Deposits

 

Durba – Chauffeur – Karagba – Kibali and Sessenge Trend
 

These deposits are located in the 4.5km long Kibali-Durba-Chauffeur-Karagba mineralized corridor which hosts the Kibali deposit at its southern end and extends northeast, passing through the Sessenge deposit; the Durba Mine, a historical producer; the Chauffeur deposit and into the Karagba deposit. These deposits occur as a series of stacked NE plunging mineralised lodes which have excellent continuity in the down-plunge direction.

The ongoing drilling program is focused primarily on the Chauffeur and Karagba deposits as they contain the bulk of the gold mineralisation. The majority of the mineralisation is hosted in pyrite mineralised silica-carbonate-albite altered volcano-sedimentary sequence.

 

Pakaka and Pamao Trend
 

The Pakaka deposits were located, drilled, trenched and adit sampled by the Belgian's between 1956 and 1958. Apart from bulk sampling no mining was undertaken by OKIMO or the Belgians. Relatively minor artisanal mining has been undertaken generally in the upper 2 - 5 metres of the deposit.

The Pakaka mineralization is a shallow dipping 15-25°, northeast plunging sheetlike mineralised body averaging 10-40m in thickness. The mineralization starts at surface and drilling has intersected mineralization at vertical depths exceeding 270m (approx. 900m down plunge). The deposit has yet to be closed off down plunge. The southern mineralised shoot of the Pakaka Deposit has excellent potential for future underground exploitation due to its narrower high grade nature.

At the Pamao Deposit, which lies 500m west of the Pakaka Deposit, drilling has defined shallow northeasterly dipping (15-25°) mineralisation over a strike length of 500m and down dip for up to 350m, a vertical depth of less than 150m. The mineralised zone averages 15-25m thick. The deposit remains open down dip.

Gorumbwa

The Gorumbwa deposit consists of a series of elongated stacked lodes within a zone 100 to 180m long and approximately 50m thick traced down plunge to approximately 400m vertical depth (1,100m down plunge). The deposit remains open along strike and at depth.

Megi – Mengu Trend
 

The Megi–Mengu mineralised corridor is a large northwest trending mineralized trend traced over a distance of 4 kms. Drilling has demonstrated the presence of significant gold mineralization at Mengu Hill, Mengu Village, Marakeke and Megi.

At the Megi deposit, located in the eastern portion of the Megi-Mengu Trend, reconnaissance and infill RC drilling have defined shallow (15-25°) northeasterly dipping mineralisation over a strike length of 500m and down dip for up to 250m, a vertical depth of less than 90m. The mineralisation consists of two zones, an upper and a lower with the latter attaining thicknesses of up to 36m, averaging 15-20m. The upper is generally thinner, averaging 5-10m.
 

The Marakeke deposit starts 400m west northwest of the Megi Prospect. Drilling has traced the shallow northeasterly dipping (15-25) mineralisation over a strike length of 400m and down dip for 150m, a vertical depth of less than 60m. 
 

The Mengu Village deposit commences a further 800m to the northwest of the Marakeke Prospect.
 

Drilling at the Mengu Hill deposit located 450m south of the Mengu Village deposit has defined mineralisation is similar in style to the Chauffeur – Karagba deposits forming a 30° north northeast plunging on the northern dip slope of Mengu Hill.

Ndala

The Ndala Deposit is located 1.9km east of Pakaka and was the subject of pitting by OKIMO in the 1970's. An area 180m by 130m open in all directions was tested by 94 pits totalling 1,017.6m.

Kombokolo

The Kombokolo Prospect lies approximately 800m to the southeast of the old Agbarabo mine and is marked by artisanal workings over one of the main exploration drives established by the Belgians in the early 1960s.

 

 

Prospects

Preliminary regional work has already identified a number of exciting targets, including:

Rambi – Kiasi Prospect

A 70 sq km area of scattered alluvial artisanal workings and favourable geology centred 40km east of the Doko - Durba area. The relatively large Kiasi open pit apparently commenced production in 1955. Limited documentation is available, although ore from there was reported to have a recovered grade of 8g/t Au. Soil sampling at Rambi – Kiasi has delineated three targets within the Project area, the largest of those measuring 3km by 1.5km surrounding the Rambi – Kiasi mines.

Ndala North Prospect

Located 3km north of the Ndala Deposit, it was initially identified by soil geochemistry. Reconnaissance RC drilling has demonstrated gold mineralisation located on the contact of basalts and interflow sediments. Significant results from drilling to date have included 6m @ 3.91 g/t Au from 4m to 1m in NNRC025, 6m @ 2.89 g/t Au from 10m to 16m in NNRC037 and 6m @ 2.58 g/t Au from 28m to 34m in NNRC038.

Mofu – Oere – Kalimva / Ikamva and Kalimva North Prospects

Located on a 9.5km northwest striking mineralised trend commencing 2km northwest of the Mengu Hill Deposit. All of these prospects with the exception of Kalimva and Ikamva were delineated by soil geochemistry. Kalimva was mined by the Belgians between 1952 and 1957. Production records show 636,779 tonnes mined from 3 pits for a recovery of 22,015 ounces of gold. A further 122,630 tonnes yielding 6,528 ounces of gold was exploited at the Ikamva Mine located 1k west of Kalimva.

Reconnaissance RC drilling has been completed at Oere, Mofu and Kalimva North. Significant intercepts were returned from all 3 prospects. Further drilling to include the Kalimva and Ikamva Mines is planned.

Gawa

Is a geology generated soil geochemistry target, located 15km east of the Kibali – Durba – Chauffeur – Karagba Mineralised corridor. The target lies within the basalts on the western contact of a sodic granite. Gold in soil results to date have defined an anomaly measuring 700m x 150m as defined by the 25ppb Au contour.
