TORONTO, July 19, 2017 /CNW/ - Roxgold Inc. ("Roxgold" or the "Company") (TSX: ROXG) (OTC: ROGFF) is pleased to announce an updated Mineral Resource Estimate ("MRE") and complete drilling results from the Company's first half ("H1") 2017 Infill and Extensional drilling program at the Bagassi South deposit which is located less than two kilometers from its flagship underground gold mine at the 55 Zone. The MRE was undertaken by Roxgold and validated by SRK Consulting (Canada) Inc. ("SRK") of Toronto and is based on 250 core boreholes totalling approximately 55,660 metres of drilling and has been prepared in accordance with National Instrument 43-101 ("43-101") Standards of disclosure for Mineral Projects.
Highlights:
The 2017 Bagassi South drilling program returned a significant number of high grade intercepts which have been incorporated into an updated MRE. Below are the highlights of the estimate:
Following the successful infill and extensional drilling program in the first half of 2017, the updated Bagassi South MRE is a significant improvement over the previous inferred resource estimate of 563,000 tonnes at 12.1 g/t Au for 220,000 at a cut-off grade of 5.0 g/t Au (see press release dated April 27, 2017).
"Yaramoko has again delivered high grade resources," commented John Dorward, President and CEO of Roxgold. "As we continue to focus on delivering growth at Yaramoko through development projects and exploration, we are encouraged to have a second high grade indicated mineral resource on the Yaramoko permit that highlights the prospectivity of the permit and Roxgold's potential for organic growth."
Bagassi South Mineral Resource Estimate
The reported mineral resources have been estimated using a geostatistical block modelling approach informed by capped composited gold assay data collected in core boreholes. Resource domains were constructed as implicit wireframes using interval selections of assay and lithological data.
The MRE was undertaken by Roxgold's mine site personnel under the supervision of Yan Bourassa, P.Geo (APGO #1336), VP Geology for Roxgold Inc., a Qualified Person within the meaning of National Instrument 43-101. The MRE was reviewed by Sébastien Bernier, PGeo (APGO #1847) from SRK Consulting (Canada) Inc. ("SRK") of Toronto. SRK is satisfied that work carried out by Roxgold has been conducted in a manner consistent with generally recognized industry best practices and, therefore, the exploration drilling data are sufficiently reliable for the purpose of supporting a mineral resource evaluation.
The exploration database up to June 6th, 2017, comprises 250 core boreholes for a total of approximately 56,660 metres. The geological modelling consists of shear zone envelopes and quartz vein mineralized structures. Individual wireframes were constructed using logged intervals. Two shear zones were modelled for the QV1 and QV' (QV prime) structures, while four individual gold-bearing quartz vein structures were modelled within the QV1 shear zone and one gold-bearing quartz vein structures was modelled within the QV' shear zone.
Borehole gold assay data inside the resource domains were extracted and examined for determining an appropriate composite length. A modal composite length of 1.0 metre was applied to all data, honouring the boundary of the lower grade shear zone and the quartz vein structure sub-domains. The spatial distribution of the gold composites was assessed using variograms and gold grades were estimated into a block model using ordinary kriging informed by capped composites for the QV1 structure and ID4 for the QV' structure.
The impact of gold outliers was examined on composite data using log probability plots and cumulative statistics. Composites affected by capping were further examined in three dimensions to validate their location and relevance relative to the entire population. Individual domains were capped based on statistical distribution. For the QV1 structure, domains were capped at values between 30 g/t and 60 g/t gold while the QV' structure was capped at a value of 82 g/t gold.
Block model quantities and grade estimates were classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 2014). Mineral resource classification is typically a subjective concept, and industry best practices suggest that resource classification should consider the quantity and quality of exploration data supporting the estimates, the confidence in the geological continuity of the mineralized structures, the geostatistical confidence in the tonnage and grade estimates, and the continuity at the reporting cut-off grade. Appropriate classification criteria should aim to integrate these concepts to delineate regular areas at a similar classification.
SRK is satisfied that the geological model constructed for the Bagassi South gold deposit honors the current geological information and knowledge. The location of the samples and the analytical data are sufficiently reliable to support resource evaluation and do not present a risk that should be taken into consideration for classification. The mineral resource model is informed by data from core boreholes drilled with pierce points generally spaced approximately 25 metres apart. The controls on the distribution of the gold mineralization are sufficient to infer reasonable continuity of the gold mineralization between sampling points within the meaning of CIM Definition Standards for Mineral Resources and Mineral Reserves.
Bagassi South Mineral Resource Estimate Statement
Estimated Indicated Gold Mineral Resources at Bagassi South increased to 352,000 tonnes at 16.6 grams of gold per tonne ("g/t Au") for approximately 188,000 ounces of gold at a cut-off grade of 5.0 g/t Au as of July 19, 2017. There was previously no Indicated Mineral Resources disclosed at Bagassi South.
Estimated Inferred Mineral Resources decreased from 220,000 ounces of gold as of December 31, 2016 to 69,000 ounces of gold as of July 19, 2017, due to the conversion of 188,000 ounces of gold from Inferred Resources to Indicated Resources. The grade of the Inferred Mineral Resources increased from 12.1 g/t Au as of December 31, 2016 to 16.6 g/t Au as of July 19th, 2017.

Bagassi South Drilling
The latest drilling program which was completed in Q2, totalled approximately 29,160 meters over 136 holes at Bagassi South with 117 holes drilled along the QV1 structure and 19 holes drilled along the QV Prime structure ("QV1'" or "QV'") structure. The program was primarily designed to infill the QV1 structure with sufficient additional intercepts to support the conversion of the existing inferred MRE to indicated status, ahead of its potential inclusion in a feasibility study which is currently scheduled to be completed in the fourth quarter of 2017.
A secondary goal of the drilling program was to test the extent of the recently identified mineralized shoot along the QV' structure which is located approximately 130 meters to the north east of QV1. Within the updated MRE, the QV' structure accounts for approximately 36,000 ounces of the global Bagassi South inferred resources and the structure remains open down plunge along the contact between the basalt flows and the Bagassi granite.

Exploration Outlook
Exploration activities are expected to continue for the remainder of 2017 to support the Company's organic growth strategy with an approved budget of $8 million.
Pole-Dipole and IP Geophysical Surveys
The ground geophysical survey which is currently underway consists of two pole-dipole gradient surveys and two conventional induced-polarization ("IP") surveys. The two pole-dipole surveys are being conducted over portions of the concession where the 2014 IP survey highlighted areas of disruption in the regional structural fabric that are associated with deposits at 55 Zone and Bagassi South.
The largest pole-dipole survey is covering an area along the Yaramoko Shear Zone that includes both the 55 Zone and Bagassi South deposits, an area referred to as the Bagassi Corridor. The aim of the survey is to outline the western extension of the gold hosting structures and identify sub-parallel structures between the two deposits, south of the Bagassi QV1 structure and north of the 55 Zone.
Regionally, the Bagassi South structures are located in the footwall of the Yaramoko shear zone and are hosted within the Bagassi granite which is a similar geological and structural setting as observed at the 55 Zone. Intrusive granitic plugs are the main host rock for gold mineralization at Yaramoko.
Approximately 6,000m of planned drilling commenced at the beginning of Q3 to target the QV1 Extension structure and the Ridge Line structures along the Bagassi Corridor which the Company hopes will build upon the successful infill drilling program undertaken in the first half of 2017. For the pole-dipole array of the Bagassi Corridor survey please refer to the following link (Figure 3).
Historical drill results along the Bagassi Corridor to the south of the QV1 structure include several high-grade drill intercepts located outside of the current Bagassi South mineral resource estimate:
The two-conventional induced-polarization ("IP") surveys have been planned to cover areas that are located west and north-west of the 2014 IP survey. The first conventional IP survey was completed in June and was conducted over the Boni Shear Zone, a regional structure which hosts Semafo's Siou deposit approximately 10 km to the north of Yaramoko. A 10,000m drilling program along the Boni Shear Zone is budgeted to begin in Q4 over the five chargeable anomalies defined by the survey. For the Boni Shear Zone induced-polarization ("IP") survey, please refer to the following link (Figure 4).
The second conventional IP survey will be conducted over a granite-mafic volcanic contact located west of 55 Zone and Bagassi South that exhibits similar structural settings as the Yaramoko Shear Zone. The Houko survey covers the central western portion of the Yaramoko exploration concession and a portion of the Houko concession. The Houko survey is expected to be completed in early Q3 and areas of interest will be followed-up by auger drilling.
55 Zone Exploration Update
At 55 Zone, a further round of drilling, totaling approximately 11,000 meters was commenced in the second quarter and will continue into the third quarter. There are currently two drill rigs active on the 55 Zone deep drilling program and this program will primarily target resource growth at depth, below and west of the Q4 2016 drilling program which featured the widest interval ever drilled at Yaramoko in Hole YRM-16-DD-426 of 20.1g/t Au over 23.8 meters (see press release dated November 29, 2016).
Upcoming Catalysts

Qualified Persons
Yan Bourassa, P.Geo, VP Geology for Roxgold Inc., a Qualified Person within the meaning of National Instrument 43-101, has verified and approved the technical disclosure contained in this press release. This includes the QA/QC, sampling, analytical and test data underlying the information. For more information on the Company's QA/QC and sampling procedures, please refer to the Company's AIF dated April 5, 2016.
Quality Assurance/Quality Control
The holes were drilled with NQ2 sized diamond drill bits for drill holes reported in this press release. Company personnel are located at the drill site. 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 Activation Laboratories located in Ouagadougou (the "Lab"). 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 5.0 g/t were also analysed 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.
