ALPALA MINERAL RESOURCE ESTIMATE DOUBLES SINCE DEC 2017
Solgold PLC has provided an update on the mineral resource
estimate at the company's Alpala porphyry copper-gold deposit in northern Ecuador.
- Alpala updated mineral resource estimate (MRE) totals a current:
2,050 million tonnes at 0.60 per cent copper equivalent (CuEq) (at 0.2-per-cent CuEq cut-off) in the indicated category, and 900 million tonnes at 0.35 per cent
CuEq (at 0.2-per-cent CuEq cut-off) in the inferred category;
- Contained metal content of 8.4 Mt Cu and 19.4 Moz Au in the indicated category;
Contained metal content of 2.5 Mt Cu and 3.8 Moz Au in the inferred category.
Alpala updated MRE across both indicated and inferred classifications equates to a current 2.95 billion tonnes
at 0.52 per cent CuEq (15.4 Mt CuEq) containing 10.9 Mt Cu and 23.2 Moz Au at 0.2-per-cent CuEq cut-off, 79 per cent of
which is in the indicated category (by metal content);
- 420 Mt high-grade core at 1.47 per cent CuEq (6.1 Mt CuEq) containing 3.8 Mt Cu and 12.3 Moz Au at 0.9-per-cent
CuEq cut-off, 97 per cent of which is in the indicated category (by metal content);
MRE reported using a cut-off grade of 0.2 per cent CuEq, reflecting the reasonable potential for economic
extraction by high production rate mass mining methods such as block caving;
Increase in overall reported resource of 108 per cent (by metal content) from 7.4 Mt CuEq in December, 2017,
maiden MRE (0.3-per-cent CuEq cut-off) to current 15.4 Mt CuEq (0.2-per-cent CuEq cut-off);
Increase in resource of 77 per cent (by metal content) from 7.4 Mt CuEq to 13.1 Mt CuEq since December, 2017,
maiden MRE (1.08 Bt at 0.68 per cent CuEq, 7.4 Mt CuEq at 0.3-per-cent cut-off grade, 40 per cent indicated);
- Increase in high-grade resource size of 99 per cent (by metal content) from 3.1 Mt CuEq to 6.1 Mt CuEq
since December, 2017, maiden MRE (220 Mt at 1.44 per cent CuEq, 3.1 Mt CuEq at 0.9-per-cent cut-off grade, 55 per cent
Potential for further growth with the 2019 drilling campaign to continue to expand the deposit at
Alpala SE, Alpala NW, Trivinio and Alpala Western Limb.
Commenting on today's release, Solgold CEO, Mr Nick Mather said:
"We are very happy with the rapid and inexorable growth of this resource and progression of the Alpala
project. The high-grade, gold-rich core of the deposit now contains double the copper and gold at a
higher grade than in December, 2017. The high-grade resource has increased in size by 99 per cent at a 0.96-per-cent
CuEq cut-off to 420 Mt at 1.47 per cent CuEq. Over all, the resource metal content has increased by 77 per cent at a 0.3-per-cent copper equivalent cut-off and by 108 per cent at a 0.2-per-cent copper equivalent cut-off.
"The project has approximately 950 Mt at 0.97 per cent CuEq for 6.1 Mt copper and 16.2 Moz gold, significantly
exceeding the generally held requirement of 750 Mt at at a grade of at least 0.9 per cent copper equivalent for
Tier 1 status for both copper and gold projects worldwide. Alpala has got more to grow yet and we are
pursuing that aggressively over the coming months.
"The preliminary economic analysis (PEA) is advancing and feasibility studies will follow seamlessly. Our
aim is to fast-track towards development.
"Solgold's project is Ecuador. We have secured 100-per-cent interest in 11 other high-priority copper gold targets
throughout the 750-kilometre length of Ecuador and our aim is to define a pipeline of Tier 1 and world-class copper gold projects along a 750 km stretch of the most neglected sector of the Andean copper
belt, the world's most prolific copper province. We aim to drill test these as soon as possible. The skills
we've developed at Alpala will make the next generation of Solgold's discoveries even faster and more
"Solgold holds the most extensive and best selected position over 72 licences, covering 11 major targets,
as a result if our first mover advantage four years ago in Ecuador. Ecuador covers the same extent, age
and gross geology as you see in northern Chile, which covers 25 per cent of the world's copper resources.
"Alpala is just the beginning for Solgold and we can see the emergence of the company as a copper gold
major and Ecuador becoming one of the world's largest copper producers as a result.
"Global electrification is driving copper demand and 'copper is the new iron ore.' It's a global must
"I take this opportunity to thank our staff, all 450 of them, 97 per cent Ecuadorean, the local communities and
our award-winning management team for delivery of this resource upgrade; and offer the boards
thanks to shareholders and investors, most recently BHP, for the support required to date."
The Alpala deposit is located in northern Ecuador, lying upon the northern section of the prolific Andean
copper belt, renowned as the base for nearly half of the world's copper production. The project area
hosts mineralization 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 is a three-hour drive north of Quito, close to water, power
supply and Pacific ports. Solgold holds an 85-per-cent registered and beneficial interest in ENSA
(Exploraciones Novomining SA) which holds 100 per cent of the Cascabel tenement.
November, 2018, Alpala mineral resource estimate
The November, 2018, Alpala MRE update, dated Nov. 15, 2018, was estimated from 68,173 assays, with 66,739
assays representing diamond drill core samples, and 1,434 assays representing rock-saw channel samples
cut from surface rock exposures. Drill core samples were obtained from total of 133,576 metres of drilling
comprising 128 diamond drill holes, including 75 drill holes (holes 1 to 75), 34 daughter holes, eight redrills and
11 overruns, and represents full assay data from holes 1 to 67 and partial assay data received from holes
68 to 75. Rock-saw samples were obtained from 2,743 m of rock-saw cuts from 262 surface rock exposure
trenches. In contrast, the December, 2017, maiden MRE was estimated from 26,814 assays obtained from
53,616 m of drilling comprising 45 drill holes (holes 1 to 33) including 10 daughter holes and five redrills.
There now exists approximately triple the amount of drilling and assay information since the maiden MRE
of December, 2017, and this has resulted in significant growth in tonnage (approximately 273 per cent) and
contained metal (approximately 108 per cent) and a far greater proportion of the MRE now being in the indicated
mineral resource category (2018: 77 per cent, 2017: 40 per cent).
The November, 2018, Alpala updated mineral resource estimate (MRE) totals a current:
2,050 Mt at 0.60 per cent CuEq (at 0.2-per-cent CuEq cut-off) in the indicated category, and 900 Mt at 0.35 per cent CuEq (at 0.2-per-cent CuEq cut-off) in the inferred category;
- Contained metal content of 8.4 Mt Cu and 19.4 Moz Au in the indicated category;
- Contained metal content of 2.5 Mt Cu and 3.8 Moz Au in the inferred category.
Alpala updated MRE across both indicated and inferred classifications equates to a current 2.95 Bt at 0.52 per cent CuEq (15.4 Mt CuEq) containing 10.9 Mt Cu and 23.2 Moz Au at 0.2-per-cent CuEq cut-off, 79 per cent of which is
in the indicated category (by metal content) (see attached tables).
The Alpala deposit includes a 420 Mt high-grade core at 1.47 per cent CuEq (6.1 Mt CuEq) containing 3.8 Mt Cu
and 12.3 Moz Au at a 0.9-per-cent CuEq cut-off, 97 per cent of which is in the indicated category (by metal content).
The November, 2018, MRE update is reported using a cut-off grade of 0.2 per cent copper equivalent (CuEq) which
Solgold and SRK Consulting consider to be reasonable, reflecting the potential for economic extraction by
high production rate mass mining methods such as block caving. The central portions of the deposit
present an opportunity for early extraction of higher grade material.
The updated MRE is presented on a 100-per-cent basis and has an effective date of Nov. 7, 2018. It
represents an overall reported resource increase of 108 per cent (by metal content) from 7.4 Mt CuEq in December, 2017,
maiden MRE (at a cut-off of 0.3 per cent CuEq) to the current 15.4 Mt CuEq (at a cut-off of 0.2 per cent CuEq).
