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."

GLOSSARY OF TERMS
The 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.
