Serabi Gold plc("Serabi" or the
"Company")
Updated Mineral Resource and Mineral Reserve
Statement
Serabi Gold (AIM:SRB, TSX:SBI), the Brazilian
focused gold mining and development company, is pleased to announce
updated Mineral Resource and Mineral Reserve estimates for its
Tapajos mining and processing operations ("Tapajos Operations"),
prepared in accordance with the standard of CIM and Canadian
National Instrument 43-101 with an effective date of 30 June 2017,
as outlined below. The Tapajos Operations currently comprise
the mining and processing of the Palito and Sao Chico
ore-bodies.Highlights
- A combined estimated Proven and Probable mineral reserve for
the Palito and Sao Chico ore-bodies of 182,000 ounces of contained
gold (703,000 tonnes at an average diluted grade of 8.05 g/t)
supporting in excess of four years of production.
- Mineral reserves for the Palito ore-body are estimated at
157,000 ounces of contained gold (613,000 tonnes at an average
diluted gold grade of 7.99 g/t).
- Mineral reserves for the Sao Chico ore-body are estimated at
24,000 ounces of contained gold (90,000 tonnes at an average
diluted gold grade of 8.43 g/t).
- Measured and Indicated mineral resources for the Palito
ore-body increased by 31 per cent., compared with the previous
resource estimation of June 2012, to 271,000 ounces of contained
gold with a further Inferred mineral resource of 177,000 ounces of
contained gold.
- Measured and Indicated mineral resources for Sao Chico ore-body
increased by 44 per cent., compared with the October 2012 resource
estimation, to 36,000 ounces of contained gold with an additional
Inferred mineral resource of 54,000 ounces of contained
gold.
- The mineral resource and reserve estimates exclude previously
announced gold discoveries made by Serabi including the Currutela,
Copper Hill, Piaui and Palito South areas, where there is currently
insufficient geological data to estimate a mineral resource for
these discoveries.
- An infill drill programme is currently underway that will
provide additional geological date on each of these project
areas.
(Note: All reserve and resource figures stated above are
both gross and net attributable to Serabi.)
Mike Hodgson, CEO of Serabi, commented:
"From the time that production re-commenced at the Palito Mine
in late 2013 until the end of June 2017, we estimate that
approximately 118,000 contained gold ounces have been mined from
the Palito ore-body (385,700 tonnes at an average mined gold grade
of 9.52 g/t). That we are now able to declare a Measured and
Indicated mineral resource with an estimated 271,000 contained gold
ounces as of 30 June 2017 is encouraging and demonstrates that our
efforts to delineate new mineral resources with in-fill and
step-out drilling programmes has been successful at Palito.
This represents an increase of 31 per cent in the Measured and
Indicated mineral resources compared with the last estimation of
June 2012, which was undertaken prior to the re-commencement of
production.
"We are also encouraged by the fact that we have been able to
convert a significant amount (58 per cent of the contained gold) of
our Measured and Indicated mineral resources into Proven and
Probable mineral reserves, which total 157,000 contained gold
ounces as of 30 June 2017 (613,000 tonnes at an average diluted
gold grade of 7.99 g/t).
"Similarly, at the Sao Chico Mine we have mined approximately
28,000 contained gold ounces since commercial production was
declared in January 2016 (89,500 tonnes at an average mined gold
grade of 9.74 g/t). Again as a result of successful in-fill
and step-out drilling programmes, we are pleased to report that as
of 30 June 2017, the Measured and Indicated resources at Sao Chico
have grown to 36,000 contained gold ounces (82,000 tonnes at an
average in situ gold grade of 13.70 g/t) representing a 44 per cent
improvement compared with the previous resource estimation. A
significant portion of these Measured and Indicated resources (67
per cent of the contained gold) have also been converted into
mineral reserves, and we are also pleased to report Proven and
Probable mineral reserves totalling 24,000 contained gold ounces
(90,000 tonnes at an average diluted gold grade of 8.34 g/t).
"It is a great comfort to have significant mineral
resources and mineral reserves defined at both Palito and Sao
Chico, and it is a very healthy position for an underground, vein
mining operation to have over four years of mineral reserves
defined. This is a reflection of the investment that the
Company has made in ensuring that exploration and development is
completed well in advance of production, thereby generating the
levels of geological data required to define new mineral resources
and mineral reserves.
"This should provide comfort to stakeholders in the
ability of the Company to maintain its current levels of
production. We remain focussed on ensuring costs are closely
controlled and on realising the potential for further improvements
in operational efficiencies over the coming quarters."

This announcement is inside information for the purposes of
Article 7 of Regulation 596/2014.
GLOSSARY OF TERMSThe following is a
glossary of technical terms:
Note: Mineral resources and reserves were
estimated in conformity with the widely accepted CIM Estimation of
Mineral Resource and Mineral Reserves Best Practices Guidelines
(the "Guidelines") and are reported in accordance with the Canadian
Securities Administrators' National Instrument 43-101" and the
definitions applicable to individual categories of reserves and
resources are set out in the Guidelines. The Glossary below
includes only a summary of these definitions and readers can access
the full definitions at
http://web.cim.org/standards/menupage.cfm?sections=177&menu=178
"Au" means gold.
"CIM" means Canadian Institute of Mining,
Metallurgy and Petroleum.
"development" - excavations used to establish
access to the mineralised rock and other workings.
"grade" is the concentration of mineral within
the host rock typically quoted as grams per tonne (g/t), parts per
million (ppm) or parts per billion (ppb).
"g/t" means grams per tonne.
"Indicated Mineral Resource" is that part of a
Mineral Resource for which quantity, grade or quality, densities,
shape and physical characteristics can be estimated with a level of
confidence sufficient to allow the appropriate application of
technical and economic parameters, to support mine planning and
evaluation of the economic viability of the deposit. The estimate
is based on detailed and reliable exploration and testing
information gathered through appropriate techniques from locations
such as outcrops, trenches, pits, workings and drill holes that are
spaced closely enough for geological and grade continuity to be
reasonably assumed.
"Inferred Mineral Resource" is that part of a
Mineral Resource for which quantity and grade or quality can be
estimated on the basis of geological evidence and limited sampling
and reasonably assumed, but not verified, geological and grade
continuity. The estimate is based on limited information and
sampling gathered through appropriate techniques from locations
such as outcrops, trenches, pits, workings and drill holes.
"Measured Mineral Resource" is that part of a
Mineral Resource for which quantity, grade or quality, densities,
shape, and physical characteristics are so well established that
they can be estimated with confidence sufficient to allow the
appropriate application of technical and economic parameters, to
support production planning and evaluation of the economic
viability of the deposit. The estimate is based on detailed and
reliable exploration, sampling and testing information gathered
through appropriate techniques from locations such as outcrops,
trenches, pits, workings and drill holes that are spaced closely
enough to confirm both geological and grade continuity.
"Mineral Resource" is a concentration or
occurrence of diamonds, natural solid inorganic material, or
natural solid fossilized organic material including base and
precious metals, coal, and industrial minerals in or on the Earth's
crust in such form and quantity and of such a grade or quality that
it has reasonable prospects for economic extraction. The location,
quantity, grade, geological characteristics and continuity of a
Mineral Resource are known, estimated or interpreted from specific
geological evidence and knowledge.
"Mineral Reserve" is the economically mineable
part of a Measured or Indicated Mineral Resource demonstrated by at
least a Preliminary Feasibility Study. This Study must include
adequate information on mining, processing, metallurgical, economic
and other relevant factors that demonstrate, at the time of
reporting, that economic extraction can be justified. A Mineral
Reserve includes diluting materials and allowances for losses that
may occur when the material is mined.
"Probable Mineral Reserve" is the economically
mineable part of an Indicated and, in some circumstances, a
Measured Mineral Resource demonstrated by at least a Preliminary
Feasibility Study. This Study must include adequate information on
mining, processing, metallurgical, economic, and other relevant
factors that demonstrate, at the time of reporting, that economic
extraction can be justified.
"Proven Mineral Reserve" is the economically
mineable part of a Measured Mineral Resource. A Proven Mineral
Reserve implies a high degree of confidence in the Modifying
Factors.
"t" means tonnes
"Vein" is a generic term to describe an
occurrence of mineralised rock within an area of non-mineralised
rock.
