Bluestone Announces Additional Drill Results Including 14.1 m of 16.2 g/t Au and 10.0 m of 15.0 g/t Au (true width)

Vancouver, British Columbia--(Newsfile Corp. - May 15, 2018) - Bluestone Resources Inc. (TSXV: BSR) (OTCQB: BBSRF) ("Bluestone" or the "Company") is pleased to announce additional positive drill results from the surface and underground resource definition drill program underway, at its Cerro Blanco Gold project in Guatemala. The work is being undertaken as part of the Feasibility Study planned for completion by the end of 2018.

Drilling results continue to validate the historical high-grade vein intercepts drilled by previous operators and more recently by Bluestone (see Company Press Release dated April 17, 2018). Assay highlights in this release include 15.0 g/t Au and 32.5 g/t Ag over 10.0 meters including 32.0 g/t Au and 75.8 g/t Ag over 3.9 meters in hole UGCB18-82 that targeted multiple veins in the North Ramp area. Surface hole CB18-396 drilled numerous intercepts including 16.2 g/t Au and 20.6 g/t Ag over 14.1 meters from 167.1 meters, including 64.9 g/t Au and 76.9 g/t Ag over 2.0 meters representing deeper extensions of the sheeted vein swarms beneath the South Ramp.

Darren Klinck, President & CEO commented, "As we transition from resource drilling into the engineering phase of the Feasibility Study, the drilling results continue to solidify our understanding and confidence in the new geological model at Cerro Blanco and definition of individual vein wireframes. Importantly, the drilling continues to highlight broad zones of high-grade mineralization comprising multiple vein sets considered amenable for underground bulk mining methods in the PEA."

Three drill rigs stationed within the underground development are undertaking in-fill drilling within key areas in the north, central and south zones of the Cerro Blanco deposit. One drill rig continues to operate on surface targeting deeper and peripheral extensions to mineralization. Gold and silver mineralization at Cerro Blanco is associated with epithermal quartz-adularia veins and vein swarms that sit immediately below a silicified cap that form a low-lying hill.

Assay results from nine underground drill holes and two surface holes are presented in Table 1, totalling 1,829 meters. Drilling is designed primarily to provide additional information within key areas of the resource model and validate previous historical drilling. The underground results presented in this press release are additional fan holes drilled from Platforms 3, 4 and 10 which complement drill results announced previously. Drilling is ongoing with results from a further 13 underground and 7 surface holes pending. Over 10,000 meters of surface and underground drilling are anticipated to be completed which will be incorporated into the Feasibility Study expected to be finished by the end of the year.

Underground drilling is ongoing and additional results will be reported when received. Assay results from the drill program will be incorporated into the new resource estimate planned for Q3 2018.

Notes: Hole prefix UGCB18 denotes underground drillhole, CB18 denotes surface drillhole. Intervals in bold are cited in the text of the news release. A top-cut of 140 g/t Au as per PEA was applied with no effect on calculated intervals. Only intercepts averaging over 3 g/t Au when diluted to a minimum 3 m true width were included. A complete table with hole coordinates and azimuth/ dip information accompany the Figures attached to this release.

About Cerro Blanco

The Cerro Blanco project consists of 3.2 kilometers of underground development, including two underground declines from surface (North and South Ramps). Prior to the acquisition of Cerro Blanco by Bluestone in 2017, a total of 115,500 meters were drilled in 522 holes by previous operators.

Cerro Blanco is a classic hot springs-related, low sulphidation epithermal gold-silver deposit. Gold and silver bearing epithermal veins are hosted within a sequence of volcaniclastics and sedimentary rocks (Mita Group), composite veins of chalcedony, quartz, adularia and calcite. The bulk of the veins sit below a silicified cap approximately 100 meters thick comprising a sequence of plant-rich sandstones, conglomerates, phreatic breccias, and thin sinter horizons (Salinas Group). The current resource has a footprint of 800 meters x 400 meters between elevations of 300 meters and 500 meters above sea level. It occurs at the south end of a north-south corridor of hydrothermal alteration, about five kilometers long and one kilometer wide, which has potential for discovery of additional mineralization. This corridor has several other gold targets currently under investigation. The current resource comprises both high- and low-angle veins of colloform-banded chalcedony with minor adularia, dark grey bands of silver sulphides and bladed calcite replacement textures. These textures are all classic indicators of boiling fluids that deposited gold and silver.

Quality Analysis and Quality Control

Assay results listed within this release were performed by Inspectorate Laboratories ("Inspectorate"), a division of Bureau Veritas, which are ISO 17025 accredited laboratories. Logging and sampling is undertaken at site at Cerro Blanco by Company personnel under a QA/QC protocol developed by Bluestone. Samples are transported in security-sealed bags to Inspectorate, Guatemala City, Guatemala, for sample preparation. Sample pulps are shipped to Inspectorate Laboratories in Vancouver, BC, Canada or Reno, NV, USA, and assayed using industry-standard assay techniques for gold and silver. Gold and silver were analyzed by a 30-gram charge with atomic adsorption and/or gravimetric finish for values exceeding 5 g/t Au and 100 g/t Ag. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material, and replicate samples. Quality control is further assured by Bluestone's QA/QC program, which involves the insertion of blind certified reference materials (standards) and field duplicates into the sample stream to independently assess analytical precision, and accuracy of each batch of samples as they are received from the laboratory. A selection of samples is submitted to ALS Chemex Laboratories in Vancouver for check analysis and additional quality control.

Cautionary Language

The PEA is preliminary in nature, it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
