ROXGOLD EXTENDS QV1 MINERALIZATION AT BAGASSI SOUTH AND ANNOUNCES ADDITIONAL RESULTS FROM ITS DEVELOPMENT INFILL DRILLING ON THE 55 ZONE; INFILL DEVELOPMENT DRILLING CONTINUES TO CONFIRM CONTINUITY OF HIGH GRADE ON THE 55 ZONE WHILE STEP OUT DRILLING AT BAGASSI SOUTH CONTINUES TO GROW STRIKE LENGTH OF QV1

Roxgold Inc. has released the latest results from development infill drilling program at the 55 zone, as well as further results from its Bagassi South regional exploration target.

55 zone infill drilling highlights:

• 200.7 grams per tonne gold over 5.9 metres (4.8 metres estimated true width), including 460.0 grams per tonne gold over 2.5 metres (two metres estimated true width), in diamond drill hole YRM-15-DD-316;
• 135.3 grams per tonne gold over 5.7 metres (4.8 metres estimated true width), including 290.6 grams per tonne gold over 2.6 metres (2.2 metres estimated true width), in diamond drill hole YRM-15-DD-313;
• 123.0 grams per tonne gold over 4.2 metres (3.1 metres estimated true width), including 324.0 grams per tonne gold over two metres (1.5 metres estimated true width), in diamond drill hole YRM-15-DD-307;
• 48.3 grams per tonne gold over 6.9 metres (six metres estimated true width), including 248.0 grams per tonne over 0.9 metre (0.8 metre true width) and including 66.0 grams per tonne over 0.9 metre (0.8 metre estimated true width), in diamond drill hole YRM-15-DD-314;
• 30.0 grams per tonne gold over 9.2 metres (7.5 metres true width), including 116.7 grams per tonne over two metres (1.6 metres true width), in diamond drill hole YRM-15-DD-323.

Bagassi South drilling highlights:

• 8.9 grams per tonne gold over 9.4 metres, including 36.1 grams per tonne over 1.2 metres in diamond drill hole YRM-15-DD-BGS-087.

"These latest results from our infill drilling program at the 55 zone continue to demonstrate the high-grade nature of the 55 zone," commented John Dorward, Roxgold's president and chief executive officer. "This information continues to support our model and provides additional resolution on key parts of the mineralized body that will be accessed early in the mine's development. In addition, the strike extent at Bagassi South has been extended by 30 metres to the south east with a further broad interval."

55 zone program summary

The 21 holes released today are a part of the company's continuing infill drilling program at the 55 zone, which commenced in the first quarter of 2015. The program consists of a planned 67 holes for a total of approximately 6,000 metres of diamond drilling, to depths of up to 90 metres. Roxgold has so far completed 50 holes in the program for approximately 5,600 metres drilled. The program is estimated to continue through to June, 2015.

These results, incorporated with the results for the six previously released holes (see company disclosure April 14, 2015), represent infill drilling over approximately 300 metres of the strike along the 55 zone. The continuity and the high-grade nature of the results overall continues to support the feasibility resource model with intersections in core being largely consistent with the company's expectations. In places, the additional resolution from the tighter-spaced drilling around the edges of the high-grade domain will allow improved definition of this domain and could lead to potential improvements in the model.

Drilling at the 55 zone is designed to increase drill density in the first year's production areas from 25 metres to 12.5-metre centres. Upgrading the drill density in these key early areas will allow for optimization of the mine plan and provide additional information for advanced design and short-term planning for the first year's production.

applied to 1.5-metre composites within the high-grade domain of the 55 
zone for resource estimation purposes (see company disclosure on April 22, 
2014).

Bagassi South results

Following up on the company's recent results from Bagassi South's regional exploration drilling (see May 5, 2015, press release for more information), Roxgold is pleased to announce the results of the remaining two diamond drill holes from the program.

Diamond drill holes 086 and 087 confirm the extension of the broader QV1 structure a further 30 metres to the southeast where the structure intersects a late crosscutting dike. The dike is believed to be in the order of 30 to 40 metres wide and trends roughly perpendicularly to the QV1 structure. The mineralization encountered in holes 086 and 087 is consistent with previously announced results in drill holes 083-085 extending the strike length of the QV1 extension by approximately 230 metres.

The 2,400-metre program was designed with the purpose of extending the strike length of the QV1 structure at Bagassi South to the southeast of the high-grade mineralization previously encountered in the QV Prime target.

No drilling has been conducted on the southern side of the dike to date, which is a younger crosscutting feature. This area will be a target of a follow-up exploration campaign which is anticipated to commence in June.

* True widths for QV1 intersections are estimated to be between 85 and 90 
per cent of reported core intervals.

The QV1 target at Bagassi South is located 1.8 kilometres to the south of the 55 zone where Roxgold has recently commenced construction activities. No resources have yet been estimated for the QV1 target at this time.

Qualified person

Ben Pullinger, PGeo, vice-president of exploration for Roxgold, a qualified person within the meaning of National Instrument 43-101, has verified and approved the technical data disclosed this press release. This includes the sampling, analytical and test data underlying the information.

Quality assurance/quality control

Drill holes reported in this press release were drilled using NQ-sized diamond drill bits. Company employees are located at the drill site. Contractors and employees of Roxgold conducted all logging and sampling. The core was logged, marked up for sampling using standard lengths of two metres outside of the zone and adjusted to lithological contacts up to one metre within the zone. Samples are then cut into equal halves using a diamond saw. One-half of the core was left in the original core box and stored in a secure location at the Roxgold camp within the Yaramoko area. The other half was sampled, catalogued and placed into sealed bags and securely stored at the site until it was shipped to Act Labs in Ouagadougou. The core was dried and crushed by the lab and a 150-gram pulp was prepared from the coarse crushed material. The lab then conducted routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish. Samples returning over five grams per tonne were also analyzed by gravimetric analysis. Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the lab inserted its own quality control samples.
