alpala copper-gold-silver deposit has the potential to support a large-scale, low-cost underground Block Cave mining operation and associated processing and project infrastructure facilities, capable of sustaining commercial production over a mine life in excess of 49 years depending on the production scenario finally adopted (55 years in the base case 2b: 50 Mtpa – Fast ramp-up).
Additional information and preparatory work required for subsequent study stages include geotechnical drilling and testing, sterilization drilling in areas currently identified for the location of infrastructure and project facilities, more advanced metallurgical testwork, additional environmental and community baseline surveys, infrastructure and logistics trade-off studies and others, much of which is currently in progress.
Based on the findings from this PEA study It is recommended that given the strong fundamentals the Cascabel Project – Alpala Deposit progresses to PFS stage.

The words “potential,” “anticipate,” “forecast,” “believe,” “estimate,” “expect,” “may,” “project,” “plan,” and similar expressions are intended to be among the statements that identify ‘Forward-Looking Statements.’ Although Cornerstone believes that its expectations reflected in these ‘Forward-Looking Statements’ are reasonable, such statements may involve unknown risks, uncertainties and other factors disclosed in our regulatory filings, viewed on the SEDAR website at www.sedar.com. For us, uncertainties arise from the behaviour of financial and metals markets, predicting natural geological phenomena and from numerous other matters of national, regional, and global scale, including those of an environmental, climatic, natural, political, economic, business, competitive, or regulatory nature. These uncertainties may cause our actual future results to be materially different than those expressed in our Forward-Looking Statements. Although Cornerstone believes the facts and information contained in this news release to be as correct and current as possible, Cornerstone does not warrant or make any representation as to the accuracy, validity or completeness of any facts or information contained herein and these statements should not be relied upon as representing its views after the date of this news release. While Cornerstone anticipates that subsequent events may cause its views to change, it expressly disclaims any obligation to update the Forward-Looking Statements contained herein except where outcomes have varied materially from the original statements.
