TORONTO, ONTARIO–(Marketwired – April 3, 2017) – Teranga Gold Corporation (“Teranga” or the “Company”) (TSX:TGZ)(ASX:TGZ) is pleased to announce the second round of results from its ongoing 115-hole drill program at its Niakafiri deposit, situated within 5 kilometres of the mill on the Company’s Sabodala mine license in Senegal, West Africa.
HIGHLIGHTS
- Drill results from the first 60 holes at the Company’s Niakafiri deposit extend the mineralisation along strike and at depth, providing potential for re-optimization of the life of mine plan.
- Positive drilling success in the Niakafiri Main zone includes the following highlight intervals from the 33 holes released today representing some of the widest mineralised intervals encountered within the Niakafiri deposit to date:
- 4.18 g/t Au over 23 metres including 6.52 g/t Au over 12 metres in MDD17-279
- 2.99 g/t Au over 33 metres including 4.23 g/t Au over 17 metres in MDD17-277
- 2.41 g/t Au over 29 metres including 6.51 g/t Au over 6 metres in MDD17-281
- 3.19 g/t Au over 21 metres at the end-of-hole in MDD17-284
- Results from the first 27 holes were released February 27, 2017 and include:
- 6.90 g/t Au over 8 metres including 45.5 g/t Au over 1 metre in MDD17-242
- 2.45 g/t Au over 17 metres including 3.25 g/t Au over 11 metres in MDD16-235
- 1.89 g/t Au over 12 metres including 5.25 g/t Au over 3 metres in MDD17-239
“The drill results confirm our belief that there is considerable opportunity to extend the mineralisation both along strike and to depth at Niakafiri,” said Paul Chawrun, Chief Operating Officer of Teranga. “These encouraging results could result in the re-sequencing of Niakafiri in the current mine plan, filling in the production gaps at Sabodala to extend the life of open pit mining and to defer the start of underground mining.”
“We are very pleased with our most recent results, which represent some of the widest mineralised intervals encountered within the Niakafiri deposit to date,” stated David Mallo, Vice President Exploration of Teranga. “Our drill program at Niakafiri will continue to focus on extending the mineralisation along trend and to-depth.”
Since re-initiation of this program with one (1) drill in late 2016, the Company has increased the number of drills to four (4). The current phase of the Niakafiri drill program, 115 proposed core holes totaling 12,000 metres, is ongoing at both the eastern and western components of the Niakafiri deposit (see Figure 2 in Appendix 1). Drill results received to date will be included in a mid-year resource and reserve update. The balance of the current year program will be included in a year-end resource and reserve update.
The majority of the Niakafiri deposits were delineated at the inception of the Sabodala project in 2009 and they represent a combined measured and indicated resource of approximately 600,000 ounces, an inferred resource of approximately 220,000 ounces and reserves of over 300,000 ounces(1) included within the total resource estimate (see Tables 1A and 1B in Appendix 1). The Niakafiri deposits are within 5 kilometres of the Sabodala mill (see Figure 1 in Appendix 1).
Niakafiri East
The results received to date from the eastern portion of the Niakafiri deposit drilling (see Figure 2 in Appendix 1) are encouraging. They fill in gaps between previously outlined resource pit shells, extend mineralisation up-dip in a number of areas of the deposit and fill in previous widely spaced drill intersections.
In addition, there have been positive results from a set of drill holes targeting the down-dip depth extent of the existing reserve and resource pit shells in the central portion of Niakafiri Main (Table 1 on the next page highlights many of these results). These deep mineralised intersections extend as far as downhole to 270 metres (approximately 200 metres below surface), and are the deepest intersected at Niakafiri Main to date, with mineralisation remaining open at depth. Examples of this down-dip drilling success in central Niakafiri Main are shown in two representative drill sections as Figures 3 and 4 in Appendix 1.
The most advanced portion of Niakafiri is the eastern component – Niakafiri Main, Niakafiri Southeast and Dinkokono – where the first phase of planned drill holes is now complete. A second phase drill program will follow-up on these successful initial drill results focusing primarily in the vicinity of the wider mineralised intervals in the central portion of Niakafiri Main.
Niakafiri West
In addition to the ongoing drill program on Niakafiri East, drilling has begun on the western component of the resource – Niakafiri West and Soukhoto. The objectives at Niakafiri West are to upgrade the resource categories from inferred to indicated, and potentially to fill in the current gap of approximately 1.5 kilometres extending northwards towards known mineralisation at Soukhoto. An additional phase of drilling will be undertaken based on interpretation of the results from the current program.
Pending further favourable results at Niakafiri, the Company expects to evaluate the impact on pit sequencing in the life of mine plan and the timing of village relocation.

APPENDIX 2
JORC Code, 2012 Edition – Table 1 Report
Section 1: Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections)
Criteria | 2012 JORC Code explanation | Commentary | ||
Sampling techniques | – Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc.). These examples should not be taken as limiting the broad meaning of sampling. | – A total of 115 Diamond Core holes (DD) for 12,000 m are planned for the current drill program at Niakafiri. Results from 33 holes are reported herein. The first 27 holes were reported in a previous Company news release (February 27, 2017). Sampling is half core from the DD drilling. | ||
– Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. | – Drill core was sawn in half over defined 1-metre sampling intervals with one half retained and one half sampled and assayed for gold. Oriented core markings were used as guides for sawing. |
|||
– Aspects of the determination of mineralisation that are Material to the Public Report. | – Initially all core is sampled along the entire hole to determine the nature of mineralisation and relationship to logged lithology, alteration and structure. Based on the detailed sampling results, mineralisation zones were defined with additional drilling and sampling, specifically across the mineralisation and along the mineralised shoulders on either side. |
|||
– In cases where ‘industry standard’ work has been done this would be relatively simple (e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases, more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure of detailed information. | – Industry standard analytical techniques have been utilized. | |||
Drilling techniques | – Drill type (e.g. core, reverse circulation, open- hole hammer, rotary air blast, auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc.). |
– A diamond core drilling program is being conducted. Diamond drill holes are drilled using standard HQ or NQ sized rods. Wider diameter HQ core is utilized through the upper oxide and transitional portions of the stratigraphy and size reduction occurs to NQ in fresh material. Oriented core is utilized once appropriate NQ core size is being drilled. | ||
Drill sample recovery | - Method of recording and assessing core and chip sample recoveries and results assessed. |
– Diamond core recoveries are measured and recorded for each 1-metre sample interval. Core was sampled on nominal 1 m intervals. | ||
– Measures taken to maximise sample recovery and ensure representative nature of the samples. | – Diamond drill contractor has experience in drilling within the geologic host environment and all measures to maximize recoveries are employed. | |||
– Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. | – There is no evidence to suggest a relationship between sample recovery and grade as there is no significant loss of material. Sample recoveries are of very good quality. | |||
Logging | – Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. | – Core samples were geologically and geotechnically logged following established standard operating procedures and includes sufficient and appropriate detail to support Mineral Resource estimation, mining and metallurgical studies. | ||
– Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. | – Logging is qualitative in nature. All core is photographed to provide a continuous record. Half core is also stored for future reference and utilization. | |||
– The total length and percentage of the relevant intersections logged. | – All recovered core is logged in detail. | |||
Sub-sampling techniques and sample preparation | – If core, whether cut or sawn and whether quarter, half or all core taken. | – Drill core sampling is undertaken on clearly marked standardized 1-metre intervals then cut in half with a diamond saw along the core length following orientation lines. Half core is analyzed over one-meter lengths. | ||
– If non-core, whether riffled, tube sampled, rotary split, etc. and whether sampled wet or dry. | – Not applicable – all core drilling. | |||
– For all sample types, the nature, quality and appropriateness of the sample preparation technique. | – Core handling is closely monitored under standard industry methods from drill to lab. Sample preparation procedures at the analytical lab are also industry standard and closely monitored. | |||
-Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples. | – Standard Reference Materials (Various Standards and blind Blanks) are inserted into the sample stream at industry accepted intervals. Blind sample duplicates are also collected. | |||
– Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. | – Field duplicate data indicates acceptable variability indicating coarse gold is not a significant issue in the sampling. | |||
– Whether sample sizes are appropriate to the grain size of the material being sampled. | ||||
Quality of assay data and laboratory tests | – The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. | – Gold assays for half-core samples form the core drilling were obtained from the independent SGS operated lab on-site at the Sabodala Mine facility which provides an AA (Atomic Absorption) finish gold result. Selected samples from mineralised intervals are periodically re-analyzed at the independent ALS lab in Johannesburg, South Africa to provide an FA (Fire Assay) finish. | ||
– For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. | – Not applicable. | |||
– Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (ie lack of bias) and precision have been established. | – Certified reference materials (SRM’s), blanks and duplicates are regularly inserted into the sample preparation and analysis process with approximately 10% of all samples being related to quality control. | |||
– Data is reviewed before being accepted into the database. Any batches failing QAQC analysis are resubmitted for check assays. Dataset QAQC contains acceptable levels of precision and accuracy. | ||||
Verification of sampling and assaying | – The verification of significant intersections by either independent or alternative company personnel. | – All results and all significant intersections have been reviewed by staff geologists to check the geological context. | ||
– The use of twinned holes. | – Some twin core holes have been undertaken in this program to verify and confirm previous RC drilling results. | |||
– Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. | – All sample and recovery data is recorded to paper and electronic forms at the time of logging. Geological logging is directly logged into template log sheets by Toughbook computer. The templates are then provided to an internal database manager for loading in database management software. Referential integrity is checked as part of the data loading process. | |||
– Discuss any adjustment to assay data. | – No adjustments were made to assay data returned from the laboratory. | |||
Location of data points | – Accuracy and quality of surveys used to locate drill holes (collar and down-hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. | – Drill hole collar locations were surveyed by trained site based technicians using real time differential GPS (DGPS) to a sub decimetre accuracy in horizontal and vertical position. Vertical precision was supplemented using a Digital Surface Model. Down hole drill hole surveys were undertaken by the drill contractor utilizing a Reflex EZ-Shot downhole survey instrument. Survey intervals were collected at collar, periodic intervals down the hole and end of hole were routinely collected. | ||
-Specification of the grid system used. | – Both UTM and mine-grid systems are utilized for locating drill collar locations. | |||
– Quality and adequacy of topographic control. | – Tographic control is based on the Digital Surface Model. The quality and accuracy of topographic control is considered to be reasonable. | |||
Data spacing and distribution | – Data spacing for reporting of Exploration Results. | – Drilling is nominally on a 40 m by 40 m spacing, with exceptions based on data interpretation. | ||
– Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. | – Geological interpretation based on drill spacing has identified continuity of geology and grade and is determined to be sufficient for estimating Mineral Resources and Mineral Reserves. Experimental variograms generated for mineralised zones with sufficient data, have confirmed the grade continuity ranges based on the drill hole spacing. | |||
– Whether sample compositing has been applied. | – Diamond drill core were sampled on nominal 1 meter intervals down the hole, and assayed. Sample compositing was not applied during the current exploration drilling program. | |||
Orientation of data in relation to geological structure | – Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. | – Drill hole azimuths and dips have been oriented perpendicular to the interpreted mineralised zones in order to intersect the true widths of the zones as closely as possible. Occasionally, drilling was planned at oblique angles when the mineralisation trends were not yet well defined or if the optimal collar location was not accessible. Generally, the majority of drilling is oriented such that the sampling of mineralisation is unbiased. | ||
– If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. | – The small percentage of holes oriented oblique to the mineralisation are located in areas with sufficient drill density oriented perpendicular to mineralisation, and will not introduce a significant sampling bias. |
Sample Security | – The measures taken to ensure sample security. | – Samples are removed from the field immediately upon drilling and stored in a secure compound for sub sampling and preparation for lab dispatch. Samples are delivered directly from the site logging / sampling facility to the on site SGS laboratory or the ALS laboratory in South Africa using securely sealed sample bags and a secure chain of custody. Sample submission forms are sent in paper form with the samples as well as electronically to the laboratory. Reconciliation of samples occurs prior to commencement of sample preparation of dispatches. | ||
Audits or reviews | – The results of any audits or reviews of sampling techniques and data. | – All QA/QC data is reviewed in an ongoing hole-by-hole basis and reported both as per hole and in monthly summaries. All QAQC data has been reviewed by the QP’s for this release. |
Section 2: Reporting of Exploration Results | ||||
(Criteria listed in the preceding section also apply to this section.) | ||||
Criteria | 2012 JORC Code explanation | Commentary | ||
Mineral tenement and land tenure status | – Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. | – Drilling reported here has been completed at the Niakafiri deposit area of the Sabodala Mine Lease in Senegal, West Africa. | ||
– The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. | – Teranga Gold Corporation is 100% holder of the Sabodala Mine Lease. | |||
– No historical sites, wilderness or national parks are located in the Mine Lease area. Portions of Niakafiri occur within the limits of the Sabodala village. | ||||
– Tenure is considered very secure. | ||||
Exploration done by other parties | -Acknowledgment and appraisal of exploration by other parties. | – The majority of the Niakafiri deposit area exploration and resource estimation has been conducted by Teranga Gold Corporation. Two portions, Niakafiri Southwest and Niakafiri Southeast, were drilled by Oromin Explorations Ltd, on behalf of the OJVG between 2005 and 2012. Teranga acquired the OJVG in 2013. | ||
Geology | – Deposit type, geological setting and style of mineralisation. | – The Sabodala Gold Project (Mine Lease and Regional Permits) covers greenstone belts and intra belt granitoids of the Proterozoic Birimian Shield. The oldest rocks within the concession are interpreted to be tholeitic to calc-alkaline basalts, andesites and volcaniclastic sediments. Predominately mafic, volcano-sedimentary packages dominate the younger parts of the local stratigraphy. Numerous phases of plutonic activity have intruded the earlier sequences ranging from gabbroic to granitic in composition. Known mineralisation is structurally controlled and widely associated with silicification, quartz veining, iron carbonate, sericite, pyrite and locally albitic alteration. Both the mafic volcano-sedimentary packages and the coarse grained intrusive rocks host significant mineralisation in the project area. | ||
Drill hole Information | – A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
– easting and northing of the drill hole collar – elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar – dip and azimuth of the hole – down hole length and interception depth – hole length. |
– All drill hole collar locations, azimuth, dip and gold assay intercept data received to date is available on the Teranga Gold company website at http://www.terangagold.com/. All same information for the current drill program results are designated within the assay Tables herein. | ||
– If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. | – Not Applicable. | |||
Data aggregation methods | – In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high-grades) and cut-off grades are usually Material and should be stated. | – Gold intercepts are reported as length-weighted average grades in grams per tonne, with a maximum of 2 metres internal dilution and no external dilution. Assays are not capped prior to averaging. A 0.4 g/t Au minimum cut-off grade per sample was applied for all reported intervals. | ||
– Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. | – Grade intersections and inclusive higher grade intersections are reported separately and available on the Teranga Gold company website at http://www.terangagold.com/. Similarly, higher grade intervals within the broader reported intervals have been separated and designated within the Tables herein. | |||
– The assumptions used for any reporting of metal equivalent values should be clearly stated. | – Not Applicable. | |||
Relationship between mineralisation widths and intercept lengths | – These relationships are particularly important in the reporting of Exploration Results. | – Down hole core lengths are reported, as true widths have not yet been determined. | ||
– If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. | – Not Applicable. | |||
– if it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width not known’). | – Is included within the Tables herein. | |||
Diagrams | – Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. | – A detailed Plan view map of drill hole collar locations, (Planned and Completed) for the Niakafiri drill program is available in Appendix 1 herein. Representative Sections form the current drilling program are also included in Appendix 1 herein, of this news release. | ||
Balanced reporting | – Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high-grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. | – A comprehensive listing of all significant gold intercept results for all of the 33 holes reported in this press release is presented in a complete Table of results in Appendix 1 herein, of this press release. Results for all 60 holes completed at Niakafiri during this current program are listed in a Table on the Company’s website at http://www.terangagold.com/ | ||
Other substantive exploration data | – Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. | – No other meaningful or material exploration data has been collected.in reference to this current exploration drilling program at Niakafiri. | ||
Further work | -The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). | – All data will be compiled and analysed for future follow-up programs at the Niakafiri deposit area, initially towards generating an updated resource estimation for H2 2017. | ||
– Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. |
