Introduction
Ecuador is located on the copper-gold rich and under-explored northern section of the Andean Copper Belt. The well explored southern portion is renowned as the production base for nearly half of the world’s copper (Figure 1). SolGold’s strategy to become a tier 1 copper and gold producer through systematic exploration continues to yield exciting results. Follow up exploration has focussed on 12 priority projects identified across SolGold’s 75 granted regional concessions.
With 12 priority projects now recognised, ongoing exploration by SolGold technical teams is focussed on advancing these priority projects with a view to progress to drill testing as soon as possible. SolGold’s high success rate has been achieved by operating multiple field teams comprising 42 Ecuadorean geologists in regional exploration, led by highly experienced national geologists and applying the exploration discovery and appraisal blueprint developed over the last 4 years at Alpala.
SolGold recently released details of its PEA on the Alpala Deposit in Cascabel to the south, showing a base case NPV of US$4.2 bn over a 55 year mine life, on a contained resource of 23.2 m oz gold and 10.9 mt (24 bn lbs) of copper at $1400/oz gold and $3.30/ lb copper.

ABOUT SOLGOLD
SolGold is a leading exploration company focussed on the discovery and definition of world-class copper and gold deposits. In 2018 SolGold’s management team was recognised by the “Mines and Money” Forum as an example of excellence in the industry, and continues to strive to deliver objectives efficiently and in the interests of shareholders. SolGold is the largest and most active concession holder in Ecuador and is aggressively exploring the length and breadth of this highly prospective and gold-rich section of the Andean Copper Belt.
Dedicated stakeholders
SolGold employs a staff of over 560 and at least 98% are Ecuadorean. This is expected to grow as the operations at Alpala, and in Ecuador generally, expand. SolGold focusses its operations to be safe, reliable and environmentally responsible and maintains close relationships with its local communities. SolGold has engaged an increasingly skilled refined and experienced team of geoscientists using state of the art geophysical and geochemical modelling applied to an extensive data base to enable the delivery of ore grade intersections from nearly every drill hole at Alpala. SolGold has 86 geologists, of which 11% are female, on the ground in Ecuador looking for copper and gold.
About Cascabel and Alpala
The Alpala deposit is the main target in the Cascabel concession, located on the northern section of the heavily endowed Andean Copper Belt, the entirety of which is renowned as the base for nearly half of the world’s copper production. The project area hosts mineralisation of Eocene age, the same age as numerous Tier 1 deposits along the Andean Copper Belt in Chile and Peru to the south. The project base is located at Rocafuerte within the Cascabel concession in northern Ecuador, an approximately three hour drive on sealed highway north of Quito, close to water, power supply and Pacific ports (Figure 1).
Having fulfilled its earn-in requirements, SolGold is a registered shareholder with an unencumbered legal and beneficial 85% interest in ENSA (Exploraciones Novomining S.A.) which holds 100% of the Cascabel concession covering approximately 50km2. The junior equity owner in ENSA is required to repay 15% of costs since SolGold’s earn in was completed, from 90% of its share of distribution of earnings or dividends from ENSA or the Cascabel concession. It is also required to contribute to development or be diluted, and if its interest falls below 10%, it shall reduce to a 0.5% NSR royalty which SolGold may acquire for US$3.5m.
Over 189,984m of diamond drilling has been completed on the project. With numerous rigs currently active on the project, SolGold produces up to approximately 10,000m of core every month. The Cascabel drill program is currently focussed on extending and upgrading the status of the Alpala Resource, as well as further drill testing of the rapidly evolving Aguinaga prospect. Drill testing of the Trivinio target has commenced, whilst the numerous other untested targets, namely at Moran, Cristal, Tandayama-America and Chinambicito, are flagged for drill testing as overall program demands allow.
The November 2018 Alpala MRE update, dated 15 November 2018, was estimated from 68,173 assays. Drill core samples were obtained from total of 133,576m of drilling comprising 128 diamond drill holes, including 75 drill holes comprising, 34 daughter holes, 8 redrills, and 11 over-runs, and represents full assay data from holes 1-67 and partial assay data received from holes 68 to 75. In contrast, the Dec 2017 Maiden MRE was estimated from 26,814 assays obtained from 53,616m of drilling comprising 45 drill holes, including 10 daughter holes and 5 redrills.
The November 2018 Alpala updated Mineral Resource Estimate (MRE) totals a current:
o | 2,050 Mt @ 0.60% CuEq (at 0.2% CuEq cut-off) in the Indicated category, and 900 Mt @ 0.35% CuEq (at 0.2% CuEq cut-off) in the Inferred category. |
o | Contained metal content of 8.4 Mt Cu and 19.4 Moz Au in the Indicated category. |
o | Contained metal content of 2.5 Mt Cu and 3.8 Moz Au in the Inferred category. |
Investors should consult the technical report dated 3 January 2019 for a detailed account of the assumptions on which the estimates were based as well as any known legal, political, environmental and other risks that could materially affect the development of the resources.
Getting Alpala advanced towards development
The resource at the Alpala deposit boasts a high grade core which, in the event of the construction of a mine, is targeted to facilitate early cashflows and an accelerated payback of initial capital. SolGold is currently investigating development and financing options available to the company for the development of Cascabel on reaching feasibility.
The results of the PEA were published on 20 May 2019, highlighting the following key aspects:
Ø | Net Present Value (“NPV”) estimates range from US$4.1Bn to US$4.5Bn (Real, post-tax, @ 8% discount rate, US$3.3/lb copper price, US$1,300/oz gold price and US$16/oz silver price) depending on production rate scenario. |
Ø | Internal Rate of Return (“IRR”) estimates range from 24.8% to 26.5% (Real, post-tax, US$3.3/lb copper price, US$1,300/oz gold price and US$16/oz silver price) depending on production rate scenario. |
Ø | Pre-production Capex estimated at approx. US$2.4B to US$2.8B, and total Capex including life of mine sustaining Capex of US$10.1B to US$10.5B depending on production rate scenario. |
Ø | Payback Period on initial start-up capital – Range from 3.5 to 3.8 years after commencement of production depending on production rate scenario. |
Ø | Preferred Mining Method – Underground low-cost mass mining using Block Cave methods applied over several caves designed on two vertically extensive Lifts. |
Full results and all details of the PEA are available in the Company’s market release of 20 May 2019.

The Company recognises that the term “World Class” is subjective and for the purpose of the Company’s projects the Company considers the drilling results at the growing Alpala Porphyry Copper Gold Deposit at its Cascabel Project to represent intersections of a “World Class” deposit. The Company considers that “World Class” deposits are rare, very large, long life, low cost, and are responsible for approximately half of total global metals production.
“World Class” deposits are generally accepted as deposits of a size and quality that create multiple expansion opportunities, and have or are likely to demonstrate robust economics that ensure development irrespective of position within the global commodity cycles, or whether or not the deposit has been fully drilled out, or a feasibility study completed.
Standards drawn from industry experts (1) Singer and Menzie, 2010; (2) Schodde, 2006; (3) Schodde and Hronsky, 2006; (4) Singer, 1995; (5) Laznicka, 2010) have characterised “World Class” deposits at prevailing commodity prices. The relevant criteria for “World Class” deposits, adjusted to current long run commodity prices, are considered to be those holding or likely to hold more than 5 million tonnes of copper and/or more than 6 million ounces of gold with a modelled net present value of greater than USD 1 Billion.
The Company and its external consultants prepared an initial mineral resource estimate at the Cascabel Project in December 2017. Results are summarised in Table B attached.
The Mineral Resource Estimate was completed from 53,616m of drilling, approximately 84% of 63,500m metres drilled as of mid-December 2017, the cut-off date for the maiden resource calculation. There remains strong potential for further growth from more recent drilling results, and continue rapid growth of the deposit.
Any development or mining potential for the project remains speculative.
Drill hole intercepts have been updated to reflect current commodity prices, using a data aggregation method, defined by copper equivalent cut-off grades and reported with up to 10m internal dilution, excluding bridging to a single sample. Copper equivalent grades are calculated using a gold conversion factor of 0.63, determined using an updated copper price of USD3.00/pound and an updated gold price of USD1300/ounce. True widths of down hole intersections are estimated to be approximately 25-70%.
On the basis of the drilling results to date and the results of the Alpala Maiden Mineral Resource Estimate, the reference to the Cascabel Project as “World Class” (or “Tier 1”) is considered to be appropriate. Examples of global copper and gold discoveries since 2006 that are generally considered to be “World Class” are summarised in Table A.
