African Metals Corporation (TSX VENTURE:AFR)(FRANKFURT:OWW) has provided an update on exploration activities at its Luisha South Project in the Democratic Republic of the Congo.
Summary
A total of 200 metres of scout Reverse Circulation (RC) drilling from four holes was completed at the Luisha South Project in October 2010. The holes targeted four copper-in-soil geochemical anomalies highlighted by a regional soil sampling program. Analytical results of the RC samples indicate that two of the holes have intersected significant levels of low grade copper mineralization associated with a northwest trending ridgeline:
44m at 0.20% copper, 0.03% cobalt (from 6m – LURC021)
50m at 0.30% copper, 0.08% cobalt (from 0m – LURC022)
Luisha South Project RC Drilling
Magnum Drilling Sprl completed a 200 metre reverse circulation (RC) drilling program at the Luisha South Project in October 2010. A total of four x 50m vertical scout holes (LURC021 to LURC024) were drilled to test copper in soil geochemical anomalies highlighted by regional soil sampling programs.
Drill holes LURC021 and LURC022 tested broad anomalies located well south of the pit at the break of slope of a northwest trending ridgeline. Both holes intersected maroon to red siltstone and fine grained sandstone. A dark grey to black sub-metallic mineral, possibly manganese, occurred in variable amounts in the upper portions of the holes. The mineralization is interpreted as being associated with this mineral, and samples have been dispatched for petrologic review. Malachite mineralization was not observed in the drill chips.
Drill holes LURC023 and LURC024 tested anomalies along strike to the southeast of the pit. LURC023 intersected malachite in the first metre, explaining the 0.39% copper in soil anomaly. The malachite possibly representing float fragments within the soil profile. Malachite was not observed in the remainder of the hole. Drill Hole LURC024 did not intersect malachite mineralization. Both LURC023 and LURC024 returned anomalous values of magnesium (an indicator mineral) which requires further investigation.
Both LURC23 and LURC024 drilled through soil cover and onwards into sedimentary breccia, possibly of the Red RAT Formation. Minor sulphides were noted in the unit. Diamond tails are planned for both holes to test the model of the breccia overlying mineralized dolomitic units, as observed in LURC004 which intersected 8m of copper and cobalt mineralized sediments beneath the overlying Red Rat unit. Drill hole LURC004 was the south-eastern most hole completed in the June 2010 RC drilling program.
The host formation for both LURC021 and LURC022 is interpreted as being Lower Kundelungu (Mwasha); the unit may represent a new target horizon for the project.
Samples were collected from all four RC holes at one metre intervals, and riffle split to produce approximately one kilogram sub-samples which were combined to produce a 2m composite for analysis. A total of 124 samples including QC controls were dispatched to ALS Laboratories in Johannesburg, South Africa, for sample processing and analysis. All samples were analyzed by method MEICP61 following sample prep and a 4 acid digest. The analytical results of the QC samples (standards, blanks, and field duplicates) were within acceptable limits.
Positive assay results from the RC program indicate that the southern soil anomalies warrant further investigation. AFR plans to conduct follow up drilling operations in 2011 after the end of the current wet season (March, April).
