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.

2023 Drill Program – Fully Funded 

Kobo plans to initiate its fully funded maiden drill program in Q2 2023.  An 8,000 m planned RC drill program will focus on the RCZ, Jagger and CZ zones with additional drilling testing additional gold geochemical anomalies.


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 2.4 million ounces (55.9 million tonnes @1.35 g/t Au), with 1.6 million ounces in Proven and Probable Reserve. The most recent feasibility study completed on the project concluded an 8.5-year mine life with an all-in sustaining cost of $745 per ounce (www.perseusmining.com).

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 Road Cut Zone (“RCZ”). Strong rock sampling results and early indications of significant potential mineralization led Kobo to expand this exploration program and 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.

Jagger Zone

The Jagger Zone represents the largest and strongest soil geochemical anomaly yet discovered at Kossou. A strong north-south gold in soil anomaly has been identified over approximately 2 kilometer length with widths up to 500+ meters. Trenching has confirmed the soil anomaly and results are very encouraging. Recent surface rock chip sampling has exposed a new hydrothermal breccia zone with strong gold values: 10.30 g/t Au over 3.5 m and 4.90 g/t Au over 4.30 m. Trench results include 5.56 g/t Au over 6.20 m (KTR010 and 3.73 g/t Au over 4.55 m (KTR009).

Recently released sampling results for trench KTR028 (June 7, 2023) demonstrate excellent, multiple high-grade zones of gold mineralization. Multiple parallel zones of strong gold mineralization have been defined in the trench. Results include:

  • The most westerly zone features 6.42* g/t over 29.0 m, including sub-intervals of 18.04 g/t Au over 5 m, 11.44 g/t over 8 m and 5.53* g/t Au over 17 m
  • The second and more easterly shear zone featured 1.17* gpt Au over 27 m, including sub-intervals 1.62 g/t Au over 15.0 m, 5.38 g/t Au over 3.0 m and 0.82 g/t Au over 8.0 m

An additional NW-SE trending parallel zone (Jagger South Zone) is evident west of the main anomaly. KTR022 (1.15 g/t Au over 2.0 m) and KTR023 (0.8 g/t Au over 13.0 m, including 1.79 g/t over 4.0 m), represent an additional gold bearing structures that represent lower order targets for further exploration.

The Road Cut Zone (RCZ)

The Road Cut Zone is our primary target to date. 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.  Exposure along the road indicate this mineralization can be traced over a length of at least 110 meters and with a demonstrated width of approximately 15 meters.  The original exposure returned 4.64 gpt Au over an 18.2-meter continuous chip sampling program.  Further sampling to the north and south of this exposure along the road cut confirmed early gold results. 

Further rock sampling confirmed grades and expanded the extent of the showing.  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 drilling.  Recent trenching has also exposed a new mineralisation that assayed 11.30 g/t Au over 4.0 m (KTR003), 8.48 g/t Au over 5.00 m (KTR001) and 8.50 g/t Au over 3.4 m (KTR012)

Additional mapping, sampling and structural geology work has elevated the RCZ to a primary drill target for the 2023 drill program.

RCZ Soil Geochemistry and Trench Results 



Kobo has collected 3,156 soil samples excluding blank and duplicate samples.  Gold in soil geochemical results have outlined multiple anomalous trends including:

  • Beach-RCZ ~ 1.7 kilometer strike
  • Jagger ~1.7 kilometer strike (up to 500+ m width)
  • Jagger Sout ~2 kilometer strike
  • CZ ~ 5 kilometer of anomalous geochemistry 

All geochemical targets are supported with rock samples or extensive artisanal mining. These geochemical targets for the basis of the proposed drill program of 2023.


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 mineralization.  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.
