Re-commencement of Resource Drilling at Africo’s Kalukundi Copper-Cobalt Project
Also, near surface drilling on Kii and Kalukundi Fragments will define
near surface mineralization for mine planning.
VANCOUVER, May 9, 2012 /CNW/ – Africo Resources Ltd. (“Africo”)
(TSX:ARL) is pleased to report that the resource drilling has been
re-commenced on its Kalukundi Project in the Democratic Republic of
Congo (DRC). A total of 46 boreholes on 4 fragments (5430m) have been drilled from June 2011 to the end for March 2012. Assay data
is at hand for the initial boreholes drilled on the Principal Fragment
and this data provides confirmation of the high grade values previously
drilled on this fragment.
The drilling programme was focused on the copper and cobalt rich
Principal Fragment. The objective has been to prove continuity of the
geology and grade at 50 metre intervals, to establish the nature and
extent of the mineralisation in both the Mines Series and the
hangingwall formations and to drill down to the sulphide zone to
confirm continuity and grade of the main Mines series mineralisation.
All of these objectives were achieved and in some cases with excellent
results (Ref table 1).
Drilling then moved to the Kii and Kalukundi Fragments where a smaller
track mounted rig could access the steep hills and drill the near
surface, previously inaccessible zones. Some drilling was undertaken
of the SE Anticline Fragment. Finally, drilling has moved to and is in
progress on a fifth fragment, the Anticline Fragment.
A brief description of the results is outlined below section by section
to compare the current results listed in Table 1 with the results of
previous nearby, but more shallow drilling data.

The drilling results are reviewed starting from the NW of Section 8 with BHs PCPD007 and 8. These results compare well with that of BH K3
drilled previously by JCI. They confirm high grade mineralisation in
the Upper and Lower Ore bodies especially. Near surface at a depth of
40m, BH K54 demonstrates that the Lower Ore Body is best mineralized,
whereas the RSC and Upper Ore bodies are weakly mineralised. The
values of 3.61% Cu and 1.05% Co over 37.80m in BHK3 compare well with
those in BH PCPD007 especially and continuity down to PCPD008 at a
vertical depth of 130m is also excellent. This demonstrates improving
grade of mineralisation in depth to K3 and deeper.
On section 6 BHs PCPD005 and 6 can be defined as high grade intersections over the
full extent of the Mines Series units. These two boreholes straddle BH
KDI1 drilled by Gecamines, which intersected 3.14% Cu and 0.58% Co over
a width of 38.60m. The new intersections demonstrate much improved
copper and especially cobalt mineralisation and substantiate excellent
continuity of the mineralised zone.
Section 5 has two new boreholes drilled between the near surface and a deep
borehole. The two BHs, PCPD003 and 4 demonstrate a similar
mineralisation distribution to the previous holes, with most of the
high grade values occurring in the Lower Ore body. These intersections
warrant a separate table to emphasize the concentration of high grade
mineralisation in the Lower Ore Body as follows:-
_____________________________________________________________________ | BH No | From| To |Interval|Cu %|Co %| Comments |Section No| |_______|______|______|________|____|____|_________________|__________| |PCPD003| 80.80|94.24 | 16.44 |8.04|3.73|RSF,D Strat & RAT|Section 3 | | | | | | | | Grise units | | |_______|______|______|________|____|____|_________________|__________| |PCPD004|120.60|131.00| 10.40 |6.09|0.92| RSF and D Strat |Section 3 | | | | | | | | units | | |_______|______|______|________|____|____|_________________|__________|
On section 4 a single hole, PCPD002 intersecting at a vertical depth of 90m has
returned encouraging values which are very similar, but slightly lower
than the intersection in BH K4 at a shallower depth. In each borehole,
the SDB and RAT Grise (upper and lower units) are almost devoid of
On section 3 again a single borehole can be compared with the shallow BH K52 which
intersected the Lower ore body only with very high grade copper
mineralisation (6.25% Cu and 0.61% Co over 15.55m). Here the deeper
intersection in BH PCPD001 intersects a much wider zone of
mineralisation with lower copper, but higher cobalt values overall. As
on section 8, this demonstrates more extensive mineralisation in depth.
On section 1 Boreholes PCPD009 and 010 in the south-east were drilled virtually on
the edge of or within the fault zone on the SE extent of the Principal
Fragment. BH 9 intersected mainly cobalt mineralization in the Lower
Ore Body, whereas BH10 encountered no mineralisation. Excellent
mineralisation was intersected in the percussion water hole drill
nearby (KALKP007 drilled 4.58% Cu and 1.90% Co over 15.00m) on this
It must be emphasized that the above drilling is essentially within the
oxide zone and the ore minerals intersected are dominated by malachite
(Cu) and heterogenite (Co).
Assay values are available for two deeper boreholes drilled to test the
hangingwall mineralization and the grade within the sulphide zone for
the deeper Mines series intersections. Both boreholes were successful
in traversing a well mineralised Mines Series package. On section 3, BH PCPD012 was drilled downdip from BH PCPD001. The SBD is
mineralised, but the RSC is weakly mineralised, which is often the case
in the sulphide zone where no secondary enrichment has occurred except
near the upper and lower contact zones. Here the Footwall Ore Zone is
very well mineralised and it shows a close comparison with BHs K52 and
PCPD001, as follows:

Finally the deep hole on Section 7 is BH PCPD011C. This borehole shows a similar mineral distribution in
the Mines series to the three holes on section 3 as detailed above with
the best mineralisation occurring in the Upper and Lower Ore Bodies.
In the case of BH 11C, the mineralisation in the RSC is very weak as is
generally the case in the sulphide zone.
Varying amounts of mineralisation have been intersected in the hangingwall units above the Mines Series. These are the CMN dolomite and shale units and
the SDS shales. One of the best intersections is that listed above in
BH PCPD011C (Table 1). This compares well with the intersection in the
adjacent borehole drilled above, namely K109:-

Numerous intersections with varying amounts of copper and to a lesser
degree cobalt mineralisation have been intersected in this campaign in
the hangingwall units. A full assessment of the hangingwall
mineralisation still needs to be undertaken to fully understand the
potential of this mineralisation in contributing to the resources of
the Principal Fragment at Kalukundi. Establishing continuity of these
units will take some time and hence cannot be discussed in more detail
Assay results are still awaited for boreholes PCPD013, 14 and 15. In
addition, assay data is still awaited from the near surface drilling on
the Kii and Kalukundi Fragments.
1. All drilled thicknesses listed above are apparent widths. No adjustment has been made for the dip of the formations. The angle of dip of the formations varies from about 75º to about 50º. The angle of the drill holes are consistent at -45º, hence there is a small discrepancy in which the true widths will be slightly narrower than the apparent widths. 2. Mention is made of the Upper Ore Body and the Lower Ore Body. Although this is a mining term on the DRC Copperbelt it has over time become accepted terminology for these two zones above and below the RSC (or siliceous dolomite) unit. It does not necessarily infer economic concentration of mineralisation. 3. Sample preparation is done on site in the DRC. Analyses were undertaken by ALS Chemex in Johannesburg. The pulp is received and sieved to 95%-106µ. Three analysis techniques are used; ICP-AES analyses by ME-ICP61 on 33 elements after 4 acid digestion; ICP-AES analyses by ME-OG62 on ore grade elements after 4 acid digestion.
