MM and Obi Prospects
Extensional and Infill Drilling
An 11-hole, 2,300m diamond drill program was undertaken to test for extensions to the mineral resource in several areas of the MM Prospect. In general, the program targeted areas in fresh rock that were down-dip and adjacent to high-grade modelled shoots supported by strong drill intersections. Small portions of the drilling also tested for strike extensions to the mineral resources in oxide material.
The primary focus of the program was in the deepest part of the mineral resource at the central area of the MM Prospect where mineralisation grading up to 14.5g/t Au over mineable widths was previously intersected (refer Sarama news release August 12, 2012). This part of the mineralised system is open and presents an opportunity to define further high-grade material.
The new drilling in this area stepped out approximately 100m along strike to the north and also investigated the potential for footwall repetitions of the high-grade lodes (refer Figures 1 & 2). In general, the drilling returned moderately broad, higher-grade intersections confirming the mineralization model and demonstrating the potential to increase the strike of drill defined mineralisation in the area. Of note is the intersection of 13.7m @ 5.67g/t Au in DDH086 at a vertical depth of approximately 370m, which is hosted in sericite-albite-altered sedimentary rock, rather than the more prevalent porphyry host, and sits in the footwall of the main mineralized porphyry lodes of the system.
Full results are listed in Appendix A with highlighted downhole intersections including:
- 13.7m @ 5.67g/t Au from 429m in DDH086;
- 4.4m @ 4.54g/t Au from 413m in DDH044; and
- 4.0m @ 2.75g/t Au from 445m in DDH004.
The intersection in DDH086 may represent a high-grade mineralized oblique fault structure and requires further drill definition. Brecciation was also noted in the zone of higher grade mineralisation in DDH044, further illustrating the possibility of structural features influencing grade distribution. The strength of these results and their reinforcement of previous high-grade intersections further highlights this zone as a compelling exploration target.
Drill testing for down-dip extensions to the mineral resource in the southern part of the MM Prospect was also successful in confirming the continuity of porphyry-hosted mineralisation over broad widths. Higher-grade zones are present within the overall broad porphyry intersections, suggesting continuation of the mineralised system past the 400m vertical depth drilled in this area. Further work on the controls of the higher-grade shoots will be used to inform future targeting strategy in this area. Highlighted intersections from this portion of the drilling include:
- 13.7m @ 1.62g/t Au from 470.8m, including 6.7m @ 2.95g/t Au from 471.3m; and
- 6.1m @ 1.61g/t Au from 487.5m, including 3.5m @ 2.51g/t Au from 490m in FRC879RE1.
A 5-hole program, comprising 300m of diamond and 400m of RC drilling was undertaken at the MM and Obi Prospects in selected areas where recent geophysical surveys indicated potential for additional mineralisation and/or alternative interpretations in areas of known geological complexity.
The results of the program largely support existing interpretations and grade estimation of the mineral resource, and the new data will be incorporated in future mineral resource updates. Full results are listed in Appendix A.
Extensional and Infill Drilling – High-Grade Oblique Lode
Follow-up drilling to investigate strike and depth extensions was conducted on a high-grade, oblique mineralised lode located in the central area of the MC Prospect (refer Figures 1, 3 & 4). The lode is part of the mineral resource and was defined by previous drilling campaigns to be striking at approximately 070°, which is oblique to the main north-north-east (“NNE“) striking porphyry-hosted lodes that transect this lode. The limited strike length of the lode and strength of previous drill intersections indicated potential to extend the mineral resource to the south-west and north-east. Ground based geophysical surveys, including north-south oriented gradient array and sectional induced polarisation (“IP“) surveys were commissioned to assist in drill targeting.
The 11-hole program consisting of 800m diamond and 900m RC drilling tested for strike extensions of approximately 70m in each direction as well as extension to a vertical depth of approximately 220m.
Full results of the program are included in Appendix B, with highlighted intersections of:
- 16m @ 3.04g/t Au from 80m in FRC1042;
- 14m @ 2.37g/t from 82m in FRC1044A; and
- 7m @ 1.70g/t Au from 82m in FRC1043.
The results indicate modest potential for the oblique lode to be extended to the south-west in the upper zone, however shallow drilling to the north-east did not intersect mineralisation of significance. Deeper drilling suggests potential to extend the lode in both directions of strike as well as at depth based on the continuity demonstrated by the deeper intersections in DDH077 (refer Figure 4).
Further assessment of the structural geology will be undertaken in this complex area to reinforce targeting strategies prior to additional drilling. The close proximity of the multiple NNE trending lodes and the oblique target lode presents challenges in drill planning and several results included in Appendix B represent shallow angle intersections of NNE trending mineralisation and are considered secondary to the purpose of the program.
Extensional and Infill Drilling — Other Areas
A separate program of modest size targeting minor extensions to, and infill of, the mineral resource in various areas of the MC Prospect was also undertaken. The results of this 6-hole program (consisting of 600m of diamond and 400m of RC drilling) generally confirmed the existing mineral resource interpretation. Full results are included in Appendix B.
Of note are the multiple intersections in DDH068, including an interval of porphyry-hosted mineralisation at a vertical depth of 340m. While of moderate tenor, this isolated intersection demonstrates continuity in the down-dip direction and indicates that the mineralised system remains open along strike and down-dip. As observed in other areas of the mineralised system, high-grade shoots situated outside of the limited drill area present an opportunity for extensional exploration.
Additional Targets — Cross Structures
A 4-hole, 400m RC drill program targeted oblique mineralisation potentially located in a 300m wide zone separating tracts of NNE-trending mineralisation at the MC Prospect. The drilling was broadly spaced and designed to follow-up on previous reconnaissance drilling supported by recent geophysical surveys. Results from the program are encouraging with several high-grade oxide intersections being returned including:
- 9m @ 3.39g/t Au from 16m; and
- 5m @ 5.25g/t Au from 45m in FRC1051 (refer Figure 3).
Full results are included in Appendix B. Further drilling is required to interpret the orientation and extent of mineralisation in the area.
Phantom Group of Prospects
Phantom East Prospect
A 6-hole, 700m RC drill program was undertaken at the Phantom East Prospect to follow-up higher-grade intersections returned from AC programs in Q1 2016. The area accounts for a small portion of the current mineral resource and is geologically complex with mineralisation possibly being associated with structural features interpreted to strike obliquely (070°) to the main NNE trend. The drilling was designed to confirm existing high-grade intersections and test for strike extensions to the south-west.
The drilling confirmed the tenor of previous drilling and supports the interpretation of several closely spaced, high-grade lodes which are narrow and steeply-dipping. The strike of the mineralisation is inferred to be oblique to the main mineralised trend and largely situated between the historical east-west drill lines. Drilling to the immediate south-west did not intersect significant mineralisation however this may be due to the steep dip of the lodes and divergence of strike relative to the drill lines.
The presence of oblique mineralisation in this lightly-tested area highlights the potential for additions of near-surface high-grade mineralisation to the mineral resource base. Further drilling is required to re-test for strike extensions in this direction in between existing drill lines (Refer Figures 5 & 6).
Full results are listed in Appendix C with encouraging downhole intersections including:
- 5m @ 3.45g/t Au from 85m in FRC1038;
- 4m @ 7.81g/t Au from 85m; and
- 7m @ 4.54g/t Au from 104m in FRC1056.
Note: FRC1056 and FRC1038 were drilled at a shallow angles (<~20-50°) to mineralisation — true width expected to be approximately 25-50% of downhole length
Phantom and Phantom West Prospects
A small 5-hole AC program was conducted at the Phantom and Phantom West Prospects to infill and test for extensions to the mineral resource. Full results are listed in Appendix C.
Isolated Geophysical Targets
A 13-hole program comprising 600m of RC and 2,100m of diamond drilling was undertaken at the MC, MM and Phantom Prospects to test geophysical targets generated from a recent geophysical survey.
The gradient array and pole-dipole IP surveys were undertaken using north-south oriented grid lines which were orthogonal to previous surveys conducted in these areas. The re-orientation was specifically incorporated to enhance imagery of geophysical anomalous zones that were potentially striking sub-parallel to the previous grid.
Several anomalous zones were identified in the re-oriented survey and are interpreted as potential mineralised bodies containing sulphide mineralisation. Many of these anomalies are shallow in depth and are interpreted to dip steeply to the north, which is aligned with other areas of the mineralised system where oblique mineralisation has been defined by drilling.
The drilling successfully intersected sulphide mineralisation at targeted depths, however gold tenors were modest. The results will be used to further develop understanding of the structural architecture of the mineralised system and to calibrate geophysical data with geological observations.
Several encouraging intersections were returned, largely in oxide material and present an opportunity to delineate additional oxide mineralisation to add to the mineral resource base. Full results are included in Appendix D, with a highlighted intersection of 10m @ 1.95g/t Au from 2m in FRC1050.
Sarama’s President and CEO, Andrew Dinning, commented:
“Historically, the principal focus had been to extend the near surface mineral resources but the recent shift to improve our understanding of the fabric and vertical extent of the system has delivered encouraging results.
The deeper, high-grade intersections we are seeing at the MM Prospect further illustrate the potential of the system and flags more options for development including underground mining. Drill testing is very limited, but what has been done shows that we have continuity and economically significant grades at depth.
We firmly believe that the South Houndé Project has the potential to be an open pit and underground mining complex. The Project will play a key role in the development of the southern part of the Houndé Belt where Sarama has significant interests across three projects collectively hosting sizeable gold mineral resources.”

NOTES — DRILLING
Drilling results are quoted as downhole intersections. True widths of mineralisation are estimated to be approximately 70% to 80% of reported downhole intersection lengths, except as otherwise noted. The orientation of some of the mineralised units is not yet well understood.
The reported composites for the drilling were determined using a cut-off grade of 0.30g/t Au to select significant and anomalous intersections, with a maximum of 2m internal dilution being incorporated into the composite where appropriate. No top-cuts were applied to assay grades. Isolated mineralised intersections less than 2m in length have not been reported.
Gold assays for the drilling were undertaken by the ALS Minerals, SGS SA and Bigs Global laboratories in Ouagadougou, Burkina Faso and SGS SA laboratory in Bamako, Mali. Assays are determined by fire assay methods using a 50 gram charge, lead collection and an AAS finish with lower detection limits of 0.01g/t Au (ALS) and 0.005g/t Au (Bigs Global).
The drilling was generally designed using a range of azimuths, according to program aims and mineralization orientation, dipping at -50-55° and were of variable length. Holes were spaced at 25-50m intervals along drill lines. All AC and RC holes were sampled at regular 1m downhole intervals. All diamond holes were sampled according to geological intervals but were generally <1m.
Intersection oxidation state classification is based on visual logging of the drillholes.
Sarama undertakes geological sampling and assays in accordance with its quality assurance/quality control program which includes the use of certified reference materials for AC, RC and diamond drilling as well as field duplicates in the case of AC and RC drilling.
