Pensana Rare Earths Plc (ASX: PM8) has significantly extended the know mineralised areas at its Longonjo NdPr Project in Angola.
The results from a further 18 holes of the recently completed 7000 metre drill programme at Longonjo include further high-grade intersections from angled holes testing two mineralised contact zones well outside of the Preliminary Feasibility Study (PFS) pit design.
- Southern margin: results have extended NdPr mineralisation associated with sub vertical mineralised carbonatite dykes up to 25m wide within the contact zone of the Longonjo Carbonatite.
- North east margin: results have defined a 400m zone of strong weathering up to 200m wide and 80m deep containing rare earth mineralisation with elevated NdPr content. Mineralisation remains open along strike to the north and south.
Executive Director and COO Dave Hammond said the company expects that these latest results will allow these areas of Inferred mineral resource to be upgraded to Indicated category, allowing its inclusion into the mine plan on completion of the Definitive Feasibility Study work programmes.
These latest results demonstrate the continuity of large areas of Inferred resources outside the PFS pit design which along with the previous results we are expecting will significantly extend the mine life in the Definitive Feasibility Study.
“We are very much looking forward to the results from the outstanding 120 holes. The majority are infill holes within the high-grade area of the PFS pit design and include several deeper holes which are testing an area immediately below the PFS pit design where previous drilling had intersected high grades in fresh rock.”
The current DFS drilling programme is designed to extend the November 2019 PFS mine life through the conversion of the large areas of Inferred category Mineral Resource to Indicated through infill drilling. The majority of the Inferred mineralisation was excluded from the PFS mine plan.
