Bonterra drills 1.6 m of 15.6 g/t Au at Gladiator

The Barbeau Zone consists of quartz vein mineralization hosted by a shear zone dipping moderately to the north and correlates with an offset of the gabbroic and felsic dykes. Several secondary mineralized zones called "North Dippers" have been interpreted with orientations similar to the Barbeau Zone, moderately to steeply dipping north. A series of mineralized zones associated with felsic dykes are referred to as North Corridor, Footwall and South Zones and are interpreted to occur with similar orientations to the North and Main Zones dipping south-southeast (Figures 1 and 4).

Pascal Hamelin, Interim CEO and VP, Operations commented: "These latest drill results are very encouraging, and demonstrate the continuity of the Main and North Zones. The addition of a series of interpreted north-dipping zones to the Main and North Zones further enhances our understanding of the Gladiator deposit."

The following table shows the significant intersections of the drill holes presented in this press release.

Notes:

1) The meterage represents the length of the drilled lengths.

2) Estimated true widths for the interpreted Main, North, South and Footwall Zones range from at least 50% to 90% of the interval core length. The estimated true widths of the North Dipper, Barbeau and North Corridor Zones are unknown.

3) The mineralized intervals listed are above 0.5 g/t Au.

Ten holes intersected the Main Zone and filled the gap in the drilling pattern (BA-20-04; 06; 10; 11; 12; 14; 16; 17; 18A; 20). Highlights include 15.6 g/t Au over 1.6 m in hole BA-20-20, 2.7 g/t Au over 10.2 m, including 13.7 over 0.7 m in hole BA-20-11 and 10.5 g/t Au over 1.1 m in hole BA-20-04 (Figure 2).

Seven holes (BA-20-08; 09; 13; 14; 17;18A; 20) were drilled to target the North Zone extension following very encouraging results from holes BA-20-05 and BA-20-07 drilled during the winter (See press releases April 2, 2020 and April 24, 2020). Best results included 2.9 g/t Au over 6.6 m, including 10.2 g/t Au over 1.8 m and 2.9 g/t Au over 5.5m, including 11.6 g/t Au over 1.0 m in hole BA-20-13.

Several newly modelled north dipping zones ("North Dippers") were intersected by the ongoing drilling program, of which the best intervals returned: 12.7 g/t Au over 1.0 m in BA-20-12, 40.5 g/t Au over 0.5 m in hole BA-20-17, 30.3 g/t Au over 0.7 m in hole BA-20-18A and 8.0 g/t Au over 1.3 m, including 19.0 g/t Au over 0.5 m in hole BA-20-19 (Figure 4).

Quality control and reporting protocols

The Gladiator project's drill core gold analysis is performed at the Bachelor Mine Analysis Laboratory. The Company employs a rigorous QA-QC analysis program that meets industry standards. The analytical results are carried out by fire assay (A.A.) in 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 at least 10% of samples be audited in an independent laboratory. These verification sample were sent to the ALS laboratory located in Val-d'Or, Quebec. The results of the audits are consistent with those obtained.

Cautionary and Forward-Looking Statements

This press release contains "forward-looking information" that is based on Bonterra's current expectations, estimates, forecasts and projections. This forward-looking information includes, among other things, statements with respect to Bonterra's exploration and development plans. The words "will", "anticipated", "plans" or other similar words and phrases are intended to identify forward-looking information. This forward-looking information includes namely, information with respect to the planned exploration programs and the potential growth in mineral resources. Exploration results that include drill results on wide spacings may not be indicative of the occurrence of a mineral deposit and 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. The potential quantities and grades of drilling targets are conceptual in nature and, there has been insufficient exploration to define a mineral resource, and it is uncertain if further exploration will result in the targets being delineated as mineral resources. Forward-looking information is subject to known and unknown risks, uncertainties and other factors that may cause Bonterra's actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking information. Such factors include but are not limited to: uncertainties related exploration and development; the ability to raise sufficient capital to fund exploration and development; changes in economic conditions or financial markets, environmental and other judicial, regulatory, political and competitive developments; technological or operational difficulties or inability to obtain permits encountered in connection with exploration activities; and labour relations matters. This list is not exhaustive of the factors that may affect our forward-looking information. These and other factors should be considered carefully and readers should not place undue reliance on such forward-looking information.
