Komet announces initial Mineral Resource Estimate for the Kabaya Prospect, (Dabia Sud property, Mali)
QUEBEC CITY, Jan. 21, 2019 (GLOBE NEWSWIRE) — Komet Resources inc. (TSX-V: KMT) (“Komet” or the “Company”) is pleased to report an initial mineral resource estimate for the Kabaya gold prospect drill prospect, located in the southern part of its Dabia Sud exploration permit (“the Property”) in Western Mali, West Africa.
Highlights of the Resource Estimate include :
- An Indicated Resource of 3.17 million tonnes (Mt) grading 1.03 g/t for 105,000 contained gold ounces and an Inferred Resource of 0.96 Mt grading 1.14 g/t for 35,000 contained gold ounces at a cut-off grade of 0.40 g/t Au (table 1).
- The pit constrained resource is based on optimized pit shells using a gold price of 1350 US$ and a presumed heap leach gold recovery of saprolite ore.
- Gold mineralization at Kabaya remains open at depth in bedrock and laterally to the south-west and north-west.
- Komet intends to continue the resource definition drilling program in order to further develop the resource laterally in saprolite and at depth in bedrock.

L. Werner Claessens, CEO states : “Komet is pleased to report a maiden resource estimate for the Kabaya Prospect. The resource block model suggests excellent potential for significant extensions of the gold deposit at depth and laterally to the south-west and north-west. This exploration success clearly warrants the continuation of the drill program in order to further expand resources. Moreover the same approach of systematic exploration will be implemented for the other large gold-in-soil anomalies in the north and east parts of the Dabia Sud property with the objective of discovering new gold deposits. From a mining point of view a heap leach scenario is the most viable option to potentially mine this saprolite resource as a startup project”.
Kabaya Resource Estimate
The Kabaya resource estimate is based on analytical data from trenching and several drill campaigns realized in 2012-2013-2014, 2017 and 2018. Five trenches (4 of them East-West and 1 North-South) totalling 515 m, were realized in 2012-2013. All drilling was performed along east-west oriented lines with shallow drill holes inclined 50° to the west and consisted of 91 aircore holes, totalling 5,256 m and 91 RC drill holes, totalling 7,274 m. The database does not include the quality control samples consisting of duplicates, blanks and standards samples, which returned variations within acceptable limits.
The Kabaya gold resource modeling and estimate was independently realized by Yann Camus, P. Eng., SGS Canada Inc. (SGS Geological Services; Blainville, Québec, Canada), a Qualified Person as per NI 43-101 Standards, with reasonable prospects for eventual economic extraction. The estimate was completed at a variety of cut-off grades by SGS Geological Services and the details are presented in the table below :

The Current Resource block model was prepared using the Genesis© mining software. Interpolation was performed using inverse square distance (ID2) in 3 estimation passes with 33 different search ellipses of 11 different orientations which were adapted for the orientation of the deposit. The block model was then fed to GEOVIA’s Whittle™ software to provide a pit-constrained Mineral Resource Estimate. The parameters used to generate the optimized pit are listed below in Table 3.
A modeling cut-off grade of 0.2 g/t Au, a minimum thickness of 3 meters and a minimum accumulation of 1 m.g/t were used to delineate mineralized volumes. In all, 18 mineralized volumes were interpreted and modelled from this data. A total of 118 drill holes and 4 trenches intersect the mineralized volumes. The 1,009 three-meter composites average 1.02 g/t Au (uncapped) and 0.96 g/t Au (capped). The capping was applied to the assays at a grade of 30 g/t. Only 8 assays were capped on a total 2,986 assays in the mineralized zones (0.3% of the assays were capped). The gold loss due to the capping is of 4% for the base case resource. Densities are based on other similar projects and mineralization located in Mali and measurements of 14 field samples. A density of 1.70 t/m3 was used for all the saprolitic mineralization.
The block model has a block size of 5 x 6.25 x 3 metres. Estimation was done by inverse distance squared with ellipsoid influenced distances. A total of 18 separate volumes were estimated with 10 composite sets. Three estimation passes were used with ellipsoids of 25 x 25 x 6 metres, 45 x 45 x 12 metres and 100 x 100 x 30 metres.
The first pass uses a minimum of 5 and a maximum of 6 composites, with a limit of 2 per drill hole. The second pass uses a minimum 7 and a maximum of 8 composites, with a limit of 3 per drill hole. The third pass uses a minimum 1 and a maximum of 8 composites, with a limit of 3 per drill hole. The smoothing of the estimation is adequate. The inferred resource category based on a drilling grid between 30 m and 60 m and the indicated category has been given for mineralization with a drilling grid of 30 m. Mineralized volumes with 2 intercepts or less have been forced to inferred. The current mineralized volumes with indicated resources have a minimum of 4 intercepts.

Dabia Sud Property Geology
The 35 km² large Dabia South Exploration Permit is located in the southeastern part of the Paleoproterozoic Kedougou-Kenieba inlier, covering eastern Senegal and western Mali. This region is underlain by folded and sheared sequences of metasedimentary and metavolcanic facies, which are intruded by felsic and mafic plutons. The region’s structural pattern is predominantly drawn by the north-south oriented regional Senegal-Mali Shear Zone (“SMSZ”) and its associated northeast-trending splay structures, which are spatially related to several major gold deposits such as Fekola, Loulo, Gounkoto and Sadiola.
Past exploration programs, carried out by other companies in the Dabia area, identified geochemical features and litho-structural settings which demonstrated the potential for the discovery of gold mineralized systems. The soil survey performed by Ashanti Mali SA (1997), and completed by Robex over the eastern part of the Dabia permit area (2007) revealed interesting gold anomalous zones in the southern (vicinity of the village Kabaya), eastern and northern (Wallia) areas of the Property. An early exploration trench and drill campaign initially intercepted gold mineralization underneath the Kabaya cluster of soil geochemistry anomalies. The last RC drilling campaigns, realized by Komet (see news releases of August, 23rd 2017 and September 6th, 2018), extended the drill grid north and south of the initial Kabaya prospect and infill drilling completed the drill grid pattern. Drilling defined economic gold mineralization with good grade continuity in the thick weathered rock profile (saprolite) to a vertical depth of 65 m. Two mineralized zones were identified, Kabaya main and Kabaya southwest, stretching at the surface over lengths of respectively 350 m and 150 m. The gold mineralization remains open at depth in bedrock, underneath the saprolite layer, and laterally to the north-west and to the west of the Kabaya southwest zone. The results of a ground gravimetric survey, realized in 2014, suggest a shear zone controlled geological context. The Kabaya gold occurrence could probably be associated with one of the splay structures of the major Senegal-Mali regional shear structure. Study of drill cuttings, artisanal gold pits and rejects and a few rare outcrops provide indications for a geological setting of quartz-vein stockwork and veinlets in a strongly weathered volcano-sedimentary succession.
Follow-up Exploration Drill Program
The company has the intention expanding the Kabaya resource with further drilling around the established block model of the deposit, specifically to test for additional gold mineralization at depth and laterally to the north-west and south-west.
During and after the next drilling campaign a metallurgical program will be designed to determine the mineralogical, metallurgical and communition properties of representative saprolite and bedrock drill rock samples.
Furthermore an auger drill geochemistry survey is planned to test the soil geochemistry anomalous features in the north and center parts of the property. Subsequently exploration RC drilling will be carried out to identify potential new resource zones.
