Kobo’s primary objective is to focus on the exploration and development of the Kossou Gold Project, (permit PR0852) which covers 147.365 km2. The Kossou Gold Project is located in the Yamoussoukro and Bouaflé regions of central Côte d’Ivoire. The permit is located approximately 22 km to the northwest the capital city of Yamoussoukro and 250 km the financial capital of Abidjan. Importantly, key gold showings are located within 7 to 10 kilometers of the Yaouré Mine open pits and process facility and are connected by a well-established road.

First Diamond Drill Program at the Kossou Gold Project Underway in 2024

The Company has commenced approximately 4,000 to 5,000 m of diamond drilling on the Road Cut Zone, Jagger Zone and Kadie Zone as part of the first phase of its 2024 exploration program at the Kossou Gold Project. The 2024 drill program is designed to follow up on results from the Company's inaugural 2023 exploration program which identified multiple shear zones of gold mineralisation in three key targets with a combined strike length of over four kilometres. 

The main objective of the 2024 drill program is to rapidly advance the Road Cut Zone, Jagger Zone and Kadie Zone by testing the Comapny's growing understanding of the structure and controls to gold mineralisation at these key targets. The Company is drilling a significant portion of the soil geochemical anomaly at the Road Cut Zone that was previously inaccessible and to complete the first drill holes at the Kadie Zone, which appears to demonstrate excellent exploration potential.     


Proximity to Nearby Operator Considered an Asset

Our immediate proximity to the Yaouré Gold Mine operated by Perseus Mining gives Kobo a significant advantage in terms of development options as the Company progresses the project. There is significant infrastructure already in place which provides Kossou with potential options if an economic deposit can be delineated.

The Yaouré Gold Mine is reported to contain gold resources (Measured and Indicated) of 2.8 million ounces (1.59 g/t Au), with 2.07 million ounces in Proven and Probable Reserve (1.73 g/t Au). The most recent feasibility study completed on the project concluded an 12.5-year mine life with an all-in sustaining cost of $1,116 per ounce (www.perseusmining.com).

Inaugural 2023 Drill Program a Success 

Kobo has completed initial drilling at its Kossou Gold Project located in Cote d’Ivoire, West Africa with 5,887 metres drilled in 53 reverse circulation drill holes and 80 trenches (~5,492 m). Drilling and trenching has successfully confirmed significant gold mineralisation at the Road Cut Zone and additional strong gold mineralisation within the Jagger Zone. Further exploration work has elevated the Kadie Zone to potential drill status.    

Jagger Zone

The Jagger Zone represents the largest and strongest soil geochemical anomaly yet discovered at Kossou. The Company completed a total of 25 RC drill holes for 3,164 m and has recorded gold mineralisation in drilling over a total strike extend of 1,400 m. Significant gold mineralisation has been intersected in each hole drilled to date.

Jagger continues to show broad zones of gold mineralisation with higher grade sections within a strong north-south shear zone. High grade gold mineralization is associated with N-S shear parallel brecciated veins and east-west to northwest trending quartz veins within silicified shear zones at the Jagger Zone. The brecciated vein material at this target has been mapped over 700+ m strike length.

The Road Cut Zone (RCZ)

The RCZ was initially discovered during early reconnaissance of the Permit and lies within strongly altered volcanic rocks heavily cut by quartz and quartz-carbonate veins/veinlets. The Company completed 1,699 m of RC drilling in 13 holes and has defined broad zones of gold mineralisation with high grade sections hosted within sheared and silicified volcanic units over a strike length of 850 m.

Gold mineralisation has been confirmed in clearly defined mineralised zones to a depth of 80 m below surface. Gold in soil geochemistry indicates that this target can be traced over a strike length of 1.7 kilometers and is a prime target for continued drilling. Results from trench KTR070 demonstrate the potential of the Road Cut Zone anomaly.

The Kadie Zone

Recent infill soil sampling has identified three strong geochemical anomalies 200 m, 400 m, and 600 m west of the main Jagger Zone named Kadie 1, Kadie 2, and Kadie 3. The Kadie Zone targets have structural and lithological characteristics similar to those found at the prospective Jagger gold bearing shear zone.

The total combined strike extend of these anomalies totals approximately 750 m.

Summary of Initial 2023 Drill Program Results


Historic Drilling

Kobo began exploration efforts in 2016 initially examining an alluvial/eluvial deposit in what is designated the “Beach Zone”. A series of 164 pits were dug and the contents of the pits were hand washed for evidence of gold. All but nine pits contained visible gold.

Subsequent mapping and prospecting work led to the discovery of the RCZ. Strong rock sampling results and early soil geochemical survey results showed indications of significant potential mineralisation which led Kobo to expand this exploration program.  Additional mapping, rock and soil sampling and trenching resulted in the delineation of at least 7 significant zones of potential gold mineralization. Exploration work is ongoing.


Kobo has collected 3,700+ soil samples excluding blank and duplicate samples. Gold in soil geochemical results have outlined multiple anomalous trends including:

  • Beach-RCZ ~ 1.6 km strike
  • Jagger Zone ~1.8 km strike (up to 500+ m width)
  • Jagger Zone South ~2.8 km strike
  • Kadie Zone ~ 750 m in three distinct anomalies 

All geochemical targets are supported with rock samples or extensive artisanal mining. These geochemical targets, along with trenching and surface mapping formed the basis of the 2023 drill program.


Airborne Magnetics (Drone) Survey 

Between August 13 and August 28, 2020, a 1,195.4 km Unmanned Aerial Vehicle (“UAV”) magnetic survey was completed over a portion of the permit by MWH Geo-Surveys International Inc. of the USA (“MWH”). MWH utilized a DJI M600 Pro drone, a Geometrics MagArrow (cesium vapor magnetometer) and GEM System GSM19 base station. Survey lines were flown on 50 m spacing and at a mean terrain clearance of 62.3 m.


Magnetic Data

Processing and analysis of the survey results have shown good correlation with geochemical, trench and surface rock sampling results and have aided in an advancement of the geology of the project. 


Geological and Structural Study

In March 2021, Kobo contracted InnovExplo to carry out a field mapping and a structural study to gain a better understanding of the local geological environment and controls on mineralisation.  Result of the study were very positive.

Geological observations and structural data indicate a structural corridor that links kn showings and is coincident with both the magnetic interpretation, rock and soil sampling results.  The work also postulated a second structural corridor west of the main area of interest, linking the newly discovered Kilo and Shadow zones.

Gold mineralization occurs within quartz and quartz/carbonate veins/veinlets and disseminations in the host volcanic rocks associated with tensional ‘en echelon’ and conjugate shear and fracture networks.
