Underground Drilling confirms multiple gold zones at Barry – Intersects 157.6 g/t Au over 1.3 metres

Val-d’Or, QC – March 4, 2019: Bonterra Resources Inc. (TSX-V: BTR, OTCQX: BONXF, FSE: 9BR1) (“Bonterra” or the “Company”) is pleased to announce results from its recently completed underground drilling campaign at the Barry project, with new high-grade gold mineralization intersections in various zones.

Drilling highlights include:

  • 13.4 g/t Au over 3.2 metres in hole BR18-03
  • 8.2 g/t Au over 5.3 metres in hole BR18-05
  • 15.4 g/t Au over 2.3 metres in hole BR18-08
  • 157.6 g/t Au over 1.3 metres in hole BR18-12B
  • 15.5 g/t Au over 4.5 metres in hole BR19-25

These results are from Bonterra’s diamond drilling campaign undertaken on the Barry Deposit during Q4 2018 and Q1 2019. The program consisted of 25 sub-horizontal drill holes totaling 7,548 metres. This campaign was successful in confirming the multiple gold zones utilizing 20- to 30-metre drill spacings, mainly on Level 100 (see attached figure). Most of the drill holes intersected gold mineralization where it was anticipated based on our current models.

Greg Gibson, Interim CEO, states: “We are extremely pleased with our recent underground drilling campaign at Barry which has proven to be a large success, attesting to the robust continuity and grade of the deposit. This new drilling data on the Barry deposit will be included in the upcoming property-wide resource estimate.”

The definition drilling campaign validates the location and grade of the gold-bearing zones at Barry and will allow for the planning of a proposed bulk sample in the upcoming months. The company also intends to increase the size of the Barry deposit by drill-testing multiple mineralized shears and tensional veins that remain open at depth along strike and down-dip.

The gold mineralization at the Barry project is structurally controlled and is hosted in a sheared basalt containing quartz-carbonate-albite veins with pyrite. Bonterra has identified five main sub-vertical and sub-parallel shear zones and approximately ten secondary more shallow-dipping tension veins. These structures are open in all directions.

Quality Control and Reporting Protocols

The Company uses a rigorous QA-QC analytical program according to industry standards. The analytical results were done by pyroanalysis (A.A.) at the mine laboratory. Blanks, duplicates and certified reference standards are inserted into the sample stream to monitor laboratory performance.  The company’s QA-QC analytical verification program requires that a minimum of 10% of the samples be audited at an independent laboratory.  These audit assays were sent to ALS laboratory located in Val-d’Or, Quebec. The results of the audits are consistent with those obtained.

Forward-looking statements are subject to a variety of risks and uncertainties that could cause actual events or results to differ from those reflected in the forward-looking statements.   Exploration results that include geophysics, sampling, and drill results on wide spacings may not be indicative of the occurrence of a mineral deposit. Such results do not provide assurance that further work will establish sufficient grade, continuity, metallurgical characteristics and economic potential to be classed as a category of mineral resource.  A mineral resource that is classified as “inferred” or “indicated” has a great amount of uncertainty as to its existence and economic and legal feasibility. It cannot be assumed that any or part of an “indicated mineral resource” or “inferred mineral resource” will ever be upgraded to a higher category of resource.
