Bluestone Drills 21.4 m grading 9.6 g/t Au and 34.9 g/t Ag at Cerro Blanco
July 5, 2018 – VANCOUVER, BRITISH COLUMBIA – Bluestone Resources Inc. (TSXV:BSR | OTCQB:BBSRF) ("Bluestone" or the "Company") is pleased to announce further positive drill results from its resource definition drill program at the Cerro Blanco Gold project in Guatemala.
Highlights include the following intercepts representing true widths of the veins:
- 9.6 g/t Au and 34.9 g/t Ag over 21.4 m (UGCB18-92)
- 11.5 g/t Au and 48.6 g/t Ag over 12.9 m (UGCB18-96)
- 16.5 g/t Au and 18.4 g/t Ag over 7.9 m (CB18-393)
- 7.0 g/t Au and 65.2 g/t Ag over 17.2 m (CB18-394) including
17.5 g/t Au and 197 g/t Ag over 4.1 m
Results in this press release include seven holes drilled from within the 3.2 km of underground mine workings and six holes drilled from surface.
Holes UGCB18-92 and UGCB18-96 are infill holes drilled in the South Ramp underground workings from the same platform as holes UGCB18-86 and UGCB18-89 previously reported (see Company press release May 30, 2018). These latest holes continue to re-affirm the new geological model developed by Bluestone, where broad widths of high-grade mineralization occur due to multiple quartz-adularia veins converging at depth, possibly representing a feeder structure. Visible gold can be observed associated with zones of dark grey quartz and acanthite (a silver sulphide mineral) within these high-grade vein intercepts.
Importantly, UGCB18-98, drilled in the southeast into the hanging wall of the veins, encountered a series of new high-grade veins that were discovered by Bluestone’s recent underground channel sampling program in the South Ramp access tunnel. These veins were previously unknown and will be included in the updated resource estimate being undertaken as part of the current Feasibility Study expected in Q4 2018.
Darren Klinck, President & CEO commented, " We continue to be very pleased with the results from the feasibility drilling program earlier this year. As a result, we have enhanced our confidence in the continuity of the high-grade veins and the geologic model has now been transferred to the mine design team as part of the mine planning activities for the Feasibility Study." He added, " Our understanding of the geologic potential within and immediately adjacent to the current deposit, has been significantly enhanced through the drilling and sampling programs. The focus of our geology team on exploration will certainly be key as we move ahead with our objective to expand the resources at Cerro Blanco over the coming quarters."

Additional assays continue to be received that show long intervals of low grade mineralization in surface holes collared in a tabular, silicified sedimentary unit that is roughly 100-120 m thick that overlies and conceals the majority of the high-grade veins at Cerro Blanco. This unit is host to disseminated gold showing potential for bulk tonnage mineralization, e.g., CB-388 drilled 108.9 m grading 1.03 g/t Au and 1.91 g/t Ag from 21.7 m to 130.5 m below surface. Assays are still being received and will be compiled and assessed when complete. Host rocks comprise a sequence of sandstones, conglomerates, phreatic breccias and thin sinter horizons (Salinas Group) that have been subject to widespread silicification and argillic alteration, characteristic of a silica cap preserved above hot springs precious metal deposits.

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 are undertaken on 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 absorption 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.
David Cass, P.Geo., Vice President Exploration, is the designated Qualified Person for this news release within the meaning of National Instrument 43-101 and has reviewed and verified that the technical information set out above in this news release is accurate and therefore approves this written disclosure of the technical information.

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.
