Extensive Lithocap Identified at Rio Amarillo with Significant Copper and Gold Results
BISHOPSGATE, LONDON / ACCESSWIRE / May 30, 2019 / The Board of SolGold (LSE & TSX code: SOLG) is pleased to provide an update from the Company's regional exploration activities from its 100% owned Rio Amarillo Project in northern Ecuador, held by wholly owned subsidiary Carnegie Ridge Resources.
Highlights:
|
Initial exploration on the Rio Amarillo Project has identified 5 prospects on concessions Rio Amarillo 1 & 2. |
||||
|
|
An extensive 2km by 2.4km lithocap has been identified in Rio Amarillo 2. The lithocap is characterised by advanced argillic alteration with crackle and hydrothermal breccias. Veins rich in realgar (Photo 3) were also identified providing further evidence of hydrothermal activity. Lithocaps commonly form over porphyry intrusions. Best rock chip results from in and around the lithocap include: |
|||
|
|
R01001075 0.33% Cu, 0.31 g/t Au, 32 ppm Mo |
|||
|
|
R01001089 0.21% Cu, 0.05 g/t Au, 45 ppm Mo |
|||
|
|
Three other prospects have been identified in Rio Amarillo 1 surrounding the lithocap; known as the Chilanes, Cuambo and Pasquel prospects. |
|||
|
|
The Cuambo and Pasquel prospects are distal to the lithocap with epithermal vein mineralisation identified. Best rock chip results include: |
|||
|
|
Cuambo Prospect |
|||
|
|
R01001018 11.3 g/t Au |

Introduction
Ecuador is located on the rich and under-explored section of the Andean Copper Belt, from which 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 72 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, applying the successful exploration blueprint developed by SolGold over the last 4 years.
Drilling is scheduled to commence on regional projects as soon as practical following completion of permitting processes.
Further Information
The Rio Amarillo project consists of 3 concessions; Rio Amarillo 1, 2 & 3. Currently, 5 prospects have been identified on concessions 1 & 2. The main geological feature of the Rio Amarillo project is the extensive lithocap extending 2km by 2.4km in area.
Whilst the lithocap has an extensive covering of volcanic ash, outcrops of crackle and hydrothermal breccia (Photo 1) have been located, including areas of silica clay and advanced argillic hydrothermal alteration. Bordering the altered lithocap are various outcrops of diorite and quartz-diorite containing mineralised B type veins (Photo 2). Best rock chip results include:
|
R01001075 0.33% Cu, 0.31 g/t Au, 32 ppm Mo |
|
R01001089 0.21% Cu, 0.05 g/t Au, 45 ppm Mo |
|
R01001068 0.14% Cu, 0.84 g/t Au, 4 ppm Mo |
|
R01001056 0.12% Cu, 0.45 g/t Au, 5 ppm Mo |
Cuambo and Pasquel prospects are distal to the lithocap with epithermal vein mineralisation identified. The epithermal veining at these prospects are possibly associated with a deeper porphyry system that is responsible for the advanced argillic alteration forming the lithocap. Best results include:
|
Cuambo Prospect |
|
|
|
R01001018 11.3 g/t Au |
|
|
R01001019 1.85 g/t Au
|
|
Pasquel Prospect |
|
|
|
R01001290 13.35 g/t Au |
|
|
R01001294 3.00 g/t Au |
|
|
R01001295 2.45 g/t Au |
At the Chilanes prospect, located proximal to the lithocap, B type veins have been mapped and sampled. An outcrop of stockwork B type veins (Photo 5) has been identified hosted in a dark micro diorite - quartz diorite with the matrix altered to magnetite and chlorite, with best rock chip results including:
|
R01000025 0.93 g/t Au, 0.18% Cu, 11.85ppm Mo |
|
R01000026 0.90 g/t Au, 0.01% Cu, 13.75 ppm Mo |
|
R01000029 0.51 g/t Au, 0.13% Cu, 10.35 ppm Mo |
The Puguran is located in Rio Amarillo 2. It represents a 250m long quartz diorite outcrop in Palomar creek (Photo 6) with B and D type veins identified. Alteration in this creek is interpreted as potassic overprinted by later phyllic alteration. Rock saw sampling returned:
|
140m @ 0.24% Cu |
|
|
|
Including 13m @ 0.65% Cu |
|
|
Including 12m @ 0.38% Cu |

CAUTIONARY NOTICE
News releases, presentations and public commentary made by SolGold plc (the "Company") and its Officers may contain certain statements and expressions of belief, expectation or opinion which are forward looking statements, and which relate, inter alia, to interpretations of exploration results to date and the Company's proposed strategy, plans and objectives or to the expectations or intentions of the Company's Directors. Such forward-looking and interpretative statements involve known and unknown risks, uncertainties and other important factors beyond the control of the Company that could cause the actual performance or achievements of the Company to be materially different from such interpretations and forward-looking statements.
Accordingly, the reader should not rely on any interpretations or forward-looking statements; and save as required by the exchange rules of the TSX and LSE or by applicable laws, the Company does not accept any obligation to disseminate any updates or revisions to such interpretations or forward-looking statements. The Company may reinterpret results to date as the status of its assets and projects changes with time expenditure, metals prices and other affecting circumstances.
This release may contain "forward‑looking information" within the meaning of applicable Canadian securities legislation. Forward‑looking information includes, but is not limited to, statements regarding the Company's plans for developing its properties. Generally, forward‑looking information can be identified by the use of forward-looking terminology such as "plans", "expects" or "does not expect", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates" or "does not anticipate", or "believes", or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved".
Forward‑looking information is subject to known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, performance or achievements of the Company to be materially different from those expressed or implied by such forward‑looking information, including but not limited to: transaction risks; general business, economic, competitive, political and social uncertainties; future prices of mineral prices; accidents, labour disputes and shortages and other risks of the mining industry. Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward‑looking information. The Company does not undertake to update any forward-looking information, except in accordance with applicable securities laws.
The Company and its officers do not endorse, or reject or otherwise comment on the conclusions, interpretations or views expressed in press articles or third-party analysis, and where possible aims to circulate all available material on its website.
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.

Notes:
|
Mr. Martin Pittuck, MSc, CEng, MIMMM, is responsible for this Mineral Resource estimate and is an "independent qualified person" as such term is defined in NI 43-101. |
|
The Mineral Resource is reported using a cut-off grade of 0.3% copper equivalent calculated using [copper grade (%)] + [gold grade (g/t) x 0.6] based on a copper price of US$2.8/lb and gold price of US$1,160/oz. |
|
The Mineral Resource is considered to have reasonable potential for eventual economic extraction by underground mass mining such as block caving. |
|
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. |
|
The statement uses the terminology, definitions and guidelines given in the CIM Standards on Mineral Resources and Mineral Reserves (May 2014). |
|
The MRE is reported on 100 percent basis. |
|
Values given in the table have been rounded, apparent calculation errors resulting from this are not considered to be material. |
|
The effective date for the Mineral Resource statement is 16 November 2018. |
