CALGARY, ALBERTA--(Marketwire - Nov. 14, 2011) - Mkango Resources Ltd. (TSX VENTURE:MKA) (the "Corporation" or "Mkango") is pleased to announce results for the remaining three holes (PX027, PX030 and PX031) of the Stage 1 drilling programme at the Songwe project in Malawi. Highlights from the new results are as follows:
||81.5m grading 1.3% TREO (20.3 – 101.8), including 18.7m grading 2.1% TREO (80.0 – 98.7m), and 18.3m grading 1.5% TREO (170.0 – 188.3 EoH). PX027 ended in mineralisation.
||13.0m grading 1.4% TREO (68.0 – 81.0m). Between 81.0m and the end of hole at 136.2m, PX031 intersected zones of broken ground grading up to 5.6% TREO. This zone will be further tested in a subsequent phase of drilling. PX031 ended in mineralisation.
TREO: total rare earth oxides
See Appendix for contents of TREO and for further details on results of Stage 1 drilling programme.
These intersections are reported as down hole widths and do not necessarily represent true thicknesses and attitude of the mineralised zones, the estimation of which will require further drilling and refining of the geological model. PX030 successfully demonstrated the extension of the Songwe vent system to the east. While there were no significant core intersections over 1% TREO in PX030, both light rare earth and heavy rare earth mineralisation at lower grades was intersected throughout the hole with sporadically higher grades up to 2.7% TREO.
The main highlights from the first phase of exploration are as follows:
- Eleven of the thirteen holes drilled in Stage 1 intersected significant zones of rare earth mineralisation, including higher grade zones and areas of heavy rare earth enrichment. Drilling and surface mapping to date have confirmed that the extent of the mineralised carbonatite is much greater than indicated by historical exploration
- Drilling, surface mapping and sampling has outlined TREO enriched carbonatite, fenite and breccia lithologies, largely exposed at surface, within an area measuring approximately 350m by 20-150m, with mineralisation open to depth. This area will be the focus of the next phase of drilling.
- Rare earth mineralisation, in addition to niobium mineralisation, is pervasive throughout the carbonatite, breccia and fenite lithologies and there appears to be a separate phase of heavy rare earth and yttrium enriched mineralisation which extends well beyond the carbonatite zones
- Mineralogical analysis of the rare earth bearing lithologies is well advanced and representative sections of core are now being selected for scoping metallurgical test work to commence in 2012
- Exploration has recently identified two breccia zones within 3km of Songwe with highly anomalous yttrium values as analysed by a hand held niton XRF
- Regional exploration has commenced, targeting other known vent systems, breccia zones and other new exploration targets identified through satellite imagery and analysis of radiometric data
Systematic channel sampling using rock saws is underway at Songwe with a view to further delineating and extending rare earth mineralisation at surface. Geological mapping and sampling is focused on refining the geological model and delineating additional zones of mineralised carbonatite, breccia and fenite.
The next phase of drilling will focus on the aforementioned 350m by 20-150m area, infilling previous drilling and testing depth extensions. A central gravity anomaly will also be tested.
Sample preparation and analytical work for the drilling programme is being provided by Intertek- Genalysis Laboratories (Johannesburg, South Africa and Perth, Australia) employing ICP-MS techniques suitable for rare earth element (REE) analyses and following strict internal QAQC procedures inserting blanks, standards and duplicates. Mkango has used blanks, field duplicates and two Certified Reference Materials (CRM's) to monitor sampling and analytical quality. Results to date for the blanks and field duplicates show acceptable quality. The two CRMs used (AMIS 184 and SARM 40) showed acceptable results within the certified parameters provided. A review of results reported by Genalysis and peformed by The MSA Group, an independent, South Africa based, mineral exploration, evaluation and environmental consulting group, indicates that these meet the required level of analytical quality.
Scientific and technical information, including data verification, contained in this release has been approved and verified by Mr Mike Venter Pr.Sci.Nat, Principal Consultant at The MSA Group who is a "Qualified Person" in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects.
Mkango Resources Ltd.
Mkango's primary business is the exploration for rare earth elements and associated minerals in the Republic of Malawi. It holds, through its wholly owned subsidiary Lancaster, a 100% interest in two exclusive prospecting licenses covering a combined area of 1,751 km² in southern Malawi. The main exploration target is the Songwe Hill rare earth deposit, which features carbonatite hosted rare earth mineralisation and was subject to previous exploration in the late 1980s.
The Corporation's corporate strategy is to further delineate the rare earth mineralisation at Songwe Hill and secure additional rare earth element and other mineral opportunities in Malawi and elsewhere in Africa.
