Kilo Goldmines Ltd. is pleased to announce that Randgold Resources Limited has provided the following update on the 2 057 km² Kilo - Randgold joint venture on the Ngayu and Isiro Archaean Greenstone Belts in Oriental Province, Democratic Republic of the Congo.
Highlights
- Regional soil sampling and geological mapping over the priority areas of the Isiro
- Belt is complete. All results have been received and 5 identified targets are highlighted.
- Infill soil sampling over the Yambenda target (Ngayu Belt) is complete and results confirm the 9.5 km x 200 m wide 50 ppb Au anomaly spatially associated with a ridge of banded iron formation.
- Trenching at Yambenda has commenced.
- Infill soil sampling at Mbese and Zimamoto (Ngayu Belt) has commenced in order to follow up on the Au-As association from the regional soil program.
Alex van Hoeken, President and CEO of Kilo, today stated:
"Our partner Randgold continues to methodically advance the exploration of the joint venture area, and it is very encouraging that, in addition to the previously identified targets in the Ngayu belt, the Isiro belt has also yielded areas of potential discovery thus enhancing the prospectivity of the entire joint venture area."
ISIRO BELT TARGETS
Regional soil sampling over the priority conceptual targets of the Isiro belt is complete, covering a total of 400 km2 (Figure 1). The soil samples (4841 in total) were taken from a 400 m x 200 m grid at ± 50 cm depth below the humus horizon. The samples were sun dried and sieved (-80#) at Isiro Camp before being sent to the SGS laboratory in Doko (Kibali) or Mwanza (in Tanzania). The samples were analysed by fire assay. Additional information including topography, grain size, colour, old/artisanal workings, farms, villages, roads, outcrop and regolith were recorded during sampling. In addition, 76 rock samples were taken with results from the SGS laboratory pending.
All soil sample results have been received, highlighting five identified targets described below in order of priority. Regional form line analysis, constructed at 1:25000 scale (Figure 1b), was completed to assess whether any of the anomalous areas coincide with structural discontinuities.
Logistical issues have thus far limited the amount of data gathered at the extreme east of the Isiro Belt.
Bodjo Target
Gold in soil results reveal a 4 km x 500 m WNW trending anomaly at 30 ppb including 1 km x 150m @ 100 ppb. A second anomaly to the east measures 2.2 km x 400 m @ 30 ppb. The anomalies overlie insitu material associated with a WNW trending topographic high transected by southerly flowing rivers. Several artisanal workers are panning the rivers for gold. A large laterite plateau lies to the north of the anomaly.
Mangabi Target
Gold in soil results reveal a 7.5 km x 500 m WNW trending anomaly at 30 ppb including a 1.5 km x 500 m 70 ppb anomaly. The anomaly is cut by southerly flowing drainages in the east, and north flowing rivers in the west. Although the western limit of this anomaly is suspected to be proximally transported, the highest values (530 ppb) within the anomaly overly a small hill. Numerous artisanal workers are panning for gold along the rivers.
Bamungo Target
Gold in soil results reveal a 4 km x 400 m WNW to NW trending 30 ppb anomaly including a 400 m x 400 m central zone with values greater than 100 ppb. The soil anomaly lies between two prominent hills and may represent proximally transported material.
Adjolia Target
Gold in soil results reveal a 3.8 km x 1.5 km apparent NS trending 30 ppb anomaly that crosscuts the stratigraphy and is possibly transported. Within the southern half of the 30 ppb anomaly a WNW trending zone with higher values of 80 - 130 ppb parallels a major thrust. This high-grade region is thought to be the source of the anomaly, as well as the center of the apparent NS trend.
Pande Target
Gold in soil results reveal that the Pande target is essentially two sub parallel NW trending
30 ppb anomalies. The anomalies crosscut the regional stratigraphy and do not appear to be related to the thrust package, as seen at the Adjolia target. The western anomaly measures 2.8 km x 400 m and is associated with a WNW trending package of banded iron formation ("BIF") and fine grained metasediments (siltstone), whilst the eastern anomaly of 4 km x 150 m traverses a major river (Nava River) and appears to be transported.

KILO - RRL JV GEOLOGY
The JV property is underlain by Archaean rocks of the Ngayu and Isiro Greenstones Belts, as illustrated in Figures 1 and 3. The greenstone belts are comprised of Upper Kibalian metasedimentary rocks, BIF, mafic volcanics, and mafic to felsic intrusive rocks.
SOIL SAMPLING PROCEDURES
The regional soil samples were collected at a depth of approximately 50 cm, below the humus horizon, at 200 m intervals on lines 400 m apart. Sample sites were located by GPS and coordinates were recorded for each site. Approximately 2 kg of material present at the depth sampled was collected and placed into a plastic bag together with a pre-numbered sample tag and the bag was securely closed. Topographic, grain size, colour, old/artisanal workings, farms, villages, roads, outcrop and regolith data was recorded during sampling.
Sampling was carried out by up to seven sampling teams, each led by a Congolese geologist. Kilo provided logistical support as well as sampling teams comprised of technical and casual labour that reported to Randgold senior geologists.
QUALITY CONTROL AND ANALYTICAL PROCEDURES
Sample preparation consisted of sorting the samples into sequential numerical order, followed by drying (regional soil samples from the Ngayu Belt were dried at 90°C in the Adumbi kiln while the samples from Isiro were sundried), and sieving to -80 mesh (80 microns) Randgold delivered the sample pulps to the SGS Laboratory in Doko, DRC. Both SGS in Mwanza and Doko analyzed the samples using a 50 g charge by Fire Assay with Atomic Adsorption; SGS method, FA505.
Analytical quality control consisted of the insertion of commercial blank and standard reference material in every batch of samples submitted for analysis.
