Promising New Copper Prospects Discovered at the Porvenir and Timbara Projects.

 

The Board of SolGold (AIM code: SOLG) is pleased to provide an update on exploration at its 100% owned Porvenir and Timbara Projects, in Southern Ecuador.  The prospect is held in the 100% owned subsidiary Green Rock Resources.

 

HIGHLIGHTS:

 

Ø Outcropping porphyry style copper mineralisation discovered at Porvenir and Timbara.

 

Ø Both projects are of Jurassic age similar to nearby Fruta del Norte, Mirador and Santa Barbara deposits.

 

Ø Results from rock chip samples collected at the Porvenir Project include:

·     1.58% Cu    in sample R03000587

·     4.27% Cu    in sample R03000588

·     1.30% Cu    in sample R03000592

 

Ø Results from rock chip samples collected during stream reconnaissance at the Timbara Project include:

·     2.44% Cu    in sample R03000216

·     1.59% Cu    in sample R03000232

·     1.64% Cu    in sample R03000221

·     1.23% Cu    in sample R03000203

·     1.00% Cu        in sample R03000205

 

Ø Rock chips at Porvenir Project were identified by following up highly anomalous Cu stream sediment geochemistry over a 6km x 5.5km area. 

 

Ø Prospecting at Timbara is at a very early phase with only 1 of 4 concessions prospected thus far.  Early rock chip results indicate copper mineralisation over a NE-SW corridor up to 4.5km long x 1.2km wide.

Introduction:

 

SolGold is continuing to pursue its strategy to become a tier 1 copper producing company through aggressive exploration of its extensive tenement portfolio in Ecuador.  SolGold now has multiple field teams operating, utilising a specialised method of rapid prospect recognition in each of its 4 regional subsidiary companies.  Led by highly experienced senior geologists, teams have successfully located copper occurrences in 6 projects indicative of large mineralised porphyry systems. 

 

As previously announced, SolGold's technical teams have recently discovered an extensive new corridor of porphyry copper mineralisation at its 100% owned La Hueca Project and now two exciting new mineralised prospects have been discovered at Green Rocks's Porvenir and Timbara Projects located along trend, southwest of the La Hueca Project.  

 

Both the Porvenir and Timbara Projects are located in southern Ecuador on the prolific Andean Copper belt which is renowned as the production base for nearly half of the world's copper, (Figure 1).  SolGold holds a 100% interest in these two Projects through its Ecuadorean subsidiary company, Green Rock Resources S.A.  Both projects are hosted in Ecuador's eastern Jurassic Belt, which contains the Fruta del Norte epithermal gold deposit (14 million ounces gold), the Mirador copper porphyry deposit (3 million tonnes copper) and the Santa Barbara gold-(copper) porphyry deposit (8 million ounces gold).

 

Exploration Activities & Results

 

Four Green Rock field teams have recently been conducting rapid first pass exploration on the Porvenir and Timbara Projects.  Exploration activities include stream sediment, panned heavy concentrate and rock chip sampling along with detailed mapping.  SolGold's method of rapid evaluation of project areas is again producing exciting early results, establishing new porphyry copper camps for follow-up exploration.

 

Porvenir Project

 

A stream sediment sampling program at the Porvenir Project delineated two geochemical anomalies within the larger 6km x 5.5km stream anomaly, the Derrumbo and Bartolo prospects (Figure 2).   Initial follow-up stream reconnaissance rock chip sampling returned very high copper results of up to 4.27% Cu from the outcrop samples on the Bartolo prospect and significant copper results of up to 0.8% Cu were returned from the Derrumbo prospect. 

 

Copper mineralisation in the porphyry outcrops is related to chalcopyrite content with associated chalcocite - covellite - magnetite (Figures 3, 4 & 5).  Three main hydrothermal alteration styles can be distinguished at the Porvenir:

·     Early-stage alteration defined by magnetite-rich and sulfide poor zones with abundant epidote veinlets and disseminations;

·     Chlorite -sericite alteration related to the main mineralised stage; and

·     Late-stage, strong quartz-sericite-pyrite alteration.

 

Future Work

 

The next phase of exploration at Porvenir will comprise auger soil geochemistry to delineate drill targets.  Additional specialist soil sampling teams are being readied to begin this work.  The new teams will allow current field teams to continue initial evaluation of SolGold's 77 granted regional tenements.  An aeromagnetic survey is planned over the Porvenir Project. 

 

The soil teams will collect samples for both multi-element geochemistry and ASD analysis.   Results of the soil programs will be used to design future drilling programs.

 

Timbara Project

 

Field teams have recently started first pass evaluation activities on one of four Timbara Project tenements (Figure 6).  During a targeted program of stream sediment and panned heavy concentrate collection, rock chip samples were collected of notable mineralised outcrops.  Whilst the results of the stream sediment samples are still awaited, assays from the initial rock samples have been returned.  Results are very encouraging for both porphyry and peripheral skarn style mineralisation distal to the porphyry host.

 

Outcrops of porphyry style copper mineralisation typically comprise vein and disseminated chalcopyrite, pyrite with traces of bornite.  Associated hydrothermal alteration is characteristically sericite and chlorite. Skarn style outcrops are generally highly fractured with quartz veins and epidote alteration present. Sulphides in these outcrops comprise chalcopyrite, occurring with magnetite, galena and pyrite (Figures 7, 8 & 9). 

 

Whilst detailed sampling and mapping is required, early results suggest a potential mineralised NE-SW trend of 4.5km with anomalous outcrops suggesting a system corridor, variably altered and mineralised, between 1.2km and 1.5km in width.  Results from the stream geochemical sampling will help establish the extent and trend of this newly discovered copper prospect in the Timbara 2 tenement.

 

Future Work

 

Field teams are currently focussed on first pass evaluation of the remaining three Timbara Project tenements.  Once the stream sediment and panned heavy concentrate programs have been completed and results are returned, field teams will transition to targeted systematic mapping and rock chip sampling of anomalous streams to gain a better understanding of the geological controls, hydrothermal alteration and style of Cu mineralisation at Timbara.  An aeromagnetic survey will also be carried out over the Timbara Project.

NOTES TO EDITORS

 

SolGold is a Brisbane, Australia based, dual LSE and TSX‐listed (SOLG on both exchanges) copper gold exploration and future development company with assets in Ecuador, Solomon Islands and Australia.  SolGold's primary objective is to discover and define world‐class copper‐gold deposits.  The Board and Management Team have substantial vested interests in the success of the Company as shareholders as well as strong track records in the areas of exploration, mine appraisal and development, investment, finance and law.  SolGold's experience is augmented by state of the art geophysical and modelling techniques and the guidance of porphyry copper and gold expert Dr Steve Garwin.

 

In October 2017, at the Mines and Money Americas Conference in Toronto, SolGold's Nicholas Mather won the award for the CEO of the Year - Latin America.  SolGold won the Exploration Award for Latin America, and Ecuador won the Country Award for Latin America.

 

The Company announced USD54m in capital raisings in September 2016 involving Maxit Capital LP, Newcrest International Ltd and DGR Global Ltd, and a USD41.2m raising in June of 2017 largely from Newcrest International with USD1.2m raised from Ecuadorean investors.  All of these raisings were undertaken at substantial premiums to previous raisings, and SolGold currently has circa USD60m in available cash to continue the exploration and development of its flagship Cascabel Project.

 

Mr Craig Jones joined the SolGold Board on 3 March 2017, nominated to the Board of SolGold by Newcrest Mining, now a 14.54% shareholder in SolGold.  Mr Jones is a Mechanical Engineer and is currently the Executive General Manager Wafi-Golpu (Newcrest-Harmony MMJV).  He has held various senior management and executive roles within the Newcrest Group, including General Manager Projects, General Manager Cadia Valley Operations, Executive General Manager Projects and Asset Management, Executive General Manager Australian and Indonesian Operations, Executive General Manager Australian Operations and Projects, and Executive General Manager Cadia and Morobe Mining Joint Venture.  Prior to joining Newcrest, Mr Jones worked for Rio Tinto.

 

Cascabel, SolGold's 85% owned "World Class" (Refer www.solgold.com.au/cautionary-notice/) flagship copper‐gold porphyry project, is located in northern Ecuador on the under‐explored northern section of the richly endowed Andean Copper Belt.  SolGold owns 85% of Exploraciones Novomining S.A. ("ENSA") and approximately 5% of TSX‐V‐listed Cornerstone Capital Resources ("Cornerstone"), which holds the remaining 15% of ENSA, the Ecuadorian registered company which holds 100% of the Cascabel concession.  Subject to the terms of existing agreements, Cornerstone is debt financed by SolGold for its share of costs to completion of a Feasibility Study ("Financing Option").

 

In terms of repayment, SolGold shall receive 90% of Cornerstone's share of earnings or dividends from ENSA or the Tenement to which Cornerstone would otherwise be entitled until such time as the amounts so received equal the aggregate amount of expenditures incurred by SolGold that, but for the Financing Option, would have been payable by Cornerstone, plus interest thereon from the dates such expenditures were incurred at a rate per annum equal to LIBOR plus 2 per cent until such time as SolGold is fully reimbursed.

 

The investments by Newcrest for 14.54% of SolGold endorses Ecuador as an exploration and mining destination, the management team at SolGold, the dimension, size and scale of the growing Alpala deposit, and the prospectivity of Cascabel and its multiple targets.  The gold endowment, location, infrastructure, logistics are important competitive advantages offered by the project.

 

To date SolGold has completed geological mapping, soil sampling, rock saw channel sampling, geochemical and spectral alteration mapping over 25km2, along with an additional 9km2 of Induced Polarisation and 14km2 Magnetotelluric "Orion" surveys over the Alpala cluster and Aguinaga targets.

 

SolGold has completed over 56,800m of drilling and expended over USD66M in Ecuador, which includes Cascabel exploration, regional exploration, corporate costs and investments into Cornerstone.  This has been accomplished with a workforce of up to 260 Ecuadorean workers and geoscientists, and 6 expatriate Australian geoscientists.  The results of 39 holes drilled (including re-drilled holes) and assayed to date have produced some of the greatest drill hole intercepts in porphyry copper-gold exploration history, as indicated by Hole 12 (CSD-16-012) returning 1560m grading 0.59% copper and 0.54 g/t gold including, 1044m grading 0.74% copper and 0.54 g/t gold.

 

The average grade of all metres drilled to date on the project currently stands at 0.31% copper and 0.26 g/t gold.  Intensive diamond drilling is planned for the next 12 months with 12 drill rigs expected to be operational by early 2018, targeting over 120,000m of drilling in 2018.

 

Cascabel is characterised by fifteen (15) identified targets, "World Class" drilling intersections over 1km in length at potentially economic grades, and high copper and gold grades in richer sections, as well as logistic advantages in location, elevation, water supply, proximity to roads, port and power services; and a progressive legislative approach to resource development in Ecuador.

 

To date, SolGold has drill tested 4 of the 15 targets, being Alpala Northwest, Alpala Central, Hematite Hill, and Alpala Southeast.  Currently drill testing of Alpala Northwest, Alpala Central and Alpala Southeast targets is underway, with drill testing of the other priority targets to be considered following the publication of the Company's maiden resource estimate for Alpala, and the finalisation of further IP surveying and modelling work currently underway.

 

The Alpala deposit is open in multiple directions and the mineralised corridor marked for drill testing of the greater Alpala cluster occurs over a 2.2km strike length from Trivinio in the northwest to Cristal in the southeast.  The mineralised corridor is known to be prospective over approximately 700m width.

 

High priority targets within the Alpala cluster, at Moran approximately 700m to the north, and at Aguinaga approximately 2.3km north east, are closely modelled by 3D MVI magnetic signatures that currently encompass over 10Bt of magnetic rock.  Based on a strong spatial and genetic relationship between copper sulphides and magnetite, this body of magnetic rock is considered to be highly prospective for significant copper and gold mineralisation, and requires drill testing.

 

SolGold is focussing on extending the dimensions of the Alpala deposit including Alpala Central, Alpala Northwest, Alpala West, Alpala East, Alpala South East, Trivinio, and Carmen, over the coming Quarter.  Following completion of a Maiden Resource Estimate and then drill testing the other key targets within the Cascabel concession at Aguinaga, Tandayama-America, Moran, Cristal, Parambas and Chinambicito.

 

The Company is currently planning further metallurgical testing and completion of an independent Pre-Feasibility Study at Cascabel.  SolGold is investigating both high tonnage open cut and underground block caving operations, as well as a high grade / low tonnage initial underground development towards the economic development of the copper gold deposit/s at Cascabel.

 

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 25-50%.

 

Following a comprehensive review of the geology and prospectivity of Ecuador, SolGold and its subsidiaries have several applications for additional exploration licences in Ecuador over a number of promising porphyry copper gold targets throughout the Country.

 

SolGold, through its 4 subsidiary companies, has 100% ownership of 77 granted concessions throughout Ecuador.  Each subsidiary company has technical teams, led by experienced senior geologists, on the ground prospecting granted tenements and collecting baseline data, whilst regional geophysics surveys are being planned.  Copper occurrences have been identified at 6 projects to date: La Hueca, Machos, Rio Armarillo, Sharug, Porvenir and Timbara.

 

In Queensland, Australia the Company is evaluating the future exploration plans for the Mt Perry, Rannes and Normanby projects, with drill testing of the Normanby project planned for the coming quarter.  Joint venture agreements are being investigated for a joint venture partner to commit funds and carry out exploration to earn an interest in the tenements.

 

SolGold retains interests in its original theatre of operations, Solomon Islands in the South West Pacific, where the 100% owned, but as yet undrilled, Kuma prospect on the island of Guadalcanal exhibits surface lithocap characteristics which are traditionally indicative of a large metal rich copper gold intrusive porphyry system.  SolGold intends in the future to apply intellectual property and experience developed in Ecuador to target additional "World Class" copper gold porphyries at Kuma and other targets in Ecuador and the Solomon Islands.

 

SolGold is based in Brisbane, Queensland, Australia.  The Company is listed on the LSE and TSX, with both exchanges using the ticker code: SOLG, and currently has on issue a total of 1,516,245,686 fully-paid ordinary shares, 31,795,884 share options exercisable at 28p; 9,795,884 share options exercisable at 14p and 46,762,000 share options exercisable at 60p.

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 on the basis of comparisons with other drilling intersections from "World Class" deposits tabulated in Table 1, some of which have become, or are becoming, producing mines and on the basis of available independent opinions which may be referenced to define the term "World Class" (or "Tier 1").

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 (1Singer and Menzie, 2010; 2Schodde, 2006; 3Schodde and Hronsky, 2006; 4Singer, 1995; 5Laznicka, 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 cautions that the Cascabel Project remains an early exploration stage project at this time. Despite the relatively high copper and gold grades over long intersections and broad areas, and widespread surface mineralization discovered at the Cascabel Project to date, much of which has still not yet been drill tested, the Company has yet to prepare an initial mineral resource estimate at the Cascabel Project and any development or mining potential for the project remains speculative. There is inherent uncertainty relating to any project at an exploration stage, prior to the determination of a mineral resource estimate, preliminary economic assessment, pre-feasibility study and/or feasibility study.  There is no certainty that future results will yield the results seen to date or that the project will continue to be considered to contain a "World Class" deposit. Accordingly, past exploration results may not be predictive of future exploration results.

From the drilling results at the growing Alpala Porphyry Copper Gold Deposit (only) within the Cascabel Project, the Company considers the deposit to have significant resource potential and the data gathered has provided the basis for the estimation of an exploration target over the area drilled to date. Initial 3D modelling and grade shell interpolants have outlined an approximate exploration target at Alpala that ranges from 729Mt at 1.06% copper equivalent, using a cut-off grade of 0.4% copper equivalent, to 969Mt at 0.92% copper equivalent, using a cut-off grade of 0.3% copper equivalent. These estimates equate to an endowment of between 7.7-8.9Mt of contained copper equivalent (Figure A).

Copper equivalent grades used are calculated using a gold conversion factor of 0.63, determined using a copper price of USD 3.00/pound and a gold price of USD 1300/ounce. Drill hole intercepts are calculated 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. True widths of down hole intersections are estimated to be approximately 25-50%.

The Company cautions that the potential quantity and grade ranges (exploration target) disclosed above for the Alpala Porphyry Copper Gold Deposit within the Cascabel Project is conceptual in nature, and there has been insufficient exploration to define a mineral resource, and the Company is uncertain if further exploration will result in the exploration target being delineated within a mineral resource estimate.

On this basis, 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 2.
