Highlights:
VANCOUVER, May 17, 2016 /CNW/ - Brazil Resources Inc. (the "Company" or "Brazil Resources") (TSX-V: BRI; OTCQX: BRIZF) is pleased to announce the results of a National Instrument 43-101 ("NI 43-101") mineral resource estimate for the Raintree West deposit, one of several porphyry centers identified on the Whistler Project, Alaska. The 100%-owned district-scale Whistler Project (170 sq km) is located 150 kilometres northwest of Anchorage, Alaska.
Garnet Dawson, CEO, stated: "We are pleased to report this maiden NI 43-101 resource estimate for the Raintree West deposit, which builds on the multi-million ounce gold resource reported over the last year on the Whistler Project. This estimate increases BRI's indicated resource to 3.2 Moz gold (4.2 Moz gold equivalent) and our inferred resource to 7.0 Moz gold (9.1 Moz gold equivalent; Table 4). In conjunction with advancing our existing project portfolio, the Company continues to evaluate resource-stage projects in the Americas for potential acquisition."
Raintree West Resource Estimate
Brazil Resources engaged Giroux Consulting Ltd. to prepare an independent NI 43-101 technical report for the Whistler Project, including the first-time resource estimate on the Raintree West deposit. The resource estimates for the inferred resource at various cut-off grades are shown in Tables 1 and 2, respectively. The technical report documenting the procedures and results of this estimate will be filed on SEDAR in due time.

Table 3 Notes:
The Raintree West deposit is one of several porphyry centers identified on the Whistler Project (Fig. 1). The deposit is located 1500 metres east of the Whistler deposit and has been drilled over a strike length of 500 metres and to a depth of 700 metres; the deposit is up to 400 metres in width. The deposit is open along strike to the north and south, and at depth. Gold-copper mineralization is associated with quartz + magnetite stockwork zones hosted in potassic altered diorite intrusive rocks.
The Raintree West deposit was modelled on a series of east-west cross-sections and a grade shell (0.1 g/t AuEq) representing the mineralization was constructed to constrain the resource estimate. Fourteen diamond drill holes totaling 7,078 metres were used to define the model. Erratic high grade outliers for gold, silver and copper were capped within the mineralized and waste solids. Composites 5 metres in length were formed within each of the domains that honoured the domain boundaries. Variography was used to model the grade continuity and to determine the search ellipse orientations and dimensions for interpolation. Ordinary kriging was used to estimate gold, silver and copper into blocks measuring 10 x 10 x 10 metres in dimension. A total of 39 samples within the mineralized solid had specific gravity measurements, which were used to convert volumes to tonnes. The blocks were classified as Inferred based on the limited amount of drilling. For the near surface mineralization above 250 m elevation (Zone B), a 0.30 g/t gold equivalent cut-off grade was chosen as a possible open pit cut-off based on studies completed at the nearby Whistler deposit. For the deeper mineralization below 100 m elevation (Zone A), a 0.60 g/t gold equivalent cut-off grade was chosen as a possible block cave cut-off based on the New Afton mine in British Columbia that is currently in production and using a similar mining method. Validation of the model was completed by comparison of the block model and drill hole grades by visual inspections in section and plan across the deposit. There are no known legal, political, environmental or other risks that could materially affect the potential development of the mineral resources.
An updated technical report on the Whistler Project including the new resource estimates on the Raintree West and Island Mountain deposit will be filed on SEDAR in due course.
Quality Control – Quality Assurance Program
The above resource estimate was based on drill programs completed by previous operators that incorporated control samples including blanks, duplicates and standards as part of their Quality Control – Quality Assurance Program. The control samples from these programs have been reviewed and verified by the Qualified Persons and the assay results were deemed suitable for resource estimation.
Qualified Person Statement
The resource estimate disclosed herein was prepared for Brazil Resources by Gary Giroux, MASc., P.Eng. of Giroux Consultants Ltd, who is a Qualified Persons as defined in NI 43-101, is independent of the Company and has reviewed and approved the disclosure regarding the Raintree West resource estimate.
A technical report respecting the above resource estimate will be filed under the Company's profile on SEDAR in due course. There is no new material scientific or technical information respecting the Whistler Project since the effective date of the resource estimate.
Paulo Pereira, Brazil Resources' President, has reviewed and approved the technical information contained in this news release. Mr. Pereira holds a bachelors degree in Geology from Universidade do Amazonas in Brazil, is a Qualified Person as defined in NI 43-101 and is a member of the Association of Professional Geoscientists of Ontario.

Cautionary Note
Investors are cautioned not to assume that any part or all of the mineral deposits in the "indicated" and "Inferred" categories will ever be converted into mineral reserves with demonstrated economic viability or that inferred mineral resources will be converted to the measured and/or indicated categories through further drilling. In addition, the estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or other economic studies.
Forward Looking Statements
This document contains certain forward-looking statements that reflect the current views and/or expectations of Brazil Resources with respect to its business and future events, including statements regarding the estimation of mineral reserves and the Company's expectations respecting the Whistler Project. Forward-looking statements are based on the then-current expectations, beliefs, assumptions, estimates and forecasts about the business and the markets in which Brazil Resources operates. Investors are cautioned that all forward-looking statements involve risks and uncertainties, including: the inherent risks involved in the exploration and development of mineral properties, the uncertainties involved in interpreting drill results and other exploration data, the potential for delays in exploration or development activities, the geology, grade and continuity of mineral deposits, the possibility that future exploration, development or mining results will not be consistent with Brazil Resources' expectations, accidents, equipment breakdowns, title and permitting matters, labour disputes or other unanticipated difficulties with or interruptions in operations, fluctuating metal prices, unanticipated costs and expenses, uncertainties relating to the availability and costs of financing needed in the future, commodity price fluctuations, regulatory restrictions, including environmental regulatory restrictions, or any failure to integrate acquired companies and projects into the Company's existing business as planned. These risks, as well as others, including those set forth in Brazil Resources' filings with Canadian securities regulators, could cause actual results and events to vary significantly. Accordingly, readers should not place undue reliance on forward-looking statements and information. There can be no assurance that forward-looking information, or the material factors or assumptions used to develop such forward looking information, will prove to be accurate. Brazil Resources does not undertake any obligations to release publicly any revisions for updating any voluntary forward-looking statements, except as required by applicable securities law.
